Description

照明裝置及用於該裝置的集光體 Lighting device and light collector for the same

本發明,是關於一種使用例如LED(發光二極體)作為光源的聚光燈等的照明裝置及用於該裝置的集光體,尤其是關於一種,使來自光源的光的集光效果提昇的照明裝置及用於該裝置的集光體。 The present invention relates to an illumination device using a spotlight such as an LED (Light Emitting Diode) as a light source, and a light collector for the same, and more particularly to an illumination for improving the light collection effect of light from a light source A device and a light collector for the device.

以聚光燈等的照明裝置的光源來說,因為對環境的關懷、低消耗電力化,而愈來愈常使用LED取代以往的螢光燈、白熾燈。聚光燈是可對比較狹窄的範圍或被限定的範圍集中進行照射為理想。然而,LED因為具有光的射出角大且廣闊的配光分布,所以照明光容易在廣大範圍擴散。因此,在使用LED的照明裝置,構成以透鏡體等將來自LED的光予以集光。 In the light source of a lighting device such as a spotlight, LEDs have been used more and more frequently to replace conventional fluorescent lamps and incandescent lamps because of environmental care and low power consumption. Spotlights are ideal for concentrating a relatively narrow range or a limited range of exposures. However, since the LED has a large emission angle of light and a wide distribution of light distribution, the illumination light is easily diffused over a wide range. Therefore, in an illumination device using an LED, light from an LED is collected by a lens body or the like.

作為將來自LED的光予以集光用的習知技術,已知有例如記載於專利文獻1者。在專利文獻1揭示有,具有LED等的光源與透鏡體,該透鏡體是由:形成在該透鏡體中央,藉由折射來自光源的預定角度範圍內的光而予以聚集的中央稜鏡部;以及設置成在該中央稜鏡部的周圍形成凹部的外環稜鏡部,讓從光源射出的光線在透鏡體的中央部稜鏡部折射而予以聚集,而使射入到外環稜鏡部的內部的光線在外環稜鏡的界面全反射而予以聚集。又,在專利文獻1的圖4,揭示有為了使來自光源的光更聚集,而將 透鏡體的外環稜鏡(凸狀曲面部)作成拋物線面或橢圓面。 As a conventional technique for collecting light from an LED, for example, it is described in Patent Document 1. Patent Document 1 discloses a light source having a LED or the like and a lens body formed by a central crotch portion formed at a center of the lens body and condensed by light in a predetermined angle range from the light source; And an outer ring portion formed to form a concave portion around the central crotch portion, and the light emitted from the light source is refracted at the central portion of the lens body to be collected, and is incident on the outer ring portion The internal light is totally reflected at the interface of the outer ring to gather. Further, in FIG. 4 of Patent Document 1, it is revealed that in order to concentrate light from a light source, The outer ring 稜鏡 (convex curved surface portion) of the lens body is formed as a parabolic surface or an elliptical surface.

[專利文獻1]日本特開2002-43629號公報 [Patent Document 1] Japanese Patent Laid-Open Publication No. 2002-43629

記載於上述專利文獻1的外環稜鏡的形狀雖然用來使從光源所射出的光線聚集有效,可是專利文獻1,因為透鏡體的射出面為平面狀,所以即使在外環稜鏡將光予以集光,也容易在射出面折射、擴散。因此,在專利文獻1,要獲得良好的集光效果變得困難。 The shape of the outer ring of the above-described Patent Document 1 is effective for collecting the light emitted from the light source. However, in Patent Document 1, since the exit surface of the lens body is planar, even in the outer ring, the light is emitted. It is easy to collect light and is easy to refract and diffuse on the exit surface. Therefore, in Patent Document 1, it becomes difficult to obtain a good light collecting effect.

本發明是有鑑於上述習知技術的課題所研發者,在照明裝置,提供一種提昇來自光源的光的集光效果,而使來自照明裝置的照射光的明亮度提昇適宜的技術。 The present invention has been developed in view of the above-described problems of the prior art, and provides a technique for improving the brightness of the illumination light from the illumination device by improving the light collecting effect of the light from the light source in the illumination device.

本發明是以記載於申請專利範圍的構造作為特徵者。更具體而言,本發明的照明裝置,是具備:光源;以及由透明的材質所形成之用來將來自前述光源的光予以集光並射出的集光體,且為:在前述集光體的光射出側的端部設有以朝向來自前述光源的光的入射側彎曲的方式被形成的彎曲射出面,與前述集光體的中心軸正交的方向的寬幅尺寸從前述光入射側朝向前述光射出面變大,在前述集光體 的側面前述中心軸平行的剖面成為橢圓的一部分,且在該側面設有反射面。此時,使前述彎曲射出面的焦點、與前述橢圓形狀的反射面的焦點形成大致一致為理想。 The present invention is characterized by the structure described in the patent application. More specifically, the illumination device of the present invention includes: a light source; and a light concentrator formed of a transparent material for collecting and emitting light from the light source, and the concentrator The end portion on the light-emitting side is provided with a curved exit surface formed to be curved toward the incident side of the light from the light source, and a wide dimension in a direction orthogonal to the central axis of the light-collecting body is from the light incident side. The light-emitting surface becomes larger toward the aforementioned light-emitting surface The side surface parallel to the central axis is a part of the ellipse, and a reflecting surface is provided on the side. In this case, it is preferable that the focus of the curved exit surface is substantially the same as the focus of the elliptical reflecting surface.

