Description

本発明は、トンネル、道路等に使用され、特に運転者の視線を車両の進行方向に誘導する照明器具に関する。    The present invention relates to a lighting apparatus that is used in tunnels, roads, and the like, and particularly guides a driver's line of sight in the traveling direction of a vehicle.

従来、例えば自動車専用道路や高速道路などに使用される照明器具は、道路の路肩側や中央分離帯などに設置されるポールに照明器具を設置し、主として路面を照明するようになっている。   2. Description of the Related Art Conventionally, lighting fixtures used, for example, on automobile-only roads and highways are designed to mainly illuminate road surfaces by installing lighting fixtures on poles installed on the shoulder side of a road or in a median strip.

近年、高速道路等には排水性を高めた高機能舗装が施工され、この高機能舗装は通常のアスファルト舗装やコンクリート舗装に比較して、路面の反射率が低く路面輝度の確保が難しくなり、先行車両の影と路面輝度との十分な輝度対比ができず、後続車両から見た先行車両の視認性が低下する問題が発生している。これは先行車両の視認に限らず、道路上の障害物や路肩に停車している車両等に対する視認性についても同様の問題が生じる。   In recent years, high-performance pavement with improved drainage has been constructed on highways, etc., and this high-performance pavement has a low road surface reflectance and difficulty in securing road surface brightness compared to normal asphalt pavement and concrete pavement. A sufficient brightness contrast between the shadow of the preceding vehicle and the road surface brightness cannot be made, and there is a problem that the visibility of the preceding vehicle as viewed from the following vehicle is lowered. This is not limited to the visual recognition of the preceding vehicle, but the same problem arises with respect to the visibility of obstacles on the road, vehicles stopped on the road shoulder, and the like.

このため、最近では路肩の低い位置等、道路の側方位置にスポットライトを設置したり、車両の進行方向に向けて光を照射する低位置追跡照明をなす照明器具が設置され、道路上に存在する先行車両や障害物、さらに路肩に停車している車両等を視認し易くしている(例えば、特許文献1)。   For this reason, recently, spotlights have been installed on the side of the road, such as at low shoulders, and lighting fixtures have been installed on the road that provide low-position tracking lighting that emits light toward the direction of travel of the vehicle. It makes it easy to visually recognize existing vehicles, obstacles, and vehicles that are stopped on the shoulder (for example, Patent Document 1).

この照明器具は路面輝度を確保できるとともに、運転者の視線を車両の進行方向に誘導する視線誘導効果を得ることができるが、この両方の効果、機能を発揮させるためには、運転者へのグレアの発生を防止するなど複雑な配光設計を行わなければならず、これを解決するために、路面輝度を確保する照明装置と、視線誘導を確保する照明装置を分けて別体に構成することによって、上記の問題を改善しようとしている(例えば、特許文献2)。
特開2003−36705号公報 特開2002―63803号公報
While this lighting fixture can secure road surface brightness and can obtain a gaze guidance effect that guides the driver's gaze in the traveling direction of the vehicle, in order to exhibit both effects and functions, In order to solve this problem, it is necessary to separate the lighting device that secures road surface brightness and the lighting device that secures line-of-sight guidance. Therefore, the above-mentioned problem is being improved (for example, Patent Document 2).

しかしながら、上記特許文献2に示される照明装置においては、視線誘導の機能をなす照明装置が、路面輝度を確保する照明装置の光量と等しいか、小さくするか、若しくは極めてわずかな光量となるように設定してはいるが、あくまでも所定の照明を行うための光量を有する照明装置で構成されており、照明装置であるが故に、一定のグレアがどうしても発生してしまい、しかも、グレアは車両の進行方向とは逆の方向、すなわち運転者に向かって、照明装置としての一定の光量を持った光として放射され、運転者には眩しく写り「まぶしさ」を感じさせてしまう。これを防止するために特許文献2に示される照明装置においても、照明装置を「まぶしさ」を感じさせない距離に配置するなどの格別の手段を講じなければならない。   However, in the illuminating device shown in Patent Document 2, the illuminating device that performs the line-of-sight guidance function is equal to or smaller than the light amount of the illuminating device that secures road surface luminance, or has an extremely small amount of light. Although it is set, it is composed of an illuminating device having a light quantity for performing predetermined illumination, and because it is an illuminating device, a certain amount of glare is inevitably generated, and in addition, glare is caused by the progress of the vehicle. The light is emitted as light having a certain amount of light as a lighting device toward the direction opposite to the direction, that is, toward the driver, and the driver feels dazzled and feels “glare”. In order to prevent this, even in the lighting device disclosed in Patent Document 2, special measures such as disposing the lighting device at a distance that does not feel “glare” must be taken.

このために、この種の視線誘導機能を有する照明器具においては、運転者に眩しく写るグレアの発生を如何に防ぎ、「まぶしさ」を感じさせないようにするかが重要な課題となっている。   For this reason, in a luminaire having this type of line-of-sight guidance function, it is an important issue how to prevent glare from appearing dazzling to the driver and avoid feeling “glare”.

Light that cannot be reflected is reflected in the vehicle traveling direction F.

