Description

本発明は新規な車輌用灯具に関する。詳しくは、点灯により表示する機能が異なる２種類の光源を備えた車輌用灯具において、２種類の光源による発光視認領域の被視認性を高める技術に関する。   The present invention relates to a novel vehicular lamp. More specifically, the present invention relates to a technique for improving visibility of a light emission visual recognition area using two types of light sources in a vehicle lamp including two types of light sources that display different functions when turned on.

点灯により表示する機能が異なる２種類の光源を備えた車輌用灯具に、例えば、特許文献１に示されたものがある。   For example, Patent Document 1 discloses a vehicular lamp that includes two types of light sources that display different functions when turned on.

特許文献１に示された車輌用灯具にあっては、第１の光源の光が導光板の後面で反射して前方へ照射され、第２の光源の光が前記導光板を透過して前方へ照射される。従って、第１の光源と第２の光源とを各別に点灯することによって、それぞれ異なる機能を表示することが出来る。   In the vehicular lamp disclosed in Patent Document 1, the light from the first light source is reflected by the rear surface of the light guide plate and irradiated forward, and the light from the second light source passes through the light guide plate and forwards. Is irradiated. Therefore, different functions can be displayed by lighting the first light source and the second light source separately.

特開２００３−１４１９０９号公報JP 2003-141909 A

ところで、上記した特許文献１に示された車輌用灯具にあっては、第２の光源の光の一部が導光板内で乱反射して広い面積で発光してしまうため、第１の光源と第２の光源とを同時に点灯すると、２つの光源光が入り交じって発光してしまうため、如何なる機能の表示が為されているか判然としないと言う問題がある。   By the way, in the vehicular lamp shown in Patent Document 1 described above, a part of the light from the second light source is diffusely reflected in the light guide plate and emits light over a wide area. If the second light source is turned on at the same time, the two light sources are mixed and emit light, which causes a problem that it is not clear what function is being displayed.

本発明は、上記した問題に鑑みて、２種類の光源による発光視認領域の被視認性を高めることを課題とする。   In view of the above-described problems, an object of the present invention is to improve the visibility of a light emission visual recognition area using two types of light sources.

本発明車輌用灯具は、上記した課題を解決するために、灯具光軸に対してほぼ垂直な方向に光を出射する第１の発光ダイオード（以下、「ＬＥＤ」という）と、前記第１のＬＥＤの光をほぼ前方へと反射するリフレクタと、ほぼ灯具光軸方向に光を出射する第２のＬＥＤと、灯具光軸方向に延び、前記第２のＬＥＤの光を後端から前端へと導光する透明材料から成る導光体とを備え、前記導光体のほぼ前後方向に延びる幅広の主平面は前記第１のＬＥＤの出射方向に対してほぼ垂直な角度を成し、前記第１のＬＥＤの光の一部は前記導光体の主平面を透過して前記リフレクタに到達する。   In order to solve the above-described problem, the vehicle lamp of the present invention includes a first light emitting diode (hereinafter referred to as “LED”) that emits light in a direction substantially perpendicular to the optical axis of the lamp, and the first light emitting diode. A reflector that reflects the light of the LED substantially forward, a second LED that emits light substantially in the direction of the optical axis of the lamp, and a light that extends in the direction of the optical axis of the lamp, and transmits the light of the second LED from the rear end to the front end A wide main plane extending substantially in the front-rear direction of the light guide body at an angle substantially perpendicular to the emission direction of the first LED, and a light guide body made of a transparent material for guiding light. Part of the light of one LED passes through the main plane of the light guide and reaches the reflector.

従って、本発明車輌用灯具にあっては、第１のＬＥＤの光はリフレクタで反射されて前方へと照射され、第２のＬＥＤの光は導光体の前端から前方へ出射される。そのため、第１のＬＥＤと第２のＬＥＤによって光る領域が判然と区別される。   Therefore, in the vehicular lamp of the present invention, the light of the first LED is reflected by the reflector and irradiated forward, and the light of the second LED is emitted forward from the front end of the light guide. Therefore, the area illuminated by the first LED and the second LED is clearly distinguished.

本発明車輌用灯具は、灯具光軸に対してほぼ垂直な方向に光を出射する第１のＬＥＤと、前記第１のＬＥＤの光をほぼ前方へと反射するリフレクタと、ほぼ灯具光軸方向に光を出射する第２のＬＥＤと、灯具光軸方向に延び、前記第２のＬＥＤの光を後端から前端へと導光する透明材料から成る導光体とを備え、前記導光体のほぼ前後方向に延びる幅広の主平面は前記第１のＬＥＤの出射方向に対してほぼ垂直な角度を成し、前記第１のＬＥＤの光の一部は前記導光体の主平面を透過して前記リフレクタに到達することを特徴とする。   The vehicular lamp according to the present invention includes a first LED that emits light in a direction substantially perpendicular to a lamp optical axis, a reflector that reflects light from the first LED substantially forward, and a lamp optical axis direction. And a light guide made of a transparent material extending in the optical axis direction of the lamp and guiding the light of the second LED from the rear end to the front end. The wide main plane extending substantially in the front-rear direction forms an angle substantially perpendicular to the emission direction of the first LED, and a part of the light of the first LED is transmitted through the main plane of the light guide. And reaching the reflector.