根據上述本發明的構造,由於可將來自光源(LED)的光更適宜地予以集光,所以可使來自照明裝置的照射光的明亮度提昇。 According to the configuration of the present invention described above, since the light from the light source (LED) can be more appropriately collected, the brightness of the illumination light from the illumination device can be improved.

Illustration of the light source substrate 10 and the support member 11.

光源1是例如使用LED,朝向被配置在其上的集光體2(朝向紙面上方)放出光。在本實施例,以光源1來說是使用例如放出白色光的白色LED者。白色LED是具有:例如接收電力發出青色光的發光晶片部分;以及接收來自該發光晶片的青色光被激發,而發出具有由綠到紅的波長區域的光譜的光的螢光體。以該螢光體來說,也可使用同時激發紅與綠的光,而具有看起來像黃色的發光光譜的螢光體。再者,在一個LED也可利用利用了複數個發光晶片的大光量類型的LED。在利用複數個發光晶片的LED,雖以LED的發光面(光放出面)的中心為基準,以對稱方式將發光晶片例如配置成矩形狀、同心圓狀為理想,可是配置並不限於此。 The light source 1 emits light toward the light concentrating body 2 (above the paper surface) disposed thereon, for example, using an LED. In the present embodiment, for the light source 1, for example, a white LED that emits white light is used. The white LED is a phosphor having a light-emitting chip portion that emits cyan light, for example, and a phosphor that receives cyan light from the light-emitting wafer and emits light having a spectrum of a wavelength region from green to red. In the case of the phosphor, it is also possible to use a phosphor that simultaneously excites red and green light, and has a luminescence spectrum that looks like yellow. Further, a large-quantity type LED using a plurality of light-emitting chips can be utilized for one LED. In the LED using a plurality of light-emitting chips, it is preferable that the light-emitting chips are arranged in a rectangular shape or a concentric shape in a symmetrical manner with respect to the center of the light-emitting surface (light-emitting surface) of the LED, but the arrangement is not limited thereto.

又,在光源1,也可具備改善配光的調整、光的取出的效率用的透鏡、反射器等的光學零件。以這樣的光學零件來說,例如可使用由具透過性的材質所成形的凸透鏡、被金屬蒸鍍的鏡子等。 Further, the light source 1 may include an optical component such as a lens or a reflector for improving the adjustment of the light distribution and the efficiency of extracting the light. For such an optical component, for example, a convex lens formed of a material having transparency, a mirror vapor-deposited by metal, or the like can be used.

光源1是被實際安裝在光源基板10。圖中,在光源基板10上雖只實際安裝1個光源1,可是為了增加光量也可實際安裝複數個光源。又光源基板10除了光源1之外, 也設有將來自未圖示的電源的電力供給到光源1用的驅動電路(驅動器)、配線及/或控制對光源1的電力供給量(電流量)用的控制電路等的電子零件、電路。該等電子零件、電路也可設在與光源基板10的光源1的實際安裝面相反側的面。 The light source 1 is actually mounted on the light source substrate 10. In the figure, although only one light source 1 is actually mounted on the light source substrate 10, a plurality of light sources may be actually mounted in order to increase the amount of light. In addition to the light source 1, the light source substrate 10 It is also provided with a drive circuit (driver) for supplying electric power from a power source (not shown) to a light source 1 , a wiring, and/or a control circuit for controlling a power supply amount (current amount) to the light source 1 , and the like. . These electronic components and circuits may be provided on the surface opposite to the actual mounting surface of the light source 1 of the light source substrate 10.

在光源1的光放出側配置有由透明樹脂等的透明材質所形成的實心的集光體2。以集光體2的材質來說,可利用具有玻璃、塑膠等的光透過性的材質。例如,舉生產性優的塑膠為例時,可利用聚碳酸酯、壓克力等。以製造集光體的方法來說,例如可利用加熱材料提高流動性澆注到模具,使其冷卻凝固成型的射出成形。此時,模具的表面是如後述被研磨為理想。 A solid light concentrating body 2 made of a transparent material such as a transparent resin is disposed on the light emitting side of the light source 1. As the material of the light collector 2, a material having light transmittance such as glass or plastic can be used. For example, in the case of a plastic which is excellent in productivity, polycarbonate, acrylic, or the like can be used. In the method of producing a light-collecting body, for example, a heating material can be used to increase fluidity and cast into a mold to form a cooling and solidification injection molding. At this time, the surface of the mold is preferably polished as described later.

圖中的點線表示集光體2的中心軸CX,光源1為1個LED時,以中心軸CX與LED的光軸幾乎一致的方式進行光源1與集光體2的對位。又,光源1是由2次元實際安裝在光源基板10上的複數個LED所構成時,以從光射出側看到光源1時的配光分布的中心與中心軸CX幾乎一致的方式進行光源1與集光體2的對位。 The dotted line in the figure indicates the central axis CX of the light-collecting body 2, and when the light source 1 is one LED, the alignment of the light source 1 and the light-collecting body 2 is performed such that the central axis CX and the optical axis of the LED substantially coincide. When the light source 1 is composed of a plurality of LEDs that are actually mounted on the light source substrate 10 in the second dimension, the light source 1 is configured such that the center of the light distribution when the light source 1 is seen from the light exit side substantially coincides with the central axis CX. Alignment with the collector 2.

