However, lighting also consumes a lot of energy. Therefore, how to effectively control and optimize the power consumption of light sources has become an important research topic. At present, research on light source power consumption has made some progress, but there are still some problems and challenges.

[0003] First, different light source types and specifications have different luminous efficiency and power consumption characteristics. For example, LED lamps have higher luminous efficiency and longer service life, but their power consumption is also relatively high.