従って、本発明車輌用灯具にあっては、第１のＬＥＤの光はリフレクタで反射されて前方へと照射され、第２のＬＥＤの光は導光体の前端から前方へ出射される。そのため、第１のＬＥＤによってリフレクタの前面が明るく視認され、第２のＬＥＤによっては導光体の前端が明るく視認される。そのため、第１のＬＥＤと第２のＬＥＤによって光る領域が判然と区別され、第１のＬＥＤと第２のＬＥＤを同時に点灯した場合でも、それぞれのＬＥＤの点灯色が各別であれば、第１のＬＥＤと第２のＬＥＤが同時に点灯していると視認される。   Therefore, in the vehicular lamp of the present invention, the light of the first LED is reflected by the reflector and irradiated forward, and the light of the second LED is emitted forward from the front end of the light guide. Therefore, the front surface of the reflector is visually recognized brightly by the first LED, and the front end of the light guide is visually recognized brightly by the second LED. Therefore, the area illuminated by the first LED and the second LED is clearly distinguished, and even if the first LED and the second LED are turned on at the same time, if the lighting color of each LED is different, It is visually recognized that one LED and the second LED are lit simultaneously.

請求項２に記載した発明にあっては、前記第２のＬＥＤ及び該第２のＬＥＤの光が入射する前記導光体の入射部は前記リフレクタの背面側に位置したので、第２のＬＥＤから出射されたが、導光体には入射しなかった光は、リフレクタによって前方へ照射されることが阻止される。従って、第２のＬＥＤの光のうち導光体に入射しなかった光が、制御されない光として前方へ出射されることを防止することが出来る。   In the invention described in claim 2, the second LED and the incident portion of the light guide on which the light of the second LED is incident are located on the back side of the reflector. The light that is emitted from the light but does not enter the light guide is prevented from being irradiated forward by the reflector. Therefore, it is possible to prevent the light that has not entered the light guide from the light emitted from the second LED from being emitted forward as uncontrolled light.

請求項３に記載した発明にあっては、前記第１のＬＥＤと前記リフレクタとの間には第１のＬＥＤの光をリフレクタに向けて集光するレンズ部が配置されたので、第１のＬＥＤの光を有効にリフレクタへと導くことができ、有効に使用することが出来る。   In the invention described in claim 3, since the lens unit for condensing the light of the first LED toward the reflector is disposed between the first LED and the reflector, LED light can be effectively led to the reflector and can be used effectively.

請求項４に記載した発明にあっては、前記第１のＬＥＤと前記第２のＬＥＤとは点灯又は消灯のタイミングが異なるので、点灯により表示する機能が異なる２種類の光源を備えた車輌用灯具を小型に構成することが出来ると共に、第２のＬＥＤによる発光領域を明確に視認することが出来る。   In the invention described in claim 4, since the first LED and the second LED are turned on or off at different timings, the vehicle is provided with two types of light sources having different display functions by lighting. The lamp can be configured in a small size, and the light emitting area by the second LED can be clearly seen.

以下に、本発明車輌用灯具を実施するための最良の形態について図面を参照して説明する。   The best mode for carrying out the vehicular lamp of the present invention will be described below with reference to the drawings.

図示した車輌用灯具１は、自動車の前面又は後面の両側部に配置される標識灯であり、ランプボディ２の前面が透明な前面カバー３によって覆われている。   The illustrated vehicle lamp 1 is a marker lamp disposed on both sides of the front or rear of an automobile, and the front of the lamp body 2 is covered with a transparent front cover 3.

前記ランプボディ２は上側に位置した上ボディ２１と該上ボディ２１の下側に位置した下ボディ２２とから成る。そして、前記上ボディ２１の後側にはバックカバー４が配置されている。   The lamp body 2 includes an upper body 21 positioned on the upper side and a lower body 22 positioned on the lower side of the upper body 21. A back cover 4 is disposed on the rear side of the upper body 21.

