Abstract
A light fixture including a housing formed by a pan having parallel side walls terminating in mounting phalanges formed with O-ring rungs and further including retainer rails which engage the opposite side of a flexible lens to hold the lens against an O-ring in the O-ring runs to maintain a moisture resistant seal.
Claims15
A moisture resistant fluorescent light fixture comprising:
- a channel shaped pan for mounting light tube sockets and formed with side walls spaced laterally apart to form therebetween a downwardly opening window and configured with respective parallel mounting flanges defining respective horizontal facing mounting surfaces, said flanges formed with respective longitudinal O-ring glands opening downwardly into said surfaces;
- said side walls further projecting downwardly on the laterally outer sides of the respective said mounting surfaces and configured with laterally inwardly projecting longitudinal mounting rails;
- a pair of end caps fastened to the opposite ends of said pan and formed with respective end cap mounting surfaces, said end caps further formed with C-shaped in plan O-ring glands projecting transversely and turning longitudinally to terminate in respective longitudinal gland segments aligned with the respective ends of the longitudinal O-ring glands;
- an endless O-ring received in said glands and projecting downwardly from the respective mounting surfaces;
- a lens configured to cover said window and formed along with lateral edges defining respective laterally outwardly opening grooves removably engaged with the respective said rails;
- and
- said lens further including an upwardly facing boarder defining lands configured to sealingly engage the respective longitudinal runs of said O-ring.

A moisture resistant fluorescent light fixture comprising:
- a housing body formed with downwardly projecting side and end walls, configured at their lower extremities with mounting forming downwardly facing side and end mounting surfaces, said flanges being formed with an endless O-ring gland having longitudinal and transverse runs and opening downwardly;
- an O-ring received in said gland;
- said housing further including opposite sides formed with retainer elements projecting downwardly below the side mounting surfaces and formed with respective inwardly turned mounting rails spaced horizontally below the plane of said side mounting surfaces;
- and
- a flexible lens including opposite extremities formed with respective longitudinal lands to engage the respective longitudinal runs of said O-ring and further configured along said opposite extremities with laterally outwardly opening mounting grooves for engaging respective said rails and so configured as to, when so engaged, sealingly engage said lands with the respective said longitudinal runs of said O-ring.
