Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of headlamp production, in particular to a structure in which double thick walls of a headlamp are integrated into a single thick wall. Background Art
[0002] With the wide application of LED technology in the field of headlamps, thick wall structures are increasingly frequently used in headlamp designs. The thick wall is installed in front of the LED light source inside the lamp housing. In order to achieve good visual effects and cool shapes, thick wall structures are usually used in headlamps for shaping. The thick wall structure adds a crystal-clear appearance effect to the headlamp shape and provides more beautiful visual impacts to the headlamp. The design of the thick wall part is crucial for improving the light-emitting effect of vehicle tail lamps. For headlamps with a single thick wall structure, the light emission is uneven and there are problems with poor lighting effects. For the double thick wall headlamp design adopted in the prior art, although the problem of uneven light emission is improved, the double thick walls are of a separated structure. Since a set of molds cannot be used for production, facing the relatively high mold development costs during manufacturing, the production costs are also relatively high. Affected by the overall industry environment, the pressure on automotive costs is increasing. Therefore, automotive lamps also need to transform towards simpler structures and optimal costs. Content of the Utility Model
[0003] Aiming at the problems and actual requirements of the prior art, the utility model provides a structure in which double thick walls of a headlamp are integrated into a single thick wall to solve the problems.
[0004] The technical solution adopted by the utility model is as follows:
[0005] A structure in which double thick walls of a headlamp are integrated into a single thick wall, including an LED module and a thick wall, characterized in that: the LED module is provided with LED lamp beads and is fixed on the thick wall; the thick wall is provided with a light-concentrating surface and an outer surface, and by opening a structural groove with a through-strip, an optical correction surface I and an optical correction surface II are formed, and the sequentially arranged light-concentrating surface, optical correction surface I, optical correction surface II and outer surface are integrated on the integrated thick wall, constituting a structure in which double thick walls are integrated into a single thick wall.
[0006] The light-concentrating surface of the thick wall is set as a convex surface, and the optical correction surface I, the optical correction surface II and the outer surface are all provided with patterns.
[0007] The patterns are: uniformly distributed lines in the shape of corn kernels, or uniformly convex strip-shaped lines.
[0008] The structure of the double thick-walled integrated into a single thick-walled of the headlamp of the present utility model is scientifically novel in design, reasonable and compact in structure. The light emission is modulated by the light condensing surface, the optical correction surface and the outer surface, with good lighting effect, better reflecting the uniformity of the headlamp, and better reflecting the texture of the whole vehicle. It meets the requirements of the vehicle manufacturer for the lighting uniformity and appearance of the lamp, with safe and reliable functions, can save the development cost of the whole lamp, and saves multiple screws and the installation process of workers, improving the production efficiency, and playing a great role in reducing the cost of a single lamp.

[0014] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described below are only used to explain the present utility model. In these descriptions, the key words that need to be noted include "thick wall", "light condensing surface", "optical correction surface", "pattern", "convex surface", "corn convex grain shape", "convex strip", etc. These are only for the convenience of describing the present utility model and simplifying the description, and therefore cannot be understood as a limitation to the present utility model.
[0015] As Figure 1 and Figure 2 shown, the structure of the double thick-walled integrated into a single thick-walled of the headlamp of the present utility model is used for the vehicle brake lamp in this embodiment, including an LED module 1 and a thick wall 2. The LED module 1 is provided with LED lamp beads, which are fixed on the thick wall 2 made of transparent material by thermal riveting. Refer to Figure 3As shown, the thick wall 2 is provided with a light-concentrating surface a and an outer surface d, and forms an optical correction surface b and an optical correction surface c by opening a structural groove for a through-strip, and the light-concentrating surface a, the optical correction surface b, the optical correction surface c and the outer surface d arranged in sequence are integrated on the integrated thick wall 2, constituting a structure in which a double thick wall is integrated into a single thick wall. The light-concentrating surface a of the thick wall 2 is provided with a convex surface, and the optical correction surface b, the optical correction surface c and the outer surface d all have patterns to ensure uniform lighting. The patterns are, for example, the evenly distributed lines similar to corn convex grains as shown in the outer surface d in the figure, or, the evenly distributed convex strip-shaped lines as shown in the outer surface b in the figure, or other evenly arranged lines. These evenly arranged lines modulate the uniformity of light emission.
[0016] When the present utility model is in use, the LED lights on the LED module 1 project the scattered incident light onto the light-concentrating surface a of the thick wall 2, modulate them into a flat projection through the convex lens effect, enter the optical correction surface b with patterns, and then enter the optical correction surface c with patterns, and finally emit light evenly from the outer surface d with patterns.
[0017] The above is only one implementation manner of the present utility model. For those skilled in the art, the present utility model may also have various other implementation manners with changes and modifications, which will not be elaborated here one by one. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model are all included within the protection scope required by the present utility model.
