46,636 ELEVATOR SYSTEM ABSTRACT OF THE DISCLOSURE An elevator system including an elevator car mounted for movement in a building to serve the floors therein. The elevator car includes a car call station with a continuously energized light source associated with cer- tain display functions. An emergency source of electrical potential is applied to this light source when the normal source of electrical potential fails, and this light source provides emergency lighting for the elevator car by pro- viding light transmitting portions on the car call station panel and/or by operating electro-optic light valves located on the car call entry station to their light transmitting condition. The electro-optic light valves used for the emergency lighting function may be those utilized for other display purposes during normal operation of the car call entry station, and/or light valves which are only operated during use of the emergency source of electrical potential.
