Description

Energy-saving inductive switch

Technical Field

The utility model relates to the technical field of electrical elements, in particular to an energy-saving inductive switch.

Background

The inductive switch is an intelligent human body infrared inductive switch, and is a switch which is automatically started when a person passes through an infrared induction detection area. The main device of the human body infrared induction switch is a human body pyroelectric infrared sensor. The human body has a constant body temperature, generally 37 degrees, so that the infrared probe emits infrared rays with a specific wavelength of about 10 μm, and the passive infrared probe detects the infrared rays with the wavelength of about 10 μm emitted by the human body to operate. Infrared rays with the wavelength of about 10 μm emitted by a human body are enhanced by a Fresnel filter and then are gathered on an infrared induction source. The infrared induction source usually adopts a pyroelectric element, the element loses charge balance when receiving the change of the infrared radiation temperature of a human body, charges are released outwards, and a subsequent circuit can trigger the switch to act after detection processing. The person does not leave the sensing range, and the switch is continuously turned on; after the person leaves or has no action in the sensing area for a long time, the switch automatically delays to turn off the load.

The inductive switch can control the lighting lamp to be turned off by sensing whether a person exists in the environment to realize the energy-saving effect, but the switch can turn off the load if the movement of the human body is not detected during use, and students cannot generate position movement for specific use scenes such as school study rooms, but still have lighting requirements, and the traditional inductive switch cannot meet the use requirements at the moment.
