Description

本発明は、テールランプ、ストップランプ、ターンシグナルランプ、バックランプ等の車両用信号灯具に関するものである。   The present invention relates to a vehicle signal lamp such as a tail lamp, a stop lamp, a turn signal lamp, and a back lamp.

テールランプ等の車両用信号灯具には、省電力で耐久性の高いＬＥＤ（発光ダイオード）を光源とするものがあり、斯かる車両用信号灯具においては、ＬＥＤに対向する入射面から入射するＬＥＤからの光を導光体によって導光することが行われている（例えば、特許文献１参照）。   Some vehicle signal lamps such as tail lamps use an LED (light-emitting diode) that is power-saving and highly durable as a light source. In such a vehicle signal lamp, an LED incident from an incident surface facing the LED is used. The light is guided by a light guide (see, for example, Patent Document 1).

特開２０１１−１９８５３６号公報JP 2011-198536 A

しかしながら、導光体を用いた従来の車両用信号灯具においては、ＬＥＤ等の光源から導光体に入射する光を導光しつつ、導光体に形成された拡散ステップ等によって光を反射拡散させて灯具照射方向に出射させることによって導光体自体を光らせる構成が採用されていたため、発光が不均一な線状となり、均一な面発光を実現することができないという問題があった。   However, in a conventional vehicle signal lamp using a light guide, light is reflected and diffused by a diffusion step or the like formed in the light guide while guiding light incident on the light guide from a light source such as an LED. Since the light guide itself is illuminated by being emitted in the lamp irradiation direction, there is a problem that the light emission becomes non-uniform linear and uniform surface light emission cannot be realized.

本発明は上記問題に鑑みてなされたもので、その目的とする処は、均一な面発光を実現することができる車両用信号灯具を提供することにある。   The present invention has been made in view of the above problems, and an object thereof is to provide a vehicular signal lamp capable of realizing uniform surface light emission.

上記目的を達成するため、請求項１記載の発明は、光源と、該光源に対向する入射面から入射する前記光源からの光を導光する導光体を備えた車両用信号灯具において、
前記導光体から灯具照射方向に出射する光を遮る遮光体を導光体の長手方向に沿って配置し、
前記導光体から出射される光のうち前記遮光体によって遮られない光を灯具照射方向に向けて反射させるリフレクタと、前記遮光体に沿って該遮光体の両側に配置された透光性部材とを設け、
前記導光体に、入射面から内部に入射して当該導光体の長手方向に向かう光を拡散して出射させる拡散出射面を形成し、
前記リフレクタの前記導光体を中心としてその両側に拡散反射面と非拡散反射面をそれぞれ設け、
前記導光体から出射する光を、前記遮光体の両側に２つの発光面を形成して灯具照射方向に向かって照射させることを特徴とする。
In order to achieve the above object, the invention according to claim 1 is a vehicle signal lamp comprising a light source and a light guide that guides light from the light source incident from an incident surface facing the light source.
A light shield that blocks light emitted from the light guide in the lamp irradiation direction is disposed along the longitudinal direction of the light guide,
A reflector that reflects light that is not blocked by the light blocking body out of the light emitted from the light guide body toward a lamp irradiation direction, and a translucent member that is disposed on both sides of the light blocking body along the light blocking body And
A diffusion exit surface for diffusing and emitting light entering the inside of the light guide from the entrance surface and traveling in the longitudinal direction of the light guide is formed on the light guide,
A diffuse reflection surface and a non-diffuse reflection surface are respectively provided on both sides of the light guide of the reflector.
The light emitted from the light guide is formed in two light emitting surfaces on both sides of the light blocking body and is irradiated in the lamp irradiation direction.

請求項２記載の発明は、請求項１記載の発明において、前記２つの発光面は、前記リフレクタの拡散反射面側の発光面と、前記非拡散反射面側の発光面とされ、前記非拡散反射面側の発光面の均一感を前記拡散反射面側の発光面の均一感よりも低くしたことを特徴とする。
The invention according to claim 2 is the invention according to claim 1, wherein the two light emitting surfaces are a light emitting surface on the diffuse reflection surface side of the reflector and a light emitting surface on the non-diffuse reflective surface side, and the non-diffuse surface. The uniformity of the light emitting surface on the reflecting surface side is made lower than the uniformity of the light emitting surface on the diffuse reflecting surface side .