前記上ボディ２１には、上下に離間した位置に、前後方向に貫通し、且つ、左右方向に長い貫通孔２１ａ、２１ｂが形成されている。また、上ボディ２１の前面にはリフレクタ２３が形成されている。該リフレクタ２３は上下方向に階段状に配列された複数の反射セグメント２３ａによって構成されており、該反射セグメント２３ａは下方に位置したものほど後方に位置するように前後に位置をずらされて形成されている。   The upper body 21 is formed with through-holes 21a and 21b that penetrate in the front-rear direction and are long in the left-right direction, at positions spaced vertically. A reflector 23 is formed on the front surface of the upper body 21. The reflector 23 is composed of a plurality of reflective segments 23a arranged stepwise in the vertical direction, and the reflective segment 23a is formed by shifting the position back and forth so that the lower one is positioned rearward. ing.

上ボディ２１の前記貫通孔２１ａ、２１ｂには、例えば、アクリル樹脂やポリカーボネート等の透明材料で形成され、左右方向に長い板状をした導光体５ａ、５ｂが配置され、これら導光体５ａ、５ｂは前記リフレクタ２３より前方へ突出し、その前端面は前記前面カバー３の内面近くまで延びている。そして、導光体５ａ、５ｂの前端面には、例えば、魚眼ステップ状の多数の拡散素子６が形成されている。また、前記導光体５ａ、５ｂの後端には左右方向へ階段状に位置した複数の入射端面５１が形成されており、これら入射端面５１は前記上ボディ２１の後面とほぼ同じ位置に位置し、例えば、フレネルステップ状の集光素子７が形成されている。   In the through holes 21a and 21b of the upper body 21, for example, light guides 5a and 5b that are formed of a transparent material such as acrylic resin and polycarbonate and have a long plate shape in the left-right direction are disposed. 5b projects forward from the reflector 23, and its front end surface extends to the vicinity of the inner surface of the front cover 3. A large number of fisheye step-like diffusion elements 6 are formed on the front end surfaces of the light guides 5a and 5b, for example. In addition, a plurality of incident end faces 51 are formed at the rear ends of the light guides 5a and 5b in a stepwise manner in the left-right direction, and these incident end faces 51 are located at substantially the same position as the rear face of the upper body 21. For example, the Fresnel step-shaped condensing element 7 is formed.

下ボディ２２には上面に開口した複数の配置凹部２２ａ（図２に１個のみ示す）が形成されており、該配置凹部２２ａ内に第１のＬＥＤ９が配置されている。前記配置凹部２２ａの開口部には、例えば、フレネルレンズ状の集光レンズ８が配置されている。そして、前記第１のＬＥＤ９の光軸ｘ９は上下方向に延びるように、すなわち、灯具光軸ｍｘに対してほぼ垂直な方向に延びるように位置され、前記各導光体５ａ、５ｂの主平面５２は第１のＬＥＤ９の光軸ｘ９に対してほぼ垂直を成すように位置されている。   The lower body 22 is formed with a plurality of placement recesses 22a (only one is shown in FIG. 2) opened on the upper surface, and the first LED 9 is placed in the placement recess 22a. For example, a Fresnel lens-shaped condensing lens 8 is arranged in the opening of the arrangement recess 22a. The optical axis x9 of the first LED 9 is positioned so as to extend in the vertical direction, that is, so as to extend in a direction substantially perpendicular to the lamp optical axis mx, and the main planes of the respective light guides 5a and 5b. 52 is positioned so as to be substantially perpendicular to the optical axis x9 of the first LED 9.

前記バックカバー４には前記導光体５ａ、５ｂの各入射端面５１に対向するように複数の第２のＬＥＤ１０が配置されている。そして、該第２のＬＥＤ１０の光軸ｘ１０はほぼ前後方向に延びるように位置されている。   A plurality of second LEDs 10 are arranged on the back cover 4 so as to face the incident end faces 51 of the light guides 5a and 5b. And the optical axis x10 of this 2nd LED10 is located so that it may extend in the front-back direction substantially.

第１のＬＥＤ９が点灯すると、その光は集光レンズ８によって光軸ｘ９に沿うように集光され、リフレクタ２３に向かい、該リフレクタ２３によって反射されて前面カバー３を透過して前方へ灯具光軸ｍｘに沿って照射される。このとき、２つの導光体５ａ、５ｂはその主平面５２が第１のＬＥＤ９の光軸ｘ９に対してほぼ垂直を成すように位置されているので、第１のＬＥＤ９の光は導光体５ａ、５ｂを透過してリフレクタ２３に到達する。従って、第１のＬＥＤ９の光は導光体５ａ、５ｂを介して前端面からは前方へ照射されず、そのため、前方から見ると、図４に示すように、リフレクタ２３に対応した部分（図４に梨地模様を付して示す）のみが光って見える。   When the first LED 9 is turned on, the light is collected by the condenser lens 8 along the optical axis x9, travels toward the reflector 23, is reflected by the reflector 23, passes through the front cover 3, and forwards the lamp light. Irradiation along axis mx. At this time, since the two light guides 5a and 5b are positioned so that the main plane 52 is substantially perpendicular to the optical axis x9 of the first LED 9, the light of the first LED 9 is guided to the light guide. The light passes through 5a and 5b and reaches the reflector 23. Therefore, the light of the first LED 9 is not irradiated forward from the front end face via the light guides 5a and 5b. Therefore, when viewed from the front, the portion corresponding to the reflector 23 (see FIG. 4) Only 4) is shown shining.

