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.

Emergency lighting fixture

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.

Sign having a curved face

An illuminated exit sign having at least one chevron-shaped opening on its outer surface and a replaceable directional arrow cover that is substantially similar in shape to the opening and removable from the opening in order to selectively indicate an exit direction. A shoulder which is formed in the cover is adapted to abut with a shoulder formed at the opening. At least two snap tabs located on opposite sides of the arrow cover fit securely within corresponding notches disposed in the shoulder formed at the opening. The opposing configuration of the shoulders and the corresponding configuration of the snap tabs and notches facilitate the removal and replacement of the arrow by a single, quick snapping action which secures the cover in a snug, flush fit.

An emergency lighting fixture, for plug-in installation in a wall connector mounted protruding from a fixed wall plate, has a back plate secured to its wall-engaging face. The back plate and the wall plate are provided with interfitting flanges and a pivoted latch secures the plates together in facing juxtaposed engagement. A mating multi-prong plug and socket connects A.C. line power from the wall connector to internal circuitry in the lighting fixture for lighting a lamp, for charging a rechargeable internal battery and for operating a transfer circuit to deliver battery power in the event of line power failure. The conductor from one terminal of the battery is connected to said circuitry by two prong-and-socket pairs, in the multi-prong plug and socket, which are connected by a permanent jumper conductor in the wall connector, affording battery isolation in the lighting fixture until its plug-in installation in the wall connector is completed.
