Abstract:
1. A retractable recessed emergency luminaire, which is actuated when power to the primary lighting source in a room is interrupted, comprising: a) a frame positioned flush with a wall or ceiling aperture and presenting an opening; b) an enclosure mounted to said frame and positioned inside the wall or ceiling for providing a protected housing; c) a panel having a center axis, said panel attached to said frame so that said panel may rotate about its center axis between a closed position and an open position; d) a light source mounted to one side of said panel such that when said panel is in the closed position the light source is completely enclosed within the enclosure and when said panel is in the open position the light source is exposed to illuminate at least a portion of said room; e) a motive means for rotating said panel from the closed position to the open position when power to the primary lighting source in said room is interrupted and for rotating said panel from the open position to the closed position when power to the primary lighting source in a room is restored, the motive means being continuously mechanically connected to the panel, and comprising: f) a control circuit electrically connected to said motive means and to said light source, said control circuit including: i) means for sensing when power to the primary light source has been interrupted and restored, ii) means for activating said motive means until said panel is in its open position and contemporaneously activating said light source when said power has been interrupted, and iii) means for activating said motive means until said panel is in its closed position and turning off said light source when power to the primary light source has been restored.
