Background

The microwave induction lamp is also called as a radar induction lamp, is a novel lighting product, and a built-in microwave inductor intelligently controls the lamp to be on/off, namely when a moving object exists in an induction range, the lamp is fully on, when no moving object exists in the induction range, the lamp is automatically turned into a lamp-off state, the lamp is widely applied to places needing light for 24 hours such as underground garages, corridors and the like, and the moving object can be a human body, a vehicle and the like. At present, the microwave induction lamp can control the brightness of the 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: if the moving object is detected, the lamp is turned on, and if the object cannot be detected, the brightness of the lamp is adjusted to be the lowest after a period of time delay, and the lamp is kept turned on all the time. For the first, if the human body only leaves temporarily, the lamp is turned off directly, and the lamp can be waken up again when the human body returns to the range of the lamp again, in the process, the lamp is turned off, so that inconvenience is brought to users.