表示部材3は、発光ダイオード(以下「LED」と称す)3aからなり、器具本体1の開口部1cを形成した正面板1aの車両進行方向F側の端部に、1個または複数個、本実施形態では3個のLED3aが縦一列で等間隔に設けられている。   The display member 3 is composed of a light emitting diode (hereinafter referred to as “LED”) 3 a, and one or a plurality of the display members 3 are provided at the end of the front plate 1 a in which the opening 1 c of the instrument body 1 is formed on the vehicle traveling direction F side. In the embodiment, three LEDs 3a are provided at equal intervals in a vertical row.

この各LED3aは、器具本体1の端部に形成された断面三角形状の凹部1fに傾斜して設けられた支持部1gに、その発光部3bが外面に露出するように位置して取付けられ、かつ光源部4から放射される光線が各LED3aに直接照射されないように配置して取付られる。   Each LED 3a is attached to a support portion 1g provided at an inclination in a recessed portion 1f having a triangular cross section formed at the end of the instrument body 1 so that the light emitting portion 3b is exposed to the outer surface, And it arrange | positions and is attached so that the light ray radiated | emitted from the light source part 4 may not be directly irradiated to each LED3a.

さらに、凹部1fの開口部は、器具本体1の開口部1cに連続して形成され、光透過部1bに設けられた透光カバー1dで光透過部と一緒に水密かつ気密に覆われている。   Further, the opening of the recess 1f is formed continuously with the opening 1c of the instrument body 1, and is covered with the light transmitting portion 1d with a light transmitting cover 1d provided on the light transmitting portion 1b in a watertight and airtight manner. .

各LED3aは、その軸線方向に主光軸Xを有した、白色に発光する指向性の高い高輝度LEDで構成され、上記のように傾斜した支持部1gに取付けることにより、車両の進行方向Fに反する方向に、各LED3aの主光軸Xが0〜30度の角度R2を有して向くように設置され、この3個のLED3aによって、照明装置による路面を照明するための大なる光量の光ではなく、表示機能である「縦に3個の点」、遠方からは「連続した縦線」に見える印として、その存在自体を表示する程度の光量で表示する。   Each LED 3a is composed of a high-intensity LED that emits white light and has a main optical axis X in the axial direction thereof, and is attached to the inclined support portion 1g as described above, so that the vehicle traveling direction F The LED 3a is installed so that the main optical axis X of each LED 3a faces with an angle R2 of 0 to 30 degrees, and with these three LEDs 3a, a large amount of light for illuminating the road surface by the lighting device is provided. Instead of light, it is displayed as “three vertical dots” which is a display function and “continuous vertical lines” from a distance, so that the presence itself is displayed with an amount of light that can be displayed.

同時に各LED3aの発光部3bは円筒状をなしており、主光軸Xと直交する周囲方向に向けても光を放出する機能も有しており、車両の進行方向Fに直交するWの方向からも「印」としての表示が視認できるようになっている。   At the same time, the light emitting portion 3b of each LED 3a has a cylindrical shape, and has a function of emitting light even in the peripheral direction orthogonal to the main optical axis X, and the direction of W orthogonal to the traveling direction F of the vehicle. The display as a “mark” can be visually recognized.

点灯装置9は、照明装置2の光源4であるHID等の放電灯及び各LED3aを商用電源により点灯させるための点灯回路9aを有するとともに、停電時等、商用電源が遮断された場合に、その状態を検知し各LED3aを蓄電池10により点灯させるための検知器を有している。蓄電池10は、ニッケルカドニウム(Ni―Cd)蓄電池、リチウムイオン電池、鉛蓄電池または積層コンデンサ等で構成される。   The lighting device 9 has a discharge lamp such as an HID that is the light source 4 of the lighting device 2 and a lighting circuit 9a for lighting each LED 3a with a commercial power source. It has a detector for detecting the state and lighting each LED 3a by the storage battery 10. The storage battery 10 includes a nickel cadmium (Ni—Cd) storage battery, a lithium ion battery, a lead storage battery, a multilayer capacitor, or the like.

なお、器具本体1の内部へは、防水コネクター等を介して商用電源からの電源線およびアース線が導入され、器具本体1内に収納された照明装置2、点灯装置9等に配線される。   A power supply line and a ground line from a commercial power source are introduced into the interior of the appliance main body 1 through a waterproof connector or the like and wired to the lighting device 2, the lighting device 9, and the like housed in the appliance main body 1.

上記のように構成された、視線誘導表示付照明器具は、高速道路の路肩側及び中央分離帯側の道路Rの側方位置で、車両のドアーミラーやバックミラーへの映り込みを無くし、運転者へのグレアを低減するために、路面からの高さが1m以下、例えば約70cmの高さに設置する。さらに照明装置2の光学系の光軸cが道路の車両進行方向Fに沿い、光透過部1bが道路R側に面するように1〜10mの間隔、例えば5mの等しい間隔で、道路Rの両側若しくは片側に複数台取付けられ、車両の運転者へ道路の線形を促す視線誘導を行うための低位置追跡照明をなすように設置する。   The luminaire with a gaze guidance display configured as described above eliminates the reflection on the vehicle's door mirror and rearview mirror at the side of the road R on the shoulder side of the highway and the median strip side, and driving In order to reduce glare to the person, the height from the road surface is 1 m or less, for example, about 70 cm. Furthermore, the optical axis c of the optical system of the illuminating device 2 is along the vehicle traveling direction F of the road, and the light transmitting portion 1b faces the road R side at an interval of 1 to 10 m, for example, an equal interval of 5 m. A plurality of units are mounted on both sides or one side, and installed so as to provide low-position tracking illumination for guiding the line of sight to promote the alignment of the road to the driver of the vehicle.

