Abstract

An integral LED light fixture for installation in an incandescent light bulb socket includes a housing with a forwardly-extending portion and peripheral outer walls defining a recess, a rearwardly-extending socket base to be screwed into an incandescent light bulb socket, electrical components having an LED driver component, a driver cover and a printed circuit board having a set of LED bulbs and an orifice for receiving the central portion of the housing, which are nested into a compact set of electrical components, and a lens for covering the printed circuit board and being attached to the housing. The integral LED flight fixture cover can also be installed in a junction box. An AC version is also provided which lacks the driver component and the driver cover.