集光體2,是構成在其一端入射來自光源1的光,一面將這個予以集光一面從另一端將光予以射出。而且集光體2與中心軸CX(以點線圖示)正交的剖面為圓形,其剖面的尺寸(亦即集光體2的寬幅或徑),是形成從光的入射側(一端)朝向射出側(另一端)變大的椀形狀。 The light concentrating body 2 is configured to illuminate light from the light source 1 at one end thereof, and to collect light from the other end while collecting the light. Further, the cross section of the light collector 2 orthogonal to the central axis CX (indicated by a dotted line) is circular, and the size of the cross section (that is, the width or diameter of the light collector 2) is formed from the incident side of the light ( One end) has a bowl shape that becomes larger toward the emission side (the other end).

在集光體2的入射側的端部,如圖1(a)~(c)所示,設 有包含中心軸CX且與中心軸CX平行的剖面成為四角形狀的圓柱狀的入射空間部3。該入射空間部3,是配置成圍著光源1的光放出側或覆蓋。又,形成入射空間部3的集光體2的內壁面,是形成使來自光源1的光進入用的光進入口,亦即形成光入射面4。光入射面4包含:位於圓柱狀的入射空間部3的圓周側面的側面入射面4a與對向於光源1的對向入射面4b,側面入射面4a是入射有來自光源1的射出角(與光軸所成的角)大的光,對向入射面4b是入射有射出角小的光。另一方面,集光體2的射出側的端部,是如圖1(a)及(c)所示,設有朝向入射側彎曲的(亦即將凹面朝向入射側)彎曲射出面5。 At the end of the incident side of the light collector 2, as shown in Figs. 1(a) to (c), A cylindrical incident space portion 3 having a central axis CX and a cross section parallel to the central axis CX has a quadrangular shape. The incident space portion 3 is disposed so as to surround or cover the light emitting side of the light source 1. Further, the inner wall surface of the light concentrating body 2 forming the incident space portion 3 is a light entrance opening for forming light from the light source 1, that is, the light incident surface 4 is formed. The light incident surface 4 includes a side incident surface 4a on the circumferential side surface of the cylindrical incident space portion 3 and an opposite incident surface 4b opposed to the light source 1, and the side incident surface 4a is incident on the exit angle from the light source 1 (and The light having a large angle formed by the optical axis is incident on the incident surface 4b with light having a small emission angle. On the other hand, the end portion on the emission side of the light-collecting body 2 is provided with a curved emission surface 5 which is curved toward the incident side (that is, the concave surface faces the incident side) as shown in FIGS. 1(a) and 1(c).

又,集光體2的外周側面的形狀,在包含中心軸CX且與中心軸CX平行的剖面形成略橢圓的一部分,而成為反射來自光源1的光的反射面6。亦即,反射面6是與中心軸CX平行的剖面形成大致橢圓形狀(的一部分)。因此,在反射面6被反射的光,是朝向反射面6的形狀的橢圓的焦點(橢圓的兩個焦點中離光源1遠的一側的焦點)集光。此外,作為集光性高的集光體,雖會有利用拋物線反射器等的放物面,可是會有橢圓對於光軸的半徑方向擴大小的傾向,抑制半徑方向的大小,適合集光體的小型化。 Moreover, the shape of the outer peripheral side surface of the light-collecting body 2 forms a slightly elliptical portion in a cross section including the central axis CX and parallel to the central axis CX, and becomes a reflecting surface 6 that reflects light from the light source 1. That is, the reflecting surface 6 has a substantially elliptical shape (part of the cross section) parallel to the central axis CX. Therefore, the light reflected on the reflecting surface 6 is collected by the focus of the ellipse (the focus on the side farther from the light source 1 among the two focal points of the ellipse) toward the shape of the reflecting surface 6. In addition, as a light collecting body having a high light collecting property, a projection surface such as a parabolic reflector may be used, but an ellipse tends to be small in the radial direction of the optical axis, and the size in the radial direction is suppressed, which is suitable for a light collecting body. Miniaturization.