なお、器具本体1は、光学系の光軸cが道路の車両進行方向Fに対する道路内方(W方向)への水平角を10〜30度、俯角は0〜5度程度の角度にして設置される。   The instrument body 1 is installed with the optical axis c of the optical system set at a horizontal angle of 10 to 30 degrees in the road (W direction) with respect to the vehicle traveling direction F of the road, and the depression angle is about 0 to 5 degrees. Is done.

次に、上記のように構成され高速道路に設置された視線誘導表示付照明器具の作動につき説明する。   Next, the operation of the lighting apparatus with a gaze guidance display configured as described above and installed on a highway will be described.

まず、商用電源から電力が供給され点灯装置9を介して光源4が点灯され、光源4から反射鏡5に向かう光が反射鏡5で反射されて第二焦点bに集光される。第二焦点を通過した光が凸レンズ7を通じて光軸cに平行な光に屈折され、この平行光が光透過部1bを通じて道路Rの車両進行方向Fへ向けて照射される。この際、反射鏡5やレンズ7で制御しきれない光も反射板8により反射されて道路Rの車両進行方向Fへ放射され、照射効率を向上するようにしている。   First, power is supplied from a commercial power source, the light source 4 is turned on via the lighting device 9, and the light from the light source 4 toward the reflecting mirror 5 is reflected by the reflecting mirror 5 and collected at the second focal point b. The light that has passed through the second focal point is refracted into light parallel to the optical axis c through the convex lens 7, and the parallel light is irradiated toward the vehicle traveling direction F on the road R through the light transmission portion 1b. At this time, light that cannot be controlled by the reflecting mirror 5 and the lens 7 is also reflected by the reflecting plate 8 and radiated in the vehicle traveling direction F on the road R to improve the irradiation efficiency.

これにより、先行する車両、路肩に停止している車両等、さらに道路上の障害物などを後方から直接的に照明して路面輝度を確保することができ、道路Rを進行する車両からは、高機能舗装など路面の反射率が低い場合でも障害物等の存在を確実に視認することができる。   Thereby, it is possible to ensure the road surface brightness by directly illuminating the preceding vehicle, the vehicle stopped on the shoulder of the road, and the obstacles on the road directly from the rear, and from the vehicle traveling on the road R, Even when the reflectance of the road surface is low, such as high-performance pavement, the presence of an obstacle or the like can be reliably recognized.

この際、光軸cは車両進行方向Fに向かっているため、車両の運転者からは器具本体1の存在は確認しにくく、道路Rの線形を促す視線誘導効果が落ちる問題が生じる。   At this time, since the optical axis c is directed in the vehicle traveling direction F, it is difficult for the driver of the vehicle to confirm the presence of the instrument main body 1, and there is a problem that the line-of-sight guidance effect that promotes the alignment of the road R is reduced.

しかし、本実施形態では、上記の障害物等の存在を視認させる路面輝度確保のための照明を行うと同時に、器具本体1に設けられた各LED3aが、照明装置による路面を照明するための大なる光量の光ではなく、表示機能である印として、その存在自体を表示する程度の光量で表示し、しかも、その表示は車両進行方向Fに反する方向に向かっているため、道路を進行する車両の運転手からは、「縦に3個の点」、遠方からは「連続した縦線」の印として視認することができる。   However, in the present embodiment, the illumination for ensuring the road surface brightness for visually recognizing the presence of the obstacles and the like is performed, and at the same time, each LED 3a provided in the fixture body 1 is a large light source for illuminating the road surface by the illumination device. Vehicle that travels on the road because it is displayed with a light quantity that is sufficient to display its presence as a mark that is a display function instead of a light quantity that becomes a display function. From the driver, it can be visually recognized as “three vertical points” and from a distance as “continuous vertical lines”.

この際、LEDの光量は、その存在自体を表示する程度の光量で表示するため、グレアの発生が防止でき、運転者には眩しく写らず「まぶしさ」を感じさせないようにして道路Rの線形を促す視線誘導を確実に行うことができる。   At this time, since the light quantity of the LED is displayed with a light quantity that displays the presence of the LED itself, the occurrence of glare can be prevented, and the driver does not appear dazzling and does not feel “glare”. It is possible to surely guide the line of sight for prompting.

なお、各LED3aの発光部3bは円筒状をなしており周囲方向に向けても光って表示するので、車両の進行に伴い、設置された器具本体1の横を車両が通過するまで、連続的に「印」としての表示を視認することができる。   In addition, since the light emission part 3b of each LED3a has comprised the cylinder shape and it shines and displays also toward the circumference direction, it continues until the vehicle passes the side of the installed instrument main body 1 with the progress of the vehicle. The display as “mark” can be visually recognized.

次に、停電時などで商用電源が遮断された場合、点灯装置9に内蔵されている検知器により、商用電源が遮断された状態を検知して自動的に非常用電源である蓄電池10に切り替え、各LED3aが、蓄電池10から点灯装置9を介して電池電源が供給され、非常時動作時間(約10分)以上点灯し、停電時における視線誘導を行う。   Next, when the commercial power supply is interrupted due to a power failure or the like, the detector built in the lighting device 9 detects the state where the commercial power supply is shut off and automatically switches to the storage battery 10 as an emergency power source. Each of the LEDs 3a is supplied with battery power from the storage battery 10 via the lighting device 9, and is lit for an emergency operation time (about 10 minutes) or more, and performs line-of-sight guidance during a power failure.

