Description

車両用灯具Vehicle lighting
　本開示は、車両用灯具に関する。 This disclosure relates to vehicle lamps.
　特許文献１には、上下方向に延びる縦長の発光部と、当該縦長の発光部の長手方向に対して直交するように車幅方向に延びる横長の発光部とを備えるヘッドランプが開示されている。かかるヘッドランプによれば、縦長の発光部によって車両前方近くから遠くまで光を照射でき、横長の発光部によって縦長の発光部の光が届きにくい路肩に向けて光が照射できる、とされている。 Patent Document 1 discloses a headlamp including a vertically long light emitting portion extending in the vertical direction and a horizontally long light emitting portion extending in the vehicle width direction so as to be orthogonal to the longitudinal direction of the vertically long light emitting portion. .. According to such a headlamp, the vertically long light emitting portion can irradiate light from near the front of the vehicle to a long distance, and the horizontally long light emitting portion can irradiate the light toward the shoulder where the light of the vertically long light emitting portion is difficult to reach. ..
特開２０１９－５３９６５号公報Japanese Unexamined Patent Publication No. 2019-53965
　特許文献１が開示するヘッドランプでは、横長の発光部の上下に二つのハイビーム用発光部が配置され、縦長の発光部、横長の発光部及び二つのハイビーム用発光部が一つのアウターレンズで覆われるので、縦長の発光部の光と横長の発光部の光を区別することなくアウターレンズを通り車両前方を照射する。 In the headlamp disclosed in Patent Document 1, two high beam light emitting parts are arranged above and below the horizontally long light emitting part, and the vertically long light emitting part, the horizontally long light emitting part and the two high beam light emitting parts are covered with one outer lens. Therefore, it illuminates the front of the vehicle through the outer lens without distinguishing between the light of the vertically long light emitting part and the light of the horizontally long light emitting part.
　一方、車両の幅方向両側に設けられた縦長の発光部から照射される光は夜間に車両の幅を強調するので、車両の幅方向両側に縦長の発光部を備える車両は夜間に実際よりも近くに見える。これにより、対向車の運転者や歩行者は夜間に車両の幅方向両側に縦長の発光部を備える車両の接近をいち早く気づくことができる。 On the other hand, since the light emitted from the vertically long light emitting parts provided on both sides in the width direction of the vehicle emphasizes the width of the vehicle at night, a vehicle having vertically long light emitting parts on both sides in the width direction of the vehicle is more than the actual one at night. It looks close. As a result, the driver or pedestrian of the oncoming vehicle can quickly notice the approach of the vehicle having vertically long light emitting portions on both sides in the width direction of the vehicle at night.
　上述の事情に鑑みて、本発明の少なくとも一実施形態は、夜間に車両の幅をより強調できる車両用灯具を提供することを目的とする。 In view of the above circumstances, at least one embodiment of the present invention aims to provide a vehicle lamp that can further emphasize the width of the vehicle at night.
　本発明の少なくとも一実施形態に係る車両用灯具は、車両の幅方向外側に設置され、前記車両の幅方向に沿って延びる横長の第１発光部と、前記第１発光部の外側から前記車両の上下方向に沿って延びる縦長の第２発光部と、前記第１発光部及び前記第２発光部の前面を覆い、前記第１発光部及び前記第２発光部の光を配光するアウターレンズとを備え、前記アウターレンズは、前記第１発光部の長手方向に沿って延びる第１部分と当該第１部分の外端部において前記第２発光部の長手方向に沿って延びる第２部分とを有する。 The vehicle lighting fixture according to at least one embodiment of the present invention is installed on the outside in the width direction of the vehicle, and has a horizontally long first light emitting portion extending along the width direction of the vehicle and the vehicle from the outside of the first light emitting portion. An outer lens that covers the front surface of the first light emitting part and the second light emitting part and distributes the light of the first light emitting part and the second light emitting part. The outer lens includes a first portion extending along the longitudinal direction of the first light emitting portion and a second portion extending along the longitudinal direction of the second light emitting portion at the outer end portion of the first portion. Has.
　上記の構成によれば、アウターレンズは、第１発光部の長手方向に沿って延びる第１部分と第２発光部の長手方向に沿って延びる第２部分とを有する輪郭をなす。すなわち、本発明のアウターレンズは、発光部に沿った形状を呈し、当該発光部と同様の輪郭を有している。その結果、発光部に沿うことなく当該発光部とは異なる形状を有するアウターレンズと比較して、本発明のアウターレンズによれば発光部の集光性能が高まるので、縦長の第２発光部が照射する光が夜間に鮮明に現れて車両の幅を強調する。これにより、本実施形態にかかる車両用灯具が設置された車両は夜間に実際よりも近く見える（このような視覚的効果を本願において「ワイドスパン効果」という）。この結果、本実施形態に係る車両用灯具が設置された車両の対向車の運転者や歩行者は車両の接近を夜間にいち早く気づくことができる。 According to the above configuration, the outer lens has a contour having a first portion extending along the longitudinal direction of the first light emitting portion and a second portion extending along the longitudinal direction of the second light emitting portion. That is, the outer lens of the present invention has a shape along the light emitting portion and has the same contour as the light emitting portion. As a result, according to the outer lens of the present invention, the light collecting performance of the light emitting portion is improved as compared with the outer lens having a shape different from that of the light emitting portion without following the light emitting portion, so that the vertically long second light emitting portion is formed. The shining light appears clearly at night, emphasizing the width of the vehicle. As a result, the vehicle on which the vehicle lighting fixture according to the present embodiment is installed looks closer than it actually is at night (such a visual effect is referred to as a "wide span effect" in the present application). As a result, the driver or pedestrian of the oncoming vehicle of the vehicle on which the vehicle lighting equipment according to the present embodiment is installed can quickly notice the approach of the vehicle at night.