利用集光體2的界面的全反射實現上述集光體2的側面的反射面6時,能具有對集光體2的外周側面反射比臨界角更淺的入射的光線。此時,藉由鏡面研磨外周側面,可提高反射效率。又,要求要有高的透過性之例如彎曲射 出面5也被鏡面研磨時,在集光體2的表面散射的光線減少,可高效率地透過光。因此,集光體2的表面,也包含外周側面、入射面、射出面對整體進行鏡面精加工為理想。可是,也可依必要,部分設置讓光散射的要素(微小凹凸、微小珠粒等),也可意圖性地打散光線方向來調整照度分布、配光分布。又,也可在集光體2的外周側面設置金屬蒸鍍、誘電體多層膜來形成反射面6。使用金屬蒸鍍、誘電體多層膜時,集光體2也可是中空。 When the reflecting surface 6 of the side surface of the above-mentioned light collecting body 2 is realized by total reflection at the interface of the light collecting body 2, it is possible to have light rays incident on the outer peripheral side surface of the light collecting body 2 shallower than the critical angle. At this time, the reflection efficiency can be improved by mirror-polishing the outer peripheral side surface. Also, it is required to have a high permeability such as a curved shot. When the exit surface 5 is also mirror-polished, light scattered on the surface of the light collector 2 is reduced, and light can be efficiently transmitted. Therefore, it is preferable that the surface of the light-collecting body 2 also includes the outer peripheral side surface, the incident surface, and the entire surface to be mirror-finished. However, elements that allow light to be scattered (fine irregularities, minute beads, etc.) may be partially provided as necessary, and the illuminance distribution and the light distribution may be adjusted by intentionally scattering the light direction. Further, a metal vapor deposition or an electric conductor multilayer film may be provided on the outer circumferential side surface of the light collector 2 to form the reflection surface 6. When the metal vapor deposition or the electric conductor multilayer film is used, the light collector 2 may be hollow.

在集光體2的射出側端部的周圍如圖示設有凸緣7。該凸緣7從照射側觀看照明裝置時形成環狀,以與構成集光體2的材質同樣的材質與集光體2一體成型。隔著複數個棒狀構件或由環狀的構件所構成的支撐構件11安裝該凸緣7與光源基板10或搭載光源基板10的板狀構件。亦即,集光體2是形成經由支撐構件11從光源基板10(或板狀構件)被支撐的構成。此時,在集光體2的底面與光源基板10(或板狀構件)之間隔開預定的間隔藉由支撐構件11支撐集光體2,而可使集光體2的底面不會接觸光源基板10(或板狀構件)的面。 A flange 7 is provided around the end portion of the light-collecting body 2 on the emission side. The flange 7 is formed in a ring shape when the illumination device is viewed from the irradiation side, and is formed integrally with the light collector 2 in the same material as the material constituting the light collector 2 . The flange 7 and the light source substrate 10 or the plate-like member on which the light source substrate 10 is mounted are attached via a plurality of rod-shaped members or a support member 11 composed of an annular member. That is, the light collector 2 is formed to be supported from the light source substrate 10 (or the plate member) via the support member 11. At this time, the light collector 2 is supported by the support member 11 at a predetermined interval between the bottom surface of the light collector 2 and the light source substrate 10 (or the plate member), so that the bottom surface of the light collector 2 does not contact the light source. The surface of the substrate 10 (or plate member).

支撐構件11是例如由樹脂或金屬所構成,支撐構件11與凸緣7及光源基板10(或板狀構件),也可例如由螺釘固定、接著劑所固定,又,也可在光源基板10(或板狀構件)設置複數個孔,將支撐構件11***這個而予以固定。又,也可在凸緣7的內側安裝支撐構件11,在凸緣7的外側也可安裝覆蓋未圖示的支架、可動托架等的裝置安裝器 具,或例如照明裝置的外周的樹脂或金屬製的圓筒狀的罩子(容器)。又,不使用支撐構件11,例如也可藉由接著劑等將集光體2的底面與光源基板10(或板狀構件)予以直接結合進行固定。 The support member 11 is made of, for example, a resin or a metal, and the support member 11 and the flange 7 and the light source substrate 10 (or a plate-like member) may be fixed by, for example, a screw and an adhesive, or may be on the light source substrate 10. (Or a plate member) A plurality of holes are provided, and the support member 11 is inserted into this to be fixed. Further, the support member 11 may be attached to the inner side of the flange 7, and a device mounter such as a bracket or a movable bracket (not shown) may be attached to the outer side of the flange 7. For example, a resin or a cylindrical cover (container) made of metal on the outer periphery of the illuminating device. Further, without using the support member 11, for example, the bottom surface of the light collector 2 and the light source substrate 10 (or the plate member) may be directly bonded and fixed by an adhesive or the like.

於此,在本實施例,如圖1(d)所示,彎曲射出面5的焦點是與反射面6的焦點F(反射面6的形狀的橢圓的兩個焦點中遠離光源1側的一方的焦點)構成大致一致。亦即,設定彎曲射出面5的形成位置、各面的曲率等而使兩者的面的焦點在位置F重疊。 Here, in the present embodiment, as shown in FIG. 1(d), the focus of the curved exit surface 5 is the one that is away from the light source 1 side among the two focal points of the ellipse of the shape of the reflecting surface 6 with the focal point F of the reflecting surface 6. The focus) constitutes roughly the same. In other words, the formation position of the curved exit surface 5, the curvature of each surface, and the like are set such that the focal points of the faces overlap at the position F.

也併用圖1(d)在以下針對這樣的構成的本實施例中的光學作用進行說明。於此,為了說明的簡單化,以光源1為1個的LED,使集光體2的中心軸CX與LED的光軸一致而被配置時為例進行說明。 The optical action in the present embodiment having such a configuration will be described below with reference to Fig. 1(d). Here, for simplification of the description, an example in which the light source 1 has one LED and the central axis CX of the light collector 2 is aligned with the optical axis of the LED will be described as an example.

