ABSTRACT:
A ceiling mounted lighting fixture of the present invention accepts a PL-type fluorescent bulb. The lighting fixture includes a socket assembly which is recessed in a ceiling and a reflector mounted to the socket assembly. The socket assembly includes a base and a cover which cooperate to define a chamber having a bottom surface. A power supply for the PL lamp is made part of a circuit board. A receptacle on a lower surface of the bottom surface accepts the PL-bulb. The receptacle is accessible through the reflector. It includes a receptacle chamber sized and shaped to receive the bulb base, and at least two pin holes sized and shaped to receive the bulb pins. The pin holes extend through the receptacle and socket base bottom surface, so that when the bulb is inserted in the receptacle, the bulb pins will be in electrical contact with the circuit board.
