Title (EN) LED-BASED LAMP
(FR) LAMPE À DIODES ÉLECTROLUMINESCENTES
Abstract:
(EN) A lamp device for low-beam automotive applications has a reflector and a module with LEDs. The module is positioned with regard to the reflector so that the reflector generates at an exit interface of the lamp a beam from light emitted by the LEDs. The module comprises light re-directing means adjacent the LEDs and operative to direct a portion of the light incident on the means to the reflector. This configuration enables to recover light rays that would otherwise not contribute to illuminating the road surface.
(FR) La présente invention a trait à un dispositif de lampe destiné aux applications automobiles de feu de croisement qui est équipé d’un réflecteur et d’un module pourvu de diodes électroluminescentes. Le module est placé par rapport au réflecteur de manière à ce que le réflecteur génère à une interface de sortie de la lampe un faisceau provenant de la lumière émise par les diodes électroluminescentes. Le module comprend un moyen de réorientation de lumière adjacent aux diodes électroluminescentes et fonctionnant de manière à diriger une partie de la lumière incidente sur le moyen vers le réflecteur. Cette configuration permet de récupérer les rayons lumineux qui autrement ne contribueraient pas à l’éclairage de la surface de la route.
