The Solar Street Light
system is composed of solar cell components (including brackets), LED lamp holders, control boxes (with controllers and batteries), and light poles; the light efficiency of solar panels reaches 127Wp/m2, which has high efficiency and is very effective for the system. The wind-resistant design is very advantageous; the lamp holder part uses 1W white light LED and 1W yellow light LED integrated on the printed circuit board and arranged as a dot matrix with a certain interval as the plane light source.
The control box body is made of stainless steel, which is beautiful and durable; maintenance-free lead-acid batteries and charge and discharge controllers are placed in the control box. This system uses long-life lithium batteries, which are also called "maintenance-free batteries" because they are rarely maintained, which is conducive to reducing system maintenance costs; the charge and discharge controller is designed with full functions (with light control, time Control, overcharge protection, overdischarge protection and reverse connection protection, etc.) and cost control to achieve a very high cost performance.
The working principle of Solar Street Light is introduced. The working principle of the system is simple. The solar cell made by the photovoltaic effect principle during the day receives solar radiation energy and converts it into electrical output. It is stored in the battery through the charge and discharge controller, and is used as the illuminance at night. It is gradually reduced to about 10lux and the open circuit voltage of the solar panel is about 4.5V. After the charge and discharge controller detects this voltage value, it will act, and the battery will discharge the lamp cap. After the battery is discharged for 8.5 hours, the charge and discharge controller will act, and the battery discharge ends. The main function of the charge and discharge controller is to protect the battery.
