The magnetically controlled light is composed of two parts. It is composed of an LED light with a magnetically controlled switch and a magnet. It is installed on both sides of the door that can be opened separately. When the door is closed, the magnetic force is induced to turn off the LED light with a magnetically controlled switch. When the magnetic area does not sense the LED light with a magnetically controlled switch, the light will light up. That is, the door is on, and the door is off. (2) after the magnetically controlled lamp is fully charged, turn on the OFF/ON switch, the LED lamp enters the normally bright state, the magnetically controlled switch and the magnet are induced, the magnetic induction area is within 2CM, and the LED lamp goes out in the magnetic induction area. when the LED lamp leaves the magnetic induction area, the lamp is on;
