Description

照明裝置Lighting device

本發明是有關於一種主要在道路、公園等室外用作路燈、防犯燈、庭院燈、及投光器等的照明裝置。The present invention relates to a lighting device that is mainly used as a street light, a crime light, a garden light, a light projector, and the like, mainly in roads, parks, and the like.

一般來說，此種照明裝置安裝在設置于道路的人行道側的支柱等的高處，將螢光燈(lamp)或高強度放電(High Intensity Discharge)燈作為光源來對路面進行照明。但是，近年來，從節能化或免維護等的觀點考慮，正在研究將發光二極體(diode)用作室外照明裝置的光源。Generally, such an illuminating device is attached to a high point of a pillar or the like provided on a sidewalk side of a road, and illuminates a road surface using a lamp or a high intensity discharge lamp as a light source. However, in recent years, from the viewpoints of energy saving or maintenance-free, etc., a light source diode has been studied as a light source of an outdoor lighting device.

對於進行室外照明的防犯燈而言，必須以適當的亮度來對路面進行照明，需要具有適合防盜照明的推薦照度(recommended illuminance)。也就是說，需要以水平面照度(平均值)為3勒克斯(lux)、鉛垂面照度(最小值)為0.5勒克斯的方式來對防犯燈進行設置，以達到能看到行人的舉動及姿勢等的照明效果。同時，需要盡可能地藉由擴大防犯燈的設置間隔來降低設置成本，要求經濟地獲得廣範圍的配光。For a security light for outdoor lighting, the road surface must be illuminated with appropriate brightness, and a recommended illumination (illuminated illuminance) suitable for anti-theft illumination is required. In other words, it is necessary to set the security lights in such a way that the horizontal illuminance (average value) is 3 lux and the vertical illuminance (minimum value) is 0.5 lux, so that the behavior and posture of the pedestrian can be seen. Lighting effect. At the same time, it is necessary to reduce the installation cost by expanding the setting interval of the security light as much as possible, and it is required to economically obtain a wide range of light distribution.

因此，已提出專利文獻1所示的使用著白色發光二極體的室外照明器具。在此室外照明器具中，安裝著多個白色發光二極體的多個平面印刷基板是以白色發光二極體指向下表面側、而且指向其他方向的方式而裝配多個成多角形狀。Therefore, an outdoor lighting fixture using a white light-emitting diode as shown in Patent Document 1 has been proposed. In the outdoor lighting fixture, a plurality of flat printed substrates on which a plurality of white light-emitting diodes are mounted are mounted in a plurality of polygonal shapes such that the white light-emitting diodes are directed to the lower surface side and are directed in other directions.

然而，如專利文獻1所示，為了利用如發光二極體那樣的發光部較小的光源，來獲得如防犯燈那樣對道路進行照明的配光，必須排列地使用大量的發光二極體，因而會產生成本方面的問題，並且構造變得複雜，組裝作業也變得煩雜。However, as shown in Patent Document 1, in order to obtain a light distribution that illuminates a road like a light-proof lamp by using a light source having a small light-emitting portion such as a light-emitting diode, a large number of light-emitting diodes must be used in series. Therefore, there is a problem in terms of cost, and the configuration becomes complicated, and the assembly work becomes complicated.

因此，對於此種將發光二極體等的發光元件作為光源的防犯燈等的照明裝置而言，重要問題在於如何實現即使簡化發光元件的排列，仍能對道路進行廣範圍照明的照明裝置。Therefore, an illumination device such as a light-proof lamp or the like that uses a light-emitting element such as a light-emitting diode as a light source has an important problem in how to realize an illumination device capable of wide-ranging a road even if the arrangement of the light-emitting elements is simplified.

另外，發光二極體雖小，但發光強度高。因此，如專利文獻1那樣為了向多個方向照明而使用了大量的發光二極體的照明裝置的亮度高，且容易讓人感到刺眼(glare)。Further, although the light-emitting diode is small, the light-emitting intensity is high. Therefore, as in Patent Document 1, the illumination device using a large number of light-emitting diodes for illuminating in a plurality of directions has high luminance and is easily glare.

本發明的目的在於提供一種能簡化發光元件的排列，能進行廣範圍照明，而且能減小眩目感的照明裝置。An object of the present invention is to provide an illumination device which can simplify the arrangement of light-emitting elements, can perform wide-range illumination, and can reduce glare.

第1發明的光源模組(module)的特徵在於包括：模組基板；發光元件，直線狀地安裝在所述模組基板上；以及反射構件，在寬度方向中央部具有配置著所述發光元件的長孔、以及從所述長孔的兩側的邊緣向與所述長孔相對向的開口擴開的反射面，所述反射構件具有與所述反射面連續地形成且將長度方向的上端封閉的反射壁部，並且將下端開放。A light source module according to a first aspect of the invention includes: a module substrate; a light emitting element linearly mounted on the module substrate; and a reflection member having the light emitting element disposed at a central portion in a width direction a long hole, and a reflecting surface extending from an edge of both sides of the long hole toward an opening facing the long hole, the reflecting member having a continuous end formed with the reflecting surface and having a length direction The closed reflective wall portion is open and the lower end is open.

在第1發明中，光源模組的發光元件優選發光二極體(LED)或半導體激光等將半導體作為發光源的發光元件，當所述發光元件為LED時，可較佳地使用例如表面安裝元件(Surface Mounted Devices，SMD)型的LED。可任意地選定構成發光元件列的發光元件的個數、以及光源模組的個數。構成發光元件列的多個發光元件優選具有相同功能及性能，但也可由功能、性能不同的發光元件所構成。In the first aspect of the invention, the light-emitting element of the light source module is preferably a light-emitting element using a semiconductor as a light-emitting source such as a light-emitting diode (LED) or a semiconductor laser, and when the light-emitting element is an LED, for example, surface mounting is preferably used. LED of the Surface Mounted Devices (SMD) type. The number of light-emitting elements constituting the light-emitting element row and the number of light source modules can be arbitrarily selected. The plurality of light-emitting elements constituting the light-emitting element row preferably have the same function and performance, but may be composed of light-emitting elements having different functions and properties.

反射壁部可以是平坦面，也可以是由向發光元件列的上端靠近的曲面等所構成的凸面，或者也可以是相反地由遠離發光元件列的上端的曲面等所構成的凹面。The reflecting wall portion may be a flat surface, or may be a convex surface formed by a curved surface or the like that is close to the upper end of the light emitting element row, or may be a concave surface that is formed by a curved surface or the like that is away from the upper end of the light emitting element row.

在形成反射構件的合成樹脂等的成形體的表面上覆蓋鋁或銀等的金屬製光反射膜，借此，可使反射面和反射壁部成為鏡面。A metal light-reflecting film such as aluminum or silver is coated on the surface of the molded body such as a synthetic resin forming the reflecting member, whereby the reflecting surface and the reflecting wall portion can be mirror-finished.

第2發明的照明裝置的特徵在於包括：器具本體；一對安裝部，配設在所述器具本體上，且彼此的背面傾斜地相對向；以及多個如第1發明所述的光源模組，在與所述發光元件的排列正交的方向上，並排設置於所述各個安裝部，且設置成靠近反射壁部的已開放的下端。An illuminating device according to a second aspect of the present invention includes: an illuminating device; a pair of mounting portions disposed on the luminaire main body and having opposite rear sides thereof obliquely facing each other; and a plurality of light source modules according to the first aspect of the invention, The respective mounting portions are arranged side by side in a direction orthogonal to the arrangement of the light-emitting elements, and are disposed adjacent to the opened lower end of the reflective wall portion.

第2發明的照明裝置可較好地用作道路、公園等中的進行照明的防犯燈等的室外照明裝置，也可用作設置在如下的場所中的室內用照明器具，此場所是指在室內的走廊或通道等的長度方向(道路等的延伸方向)上需要規定的亮度的場所。The illuminating device according to the second aspect of the invention can be preferably used as an outdoor illuminating device for lighting, such as a road, a park, or the like, and can be used as an indoor lighting device installed in a place where the A place where a predetermined brightness is required in the longitudinal direction of the hallway or the passageway (the direction in which the road or the like extends).

當將第2發明中的照明裝置例如用於防犯燈時，優選從器具本體的兩側向斜下方射出光，以沿著道路的長度方向而獲得廣範圍的配光。When the illuminating device according to the second aspect of the invention is used, for example, for a tamper-proof lamp, it is preferable to emit light obliquely downward from both sides of the luminaire main body to obtain a wide range of light distribution along the longitudinal direction of the road.

在第2發明中，反射壁部將從發光元件向上方放射出的光向下方反射，因此，從發光元件發出的光不會向照明裝置的上方漏出而被浪費。借此，可實現能夠確保照明裝置的大致正下方的亮度的照明，並且可減小因光向照明裝置的上方漏出而產生的光污染(light pollution)。In the second aspect of the invention, since the reflection wall portion reflects the light radiated upward from the light-emitting element downward, the light emitted from the light-emitting element does not leak to the upper side of the illumination device and is wasted. Thereby, illumination capable of ensuring the brightness substantially directly below the illumination device can be realized, and light pollution due to leakage of light to the upper side of the illumination device can be reduced.

在第2發明中，器具本體優選由例如鋁壓鑄件(aluminium die cast)等構成的金屬、或不透光之合成樹脂等構成，從而將光阻斷，但也可在不會形成光障礙的範圍內允許有少許的漏光。In the second aspect of the invention, the luminaire main body is preferably made of, for example, a metal made of an aluminum die cast or the like, or a opaque synthetic resin, to block light, but it is also possible to form a light barrier. A small amount of light leakage is allowed in the range.

根據第2發明，以所述反射壁部位於上側，所述反射構件的已開放的下端相互靠近的方式，傾斜地設置第1發明的光源模組，並且將此光源模組分別並排設置在與發光元件的排列正交的方向上，因此，可簡化發光元件的排列。而且，各光源模組包括具有反射面的反射構件，可借由此反射構件來對發光元件所發出的光的配光進行控制而進行照明，因此，可借由分別並排設置在與發光元件的排列正交的方向上的光源模組來進行廣範圍的照明。而且，組合到反射構件上的發光元件的排列配設在設置於反射構件的寬度方向中央部的長孔內，因此，發光元件列會分別映入到收容著發光元件列的反射面的寬度方向的兩側部位，藉此，儘管發光元件較小且亮度高，但照明裝置在視覺上的光源的大小會因映入到反射面上的發光元件列的像而變大。因此，可減小由多個光源模組構成之光源產生的眩目感。According to the second aspect of the invention, the light source module of the first aspect of the invention is disposed obliquely such that the reflective wall portion is located above the open end of the reflective member, and the light source modules are respectively arranged side by side and illuminated. The arrangement of the elements is orthogonal to each other, and therefore, the arrangement of the light-emitting elements can be simplified. Moreover, each of the light source modules includes a reflecting member having a reflecting surface, and the light reflecting by the light emitting element can be controlled by the reflecting member to illuminate, and therefore, can be disposed side by side with the light emitting element The light source modules in the orthogonal directions are arranged for a wide range of illumination. Further, since the arrangement of the light-emitting elements combined on the reflection member is disposed in the long hole provided in the central portion in the width direction of the reflection member, the light-emitting element rows are respectively reflected in the width direction of the reflection surface in which the light-emitting element row is accommodated. On both sides, the size of the visual light source of the illumination device becomes larger due to the image of the light-emitting element array reflected on the reflection surface, although the light-emitting element is small and has high brightness. Therefore, the glare generated by the light source composed of the plurality of light source modules can be reduced.

第3發明的照明裝置的特徵在於：所述反射構件具有固定部，此固定部在所述反射構件的寬度內向上方及下方突出，用以配設到所述器具本體上。In the illuminating device according to a third aspect of the invention, the reflecting member has a fixing portion that protrudes upward and downward within a width of the reflecting member for being disposed on the luminaire body.

在第3發明中，在沿著與發光元件的排列正交的方向而彼此鄰接的光源模組之間，並未設置著用以將光源模組固定的固定部，因此，可使鄰接的光源模組彼此相互靠近地配設。藉此，可促進照明裝置的緊湊化(compact)，並且由多個光源模組構成、且沿著與發光元件的排列正交的方向延伸的光源在視覺上的大小，在鄰接的光源模組之間連成一體而無中斷。換而言之，所述光源在視覺上容易被認作仿佛是沿著器具本體的長度方向延伸的一個光源。According to the third aspect of the invention, the light source module adjacent to each other in the direction orthogonal to the arrangement of the light-emitting elements is not provided with a fixing portion for fixing the light source module, and therefore, the adjacent light source can be provided. The modules are arranged close to each other. Thereby, the compactness of the illumination device can be promoted, and the light source formed by the plurality of light source modules and extending in a direction orthogonal to the arrangement of the light-emitting elements is visually sized in the adjacent light source module. Connected together without interruption. In other words, the light source is visually recognizable as if it were a light source extending along the length of the body of the appliance.

根據第2發明或第3發明，第4發明的照明裝置的特徵在於：所述光源模組包括模組基板，此模組基板具有嵌合部且被所述器具本體的安裝部和所述反射構件的背面夾住並固定，所述反射構件包括：嵌合凸部，嵌合於所述嵌合部來將所述模組基板定位；以及扣合爪，扣合於所述模組基板的周緣來將所述模組基板保持於所述反射構件的背面。According to a second aspect of the invention, in the illumination device of the fourth aspect of the invention, the light source module includes a module substrate having a fitting portion and the mounting portion of the device body and the reflection The back surface of the member is clamped and fixed, and the reflective member includes: a fitting protrusion that is fitted to the fitting portion to position the module substrate; and a fastening claw that is fastened to the module substrate The periphery of the module substrate is held by the periphery of the reflective member.

在第4發明中，可利用嵌合部與嵌合凸部的嵌合來將模組基板定位於反射構件，因此，可將發光元件的排列相對於反射構件的反射面而組合到適當的位置上。而且，使扣合爪扣合於模組基板的周緣，從而可在將模組基板保持在反射構件的背面的狀態下，將光源模組組裝到照明裝置中。另外，發光元件並不被反射構件覆蓋，而是配置在此反射構件的長孔內，因此，例如，當發光元件如LED等那樣隨著發熱而發光時，反射構件不會妨礙發光元件的散熱。因此，能抑制發光元件的溫度上升，不會使發光性能等下降。特別是在照明裝置不具有覆蓋光源模組的外罩的構成中，發光元件所散發出的熱不易滯留在反射面的內側等，因此，可進一步抑制發光元件的溫度上升。According to the fourth aspect of the invention, since the module substrate can be positioned by the fitting member by the fitting of the fitting portion and the fitting convex portion, the arrangement of the light emitting elements can be combined with the reflecting surface of the reflecting member to an appropriate position. on. Further, the fastening claw is fastened to the periphery of the module substrate, and the light source module can be assembled in the illumination device while the module substrate is held on the back surface of the reflection member. Further, the light-emitting element is not covered by the reflective member, but is disposed in the long hole of the reflective member, and therefore, for example, when the light-emitting element emits light with heat like an LED or the like, the reflective member does not hinder heat dissipation of the light-emitting element. . Therefore, it is possible to suppress an increase in temperature of the light-emitting element without deteriorating the light-emitting performance and the like. In particular, in the configuration in which the illumination device does not have the cover covering the light source module, the heat emitted from the light-emitting element does not easily stay inside the reflection surface, and the temperature rise of the light-emitting element can be further suppressed.

另外，在第4發明中，可由金屬或合成樹脂來形成安裝部，但當發光元件為LED時，優選由鋁壓鑄件等金屬製成的所述安裝部，以可導熱的方式將LED配設在此安裝部上，藉此來促進LED的散熱。Further, in the fourth aspect of the invention, the mounting portion may be formed of a metal or a synthetic resin. However, when the light-emitting element is an LED, the mounting portion made of a metal such as an aluminum die-casting material is preferably provided to thermally dispose the LED. On this mounting portion, thereby promoting heat dissipation of the LED.