停電が復帰すれば、点灯装置9の検知器が商用電源の復帰状態を検知して、上述したと同様に商用電源で照明装置2による障害物等の存在を視認させる路面輝度確保のための照明を行うと同時に各LED3aの表示による視線誘導を行う。   When the power failure is restored, the detector for the lighting device 9 detects the return state of the commercial power source, and the illumination for ensuring the road surface brightness that allows the commercial power source to visually recognize the presence of an obstacle or the like as described above. At the same time, the line of sight is guided by the display of each LED 3a.

以上本実施形態では、各LED3aを器具本体1の端部の凹部1fに傾斜して設けられた支持部1gに、その発光部3bが外面に露出するように位置させて設けたが、各LED3aに加えて図4に示すように器具本体1の車両進行方向Fと反する方向の側面1hに、縦一列に等間隔に3個のLED3cを取付けるようにしても、さらに図4に破線で示すように器具本体1の正面板1aの左方下面に横一列に3個のLED3dを設けて、遠方からは「連続した横線」を表示するようにしてもよい。   As described above, in the present embodiment, each LED 3a is provided on the support portion 1g provided to be inclined in the concave portion 1f at the end of the instrument body 1 so that the light emitting portion 3b is exposed on the outer surface. In addition to this, as shown in FIG. 4, even if three LEDs 3c are mounted on the side surface 1h of the appliance body 1 in the direction opposite to the vehicle traveling direction F at equal intervals in a vertical row, it is further indicated by broken lines in FIG. Alternatively, three LEDs 3d may be provided in a horizontal row on the lower left side of the front plate 1a of the instrument body 1 so that a “continuous horizontal line” is displayed from a distance.

また、支持部1gのLED3aは省略し、側面1hにのみ3個のLED3cを設けるようにしてもよい。   Further, the LED 3a of the support portion 1g may be omitted, and the three LEDs 3c may be provided only on the side surface 1h.

さらに、支持部1gのLED3aは省略し、上記の側面1hと、正面板1aの両面にそれぞれ3個のLED3c、3dを設けて、車両の進行に伴い、設置された器具本体1の横を車両が通過するまで、側面から正面にわたり連続的に「印」としての表示を視認できるようにしてもよい。   Further, the LED 3a of the support portion 1g is omitted, and three LEDs 3c and 3d are provided on the side surface 1h and both surfaces of the front plate 1a, respectively. It may be made possible to visually recognize the display as “mark” from the side surface to the front surface until it passes.

LEDによる光量の調整は、使用するLEDの仕様、性能を適宜選択することによっても、または使用する個数を選択するようにして、その存在自体を表示する程度の光量に調整するようにすればよい。   The adjustment of the amount of light by the LED may be performed by appropriately selecting the specification and performance of the LED to be used, or by selecting the number to be used and adjusting the amount of light so that the presence itself is displayed. .

また、LED自体での調整が困難なときなどには、各LED3aの支持部1gを含めた凹部1fの周辺を、反射機能を有するようにして光量不足を補うように構成しても、また光量が多くなりグレアの発生要因になるようなときには、凹部1fの周辺に黒色塗装等を施して光量を抑制するようにしてもよい。   Further, when it is difficult to adjust the LED itself, the periphery of the recess 1f including the support portion 1g of each LED 3a may be configured to have a reflection function so as to compensate for the insufficient light amount. When the amount of light increases and causes glare, black coating or the like may be applied around the recess 1f to suppress the amount of light.

各LED3aは、白色で構成したが、赤、青、黄色等の他の色にしてもよく、またこれら各種の色を混合して配置しても、さらには各LEDを点滅させるようにして表示するようにしてもよい。   Each LED 3a is configured in white, but may be other colors such as red, blue, yellow, etc. Even if these various colors are mixed and arranged, each LED is blinked and displayed. You may make it do.

停電時に、蓄電池10によりLEDによる視線誘導のみを行うようにしたが、同時に照明装置2による障害物等の存在を視認させる路面輝度確保のための照明も行うようにしてもよい。   At the time of a power failure, only the line-of-sight guidance by the LED is performed by the storage battery 10, but at the same time, the illumination device 2 may also perform illumination for ensuring the road surface brightness so as to visually recognize the presence of an obstacle or the like.

本実施形態では、高速道路に設置したが通常の自動車道路、さらにはトンネル用照明器具として設置してもよい。   In this embodiment, although it installed in the expressway, you may install as a normal motorway and also as a lighting fixture for tunnels.

本実施形態によれば、照明装置により、先行する車両、路肩に停止している車両等、さらに道路上の障害物などを後方から直接的に照明し路面輝度を確保することができ、高機能舗装等、路面の反射率が低い場合でも障害物等の存在を確実に視認することができる。   According to the present embodiment, the lighting device can directly illuminate a preceding vehicle, a vehicle stopped on the shoulder of a road, an obstacle on the road, or the like directly from the rear, thereby ensuring high road performance. Even when the reflectance of the road surface is low, such as on pavement, the presence of an obstacle or the like can be reliably recognized.

