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.
