Abstract
A lightweight emergency lighting system capable of arrangement into various subjective configurations is provided. A housing member supports a plurality of individual lighting elements mounted on a common semi-rigid bus bar. The upper configuration of the housing members is capable of a directional transmission of light towards a predetermined field angle, while the lower configuration is adaptable for mounting the lighting elements. The upper housing member can have an interior surface of a prismatic configuration to provide a refraction and reflection of light in combination with the exterior surface. The lighting elements, such as L.E.D.'s, can be excited through a pulsing circuit to maximize the light output while conserving power from an auxiliary battery source.
