ABSTRACT:
A reflector lamp having a lens of vitreous material fused to a reflector body of vitreous material. An inner reflector surface of the reflector body includes a reflective coating having a first coating portion extending from the rim of the reflector body and a second coating portion extending from a location spaced from the rim towards a basal end of the reflector body. The second coating portion is a layer of heat-treated silver having a uniform, whitish non-metallic appearance and being diffusely reflective. The first coating portion is a layer of material other than silver, such as aluminum, having a higher resistance to damage by high heat in the rim area during fusing of the lens to the reflector body.