從光源(LED)1射出的光線,在入射空間部3行進而射入到入射面4(側面入射面4a及對向入射面4b)。射入到入射面4的光線,在其邊界面折射,而射入到橢圓形狀的反射面6。如上述,因為反射面6被鏡面精加工(但是本發明並不是限定反射面6的表面粗度者),所以藉由將入射的光線予以全反射,在反射面6的形狀的橢圓的焦點F朝集光的方向反射。反射光就這樣朝向設在射出側端部的彎曲射出面5進行,藉由該彎曲射出面5,從反射面6折射朝向橢圓的焦點的光線。彎曲射出面5的凹面,因為具有朝向焦點F,使進行的光線平行化的作用,所以前述光線相對於透鏡的光軸成為大致平行光。其結果,從光源1射 出,通過集光體2射出的光線被聚集,而成為被平行化的光束。因此,來自照明裝置的光不會大幅被擴散而朝向與中心軸CX幾乎平行的方向,可對其前面的區域或範圍進行局部的照明。 The light emitted from the light source (LED) 1 travels in the incident space 3 and enters the incident surface 4 (the side incident surface 4a and the opposite incident surface 4b). The light incident on the incident surface 4 is refracted at its boundary surface and is incident on the elliptical reflecting surface 6. As described above, since the reflecting surface 6 is mirror-finished (but the invention does not limit the surface roughness of the reflecting surface 6), the focal point F of the ellipse in the shape of the reflecting surface 6 is totally reflected by the incident light. Reflecting in the direction of collecting light. The reflected light is thus directed toward the curved exit surface 5 provided at the end portion on the emission side, and the curved exit surface 5 refracts the light beam toward the focal point of the ellipse from the reflective surface 6. Since the concave surface of the curved exit surface 5 has a function of parallelizing the progress of the light toward the focal point F, the light ray is substantially parallel to the optical axis of the lens. As a result, shot from the light source 1 The light emitted through the light collector 2 is collected to become a parallelized light beam. Therefore, the light from the illumination device is not largely diffused and directed in a direction substantially parallel to the central axis CX, and the area or range in front of it can be partially illuminated.

上述構成中,光源1的位置並不是被配置在圖1的位置,而被配置在與焦點F不同的另一方的橢圓的焦點(亦即橢圓的兩個焦點中比較接近光源1側的焦點)時,從光源1的中心射出的光線可藉由反射面6反射到集光方向,並藉由彎曲射出面5予以平行化。 In the above configuration, the position of the light source 1 is not disposed at the position of FIG. 1 but is disposed at the focus of the other ellipse different from the focus F (that is, the focus of the ellipse is closer to the focus of the light source 1 side). At the time, the light emitted from the center of the light source 1 can be reflected by the reflecting surface 6 to the collecting direction, and parallelized by the curved emitting surface 5.

上述實施例中,在集光體2的光入射側,也可設置將光源1予以定位用的定位銷、突起。該等的構造,盡可能避開從光源1傳導到集光體2內的光路而設為理想,例如設在外周為理想。 In the above embodiment, the positioning pin and the projection for positioning the light source 1 may be provided on the light incident side of the light collector 2. These structures are preferably as far as possible from the light path conducted from the light source 1 into the light collector 2, and are preferably provided on the outer circumference, for example.

如此,在本實施例,藉由設在集光體2的外周側面的大致橢圓形狀的反射面6、與具有設在集光體2的光射出側端部的凹面的彎曲射出面5,將來自光源1的光予以集光而平行化。因此,根據本實施例,可提供即使小型集光性也高,且可將來自LED的光集中地對比較狹窄或被限定的範圍進行光的照射之聚光燈等的照明裝置、及用於這個的集光體。 As described above, in the present embodiment, the substantially elliptical reflecting surface 6 provided on the outer circumferential side surface of the light collecting body 2 and the curved emitting surface 5 having the concave surface provided on the light emitting side end portion of the light collecting body 2 will be Light from the light source 1 is collected and parallelized. Therefore, according to the present embodiment, it is possible to provide a illuminating device such as a spotlight that can illuminate a relatively narrow or limited range of light from a LED, even if the small concentrating property is high, and for this. Light collector.

[實施例2] [Embodiment 2]

接著,使用圖2說明本發明的第二實施例的一構成例。於此,圖2(a)表示第二實施例的照明裝置及集光體的 包含集光體的中心軸且與中心軸平行的剖視圖。圖2(b)表示從集光體的光入射側觀看的仰視圖,圖2(c)表示從集光體的光射出側觀看的仰視圖。 Next, a configuration example of the second embodiment of the present invention will be described using FIG. Here, FIG. 2(a) shows the illumination device and the light concentrator of the second embodiment. A cross-sectional view including a central axis of the light collector and parallel to the central axis. Fig. 2(b) is a bottom view as seen from the light incident side of the light concentrating body, and Fig. 2(c) is a bottom view as seen from the light emitting side of the light concentrating body.

