Abstract:
1. An auto-controlling power saving system for solar energy street lamps, comprising: at least one street lamp; each street lamp having a light source at an upper end thereof, a battery set, at least one solar plate installed at an upper end of the light source for absorbing solar energy; absorbed solar energy being converted into electric power which is transferred to the light source for lighting up the light source or is stored in the battery set; and a main controller for controlling all electric powers of the elements of the system for power management; the main controller controlling actuation, de-actuation and illumination of all street lamps; the main controller being connected to the battery sots of the street lamps and the related elements used; the main controller having a plurality of power control modes for power management and illumination control of the at least one street lamp; and wherein when the number or the at least one street lamp is greater than two, the main controller calculates power of all the battery sets for all the street lamps so as to determine the illuminations of all street lamps; if the amount of charges of all battery sets are not sufficient to light up all the light sources, the main controller sets only some selected light sources light up with a predetermined illumination, namely, not fully light up.
