Title:
LED LIGHT SOURCE HIGH AND LOW BEAM INTEGRATED CAR LIGHT MODULE
Document Type and Number:
WIPO Patent Application WO/2019/100240
Kind Code:
A1
Abstract:
A light-emitting diode (LED) light source high and low beam integrated car light module: high and low beam LED circuit boards (5, 8) are respectively disposed, and a primary reflector (10) that is used for forming a low beam shape may independently form the widening of the low beam shape, while a secondary reflector (9) increases the number of light rays that form the low beam shape, part of the reflected light being used simultaneously to form an area III of the low beam shape. Light emitted by the LED light source of the low beam LED circuit board (8) is reflected by means of the first and second reflectors, and the majority of the light rays are emitted after being refracted by a lens (4) so as to form the widening (5-1) of the low beam shape on a screen, while the other small part of the light rays are emitted from the lens (4) after being reflected and refracted by a condenser so as to form a cut-off line (5-2) and the area III (5-3) in the low beam shape. Thus, no square aluminium-plated surface needs to be manufactured on a heat radiator or other parts, part processing being simple and costs being low; a small car light module may integrate an adaptive driving beam (ADB) function, and no noise is produced when switching between high and low beams.