　本発明の一実施形態では、前記第１発光部にはハイビームユニットが配置され、前記第２発光部には前記ハイビームユニットよりも光照射距離が短いロービームユニットが配置される。 In one embodiment of the present invention, a high beam unit is arranged in the first light emitting unit, and a low beam unit having a shorter light irradiation distance than the high beam unit is arranged in the second light emitting unit.
　上記の構成によれば、第１発光部にはハイビームユニットが配置されるので、第１発光部の上方域及び下方域にハイビームユニットを設置する必要がなく、第１発光部の上方域又は下方域の少なくとも一方に、第１発光部の長手方向に沿って延びる一辺と第２発光部の長手方向に沿って延びる一辺とが交差する輪郭を設けることができる。また、第２発光部にはハイビームユニットよりも光照射距離が短いロービームユニットが配置されるので、対向車の有無にかかわらず第２発光部から夜間に光が照射され、当該第２発光部に沿うように延びる本発明のアウターレンズ（第２部分）の形状と相まって常時ワイドスパン効果が発揮される。これにより、本実施形態に係る車両用灯具が設置された車両の運転者や歩行者は車両の接近を夜間にいち早く気づくことができる。 According to the above configuration, since the high beam unit is arranged in the first light emitting portion, it is not necessary to install the high beam unit in the upper region and the lower region of the first light emitting portion, and the upper region or the lower region of the first light emitting portion is not required. At least one of the regions may be provided with a contour in which one side extending along the longitudinal direction of the first light emitting portion and one side extending along the longitudinal direction of the second light emitting portion intersect. Further, since the low beam unit having a shorter light irradiation distance than the high beam unit is arranged in the second light emitting unit, light is emitted from the second light emitting unit at night regardless of the presence or absence of an oncoming vehicle, and the second light emitting unit is irradiated with light at night. Combined with the shape of the outer lens (second part) of the present invention extending along the line, the wide span effect is always exhibited. As a result, the driver or pedestrian of the vehicle in which the vehicle lighting equipment according to the present embodiment is installed can quickly notice the approach of the vehicle at night.
　本発明の一実施形態では、前記アウターレンズの前記第１部分及び前記第２部分は、前記車両の幅方向外側に設置された昼間走行用灯具の直下に配置される。 In one embodiment of the present invention, the first portion and the second portion of the outer lens are arranged directly below the daytime traveling lamps installed on the outer side in the width direction of the vehicle.
　上記の構成によれば、アウターレンズの第１部分及び第２部分が昼間走行用灯具とデザイン上の統一を図ることができる。 According to the above configuration, the first part and the second part of the outer lens can be unified in design with the daytime running lamp.
　本発明の一実施形態では、前記アウターレンズの前記第１部分は、前記昼間走行用灯具と平行となるように設置される。 In one embodiment of the present invention, the first portion of the outer lens is installed so as to be parallel to the daytime lamp.
　上記の構成によれば、アウターレンズの第１部分が昼間走行用灯具とデザイン上の統一を図ることができる。 According to the above configuration, the first part of the outer lens can be unified in design with the daytime lamp.
　本発明の一実施形態では、前記車両は、車両前部に設けられたラジエータグリルと、前記ラジエータグリルの両側に対をなし、前記車両の幅方向外側に向かうにしたがって前記車両の後方に漸次後退する傾斜面を有する凹部を有し、前記第１発光部が前記凹部の前記傾斜面に位置するように設置される。 In one embodiment of the present invention, the vehicle is paired with a radiator grill provided at the front of the vehicle on both sides of the radiator grill, and gradually retreats to the rear of the vehicle as it goes outward in the width direction of the vehicle. It has a recess having an inclined surface, and the first light emitting portion is installed so as to be located on the inclined surface of the recess.
　上記の構成によれば、第１発光部が凹部の傾斜面に位置するように配置されるので、車両用灯具の前面に付着した水滴やゴミが走行風によって除去されやすい。 According to the above configuration, since the first light emitting portion is arranged so as to be located on the inclined surface of the recess, water droplets and dust adhering to the front surface of the vehicle lamp can be easily removed by the running wind.
　本発明の少なくとも一実施形態によれば、縦長の第２発光部が照射する光が夜間に鮮明に現れて車両の幅を強調する。これにより、本実施形態に係る車両用灯具が設置された車両は夜間に実際よりも近く見える。この結果、本実施形態に係る車両用灯具が設置された車両の対向車の運転者や歩行者は車両の接近を夜間にいち早く気づくことができる。 According to at least one embodiment of the present invention, the light emitted by the vertically long second light emitting unit appears clearly at night to emphasize the width of the vehicle. As a result, the vehicle on which the vehicle lighting fixture according to the present embodiment is installed looks closer than it actually is at night. As a result, the driver or pedestrian of the oncoming vehicle of the vehicle on which the vehicle lighting equipment according to the present embodiment is installed can quickly notice the approach of the vehicle at night.
