Intelligent lighting system for automobile lamp, automobile lamp assembly and automobile
An intelligent illuminating system for a vehicle lamp comprises a lens, a circuit board, a plurality of LED light sources on the circuit board distributed in an array, and a hollow reflector disposed between the LED light sources and the lens. The hollow reflector has reflection cavities disposed in one-to-one correspondence with the LED light sources. The reflection cavity has an incident opening, an emergent opening, and a reflection surface extending between the incident opening and the emergent opening. The LED light source is disposed at the incident opening. The emergent opening is located on a focal plane of the lens or has a defocusing amount from the focal plane of the lens.
LIGHT-EMITTING MODULE THAT IMAGES THE ILLUMINATED SURFACE OF A COLLECTOR, WITH A BLOCKER OF PARASITIC RAYS
The invention relates to a light-emitting module including a light source capable of emitting light rays, a collector with a reflective surface, an optical system configured to project a light beam by imaging a portion of the reflective surface located behind the light source, a screen located in front of the light source, with a rear face arranged so as to gather light rays which are emitted forward by the light source and are not reflected by the reflective surface. The screen includes an end face, adjacent to the rear face and facing the reflected light rays, which is configured to avoid and/or to absorb the reflected light rays.
