At present, the brightness of a lamp can be controlled by a microwave induction lamp, and the general control process is as follows: if the moving object is detected, the lamp is turned on, and if the moving object is not detected, the lamp is controlled to be turned off after a period of time delay; or a second type: if the moving object is detected, the lamp is turned on, and if the moving object is not detected, the brightness of the lamp is adjusted to be the lowest after a period of time delay, and the lamp is always kept on. For the first, if the human body is just temporarily left, the lamp is directly extinguished, and when the human body returns to the range of the lamp again, the lamp can be awakened again, and in the process, the user is inconvenient due to the fact that the lamp is extinguished.
