Abstract:
1. A lighting system comprising: a solar power generation section; a first step-up circuit which steps up a first output voltage generated by the solar power generation section to output a second output voltage; a control section which detects the first output voltage, the second output voltage and an input current of the first step-up circuit to control the first step-up circuit according to the result of the detection; a DC/AC conversion circuit which converts the second output voltage into an alternating-current voltage; a switch board into which the alternating-current voltage is fed; a lighting device which is driven by electric power output from the switchboard; and a lighting control section which controls illuminance of the lighting device by using the result of the detection obtained by the control section, wherein the solar power generation section includes: the control section performs maximum power point tracking control so as to maximize output power of the solar cell according to the result of the detection.
