Garage sensor light principle
Garage induction light principle: Garage induction light is a new type of intelligent lighting product that automatically controls the light source to light up through the induction module, and the garage induction light adopts industrial area-level chips, which has a wide load capacity and strong anti-interference ability.
Garage sensor light principle
The garage induction light uses the Doppler effect principle to transmit electromagnetic waves through a planar antenna. When a moving object enters the environment of electromagnetic waves, the waveform is reflected and folded back. When the planar antenna receives the feedback waveform, the subsequent circuit will work after detecting the trigger signal. As a result, the dual brightness effect of bright / slightly bright is produced, and the comprehensive weighted power is only 5-6W, which is more than 85% energy-saving than ordinary fluorescent lamps, and the lifespan is greatly prolonged. Compared with human pyroelectric induction and voice-activated induction, the induction distance is longer, the angle is wider, there is no dead zone, it can penetrate glass and thin wood, and it is not affected by the environment, temperature, dust, etc. In the case of 37 degrees, the sensing distance will not be shortened, the reflection speed is fast, and the concealment is good. It is an essential lighting fixture for underground garages.
