Sound and light-controlled ceiling lamp
Shanghai Lujean electronic energy saving ceiling lamps, use sound waves or body heat infrared rays as controling source to automatically handle lamps' on and off, which avoid the trouble of often using switch. At the same time, it can automatically prolong the lighting time before black out. As it is more efficient, much safer, no sparking, and more lasting. Now it's widely used in aisles, restrooms and other public places.

Function and Features:
1. Use sound waves as controlling source, combined sensor technology with lighting technology. Widely used in aisles, corridors, restrooms and other public places.

2. Interiorly installed volume sensor, it can automatically open, prolong to work and goes out. No need to install switches, convenient and efficient.

3. Have Circumstance Brightness Monitoring Circuit, turn on automatically only when lighting level is below the fixed data, which is more energy-saving. (also can be designed into all day sensitive)

4. Have a signal terminal can connect to fire-protection system.
