Problems solved by technology
The LED human body sensor lighting products currently on the market mainly include warm light (2700K-3000K color temperature), warm white light (4000K-5500K color temperature), and cool white light (5500K-6500K color temperature) LED lights with three color temperatures. The sensor switch is separated from the light bulb body in the lamp, which has disadvantages such as complex structure, difficult installation, inflexible use, low induction sensitivity, and high installation labor costs.
And it can only control LED products to emit light when there is an induction signal. If there is no induction signal, the LED induction product cannot be made to emit light. This will cause inconvenience to users in practical applications, and the scope of use is relatively narrow. It is inconvenient to popularize the consumer market.
In some special occasions, not only human body induction LEDs are used as ordinary LED lights, but the existing LED lights cannot realize

Description
technical field [0001] The invention relates to the field of LED lighting and control, in particular to a control circuit and method for a human body induction LED lamp that realizes multiple lighting functions. Background technique [0002] LED lamps are a new type of lamps, which are being vigorously promoted and applied because of their high brightness, long life, and low power consumption. The LED human body sensor lighting products currently on the market mainly include warm light (2700K-3000K color temperature), warm white light (4000K-5500K color temperature), and cool white light (5500K-6500K color temperature) LED lights with three color temperatures. The sensor switch is separated from the bulb body in the lamp, and has disadvantages such as complex structure, difficult installation, inflexible use, low induction sensitivity, and high cost of installation hours. And it can only control LED products to emit light when there is an induction signal. If there is no in...
