Zusammenfassung:	An elevator cab in which emergency lighting is concealed until it is required to be utilized. When the normal electrical power supply to the cab fails, the emergency lighting is automatically pivoted from a concealed position behind an inconspicuous wall plate to an exposed position which projects the lens of the emergency lighting fixture into the cab through the opening previously closed by the inconspicuous wall plate. In the exposed position, the emergency lighting is energized by an emergency power supply, with the emergency power supply also automatically becoming available when the normal power supply fails. In a preferred embodiment, the emergency lighting is located in the return, directly above the car station, and below the transom.
