Description

The YX8018 is the two 1.25V charge current or one Lights in a stable manner LED in the pond. Light of the sun Saw And to charge the rechargeable battery and a battery hit the error, The point the LED in the charging battery is charged to at night Light, automatic switching.

It is a switch-mode power supply (SMPS) designed for LED lighting systems and can operate with a wide input voltage range, making it suitable for various applications.

What is Solar LED Driver?

A solar LED driver is a device that is used to power and control LED lighting systems that are powered by solar panels. Solar LED drivers typically include a DC-DC converter, which converts the variable DC output from the solar panel to a stable DC voltage suitable for powering the LED.

One of the key advantages of solar LED drivers is that they allow LED lighting systems to be powered by renewable energy sources, such as solar power. This can significantly reduce energy costs and environmental impact compared to traditional lighting systems that are powered by grid electricity or fossil fuels.

YX8018 Circuit

The main functions are charge control, boost drive, light control, low voltage protection and so on. The solar lawn lamp mainly uses the energy of the solar cell to work. When the daytime sunlight is irradiated on the solar cell, the light energy is converted into electric energy and stored in the battery, and then the battery is provided for the LED (light emitting diode) of the lawn lamp at night. power supply. Its advantages are mainly safety, energy saving, convenience, and environmental protection.
