<p>A vehicle headlamp having a light shield that does not outgas under normal lamp operation is disclosed. The vehicle headlamp uses a light shield with an 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 t o leave a film on the other lamp elements.</p> |
