Microwave radar sensing LED bulb principle
Using the Doppler principle, microwave induction lamps emit high frequency electromagnetic waves (5.8 GHz) and receive their echoes, which detect changes in the echoes and detect small movements within the range, and then the microprocessor triggers the lighting fixtures . The signal can pass through thin wooden doors, glass panels and thin walls. The microwave detection angle of this product is 360 degree omnidirectional detection, especially suitable for residential corridors, as well as energy-saving automatic lighting places such as corridors, toilets, basements, garages, warehouses, and monitoring.
Features of microwave radar sensing LED bulbs
1, long service life: long life: 30,000 hours;
2, reliable and durable: no tungsten wire, the possibility of abnormal scrap is very small, the maintenance cost is extremely low;
3, radar sensing function: use Doppler effect to make a moving object light, enter full negative state, power 4W, and delay about 20 seconds; no moving object trigger, the light is off;
4, sensing distance: 5-8 meters, 360 degrees under the lamp;
5, light control function: when the environment has light, it does not work at all; when the environment is dull (8-10LUX), it enters the induction controlled state.
