Abstract

Dispositif lumineux d’éclairage pour véhicule automobile doté d’un réflecteur muni d’ailettes de refroidissement L’invention concerne un dispositif lumineux d’éclairage pour véhicule automobile comportant une diode électroluminescente de puissance (323) implantée sur une plaque à circuits imprimés (324) montée sur un support (322), ainsi qu’un réflecteur (321) comportant une paroi (321A) dont l’une des faces est recouverte d’un revêtement réfléchissant apte à renvoyer les rayons lumineux émis par ladite diode (323) en direction d’un espace à illuminer ; caractérisé en ce que ladite paroi (321A) comprend une série d’ailettes de refroidissement (321C) s’étendant depuis sa face opposée à ladite face réfléchissante. Figure 2Luminous lighting device for a motor vehicle provided with a reflector provided with cooling fins The invention relates to a luminous lighting device for a motor vehicle comprising a power light-emitting diode (323) implanted on a printed circuit board (324 ) mounted on a support (322), as well as a reflector (321) comprising a wall (321A) one of the faces of which is covered with a reflective coating capable of reflecting the light rays emitted by the said diode (323) direction of a space to be illuminated; characterized in that said wall (321A) includes a series of cooling fins (321C) extending from its face opposite said reflective face.
