Abstract:
A fixture utilizing glass tubing containing a medium that luminesces when electrically excited including:a first member comprised of laterally spaced apart longitudinally extending side walls and a bottom wall defining a channel for being fixedly mounted, the channel having an open side presented in one direction and the side walls having rims, respectively, extending along the channel,a second member comprised of a longitudinally extending support wall having one side for mounting the glass tubing and an opposite side from which laterally spaced apart longitudinally extending side walls project to define with said support wall a channel having an open side and a space between the side walls,elements on the side walls of the first member and on the side walls of the second member cooperating to interlock said first and second members such that said open side of said second member is presented in a direction opposite of said one direction so the open sides of the first and second members face each other,laterally spaced apart interlock elements formed integrally with and on said opposite side of the support wall of the second member and extending longitudinally thereof and having a defined cross-sectional configuration,a cover member composed of light transmitting material for covering a glass tubing mounted to said opposite of said support wall of the second member, said cover member having longitudinally extending and laterally spaced apart side walls and marginal edges on which there are interlock elements having a cross-sectional configuration complementing said defined cross-sectional to provide for mutual engagement of the interlock elements on the second member and cover member to couple the last named members together, anda power supply assembly operative to apply a potential to said tubing to excite said medium, the power supply assembly being disposed in said space between the side walls of said second member and including elements on the last named side walls on which said assembly is supported.
