A compact and cost-efficient lamp assembly includes cold-cathode fluorescent lamps in a variety of edge-lit display sign applications specifically, in edge-lit emergency lighting signs. The lamp assembly includes in one self-contained module a lower housing unit and an upper housing unit shaped to cover the lower housing unit. The lower housing unit is divided into a lower frame and an upper frame disposed on top of the lower frame. The upper frame has at least two inverters disposed within. The lower frame is a parabolic shape reflector frame supporting at least two cathode lamps in line with the two inverters, each of which is connected to each lamp for providing high voltage to power up the lamps. Additionally, an edge-lit panel having a front and back side is disclosed in the present invention. The backside includes a semi-transparent frosted surface with a white opaque lamination glued on the frosted surface. A legend is printed on the front side using a first white layer and a colored second layer of semi-transparent materials. So, when the light passes through the first layer it is split in such a manner that part of the light is reflected back into the panel and the other part of the light illuminates the second colored layer.

Cold-cathode fluorescent lamp assembly for lighting applications

The present invention provides an easily assemble swivel mount for supporting a fixture from a support. This swivel mount is of a design such that no tool or special device is needed to either initially position the fixture at a desired location or to change or re-position the fixture should such be desired. A continuous wire passageway is provided through the swivel mount so that no obstacles need be avoided thereby eliminating the possibility that a wire may become kinked within the swivel mount. Such continuous passageway also makes for easy wire insertion through the swivel mount.
