This paper proposed a feedback system for intelligent lighting evaluation. This method enables the evaluation and optimization of the illumination uniformity. An effective way to save energy for the area where the lightening needs to be particularly strengthened or weakened is introduced. In addition, with the increased uniformity of the lighting source, a clear and safe auxiliary lighting system can be provided for those who need to work in the lighting area. Furthermore, specified lighting is available for some key areas, which adds more flexibility to the lighting system.
