Analysis of the specific working principle of solar LED street lamp battery components

1. Introduction to the basic composition of the solar LED street light system. The solar LED street light lighting system is composed of solar cell components (including brackets), LED light sources, control boxes (with controllers and batteries), and light poles; solar panels light The effect can reach 127Wp/m2, the efficiency is high, and it has very good wind resistance. The lamp holder part is integrated with 1W white LED and 1W yellow LED on the circuit board and arranged in a dot matrix with a certain interval as the plane light source. The control box is made of stainless steel, which is beautiful and durable. There are maintenance-free lead-acid batteries and charge and discharge controllers in the control box. This solar LED street light lighting system uses valve-controlled sealed lead-acid batteries. It is called a maintenance-free battery, which helps to reduce maintenance costs; the design of the charge and discharge controller takes into account complete functions (with light control, time control, overcharge protection, overdischarge protection and reverse connection protection, etc.) and cost control. High cost performance. 2. Simple working principle introduction The working principle of the solar cell module system is simple. The solar cell panel is made using the principle of photovoltaic effect. During the day, the solar cell panel receives solar radiation energy and converts it into electrical energy output, which is stored in the battery through the charge and discharge controller. At night, when the illuminance is gradually reduced to about 10lux and the open circuit voltage of the solar panel is about 4.5V, the charge and discharge controller will act after detecting this voltage value. The battery will discharge the lamp holder. After the battery is discharged for 8.5 hours, the charge and discharge controller will act. When the discharge is over, the main function of the charge and discharge controller is to protect the battery.
