Solar street light system

Street lights are indeed a good thing. They have always been compared to the beacon light, but now the street light system in many cities has been changed and no longer consumes electricity. There is a solar street light system that uses solar energy to convert light energy to provide energy. , So let's take a look at how it works!

Solar street light system-principle of solar street light system

Solar street lights are made of solar cells using the principle of photovoltaic effect. Day solar panels receive solar radiant energy and convert it into electrical energy output. It is stored in the battery through a charge and discharge controller. At night, when the illuminance gradually drops to 10 lux, solar energy The open circuit voltage of the battery board is 4.5V, and the charge and discharge controller will act after detecting this voltage value, and the battery will discharge the lamp cap. After the battery is discharged for 8 hours, the charge and discharge controller will act, and the battery will be discharged. The primary function of the charge and discharge controller is to maintain the battery.

Solar street light system—composition of solar street light system

The system is composed of solar cells (including brackets), LED lamp holders, control boxes (with controllers and batteries), and light poles; the light efficiency of solar panels reaches 127Wp/m2, with high efficiency and resistance to the system The wind design is very advantageous; the lamp holder part uses 1W white LED and 1W yellow LED integrated on the printed circuit board and arranged in a dot matrix with a certain interval as the plane light source.

Solar street light system—the advantages of solar street light

1. Wide range of energy: Solar street lights use solar photovoltaic cells to provide electricity. Solar energy is a green and environmentally friendly new energy source, 'inexhaustible and inexhaustible.'

2. The installation is simple and convenient: the installation of solar street lights is simple and convenient. There is no need to lay cables and other basic works like ordinary street lights. It only needs a base to fix, and all the wiring and control parts are placed in the light rack. In, form a whole.

3. Low maintenance cost: The solar power supply used by solar street lights, except for a small part of the electricity cost when converted to city power supply in rainy days, is almost zero in operating costs. The operation of the entire system is automatically controlled, without human intervention, and almost no maintenance cost.

In fact, the current street lights are not only solar street light systems, but many cities have replaced them with solar and wind power supply systems. Solar energy works on sunny days, and wind energy is converted on rainy days. We all believe that the night life will be filled with brilliance. In the near future, the energy required by more of our equipment will be replaced by sustainable energy!
