A motor vehicle lamp assembly (10) having a lamp bulb (12) for emitting light and a bulb housing (14) having a light transmissive portion (16) for transmitting light from the lamp bulb to an illumination zone. The housing is coated with a coating material (60), which covers a selected region (32, 34, 36) of the light transmissive portion of the housing. The coating material is electrically energized to alter an amount of light transmitted from the bulb to the illumination zone. A drive circuit (30) electrically coupled to the coating material energizes the coating material to control a light output from the lamp assembly.
Cette invention concerne un ensemble lampe (10) pour véhicule comportant une ampoule (12) qui émet de la lumière et une boîtier d'ampoule (14) doté d'une partie de transmission de la lumière (16) qui transmet la lumière de l'ampoule à une zone d'éclairage. Ce boîtier est enduit d'un matériau de revêtement (60) qui recouvre une région déterminée (32, 34, 36) de la partie de transmission de la lumière dudit boîtier. Lorsqu'il est excité électriquement, le matériau de revêtement modifie la quantité de lumière transmise de l'ampoule à la zone d'éclairage. Un circuit de commande (30) couplé électriquement au matériau de revêtement excite ce dernier, ce qui permet de moduler la quantité de lumière émise par l'ensemble lampe.
