Patent ID: 10292239

Abstract:
A lighting energy saving method of the present invention, comprises a plurality of brightness adjustable illuminants, and a plurality of photoreceptors for detecting brightness of lighting environment, the brightness of lighting environment is brightness of the environment formed by illumination light emitted from all the illuminants, natural light and illumination light emitted from other lighting systems, wherein comprising: A. setting basic illumination brightness of the lighting environment, i.e. setting basic photosensitivity value of each of the photoreceptors; B. adjusting illumination brightness of each illuminant to a corresponding brightness value to obtain a real-time brightness environment of the lighting environment, and then detecting the real-time brightness environment by the photoreceptors to obtain the photosensitivity values detected by the photoreceptors, the photosensitivity values reflecting the real-time illumination brightness of the real-time brightness environment; C. comparing the detected photosensitivity values actually detected by all the photoreceptors to their own basic photosensitivity values, determining whether their own basic photosensitivity values are satisfied, if not, repeating B, if so, entering D; D. all the illuminants lighting according to the brightness that they should have at the real-time brightness environment.
