Working principle of microwave induction lamp

Microwave induction lamp emits electromagnetic waves through a planar antenna. When a moving object enters the electromagnetic wave environment, the waveform is reflected and folded back. When the planar antenna receives the feedback waveform, the subsequent circuit works after detecting the trigger signal.

Microwave induction uses the fourth generation light source as the luminous body, which has high luminous efficiency and low power consumption, and is not affected by the environment such as temperature, humidity, light, airflow and dust. Long service life, safety and reliability. Can be widely used in underground parking lots, corridors, aisles, public toilets, elevators and other indoor and outdoor lighting.

Induction lamp can be divided into three categories according to the induction mode: 1, voice-activated induction lamp 2, infrared induction lamp 3 and microwave induction lamp. The microwave induction lamp can be divided into 10.525G microwave induction and 5.8G microwave induction. Because 10.525G microwave induction has no shielding filtering, the signal output and reception are not very stable, the anti-radio interference ability is poor, and the transmitting angle of the non-transmitting antenna is narrow. Fenghua Chunzhi Electronic Technology Co., Ltd. developed and invented a 5.8G microwave induction module for lamps, which solved the problem of 10.