安裝部的截面可大致呈V字形，且可將多個光源模組分別配置在彼此的背部相對向的V字的一對兩邊部上，但安裝部的截面形狀並不限於V字形，也可為U字形。總之，可以採用以來自多個光源模組的光的照射方向大致對稱的方式而配置的所有的安裝部。The cross section of the mounting portion may be substantially V-shaped, and the plurality of light source modules may be respectively disposed on a pair of two sides of the V-shape opposite to each other on the back side, but the cross-sectional shape of the mounting portion is not limited to the V shape. It is U-shaped. In short, it is possible to adopt all the mounting portions that are arranged in such a manner that the irradiation directions of the light from the plurality of light source modules are substantially symmetrical.

根據第4發明，第5發明的照明裝置的特徵在於：包括覆蓋所述安裝部及多個光源模組且支撐於所述器具本體的透光性的外罩，此外罩包括：第1透光部，配設成與由所述光源模組的反射面所反射的光的出射方向大致正交；以及第2透光部，配設成與由所述反射壁部向下方反射的光的出射方向大致正交。According to a fourth aspect of the invention, the lighting device of the fifth aspect of the invention includes a light-transmitting cover that covers the mounting portion and the plurality of light source modules and is supported by the device body, and the cover includes: a first light transmitting portion And arranged to be substantially orthogonal to an emission direction of the light reflected by the reflection surface of the light source module; and the second light transmission portion is disposed to emit light downwardly reflected by the reflection wall portion Roughly orthogonal.

在第5發明中，所謂與光的出射方向大致正交，可以是指幾何學上嚴格地正交而不會在透光部中引起光的反射的方向，也可以是指在透光部中幾乎不會引起光的反射的範圍內，與正交偏離少許角度而配設。In the fifth aspect of the invention, the direction perpendicular to the direction in which light is emitted may be a direction that is geometrically strictly orthogonal and does not cause reflection of light in the light transmitting portion, and may be referred to as being in the light transmitting portion. In the range where the reflection of light is hardly caused, it is disposed at a slight angle from the orthogonal direction.

在第5發明中，外罩可由透明的丙烯酸樹脂(acryl resin)或聚碳酸酯樹脂(polycarbonate resin)等的透明合成樹脂、或者透明的玻璃等的具有透光性的材料而形成，但也可由乳白色等的擴散透光性材料來構成。另外，外罩也可不具有對從發光元件發出的光的配光進行控制的功能，並且，此外罩也可形成為至少一部分具有發揮所述配光控制功能的構成。In the fifth aspect of the invention, the outer cover may be formed of a transparent synthetic resin such as a transparent acryl resin or a polycarbonate resin, or a light transmissive material such as transparent glass, but may be made of milky white. It is composed of a diffusing light-transmitting material. Further, the cover may not have a function of controlling the light distribution of the light emitted from the light-emitting element, and the cover may be formed such that at least a part thereof has a configuration that functions as the light distribution control.

在第5發明中，經光源模組的反射面反射等而入射到第1透光部的光，穿過從側方與此反射面相對向的外罩的第1透光部。此時，第1透光部與要穿過它的光的出射方向大致正交，因此，入射到第1透光部的光不易被第1透光部反射而容易穿過第1透光部。同樣地，經上側反射構件反射等而入射到第2透光部的光，穿過從下方與此反射壁部相對向的外罩的第2透光部。此時，第2透光部與要穿過它的光的出射方向大致正交，因此，入射到第2透光部的光不易被第2透光部反射而容易穿過第2透光部。藉此，透光性外罩中的光的損耗(loss)變少，隨之，能夠高效地照射出光。In the fifth aspect of the invention, the light that has entered the first light-transmitting portion due to the reflection of the reflection surface of the light source module passes through the first light-transmitting portion of the outer cover facing the side from the reflection surface. At this time, since the first light transmitting portion is substantially perpendicular to the direction in which the light to be passed through is emitted, the light incident on the first light transmitting portion is less likely to be reflected by the first light transmitting portion and easily passes through the first light transmitting portion. . Similarly, the light that has entered the second light-transmitting portion by reflection or the like by the upper reflection member passes through the second light-transmitting portion of the outer cover that faces the reflection wall portion from below. At this time, since the second light transmitting portion is substantially perpendicular to the direction in which the light to be passed through is emitted, the light incident on the second light transmitting portion is less likely to be reflected by the second light transmitting portion and easily passes through the second light transmitting portion. . Thereby, the loss of light in the translucent cover is reduced, and accordingly, the light can be efficiently emitted.

根據第5發明，第6發明的照明裝置的特徵在於：以所述光源模組的排列方向的鉛垂線為基準的沿著所述光源模組的排列方向的配光特性是，當與所述鉛垂線所成的角度在0°～±50°的範圍內時為全光束，且當與所述鉛垂線所成的角度不足0°～±20°時，光束分配率為50%～60%，當與所述鉛垂線所成的角度為±20°～±50°時，光束分配率為40%～50%。According to a fifth aspect of the invention, in the illumination device of the sixth aspect of the invention, the light distribution characteristic along the arrangement direction of the light source modules based on the vertical line of the light source module arrangement direction is When the angle formed by the plumb line is in the range of 0° to ±50°, it is a full beam, and when the angle formed by the vertical line is less than 0° to ±20°, the beam distribution ratio is 50% to 60%. When the angle formed by the vertical line is ±20° to ±50°, the beam splitting ratio is 40% to 50%.

在第6發明中，在最靠近照明裝置的被照射面即裝置正下方，能照射高光度的點射光(spot light)。借此，可高效地提高裝置正下方的水平面照度。這樣，能夠明亮地對裝置正下方進行照明，隨之，可減少光源的刺眼感，因此，例如當用作防犯燈時，可減小作為眩目感指標的GR值。In the sixth aspect of the invention, a spot light having a high illuminance can be irradiated directly below the device that is the closest to the illumination device. Thereby, the illuminance of the water level directly under the device can be efficiently improved. In this way, it is possible to brightly illuminate the device directly below, and accordingly, the glare of the light source can be reduced. Therefore, for example, when used as a tamper-proof lamp, the GR value which is an indicator of glare can be reduced.

根據第6發明，第7發明的照明裝置的特徵在於：以所述光源模組的排列方向的鉛垂線為基準的沿著與所述光源模組的排列方向正交的方向的配光特性是，當與所述鉛垂線所成的角度不足0°～±20°時，光束分配率為10%～20%，當與所述鉛垂線所成的角度不足±20°～±50°時，光束分配率為35%～45%，當與所述鉛垂線所成的角度不足±50°～±90°時，光束分配率為35%～45%，當與所述鉛垂線所成的角度為±90°～180°時，光束分配率不足5%。According to a ninth aspect of the invention, the illuminating device according to the seventh aspect of the invention is characterized in that the light distribution characteristic in a direction orthogonal to the direction in which the light source modules are arranged is based on a vertical line in the arrangement direction of the light source modules. When the angle formed by the vertical line is less than 0° to ±20°, the beam distribution ratio is 10% to 20%, and when the angle with the vertical line is less than ±20° to ±50°, The beam splitting ratio is 35% to 45%, and when the angle with the vertical line is less than ±50° to ±90°, the beam splitting ratio is 35% to 45%, at an angle to the vertical line. When the temperature is ±90° to 180°, the beam split ratio is less than 5%.

在第7發明中，將光分配到裝置的兩側斜下方，借此，例如可沿著道路的延伸方向來對此道路進行廣範圍的照明，並且，因將光分配到裝置正下方，所以可提高水平面照度。因此，與第6發明中的光的配光特性相配合，能夠明亮地對裝置正下方進行照明，且能減小光源的刺眼感，因此，例如當用作防犯燈時，可使作為眩目感指標的GR值例如小於等於50。而且，由於分配到裝置的上側的光不足5%，因此可抑制光污染。In the seventh invention, light is distributed obliquely downward to both sides of the apparatus, whereby the road can be widely illuminated, for example, along the extending direction of the road, and since the light is distributed directly below the apparatus, Improves horizontal illumination. Therefore, in accordance with the light distribution characteristics of the light in the sixth aspect of the invention, it is possible to brightly illuminate the device directly below and to reduce the glare of the light source, and therefore, for example, when used as a security light, it can be dazzled. The GR value of the sensory index is, for example, 50 or less. Moreover, since light distributed to the upper side of the apparatus is less than 5%, light pollution can be suppressed.

【發明的效果】[Effects of the Invention]

根據第1發明的光源模組，發光元件的排列配設在設置於反射構件的寬度方向中央部的長孔內，因此，發光元件的排列映入到收容著發光元件的排列的反射面的寬度方向兩側部位，借此，視覺上的光源的大小因映入到反射面上的發光元件列的像而變大，能減小光源模組的眩目感。According to the light source module of the first aspect of the invention, since the light-emitting elements are arranged in the long holes provided in the central portion in the width direction of the reflection member, the arrangement of the light-emitting elements is reflected in the width of the reflection surface in which the arrangement of the light-emitting elements is accommodated. By the two sides of the direction, the size of the visual light source is increased by the image of the light-emitting element row reflected on the reflecting surface, and the glare of the light source module can be reduced.

根據第2發明，不僅能確保照明裝置的正下方的亮度，而且還能減少因光向照明裝置的上方漏出而引起的光污染。According to the second aspect of the invention, not only the brightness immediately below the illumination device but also the light pollution caused by the light leaking to the upper side of the illumination device can be reduced.

根據第3發明，在第2發明中，可進一步促進照明裝置的緊湊化，並且也可容易地將由多個光源模組構成的光源視作在與器具本體的發光元件列正交的方向上延伸的一個光源。According to the third aspect of the invention, in the second aspect of the invention, the illuminating device can be further made compact, and the light source including the plurality of light source modules can be easily regarded as extending in a direction orthogonal to the illuminating element row of the luminaire main body. a light source.

A plurality of the wire modules are prepared. In the present embodiment, ten wire modules are prepared.

將反射體14與各線模組組合而構成光源體12。也就是說，如圖5(a)至圖5(c)所示，反射體14是由不銹鋼(stainless steel)或者鋁製的板材所形成，且具有截面大致呈U字形的導水槽狀的反射面14a。此反射體14的延伸方向的上下兩端是開放的。所述構成的線模組是以中心線x-x沿著反射體14的長度方向的中心線y-y的方式，位於並被支撐在反射體14的內側的寬度方向中央部，詳細來說是導水槽的底部。利用螺釘等的固定構件來將各線模組的上下的端部安裝在反射體14的內表面。借此，反射體14的反射面14a左右對稱地位於大致呈線狀的線模組的兩側，從各LED11向兩側放射的照射光被朝向LED的光軸o-o反射。準備多個具有反射體14的光源體12，在本實施形態中，準備10個所述光源體12。各反射體14是將凹陷的內表面加工成鏡面而構成的。The light source body 12 is configured by combining the reflector 14 and each line module. That is, as shown in FIGS. 5(a) to 5(c), the reflector 14 is formed of stainless steel (stainless steel) or aluminum plate material, and has a substantially U-shaped water-sink-like reflection. Face 14a. The upper and lower ends of the extending direction of the reflector 14 are open. The wire module is configured such that the center line xx is located along the center line yy along the longitudinal direction of the reflector 14 and is supported by the center portion in the width direction of the inner side of the reflector 14, in particular, the water guide groove. bottom. The upper and lower ends of the respective wire modules are attached to the inner surface of the reflector 14 by a fixing member such as a screw. Thereby, the reflecting surface 14a of the reflector 14 is symmetrically positioned on both sides of the substantially linear line module, and the irradiation light radiated from the respective LEDs 11 to the both sides is reflected toward the optical axis o-o of the LED. A plurality of light source bodies 12 having the reflectors 14 are prepared. In the present embodiment, ten of the light source bodies 12 are prepared. Each of the reflectors 14 is formed by processing the inner surface of the recess into a mirror surface.

器具本體15是由鋁壓鑄件而製成，且是由一面、具體地說是下表面形成開口部15a的大致呈船底形狀的箱體而構成。在此器具本體15內收容且支撐著安裝板17，此安裝板17上朝著開口部15a而安裝著所述反射體14。也就是說，在器具本體15的一個空間部，圖2中是右方的較大的空間部內，支撐著安裝板17，此安裝板17位於器具本體15的長度方向的中心線z-z上、且由不銹鋼或者鋁製板材構成、截面大致呈V字形。安裝板17是將其棱部17b朝向下方而固定在器具本體15上。The luminaire main body 15 is made of an aluminum die-casting material, and is formed of a substantially hull-shaped casing in which the opening 15a is formed on one surface, specifically, the lower surface. The mounting body 17 is housed and supported in the fixture body 15, and the reflector 14 is attached to the mounting plate 17 toward the opening 15a. That is, in a space portion of the fixture body 15, in the larger space portion on the right in FIG. 2, the mounting plate 17 is supported, and the mounting plate 17 is located on the center line zz in the longitudinal direction of the fixture body 15, and It is made of stainless steel or aluminum plate and has a V-shaped cross section. The mounting plate 17 is fixed to the luminaire main body 15 with its rib 17b facing downward.

安裝板17包括用以配置多個光源體12的一對安裝部，即，包括彼此的背部相對向的一對V字形的兩邊部17c、17c。安裝板17是以兩邊部17c、17c左右對稱地朝器具本體15的底部逐漸展開並傾斜的方式，固定在船底形狀的底部(圖4)。當將器具本體15設置在支柱P(圖6(a)及圖6(b))等上時，所述狀態是V字形的兩邊部17c、17c左右對稱地朝上方逐漸展開並傾斜，V字形的兩邊部17c、17c的板面左右對稱地朝向斜下方。另外，對安裝板17的表面實施鏡面加工，使此薄面具有反射體的功能。The mounting plate 17 includes a pair of mounting portions for arranging a plurality of light source bodies 12, that is, a pair of V-shaped side portions 17c, 17c including opposite back sides of each other. The mounting plate 17 is fixed to the bottom of the shape of the bottom of the ship (Fig. 4) in such a manner that the both side portions 17c, 17c are gradually spread out and inclined toward the bottom of the fixture body 15 in a bilaterally symmetric manner. When the luminaire main body 15 is placed on the support P (Fig. 6 (a) and Fig. 6 (b)) or the like, the two sides 17c, 17c in the V-shaped state are gradually expanded and inclined upward and leftward in a V-shape. The plate faces of the both side portions 17c and 17c are symmetrical obliquely downward. Further, the surface of the mounting board 17 is mirror-finished so that the thin surface has a function of a reflector.

在固定在器具本體15上的安裝板17上，配置並支撐著10個光源體12。也就是說，相對於彼此的背部相對向的V字形的一對邊部17c、17c，各光源體12以大致相等的間隔排列在與LED11的排列方向大致正交的方向上，換而言之，所述各光源體12排列在與光源體12的中心線x-x大致正交的方向上，具體來說，如圖3(a)所示，所述各光源體12排列在安裝板17的長度方向上。Ten light source bodies 12 are disposed and supported on the mounting plate 17 fixed to the fixture body 15. In other words, the light source bodies 12 are arranged at substantially equal intervals in a direction substantially orthogonal to the direction in which the LEDs 11 are arranged, with respect to the pair of side portions 17c and 17c of the V-shape facing each other. The light source bodies 12 are arranged in a direction substantially orthogonal to the center line xx of the light source body 12. Specifically, as shown in FIG. 3(a), the respective light source bodies 12 are arranged at the length of the mounting board 17. In the direction.

