Abstract:
1. An indoor sealed optical luminaire comprising a heat conductive support forming a head of said luminaire, said heat conductive support having a reflector secured in a lower surface portion thereof, a clear, flat lens sealingly secured about a circumferential side wall of said reflector, a heat dissipating LED support member secured to said lower surface portion of said heat conductive support and spaced rearwardly of said lens, a pair of high power LED modules secured to said LED support member and disposed in spaced relationship at a predetermined angle and orientation relative to an inner reflective surface of said circumferential side wall of said reflector whereby to produce a desired oriented photometric light distribution pattern on a plane thereunder to be illuminated, said heat dissipating LED support member comprising a heat conductive support block transferring heat generated by said LED of said modules directly into said heat conductive support for dissipation in the ambient surrounding air to operate the LED modules at a lower temperature than the critical thermal temperature T c of said LED modules specified by manufacturer specification to achieve lifespan, photometric and chronometric rating of said LED modules while generating required lumens in conformity with photometric requirements for said plane to be illuminated.
