Abstract
An emergency lighting fixture includes a door and light source disposed on the door. The door rotates 360 degrees in one direction. A slip clutch assembly permits manual rotation of the door when obstructed by a motor or to remain in the same position when obstructed during rotation by the motor. A capacitor stores energy to close the door. A pressure locking assembly includes a bearing ball biased into engagement with an alignment hole by a spring in response to the door being rotated near a predetermined position. A conductive clip maintains electrical contact with a conductive portion of a hinge as the door rotates. The conductive clip is connected to a power source, and the light source is connected to the conductive portion of the hinge, thereby providing power to the light source after the door has stopped in a pre-determined position or during rotation of the door. The fixture may be used in non-emergency lighting applications.
