While the induction lamp saves energy, it also greatly facilitates people's lives. Install induction cabinet lights on the cabinets, which will turn on when the door is opened and turn off when the door is closed, which is much more convenient. But is it better for induction cabinet lights to use human induction cabinet lights or hand-swept induction cabinet lights ? Let's first understand the working principle of infrared induction cabinet lights.

The human body temperature is constant at about 37 degrees, so it emits infrared light of a specific wavelength of about 10um. The passive infrared probe of the human body pyroelectric infrared sensor is to observe the infrared light of about 10um when the human body rises to work. The human body pyroelectric infrared sensor is the main component of infrared induction.

Generally speaking, the pyroelectric element used in the infrared induction source loses the charge balance when the temperature of the infrared electromagnetic radiation of the human body is changed, and the charge is released outward. The subsequent circuit can trigger the switch after the detection process. When the dedicated sensor detects the change of the infrared spectrum of the human body entering the switch sensing range, it will automatically switch on the switch load. When the person does not leave the sensing range, the switch is continuously turned on, but when the person leaves or there is no action in the sensing area, the inductive switch will delay and automatically shut down the load.

At this point, the cabinet light with the human body sensor switch looks very convenient, but the infrared sensor is too far away, it is easy to be triggered by mistake, resulting in waste of electricity, so Jedver recommends to swipe the cabinet light with the sensor switch, such as IR Thin panel light (infrared sensor), ultra-thin product shape design, side light emitting and no LED spots, waterproof level up to IP20, equipped with screws and 3M adhesive, simple installation and operation, lifespan of more than 50,000 hours, energy saving and environmental protection.
