Vehicle lamp heat dissipation decoration ring

Abstract

The invention provides a vehicle lamp heat dissipation decoration ring. The ring comprises a heat conducting plastic base material and a pre-printed film, the pre-printed film is fixed to the surfaceof the heat conducting plastic base material through fitting and covering and comprises a transparent film and a printing coating layer, the printing coating layer is located between the transparent film and the heat conducting plastic base material. The vehicle lamp heat dissipation decoration ring is not likely to deform due to high temperature, the surface visual effect is good, the degree of freedom of modeling design is wider, the manufacturing processes can be reduced, and the cost is lowered.

Description

technical field [0001] The invention relates to the field of car lamp decorative rings, in particular to a car lamp heat dissipation decorative ring. Background technique [0002] Headlights are the eyes of the car, which are both safety parts and appearance parts. The decorative circle of the car light plays an important role in the shape of the car light. At present, the car lamp bezel is generally made of plastic material by injection molding, or the injection molded blank is subjected to surface treatment processes such as vacuum aluminum plating and surface spray painting to achieve different decorative effects. [0003] Due to the high internal temperature of the lamp, or the easy formation of focus under the sun, the local temperature of the decorative ring is too high. The heat-resistant temperature of the bezel depends on the plastic substrate itself. When the local temperature of the bezel is too high, it will cause the material to be deformed by heat. At this t...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a heat-dissipating decorative ring for car lamps, which solves the problems of deformation of the decorative ring caused by excessive local temperature of the decorative ring of car lights, and poor surface treatment effect caused by surface defects of heat-conducting plastics. At the same time, the design freedom of the surface shape of the bezel is wider, which can reduce the manufacturing process and reduce the cost