詳細來說，10個光源體12中的每5個設置在安裝板17的V字形的左右兩邊部17c、17c上，且以各自相距大致相等的間隔的方式，沿著器具本體15的長度方向而受到固定。例如，利用點焊(spot welding)等的方法來將反射體14的底面部固定到安裝板17上，借此來實施所述固定。這樣，將10個光源體12中的每5個分成一組，且使照射方向大致左右對稱，如圖3(a)所示，從側方觀察器具本體15時，反射體14所構成的導水槽及發光元件11所形成的排列是沿縱向而配設。因此，發光元件11所形成的排列在與反射體12的延伸方向相同的方向上延伸。Specifically, each of the ten light source bodies 12 is disposed on the left and right side portions 17c and 17c of the V-shape of the mounting plate 17, and along the length direction of the luminaire body 15 at substantially equal intervals. And is fixed. For example, the fixing is performed by fixing the bottom surface portion of the reflector 14 to the mounting plate 17 by a method such as spot welding. In this way, each of the ten light source bodies 12 is divided into a group, and the irradiation direction is substantially bilaterally symmetrical. As shown in FIG. 3(a), when the luminaire main body 15 is viewed from the side, the guide body 14 is configured. The arrangement of the water tank and the light-emitting element 11 is arranged in the longitudinal direction. Therefore, the arrangement formed by the light-emitting elements 11 extends in the same direction as the extending direction of the reflector 12.

圖中，17d表示用作上側反射構件的輔助反射體，此輔助反射體是使安裝板17的V字形的兩邊部17c、17c的開放端部向上方延長且大致沿水平方向彎曲而一體地形成。此輔助反射體17d位於覆蓋器具本體15的底面的位置，且配設成與光源體12的上側相對向。借此，使從各LED11向器具本體15的底面側(上側)射出的光，朝器具本體15的開口部15a側反射，即，朝下方反射。另外，對輔助反射體17d的表面實施鏡面加工。In the figure, 17d denotes an auxiliary reflector serving as an upper reflecting member which is formed integrally by extending the open end portions of the V-shaped side portions 17c and 17c of the mounting plate 17 upward and substantially bent in the horizontal direction. . The auxiliary reflector 17d is located at a position covering the bottom surface of the fixture body 15, and is disposed to face the upper side of the light source body 12. Thereby, the light emitted from the respective LEDs 11 toward the bottom surface side (upper side) of the luminaire main body 15 is reflected toward the opening 15a side of the luminaire main body 15, that is, reflected downward. Further, the surface of the auxiliary reflector 17d is mirror-finished.

限光體13對從安裝在光源體12上的各LED11發出的光進行控制，此限光體13是由透明的丙烯酸樹脂等的合成樹脂所構成，且是由在一個面上形成著開口部13a的截面大致呈V字形的箱體所構成，以構成將所述器具本體15的開口部15a加以覆蓋的外罩構件。The light-restricting body 13 controls the light emitted from each of the LEDs 11 mounted on the light source body 12, and the light-restricting body 13 is made of a synthetic resin such as a transparent acrylic resin, and an opening is formed on one surface. The casing 13a has a substantially V-shaped casing, and constitutes a cover member that covers the opening 15a of the luminaire main body 15.

限光體13的內表面上一體地形成著棱鏡(prism)13b。棱鏡13b的棱線在與光源體12的各LED11的排列方向大致正交的方向上連續，換而言之，棱鏡13b的棱線在與光源體12的中心線x-x大致正交的方向上連續(圖3(a))。當將作為外罩構件的限光體13罩住器具本體15，且將器具本體15設置在支柱P等上時，所述棱線位於大致沿著水平方向的方向上。A prism 13b is integrally formed on the inner surface of the light-restricting body 13. The ridgeline of the prism 13b is continuous in a direction substantially orthogonal to the direction in which the LEDs 11 of the light source body 12 are arranged. In other words, the ridgeline of the prism 13b is continuous in a direction substantially orthogonal to the center line xx of the light source body 12. (Fig. 3(a)). When the light-restricting body 13 as the cover member covers the luminaire main body 15 and the ware body 15 is placed on the strut P or the like, the ridge line is located in a direction substantially along the horizontal direction.

棱鏡13b是使指向性比較強的LED11的光折射而獲得作為目的的廣範圍的配光的棱鏡，棱鏡的頂角約形成為90°，此棱鏡13b形成在沿著限光體13的長度方向的兩側面13c、13c和前端面13d上，而且，在截面形狀中，棱鏡連續地形成在兩側面13c、13c和底部13e上，以規定的間隔而形成著多條棱線(或者槽)(圖4)。The prism 13b is a prism that refracts light of the LED 11 having relatively high directivity to obtain a wide range of light distribution. The apex angle of the prism is approximately 90°, and the prism 13b is formed along the length of the light-restricting body 13. On both side faces 13c, 13c and the front end face 13d, and in the cross-sectional shape, prisms are continuously formed on both side faces 13c, 13c and the bottom portion 13e, and a plurality of ridge lines (or grooves) are formed at predetermined intervals ( Figure 4).

使開口部13a與器具本體15的開口部15a相吻合，覆蓋支撐在器具本體15內的光源體12和收容在器具本體15的左方的狹小空間部內的點燈裝置20(圖1、圖2及圖3(a)、圖3(b))，且利用螺釘等以可裝卸的方式來安裝該限光體13。借此，限光體13利用截面大致呈V字形的兩側面13c、13c，在與由大致呈V字形的安裝板17所支撐的各5個光源體12大致平行的狀態下，來覆蓋所述各5個光源體12，而且，以棱鏡13b的棱線位於與LED11的排列方向(光源體12的中心線x-x)大致正交的方向上的方式，來覆蓋所述各5個光源體12(圖3(a))。另外，器具本體15的開口部15a和限光體13的開口部13a是隔著由矽樹脂等所形成的墊片(packing)(未圖示)而嵌合，以保持防水性。可將限光體13上的螺釘卸下來對光源體12及點燈裝置20等進行檢查、修理等。The opening portion 13a is fitted to the opening portion 15a of the luminaire main body 15, and covers the light source body 12 supported in the luminaire main body 15 and the lighting device 20 housed in the narrow space portion on the left side of the luminaire main body 15 (FIG. 1, FIG. 2). 3(a) and 3(b)), the light-restricting body 13 is detachably attached by a screw or the like. Thereby, the light-restricting body 13 covers the above-mentioned five side surface portions 13c and 13c having a substantially V-shaped cross section and is substantially parallel to the five light source bodies 12 supported by the substantially V-shaped mounting plate 17. Each of the five light source bodies 12 and the five light source bodies 12 are covered so that the ridgelines of the prisms 13b are located in a direction substantially orthogonal to the arrangement direction of the LEDs 11 (the center line xx of the light source body 12). Figure 3 (a)). Further, the opening 15a of the luminaire main body 15 and the opening 13a of the light-restricting body 13 are fitted via a packing (not shown) formed of silicone resin or the like to maintain water repellency. The light source body 12, the lighting device 20, and the like can be inspected, repaired, and the like by removing the screws on the light-limiting body 13.

在圖3(b)及圖6(a)中，符號16表示由安裝配件構成的支撐構件，此支撐構件16安裝在器具本體15的一側，即，安裝在點燈裝置20側。利用此支撐構件16及與此支撐構件16組合的安裝帶(mount band)19，來將所述構成的防犯燈10支撐並固定在支柱P等上。In Figs. 3(b) and 6(a), reference numeral 16 denotes a support member composed of a mounting fitting which is attached to one side of the fixture body 15, that is, to the side of the lighting device 20. The support member 16 and the mount band 19 combined with the support member 16 are used to support and fix the constructed compact lamp 10 on the pillar P or the like.

在本實施形態中，以如下的方式來設定防犯燈10的尺寸等。圖3(a)所示的器具本體15的長度尺寸L1約為380mm，包括限光體13的高度尺寸H1約為200mm，圖4所示的寬度尺寸S約為170mm。In the present embodiment, the size and the like of the security light 10 are set as follows. The length L1 of the luminaire main body 15 shown in Fig. 3(a) is about 380 mm, and the height dimension H1 of the light-restricting body 13 is about 200 mm, and the width dimension S shown in Fig. 4 is about 170 mm.

其次，如圖6(a)、圖6(b)所示，將以所述方式構成的防犯燈10安裝在設置干道路A的人行道側的支柱P上並進行使用，對防犯燈10在此情況下的作用進行說明。Next, as shown in Fig. 6 (a) and Fig. 6 (b), the security light 10 configured as described above is attached to the pillar P on the sidewalk side where the dry road A is installed, and is used, and the security light 10 is here. The role in the case will be explained.

首先，如圖6(a)、圖6(b)所示，借由支撐構件16來將器具本體15安裝到支柱P的約4.5m的高度。此時，將器具本體15的中心線z-z設置成大致為水平，以限光體13的棱鏡13b的棱線大致沿著道路的橫切方向的方式來支撐所述器具本體15。借此，由安裝板17的大致呈V字形的兩邊部17c、17c所支撐的每側各5個的各光源體12左右對稱地朝向斜下方。First, as shown in FIGS. 6(a) and 6(b), the fixture body 15 is attached to the height of the pillar P by about 4.5 m by the support member 16. At this time, the center line z-z of the luminaire main body 15 is set to be substantially horizontal, and the ware ridge 15 is supported so that the ridge line of the prism 13b of the light-restricting body 13 substantially follows the transverse direction of the road. Thereby, each of the five light source bodies 12 supported on each side supported by the substantially V-shaped side portions 17c and 17c of the mounting plate 17 is symmetrical obliquely downward.

如果在以所述方式設置的狀態下，將各光源體12的LED11點亮，那麼從各LED11放射出的沿著光軸o-o的照射光會因限光體13的棱鏡13b而折射，左右的照射方向上的光會沿著各光軸方向而大致左右對稱地射向斜下方。同時，不沿著LED11的光軸的從兩側放射出的光在反射體14的兩側的反射面14a上，被反射向光軸方向，經棱鏡13b折射之後，沿著光軸方向左右對稱地射向斜下方(圖5(b))。借此，光從器具本體15的兩側面均勻地射向支柱P的左右(圖6(a)中是射向附圖的近前側與內側)，從而沿著道路A的延伸方向而將人行道側及車行道側的路面照亮，以此進行照明。When the LEDs 11 of the respective light source bodies 12 are turned on in the state set as described above, the illumination light along the optical axis oo emitted from the respective LEDs 11 is refracted by the prisms 13b of the light-restricting body 13, left and right. The light in the irradiation direction is directed obliquely downward in a substantially bilaterally symmetrical manner along the respective optical axis directions. At the same time, light emitted from both sides not along the optical axis of the LED 11 is reflected toward the optical axis direction on the reflecting surface 14a on both sides of the reflector 14, and is refracted along the optical axis direction after being refracted by the prism 13b. The ground is directed obliquely downward (Fig. 5(b)). Thereby, light is uniformly emitted from the both side faces of the luminaire main body 15 to the left and right of the support P (in the front side and the inner side of the drawing in FIG. 6(a)), so that the sidewalk side is along the extending direction of the road A. The road surface on the side of the roadway is illuminated to illuminate.

而且，在不沿著LED11的光軸的光中，射向下方的光經限光體13的底面的棱鏡13b折射而射向下方。射向上方的光被輔助反射體17d向下方反射，並與射向下方的光一同經限光體13的底面的棱鏡13b折射而射向下方，從而將位於所設置的支柱P的大致正下方的下方區域的路面照亮(圖5(c))。根據所述支柱P的大致正下方的照明，光因棱鏡13b而擴散，可利用柔和的光來將支柱P的下方區域照亮，並且可使人在抬頭觀察防犯燈10時不會感到刺眼。Further, among the light that does not follow the optical axis of the LED 11, the light that is directed downward is refracted by the prism 13b on the bottom surface of the light-restricting body 13 and is directed downward. The light that is directed upward is reflected downward by the auxiliary reflector 17d, and is refracted by the prism 13b on the bottom surface of the light-restricting body 13 together with the light that is directed downward, and is directed downward, so as to be located substantially directly below the pillar P provided. The road surface in the lower area is illuminated (Fig. 5(c)). According to the illumination directly below the pillar P, the light is diffused by the prism 13b, and the softer light can be used to illuminate the lower region of the pillar P, and the person can be prevented from being glare when looking up the security light 10 by looking up.

而且，組裝在反射體14中的LED11的排列是配設在反射體14所具有的導水槽狀的反射面14a的內側，且配設在寬度方向中央部，因此，LED11的排列映入到收容著LED11的排列的反射面14a的寬度方向兩側部位。借此，儘管各個LED11較小且亮度高，但防犯燈10在視覺上的光源大小會因映入到反射面14a上的LED11排列的像而變大。也就是說，觀察到配置著比實際用作光源的LED11的數量多的光源，因此，可觀察到較大的使用中的光源。因此，可減小由多個光源體12構成的光源的眩目感。In addition, the arrangement of the LEDs 11 incorporated in the reflector 14 is disposed inside the reflecting surface 14a of the reflecting body 14 and is disposed at the center in the width direction. Therefore, the arrangement of the LEDs 11 is reflected in the housing. The two sides of the reflection surface 14a of the array of the LEDs 11 in the width direction. Thereby, although the respective LEDs 11 are small and have high brightness, the visual light source size of the tamper-resistant lamp 10 becomes large due to the image of the arrangement of the LEDs 11 reflected on the reflecting surface 14a. That is, it was observed that a light source having a larger number of LEDs 11 than actually used as a light source was observed, and therefore, a large light source in use was observed. Therefore, the glare of the light source composed of the plurality of light source bodies 12 can be reduced.

在此情況下，各LED11與它們所映入的反射體14的寬度方向的兩側部位之間的距離相等，因此，反射面14a對於排成列的各個LED11的反射控制是相同的。因此，能夠進行覆蓋廣範圍的照明，也就是說，可利用反射面14a來使光擴散到道路的整個橫向範圍，並在道路的延伸方向上一直到達遠處，從而可對道路的規定長度的範圍進行照明。In this case, since the distance between each of the LEDs 11 and the both sides in the width direction of the reflector 14 reflected by them is equal, the reflection control of the reflection surface 14a for each of the LEDs 11 arranged in a row is the same. Therefore, it is possible to cover a wide range of illumination, that is, the reflective surface 14a can be used to diffuse the light to the entire lateral extent of the road, and to reach the far side in the direction in which the road extends, so that the prescribed length of the road can be The range is illuminated.

根據所述作用，如圖6(b)所示意地表示的配光狀態那樣，防犯燈10的照明能夠實現廣範圍的配光，即，從支柱P的下方區域沿著人行道側及車行道側的道路A的延伸方向進行照射。According to the action, as in the light distribution state schematically shown in FIG. 6(b), the illumination of the security light 10 can realize a wide range of light distribution, that is, from the lower region of the pillar P along the sidewalk side and the roadway. The direction of extension of the side road A is irradiated.

以上，根據本實施形態，多個LED11構成為沿著光源體12的中心線x-x而大致直線狀地排列形成且被安裝的線模組，因此，構造得到簡化且組裝作業也變得簡單。同時，指向性比較強的LED11的照射光，經過棱線在與LED11的排列方向大致正交的方向上連續形成的棱鏡13b後產生折射，從而可獲得廣範圍的配光，因此，無須如先前那樣使用多個昂貴的LED，便可獲得廣範圍的配光。借此，也能解決成本方面的問題。As described above, according to the present embodiment, the plurality of LEDs 11 are configured as line modules that are arranged substantially linearly along the center line x-x of the light source body 12, so that the structure is simplified and the assembly work is simplified. At the same time, the illuminating light of the LED 11 having a relatively high directivity is refracted by the prism 13b continuously formed in the direction substantially orthogonal to the direction in which the LEDs 11 are arranged, so that a wide range of light distribution can be obtained, and therefore, it is not necessary to In this way, a wide range of light distribution can be obtained by using a plurality of expensive LEDs. In this way, it is also possible to solve the cost problem.

