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.
Claims3
A reflector lamp comprising a vitreous, light-transmissive reflector having a visible light-reflecting coating on its exterior surface and containing a source of visible and UV light radiation within, wherein said emitted UV radiation is absorbed by (i) said reflector, (ii) said light-reflecting coating, (iii) a UV absorbing coating disposed between said light-reflecting coating and said exterior reflector surface, or combination thereof.