本實施例與第一實施例不同的是第一實施例的入射空間部3的徑(亦即與中心軸CX正交的方向的寬幅尺寸)為一定的圓柱狀,而相對於此,在本實施例,如圖2所示,入射空間部32的徑是隨著從光源愈遠離(亦即朝向射出側端部)愈變小的特徵。亦即,本實施例的入射空間部32包含中心軸CX,且與中心軸CX平行的剖面為梯形狀,入射空間部32的側面入射面4a2從光源1側到射出側朝中心軸CX側傾斜。其他的點是與第一實施例同樣。只要具有這樣的傾斜者,則入射空間部32的側面入射面4a2,與中心軸CX平行的的剖面也可不是直線狀,而是傾斜角階段性的變更者、球面、其他的曲面形狀。 The present embodiment is different from the first embodiment in that the diameter of the incident space portion 3 of the first embodiment (that is, the wide dimension in the direction orthogonal to the central axis CX) is a certain cylindrical shape, and in contrast, In the present embodiment, as shown in Fig. 2, the diameter of the incident space portion 32 is characterized by becoming smaller as it goes away from the light source (i.e., toward the exit side end portion). That is, the incident space portion 32 of the present embodiment includes the central axis CX, and the cross section parallel to the central axis CX has a trapezoidal shape, and the side incident surface 4a2 of the incident space portion 32 is inclined from the light source 1 side to the emission side toward the central axis CX side. . Other points are the same as in the first embodiment. If there is such a slope, the side surface incident surface 4a2 of the incident space portion 32 may not be linear in cross section parallel to the central axis CX, but may be a change in the inclination angle step, a spherical surface, or another curved surface shape.

在本實施例,由於入射空間部32的側面入射面4a2朝向中心軸CX側傾斜而使隨著從光源1遠離入射空間部32的徑變小,所以以射出成型製造集光體2時,容易從模取出集光體2。亦即,本實施例的集光體2由射出成型製造時為理想。 In the present embodiment, since the side entrance surface 4a2 of the incident space portion 32 is inclined toward the central axis CX side, the diameter from the light source 1 away from the incident space portion 32 is reduced, so that it is easy to manufacture the light collector 2 by injection molding. The light collector 2 is taken out from the mold. That is, the light concentrating body 2 of the present embodiment is preferably produced by injection molding.

又,因為入射空間部32的側面入射面4a2傾斜,所以藉由下述的理由,可抑制藉由圓周入射面4a24產生的光源1的虛像的擴大,而可使集光性提昇。 Further, since the side entrance surface 4a2 of the incident space portion 32 is inclined, the expansion of the virtual image of the light source 1 by the circumferential incident surface 4a24 can be suppressed for the following reason, and the light collecting property can be improved.

從光源1所射出的光線雖藉由側面入射面被折射而作出光源1的虛像,可是其虛像一般變的比光源1更大。此 時,如果在側面入射面沒有折射,則虛像為光源1。亦即,折射愈小所形成的虛像愈變小。而且,對於光源1的橢圓形狀的反射面6的光源1的大小愈小,會有提昇聚集性的性質,再者由於橢圓形狀的反射面6對光源1的虛像作用,所以只要將光源1的虛像抑制的小,則可提高聚集性。因此,如本實施例,若使側面入射面4a2傾斜,則縮小從光源1射入到側面入射面4a2的光的入射角,可縮小在側面入射面4a2的折射的程度。其結果,抑制光源1的虛像的擴大,可提高來自光源1的光的聚集性。 Although the light emitted from the light source 1 is refracted by the side incident surface to make a virtual image of the light source 1, the virtual image generally becomes larger than the light source 1. this At the time, if there is no refraction on the side entrance surface, the virtual image is the light source 1. That is, the virtual image formed by the smaller the refraction becomes smaller. Further, as the size of the light source 1 of the elliptical reflecting surface 6 of the light source 1 is smaller, there is a property of enhancing the aggregation property, and since the reflecting surface 6 of the elliptical shape acts on the virtual image of the light source 1, only the light source 1 is used. The small reduction of virtual image can improve the aggregation. Therefore, according to the present embodiment, when the side entrance surface 4a2 is inclined, the incident angle of the light incident from the light source 1 to the side entrance surface 4a2 is reduced, and the degree of refraction of the side entrance surface 4a2 can be reduced. As a result, the expansion of the virtual image of the light source 1 is suppressed, and the aggregation of light from the light source 1 can be improved.

如此,本實施例除了上述第一實施例之外,更具有容易製造的效果、與抑制光源1的虛像擴大的效果。 As described above, in addition to the first embodiment described above, the present embodiment has an effect of being easy to manufacture and an effect of suppressing the expansion of the virtual image of the light source 1.

[實施例3] [Example 3]

接著,使用圖3說明本發明的第三實施例的一構成例。於此,圖3(a)表示第三實施例的照明裝置及集光體的包含集光體的中心軸,且與中心軸平行的剖視圖。圖3(b)表示從集光體的光入射側觀看的仰視圖,圖3(c)表示從集光體的光射出側觀看的仰視圖。 Next, a configuration example of the third embodiment of the present invention will be described using FIG. Here, Fig. 3(a) is a cross-sectional view showing the central axis of the illuminating device and the light concentrating body of the third embodiment, which is parallel to the central axis. Fig. 3(b) is a bottom view as seen from the light incident side of the light concentrating body, and Fig. 3(c) is a bottom view as seen from the light emitting side of the light concentrating body.

