Abstract
An emergency light unit (arranged in an elevator cage) of an elevator installation can be activated. A light sensor unit and a lighting unit are arranged in the elevator cage. The emergency light unit is activated by an elevator control unit in dependence on at least one light intensity value detected by the light sensor unit when the elevator cage door is closed and transmitted to the control unit.
Claims16
A method for activating an elevator emergency light in an elevator cage, the method comprising:
- using a light sensor to generate at least one light intensity value while a door of the elevator cage is closed, the light sensor being arranged in the elevator cage;
- and
- activating, using a control unit, a light unit based on the at least one light intensity value, the light unit being arranged in the elevator cage.
An elevator operating unit comprising:
- a light sensor in an elevator cage, the elevator cage comprising a door;
- and
- a processor-based control unit, the control unit being programmed to,
- receive a light intensity value from the light sensor, the light intensity value having been generated by the light sensor while the door was closed, and
- activate an emergency light unit in the elevator cage based on the received light intensity value.
An elevator installation, comprising:
- an elevator cage disposed in a shaft, the elevator cage comprising a door;
- a processor-based control unit;
- a light sensor disposed in the elevator cage;
- a light disposed in the elevator cage;
- and
- an emergency light disposed in the elevator cage, the control unit being configured to,
- receive a light intensity value from the light sensor, the light intensity value having been generated by the light sensor while the door was closed, and
- activate the emergency light based on the received light intensity value.
One or more computer-readable storage media having encoded thereon instructions that, when executed by a processor, cause the processor to perform a method, the method comprising:
- receiving a light intensity value from a light sensor disposed in an elevator cage, the light intensity value having been generated by the light sensor while a door of the cage was closed;
- and
- activating an emergency light unit in the elevator cage based on the received light intensity value.
