Title: Incandescent bar display module

Abstract: A bar-type display utilizing incandescent lamps stacked in a linear array in a metallic lamp block preferably of aluminum shaped to form a parabolic reflector configuration along its length and a tongue and groove configuration for attachment to an insulating connector block. Fins are provided on each side of the block for heat dissipation and grooves are formed transversely of the block through the parabolic reflector configuration at intervals into which barrier plates are inserted to sectionalize the block into separate reflectors for each lamp. To disperse the radiated and reflected light, a plastic diffuser is placed across the top of the reflector configuration, which may be colored to color the transmitted light, and to provide anti-reflective qualities for non-glare viewing. The insulator connecting block is molded to the lamp block and the lamp pins are arranged so that alternate lamps may be powered by separate power supplies for redundancy purposes.
