Description

Technical Field

[0001] The utility model relates to the technical field of electronic circuits, and in particular to a sensor-controllable start-stop driving circuit and a lamp. Background Art

[0002] Intelligent control is becoming increasingly popular in people's lives. For example, in intelligent controlled lamps, a human body sensor module is set on the driving circuit of the lamp. When the user enters the room, the human body sensor module senses the human body reaction signal, and the driving circuit can control the lamp to light up, and the lamp can be turned off when the user leaves the room.

[0003] However, in actual use, there are certain usage scenarios. For example, during the day, when the user enters the room, the lamp will automatically light up, resulting in energy waste, or when the user leaves the room, he does not want to turn off the lamp, but the lamp will be automatically controlled by the driving circuit and go out.

[0004] Therefore, in the future, a subroutine for starting and stopping the human body sensing function will be set in the logic program of the driving circuit. When the user wants to disable the human body sensing function, the subroutine can shield the human body response signal. However, the logic control is relatively complex. After long-term use, the software program may become disordered, resulting in logic control failure and failure to start and stop the human body sensing function normally. Utility Model Content
