Description

technical field [0001] The invention relates to the technical field of lamp switches, in particular to a lamp switch chip and a control method for the lamp switch chip. Background technique [0002] With the development of electronic technology, lamp switches are becoming more and more intelligent. For different application scenarios, there are different intelligent requirements for light switches. For example, for light switches used in public areas such as corridors, garages, and stairwells, the lights are required to be turned on when people are in the room and turned off when people leave to save power. At present, the lamps and lanterns used in public areas such as corridors, garages, and stairwells generally use voice-activated sensor switches. However, in the actual use process, since people may stay in public areas such as corridors, garages, and stairwells for a period of time, if the lamps are turned off automatically after being on for a few seconds, it is necess...
