Abstract
The utility model relates to a solar LED street lamp control device, which comprises a solar photoelectric conversion circuit, a control circuit and an LED light source, wherein the solar photoelectrical conversion circuit comprises a solar cell panel and a battery. The solar LED street lamp control device is characterized in that the control circuit comprises a first resistance, a second resistance, a first triode, a second triode and a voltage stabilizing diode which is conducted and stopped according to the output voltage value of the battery for preventing the over-discharging of the battery. Only one voltage stabilizing diode is adopted to provide the reference voltage to the control circuit, thereby preventing the battery from damaging caused by the over-discharging. The solar LED street lamp control device has the advantages of precise control voltage, stable and reliable circuits and small power consumption, compared with the method of providing control voltage by a divider resistance. The control device is suitable for the control of over 3.5V large power LED street lamps.
