Detailed ways

In order to enable those of ordinary skill in the art to fully understand the technical solutions and beneficial effects of the present invention, further description is provided below with reference to specific embodiments and drawings.

Prior to this application, the light sources on the side of the high and low beam modules were blocked by the black module bezel, resulting in a waste of this light. In order to effectively utilize this light, the inventor team tried to improve the module bezel from black to a black + transparent (additional light-transmitting area) two-color bezel, and added optical patterns and leather patterns to the inner and outer surfaces of the light-transmitting area. This solution uses the light source on the side of the high and low beam module to light up the two-color module bezel without affecting the high and low beam functions of the headlight, creating a unique position light lighting effect. The improved position light not only meets the customer's unique appearance design requirements, but also achieves very good results with relatively small changes and low costs.

As shown in Figures 1-4, the headlight mainly includes an outer lens 1, a high and low beam module 2, a module bracket 3, a two-color module bezel 4, and a lamp housing 5. The connection relationship of each component is as follows: the high and low beam module 2 is fixedly connected to the module bracket 3 by screws, the module bracket 3 is clamped with the lamp housing 5 through the module bracket fixing kit, the two-color module bezel 4 is fixedly connected to the high and low beam module 2 by buckles, and the lamp housing 5 is encapsulated and fixed with the outer lens 1 by sealant, thereby forming a complete headlight. The two-color module bezel 4 is integrally formed with black plastic and transparent plastic, wherein the transparent plastic forms a light-transmitting area, which is located outside or around the high and low beam module 2. Optical patterns 10 and leather grains 9 are designed on the inner and outer surfaces of the light-transmitting area of the two-color module bezel 4, respectively, and light can form a uniform lighting effect after passing through these optical patterns and leather grains. The outer lens 1 is made entirely of transparent materials, and no patterns or leather grains are set on its inner and outer surfaces. The high and low beam module 2 includes a PCBA circuit board, an LED light source, and a professional optical structure 6 (such as a thick wall), wherein the LED light source is welded on the PCBA circuit board and faces the optical structure. An arc-shaped convex surface 7 is provided on the light incident surface of the optical structure 6, and a step 8 is provided on the edge of the optical structure 6 near the light transmission area of the two-color module bezel, and the two planes of the step 8 constitute a reflection surface.

The light-emitting principle of the car light is as follows: the LED light source of the high and low beam module 2 emits light after being energized, and most of the light passes forward through the optical structural member 6 to realize the high and low beam function; a small part of the light enters the light surface by the optical structural member The protrusions 7 are refracted to the step 8, which is reflected to the light-transmitting area of the two-color module bezel, and passes through the optical pattern 10 and the leather pattern 9 in sequence, forming a position light lighting effect as shown in Figure 5.