另外，光源體12是由線模組而構成，因此，可根據需要以選擇適當數量的光源體12，來進行配光特性適合於防犯燈10的設置場所的照明。例如，當在僅需單側照明的道路盡頭，省略左右對稱地設置的光源體中的單側的光源體，或者將其設為不點燈狀態，從而可阻止光射向無需照明的方向，以免對附近住宅或農田裏的農作物造成不良影響，而且可提供適用於各種設置場所的通用性良好的防犯燈。另外，也可在點燈裝置20內設置調光控制裝置，以此來對多個光源體12進行適當選擇而使其點燈或者滅燈，而與道路周邊的建築物或環境等設置場所的狀況相應地進行防犯照明。Further, since the light source body 12 is constituted by a wire module, it is possible to select an appropriate number of the light source bodies 12 as needed to perform illumination with a light distribution characteristic suitable for the installation place of the lamp 10 . For example, when the end of the road requiring only one-side illumination is omitted, the one-side light source body in the left-right symmetrically disposed light source body is omitted, or it is set to be unlit, thereby preventing light from being directed to a direction in which illumination is not required. In order to avoid adverse effects on crops in nearby houses or farmland, it is also possible to provide a versatile tamper-proof lamp suitable for various installation places. Further, a dimming control device may be provided in the lighting device 20, whereby the plurality of light source bodies 12 may be appropriately selected to be turned on or off, and installed in a place such as a building or an environment around the road. The situation is correspondingly protected against illumination.

光源體12的LED11構成為將由藍色LED芯片及由此藍色LED芯片激發的黃色熒光體而發出白色光的高亮度、高輸出的多個表面安裝型LED排列在模組基板11a上而成的具有通用性的線模組，此時可獲得能由棱鏡來控制照射光的配光，因此，無須如專利文獻1所述對各個炮彈形的LED的配光進行控制，所以在成本方面有利。The LEDs 11 of the light source body 12 are configured by arranging a plurality of high-brightness, high-output surface-mount LEDs that emit white light by a blue LED chip and a yellow phosphor excited by the blue LED chip on the module substrate 11a. A versatile wire module, in which a light distribution capable of controlling the illuminating light by the prism is obtained, so that it is not necessary to control the light distribution of the respective bullet-shaped LEDs as described in Patent Document 1, so that it is advantageous in terms of cost. .

因光源體12中安裝了反射體14，因此，可使從各LED11漏到側方的光向光軸方向反射，從而可有效活用這些光，從而可進行配光更廣範圍的照明。進而，添設輔助反射體17d，使支撐光源體12的安裝板17發揮反射體的功能，因此，從LED11漏射的光受到此安裝板17的反射，而減少了浪費的光，從而得到更有效的活用。Since the reflector 14 is attached to the light source body 12, the light leaking from the respective LEDs 11 to the side can be reflected in the optical axis direction, and the light can be effectively utilized, and illumination of a wider range of light distribution can be performed. Further, the auxiliary reflector 17d is added to cause the mounting plate 17 supporting the light source body 12 to function as a reflector. Therefore, the light leaked from the LED 11 is reflected by the mounting plate 17, and the wasted light is reduced, thereby obtaining more Effective use.

而且，因將半導體發光元件即LED11用作光源，因此使用壽命變長，無須承擔燈泡更換等的維護費，可長期使用。同時，利用LED11和棱鏡13b的組合，能以廣範圍的配光來進行照明，且可擴大防犯燈10的設置間隔，從而能以低成本來獲得廣範圍的照明。Further, since the LED 11 which is a semiconductor light-emitting element is used as a light source, the service life is long, and maintenance costs such as replacement of a bulb are not required, and it can be used for a long period of time. At the same time, by using a combination of the LED 11 and the prism 13b, illumination can be performed with a wide range of light distribution, and the installation interval of the security light 10 can be expanded, so that a wide range of illumination can be obtained at low cost.

而且，因將LED11用作光源，因此，無需常規的熒光燈或HID燈的點燈裝置中的較重的穩定器(stabilizer)等構件，因此可使防犯燈10整體變得較小且較輕，當將防犯燈10設置在支柱P等高處時的施工性也變得容易，且能夠切實地設置。Moreover, since the LED 11 is used as a light source, a member such as a heavy fluorescent lamp or a heavy stabilizer in a lighting device of the HID lamp is not required, so that the entire lamp 10 can be made smaller and lighter. When the security light 10 is placed at the height of the pillar P, the workability is also easy, and it can be reliably provided.

多個光源體12分別配置在大致呈V字形的安裝板17的各自的背部相對向的V字形的一對邊部17c、17c，因此，可切實地進行配光控制，以使各LED11的照射光的照射方向大致對稱。Since the plurality of light source bodies 12 are respectively disposed on the V-shaped pair of side portions 17c and 17c facing the respective back sides of the substantially V-shaped mounting plates 17, the light distribution control can be reliably performed to illuminate the respective LEDs 11 The direction of illumination of the light is substantially symmetrical.

多個光源體12，由大致呈V字形的安裝板17支撐，且一併收容在器具本體15內的一方的較大空間部內，而器具本體15內的另一方的狹小空間部內收容點燈裝置20，因此，能提供一種零件配置也得到簡化的易組裝的防犯燈。The plurality of light source bodies 12 are supported by a substantially V-shaped mounting plate 17, and are housed in one of the larger space portions in the fixture body 15, and the other narrow space portion in the fixture body 15 houses the lighting device. 20, therefore, it is possible to provide an easy-to-assemble security light with a simplified component configuration.

以上，本實施形態中，限光體13的棱鏡13b的頂角約形成為90°，但根據棱鏡13b與光源體12的位置關係，可選擇適當的頂角角度等，以獲得更接近預期值的廣範圍的配光。而且，棱鏡13b是形成在限光體13的長度方向上的整個面上，但也可如圖7(a)所示，僅形成在與光源體12對應的部分。此時，未形成棱鏡的部分則成為透明狀態、或者經光擴散處理的半透明狀態。As described above, in the present embodiment, the apex angle of the prism 13b of the light-restricting member 13 is approximately 90°. However, depending on the positional relationship between the prism 13b and the light source body 12, an appropriate apex angle or the like can be selected to obtain a closer value to the expected value. A wide range of light distribution. Further, the prism 13b is formed on the entire surface in the longitudinal direction of the light-restricting body 13, but may be formed only in a portion corresponding to the light source body 12 as shown in Fig. 7(a). At this time, the portion where the prism is not formed is in a transparent state or a translucent state subjected to light diffusion treatment.

另外，從截面形狀看，棱鏡13b是連續形成的，但也可如圖7(b)所示，與光源體12對應的部分由透明體構成，而僅在下方及上端部分形成棱鏡13b。這樣，與光源體12對應的側面部分成為透明的，因此，使得指向性較強的LED11的光從透明部分直接射出，而到達更遠處。另外，在有支柱P的防犯燈的正下方的下方部分，光經過棱鏡13b產生擴散後變得柔和，從而可以柔和的光來照射支柱P的下方區域，而且，可抑制人仰視防犯燈10時產生的刺眼感。另外，利用上端部分的棱鏡13b，可選擇適當的頂角角度等進行設定，從而阻止光從器具本體15向上方照射。這樣，不會對附近住宅或農田裏的農作物造成不良影響。Further, the prism 13b is formed continuously from the cross-sectional shape. However, as shown in Fig. 7(b), the portion corresponding to the light source body 12 may be formed of a transparent body, and the prism 13b may be formed only at the lower and upper end portions. Thus, the side surface portion corresponding to the light source body 12 becomes transparent, and therefore, the light of the LED 11 having high directivity is directly emitted from the transparent portion to reach further. Further, in the lower portion directly under the tamper-proof lamp having the pillar P, the light is diffused by the prism 13b and softened, so that the lower region of the pillar P can be irradiated with soft light, and the person can be suppressed from looking up at the tamper-proof lamp 10 The sensation of glare. Further, the prism 13b at the upper end portion can be set by selecting an appropriate apex angle or the like to prevent the light from being irradiated upward from the luminaire main body 15. This will not adversely affect crops in nearby homes or farms.

而且，也可如圖7(c)所示，當防犯燈10的下方區域的照度不足時，不形成下方的棱鏡而成為透明或者半透明狀態，來照亮防犯燈10的下方區域的路面。Further, as shown in FIG. 7(c), when the illuminance in the lower region of the tamper-proof lamp 10 is insufficient, the lower prism is not formed and is in a transparent or semi-transparent state to illuminate the road surface in the lower region of the tamper-proof lamp 10.

也可使安裝在光源體12上的反射體14的配置角度可變，從而可調整配光。而且，也可如圖8(a)所示，安裝著反射體14的光源體12可相對於安裝板17旋轉，角度、也就是說呈線狀排列的LED11的排列方向與棱鏡13b的棱線所成的角度可變，從而可進一步調整配光。利用所述反射體14及光源體12的調整功能，可獲得例如適合於彎曲道路、或拐角的配光。It is also possible to change the arrangement angle of the reflector 14 mounted on the light source body 12 so that the light distribution can be adjusted. Further, as shown in Fig. 8(a), the light source body 12 to which the reflector 14 is attached may be rotated with respect to the mounting plate 17, and the angle, that is, the arrangement direction of the LEDs 11 arranged in a line and the ridge line of the prism 13b. The resulting angle is variable so that the light distribution can be further adjusted. With the adjustment function of the reflector 14 and the light source body 12, for example, a light distribution suitable for a curved road or a corner can be obtained.

反射體14是由安裝板17及輔助反射體17d經鏡面加工而構成，但當這些構件是由不銹鋼或鋁等構成時，也可不特意進行鏡面加工。反射體14也可由聚對苯二甲基丁二酯(polybutylene terphthalate，PBT)等的白色合成樹脂構成。而且，也可由所述金屬或合成樹脂上經鏡面或者半鏡面加工等而形成。The reflector 14 is formed by mirror-finishing the mounting plate 17 and the auxiliary reflector 17d. However, when these members are made of stainless steel or aluminum, the mirror surface processing may not be performed. The reflector 14 may be made of a white synthetic resin such as polybutylene terphthalate (PBT). Further, it may be formed by mirror or semi-specular processing or the like on the metal or synthetic resin.

反射體14對應于所有光源體12而設，但也可為了獲得預期的配光而僅與一部分光源體相對應地設置。反射體14可與器具本體15或者支撐光源體12的構件等形成為一體，或者也可單獨形成。而且，多個反射體14是由相同材料構成且具有相同的反射性能，但也可由其他材料構成，而且，各自的反射性能可互不相同或者一部分的反射性能互不相同。另外，各個反射體14可形成為一體，也可單獨地與各個光源體分別對應地形成。The reflector 14 is provided corresponding to all of the light source bodies 12, but may be provided only corresponding to a part of the light source bodies in order to obtain a desired light distribution. The reflector 14 may be integrally formed with the fixture body 15 or a member that supports the light source body 12, or may be formed separately. Further, the plurality of reflectors 14 are made of the same material and have the same reflection performance, but may be composed of other materials, and the respective reflection properties may be different from each other or a part of the reflection properties may be different from each other. Further, each of the reflectors 14 may be formed integrally, or may be formed separately corresponding to each of the light source bodies.

收容在器具本體15內的點燈裝置20，也可不設在器具本體15內。器具本體15與作為外罩構件的限光體13之間是利用螺釘來固定的，但也可對器具本體15和限光體13的一端邊緣部以可自由旋轉的方式進行軸支，且可將此軸作為支點而開閉。雖限光體13具有器具本體15的外罩構件的功能，但如圖8(b)所示，外罩構件30是由框狀構件構成的，此框狀構件包括覆蓋點燈裝置20的部分30a和與光源體12相對向的開口部30b，且有限光體13′嵌在此框狀構件的開口部30b中，限光體13僅具有專門控制光的功能。The lighting device 20 housed in the luminaire main body 15 may not be provided in the luminaire main body 15. The luminaire body 15 and the light-limiting body 13 as the cover member are fixed by screws, but the luminaire body 15 and the one end edge portion of the light-restricting body 13 may be pivoted in a freely rotatable manner, and This shaft opens and closes as a fulcrum. Although the light-limiting body 13 has the function of the cover member of the fixture body 15, as shown in FIG. 8(b), the cover member 30 is constituted by a frame-shaped member including a portion 30a covering the lighting device 20 and The opening portion 30b opposed to the light source body 12, and the finite light body 13' is embedded in the opening portion 30b of the frame member, and the light-limiting body 13 has only a function of specifically controlling light.

發光元件是由作為半導體發光元件的LED11構成，除此以外，也可由冷陰極燈(cold cathode lamp)、鹵素燈(halogen lamp)、電致發光(electroluminescence，EL)元件等構成。The light-emitting element is composed of an LED 11 as a semiconductor light-emitting element, and may be composed of a cold cathode lamp, a halogen lamp, an electroluminescence (EL) element, or the like.

利用支撐構件16來支撐防犯燈10，使得限光體13的棱鏡13b大致沿著道路的橫切方向，但棱鏡無須在幾何學上嚴格地位於道路橫切方向，可根據設置現場的狀況，而支撐在與道路橫切方向偏離少許角度的位置上。The support member 16 is used to support the tamper-proof lamp 10 such that the prism 13b of the light-limiting body 13 is substantially along the transverse direction of the road, but the prism does not need to be geometrically strictly located in the cross-sectional direction of the road, depending on the condition of the installation site. The support is at a position that is slightly offset from the direction of the road.

第1實施形態中，構成的是室外用防犯燈，但也可構成研究設施、圖書館或美術館等的走廊中使用的，沿著走廊的延伸方向進行照明的室內用照明器具。當構成室內用照明器具時，也可省略用於防水的墊片。In the first embodiment, the outdoor tamper-proof lamp is configured, but it may be used as an indoor lighting device that is used in a corridor of a research facility, a library, an art museum, or the like, and that illuminates along the direction in which the corridor extends. When constituting an indoor lighting fixture, the gasket for waterproofing may be omitted.

第1實施形態中的防犯燈10包括：多個光源體12，沿著與此發光元件11的排列方向大致正交的方向而配設，且有多個發光元件11大致呈線狀排列在所述光源體12上；限光體13，以棱線在與此光源體12的發光元件11的排列方向大致正交的方向上為連續的方式形成著棱鏡13b，對發光元件11的照射光進行配光控制；以及器具本體15，支撐光源體12和限光體13。因此，利用如上所述沿著與此發光元件11的排列方向大致正交的方向而配設、且有多個發光元件11大致呈線狀排列形成在其上的多個光源體12，可簡化發光元件11的排列，而且，利用以使棱線在與光源體12的發光元件11的排列方向大致正交的方向上連續的方式而形成棱鏡13b、對發光元件11的照射光進行配光控制的限光體13，可進行廣範圍的照明。The security light 10 of the first embodiment includes a plurality of light source bodies 12 disposed along a direction substantially orthogonal to the direction in which the light emitting elements 11 are arranged, and a plurality of light emitting elements 11 are arranged substantially in a line shape. In the light source body 12, the light-receiving body 13 is formed such that the prism 13b is continuous with the ridge line in a direction substantially orthogonal to the direction in which the light-emitting elements 11 of the light source body 12 are arranged, and the irradiation light of the light-emitting element 11 is performed. The light distribution control; and the fixture body 15 support the light source body 12 and the light limiting body 13. Therefore, it is possible to simplify the plurality of light source bodies 12 which are disposed in a direction substantially orthogonal to the arrangement direction of the light-emitting elements 11 as described above and in which a plurality of light-emitting elements 11 are arranged substantially in a line shape. The arrangement of the light-emitting elements 11 is such that the prisms 13b are formed so that the ridge lines are continuous in a direction substantially orthogonal to the direction in which the light-emitting elements 11 of the light source body 12 are arranged, and the light distribution of the light-emitting elements 11 is controlled. The light-limiting body 13 can perform a wide range of illumination.

