Display case lighting system

A display case for jewelry or the like, having glazed front and top windows into a display space typically having a lockable mirrored sliding door back wall and a fabric-covered floor pad above an obscured storage space, has a shell construction mounted in the case so that it extends from end to end of the case in the upper front corner. The shell construction includes two opposed channels in which reflector panels mounting lamp holders for a requisite number of single base compact fluorescent lamps are slidingly received so as to form with the shell construction the hypotenuse of a triangular space serving as a raceway for the wiring of the lamp holders. At one end the collected wiring is directed down through a groove or raceway formed in or on one of the endwalls of the case, and into the obscured storage or base region of the case. Here, the wiring connects with a ballast assembly for the lamps. The ballast assembly, in turn, is provided with a power line emerging to the exterior with a plug for plugging to an electrical receptacle, or for plugging into a unit of another case for instances where several display cases are to be ganged together and electricity fed through the coupled electrical systems of two or more of them to reach the lighting systems of cases which are located remote from an electrical outlet.