本實施例與第二實施例比較,在隨著入射空間部32的徑從光源遠離愈變小的點,亦即,在隨著入射空間部32的側面入射面4a2從光源1遠離愈往中心軸CX側傾斜的點相同。然而,在對向於該入射空間部32的光源1的面(圖1及圖2的對向入射面4b),設置將凸朝向光源1側的第1透鏡8,且在彎曲射出面5的中央將凸朝向光射出側 的第2透鏡9的點與第二實施例不同。其他的點是與第二實施例或第一實施例相同。 This embodiment is compared with the second embodiment in that the distance from the light source becomes smaller as the diameter of the incident space portion 32 becomes smaller, that is, from the side surface of the incident surface portion 32 from the light source 1 toward the center. The points on the side of the axis CX are the same. However, the surface of the light source 1 facing the incident space portion 32 (the opposite incident surface 4b of FIGS. 1 and 2) is provided with the first lens 8 that is convex toward the light source 1 side, and is bent at the exit surface 5 The center will be convex toward the light exit side The point of the second lens 9 is different from that of the second embodiment. Other points are the same as the second embodiment or the first embodiment.

本實施例的構成中,從光源1射出的光線中,射出角大且透過側面入射面4a的光線,是在側面入射面4a的邊界面被折射而射入橢圓形狀的反射面6,在該反射面6被全反射,藉由被設在射出面的凹面的彎曲射出面5被折射而聚集。另一方面,射出角小且沒有入射到側面入射面4a的光線被射入到第1透鏡8,而朝向第2透鏡9聚集。於此,將第1透鏡8設成將凸朝向光源1側的凸透鏡,將射入到第1透鏡8的光線予以集光,可使射入第2透鏡9的光束增加。又,將第2透鏡9設成將凸朝向光射出側的凸透鏡,藉此,使在第1透鏡8被聚集的光更聚集,而可更提高集光效果。此外,在本實施例,將第2透鏡9的口徑設的比第1透鏡8的口徑更大,使得在第1透鏡8被聚集的光的幾乎全部進入到第2透鏡9。 In the configuration of the present embodiment, among the light beams emitted from the light source 1, the light having a large emission angle and transmitted through the side entrance surface 4a is refracted at the boundary surface of the side entrance surface 4a, and is incident on the elliptical reflecting surface 6. The reflecting surface 6 is totally reflected, and is condensed by the curved emitting surface 5 provided on the concave surface of the emitting surface to be gathered. On the other hand, light having a small emission angle and not incident on the side entrance surface 4a is incident on the first lens 8, and is concentrated toward the second lens 9. Here, the first lens 8 is provided as a convex lens that is convex toward the light source 1 side, and the light that has entered the first lens 8 is collected, and the light beam incident on the second lens 9 can be increased. Further, the second lens 9 is provided with a convex lens that is convex toward the light emitting side, whereby the light collected by the first lens 8 is more concentrated, and the light collecting effect can be further enhanced. Further, in the present embodiment, the diameter of the second lens 9 is set larger than the diameter of the first lens 8, so that almost all of the light collected by the first lens 8 enters the second lens 9.

於此,第1透鏡8、與第2透鏡9所為的聚集性,是藉由兩透鏡的合成焦點距離所決定,只要將光源1配置在藉由合成焦點距離所決定的合成焦點位置,則可藉由第1透鏡8與第2透鏡9良好地將來自光源1的光予以集光。因此,在本實施例,作成將光源1配置在第1透鏡8與第2透鏡9的合成焦點位置者。據此,即使光源1的發光面積大,也可使來自第2透鏡9的散發角度減少並使聚集性提高。 Here, the aggregation property of the first lens 8 and the second lens 9 is determined by the combined focal length of the two lenses, and the light source 1 can be placed at the composite focus position determined by the combined focal length. The light from the light source 1 is well collected by the first lens 8 and the second lens 9. Therefore, in the present embodiment, the light source 1 is disposed at the combined focus position of the first lens 8 and the second lens 9. According to this, even if the light-emitting area of the light source 1 is large, the emission angle from the second lens 9 can be reduced and the aggregation property can be improved.

將光源1配置在合成焦點位置時,合成焦點距離大的 時候,因為光源1與第1透鏡8的距離變大,所以從照明裝置的小型化的觀點並不理想。照明裝置的小型化的理由上,不能確保光源1與第1透鏡8的距離時,也可將第1透鏡8換成凸透鏡,作成將凹朝向光源1側的凹透鏡。由於藉由將第1透鏡8作成曲率大的凹透鏡,可使第1透鏡8與第2透鏡9的合成透鏡的焦點位置接近第一透鏡8側,所以可使光源1一面接近第1透鏡8,一面與上述合成透鏡的焦點位置對齊。因此,根據這樣的構成,一面使照明裝置小型化,可依面提高第1透鏡8與第2透鏡9的合成透鏡所為的聚集性。 When the light source 1 is disposed at the composite focus position, the combined focus distance is large At this time, since the distance between the light source 1 and the first lens 8 is increased, it is not preferable from the viewpoint of downsizing of the illumination device. When the distance between the light source 1 and the first lens 8 cannot be ensured, the first lens 8 can be replaced with a convex lens to form a concave lens that is concave toward the light source 1 side. Since the first lens 8 is formed as a concave lens having a large curvature, the focal position of the combined lens of the first lens 8 and the second lens 9 can be made closer to the first lens 8 side, so that the light source 1 can be brought closer to the first lens 8 One side is aligned with the focus position of the above synthetic lens. Therefore, according to such a configuration, the illuminating device can be downsized, and the aggregation property of the synthetic lens of the first lens 8 and the second lens 9 can be improved.

