Solar lamp manufacturers tell you how solar lamp works

The working principle of the solar lamp is very simple. The solar cell is made by the principle of photovoltaic effect. During the day, the solar cell panel receives solar radiant energy and converts it into electrical energy output, which is stored in the storage battery through the charge and discharge controller.

According to research data, the luminous efficiency of the solar panel reaches 127Wp/m2, and the lamp holder part uses 1W white LED and 1W yellow LED integrated on the printed circuit board into a dot matrix with a certain interval as the plane light source.
LED (Light Emitting Diode), also known as light-emitting diode, consumes only a few kilowatts of electricity in a thousand hours (ordinary 60W incandescent lamp consumes 1 kilowatt of electricity in 17 hours, ordinary 10W energy-saving lamp consumes 1 kilowatt of electricity in 100 hours), that is to say, solar battery The board stores electric energy, discharges the lamp holder at night, and the LED lamp glows and illuminates.
Compared with ordinary LED lights, solar lamps have built-in lithium batteries or lead-acid batteries, and are charged with one or more solar panels. The general charging time is about 8 hours, and the use time is as long as 8-24 hours.
And LED solar lamp has many advantages.
1. The light is healthy, the light does not contain ultraviolet and infrared rays, and does not produce radiation.
2. Green and environmentally friendly, it does not contain harmful elements such as mercury and xenon, which is conducive to recycling and utilization, and will not cause electromagnetic interference.
3. Protect eyesight, DC drive, no flicker.
