ABSTRACT:
A housing frame preferably formable as a single integral unit and being capable of use as a primary structural portion of a housing suitable for multiple exit sign configurations, the several exit sign configurations of the invention being either intended for emergency or non-emergency operation and further being intended for use with different light sources and power sources. The housing frame of the invention includes structural features which allow mounting of any one of a variety of light sources and mounting of those components necessary for operation of the light sources within a single housing, which housing is of a size reduced in volume relative to most presently available signs. Structural features of the frame also include in at least certain embodiments a printed circuit board comprising a platform and having essentially all circuit components including light emitting diode light sources and a battery for operation of the light sources in an emergency mode mounted on said printed circuit board. The printed circuit board or platform is mounted immediately above a floor of the housing frame by a support structure comprising an irregular vertical wall extending upwardly from the floor of the housing frame. The frame and associated plates forming the housing of the invention are preferably formed from polymeric material of a thickness less than that of prior "plastic" housings, the strength and rigidity necessary to proper operation of the housing being provided by a functionally interrelated combination of structural elements which allows a substantial reduction in material used for formation of the housing.
