Description

本発明は、ハウジングの内部に機能が異なる複数の灯具ユニットを備えた車両用灯具に関する。   The present invention relates to a vehicular lamp including a plurality of lamp units having different functions inside a housing.

従来、図５に示すように、ハウジング５１の内部に、ロービームランプ５２Ａおよびハイビームランプ５２Ｂを備えたヘッドランプ・ユニット５２と、反射鏡５３Ａおよび光源５３Ｂを備えたターンシグナルランプ・ユニット５３と、レンズ５４Ａおよび光源５４Ｂを備えたクリアランスランプ・ユニット５４とを設置した車両用灯具５０が知られている。しかし、この灯具５０によると、３つの灯具ユニット５２，５３，５４がハウジング５１の内部に独自のスペースを占有するため、灯具５０の全体が大型化するという問題点があった。   Conventionally, as shown in FIG. 5, inside a housing 51, a headlamp unit 52 having a low beam lamp 52A and a high beam lamp 52B, a turn signal lamp unit 53 having a reflecting mirror 53A and a light source 53B, and a lens A vehicular lamp 50 having a clearance lamp unit 54 provided with 54A and a light source 54B is known. However, according to the lamp 50, the three lamp units 52, 53, and 54 occupy a unique space inside the housing 51, so that there is a problem that the entire lamp 50 is enlarged.

そこで、従来、機能が異なる２つの灯具ユニットをハウジングの前後に設置して、灯具全体を小型に構成する技術が提案されている。例えば、特許文献１の車両用灯具は、ハウジングの前後に導光部材と反射鏡とを設置し、導光部材に第１光源を付設し、反射鏡に第２光源を付設し、導光部材と第１光源とでテールランプ・ユニットを構成し、反射鏡と第２光源とでストップランプ・ユニットを構成している。   Therefore, conventionally, a technique has been proposed in which two lamp units having different functions are installed on the front and rear sides of the housing to make the entire lamp compact. For example, the vehicular lamp disclosed in Patent Document 1 has a light guide member and a reflecting mirror installed before and after the housing, a first light source attached to the light guide member, and a second light source attached to the reflector. And the first light source constitute a tail lamp unit, and the reflecting mirror and the second light source constitute a stop lamp unit.

ところが、従来の車両用灯具によると、ハウジングの後側に設置されたストップランプ・ユニットの照明光がテールランプ・ユニットの導光部材を透過した後に灯具前方へ照射されるため、導光部材における光の拡散によって、ストップランプの配光パターンがぼやけるという問題点があった。このため、前後の灯具ユニットの間に専用の光学部品を介在させて、配光パターンの輪郭を整える必要があった。   However, according to the conventional vehicular lamp, the illumination light of the stop lamp unit installed on the rear side of the housing is irradiated to the front of the lamp after passing through the light guide member of the tail lamp unit. There is a problem that the light distribution pattern of the stop lamp is blurred due to the diffusion of light. For this reason, it has been necessary to arrange a special optical component between the front and rear lamp units to adjust the contour of the light distribution pattern.

本発明は、上記問題点に着目してなされたものであり、その目的は、配光パターンの輪郭を不明瞭にすることなく、異なる機能の灯具ユニットをコンパクトな形態で配置できる車両用灯具を提供することにある。   The present invention has been made paying attention to the above problems, and an object of the present invention is to provide a vehicular lamp in which lamp units having different functions can be arranged in a compact form without obscure the outline of the light distribution pattern.

The unit 13 is equipped with a daylight running lamp (DRL) unit 14 and a turn signal lamp (TSL) unit 15.

ＤＲＬ・ユニット１４は、本発明の第１灯具ユニットであり、第１光源１４Ａからの光で導光体１４Ｂを面発光させるように構成されている。第１光源１４Ａは、導光体１４Ｂの左右両側縁に沿って複数のＬＥＤを備え、各ＬＥＤからの白色光を導光体１４Ｂの両端面から内部に向けて出射する。   The DRL unit 14 is the first lamp unit of the present invention, and is configured to cause the light guide 14B to emit light with light from the first light source 14A. The first light source 14A includes a plurality of LEDs along the left and right edges of the light guide 14B, and emits white light from each LED toward the inside from both end faces of the light guide 14B.

