The light supply condition may include an environmental condition and a power condition. The street lamp 1 control subsystem collects environmental information through a pre-configured sensor to generate the environmental condition. The charge condition is generated based on the first charge value and the second charge value. And the street lamp 1 control subsystem determines a light supply strategy from the light supply meter according to the light supply condition and controls the working power of the street lamps 1 of the regional group through the light supply strategy.