本発明によれば、光源から出射して導光体に入射した光は、遮光体のために導光体から灯具照射方向に向かって直接出射せず、リフレクタによって一旦反射して拡散し、その反射光が灯具照射方向に向かうため、リフレクタの全体が光って均一な面発光が実現する。又、リフレクタによって反射した光が遮光体の両側に配置された透光性部材を通過して灯具照射方向に照射されるため、遮光体の左右に計２つの発光面を形成することができる。
According to the present invention, the light emitted from the light source and incident on the light guide is not directly emitted from the light guide toward the lamp irradiation direction because of the light shielding body, but is once reflected and diffused by the reflector. Since the reflected light is directed in the lamp illumination direction, the entire reflector shines to achieve uniform surface emission. Moreover, since the light reflected by the reflector passes through the translucent members disposed on both sides of the light shielding body and is irradiated in the lamp illumination direction, a total of two light emitting surfaces can be formed on the left and right sides of the light shielding body.

そして、本発明によれば、リフレクタの一方の反射面が拡散反射面とされ、他方の反射面が非拡散反射面とされているため、拡散反射面で反射して出射する照明光は、非拡散反射面リフレクタの一方の反射面が拡散反射面とされ、他方の反射面が非拡散反射面とされているため、拡散反射面で反射して出射する照明光は、非拡散反射面にて反射して出射する照明光に比べて、発光面の均一感を一層高めることができる反面、他方の非拡散反射面においては、拡散反射面に比べて発光面の均一感の低い発光面を実現することができるため、異なる面発光感の面発光を同時に得ることができる。
According to the present invention, one of the reflecting surfaces of the reflector is a diffuse reflecting surface, and the other reflecting surface is a non-diffusing reflecting surface. one of the reflective surface of the diffuse reflection surface reflector is a diffuse reflector, since the other reflecting surface is a non-diffuse reflection surface, the illumination light emitted is reflected by the diffuse reflection surface, hands non reflecting diffuser Compared with illumination light that is reflected and emitted, the uniformity of the light emitting surface can be further enhanced. On the other hand, the other non-diffusive reflecting surface realizes a light emitting surface with a lower uniformity of the light emitting surface than the diffuse reflecting surface Therefore, surface emission with different surface emission feeling can be obtained simultaneously.

＜参考例＞
図１は本発明の参考例に係る車両用信号灯具を備えるリヤコンビネーションランプの正面図、図２は図１のＡ−Ａ線断面図であり、図示のリヤコンビネーションランプ１は、車両の後部左右に設けられるものであって、図１に示すように、ハウジング２とその車両後方（図１の手前側）に開口する開口部を覆う透明なアウタレンズ３によって画成された灯室４内に車両用信号灯具であるターンシグナルランプ５とストップランプ６及びテールランプ７を収容して構成されている。尚、左右のリヤコンビネーションランプ１は、左右対称であって、その基本構成は同じであるため、以下、一方（左側）のリヤコンビネーションランプ１についてのみ図示及び説明する。
< Reference example >
FIG. 1 is a front view of a rear combination lamp having a vehicle signal lamp according to a reference example of the present invention, FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1, and the rear combination lamp 1 shown in FIG. As shown in FIG. 1, the vehicle is placed in a lamp chamber 4 defined by a transparent outer lens 3 covering a housing 2 and an opening opening behind the vehicle (front side in FIG. 1). A turn signal lamp 5, a stop lamp 6, and a tail lamp 7, which are signal lamps for use, are accommodated. Since the left and right rear combination lamps 1 are symmetrical and have the same basic configuration, only one (left side) rear combination lamp 1 will be illustrated and described below.

