Title
(EN) VEHICLE LAMP FITTING
(FR) RACCORD DE LAMPE DE VÉHICULE
Abstract
(EN) Problem: To provide a vehicle lamp fitting in which regularity of the strength or weakness of the emitted light is maintained and deterioration of appearance is suppressed. Solution: A vehicle lamp fitting 10 comprises a light guide 11 which guides light from an LED light source 12 and an LED light source 13, the light guide 11 having entrance surfaces 110, 111, emission surfaces R1 to R3, and an internally reflecting surface 17 which causes light that has entered through the entrance surfaces 110, 111 to be reflected, and the internally reflecting surface 17 comprises a reflecting surface 141 which is provided in a first region 14 and which emits light from the LED light source 12 in a forward direction, a reflecting surface 151 which is provided in a second region 15 and which emits light from the LED light source 13 in the forward direction, and a reflecting surface 161 which is formed in a third region 16 between the first region 14 and the second region 15 and which limits the light intensity with which light from the LED light sources 12, 13 is emitted in the forward direction from the emission surface R3.

(FR) La présente invention vise à fournir un raccord de lampe de véhicule dans lequel une régularité de l'intensité ou de la faiblesse de la lumière émise est maintenue et une détérioration d'apparence est supprimée. A cet effet, l'invention concerne un raccord de lampe de véhicule (10) qui comprend un guide de lumière (11) qui guide une lumière provenant d'une source de lumière à DEL (12) et d'une source de lumière à DEL (13), le guide de lumière (11) ayant des surfaces d'entrée (110, 111), des surfaces d'émission R1 à R3, et une surface réfléchissante de manière interne (17) qui amène une lumière qui est entrée par l'intermédiaire des surfaces d'entrée (110, 111) à être réfléchie, et la surface réfléchissante de manière interne (17) comprend une surface réfléchissante (141) qui est située dans une première région (14) et qui émet une lumière provenant de la source de lumière à DEL (12) dans une direction avant, une surface réfléchissante (151) qui est située dans une deuxième région (15) et qui émet une lumière provenant de la source de lumière à DEL (13) dans la direction avant, et une surface réfléchissante (161) qui est formée dans une troisième région (16) entre la première région (14) et la deuxième région (15) et qui limite l'intensité lumineuse avec laquelle une lumière provenant des sources de lumière à DEL (12, 13) est émise dans la direction avant à partir de la surface d'émission R3.
