Automotive Lamp Coating

Attractive designs with intense brightness are the demanding trend for automobile lamps. The design method is to apply a very bright metal aluminum layer on the surface of the lightweight plastic to form a mirror like finish on the surface. The mirror reflection effect of the parabolic curved back surface is matched with the front transparent lamp shell pattern, and concentrating the light source focal length of the paraboloid to form a parallel beam, sculptured light source.

The market demand for automobile lamps has been changing from the traditional halogen lamp to the LED lamp. Due to the intensity and precise focal point requirements of the LED lamp to produce the desired appearance, improved mirror finish coating are required. DAHYOUNG has accumulated process technology through research and development to meet these requirement so the LED lamps can be perfectly displayed as desired.