導光体１４Ｂは、アウターレンズ１２に相対するインナーレンズとして機能するように、透明樹脂材料でハウジング１１の前面開口部を覆う大きさに形成されている。そして、導光体１４Ｂの一部に、ＨＬ・ユニット１３のロービームランプ１３Ａとハイビームランプ１３Ｂとが設けられている。   The light guide 14 </ b> B is formed in a size that covers the front opening of the housing 11 with a transparent resin material so as to function as an inner lens facing the outer lens 12. A low beam lamp 13A and a high beam lamp 13B of the HL unit 13 are provided in a part of the light guide 14B.

ＴＳＬ・ユニット１５は、本発明の第２灯具ユニットであり、左右に３つの灯具ユニットがそれぞれ第２光源１５Ａからの光を反射鏡１５Ｂに反射させるように構成されている。第２光源１５Ａは、反射鏡１５Ｂの内側に一つのＬＥＤを備え、ＬＥＤからの黄色光を反射鏡１５Ｂのパラボラ反射面１６に向けて出射する。   The TSL unit 15 is the second lamp unit of the present invention, and is configured such that the three lamp units on the left and right respectively reflect the light from the second light source 15A to the reflecting mirror 15B. The second light source 15A includes one LED inside the reflecting mirror 15B, and emits yellow light from the LED toward the parabolic reflecting surface 16 of the reflecting mirror 15B.

反射鏡１５Ｂは導光体１４Ｂの背後に配置され、導光体１４Ｂに反射鏡１５Ｂからの光を通過させる開口部１７が形成されている。灯具前方から見て、開口部１７は反射鏡１５Ｂよりも小さな面積で形成され、パラボラ反射面１６が開口部１７より灯具前方へ露出する部分１６ａ（図１参照）と、灯具後方から導光体１４Ｂに重なり合う部分１６ｂとを備えている。   The reflecting mirror 15B is disposed behind the light guide 14B, and an opening 17 through which light from the reflecting mirror 15B passes is formed in the light guide 14B.

導光体１４Ｂの裏面において、開口部１７の周縁には光輝部１８が凹設され、第２光源１５Ａの点灯時に反射鏡１５Ｂからの光を集めて曲線または直線のライン状に発光する。そして、ＴＳＬ・ユニット１５が、ＤＲＬ・ユニット１４の白色光よりも高い輝度の黄色点滅光を、光輝部１８の内側において開口部１７に通過させ、車両前方へ照射し、減光照明を行うＤＲＬ・ユニット１４とは異なる機能の方向指示照明を行うようになっている。   On the back surface of the light guide 14B, a bright portion 18 is recessed in the periphery of the opening 17, and when the second light source 15A is turned on, the light from the reflecting mirror 15B is collected and emitted in a curved or straight line shape. Then, the TSL unit 15 causes the yellow blinking light having a luminance higher than that of the white light of the DRL unit 14 to pass through the opening 17 inside the bright portion 18, and irradiates the vehicle forward, thereby performing dimming illumination. -The direction indication illumination of the function different from the unit 14 is performed.

従って、実施例１の車両用前照灯１０によれば、ＤＲＬ・ユニット１４の導光体１４ＢとＴＳＬ・ユニット１５の反射鏡１５Ｂをハウジング１１の前後に配置し、灯具全体を小型に構成することができる。また、ＴＳＬ・ユニット１５の反射光を導光体１４Ｂの開口部１７に素通りさせて灯具前方へ照射するため、導光体１４Ｂによる光の拡散を防止し、方向指示用の配光パターンを高輝度の黄色光によって明瞭に形成することもできる。   Therefore, according to the vehicle headlamp 10 of the first embodiment, the light guide 14B of the DRL unit 14 and the reflecting mirror 15B of the TSL unit 15 are arranged before and after the housing 11, and the entire lamp is configured to be small. be able to. Further, since the reflected light of the TSL unit 15 passes through the opening 17 of the light guide 14B and is irradiated to the front of the lamp, the light diffusion by the light guide 14B is prevented, and the direction distribution light distribution pattern is increased. It can also be clearly formed by bright yellow light.

実施例２の車両用尾灯２０は、図３，図４に示すように、ハウジング２１の内部に、第１灯具ユニットとしてのテールランプ（ＴＬ）・ユニット２２と、第２灯具ユニットとしてのストップランプ（ＳＬ）・ユニット２３とを備えている。そして、ＴＬ・ユニット２２が第１光源２２Ａからの光で導光体２２Ｂを面発光させ、ＳＬ・ユニット２３が第２光源２３Ａからの光を反射鏡２３Ｂに反射させるようになっている。   As shown in FIGS. 3 and 4, the vehicle tail lamp 20 of the second embodiment includes a tail lamp (TL) unit 22 as a first lamp unit and a stop lamp (second lamp unit) as a first lamp unit. SL) unit 23. The TL unit 22 causes the light guide 22B to emit light with the light from the first light source 22A, and the SL unit 23 reflects the light from the second light source 23A to the reflecting mirror 23B.

