Abstract:
A sensor light is provided. The sensor light includes a sensing circuit, a control circuit, a driver circuit, a light-emitting circuit, a first power supply circuit, and a second power supply circuit. The sensing circuit is configured to detect that a first trigger event occurs in a region and send a first trigger signal to the control circuit. The control circuit is configured to receive the first trigger signal, send a second trigger signal to the driver circuit, and send a third trigger signal to the second power supply circuit when the first power supply circuit is not supplying power. The driver circuit is configured to receive the second trigger signal and drive the light-emitting circuit to emit light.
