Abstract
Abstract The assembly includes a number of readily replaceable low voltage light bulbs; for example, of the <5 watt 24 VAC type, spaced along a pair of electrical conductors carried by an insulated strip located in a housing with a removable transparent cover. The bulbs are releasably connected to the conductors in parallel by suitable electrical contacts, with or without supporting bulb brackets so that the conductors, strip and housing can be transversely severed between adjacent bulbs to shorten the assembly. Conversely, a number of assemblies can be connected in tandem to form an elongated lighting system. The cover may have edges which clip into recesses performed in the housing for ease in closing and opening the assembly. The housing may be aluminum and the cover may be polycarbonate plastic. The assembly is simple, inexpensive, adaptable to a variety of decorative uses and is durable.