第２のＬＥＤ１０が点灯すると、その光は導光体５ａ、５ｂの入射端面５１から導光体５ａ、５ｂ内に入射する。このとき、集光素子７によって第２のＬＥＤ１０の光はその光軸ｘ１０に沿うように集光され、導光体５ａ、５ｂ内を前方へ向かって進む。そして、導光体５ａ、５ｂの前端面から前方へ向けて出射する。このとき、導光体５ａ、５ｂの前端面に形成された拡散素子によって拡散され、前面カバー３を透過してほぼ前方へ向けて照射される。第２のＬＥＤ１０の光は導光体５ａ、５ｂのみによって前方へ照射されるため、前方から見ると、図５に示すように、導光体５ａ、５ｂの前端面に対応した部分（図５に梨地模様を付して示す）のみが光って見える。なお、第２のＬＥＤ１０及び該第２のＬＥＤの光が入射する導光体５ａ、５ｂの入射端面５１はリフレクタ２３の背面側に位置しているので、第２のＬＥＤ１０の光のうち導光体５ａ、５ｂに入射しなかった光は、リフレクタ２３によって前方へ照射されることが阻止される。従って、第２のＬＥＤ１０の光のうち導光体に入射しなかった光が、制御されない光として前方へ出射されることを防止することが出来る。   When the second LED 10 is turned on, the light enters the light guides 5a and 5b from the incident end face 51 of the light guides 5a and 5b. At this time, the light of the second LED 10 is condensed along the optical axis x10 by the condensing element 7 and proceeds forward in the light guides 5a and 5b. And it radiates | emits ahead from the front-end surface of the light guides 5a and 5b. At this time, the light is diffused by the diffusing element formed on the front end surfaces of the light guides 5a and 5b, passes through the front cover 3, and is irradiated substantially forward. Since the light of the second LED 10 is irradiated forward only by the light guides 5a and 5b, when viewed from the front, as shown in FIG. 5, the portion corresponding to the front end face of the light guides 5a and 5b (FIG. 5). Only the item with a satin pattern on it appears to shine. Since the incident end face 51 of the second LED 10 and the light guides 5a and 5b on which the light of the second LED is incident is located on the back side of the reflector 23, the light of the second LED 10 is guided. Light that has not entered the bodies 5 a and 5 b is prevented from being irradiated forward by the reflector 23. Therefore, it is possible to prevent the light that has not entered the light guide from the light emitted from the second LED 10 from being emitted forward as uncontrolled light.

なお、前記車輌用灯具１において、第１のＬＥＤ９及び第２のＬＥＤ１０の発光色を異ならせておくことによって、それぞれ異なる表示機能を発揮することが出来る。例えば、第１のＬＥＤ９の発光色を赤色に、また、第２のＬＥＤの発光色をアンバー色に設定しておけば、第１のＬＥＤ９の点灯によってテールランプ機能を、また、第２のＬＥＤ１０の点灯によってターンシグナルランプ機能を発揮することが出来る。さらに、第１のＬＥＤ９と第２のＬＥＤ１０との点灯又は消灯のタイミングを異ならせておくことによって、第１のＬＥＤ９の点灯によってテールランプ機能を、第２のＬＥＤ１０の点灯によってストップランプ機能を発揮するなどのように、点灯により表示する機能が異なる２種類の光源を備えた車輌用灯具を小型に構成することが出来ると共に、第２のＬＥＤによる発光領域を明確に視認することが出来る。   In the vehicle lamp 1, different display functions can be exhibited by making the emission colors of the first LED 9 and the second LED 10 different. For example, if the light emission color of the first LED 9 is set to red and the light emission color of the second LED is set to amber color, the tail LED function can be achieved by turning on the first LED 9 and the second LED 10 can be turned on. Turn signal lamp function can be demonstrated by lighting. Further, by varying the timing of turning on or off the first LED 9 and the second LED 10, the tail lamp function is exhibited by the lighting of the first LED 9, and the stop lamp function is exhibited by the lighting of the second LED 10. As described above, the vehicular lamp including two types of light sources having different display functions when turned on can be configured in a small size, and the light emitting area formed by the second LED can be clearly seen.