前記ターンシグナルランプ５は、車両の内側（図１の右側）に配されており、その上方に前記ストップランプ６が配されている。そして、これらのターンシグナルランプ５とストップランプ６の横（車両外側）には、正面視（車両後面視）でＬ字状に屈曲した前記テールランプ７がターンシグナルランプ５とストップランプ６を横方向から取り囲むように配置されている。   The turn signal lamp 5 is disposed on the inner side (right side in FIG. 1) of the vehicle, and the stop lamp 6 is disposed above the turn signal lamp 5. Next to the turn signal lamp 5 and the stop lamp 6 (outside of the vehicle), the tail lamp 7 bent in an L shape when viewed from the front (viewed from the rear of the vehicle) extends the turn signal lamp 5 and the stop lamp 6 laterally. It is arranged to surround from.

ここで、上記テールランプ７は、その幅方向中心部に沿ってＬ字状に屈曲する長い棒状の導光体８を備えており、図１に示すように、この導光体８の長手方向両端面の入射面８ａに対向する位置には光源であるＬＥＤ９がそれぞれ配置されている。そして、図２に示すように、導光体８の車両後方（図２の下方）には、ＬＥＤ９から灯具照射方向（図２の下方）に向かって出射する光を遮る横断面コの字状（チャンネル状）の遮光体１０が導光体８を車両後方から覆うように該導光体８に沿って正面視Ｌ字状に配置されている。   Here, the tail lamp 7 includes a long rod-shaped light guide 8 bent in an L shape along the center in the width direction, and as shown in FIG. LEDs 9 as light sources are respectively arranged at positions facing the incident surface 8a of the surface. Then, as shown in FIG. 2, at the rear of the light guide 8 (downward in FIG. 2), a U-shaped cross section that blocks light emitted from the LED 9 toward the lamp irradiation direction (downward in FIG. 2) A (channel-shaped) light-shielding body 10 is arranged in an L shape in front view along the light guide 8 so as to cover the light guide 8 from the rear of the vehicle.

ところで、上記導光体８は、これを車両前方から覆うように配置された正面視Ｌ字状のリフレクタ１１の幅方向中心部に配置されている。ここで、リフレクタ１１は、導光体８から出射される光のうちの前記遮光体１０によって遮られない光（車両前方に向かう光）を灯具照射方向（図２の下方）に向けて反射させるものであって、これの内面には回転楕円状の反射面１１ａが形成されている。尚、リフレクタ１１の反射面１１ａには、その反射率を高めるためにアルミ蒸着等の反射処理が施されている。   By the way, the light guide 8 is disposed at the center in the width direction of the L-shaped reflector 11 that is disposed so as to cover the light guide 8 from the front of the vehicle. Here, the reflector 11 reflects light (light traveling toward the front of the vehicle) out of the light emitted from the light guide 8 that is not blocked by the light shield 10 toward the lamp irradiation direction (downward in FIG. 2). A spheroid reflecting surface 11a is formed on the inner surface. The reflecting surface 11a of the reflector 11 is subjected to a reflection process such as aluminum vapor deposition in order to increase its reflectance.

又、図２に示すように、リフレクタ１１の車両後方（図２の下方）に向かって開口する開口部の遮光体１０の左右両側部分には、遮光体１０に沿う正面視Ｌ字状の透明なインナレンズ１２がそれぞれ配置されている。
Further, as shown in Figure 2, the left and right side portions of the light shielding unit 10 of the opening that opens toward the vehicle rear side of the reflector 11 (downward in FIG. 2), transparent front view L-shape along the light shielding unit 10 Each inner lens 12 is arranged.