さらに、LEDにより表示機能である印を視認できる程度の光量で表示することができ、運転者に眩しく写るグレアの発生を防ぎ、「まぶしさ」を感じさせないようにして道路の線形を促す視線誘導を行うことが可能となる。   In addition, the LED can display a sign that is a display function with a light amount that can be visually recognized, prevents glare from being dazzled by the driver, and promotes the alignment of the road without feeling “glare” Can be performed.

さらに、LEDにより表示機能である印を視認できる程度の光量を容易に設定することができると共に、省電力で長寿命な視線誘導表示付照明器具を提供することができる。   Furthermore, it is possible to easily set an amount of light that allows the LED, which is a display function, to be visually recognized by the LED, and to provide a lighting device with a gaze guidance display that saves power and has a long life.

また、視線誘導を行うために、照明装置2の反射板8に白色のテープを貼り、その反射光で視線誘導の表示を行う手段もあるが、この手段は、照明装置の路面輝度を確保するための光源の光を利用して表示するために、本来行うべき路面輝度確保のための光を反射板に貼りつけた白色テープで乱反射させてしまい、光源の主光軸の光量が低下し、また漏れ光が多くなりグレア発生の原因にもなってしまう問題が生じる。これに対し、本実施形態では、照明装置2の反射板8には何も付すことなく視線誘導を行うため、路面輝度を確保するための照明装置の光学性能を損ねたり、グレアを発生したりすることなく、運転者への視線誘導効果を向上させることが可能となる。   In addition, in order to perform the line-of-sight guidance, there is a means for attaching a white tape to the reflecting plate 8 of the lighting device 2 and displaying the line-of-sight guidance with the reflected light. This means secures the road surface brightness of the lighting device. In order to display using the light of the light source for the purpose, the light for securing the road surface brightness to be originally performed is diffusely reflected by the white tape attached to the reflecting plate, the light quantity of the main optical axis of the light source is reduced, In addition, there is a problem in that the amount of leaked light increases and causes glare. On the other hand, in the present embodiment, the line of sight is guided without attaching anything to the reflector 8 of the lighting device 2, so that the optical performance of the lighting device for ensuring the road surface brightness is impaired, or glare is generated. Thus, it is possible to improve the effect of guiding the line of sight to the driver.

図5は本発明の第二の実施形態である視線誘導表示付照明器具を示す斜視図、図6は同じく視線誘導表示付照明器具の変形例を示す斜視図で、各図には第一の実施形態と同一部分に同一符号を付してある。   FIG. 5 is a perspective view showing a lighting apparatus with a gaze guidance display according to the second embodiment of the present invention. FIG. 6 is a perspective view showing a modification of the lighting apparatus with a gaze guidance display. The same parts as those in the embodiment are denoted by the same reference numerals.

本実施形態の視線誘導表示付照明器具は、第一の実施形態におけるLEDに代えて、蓄光性能を有する反射テープで表示部材を構成したものである。   The luminaire with a line-of-sight guidance display of the present embodiment is configured by configuring a display member with a reflective tape having phosphorescent performance instead of the LED in the first embodiment.

すなわち、図中10は器具本体1における反射板8の反射面8aに貼付された蓄光性能を有する反射テープで、反射テープ10は長方形の短冊状をなし、反射板8の車両進行方向F寄りに、テープの長手方向が車両進行方向Fに沿うように貼付されている。   That is, in the figure, reference numeral 10 denotes a reflecting tape having a phosphorescent performance affixed to the reflecting surface 8a of the reflecting plate 8 in the instrument body 1. The reflecting tape 10 has a rectangular strip shape and is closer to the vehicle traveling direction F of the reflecting plate 8. The tape is attached so that the longitudinal direction of the tape is along the vehicle traveling direction F.

反射テープ10は、白色のビニールテープの表面に蛍光体等の蓄光性能を有する成分を含有する塗料を塗布して構成しても、または白色ビニールテープを形成する際に蓄光性能を有する成分を含有させて構成するようにしてもよい。   The reflective tape 10 is configured by applying a paint containing a component having a phosphorescent performance such as a phosphor on the surface of a white vinyl tape, or contains a component having a phosphorescent performance when forming a white vinyl tape. You may make it comprise.

なお、本実施形態の場合は、表示部材として電源を必要としない蓄光性能を有する反射テープで構成しているために、停電時等に表示部材を作動させるための蓄電池、点灯装置等の設置はしていない。   In the case of this embodiment, since the display member is composed of a reflective tape having a phosphorescent performance that does not require a power source, installation of a storage battery, a lighting device, etc. for operating the display member at the time of a power failure, etc. Not done.

その他の構成は、第一の実施形態と同様に構成されている。   Other configurations are the same as those in the first embodiment.

上記のように構成された視線誘導表示付照明器具は、第一の実施形態と同様に高速道路の路肩側及び中央分離帯側の道路Rの側方位置に取付けられ、視線誘導を行うための低位置追跡照明をなすように設置され、照明装置2の光源4が点灯され、光透過部1bを通じて道路Rの車両進行方向Fへ向けて照射し路面輝度を確保するための照明を行う。   The luminaire with a gaze guidance display configured as described above is attached to the side position of the road R on the shoulder side of the expressway and the median strip as in the first embodiment, and performs gaze guidance. The light source 4 of the illuminating device 2 is installed so as to perform low-position tracking illumination, and illuminates in the vehicle traveling direction F of the road R through the light transmission part 1b to perform illumination for ensuring road surface brightness.