此外,上述第1透鏡8是如第一實施例,即使是圓柱狀的入射空間部者也可同樣地設置。 Further, the first lens 8 is the same as the first embodiment, and can be similarly provided even in the case of a cylindrical incident space portion.

又,如圖4(a)所示,使第2透鏡9的焦點大致位在第1透鏡8,第1透鏡8也可將光源1的實像成像在第2透鏡9。依據上述的構成,可有效率地將來自光源1的射出光射入第2透鏡9。 Further, as shown in FIG. 4(a), the focus of the second lens 9 is substantially positioned on the first lens 8, and the first lens 8 can image the real image of the light source 1 on the second lens 9. According to the above configuration, the light emitted from the light source 1 can be efficiently incident on the second lens 9.

於此,若將藉由第1透鏡8被投影(或成像)到第2透鏡9的光源1的大小設的比第2透鏡9的口徑更小,則可使來自光源1的射出光由效率地通過第2透鏡9。因此,對第2透鏡9的口徑設定第1透鏡8的倍率(曲率)、與第2透鏡9的距離、或與光源1的距離,而使被投影到第2透鏡9的光源1的實像變小為理想。 Here, if the size of the light source 1 projected (or imaged) by the first lens 8 to the second lens 9 is smaller than the diameter of the second lens 9, the light emitted from the light source 1 can be made efficient. The ground passes through the second lens 9. Therefore, the magnification (curvature) of the first lens 8, the distance from the second lens 9, or the distance from the light source 1 is set to the aperture of the second lens 9, and the real image of the light source 1 projected onto the second lens 9 is changed. Small is ideal.

再者,第2透鏡9成為投影來自位於其焦點位置的第1透鏡8的光學像之光學系。也可藉由從第2透鏡9射出 的光束的所期望的散發角決定該第2透鏡9的焦點距離。例如,若成像在第1透鏡8的光源1的實像的大小愈大,則從第2透鏡9射出的光束的散發角度變大,相反若光源1的實像愈小,則散發角度變小。由該等的關係決定從第2透鏡9射出的光束的所期望的散發角度而可設定焦點距離。關於前述散發角度,是與作為目標的照明裝置的散發角度接近為理想。 Further, the second lens 9 is an optical system that projects an optical image from the first lens 8 located at the focus position thereof. Can also be emitted from the second lens 9 The desired emission angle of the light beam determines the focal length of the second lens 9. For example, when the size of the real image of the light source 1 imaged on the first lens 8 is larger, the emission angle of the light beam emitted from the second lens 9 is increased, and conversely, the smaller the real image of the light source 1 is, the smaller the emission angle is. The focal length can be set by determining the desired emission angle of the light beam emitted from the second lens 9 by these relationships. It is preferable that the aforementioned emission angle is close to the emission angle of the target illumination device.

因為從光源1射出的光線在到達第1透鏡8為止的距離被散發或擴散,所以第1透鏡5上的照度分布與光源1的發光面上的照度分布比較被均一化。因此,可使從集光體2被射出的光線中,通過第1透鏡8與第2透鏡9的光束被空間均勻化而成為被均質化的照射光。 Since the distance from the light emitted from the light source 1 to the first lens 8 is dissipated or diffused, the illuminance distribution on the first lens 5 is made uniform compared with the illuminance distribution on the light-emitting surface of the light source 1. Therefore, among the light beams emitted from the light collector 2, the light beams that have passed through the first lens 8 and the second lens 9 are spatially uniformized to become uniformized irradiation light.

因此,根據上述構成,例如即使在光源1的發光面上有顏色不均發生時、有亮度不均時,也可獲得在空間上均質的照射光。 Therefore, according to the above configuration, for example, even when color unevenness occurs on the light-emitting surface of the light source 1, when there is unevenness in luminance, spatially uniform illumination light can be obtained.

The arrangement of the light source 1 and each of the light collectors 2 is not limited to the above. The flange 7 can also be integrally formed with the integrated light collector 21 as described in the first embodiment, and can also be made into different parts.

根據這樣的本實施例的構成,因為具有複數光源1,所以可提供輸出大的照明裝置。再者,因為可將複數個光學零件(集光體2)整合成1個而予以一體成形,所以對於消減組裝的工時有效果,可提高生產性。 According to the configuration of the present embodiment as described above, since the plurality of light sources 1 are provided, it is possible to provide an illumination device having a large output. In addition, since a plurality of optical components (light collectors 2) can be integrally formed by integrating them into one, it is effective in reducing the number of man-hours for assembly, and productivity can be improved.
