An elevator system including an elevator car mounted for movement in a building to serve the floors therein. The elevator system includes control apparatus for selecting the service direction in which the elevator car will proceed from a floor it is serving. A display having an array of electrically energizable elements visually indicates the selected up or down service direction by sequentially energizing the elements to provide a predetermined pattern which moves upwardly, or downwardly, through the array, or which causes a predetermined pattern to lengthen in the upward, or downward direction.

Elevator system

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 certain 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 providing 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.
