Radar induction lamp induction principle: using the principle of Doppler effect, independent research and development of the plane antenna transmitting and receiving circuit, intelligent detection of the surrounding electromagnetic environment, automatic adjustment of the working state, triggering work by moving objects: when the moving object enters the sensing range, the light is on; when the moving object leaving, there is a delay of 30 seconds, the light will be off or the light will be slightly bright, so as to achieve the effect of intelligent power saving.
Human body infrared sensor lamp sensing principle: human body pyroelectric infrared, the human body has a constant body temperature, generally at 37 degrees, so it emits infrared light with a specific wavelength of about 10um. The passive infrared probe detects the infrared light emitted by the human body to work. The infrared rays are enhanced by the Philippine filter and concentrated on the infrared sensor source. Infrared induction sources usually use pyroelectric elements, which lose charge balance when the temperature of the infrared radiation of the human body changes, and discharge charges outward. The subsequent circuit can only trigger the switching action after detection and processing.
