Emergency lighting apparatus
First Claim
1. Emergency lighting apparatus for attachment to a building structure and responsive to an operating condition of a utility line comprising:
- housing support means for securing a housing to a structure;
housing means coupled to the housing support means for adjustably supporting a lamp head and encasing a lamp power supply and lamp actuator circuitry;
lamp head means for supplying a an adjustable lighted beam in response to sensing a loss of utility voltage, the lamp head means at least partially enclosed by and coupled to the housing means;
power supply means for powering the lamp head means in event of power outage independently of a utility voltage, the power supply means disposed within the housing means and electrically coupled to the lamp head means; and
circuit means for engaging the power supply means to actuate the lamp head means in response to an indication of loss of power, the circuit means disposed within the housing means; and
in whichthe housing means comprises tube means for supporting the power supply means and the circuit means, and envelope means disposed about the tube means for at least partially enclosing the tube means and supporting lamp head means adjacent opposing ends of the housing means, the envelope means providing a decorative appearance to the lighting fixture;
whereby an emergency lighting fixture is provided which retains its power supply and circuitry internal to its housing means which also at least partly encloses the lamp head means, supports the weight of the housing means by the housing support means, and allows light beam positioning.

Abstract
An emergency lighting fixture has a capped circular and longitudinally slotted tube containing a power supply and charging electronics. Cylindrical outer envelopes rotatably enclosing the tube each have pivotally mounted lamp shells at opposing ends. A spider plate attachable canopy having integrally molded apertured inner lugs has an outer integrally molded arm supported overhanging portion, the arm being of substantial cross section for supporting the tube weight centrally supporting the lighting fixture. The tube has a longitudinal support slot receiving a rectangular support piece terminating from the canopy arm. End caps enclosing tube ends each have a circumferential groove for receiving guide nubs are disposed in spaced apart relationship on the inner circumference of the envelopes. The envelopes have oblique truncated surfaces allowing beam positioning without envelope interference. Installation is achieved by affixing the spider to an outlet box, joining the wires of the outlet box to those from the canopy, and affixing the canopy to the spider plate. The support portion of the canopy is slid into the tube slot and tube, the envelopes are fitted over the tube and polarized electrical connectors are joined. Beam adjustment is effected by envelope rotation and shell pivoting, without significantly changing the overall cylindrical appearance of the fixture.

8. Emergency lightling apparatus comprising:
-
canopy means for securing a housing to an electrical outlet box; the canopy means having a cantilever arm for supporting a housing; a housing supporting emergency lighting apparatus for actuating a light beam in response to an indication of a loss of utility voltage, the housing being coupled to the canopy means for retaining battery means and and electronics for powering lamp means and supporting lamp head means; the housing comprising a cylindrical tube and two cylindrical envelopes disposed in juxtaposition on the tube adjacent opposite sides of the cantilever arm of the canopy means;
the envelopes remotely supporting lamp heads, the envelopes substantially enclosing the tube and rotatable about the tube for adjusting the positioning of the lamp heads axially about the housing, the envelopes providing a decorative appearance to the lighting fixture;lamp heads pivotally coupled at opposing ends of the envelopes remote from the cantilevered protrusion of the canopy for providing an adjustable light beam; battery means for powering the lamp head means in the event of power outage, the battery means disposed within the tube; and means for engaging the battery means and actuating the lamp head means in response to an indication of loss of power; whereby an emergency lighting fixture is provided having a uniform outer appearance irrespective of beam positioning, yet retains the battery and electronics internal to the cylinder, supports the weight of the lighting fixture by the canopy and allows adjustment of lighting positioning, yet may be simple to install as a result of preinstallation of components within the tube. - View Dependent Claims (9, 10, 11, 12, 13, 14)
