Motor vehicle lighting/indicator lamp with electroluminescent diodes has cooling system formed by fixed and moving radiators and air blower fan

摘要

The lamp, consisting of a housing (3) containing a series of electroluminescent diodes (LEDs) (8) mounted on a movable plate (9) to form a directional light source, has at least one diode cooler (11) comprising a fixed radiator (5) located partly close to a cold point on the vehicle, a second movable radiator (6) close to the diodes, and a fan (7) to create a convection air flow between the first and second radiators. The fixed radiator can have a portion located outside the lamp housing at the front or side of the vehicle, and the movable one can be fixed to the plate and carry the LEDs.
