Full interpretation of the working principle of LED solar street lamps - systematically sort out the power generation and storage lighting process

August 01, 2023

With the rapid development of environmental protection and new energy, LED solar street lights are being used more and more because of their green and environmental characteristics. So, what is the working principle of LED solar street lights? This article will give you a comprehensive analysis.

The work of LED solar street lights can be divided into three parts: power generation, power storage and lighting.

1. Power generation part

The solar panel on the top of the LED Solar Street Light is the core component of power generation. It uses the photoelectric effect of semiconductor materials to convert sunlight into electrical energy and realize the process of generating electricity. It does not need fuel when working, and it can generate electricity continuously as long as there is sunlight. It is a green and environmentally friendly power generation method.

Factors that affect the amount of power generated include sunlight, solar panel efficiency, etc. The annual average sunshine time in most areas of my country is 2000-3000 hours, the sunshine resources are better in the south, and relatively less in the north. Choosing panels with high conversion efficiency can increase power generation.

2. Power storage part

The electricity generated by the LED solar street light will be stored in the battery connected to the controller. Materials used in electricity storage batteries usually include lead acid, sodium sulfur, etc. A good battery must have the characteristics of long charge-discharge cycle life and low self-release rate, so that the electric energy generated by Ensure can be effectively stored.

The controller is the "brain" of the street lamp, which can track the working status, control charging and discharging, and protect the battery from overcharging and overdischarging. When choosing a controller, pay attention to matching the battery voltage and setting a reasonable lighting mode for the power generation.

3. Lighting part

When the light in the external environment is insufficient, the controller will use the electric energy in the battery to provide energy for the LED lamp bead, and the LED lamp bead emits light to realize lighting.

The advantages of high pearlescent efficiency, adjustable color temperature and long life of LED lamps make the lighting effect of LED solar street lamps significantly better than traditional high-pressure sodium lamps. The intelligent controller can also adjust the lighting mode according to the time and lighting conditions, such as dimming, timing, etc., to reduce energy waste.

To sum up, from power generation to power storage to lighting, the whole process of LED solar street lights is scientific and reasonable, and efficiently utilizes solar energy. It is a kind of green environmental protection traffic lighting equipment worthy of popularization and application. Correct matching of various parts of the system can not only reduce energy consumption, but also ensure sufficient and soft illumination on the road at night and improve road safety.
