Abstract: 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.

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. 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 whereby to operate the LED modules at a lower temperature than the critical thermal temperature Tc of the LED modules whereby to achieve lifespan, photometric and colorometric rating of the LED modules.

Abstract: A retrofit LED lamp assembly for the replacement of light bulbs in optical lamps mounted elevated on support posts is described. The optical lamps have a lamp housing with a reflector secured therein and supporting a light bulb. A glass shade projects the light. The retrofit LED lamp assembly has a support member on which light emitting diodes (LED's) are electrically insulatingly supported to replace the light bulb. An adjustable connection assembly is provided to secure the support member to the reflector. The support member is configured to position the LED's at a predetermined angle and orientation relative to configured reflective surface segments of the reflector whereby to produce a desired oriented photometric light distribution pattern. A heat sink is securable in contact with the support member to dissipate heat. A clear tempered glass lens replaces the glass shade.
