Abstract
The present invention is an improved emergency luminaire, which is recess-mounted flush within a wall or ceiling aperture, having an enclosure, a panel, a light source, a means for rotating the panel from the closed position to the open position and a means for rotating the panel from the open position to the closed position. The means for rotating the panel from the closed position to the open position includes a single-directional motor. Upon electrical power failure to the primary lighting source in the room, the single-directional drive motor is activated causing the panel to rotate 180 degrees from a closed position to an open position, thereby exposing the light source to view. Substantially simultaneously with the panel opening, power stored in batteries are connected to the light source, causing it to illuminate. When the primary electrical power is restored, the light source is extinguished and the single-directional drive motor is activated returning the panel to its closed position.