另外，第1實施形態中的防犯燈10中，多個光源體12以照射方向大致對稱的方式，而分別配置在各自的背部相對向的一對邊部(安裝部)15c、15c上。這樣，可切實地對發光元件11的照射光進行配光控制，從而進行廣範圍的照明。In the tamper-resistant lamp 10 of the first embodiment, the plurality of light source bodies 12 are disposed on the pair of side portions (mounting portions) 15c and 15c whose respective back faces are opposed to each other so as to be substantially symmetrical in the irradiation direction. In this way, it is possible to reliably perform light distribution control of the illumination light of the light-emitting element 11 to perform illumination in a wide range.

防犯燈等的照明裝置中，為了能擴大設置間隔來進行照明，以達到節能或節省施工步驟的目的，要求配光沿著道路方向在長度方向上擴大。然而，當如上所述在長度方向上擴大照射距離時，若將照明裝置設置在例如拐角、彎曲道路等處，那麼單側的照射光較充分，而產生漏光，可能會對附近住宅或農田裏的農作物造成不良影響。In an illuminating device such as a tamper-proof lamp, in order to increase the installation interval and perform illumination, it is required to achieve energy saving or a construction-saving step, and it is required to expand the light distribution in the longitudinal direction along the road direction. However, when the irradiation distance is enlarged in the longitudinal direction as described above, if the illuminating device is disposed at, for example, a corner, a curved road, or the like, the illuminating light of one side is sufficient, and light leakage occurs, which may be in a nearby house or farmland. The crops cause adverse effects.

第2實施形態的目的在於解決所述問題，其目的在於提供一種能對拐角、彎曲道路等高效地進行照明，且能將漏光達到最小限度的照明裝置。The second embodiment aims to solve the above problems, and an object of the invention is to provide an illumination device capable of efficiently lighting corners, curved roads, and the like, and minimizing light leakage.

以下，參照圖9(a)、圖9(b)以及圖10(a)至10(e)，對此照明裝置進行說明。另外，圖9(a)、圖9(b)以及圖10(a)至10(e)中，對於與第1實施形態中的圖1、圖2、圖3(a)、圖3(b)、圖4、圖5(a)至圖5(c)、圖6(a)、圖6(b)、圖7(a)至圖7(c)以及圖8(a)、圖8(b)中相同的部分，使用相同的符號，並省略相關的詳細說明。Hereinafter, the illumination device will be described with reference to FIGS. 9(a), 9(b) and 10(a) to 10(e). 9(a), 9(b), and 10(a) to 10(e), Fig. 1, Fig. 2, Fig. 3(a), and Fig. 3(b) in the first embodiment. ), Fig. 4, Fig. 5(a) to Fig. 5(c), Fig. 6(a), Fig. 6(b), Fig. 7(a) to Fig. 7(c), and Fig. 8(a), Fig. 8( The same parts in b) are given the same symbols, and the detailed description is omitted.

根據第1實施形態中的防犯燈10，第2實施形態中的照明裝置即防犯燈中，以器具本體的中心線z-z為分別而劃分成兩部分，從而形成右側用防犯燈R和左側用防犯燈L。這樣，右側用防犯燈R中，器具本體15內組裝著5個光源體12和限光體13，此5個光源體12支撐在安裝板17的右側，此限光體13中以棱線沿著與此光源體的各LED11的排列方向大致正交的方向以連續的方式而形成著棱鏡13b。同樣，左側用防犯燈L中，器具本體15內組裝著5個光源體12和限光體13，此5個光源體12支撐在安裝板17的左側，此限光體13中以棱線沿著與此光源體的各LED11的排列方向大致正交的方向以連續的方式而形成著棱鏡13b。According to the tamper-proof lamp 10 of the first embodiment, the tamper lamp of the illuminating device according to the second embodiment is divided into two parts by the center line zz of the luminaire main body, thereby forming the right-hand tamper-proof lamp R and the left-side tamper-proof lamp. Light L. Thus, in the right-hand anti-discrimination lamp R, five light source bodies 12 and a light-restricting body 13 are assembled in the apparatus body 15, and the five light-source bodies 12 are supported on the right side of the mounting board 17, and the light-limiting body 13 is ridged along the edge The prism 13b is formed in a continuous manner in a direction substantially orthogonal to the arrangement direction of the LEDs 11 of the light source body. Similarly, in the left-hand security light L, five light source bodies 12 and a light-limiting body 13 are assembled in the apparatus body 15, and the five light source bodies 12 are supported on the left side of the mounting board 17, and the light-limiting body 13 is ridged along the edge. The prism 13b is formed in a continuous manner in a direction substantially orthogonal to the arrangement direction of the LEDs 11 of the light source body.

另外，在成為左右分割面的器具本體的側面上，利用鋁壓鑄件(die cast)而分別一體形成側板40、40，且在此側板40、40與作為外罩構件的限光體13之間設置墊片(packing)，從而具有防水功能。Further, the side plates 40 and 40 are integrally formed by the aluminum die-casting on the side surface of the instrument body which is the left and right divided faces, and the side plates 40 and 40 are disposed between the side plates 40 and 40 and the light-limiting body 13 as the cover member. Packing to provide waterproofing.

以所述方式構成的右側用防犯燈R，當將支撐在一側的各光源體12的LED11點亮時，與第1實施形態中相同，從各LED11射出的光受到限光體13的棱鏡13b的控制，而向器具本體15的單面、圖9(a)中為右側射出。而且，左側用防犯燈L中，與第1實施形態中相同，從各LED11射出的光受到限光體13的棱鏡13b的控制，而向器具本體15的單面、圖9(b)中為左側射出。另外，支撐構件16可相對于支柱P而旋轉，從而可將器具本體15設置在任意方向。When the LED 11 for each of the light source bodies 12 supported on one side is turned on, the light emitted from each of the LEDs 11 receives the prism of the light-restricting body 13 as in the first embodiment. The control of 13b is emitted to one side of the luminaire main body 15 and to the right side in Fig. 9(a). Further, in the left-side tamper-proof lamp L, as in the first embodiment, the light emitted from each of the LEDs 11 is controlled by the prism 13b of the light-restricting body 13, and is directed to one side of the luminaire main body 15 and in FIG. 9(b). Shot on the left side. In addition, the support member 16 is rotatable relative to the strut P so that the fixture body 15 can be placed in any direction.

以所述方式構成的右側用防犯燈R和左側用防犯燈L以如下方式設置在各種道路上。也就是說，如圖10(a)所示，在直線狀的道路A上，在1根支柱P上設置右側用防犯燈R和左側用防犯燈L共計2台防犯燈時，以設在其分割面上的側板40相對向的方式，換而言之是以限光體13面向左右延伸的道路的方式，來設置支柱P。這樣，與第1實施形態中相同，設置成限光體13的棱鏡13b的棱線大致沿著道路的橫切方向，且如圖10(a)中示意地表示的配光狀態所示，防犯燈的照明能夠實現廣範圍配光，即，從支柱P的下方區域沿著左右的人行道側及車行道側的道路A的延伸方向進行照射。此時，為了使光不會洩漏到道路以外的區域，而利用棱鏡13b來控制來自各LED11的光。The right-hand tamper-proof lamp R and the left-side tamper-proof lamp L configured in the above-described manner are disposed on various roads in the following manner. In other words, as shown in Fig. 10 (a), when the right-side tamper-proof lamp R and the left-side tamper-proof lamp L are provided in a single line P on the straight road A, a total of two tamper lights are provided. The support P is provided in such a manner that the side plates 40 on the split surface face each other, in other words, the road in which the light-limiting body 13 faces the left and right. As described above, in the same manner as in the first embodiment, the ridge line of the prism 13b provided as the light-restricting member 13 is substantially along the transverse direction of the road, and as shown in the light distribution state schematically shown in Fig. 10(a), The illumination of the lamp enables wide-area light distribution, that is, irradiation from the lower region of the pillar P along the left and right sidewalk side and the direction of the road A on the sidewalk side. At this time, in order to prevent light from leaking to an area other than the road, the light from each of the LEDs 11 is controlled by the prism 13b.

如圖10(b)所示，在彎曲道路A上，在1根支柱P上設置右側用防犯燈R和左側用防犯燈L這兩台防犯燈，右側用防犯燈R為了能沿著右側彎曲路面照射，而以規定的角度朝向右側而設置在支柱P上。左側用防犯燈L為了能沿著左側彎曲路面照射，而以規定的角度朝向左側而設置在支柱P上。這樣，利用右側用防犯燈R，能夠以從支柱P的下方區域沿著向右側彎曲的人行道側及車行道側的道路A的延伸方向進行照射的廣範圍配光而進行照明。而且，利用左側用防犯燈L，能夠以從支柱P的下方區域沿著向左側彎曲的人行道側及車行道側的道路A的延伸方向進行照射的廣範圍配光而進行照明。這樣，如圖10(b)中示意地表示的配光狀態所示，利用左右的防犯燈R、L，能夠以沿著曲線的廣範圍配光來進行照明。同時，不會產生如圖10(b)中的虛線所示的漏光，從而不會給附近住宅或農田裏的農作物造成不良影響。As shown in Fig. 10 (b), on the curved road A, two anti-discrimination lamps R for the right side and the anti-discrimination lamp L for the left side are provided on one of the pillars P, and the anti-discrimination lamp R for the right side is bent along the right side. The road surface is irradiated and placed on the pillar P at a predetermined angle toward the right side. The left-side tamper-proof lamp L is provided on the pillar P at a predetermined angle toward the left side so as to be able to illuminate the road surface along the left side. In this way, the right-side tamper-proof lamp R can be used to illuminate a wide-range light distribution that is irradiated from the lower region of the pillar P along the sidewalk side and the roadway side road A that is curved to the right side. In addition, the left-side tamper-proof lamp L can illuminate a wide-area light distribution that is irradiated from the lower region of the pillar P along the sidewalk side and the roadway side road A that is curved to the left side. As described above, as shown in the light distribution state schematically shown in FIG. 10(b), the left and right security lights R and L can be used to illuminate with a wide range of light along the curved line. At the same time, light leakage as shown by the broken line in Fig. 10(b) is not generated, so that it does not adversely affect crops in nearby houses or farmland.

在拐角的道路A上，如圖10(c)所示，在1根支柱P上設置右側用防犯燈R和左側用防犯燈L這兩台防犯燈時，為了能沿著彎曲的道路進行照射，而相隔約90°進行配置。也就是說，右側用防犯燈R為了能沿著向右彎曲的路面進行照射，而朝向右側設置在支柱P上。左側用防犯燈L為了能沿著向左彎曲的路面進行照射，而朝向左側設置在支柱P。這樣，利用右側用防犯燈R，能夠以從支柱P的下方區域沿著向右側彎曲的人行道側及車行道側的道路A的延伸方向而進行照射的廣範圍配光來進行照明。而且，利用左側用防犯燈L，能夠以從支柱P的下方區域沿著向左側彎曲的人行道側及車行道側的道路A的延伸方向而進行照射的廣範圍配光來進行照明。這樣，如圖10(c)中示意地表示的配光狀態所示，利用左右的防犯燈R、L，能夠以沿著拐角道路A進行照射的廣範圍配光而進行照明。同時，不會產生圖10(d)中的虛線所示的常規的設置形態下會產生的漏光，從而不會對拐角處的住宅或農田裏的農作物造成不良影響。圖中10'表示常規的防犯燈。In the road A on the corner, as shown in Fig. 10(c), when the two anti-offer lights R and the left-side anti-discrimination lamp L are provided on one of the pillars P, in order to be able to illuminate along a curved road. And configured at about 90° apart. That is to say, the right-side tamper-proof lamp R is disposed on the pillar P toward the right side in order to be irradiated along the road surface curved to the right. The left-side tamper-proof lamp L is provided on the left side toward the left side so as to be able to illuminate along the road surface curved to the left. In this way, the right-side tamper-resistant lamp R can be used to illuminate a wide-range light distribution that is irradiated from the lower region of the pillar P along the sidewalk side and the roadway side road A that is curved to the right side. In addition, the left-side tamper-proof lamp L can illuminate with a wide-range light distribution that is irradiated from the lower region of the pillar P along the sidewalk side and the roadway side road A that is curved to the left side. As described above, as shown in the light distribution state schematically shown in FIG. 10( c ), the left and right security lights R and L can be used to illuminate with a wide range of light distribution that is irradiated along the corner road A. At the same time, light leakage which is generated in the conventional arrangement form shown by the broken line in Fig. 10(d) is not generated, so that the crops in the house or the farmland at the corners are not adversely affected. 10' in the figure indicates a conventional security light.

其次，在處於盡頭的道路A上，如圖10(e)所示，設置一台左側用防犯燈L，使設在其分割面上的側板40朝向路的盡頭，換而言之是使限光體13朝向延伸的道路A而設置在支柱P上。這樣，與第1實施形態中相同，設置成限光體13的棱鏡13b的棱線大致沿著道路橫切方向，如圖10(e)中示意地表示的配光狀態所示，能夠以從支柱P的下方區域沿著人行道側及車行道側的道路A的延伸方向進行照射的廣範圍配光而進行照明。同時，不會產生虛線所示的漏光，從而不會對道路盡頭那一側的住宅或農田裏的農作物造成不良影響。另外，與圖10(e)相反，當在道路盡頭的左側設置支柱且安裝防犯燈時，使用一台右側用防犯燈R，使其限光體13朝向延伸的道路A而設置在支柱P上，這樣，可獲得與圖10(e)相同的作用效果。Next, at the end of the road A, as shown in Fig. 10(e), a left-side tamper-proof lamp L is provided so that the side plate 40 provided on the divided surface faces the end of the road, in other words, the limit The light body 13 is disposed on the pillar P toward the extended road A. As described above, in the same manner as in the first embodiment, the ridge line of the prism 13b provided as the light-restricting member 13 is substantially along the transverse direction of the road, as shown in the light distribution state schematically shown in Fig. 10(e). The lower region of the pillar P is illuminated along a wide range of light distribution that is irradiated on the sidewalk side and the roadway side of the roadway side. At the same time, there will be no light leakage as indicated by the dotted line, so that it will not adversely affect the crops in the house or farmland on the side of the road. Further, in contrast to FIG. 10(e), when a pillar is provided on the left side of the end of the road and a security light is attached, a right-purpose light-preventing lamp R is used, and the light-restricting body 13 is disposed on the pillar P toward the extended road A. Thus, the same operational effects as those of Fig. 10(e) can be obtained.

以上，根據第2實施形態，可提供一種能對拐角、彎曲、盡頭等的道路A高效地進行照明、且可使漏光達到最小限度、而且適合於各種設置場所的條件的通用性良好的作為照明裝置的防犯燈。As described above, according to the second embodiment, it is possible to provide illumination that can efficiently illuminate the road A such as corners, bends, and end, and minimizes light leakage, and is suitable for various installation places. The guard light of the device.

而且，根據第2實施形態中的防犯燈，可僅在一側進行配光，因此，可減少光源體12的LED11的數量，從而可降低價格，反射體14或限光體13等光學系統都減半，從而可使器具變得較小且較輕，而且對支柱的設置作業也變得簡單。Further, according to the tamper-proof lamp of the second embodiment, the light distribution can be performed only on one side, so that the number of the LEDs 11 of the light source body 12 can be reduced, and the price can be reduced, and the optical system such as the reflector 14 or the light-restricting body 13 can be reduced. Halving, which makes the appliance smaller and lighter, and the installation of the pillars is also simple.

