Abstract

La présente invention concerne un module de lampe à LED pour véhicule comprenant : une partie de base couplée de manière amovible à un trou de montage de lampe d'un boîtier de feu avant de véhicule; une partie support de conduction de chaleur de source de lumière réalisée au niveau du côté avant de la partie de base et dotée d'une paire de surfaces de couplage de source de lumière secondaire espacées l'une de l'autre par rapport à leur centre pendant une projection plane, et une surface de couplage de source de lumière centrale formée entre les deux surfaces de couplage de source de lumière secondaire; une source de lumière à LED supportée respectivement par chacune des surfaces de couplage de source de lumière; et un corps de dissipation de chaleur disposé sur le côté arrière de l'élément de base de manière à évacuer la chaleur transférée depuis la partie support de conduction de chaleur de source de lumière. Par conséquent, la présente invention réalise un module de lampe à LED pour véhicule qui met en œuvre simultanément presque la même forme de distribution de lumière que celle d'une lampe à halogène et ayant une luminance élevée. La présente invention concerne en outre un module de lampe à LED pour véhicule capable d'empêcher l'éblouissement du conducteur d'un véhicule venant en sens inverse, du fait que la réflexion diffuse est réduite au minimum.
