Document Type and Number:
WIPO Patent Application WO/2019/059525
Kind Code:
A1
Abstract:
Provided in one embodiment of the present invention is a photovoltaic lighting system comprising: an MPPT circuit unit for controlling a battery charging voltage by calculating the maximum power point of electrical energy generated from a photovoltaic panel; a battery charging unit for charging and discharging, in a battery, the electrical energy controlled by the MPPT circuit unit; a lighting unit in which a plurality of LEDs are combined; a lighting driver for turning on or off the lighting unit by supplying power supplied from the battery; and an integrated control board including a microprocessor, which checks a residual quantity of the battery, overcharging of the battery, a discharge quantity, a discharge time, and a lighting state and brightness of the lighting unit through the MPPT circuit unit, the battery charging unit, and the lighting driver so as to diagnose an error and perform integrated control.