第2實施形態中，使用棱鏡作為限光體，但也可使用凸透鏡(converging lens)等透鏡體。此時，作為光學系統零件，可由光源體及透鏡體，或者光源體、反射體及透鏡體構成。In the second embodiment, a prism is used as the light-limiting body, but a lens body such as a convex lens may be used. In this case, the optical system component may be composed of a light source body and a lens body, or a light source body, a reflector, and a lens body.

另外，第2實施形態中的其他結構、作業、作用效果、變形例等都與第1實施形態相同。The other configurations, operations, operational effects, modifications, and the like in the second embodiment are the same as those in the first embodiment.

參照圖11至圖14、圖15(A)、圖15(B)、圖16、圖17(A)、圖17(B)、圖18(A)至圖18(D)、圖19(A)、圖19(B)以及圖20，對本發明的第3實施形態進行說明。另外，圖11至圖14、圖15(A)、圖15(B)、圖16、圖17(A)、圖17(B)、圖18(A)至圖18(D)、圖19(A)、圖19(B)中，對於與第1實施形態中的圖1、圖2、圖3(a)、圖3(b)、圖4、圖5(a)至圖5(c)、圖6(a)、圖6(b)、圖7(a)至圖7(c)以及圖8(a)、圖8(b)中相同的部分，使用相同的符號，並省略相關的詳細說明。11 to 14, 15 (A), 15 (B), 16, 17, (A), 17 (B), 18 (A) to 18 (D), and 19 (A) Fig. 19 (B) and Fig. 20 show a third embodiment of the present invention. 11 to 14, FIG. 15 (A), FIG. 15 (B), FIG. 16, FIG. 17 (A), FIG. 17 (B), FIG. 18 (A) to FIG. 18 (D), FIG. 19 ( A) and FIG. 19(B), FIG. 1, FIG. 2, FIG. 3(a), FIG. 3(b), FIG. 4, FIG. 5(a) to FIG. 5(c) in the first embodiment. 6(a), 6(b), 7(a) to 7(c), and 8(a) and 8(b), the same reference numerals are used, and the related parts are omitted. Detailed description.

第3實施形態中，作為照明裝置的防犯燈10中所具有的器具本體15，是由金屬例如鋁壓鑄件而製成，利用螺釘(screw cramp)等而固定在此器具本體15的內表面上的安裝板17也是由金屬製成，優選由導熱性良好的金屬例如鋁製成。安裝板17包括邊部17c、17c和棱部17b，且與長度方向正交的方向上的截面呈V字狀，此邊部17c、17c構成各自的背面相對向的一對安裝部，此棱部17b與所述邊部17c、17c連接成一體。另外，棱部17b可呈尖形，也可不呈尖形。第3實施形態中的安裝板17也可不具有相當於第1實施形態中所述的上側反射體的結構。In the third embodiment, the fixture main body 15 included in the tamper-proof lamp 10 of the illuminating device is made of a metal such as an aluminum die-casting material, and is fixed to the inner surface of the ware body 15 by a screw or the like. The mounting plate 17 is also made of metal, preferably made of a metal having good thermal conductivity such as aluminum. The mounting plate 17 includes side portions 17c and 17c and a rib portion 17b, and has a V-shaped cross section in a direction orthogonal to the longitudinal direction. The side portions 17c and 17c constitute a pair of mounting portions on which the respective back faces face each other. The portion 17b is integrally connected to the side portions 17c and 17c. Further, the rib portion 17b may or may not have a pointed shape. The mounting plate 17 in the third embodiment does not have a configuration corresponding to the upper reflector described in the first embodiment.

如圖14所示，與穿過棱部17b的鉛垂線C正交的水平線D、和兩邊部17c、17c所成的張角θ1為30°～60°。利用此張角θ1，在光源體12已點燈的狀態下，可拉長防犯燈10的兩側斜下方的照射距離。也就是說，可使防犯燈10沿著需要照明的道路的長度方向(延伸方向)對例如17.5m的範圍照射光。As shown in Fig. 14, the horizontal line D orthogonal to the vertical line C passing through the ridge portion 17b and the opening angle θ1 formed by the both side portions 17c and 17c are 30 to 60 degrees. With this opening angle θ1, in the state where the light source body 12 has been lit, the irradiation distance obliquely downward on both sides of the tamper-proof lamp 10 can be elongated. That is, the tamper-resistant lamp 10 can be irradiated with light in a longitudinal direction (extension direction) of a road to be illuminated, for example, in a range of 17.5 m.

沿安裝板17的長度方向並排安裝在兩邊部17c、17c的表面上的多個光源體(光源模組)12，如圖18(A)至圖18(D)及圖19(A)、圖19(B)所示，包括：反射體(反射構件)14、與此反射體14的背面相重疊的模組基板11a、以及安裝在此模組基板上的多個LED(發光元件)11。A plurality of light source bodies (light source modules) 12 mounted on the surfaces of the side portions 17c, 17c side by side along the longitudinal direction of the mounting plate 17, as shown in Figs. 18(A) to 18(D) and Fig. 19(A) and Fig. 19(B) includes a reflector (reflecting member) 14, a module substrate 11a overlapping the back surface of the reflector 14, and a plurality of LEDs (light emitting elements) 11 mounted on the module substrate.

作為反射體14，可例如在PBT或ABS等合成樹脂的成形體的表面上蒸鍍(vapor deposition)鋁(也可為銀)而形成。另外，蒸鍍僅針對圖18(B)～(D)中的尺寸E1所示的範圍，反射體14的安裝側的部位即尺寸E2的範圍內不進行蒸鍍。反射體14具有沿其長度方向延伸的導水槽狀的反射面14a。此反射面14a利用所蒸鍍的鋁而成為鏡面。The reflector 14 can be formed, for example, by vapor deposition of aluminum (may be silver) on the surface of a molded body of a synthetic resin such as PBT or ABS. In addition, the vapor deposition is only performed on the range indicated by the dimension E1 in FIGS. 18(B) to (D), and the vapor deposition is not performed in the range of the dimension E2 which is the portion on the mounting side of the reflector 14. The reflector 14 has a water-conducting reflecting surface 14a extending in the longitudinal direction thereof. This reflecting surface 14a is mirror-finished by the vapor-deposited aluminum.

反射體14的開口幅度E(參照圖17(A)、圖17(B))為20mm～50mm。利用此開口幅度E，可使光源體12甚至防犯燈10小型化，而且能使從光源體12射出的光的寬度不會過窄，從而對預期的照射範圍進行照射。具體地說，就道路照明而言，可對出射光進行控制，使其能對道路的整個寬度範圍進行照明。The opening width E (see FIGS. 17(A) and 17(B)) of the reflector 14 is 20 mm to 50 mm. With this opening width E, the light source body 12 can be miniaturized even with the lamp 10, and the width of the light emitted from the light source body 12 can be made too narrow to illuminate the intended irradiation range. Specifically, in the case of road lighting, the outgoing light can be controlled to illuminate the entire width of the road.

如圖17(B)及圖19(B)所示，反射體14的寬度方向(是指與所述長度方向正交的方向)中央部設有長孔14b。長孔14b沿著反射體14的長度方向延伸，由此長孔14b將反射面14a在反射體14的寬度方向(左右方向)分成兩部分。As shown in Fig. 17 (B) and Fig. 19 (B), a long hole 14b is provided in the center portion of the reflector 14 in the width direction (the direction orthogonal to the longitudinal direction). The long hole 14b extends in the longitudinal direction of the reflector 14, whereby the long hole 14b divides the reflection surface 14a into two in the width direction (left-right direction) of the reflector 14.

第3實施形態中的反射體14中，一體形成著構成上側反射構件的反射壁部14c。如圖17(A)及圖18(D)所示，反射壁部14c將反射體14的上端部封閉，且從反射面14a的上端起呈直角彎曲而連續形成。反射壁部14c的下表面是平坦的，且通過蒸鍍的鋁而成為鏡面。另外，此蒸鍍的範圍處於所述尺寸E1的範圍內。In the reflector 14 of the third embodiment, the reflection wall portion 14c constituting the upper reflection member is integrally formed. As shown in Fig. 17 (A) and Fig. 18 (D), the reflection wall portion 14c closes the upper end portion of the reflector 14, and is formed to be continuously bent at a right angle from the upper end of the reflection surface 14a. The lower surface of the reflective wall portion 14c is flat and is mirror-finished by vapor-deposited aluminum. In addition, the range of this vapor deposition is in the range of the size E1.

反射體14的下端部無相當於反射壁部14c的結構，因此，如圖17(A)及圖19(A)、圖19(B)所示，反射體14的下端是開放的。因此，如圖18(A)所示，從正面觀察反射體14時，長孔14b的3方被包圍。也就是說，長孔14b的左右兩側被反射面14a包圍，而長孔14b的上方被反射壁部14c包圍。Since the lower end portion of the reflector 14 has no structure corresponding to the reflection wall portion 14c, the lower end of the reflector 14 is open as shown in Figs. 17(A) and 19(A) and 19(B). Therefore, as shown in FIG. 18(A), when the reflector 14 is viewed from the front, the three sides of the long hole 14b are surrounded. That is, the left and right sides of the long hole 14b are surrounded by the reflecting surface 14a, and the upper side of the long hole 14b is surrounded by the reflecting wall portion 14c.

反射體14具有從其上端向上方一體突出的上側固定部14d、和從其下端向上方一體突出的下側固定部14e。如圖18(A)、圖18(D)所示，上下固定部14d、14e的中央部形成著供螺釘等固定零件穿過的通孔。The reflector 14 has an upper fixing portion 14d that integrally protrudes upward from the upper end thereof, and a lower fixing portion 14e that integrally protrudes upward from the lower end thereof. As shown in FIGS. 18(A) and 18(D), the center portions of the upper and lower fixing portions 14d and 14e are formed with through holes through which fixing members such as screws pass.

如圖19(B)所示，在反射體14的背面、例如固定部14d、14e的中央部背面分別一體地突設著嵌合凸部14f，所述通孔形成在此嵌合凸部14f上。而且，在反射體14的背面，在嵌合凸部14f以外的位置上，突設著與此反射體14成一體的例如一對扣合爪14g。這些扣合爪14g能以其根部為支點而產生彈性變形。As shown in Fig. 19(B), a fitting convex portion 14f is integrally formed on the back surface of the reflector 14, for example, the central portion of the fixing portions 14d and 14e, and the through hole is formed in the fitting convex portion 14f. on. Further, on the back surface of the reflector 14, for example, a pair of fastening claws 14g integrally formed with the reflector 14 are protruded at positions other than the fitting convex portion 14f. These engaging claws 14g can be elastically deformed with their roots as a fulcrum.

模組基板11a是由大小與反射體14的背面大致相等的電絕緣板、佈線圖案(wiring pattern)、以及作為散熱器(heat spreader)的銅箔構成。為了將LED11串聯，而將佈線圖案設在電絕緣板的表面上。銅箔以與佈線圖案電絕緣的狀態而連續地跨設在電絕緣板的表裏兩面上。The module substrate 11a is composed of an electrically insulating plate having a size substantially equal to the back surface of the reflector 14, a wiring pattern, and a copper foil as a heat spreader. In order to connect the LEDs 11 in series, a wiring pattern is provided on the surface of the electrically insulating plate. The copper foil is continuously spanned on both the front and back sides of the electrically insulating plate in a state of being electrically insulated from the wiring pattern.

如圖19(A)、圖19(B)所示，在模組基板11a的長度方向兩端部中央分別設著嵌合部21。這一對嵌合部21，對應於嵌合凸部14f的形狀，而由例如模組基板11a的長度方向上的這一端開放的U字形的槽構成。另外，當嵌合凸部14f的形狀為圓形時，嵌合部21也可由圓形的孔等形成。As shown in FIGS. 19(A) and 19(B), the fitting portion 21 is provided at the center of both end portions in the longitudinal direction of the module substrate 11a. The pair of fitting portions 21 are formed of U-shaped grooves that are open at the end in the longitudinal direction of the module substrate 11a, for example, corresponding to the shape of the fitting convex portion 14f. In addition, when fitting When the shape of the convex portion 14f is a circular shape, the fitting portion 21 may be formed by a circular hole or the like.

進而，如圖19(A)、圖19(B)所示，模組基板11a的兩側邊緣的中央部背面分別設著爪托槽22。另外，也可省略以所述方式設置在嵌合部21以外的位置上的爪托槽22。但是，在將所述扣合爪14g的扣合部位設為在模組基板11a的側邊緣處開放的爪托槽22的構成中，扣合爪14g不會突出在反射體14的寬度方向上。這樣，如下文所述，可並排設置反射體14，且能使鄰接的反射體14之間不會產生太大間隙，而緊密地配置多個反射體14，甚至能促進防犯燈10的小型化，因此較好。Further, as shown in FIGS. 19(A) and 19(B), the claw groove 22 is provided on the back surface of the center portion of both side edges of the module substrate 11a. Further, the claw bracket 22 provided at a position other than the fitting portion 21 in the above manner may be omitted. However, in the configuration in which the engaging portion of the engaging claw 14g is the claw bracket groove 22 opened at the side edge of the module substrate 11a, the engaging claw 14g does not protrude in the width direction of the reflector 14. . Thus, as described below, the reflectors 14 can be arranged side by side, and the gaps 14 can be arranged in a close manner without causing too much gap between the adjacent reflectors 14, and even the miniaturization of the lamp 10 can be promoted. Therefore, it is better.

將模組基板11a的嵌合部21分別嵌合在反射體14的嵌合凸部14f內，並且將反射體14的扣合爪14g分別扣合於爪托槽22，借此，如圖17(A)、圖17(B)及圖18(A)至圖18(D)所示，將所述模組基板11a安裝並保持為如下的狀態，即，定位並積層在反射體14的背面上的狀態。這樣，當將光源體12安裝到安裝板17上時，無需分別安裝模組基板11a和反射體14，而可將模組基板11a和反射體14作為組件(assembly)而安裝。The fitting portions 21 of the module substrate 11a are fitted into the fitting convex portions 14f of the reflector 14, and the engaging claws 14g of the reflector 14 are respectively engaged with the claw brackets 22, whereby, as shown in Fig. 17, (A), FIG. 17(B), and FIG. 18(A) to FIG. 18(D), the module substrate 11a is mounted and held in a state of being positioned and laminated on the back surface of the reflector 14. The state on the top. Thus, when the light source body 12 is mounted on the mounting board 17, the module substrate 11a and the reflector 14 need not be separately mounted, and the module substrate 11a and the reflector 14 can be mounted as an assembly.

如圖17(B)等所示，LED11與所述佈線圖案電連接而安裝在模組基板11a的表面(安裝面)上。具體地說，如以圖18(A)、圖18(D)為代表的圖所示，LED11具有分別向反方向突出的陽極(電極)11c和陰極(電極)11d，通過焊接而將這些電極安裝在所述佈線圖案上。此時，LED11安裝成，陽極11c和陰極11d排列在模組基板11a的長度方向、換而言之是各LED11所組成的直線狀的列的延伸方向上。而且，也可設置散熱構件(未圖示)，來使各LED11的模組基板11a側和陽極11c熱連接從而進行散熱。此時，陽極11c側的溫度比陰極11d的溫度容易上升，因此，通過使陽極11c和陰極11d相對向地配置，可使模組基板11a實現均熱化，抑制各LED11的溫度的不均。As shown in FIG. 17(B) and the like, the LED 11 is electrically connected to the wiring pattern and mounted on the surface (mounting surface) of the module substrate 11a. Specifically, as shown in the diagrams represented by Figs. 18(A) and 18(D), the LED 11 has an anode (electrode) 11c and a cathode (electrode) 11d which protrude in opposite directions, respectively, and these electrodes are welded by welding. Mounted on the wiring pattern. At this time, the LED 11 is mounted such that the anode 11c and the cathode 11d are arranged in the longitudinal direction of the module substrate 11a, in other words, in the extending direction of the linear columns composed of the respective LEDs 11. Further, a heat dissipating member (not shown) may be provided to thermally connect the module substrate 11a side of each of the LEDs 11 and the anode 11c to dissipate heat. At this time, since the temperature of the anode 11c side is higher than the temperature of the cathode 11d, the anode substrate 11c and the cathode 11d are disposed to face each other, so that the module substrate 11a can be uniformly heated, and the temperature unevenness of each of the LEDs 11 can be suppressed.

