LED LIGHT SOURCE SURFACE LIGHT-EMITTING MODULE, VEHICLE LAMP APPLYING SAME AND ASSEMBLY METHOD
Document Type and Number:
WIPO Patent Application WO/2019/227688
Kind Code:
A1
Abstract:
Disclosed are an LED light source surface light-emitting module, a vehicle lamp applying same and an assembly method. The LED light source surface light-emitting module comprises a back plate (1), a light guide plate (2) and an optical film (3) which are successively arranged from back to front. One side of the light guide plate (2) is provided with an LED light source (4) and a PCB. A plurality of concave/convex microstructures are arranged at intervals on the light guide plate (2). The light-emitting module can achieve a uniform surface light emission effect, can have an ultra-thin (about 2 mm) structure, and can be made to have a curved surface, so that the technical problem that an existing LED light-emitting module cannot realize uniform lighting and cannot be used as a brake lamp, a turn signal lamp, etc. to have a high brightness function can be solved.