さらに、器具本体1の反射板8に貼付された蓄光性能を有する反射テープ10が表示機能である印として、その存在自体を表示する程度の光量で表示し、しかも、その表示は車両進行方向Fに反する方向に向かっているため、道路を進行する車両の運転手からは、「横線」の印として視認することができる。   Further, the reflective tape 10 having a phosphorescent performance affixed to the reflection plate 8 of the instrument body 1 is displayed as a mark indicating the display function with a light quantity that displays the presence itself, and the display is the vehicle traveling direction F. Therefore, it can be visually recognized as a “horizontal line” from the driver of the vehicle traveling on the road.

この際、蓄光性能を有する反射テープ10の光量は、その存在自体を表示する程度の光量で表示するため、グレアの発生が防止でき、運転者には眩しく写らず「まぶしさ」を感じさせないようにして道路Rの線形を促す視線誘導を確実に行うことができる。   At this time, since the light quantity of the reflective tape 10 having phosphorescent performance is displayed with a light quantity that displays the presence itself, the occurrence of glare can be prevented and the driver is not dazzled and does not feel “glare”. Thus, it is possible to reliably perform line-of-sight guidance that promotes alignment of the road R.

停電時などで、万一商用電源が遮断された場合でも、蓄光性能を有する反射テープ10の残光により、その存在を表示して視線誘導効果を確保することができる。   Even if the commercial power supply is cut off due to a power failure or the like, the presence of the reflection tape 10 having the phosphorescent performance can be displayed by the presence of the afterglow to ensure the gaze guidance effect.

なお、蓄光性能を有する反射テープ10への蓄光は、昼間の太陽光線がテープに照射されることや、トンネル内等、太陽光線が届かない場所では照明装置2の光源4からの光が反射板8に貼付された反射テープ10を照射して光を蓄光することができる。   In addition, the light storage on the reflective tape 10 having the light storage performance is such that the light from the light source 4 of the illuminating device 2 is reflected on the tape when sunlight is irradiated on the tape in a daytime or in a place where the sunlight does not reach such as in a tunnel. Light can be stored by irradiating the reflective tape 10 affixed to 8.

以上本実施形態では、蓄光性能を有する反射テープ10を器具本体1における反射板8の反射面8aに貼付したが、これに加え図6に示すように器具本体1の車両進行方向Fと反する方向の側面1hに反射テープ10aを縦に貼付して表示しても、さらに図6に破線で示すように、器具本体1の正面板1aの左方下面に横に反射テープ10b貼付して表示するようにしてもよい。   As described above, in the present embodiment, the reflective tape 10 having phosphorescent performance is attached to the reflecting surface 8a of the reflecting plate 8 in the instrument body 1, but in addition to this, the direction opposite to the vehicle traveling direction F of the instrument body 1 as shown in FIG. Even if the reflection tape 10a is vertically attached to the side surface 1h of the display, the reflection tape 10b is attached to the left lower surface of the front plate 1a of the instrument body 1 as shown by the broken line in FIG. You may do it.

また、反射面8aの反射テープ10は省略し、側面1hにのみ反射テープ10aを設けるようにしてもよい。   The reflective tape 10 on the reflective surface 8a may be omitted, and the reflective tape 10a may be provided only on the side surface 1h.

さらに、反射面8aの反射テープ10は省略し、上記の側面1hと、正面板1aの両面にそれぞれ反射テープ10a、10bを設けて、車両の進行に伴い、設置された器具本体1の横を車両が通過するまで、側面から正面にわたり連続的に「印」としての表示を視認できるようにしてもよい。   Further, the reflective tape 10 on the reflective surface 8a is omitted, and reflective tapes 10a and 10b are provided on both the side surface 1h and the front plate 1a, respectively. Until the vehicle passes, the display as “mark” may be made visible from the side to the front.

蓄光性能を有する反射テープ10による光量の調整は、蛍光体等の蓄光性能を有する成分の性能を適宜選択することによっても、またはテープの大きさ、形状、使用する個数を選択するようにして、その存在自体を表示する程度の光量に調整するようにすればよい。   The adjustment of the amount of light by the reflective tape 10 having a phosphorescent performance is performed by appropriately selecting the performance of a component having a phosphorescent performance, such as a phosphor, or by selecting the size, shape, and number of tapes to be used, The amount of light may be adjusted to a level that displays the presence itself.

蓄光性能を有する反射テープ10は、白色で構成したが、赤、青、黄色等の他の色にしてもよく、またこれら各種の色を混合して配置してもよい。   The reflective tape 10 having the luminous performance is configured in white, but may be other colors such as red, blue, and yellow, or a mixture of these various colors.

路面輝度確保のための照明装置2を停電時等に作動させるために蓄電池、点灯装置等を設置して、停電時に、蓄光性能を有する反射テープ10の残光による視線誘導を行う共に、照明装置2による障害物等の存在を視認させる路面輝度確保のための照明も同時に行うようにしてもよい。   A storage battery, a lighting device, and the like are installed in order to operate the lighting device 2 for ensuring road surface brightness at the time of a power failure, etc., and at the time of a power failure, the line of sight is guided by the afterglow of the reflective tape 10 having a light storage performance. Illumination for ensuring road surface brightness for visually confirming the presence of an obstacle or the like by 2 may be performed simultaneously.