以上のように構成されたリヤコンビネーションランプ１においては、夜間に運転者がスイッチ操作することによってテールランプ７が点灯する。即ち、運転者によるスイッチ操作によって不図示のバッテリ電源から光源である２つのＬＥＤ９にそれぞれ電流が供給されると、各ＬＥＤ９が起動されて発光する。すると、各ＬＥＤ９から出射する光は、導光体８の長手方向両端面の入射面８ａから導光体８内に入射し、該導光体８の内部を進む過程で導光体８の周面で反射して導光体８から出射するが、車両後方（図２の下方）に向かう光は遮光体１０によって遮られて車両後方には直接出射しない。
In the rear combination lamp 1 configured as described above, the tail lamp 7 is turned on when the driver performs a switch operation at night. That is, when a current is supplied from a battery power source (not shown) to the two LEDs 9 that are light sources by a switch operation by the driver, each LED 9 is activated to emit light. Then, the light emitted from each LED 9 enters the light guide 8 from the incident surfaces 8a on both end faces in the longitudinal direction of the light guide 8, and in the process of traveling inside the light guide 8, the periphery of the light guide 8 Although the light is reflected from the surface and emitted from the light guide 8, the light traveling toward the rear of the vehicle (downward in FIG. 2) is blocked by the light shielding body 10 and is not directly emitted to the rear of the vehicle.

他方、導光体８から車両前方に向かう光Ｌは、図２に示すようにリフレクタ１１の反射面１１ａで反射して拡散し、平行光となって車両後方に向かい、遮光体１０の左右に配置されたインナレンズ１２を透過して配光が制御され、最終的にはアウタレンズ３を通過して車両後方へと出射する。   On the other hand, the light L traveling from the light guide 8 toward the front of the vehicle is reflected and diffused by the reflecting surface 11a of the reflector 11 as shown in FIG. Light distribution is controlled by passing through the arranged inner lens 12 and finally passes through the outer lens 3 and exits to the rear of the vehicle.

以上のように、本参考例に係るテールランプ７においては、各ＬＥＤ９から出射して導光体８に入射した光は、遮光体１０のために導光体８から灯具照射方向に向かって直接出射せず、リフレクタ１１によって一旦反射して拡散し、その反射光が灯具照射方向に向かうため、リフレクタ１１の全体が光って均一な面発光が実現する。
As described above, in the tail lamp 7 according to this reference example , the light emitted from each LED 9 and incident on the light guide 8 is directly emitted from the light guide 8 toward the lamp irradiation direction for the light blocking body 10. Without being reflected, the light is once reflected and diffused by the reflector 11, and the reflected light travels in the lamp illumination direction, so that the entire reflector 11 is illuminated and uniform surface light emission is realized.

又、本参考例では、リフレクタ１１によって反射した光Ｌが遮光体１０の左右両側に配置されたインナレンズ１２を通過して車両後方に照射されるため、遮光体１０の左右に計２つの発光面を形成することができるという効果も得られる。
Further, in this reference example , the light L reflected by the reflector 11 passes through the inner lenses 12 arranged on the left and right sides of the light shielding body 10 and is irradiated to the rear of the vehicle. The effect that a surface can be formed is also obtained.

＜実施の形態＞
次に、本発明の実施の形態を図３に基づいて以下に説明する。尚、図３は発明の実施の形態に係る車両用信号灯具の断面図である。
<Form state of implementation>
Next, the shape condition of the present invention will be described below with reference to FIG. Incidentally, FIG. 3 is a sectional view of a vehicle signal lamp according to the shape condition of the embodiment of the invention.

前記参考例では、棒状の導光体８の長手方向の中心軸を中心として左側及び右側の反射面１１ａでそれぞれ反射した光が灯具照射方向に向かうようにしていたが、本実施の形態では、図３に示すように導光体８は、コア部分８ａとスキン層８ｂの２層構造として構成されている。
In the reference example , the light reflected by the left and right reflecting surfaces 11a about the central axis in the longitudinal direction of the rod-shaped light guide 8 is directed toward the lamp irradiation direction, but in this embodiment, As shown in FIG. 3, the light guide 8 is configured as a two-layer structure of a core portion 8a and a skin layer 8b.

