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.
A sealed optical street lamp having a lamp housing fitted with a lens, a reflector supported in said housing, said reflector having configured reflective surface segments, an LED light source assembly mounted in said reflector and adjacent said lens, said LED light source assembly having a thermally conductive support member on which light emitting diodes (LED's) are electrically insulatingly supported, adjustable connection means to secure said support member to said reflector and position said support member and said LED's at a selected one of two or more predetermined positions relative to said reflective surface segments of said reflector, said adjustable connection means being a support rod secured at one end to said support member and at an opposed end to a reflector connector secured to said reflector, and means to adjust the axial displacement of said support rod exteriorly of said reflection, said support rod having at least an adjustably engageable portion extending through said reflector connector and a lock member to arrest the position if said adjustably engageable portion relative to said reflector connector, said support member being configured to position said LED's at a predetermined angle and orientation relative to said configured reflective surface segments of said reflector whereby to produce a desired oriented photometric light distribution pattern, and heat dissipation means in contact with said support member and adapted to dissipate heat from said support member to said reflector and said lamp housing to provide an efficient temperature environment for said LED's.
A retrofit LED lamp assembly for the replacement of light bulbs in optical lamps mounted elevated on support posts, said optical lamps having a lamp housing with a reflector secured therein and supporting a light bulb and a glass shade for the projection of light, said retrofit LED lamp assembly comprising a support member on which light emitting diodes (LED's) are electrically insulatingly supported to replace said light bulb, connection means to secure said support member to said reflector, said support member being configured to position said LED's at a predetermined angle and orientation relative to configured reflective surface segments of said reflector whereby to produce a desired oriented photometric light distribution pattern and a heat sink securable in contact with said support member to dissipate heat said connection means being a reflector connector adapted for mounting in an opening of the reflector created after the removal of a lamp socket connector of said lamp, said connection means being an adjustable connection means having an adjustable support rod adjustably connected to said reflector connector, said adjustable support rod has an engageable portion extending through said reflector connector and a threaded lock member to arrest the position of said threaded portion relative to said reflector connector.
A sealed optical street lamp having a lamp housing fitted with a lens, a reflector supported in said housing, said reflector having configured reflective surface segments, an LED light source assembly mounted in said reflector and adjacent said lens, said LED light source assembly having a thermally conductive support member on which light emitting diodes (LED's) are electrically insulatingly supported, connection means to secure said support member to said reflector, said support member being configured to position said LED's at a predetermined angle and orientation relative to said configured reflective surface segments of said reflector whereby to produce a desired oriented photometric light distribution pattern, and heat dissipation means in contact with said support member and adapted to dissipate heat from said support member to said reflector and said lamp housing to provide an efficient temperature environment for said LED's, said heat dissipation means being comprised of a finned heat sink secured in direct contact with said support member, said support member being formed by a flat heat conductive metal plate shaped to define a flat connecting end wall section and opposed spaced-apart flat branch sections, each branch section having a straight inner section extending transverse to said end wall section and a straight outwardly flared outer section, said finned heat sink having a rectangular heat spreading core section having opposed heat conductive flat walls, said core section being secured between said straight inner sections of said spaced-apart branch sections with said opposed heat conductive flat wall in flush contact with an inner surface of a respective one of said straight inner sections, said finned heat sink having wing sections extending outwardly of said core section and laterally of said opposed heat conductive side walls.