本実施形態によれば、蓄光性能を有する反射テープにより表示機能である印を視認できる程度の光量を、単にテープを貼付するなどの簡易な手段で設定することができると共に、非常用電源である蓄電池等の設置が不要となり、コスト的にも有利な視線誘導表示付照明器具を提供することができる。   According to the present embodiment, the amount of light that can be visually recognized by the reflective tape having phosphorescent performance can be set by simple means such as simply attaching the tape, and is an emergency power source. Installation of a storage battery or the like is unnecessary, and a lighting apparatus with a visual line guidance display that is advantageous in terms of cost can be provided.

その他の構成・作用・変形例、作用効果等は、第一の実施形態と同様である。   Other configurations, functions, modifications, functions and effects are the same as those in the first embodiment.

本実施形態の視線誘導表示付照明器具は、第一の実施形態におけるLEDに代えて、光を車両進行方向に向けて照射する路面輝度確保用の照明装置における照明用の光のうち、光学系の焦点に集光しきらない程度の微量の光を利用して表示部材を構成したものである。   The lighting apparatus with a line-of-sight guidance display of the present embodiment is an optical system out of the illumination light in the illumination device for securing road surface brightness that irradiates light in the vehicle traveling direction instead of the LED in the first embodiment. The display member is configured using a very small amount of light that cannot be condensed at the focal point.

すなわち、図中20は第一実施形態の照明装置2における第二の焦点bの下方に位置して配置された光の角度変換手段であるプリズムレンズで、第二焦点bに集光しきらない光Yを、プリズムの角度変換作用により所定の方向、本実施形態では図7中の下方に向かわせる。   That is, in the figure, reference numeral 20 denotes a prism lens which is an angle conversion means of light disposed below the second focal point b in the illuminating device 2 of the first embodiment and does not fully converge on the second focal point b. The light Y is directed in a predetermined direction, in this embodiment, downward in FIG. 7 by the prism angle conversion action.

21は光ファイバよりなる光伝播手段で、プリズムレンズ20で方向が変換された光Yを、一端から入光させ所定の表示部分である光の出射端に伝播させるものである。   Reference numeral 21 denotes a light propagation means made of an optical fiber for entering the light Y whose direction has been changed by the prism lens 20 from one end and propagating it to the light emitting end which is a predetermined display portion.

本実施形態では、図8に示すように器具本体1の車両進行方向Fと反する方向の側面1hに、縦に3個の出射端21aを露出させ、さらに正面板1aの左方下面に横に3個の出射端21bを露出させて表示部材を構成している。   In the present embodiment, as shown in FIG. 8, on the side surface 1h of the instrument body 1 in the direction opposite to the vehicle traveling direction F, the three emission ends 21a are exposed vertically, and further horizontally on the lower left side of the front plate 1a. The display member is configured by exposing the three emission ends 21b.

光の角度変換手段であるプリズムレンズ20および光伝播手段である光ファイバ21は、反射鏡で構成して光の角度変換および伝播を行うようにしてもよい。   The prism lens 20 that is the light angle conversion means and the optical fiber 21 that is the light propagation means may be configured by a reflecting mirror to perform light angle conversion and propagation.

なお、本実施形態の場合は、停電時等に表示部材を作動させるため蓄電池、点灯装置等を設置する。   In the case of the present embodiment, a storage battery, a lighting device, and the like are installed to operate the display member at the time of a power failure or the like.

その他の構成は、第一、第二の実施形態と同様に構成されている。   Other configurations are the same as those in the first and second embodiments.

上記のように構成された視線誘導表示付照明器具は、第一、第二の実施形態と同様に高速道路の路肩側及び中央分離帯側の道路Rの側方位置に取付けられ、視線誘導を行うための低位置追跡照明をなすように設置され、照明装置2の光源4が点灯され、光透過部1bを通じて道路Rの車両進行方向Fへ向けて照射し路面輝度を確保するための照明を行う。   The luminaire with a gaze guidance display configured as described above is attached to a side position of the road R on the shoulder side of the expressway and the median strip as in the first and second embodiments, and guides the gaze. The light source 4 of the illuminating device 2 is installed so as to perform low-position tracking illumination for performing, and illumination for ensuring road surface brightness by irradiating in the vehicle traveling direction F of the road R through the light transmitting portion 1b. Do.

さらに、第二焦点bに集光しきらない光Yを、プリズムレンズ20で、角度を変換させて光ファイバ21に向かわせるようにし、器具本体1の車両進行方向Fと反する方向の側面1hおよび正面板1aの出射端21a、21bに伝播させ、表示機能である印として、その存在自体を表示する程度の光量で表示し、しかも、その表示は車両進行方向Fに反する方向に向かっているため、道路を進行する車両の運転手からは、「3個の点」、遠方からは「縦線」と「横線」の印として視認することができる。   Further, the light Y that cannot be collected at the second focal point b is converted by the prism lens 20 toward the optical fiber 21 by changing the angle, and the side surface 1h in the direction opposite to the vehicle traveling direction F of the instrument body 1 and Because it propagates to the emission ends 21a and 21b of the front plate 1a and is displayed as a display function mark with an amount of light that displays the presence itself, and the display is directed in a direction opposite to the vehicle traveling direction F. From the driver of the vehicle traveling on the road, it can be visually recognized as “three points” and from a distance as “vertical line” and “horizontal line”.

