LED lamp assembly for sealed optical luminaires

摘要

A sealed optical street luminaire having a luminaire housing fitted with a clear, flat lens and provided with an LED light source assembly mounted in the housing. The light source assembly has a heat dissipating LED support member secured to a heat conductive adapter for securement in the luminaire housing. A reflector is secured in the luminaire housing behind the lens which is sealingly positioned about the reflector. The LED support member supports LED modules at a predetermined angle and orientation relative to an inner reflective surface of the circumferential wall of the reflector. The heat dissipating LED support member and the heat conductive adapter dissipate heat through the luminaire housing.

1. A sealed optical street luminaire having a luminaire housing fitted with a clear, flat lens, an LED light source assembly mounted in said housing, said LED light source assembly having a heat dissipating LED support member, a heat conductive support for securement in said luminaire housing with at least portions thereof in contact with at least a heat conductive portion of said luminaire housing, a reflector is secured in said luminaire housing behind said lens, a seal secured about a circumferential side wall of said reflector and disposed for sealing engagement with said lens, said LED support member having an LED support outer surface for securement of one or more high power LED modules 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 to be illuminated, said heat dissipating LED support member comprising a support block transferring heat generated by said LED modules directly into said heat conductive support for dissipation through said luminaire housing and having a heat dissipating capacity to operate the LED modules at a lower temperature than the critical thermal temperature Tc of said LED modules specified by manufacturer specification to achieve lifespan, photometric and colorometric rating of said LED modules while generating required lumens in conformity with photometric requirements for said plane to be illuminated.
