Abstract: An emergency lighting unit comprises a housing which contains the lighting unit circuitry. The housing includes a wall which defines at least one substantially circular opening therein. Extending partially through this opening is a substantially spherical lighting head containing a light source, such as a halogen lamp. The lighting head is rotatable by hand to any desired rotation to vary the field of illumination.

Abstract: Internally illuminated emergency signs are typically placed in elevated locations which are awkward for electricians to reach, yet must be securely mounted. It is therefore difficult and time-consuming to make wiring connections after the mounting operation is completed. In order to facilitate both quick and easy wiring of the sign, and secure mounting thereof, an improved canopy features a projecting bracket which slips into a slot in a side or top of the sign housing, and engages over horizontally extending screws. Rapid, yet secure mounting of the sign is achieved by cantilevering the sign on the bracket, if side mounting is used, or by use of a locking pin, if top mounting is used. The locking pin keeps the screws from sliding laterally with respect to the bracket.

Abstract: In an exit sign, a cover member for an emergency exit sign has a pair of hook members on its bottom wall and a pair of resilient spring finger members on its top wall. The hook members are dimensionally sized and appropriately positioned to engage catch members on an exit sign housing while the spring finger members resiliently snap fit within spaced apart apertures in the top wall of the exit sign housing thereby retaining the cover member in its closed position. A pair of flexible straps secure the cover member to the exit sign housing to keep them in assembly when the cover member is in its open position.

Abstract: An emergency lighting fixture comprises a housing which contains the lighting head with a light source such as a halogen lamp. The housing is positionable on its backplate in at least four different positions by use of mating slots and indexing members. The indexing members are mounted on extension members cantilevered from edges of the backplate. At least two screws are threadingly received in the extension members and engage the housing adjacent the slots to hold the housing and backplate in assembly.
