Abstract
A method for rapidly and quantitatively adjusting a beam angle of an illuminating device includes: determining a target beam angle according to an actual scene, and sending, by using an input apparatus, the target beam angle to the illuminating device; receiving, by a receiver of the illuminating device, the target beam angle and sending the target beam angle to a controller of the illuminating device; determining, by the controller of the illuminating device, target power of each light source according to the target beam angle and a parameter table stored in a local read-only memory (ROM) or cloud of the illuminating device; and driving, by a driver, each light source to emit light according to the corresponding target power, enabling radiated light to be mixed in an illuminated space to change the beam angle, and obtaining the target beam angle according to a superposition principle for the intensity of light.