上記コア部分８ａは、透明樹脂材料から成る長い棒状の導光体として構成されており、前記スキン層８ｂは、コア部分８ａの周囲、少なくともリフレクタ１１の拡散反射面１１ａに対向する側の面の表面に多層構造として構成されている。ここで、スキン層８ｂは、内部に光拡散材を添加した拡散層若しくは表面を荒らした拡散面としての拡散出射面である。
The core portion 8a is configured as a long rod-shaped light guide made of a transparent resin material, and the skin layer 8b is formed around the core portion 8a, at least on the surface facing the diffuse reflection surface 11a of the reflector 11. A multi-layer structure is formed on the surface. Here, the skin layer 8b is a diffusion outgoing surface as a diffusion layer having a light diffusing material added therein or a diffusion surface roughened on the surface.

又、リフレクタ１１は、導光体８を中心として図３の左側の反射面１１ｄと右側の反射面１１ｂを備えており、左側の反射面１１ｄは平滑な反射面とされ、その表面反射率を高めるためにアルミ蒸着等の反射膜１１ｅが形成されている。そして、右側の反射面１１ｂは、梨地状加工、シボ加工等の表面を荒らす処理が施された拡散反射面とされ、その表面反射率を高めるためにアルミ蒸着等の拡散反射膜１１ｅが形成されている。尚、他の構成は前記参考例と同様であるため、これについての説明は省略する。
Further, the reflector 11 includes a left reflecting surface 11d and a right reflecting surface 11b in FIG. 3 with the light guide 8 as a center, and the left reflecting surface 11d is a smooth reflecting surface. In order to increase the thickness, a reflective film 11e such as aluminum vapor deposition is formed. The right reflecting surface 11b is a diffuse reflecting surface that has been subjected to a surface roughening process such as a satin finish or a textured process, and a diffuse reflecting film 11e such as aluminum vapor deposition is formed to increase the surface reflectance. ing. Since other configurations are the same as those of the reference example , description thereof will be omitted.

而して、本実施の形態に係るテールランプ７においても、各ＬＥＤ９から出射して導光体８に入射した光は、遮光体１０のために導光体８から灯具照射方向に向かって直接出射しない。又、導光体８のコア部分８ａを通った光は、スキン層８ｂにて拡散して出射し、スキン層８ｂを通過してリフレクタ１１で一旦反射し、その反射光が灯具照射方向に向かう。このとき、リフレクタ１１の一方の反射面１１ｂが拡散反射面とされ、他方の反射面１１ｄが非拡散反射面とされているため、拡散反射面１１ｂで反射して出射する照明光は、非拡散反射面１１ｄにて反射して出射する照明光に比べて、発光面の均一感を一層高めることができる。他方の非拡散反射面１１ｄにおいては、拡散反射面１１ｂに比べて発光面の均一感の低い発光面を実現することができるため、本実施の形態に係るテールランプ７においては、異なる面発光感の面発光を同時に得ることができる。   Thus, also in the tail lamp 7 according to the present embodiment, the light emitted from each LED 9 and incident on the light guide 8 is directly emitted from the light guide 8 toward the lamp irradiation direction for the light shield 10. do not do. The light that has passed through the core portion 8a of the light guide 8 is diffused and emitted by the skin layer 8b, passes through the skin layer 8b, is reflected by the reflector 11, and the reflected light travels in the lamp illumination direction. . At this time, since one reflection surface 11b of the reflector 11 is a diffuse reflection surface and the other reflection surface 11d is a non-diffuse reflection surface, the illumination light reflected and emitted from the diffuse reflection surface 11b is non-diffuse. Compared with the illumination light reflected and emitted from the reflecting surface 11d, the uniformity of the light emitting surface can be further enhanced. The other non-diffusive reflecting surface 11d can realize a light emitting surface having a light emitting surface with a lower uniformity than that of the diffuse reflecting surface 11b. Therefore, in the tail lamp 7 according to the present embodiment, a different surface emitting feeling. Surface emission can be obtained simultaneously.

尚、以上は本発明をテールランプに対して適用した形態について説明したが、本発明は、テールランプ以外のターンシグナルランプやバックランプ等の他の任意の車両用信号灯具に対しても同様に適用可能であることは勿論である。   In the above description, the present invention is applied to the tail lamp. However, the present invention can be similarly applied to any other vehicle signal lamp such as a turn signal lamp and a back lamp other than the tail lamp. Of course.
