Abstract
The vehicle headlamp uses a light shield with a interior surface with a rough, black ceramic coating. The ceramic surface absorbs almost all the visible light shone on it. The surface is highly resistant to the heat generated by the light absorption, and the roughness breaks up visible light images in any small amount of reflected light. The ceramic material does not outgas or deteriorate so as to leave a film on the other lamp elements.
