1、General Overview

With the rapid development of China's economy and the increasing demand for energy, the problem of energy shortage has become an important issue affecting the rapid development of China's economy. The full development and utilization of solar energy is a sustainable energy strategic decision of governments around the world.Solar outdoor lighting has stood out from other technologies, it provides the necessary lighting for our daily lives.

1. Features Of Solar Lights
   2.1、 Low cost: high brightness, low power consumption, lower solar cell and battery pack configuration, and lower cost.

2.2 Long life: The quality guarantee period of monocrystalline silicon or polycrystalline silicon solar modules is 20 years. After 20 years, the battery modules can continue to be used, but the power generation will be slightly reduced. The super bright white LED has a service life of up to 100,000 hours, and the intelligent controller has low static power consumption and a long service life.

2.3、 Reliability and stability: Monocrystalline silicon or polycrystalline silicon solar modules are resistant to typhoons, moisture, and ultraviolet radiation.

2.4、Unattended: There is no need for management personnel during operation, and the perfect intelligent control system gives users enough peace of mind.

2.5、Power supply for more than 10 hours: The system design takes into account the local rainy weather, and stores the average excess electric energy in the battery to ensure that the user has enough electric energy for continuous rainy days.

Coupled with the use of solar-powered LED lamps, one does not need to erect or bury power lines; two does not require electric power from the grid; three does not require maintenance. It is really an investment and a lifelong benefit.

3、 The Working Principle Of Solar LED Light
As shown in the figure: the sunlight shines on the solar modules during the day, so that the solar modules generate a certain range of DC voltage, convert the light energy into electric energy, and then transmit it to the intelligent controller. After the overcharge protection of the intelligent controller, the solar energy The electrical energy transmitted by the modules is sent to the storage battery for storage; at night, the solar modules cannot receive light energy, and when the output DC voltage drops to nearly zero, the intelligent controller automatically turns on the control device to provide electrical energy to the LEDs to prompt the LEDs to generate electricity. The light source emits sufficient brightness for lighting; when it is dawn, when the solar module receives the light energy to generate voltage, the intelligent controller automatically switches to the charging mode to work.
