Abstract
Reflector lamps having vitreous, light transmissive reflectors and containing a source of visible and UV light radiation produce little or no UV radiation in the projected light beam by having a light reflecting coating on the exterior surface of the reflector and the reflector made of UV absorbing glass or having a UV absorbing coating disposed between the light reflecting coating and the exterior reflector surface. An anti-reflecting coating disposed on the interior, light-receiving surface of the reflector reduces UV emission still further.
