Fire escape responsive Inductive Lamp holder

Principle of light induction lamp: infrared induction switch is an automatic control switch based on passive infrared sensing technology, and the main induction device is a pyroelectric infrared sensor for human body. The human body temperature is generally 37 degrees, will emit a wavelength of about 10 microns of infrared, and the temperature around the human body is generally lower than 37 degrees, greater than the wavelength of human infrared radiation, pyroelectric infrared sensor is to detect changes in infrared radiation in the area to work. The infrared induction switch based on pyroelectric infrared sensing technology does not emit any type of radiation itself, and the power consumption is very small. During the day, the switch is closed under the action of light control. When someone enters the sensing range at night, the sensor detects the movement and change of the infrared spectrum of the human body, and the switch is automatically switched on and the light is on. If the person does not leave, the switch will always be on. After the person leaves, the switch will automatically turn off the light after a delay of a period of time.

Microwave switch: Microwave induction (also known as radar induction) is now widely used in underground garages, road lights and other places. It uses a radar-like working principle by transmitting microwaves to detect moving objects, and then produces the corresponding switching operation. It has a strong ability to resist radio frequency interference, is not affected by temperature, humidity, light, air flow, dust, etc., and can be installed in a certain thickness of non-metal shell, without exposure, while realizing the induction function, but also to maintain the overall coordination and beauty of the appearance.