各LED11的安裝間隔F為5mm～20mm。通過如上所述使LED11的安裝間隔F大於等於5mm，可抑制射向LED11所組成的列的延伸方向的光被鄰接的LED11遮住而導致光的出射效率下降。而且，通過將LED11的安裝間隔F設成小於等於20mm，不僅能抑制各個LED11分別被看成一個光點，而且能使光源看上去較大從而減少眩目感。The mounting interval F of each of the LEDs 11 is 5 mm to 20 mm. By setting the mounting interval F of the LEDs 11 to 5 mm or more as described above, it is possible to suppress light that is emitted in the extending direction of the column composed of the LEDs 11 from being blocked by the adjacent LEDs 11 and to cause a decrease in the light emission efficiency. Further, by setting the mounting interval F of the LEDs 11 to 20 mm or less, it is possible to suppress not only that each of the LEDs 11 is regarded as one spot, but also to make the light source appear large to reduce glare.

通過如上所述對安裝著多個LED11的模組基板11a和反射體14進行組裝，各LED11面向反射體14的內側、且從正面觀察反射體14時其配置在所述長孔14b內。也就是說，成列的多個LED11，以映入到反射體14的寬度方向兩側部位、也就是說反射面14a的左右兩側的方式，而配設在反射面14a的內側且位於寬度方向中央部。By assembling the module substrate 11a and the reflector 14 to which the plurality of LEDs 11 are mounted as described above, each of the LEDs 11 faces the inside of the reflector 14, and is disposed in the long hole 14b when the reflector 14 is viewed from the front. In other words, the plurality of LEDs 11 arranged in the row are disposed on the inner side of the reflection surface 14a and on the inner side of the reflection surface 14a so as to be reflected on both sides in the width direction of the reflector 14, that is, on the left and right sides of the reflection surface 14a. Direction in the center.

換而言之，反射體14的寬度方向兩側部位是以多個LED11所組成的列為中心而左右對稱地設置的。因此，各LED11與它們所映入的反射體14的寬度方向兩側部位之間的距離是相等的，因此，反射面14a對於排成列的各LED11的反射的控制是相同的，因此，可將光擴散到道路的整個橫向範圍，且沿著道路的延伸方向對規定長度範圍進行照明。相反，排成列的各LED11與反射壁部14c之間的距離各不相同，反射壁部14c的反射面主要使來自與其最近的位置上的LED11的光向下方反射。In other words, the both sides in the width direction of the reflector 14 are disposed bilaterally symmetrically around the column composed of the plurality of LEDs 11. Therefore, the distance between the LEDs 11 and the two sides of the reflector 14 reflected in the width direction is equal. Therefore, the control of the reflection of the LEDs 11 arranged in the column 11 is the same, and therefore, The light is spread over the entire lateral extent of the road and the specified length range is illuminated along the direction of extension of the road. On the contrary, the distance between each of the LEDs 11 arranged in a row and the reflection wall portion 14c is different, and the reflection surface of the reflection wall portion 14c mainly reflects the light from the LED 11 at the position closest thereto.

而且，如圖18(C)所示，LED11的光出射正面(圖18(C)中為上表面)的高度位置，並不位於反射體14的反射面14a的焦點G，而使設在相對於此焦點G偏向背面方向(圖18(C)中為下方)2mm(將此稱作-2mm)的範圍K1內，或者，設在相對於焦點G偏向正面方向(圖18(C)中為上方)2mm(將此稱作+2mm)的範圍K2內。這樣，可防止來自各LED11的光成為平行光而射出，且可使出射光擴散而高效地照射在路面等上。Further, as shown in Fig. 18(C), the height position of the light emitting front surface of the LED 11 (the upper surface in Fig. 18(C)) is not located at the focal point G of the reflecting surface 14a of the reflector 14, but is set to be relatively The focus G is biased in the range K1 of the back surface direction (lower in FIG. 18(C)) by 2 mm (this is referred to as -2 mm), or is set to be in the front direction with respect to the focus G (Fig. 18(C) The upper part is within the range K2 of 2 mm (this is called +2 mm). In this way, it is possible to prevent the light from each of the LEDs 11 from being emitted as parallel light, and to diffuse the emitted light to efficiently illuminate the road surface or the like.

而且，因各LED11是以模組基板11a保持在反射體14上的狀態下而配置在長孔14b內，所以，當從正面觀察光源體12時，這些LED11的陽極11c及陰極11d並不被反射體14覆蓋，而是處於露出在反射體14的內側的狀態。這樣，在LED11點燈的狀態下，傳遞給配設在最靠近此LED11的發熱部的金屬製的陽極11c、陰極11d、以及焊料的LED11的熱，不會受到反射體14的阻擋而可釋放到空氣中。所述熱的釋放，尤其是在後述的未使用限光體(外罩)13時得到促進。而且，隨著這樣的散熱，能抑制各LED11的溫度上升，從而抑制了發光效率及使用壽命的下降。Further, since the LEDs 11 are disposed in the long holes 14b while the module substrate 11a is held by the reflector 14, the anodes 11c and the cathodes 11d of the LEDs 11 are not viewed when the light source body 12 is viewed from the front. The reflector 14 is covered, but is exposed to the inside of the reflector 14. In this way, in the state where the LED 11 is lit, the heat transmitted to the metal anode 11c, the cathode 11d, and the solder LED 11 disposed closest to the heat generating portion of the LED 11 is released without being blocked by the reflector 14. Into the air. The release of the heat is promoted especially when the light-restricting body (cover) 13 is not described later. Further, with such heat dissipation, the temperature rise of each of the LEDs 11 can be suppressed, and the decrease in luminous efficiency and the service life can be suppressed.

而且，各LED11是排成直線狀的列，它們與長孔14b的兩側邊緣之間形成狹縫狀的間隙。因此，經過所述狹縫狀間隙的空氣流，能抑制熱停留在各LED11的周圍，從而促進這些LED11散熱，因此，各LED11之間不會產生溫度差。所述熱的釋放，尤其是在後述的未使用限光體(外罩)13時得到促進。而且，隨著這樣的散熱，能夠抑制各LED11的光束的發光色產生不均。Further, each of the LEDs 11 is a row arranged in a straight line, and a slit-like gap is formed between both the edges of the long holes 14b. Therefore, the air flow passing through the slit-like gap can suppress the heat from staying around the respective LEDs 11 and promote the heat dissipation of the LEDs 11. Therefore, a temperature difference does not occur between the LEDs 11. The release of the heat is promoted especially when the light-restricting body (cover) 13 is not described later. Further, with such heat dissipation, it is possible to suppress unevenness in the luminescent color of the light beam of each of the LEDs 11.

另外，第3實施形態中，為了促進LED11的散熱，而使陽極11c和陰極11d及它們的焊接部分露出在限光體13的內側，但也可不使用這樣的方式，而是由反射體14來覆蓋陽極11c與陰極11d中的一方及其焊接部分。此時，也能隨著提高LED11的散熱性，而抑制發光性能的下降。也就是說，通過使陽極11c與陰極11d中至少有一方露出在限光體13的內側，而不僅通過模組基板11a進行後述散熱，而且也可向限光體13的內側散熱。因此，能抑制發光性能的下降，從而形成高性能的防犯燈10。Further, in the third embodiment, in order to promote heat dissipation of the LED 11, the anode 11c and the cathode 11d and the welded portions thereof are exposed inside the light-restricting body 13, but the reflector 14 may be used instead of the above-described method. One of the anode 11c and the cathode 11d and its welded portion are covered. At this time, it is also possible to suppress a decrease in the light-emitting performance as the heat dissipation of the LED 11 is improved. In other words, at least one of the anode 11c and the cathode 11d is exposed inside the light-restricting body 13, and heat can be radiated not only by the module substrate 11a but also to the inside of the light-restricting body 13. Therefore, it is possible to suppress a decrease in luminescent performance, thereby forming a high-performance tamper-proof lamp 10.

各光源體12，沿著安裝板17的兩邊部17c的長度方向而排列且固定在兩邊部17c的表面上。所述固定，是利用固定零件，例如是穿過光源體12的上下固定部14d、14e的通孔而擰入至邊部17c的螺釘25(圖14參照)而實現的。利用螺釘25的緊固，來使模組基板11a由反射體14和安裝板17夾著且固定，從而以能導熱的方式貼緊反射體14的背面和邊部17c的表面。因此，當將防犯燈10點亮時，LED11所放出的大多數的熱，會經過模組基板11a而傳遞給安裝板17，再從此安裝板17傳遞給器具本體15，最後從器具本體15的表面釋放到大氣中。在這樣的LED11的散熱過程中，如上所述，模組基板11a上設著銅箔作為散熱器，因此，可從模組基板11a經過此銅箔而向安裝板17高效地散熱。另外，模組基板11a上的銅箔和反射體14的蒸鍍層之間並不是連續的。Each of the light source bodies 12 is arranged along the longitudinal direction of the both side portions 17c of the mounting plate 17 and fixed to the surfaces of the both side portions 17c. The fixing is achieved by a fixing member, for example, a screw 25 (refer to FIG. 14) that is screwed into the side portion 17c through a through hole of the upper and lower fixing portions 14d and 14e of the light source body 12. By fastening the screws 25, the module substrate 11a is sandwiched and fixed by the reflector 14 and the mounting plate 17, so that the back surface of the reflector 14 and the surface of the side portion 17c can be adhered to each other in a thermally conductive manner. Therefore, when the security light 10 is turned on, most of the heat emitted by the LED 11 is transmitted to the mounting board 17 through the module substrate 11a, and then transmitted from the mounting board 17 to the appliance body 15, and finally from the appliance body 15. The surface is released into the atmosphere. In the heat dissipation process of the LEDs 11, as described above, the module substrate 11a is provided with a copper foil as a heat sink. Therefore, the module substrate 11a can efficiently dissipate heat to the mounting board 17 through the copper foil. Further, the copper foil on the module substrate 11a and the vapor deposition layer of the reflector 14 are not continuous.

圖15(A)、圖15(B)、圖16中表示各光源體12並排配置的狀態。各光源體12具有的多個LED11所組成的列的延伸方向，與各光源體12的排列方向正交。例如，在圖16所示的狀態下，各光源體12是橫向排列的，相反，各光源體12的LED11列是縱向排列的。15(A), 15(B), and 16 show a state in which the respective light source bodies 12 are arranged side by side. The extending direction of the columns of the plurality of LEDs 11 included in each of the light source bodies 12 is orthogonal to the arrangement direction of the respective light source bodies 12. For example, in the state shown in Fig. 16, the respective light source bodies 12 are arranged side by side, and conversely, the columns of the LEDs 11 of the respective light source bodies 12 are arranged in the longitudinal direction.

而且，如圖16所示，固定在安裝板17上的各光源體12的LED列間的相互間隔I是30mm～70mm。通過設置這樣的間隔，並排設置的光源體12的LED列不易被視作獨立的列，視覺上，各光源體12容易被視作沿器具本體15的長度方向的一個光源。這樣的光源體12的並排設置可通過如下方式而實現：如上所述在光源體12的上下方設置固定部14d、14e，而使排列方向上鄰接的光源體12間的相互間隔最小，從而獲得所述的相互間隔I。Further, as shown in Fig. 16, the mutual interval I between the LED rows of the respective light source bodies 12 fixed to the mounting board 17 is 30 mm to 70 mm. By providing such an interval, the LED rows of the light source bodies 12 arranged side by side are not easily regarded as independent columns, and visually, each light source body 12 is easily regarded as one light source along the longitudinal direction of the fixture body 15. Such side-by-side arrangement of the light source bodies 12 can be realized by providing the fixing portions 14d and 14e above and below the light source body 12 as described above, and minimizing the mutual spacing between the adjacent light source bodies 12 in the arrangement direction, thereby obtaining Said mutual spacing I.

如上所述對固定著多個光源體12的安裝板17進行支撐的器具本體15，如圖11所示，利用支撐構件16和安裝帶19，而固定支撐在以規定間隔設立在道路上的支柱P的上部。此時，如圖15(A)所示，相對于支柱P的軸線、也就是說鉛垂線J，器具本體15以越靠近道路中央部側越高的方式而傾斜向上地傾斜固定。此傾斜角θ2為10°～40°。通過設置這樣的傾斜角θ2，可使光照射到道路的橫向的中央部，從而可提高照射面的照度。而且，通過設置以上的傾斜角θ2，在設著防犯燈10的狀態下，從側方觀察器具本體15時，各LED列是以上側更靠近鉛垂線J的方式而傾斜排列的，同樣，構成反射體14的導水槽狀的反射面14a也是以上側更靠近鉛垂線J的方式傾斜配設的。As described above, the luminaire main body 15 that supports the mounting plate 17 to which the plurality of light source bodies 12 are fixed is fixedly supported by the support members 16 and the mounting belt 19 at a predetermined interval on the road as shown in FIG. The upper part of P. At this time, as shown in FIG. 15(A), the luminaire main body 15 is inclined and fixed obliquely upward with respect to the axis of the strut P, that is, the vertical line J, so that the instrument body 15 is higher toward the center portion of the road. This inclination angle θ2 is 10° to 40°. By providing such an inclination angle θ2, light can be irradiated to the central portion of the road in the lateral direction, and the illuminance of the irradiation surface can be improved. By providing the above-described inclination angle θ2, when the fixture main body 15 is viewed from the side in the state where the tamper-proof lamp 10 is provided, the LED rows are arranged obliquely so that the upper side is closer to the vertical line J, and the same configuration is performed. The water-conducting-shaped reflecting surface 14a of the reflector 14 is also disposed obliquely so that the upper side is closer to the vertical line J.

而且，作為外罩的限光體13，由器具本體15支撐，且覆蓋各光源體12和安裝板17等。限光體13是由透明的丙烯酸樹脂等透光性合成樹脂形成的，為了不能從外部透視到其內部，而對其表面進行磨砂加工。如圖12至圖14所示，限光體13具有一對第1透光部13f和一對第2透光部13g。第1透光部13f與安裝板17的傾斜的兩邊部17c大致平行，這樣，使得此第1透光部13f與由反射體14的反射面14a所反射的光的出射方向正交。第2透光部13g，從第1透光部13f的下邊緣斜向上彎曲，且與反射壁部14c相對向地設在其下方。這樣，使此第2透光部13g與由反射壁部14c朝向下方反射的光的出射方向正交。Further, the light-restricting body 13 as the outer cover is supported by the luminaire main body 15 and covers the respective light source bodies 12, the mounting plates 17, and the like. The light-restricting body 13 is formed of a translucent synthetic resin such as a transparent acrylic resin, and the surface thereof is subjected to a sanding process so as not to be seen from the outside to the inside thereof. As shown in FIGS. 12 to 14, the light-limiting body 13 has a pair of first light-transmitting portions 13f and a pair of second light-transmitting portions 13g. The first light transmitting portion 13f is substantially parallel to the inclined side portions 17c of the mounting plate 17, such that the first light transmitting portion 13f is orthogonal to the direction in which the light reflected by the reflecting surface 14a of the reflector 14 is emitted. The second light transmitting portion 13g is bent obliquely upward from the lower edge of the first light transmitting portion 13f, and is provided below the reflecting wall portion 14c. In this way, the second light transmitting portion 13g is orthogonal to the emission direction of the light reflected downward by the reflecting wall portion 14c.

