A source of light is an electric bulb of the LED. It is an electric bulb with a sensor equipped with a feeling of person sensor and a brightness sensor. I sense the infrared rays of the person and automatically turn on and can turn off the light. I automatically light it for 90 seconds when I sense it. I automatically turn off the light, but turn on successively afterwards if I sense a person.
