ABSTRACT:
In an exit sign, a plurality of rugged low voltage incandescent lamps are mounted on a printed circuit board to provide proper illumination. The lamps are positioned to provide indirect illumination to the "EXIT" stencilling of the exit sign. The exit sign can be adapted for use with both low voltage alternating current and low voltage emergency direct current. Because the lamps are driven at low voltage and are resistant to failure due to vibration, etc., they can be expected to attain a long life in service.
