A 1000w solar light can illuminate 100 square meters. 1000 watts of lumen is equivalent to a 120W to 220V white paper bulb. Calculate 20 square meters accordingly. The brightness of a 1000w floodlight is 5 times the above data, so it can illuminate 100 square meters.

According to luminous efficiency, 1000 watts of lumen is equivalent to the light emitted by a 100W to 220V white paper bulb, according to luminous flux.

The working principle of solar lamp is simple. It is a solar cell made by the principle of photovoltaic effect. During the day, the solar panel receives solar radiation and converts it into electrical energy output, which is stored in the battery through the charge and discharge controller. At night, when the illumination gradually decreases to about 101ux and the open circuit voltage of the solar panel is about 4.5V, the charge and discharge controller detects this voltage value and acts, and the battery discharges to the lamp head.

After the battery discharges for 8.5h, the charge and discharge control acts and the battery discharge ends. The main function of the charge and discharge controller is to protect the battery. Solar lamps are electric lamps that convert solar panels into electrical energy. During the day, even on cloudy days, this solar generator solar panel can collect and store solar energy. As a safe and environmentally friendly new electric lamp, solar lamps are becoming more and more important.
