Title (EN) VEHICULAR LIGHTING FIXTURE
(FR) APPAREIL D'ÉCLAIRAGE DE VÉHICULE
(JA) 車両用灯具
Abstract:
(EN) This vehicular lighting fixture illuminates an area ahead of a vehicle, and is provided with a parallel light illumination device for illuminating parallel light, and a projection optical system for projecting forward the parallel light illuminated from the parallel light illumination device, wherein the focal length of a horizontal component of the projection optical system is shorter than the focal length of a vertical component thereof.
(FR) La présente invention concerne un appareil d'éclairage de véhicule éclairant une zone devant un véhicule, et pourvu d'un dispositif d'émission de lumière parallèle pour émettre une lumière parallèle, et d'un système optique de projection pour projeter vers l'avant la lumière parallèle émise par le dispositif d'émission de lumière parallèle, la longueur focale d'une composante horizontale du système optique de projection étant plus courte que la longueur focale d'une composante verticale de celui-ci.
(JA) 車両用灯具は、車両の前方を照射する車両用灯具であって、平行光を照射する平行光照射装置と、平行光照射装置から照射された平行光を前方に投影する投影光学系と、を備え、投影光学系は、水平成分の焦点距離が、鉛直成分の焦点距離より短い。
