Abstract
Abstract A low voltage lighting fixture designed for outdoor use and constructed mainly of polyvinyl chloride. The fixture includes a cylindrical housing made entirely of white high density polyvinyl chloride, a 12 volt lamp, a lens, a pair of rubber O-rings, a lens, a lens retaining ring made of polyvinyl chloride, a circular rear base plate, and a power line passing through a hole in the base plate for energizing said lamp. The lamp is sealed within the housing by the two O-rings, the lens and the retaining ring.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
198 words
An electric lighting fixture for outdoor use comprising: a cylindrical housing made entirely of polyvinyl chloride and having concentric inner and outer walls, said housing having an annular ring projecting from its inner wall, a first flexible O-ring having an outer diameter slightly less than the diameter of the inner wall of said housing positioned against the surface of said ring, a low voltage electric lamp having an outer diameter slightly less than the diameter of the inner wall of said housing, the lower edge of said lamp being positioned against said first O-ring, a second O-ring identical to the first O-ring positioned against the upper edge of said lamp, a circular lens having an outer diameter slightly less than the diameter of the inner wall of said housing positioned against said second O-ring, and a lens retaining ring made entirely of polyvinyl chloride with an outer diameter slightly less than the diameter of the inner wall of said housing firmly pressed against the outer surface of said lens so as to cause the two flexible O-rings to seal against the inner wall of said housing and said ring being secured in position by joinder to said housing.
