ABSTRACT:
An outdoor lighting fixture is disclosed for a circular fluorescent lamp. A first and second embodiments are disclosed for mounting in an upright position on a post or wall and a third and fourth embodiments are disclosed for mounting in a downward suspended position from a light socket. In the first and second embodiments, the fixture includes a base which opens upwardly in a generally circular, horizontal lip. A retainer plate envelops the lip of the base forming a weather resistant joint. The plate supports a circular fluorescent lamp in a horizontal orientation and a cylindrical, transparent shield envelops the retainer plate forming a weather resistant joint. In this manner, a circular fluorescent lamp can be operated in outdoor adverse weather environments. The third and fourth embodiments include a housing having a hollow cylindrical upper neck, a lower body and a downwardly depending shade portion which terminates in a circular skirt portion with a lens. The third embodiment includes an annular seal, compressively mounted between the lower flat surface of a first socket and the upper flat surface of a second socket, the seal mating with the inner surface of the neck of the housing. In the fourth embodiment, the body of the housing contains an electrical choke ballast. An encapsulating medium having good heat conducting properties is formed in the upper portion of the body of the housing enveloping the electrical choke ballast, to conduct heat from the ballast to the housing.
