Patent ID: 8882297

Claim:
An LED-based lamp assembly for use with a light fixture having a socket portion, the lamp assembly comprising: a driver assembly having a base portion rotatably engageable with the socket portion to make a first electrical contact with the light fixture, the driver assembly having an electrically conductive tip portion coupled to the base portion, the tip portion being engageable with the socket portion to make a second electrical contact with the light fixture; and a lamp housing assembly connected to the driver assembly, the LED lamp assembly having a lamp housing connected to the driver assembly, the lamp housing having electrical contacts operatively connected to the driver assembly, the lamp housing assembly having a heat sink coupled to the lamp housing, the heat sink having a support portion and a plurality of fins coupled to the support portion and configured to form air columns between adjacent fins, the support portion having a plurality of first apertures therethrough in communication with the air columns, the lamp housing assembly having at least one LED circuitry layer having a plurality of second apertures therethrough and at least one LED light thereon, the LED circuitry layer being connected to the support portion of the heat sink, the second apertures being in alignment with the plurality of first apertures and in alignment with the air columns, the lamp housing assembly having a fan positioned adjacent to the heat sink with the heat sink positioned between the fan and the LED circuitry layer, the fan being positioned to move air through the air columns in the heat sink and through the plurality of first and second apertures to move a flow of heated air away from the LED circuitry layer, the lamp housing assembly being rotatable relative to the light fixture to adjust the angular position of the LED circuitry layer while maintaining the first and second electrical contacts between the driver assembly and the socket portion.
