Problems solved by technology
However, this technical solution is difficult to take into account the central brightness of the illumination spot and the width of the illumination spot, resulting in either the center of the illumination spot being dark, or the left and right irradiation range of the light spot being narrow
To solve this problem, a technical solution is to set up multiple different light sources, which are responsible for the central brightness of the illumination spot and the width of the spot, but this technical solution leads to a bloated structure of the car light, which is not conducive to compact design

The invention discloses a light source module. The light source module comprises a light source, a light condensing element and a convex lens, wherein the light source is used for emitting light; thelight condensing element is arranged on the light emitting side of the light source, and comprises a first incident surface and a reflecting surface; the light condensing element is used for converging the first part of light passing through the first incident surface to a first converging point and is used for converging the second part of light passing through the reflecting surface to a secondconverging point; the convex lens is arranged on the light emitting side of the light condensing element, wherein the front focal point of the convex lens is located on the first converging point, andthe second converging point is located between the first converging point and the convex lens; and the convex lens is used for projecting the light rays of the first converging point and the second converging point outwards. By means of the mode, light distribution control on different areas of emergent light spots can be realized through the compact optical design, and the light emitting effectof the light source module is improved.
Description
technical field [0001] The present application relates to the field of lighting technology, in particular to a light source module. Background technique [0002] With the improvement of people's living standards, more and more people have joined the ranks of car buyers, which directly promotes the development of the automobile industry. Major automobile companies have launched products with different configurations and different prices to meet different needs. consumer. In the automotive market, the shape of the car is becoming more and more important, and the headlight module, which is the "eye" of the car, is naturally more valued. [0003] Generally, the light source module of a car uses an ellipsoidal reflector to reflect the light emitted by the light source, and projects the light through a lens. However, it is difficult for this technical solution to take into account both the central brightness of the illumination spot and the width of the illumination spot, result...