この際、光ファイバ21から放出される光の光量は、路面輝度確保用の照明装置2における照明用の光のうち、第二焦点bに集光しきらない程度の微量の光Yを利用してその存在自体を表示する程度の光量で表示するため、グレアの発生が防止でき、運転者には眩しく写らず「まぶしさ」を感じさせないようにして道路Rの線形を促す視線誘導を確実に行うことができる。   At this time, the amount of light emitted from the optical fiber 21 is a very small amount of light Y that is not collected at the second focal point b out of the illumination light in the illumination device 2 for ensuring road surface brightness. The presence of the display itself is displayed with a light quantity that can be displayed, so that glare can be prevented and the driver is not dazzled and does not feel “glare”. It can be carried out.

停電時などで、万一商用電源が遮断された場合には、停電の検知器、蓄電池、点灯装置等が作動して、路面輝度確保のための照明装置2が作動するため、照明装置2による障害物等の存在を視認させる路面輝度確保のための照明と同時に視線誘導も行うことができる。   If the commercial power supply is interrupted due to a power failure, the power failure detector, storage battery, lighting device, etc. are activated, and the lighting device 2 for ensuring the road surface brightness is activated. Gaze guidance can be performed simultaneously with illumination for ensuring road surface brightness to visually recognize the presence of an obstacle or the like.

また、路面輝度確保のための照明装置2としては、グレアの発生源となる第二焦点bに集光しきらない光Yを、遮光手段6により遮光して器具効率が悪くなる問題があるが、本実施形態によれば、第二焦点bに集光しきらない光Yを、遮光手段6により遮光せずに、プリズムレンズ20で角度を変換させて光ファイバ21に向かわせて視線誘導を行うための光源として有効に利用する。この結果、照明装置2としての器具効率が向上すると共に、グレアの発生源となる第二焦点bに集光しきらない光Yを、光透過部1bから放射しないので、路面輝度確保のための照明装置2においてもグレアの発生を防止することができる。   In addition, the illumination device 2 for ensuring the road surface brightness has a problem that the light Y that cannot be collected at the second focal point b, which is the generation source of glare, is shielded by the light shielding means 6 so that the appliance efficiency is deteriorated. According to the present embodiment, the light Y that is not collected at the second focal point b is not shielded by the light shielding means 6, but the angle is converted by the prism lens 20 and directed toward the optical fiber 21 to guide the line of sight. It is used effectively as a light source for performing. As a result, the efficiency of the appliance as the illuminating device 2 is improved, and the light Y that cannot be collected at the second focal point b, which is the generation source of glare, is not emitted from the light transmitting portion 1b. Generation of glare can also be prevented in the illumination device 2.

以上本実施形態では、光ファイバの出射端21a、21bを器具本体の側面1hおよび正面板1aの両面に伝播させ表示するようにしたが、いずれか一方の面にのみ光ファイバの出射端を設け表示するようにしてもよい。   As described above, in the present embodiment, the output ends 21a and 21b of the optical fiber are propagated and displayed on both the side surface 1h and the front plate 1a of the instrument body, but the output end of the optical fiber is provided only on one of the surfaces. You may make it display.

光ファイバの出射端から放出される光の光量の調整は、プリズムレンズや光ファイバ等の光学系の性能を適宜選択することによって、その存在自体を表示する程度の光量に調整するようにすればよい。   The amount of light emitted from the exit end of the optical fiber can be adjusted by appropriately selecting the performance of an optical system such as a prism lens or an optical fiber so that the presence itself can be displayed. Good.

本実施形態によれば、視線誘導を行うための表示機能である印を視認できる程度の光量を、路面輝度確保用の照明装置における照明用の光のうち、焦点に集光しきらない程度の微量の光を利用して設定することができ、格別に視線誘導を行うための光源を備える必要がなくなるので、コスト的にも有利な視線誘導表示付照明器具を提供することができる。   According to the present embodiment, the amount of light that can be used to visually recognize the mark that is a display function for performing line-of-sight guidance is such that it cannot be collected at the focal point in the illumination light in the illumination device for ensuring road surface brightness. Since it is possible to set using a very small amount of light and it is not necessary to provide a light source for specially guiding the line of sight, it is possible to provide a lighting apparatus with a line of sight guidance display that is advantageous in terms of cost.

その他の構成・作用・変形例、作用効果等は、第一、第二の実施形態と同様である。   Other configurations, functions, modifications, functions and effects are the same as those in the first and second embodiments.

さらに、本発明において、視線誘導を行うための表示部材として、上記第一の実施形態におけるLEDによる手段と、第二の実施形態における蓄光性能を有する反射テープによる手段と、さらには第三の実施形態における路面輝度確保用の照明装置における照明用の光のうち、光学系の焦点に集光しきらない程度の微量の光を利用する手段の内、それぞれの手段、若しくはいずれか2つの手段を組み合わせて構成し、視認性をさらに高めるようにしてもよい。   Further, in the present invention, as a display member for performing line-of-sight guidance, the means by the LED in the first embodiment, the means by the reflective tape having the phosphorescent performance in the second embodiment, and the third embodiment Of the light for illumination in the illumination device for ensuring road surface brightness in the form, each means, or any two of the means using a very small amount of light that cannot be condensed at the focal point of the optical system, It may be configured in combination to further improve the visibility.

以上、本発明の好適な実施形態を説明したが、本発明は上述の実施形態に限定されることなく、本発明の要旨を逸脱しない範囲内において、種々の設計変更を行うことができる。   The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and various design changes can be made without departing from the scope of the present invention.
