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.
