Abstract
Abstract A fluorescent lamp housing for fluorescent tubes comprising an elongate body with a curved central back and curved legs arranged to fit closely around a fluorescent tube. A wiring chamber is isolated from a lamp chamber by an insert strip; electrical sockets are positioned at opposite ends of the lamp chamber and are held in the housing by positioning clips and end plates. The end plates are attached by screws to the clips and are attached to tubular extensions of the wiring chamber. The tubular extensions have ends press-fitted into the wiring chamber and serve as wire guides and as journals that are clamped in mounting brackets. An insertion and removal aid is preferably provided to facilitate insertion and removal of the lamp with respect to the closely fitting housing.

Claim 1
Independent Claim
230 words
A housing for a fluorescent tube comprising a casing having a curved back, curved apart, diverging legs extending from the curved back; converging edges at the ends of the legs remote from the curved back; means forming an electrical chamber and a lamp chamber separated from said electrical chamber in the casing by a divider strip inserted into opposing grooves in the legs; socket means in the lamp chamber to receive the contact pins of a fluorescent tube; and mounting means for mounting the casing to a support structure, said mounting means including tubular means extending axially from opposite ends of the electrical chamber; and clamp means adapted to be fixed to said support structure, said clamp means having a bracket with a back and spaced apart legs extending from the bracket and straddling each tubular means; a bolt extending through one leg and threaded into the other leg whereby turning of the bolt will clamp the legs to the tubular means; and means to attach the bracket to a display case or the like, said means comprising an opening through the back for inserting of a screw therethrough to be threaded into a display case, and a hole through one leg for insertion of a screw therethrough to be threaded into a display case and a larger aligned access hole through the other leg to provide for screwdriver insertion.
