Lights out in the office corridor after work.

With the development of science and technology, the lighting equipment in the corridor is voice-activated lighting. In the corridor where people walk, because of the sound, the corridor lights will light up automatically and go out automatically after people leave. Now the corridor lights are replaced by LED cold light source voice control lights, which are more energy-saving and electricity-saving than the previous lights. Therefore, it is no longer necessary to manually control the service time of the unit building corridor.