ＴＬ・ユニット２２の第１光源２２Ａは、導光体２２Ｂの左右に複数のＬＥＤを備え、各ＬＥＤからの光を導光体２２Ｂの両側面から内部に向けて出射する。導光体２２Ｂは赤色の透明樹脂材料で形成され、表面に第１光源２２Ａからの光の一部を点状に発光させるための複数のステップ２４が刻設され、中央に円形または四角形の開口部２５が透設されている。   The first light source 22A of the TL unit 22 includes a plurality of LEDs on the left and right sides of the light guide 22B, and emits light from each LED toward the inside from both side surfaces of the light guide 22B. The light guide 22B is formed of a red transparent resin material, and a plurality of steps 24 for emitting a part of light from the first light source 22A in a dot shape are formed on the surface, and a circular or square opening is formed in the center. The part 25 is transparently provided.

ＳＬ・ユニット２３の第２光源２３Ａは、反射鏡２３Ｂの上側または下側に複数のＬＥＤを備え、ＬＥＤからの赤色光を反射鏡２３Ｂの段付き反射面２６（図４参照）に向けて出射する。反射鏡２３Ｂは導光体２２Ｂの背後に配置され、段付き反射面２６で反射した赤色光を開口部２５に通過させる。灯具前方から見て、開口部２５は反射鏡２３Ｂよりも小さな面積で形成され、段付き反射面２６に開口部２５より灯具前方へ露出する部分２６ａ（図３参照）と、灯具後方から導光体２２Ｂに重なり合う部分２６ｂとが設けられている。   The second light source 23A of the SL unit 23 includes a plurality of LEDs above or below the reflecting mirror 23B, and emits red light from the LEDs toward the stepped reflecting surface 26 (see FIG. 4) of the reflecting mirror 23B. To do. The reflecting mirror 23B is disposed behind the light guide 22B, and allows the red light reflected by the stepped reflecting surface 26 to pass through the opening 25. When viewed from the front of the lamp, the opening 25 is formed with a smaller area than the reflecting mirror 23B, and a portion 26a (see FIG. 3) exposed to the front of the lamp from the opening 25 on the stepped reflection surface 26 and guided from the rear of the lamp. A portion 26b overlapping the body 22B is provided.

導光体２２Ｂの裏面において、開口部２５の周縁には光輝部２８が凹設され、第２光源２３Ａの点灯時に反射鏡２３Ｂからの光を集めてライン状に発光する。そして、ＳＬ・ユニット２３が、ＴＬ・ユニット２２よりも高い輝度の赤色光を、光輝部２８の内側において開口部２５に通過させ、灯具カバー２７を介して車両後方へ出射し、夜間確認照明を行うＴＬ・ユニット１４とは異なる機能の停車表示照明を行うようになっている。   On the back surface of the light guide 22B, a bright portion 28 is recessed at the periphery of the opening 25, and when the second light source 23A is turned on, the light from the reflecting mirror 23B is collected and emitted in a line shape. Then, the SL unit 23 passes red light having higher brightness than that of the TL unit 22 through the opening 25 on the inner side of the bright part 28, and emits the light to the rear of the vehicle through the lamp cover 27, and the night confirmation illumination is performed. The stop display illumination having a function different from that of the TL unit 14 to be performed is performed.

従って、実施例２の車両用尾灯２０によれば、ＴＬ・ユニット２２の導光体２２ＢとＳＬ・ユニット２３の反射鏡２３Ｂをハウジング２１の前後に配置し、灯具全体を小型に構成することができる。また、ＳＬ・ユニット２３の反射光を導光体２２Ｂの開口部２５に素通りさせて灯具前方へ照射するため、導光体２２Ｂによる光の拡散を防止し、停車表示用の配光パターンを明瞭な輪郭で形成することもできる。   Therefore, according to the vehicle tail lamp 20 of the second embodiment, the light guide 22B of the TL unit 22 and the reflecting mirror 23B of the SL unit 23 are arranged in front and rear of the housing 21, and the entire lamp can be configured to be small. it can. In addition, since the reflected light of the SL unit 23 passes through the opening 25 of the light guide 22B and irradiates the front of the lamp, light diffusion by the light guide 22B is prevented, and the light distribution pattern for stopping display is clear. It can also be formed with a simple contour.
