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.
1. An intelligent illuminating system for a vehicle lamp, comprising:
a lens;
a circuit board ( 4 ),
a plurality of light emitting diode (LED) light sources ( 3 ) disposed on the circuit board ( 4 ) distributed in an array;
