Elevator light curtain is elevator door safety protection device used to protect the safety of passengers. On both sides of the elevator cabin door, two elevator photocell bars are installed with each bar about 2meters long.
It consists of infrared transmitters and receivers installed on both sides of the elevator door and specialized flexible cables. There are multiple infrared emission tubes inside the infrared emitter. Under the control of the microprocessor, the emission and reception tubes are sequentially opened to continuously scan the elevator door area from top to bottom, forming a dense infrared protection light curtain.
When any beam of light is blocked, the control system will immediately output a signal to open the door, and the it will stop closing and reverse opening until the obstruction leaves the warning area before the elevator door can be closed normally.