通過採用如上所述的限光體13，具有以下優點。即，由各光源體12的反射面14a所反射的光和從各LED11射出且直接入射到第1透光部13f的光，可穿過從側方而與此反射面14a相對向的限光體13的第1透光部13f。此時，第1透光部13f與要穿過它的光(圖14中以箭頭N表示)的出射方向正交，因此，入射到第1透光部13f的光難以被第1透光部13f反射，而容易穿過第1透光部13f。同樣，由反射壁部14c反射的光及主要從位於最下方的LED11射出且直接入射到第2透光部13g的光，可穿過從下方與此反射壁部14c相對向的限光體13的第2透光部13g。此時，第2透光部13g與要穿過它的光(圖14中以箭頭M表示)的出射方向正交，因此，入射到第2透光部13g的光難以被第2透光部13g反射，而容易穿過第2透光部13g。因此，限光體13上的光損耗減少，隨之，可高效地照射光。By adopting the light-restricting body 13 as described above, the following advantages are obtained. In other words, the light reflected by the reflecting surface 14a of each of the light source bodies 12 and the light that is emitted from the respective LEDs 11 and directly incident on the first light transmitting portion 13f can pass through the light-receiving light that faces the reflecting surface 14a from the side. The first light transmitting portion 13f of the body 13. At this time, since the first light transmitting portion 13f is orthogonal to the direction in which the light to be passed therethrough (indicated by the arrow N in FIG. 14), the light incident on the first light transmitting portion 13f is hardly blocked by the first light transmitting portion. 13f reflects and easily passes through the first light transmitting portion 13f. Similarly, the light reflected by the reflecting wall portion 14c and the light that is emitted mainly from the lowermost LED 11 and directly incident on the second light transmitting portion 13g can pass through the light limiting body 13 opposed to the reflecting wall portion 14c from below. The second light transmitting portion 13g. At this time, since the second light transmitting portion 13g is orthogonal to the direction in which the light to be passed therethrough (indicated by the arrow M in FIG. 14), the light incident on the second light transmitting portion 13g is hardly affected by the second light transmitting portion. 13 g is reflected and easily passes through the second light transmitting portion 13g. Therefore, the light loss on the light-restricting body 13 is reduced, and accordingly, the light can be efficiently irradiated.

根據以所述方式構成的防犯燈10，多個LED11沿著具有導水槽狀的反射面14a的反射體14的延伸方向而排列成列，而且，將具有所述LED11的列的多個光源體12並排設在器具本體15的長度方向上，因此可簡化LED11的排列。而且，各光源體12具有反射體14，且此反射體14具有由鏡面構成的導水槽狀的反射面14a，利用所述反射體14可對LED11發出的光的配光進行控制從而進行照明，因此，可利用並排設在器具本體15的長度方向上的光源體12來實現廣範圍的照明。According to the security light 10 configured as described above, the plurality of LEDs 11 are arranged in a row along the extending direction of the reflector 14 having the water guiding groove-shaped reflecting surface 14a, and a plurality of light source bodies having the columns of the LEDs 11 are arranged. The 12 is arranged side by side in the longitudinal direction of the fixture body 15, so that the arrangement of the LEDs 11 can be simplified. Further, each of the light source bodies 12 has a reflector 14, and the reflector 14 has a channel-shaped reflecting surface 14a formed of a mirror surface, and the reflector 14 can control the light distribution of the light emitted from the LEDs 11 to illuminate the light source. Therefore, a wide range of illumination can be realized by the light source body 12 arranged side by side in the longitudinal direction of the fixture body 15.

而且，組合在反射體14上的LED11的列，配設在反射體14所具有的導水槽狀的反射面14a的內側、且位於寬度方向的中央部，因此，此LED11列會分別映入收容著LED11的列的反射面14a的寬度方向的兩側部位。這樣，各個LED11原本較小且為高亮度，但因映入到反射面14a上而形成LED11列的像，從而使防犯燈10的視覺上的光源變大。也就是說，視覺上，所配置的光源要比實際用作光源的LED11的數量多，因此，使得使用的光源變大。因此，可減少由多個光源體12構成的光源產生的眩目感。Further, the rows of the LEDs 11 combined on the reflector 14 are disposed inside the water-conducting reflecting surface 14a of the reflector 14, and are located at the central portion in the width direction. Therefore, the LEDs 11 are separately accommodated. Both sides of the reflection surface 14a of the row of the LEDs 11 in the width direction are formed. Thus, each of the LEDs 11 is originally small and high in brightness, but forms an image of the columns of the LEDs 11 by being reflected on the reflecting surface 14a, thereby making the visual light source of the tamper-proof lamp 10 large. That is to say, visually, the configured light source is larger than the number of LEDs 11 actually used as the light source, and therefore, the light source used is made larger. Therefore, the glare generated by the light source composed of the plurality of light source bodies 12 can be reduced.

此時，各LED11與它們所映入的反射體14的寬度方向兩側部位之間的距離是相等的，因此反射面14a對於排成列的各LED11的反射的控制是相同的。因此，可實現廣範圍的照明，也就是說，圖14中箭頭N所表示的光經過反射面14a而擴散到道路的整個橫向範圍，且沿著道路的延伸方向一直到達遠處，從而對道路進行規定長度範圍的照明。At this time, since the distance between each of the LEDs 11 and the both sides in the width direction of the reflector 14 reflected by them is equal, the control of the reflection of the reflection surface 14a for each of the LEDs 11 arranged in a row is the same. Therefore, a wide range of illumination can be realized, that is, the light indicated by the arrow N in FIG. 14 is diffused to the entire lateral extent of the road through the reflecting surface 14a, and reaches the far distance along the extending direction of the road, thereby Perform illumination for a specified length range.

另外，可使用透鏡來對防犯燈的配光進行控制，但此時，光源的亮度較高，容易產生眩目感，因此不理想。不僅如此，當需要大光量時，須相應地設置大量的LED，從而，對來自這些LED的出射光進行控制的透鏡必然會變大，因此在成本方面不利。而且，當使用多個較小的透鏡來控制配光時，不僅是組裝上比較複雜，而且通過多個透鏡的光會使得光源看上去是各自獨立的，因此，會看到多個高亮度的LED，具有強烈的顆粒感，眩目感較強，因此不理想。但是，第3實施形態中的防犯燈中，是使用如上所述利用反射而使視覺上的光源變大的光源體12來進行配光控制的，因此不會出現以上的不良現象。Further, the lens can be used to control the light distribution of the tamper-proof lamp. However, at this time, the brightness of the light source is high, and glare is likely to occur, which is not preferable. Moreover, when a large amount of light is required, a large number of LEDs must be provided correspondingly, so that the lens for controlling the outgoing light from these LEDs is inevitably large, and thus it is disadvantageous in terms of cost. Moreover, when using a plurality of smaller lenses to control the light distribution, not only is the assembly complicated, but the light passing through the plurality of lenses makes the light sources appear to be independent, and thus, a plurality of high-brightness LEDs have a strong graininess and a strong glare, so they are not ideal. However, in the tamper-proof lamp according to the third embodiment, the light source body 12 that uses the reflection to increase the visual light source is used to perform light distribution control, and thus the above-described problem does not occur.

另外，下端開放的反射體14上，設著上側開口被封閉的反射壁部14c，因此，利用此反射壁部14c的下表面的反射面，主要將從位於最上方LED11射向上方的光朝下方反射，而使LED11射出的光不會穿過防犯燈10的上方而造成損耗。這樣，可減少因防犯燈10向上方漏光而產生的光污染，而且，利用圖14中箭頭M所表示的光進行照明時，可確保防犯燈10的大致正下方的亮度。Further, since the reflector 14 having the lower opening is provided with the reflection wall portion 14c whose upper opening is closed, the reflection surface of the lower surface of the reflection wall portion 14c is mainly directed upward from the uppermost LED 11 The reflection is made downward, and the light emitted from the LED 11 does not pass through the top of the security light 10 to cause loss. In this way, it is possible to reduce light pollution caused by the light leakage from the lamp 10, and when the illumination is performed by the light indicated by the arrow M in FIG. 14, the brightness of the lamp 10 can be ensured substantially directly below.

圖20中表示以所述方式構成的防犯燈10的配光特性。圖20中虛線所示的Q，表示以經過安裝板17的棱部17b的鉛垂線為基準的、器具本體15的長度方向(是指以光源模組12的排列方向上的鉛垂線為基準的、所述光源模組12的排列方向)上的配光特性。此配光特性Q是沿防犯燈10的長度方向(圖12中以兩點鏈線Q1表示)所測定出的配光特性，圖20中0°表示防犯燈10的正下方的亮度，將此時的亮度作為基準值100。以所述方式構成的防犯燈10具有如下的配光特性：當與所述鉛垂線所成的角度在0°～±50°的範圍內時為全光束量，而且，當與所述鉛垂線所成的角度不足0°～±20°時，光束分配率為50%～60%，當與所述鉛垂線所成的角度為±20°～±50°時，光束分配率為40%～50%。Fig. 20 shows the light distribution characteristics of the security light 10 constructed as described above. Q indicated by a broken line in FIG. 20 indicates the longitudinal direction of the luminaire main body 15 based on the vertical line passing through the ridge portion 17b of the mounting plate 17, which is based on the vertical line in the direction in which the light source modules 12 are arranged. The light distribution characteristics in the direction in which the light source modules 12 are arranged. The light distribution characteristic Q is a light distribution characteristic measured along the longitudinal direction of the tamper-proof lamp 10 (indicated by a two-dot chain line Q1 in Fig. 12), and 0° in Fig. 20 indicates the brightness immediately below the tamper-proof lamp 10, and this is The brightness at the time is taken as the reference value of 100. The security light 10 constructed as described above has a light distribution characteristic in which the total beam amount is when the angle formed with the vertical line is in the range of 0° to ±50°, and when it is opposite to the vertical line When the angle formed is less than 0° to ±20°, the beam split ratio is 50% to 60%, and when the angle with the vertical line is ±20° to ±50°, the beam split ratio is 40%. 50%.

根據所述配光特性可知，在最靠近防犯燈10的被照射面即防犯燈的正下方，可照射出高光度的點射光。這樣，可高效地提高防犯燈正下方的水平面照度。這樣，能以高亮度來對防犯燈正下方進行照明，隨之，可減少光源的刺眼感，因此，當用作防犯燈時，可降低作為眩目感指標的GR值。According to the light distribution characteristics, it is possible to illuminate a spotlight having a high illuminance directly under the illuminating surface closest to the tamper-proof lamp 10, that is, the tamper-proof lamp. In this way, the illuminance of the water level directly under the tampering lamp can be efficiently improved. In this way, it is possible to illuminate the underside of the tamper-evident lamp with high brightness, and accordingly, the glare of the light source can be reduced. Therefore, when used as a tamper-proof lamp, the GR value which is an indicator of glare can be reduced.

另外，圖20中實線所示的R，表示以經過安裝板17的棱部17b的鉛垂線為基準的、與器具本體15的長度方向(是指以光源模組12的排列方向上的鉛垂線為基準的、所述光源模組12的排列方向)正交的方向上的配光特性。此配光特性R是沿圖12中的兩點鏈線R1而測定出的配光特性。以所述方式構成的防犯燈10具有如下的配光特性：當與所述鉛垂線所成的角度不足0°～±20°時，光束分配率為10%～20%，當與所述鉛垂線所成的角度不足±20°～±50°時，光束分配率為35%～45%，當與所述鉛垂線所成的角度不足±50°～±90°時，光束分配率為35%～45%，當與所述鉛垂線所成的角度為±90°～180°時，光束分配率不足5%。In addition, R shown by the solid line in FIG. 20 indicates the lead in the direction in which the light source module 12 is arranged, based on the vertical line passing through the edge portion 17b of the mounting plate 17, and the longitudinal direction of the device body 15. The light distribution characteristics in the direction orthogonal to the alignment direction of the light source module 12 with respect to the vertical line. This light distribution characteristic R is a light distribution characteristic measured along the two-dot chain line R1 in Fig. 12 . The tamper-proof lamp 10 configured as described above has a light distribution characteristic: when the angle with the vertical line is less than 0° to ±20°, the beam distribution ratio is 10% to 20%, when the lead is When the angle formed by the perpendicular line is less than ±20° to ±50°, the beam splitting ratio is 35% to 45%, and when the angle with the vertical line is less than ±50° to ±90°, the beam splitting ratio is 35. % to 45%, when the angle formed by the vertical line is ±90° to 180°, the beam splitting ratio is less than 5%.

根據所述配光特性可知，通過將光分配到防犯燈10的左右兩側的斜下方，可對例如道路而沿著其延伸方向進行廣範圍的照明，而且，通過將光分配到防犯燈10的正下方，可提高水平面照度。因此，與圖20中Q所示的配光特性相配合，能以高亮度來對防犯燈10正下方進行照明，且可減少光源的刺眼感。這樣，當用作防犯燈10時，可降低作為眩目感指標的GR值，例如使GR值達到50以下。而且，根據圖20中Q所示的配光特性可知，防犯燈10上側的光束分配率不足5%，因此，能抑制防犯燈10上側的光污染。According to the light distribution characteristics, by distributing the light obliquely downward to the left and right sides of the security light 10, a wide range of illumination can be performed along the extending direction of, for example, the road, and by distributing the light to the security light 10 Directly below, it can improve the illumination of the water level. Therefore, in accordance with the light distribution characteristics shown by Q in Fig. 20, the direct illumination lamp 10 can be illuminated with high brightness, and the glare of the light source can be reduced. Thus, when used as the tamper-proof lamp 10, the GR value which is an indicator of glare can be lowered, for example, the GR value is 50 or less. Further, according to the light distribution characteristics shown by Q in Fig. 20, it is understood that the light beam distribution ratio on the upper side of the tamper-proof lamp 10 is less than 5%, so that light pollution on the upper side of the tamper-proof lamp 10 can be suppressed.

另外，圖21(A)、圖21(B)中為了進行比較而表示公知的防犯燈的配光特性，這些圖中，虛線及實線所示的內容與圖20相同，而且同樣將防犯燈正下方的亮度作為基準值100。而且，圖21(A)中表示使用熒光燈作為光源的防犯燈的配光特性，圖21(B)中表示使用水銀燈作為光源的防犯燈的配光特性。這些配光特性與第3實施形態中的配光特性完全不同，兩種情況下的最高亮度都較低，而且，圖21(A)所示的防犯燈難以沿道路的延伸方向照到充分遠的範圍，而圖21(B)所示的防犯燈則是正下方難以獲得充足的亮度。In addition, in FIGS. 21(A) and 21(B), the light distribution characteristics of the known security light are shown for comparison. In the figures, the contents shown by broken lines and solid lines are the same as those in FIG. 20, and the light is also protected. The brightness immediately below is taken as the reference value of 100. Further, Fig. 21(A) shows the light distribution characteristics of the tamper-proof lamp using the fluorescent lamp as the light source, and Fig. 21(B) shows the light distribution characteristics of the tamper-proof lamp using the mercury lamp as the light source. These light distribution characteristics are completely different from those of the third embodiment, and the maximum brightness in both cases is low, and the security light shown in Fig. 21(A) is hard to be sufficiently far along the extending direction of the road. The range of the security lights shown in Fig. 21(B) is that it is difficult to obtain sufficient brightness right below.
