ABSTRACT:
A planar fluorescent lamp lamp includes a first transparent cover bonded atop a metal body with a serpentine channel therein. The lamp body is coated with an insulative coating and the glass solder bead bonds the cover to the lamp at its perimeter and along the ridges defining the serpentine channel. An alternative embodiment of the lamp includes a second transparent cover bonded above the first transparent cover enabling the fluorescent material to be contained in a second enclosure, isolated from the source of light energy. A second alternative embodiment conceals the electrodes of the lamp beneath the lamp body and provides plasma slots to allow the concealed electrodes to energize the lamp. Another alternative embodiment utilizes a conductive transparent coating on the lamp cover to allow the lamp cover to supplement the lamp body as a cold cathode.
