Title
(EN) LED HEADLAMP SYSTEM
(FR) SYSTEME DE LAMPE DE PROJECTEUR A DIODES
Abstract
(EN)
A vehicle headlamp (20) includes a first planar row of low and high beam LED light sources (22); a first primary optical light guide receiving low and high beam light from the LEDs; a First secondary optical light guide receiving and focusing collimated low and high beam light from the first primary light guide as a combination of low and high beam hot spots; a second planar array of LED light sources having low and high beam LEDs (24); a second primary optical light guide receiving and collimating low and high beam light from the second LED light sources; a second secondary optical light guide receiving said collimated low and high beam light and spreading the light as a combination of low and high beam spread pattern; a housing (60) to mechanically support the LED arrays, the first primary optical light guide, the first secondary optical light guide, the second primary optical light guide and the second secondary optical light guide.

La présente invention concerne une lampe de projecteur d'automobile. Cette lampe est constituée de plusieurs éléments. Une première matrice plane réunit des sources de lumière à diodes destinées aux faisceaux bas et haut. Un premier guide optique primaire reçoit depuis les diodes électroluminescentes la lumière destinée aux faisceaux bas et haut. Un premier guide optique secondaire reçoit et focalise la lumière collimatée des faisceaux haut et bas provenant du premier guide optique primaire sous forme d'une combinaison des points chauds des faisceaux bas et haut. Une deuxième matrice plane réunit des sources de lumière à diodes destinées aux faisceaux bas et haut. Un deuxième guide optique primaire reçoit et collimate la lumière destinée aux faisceaux bas et haut provenant des deuxièmes sources de lumière à diodes. Un deuxième guide optique secondaire reçoit ladite lumière collimatée des faisceaux bas et haut et répartit la lumière sous forme d'une combinaison de structures de répartition des faisceaux bas et haut. Un carter sert de support mécanique aux matrices de diodes électroluminescentes, à la première optique primaire, à la première optique secondaire, au deuxième guide optique primaire et à la deuxième optique secondaire.
