Abstract
Description
Technical Field
[0001] The utility model relates to a surface 2.0 (surface led II) lamp structure, in particular to a lamp structure for optimizing lighting effects. Background Art
[0002] At present, the light sources on the market are basically realized by LED + light guide plate 3 except O-LED (such as Figure 1 ), when the black trim 1 is blocked, there will be no obvious bright spot at the end of the light guide plate. However, with the rapid development of the shape of car lights, surface2.0 (surfaceled Ⅱ, a surface led light source technology for car lights) came into being. The main feature is that the turn signal is added to the position light structure, and there is no blockage between the turn signal and the position light guide plate, so there will be an obvious bright spot at the end of the light guide plate. At present, the surface2.0 optical system has just emerged. This system has both a three-dimensional effect and saves lamp space and lamp cost. It will be widely used in future lamps, so an optimized structure is needed. Utility Model Content
