Abstract
The disclosure provides a method and a system for adjusting an irradiation angle of a lamp and a lamp with adjustable irradiation angle. The lamp includes a plurality of infrared receivers and a driving motor. The method comprises: receiving an infrared signal from a remote controller via the plurality of infrared receivers; determining an irradiation angle adjustment value of the lamp based on a plurality of infrared signal intensity values of the plurality of infrared receivers; adjusting an irradiation angle of the lamp via the driving motor based on the irradiation angle adjustment value. In the technical scheme provided by the example of the disclosure, when the irradiation angle of the lamp needs to be adjusted, the irradiation angle of the lamp is controlled only by operating the remote controller.
