The core principle of LIGHT CONTROLLED MERRY-GO-ROUND technology is to convert optical signals into electrical signals through photosensitive elements, and then control the switching or adjustment of circuits. The core of the light-controlled switch is a photoresistor (such as cadmium sulfide or cadmium selenide), whose resistance changes with the intensity of light
