The lamp module is a lighting device capable of recording and controlling a lamp state. The lamp state model memory module is configured to store the generated lamp state model. The lamp state model calculation module is configured to calculate the lamp state model. The lamp state model application module is configured to call the lamp state model from the lamp state model memory module and apply the lamp state.

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.

Abstract: A method for calculating a current illumination level of a target scene capable of quantitatively evaluating an illumination level in a scene through a camera, and a method for automatically adjusting an illumination level of the target scene capable of automatically performing a constant light control over a scene, and a camera, capable of quantitatively evaluating the illumination level in the scene and a smart illumination control system are provided. The smart illumination control system is capable of quantitatively evaluating the illumination level in the scene and automatically adjusting an illumination brightness, a color temperature, a color or a contrast in the scene to realize a constant control over a light environment. In addition, by setting the illumination level on a setting terminal, an illumination product also performs a light-supplementing automatically for the camera to realize a constant light control over a shooting.
