What is solar street light system? Working principle, technical features and application scenarios
Solar street lamp is a street lamp that uses solar energy to charge and emit light. It is composed of solar panel, controller, LED light source, battery, bracket and other components. The solar panel converts solar energy into electricity to charge the battery, the controller monitors the battery power, and when the light is dark, the controller automatically turns on the LED light source to provide lighting.
First, the working principle of solar street lights
The working principle of solar street lights is to collect solar energy through solar panels, and convert it into direct current energy, stored in the battery pack, and then control the switch and brightness of LED lamps through the controller to achieve the lighting of street lights. When the solar panel collects enough sunlight during the day, the battery pack stores enough electricity, and once the night comes, the controller in the three thousand smart street lamp system will automatically turn on the LED lamp and use the stored electricity for lighting. At the same time, the solar street lamp is also equipped with intelligent light control and time control system, which can automatically adjust the lighting time and brightness of the lamp according to the change of weather and light, in order to achieve the effect of energy saving.
Second, the technical characteristics of solar street lights
The technical characteristics of solar street lights are as follows:
High photoelectric conversion efficiency: solar street lights use efficient solar panels, which can convert sunlight into electricity, and its photoelectric conversion efficiency can generally reach 15%-20%.
Environmental protection and energy saving: solar street lights do not need external power, completely rely on solar energy to charge, reduce the dependence on traditional energy, but also reduce energy consumption, is a kind of environmental protection and energy-saving green energy.
Easy installation: solar street lights do not need to lay cables, avoiding the problem of difficult construction and high cost, and it is relatively simple and convenient to install, while it will not cause damage to the landscape.
Low maintenance costs: Since solar street lights mainly rely on sunlight for charging, their maintenance costs are low, and only regular inspection and cleaning of components such as solar panels are required.
Long life: solar street lights have a long service life, generally up to more than 5 years, so it is also more economical, but also reduce the pollution to the environment.
Third, the use of solar street lights
Solar street lights are suitable for street lighting of roads, squares, parks, communities, factories, schools and other places, especially some remote, mountainous, desert and other places that cannot be connected to the power supply, it can provide continuous lighting for these places. At the same time, three thousand smart solar street lights also have the advantages of energy saving and environmental protection, easy installation, simple maintenance, etc., which can reduce the electricity cost of lighting and reduce carbon dioxide emissions. Therefore, under the advocacy of some environmental protection, energy saving and consumption reduction, the application of solar street lights has gradually been promoted and popularized.
Four, the design of solar street lights
Solar street lamp design points include:
1. Use high-efficiency solar panels to ensure fast charging in sufficient sunlight.
2. Choose high-quality LED light source to ensure long-term stable operation of street lights.
3. The use of intelligent control system can adjust the brightness and switching status of the light in real time according to the weather and lighting conditions to extend the service life of the street lamp.
4. The use of efficient battery management system can ensure the long-term service life and stability of the battery.
5. Consider the waterproof and dustproof capability of the street lamp to ensure that the street lamp can run stably in the outdoor environment for a long time.
6. Easy to install, maintain and replace the design, easy to manage and maintain.
7. For different application scenarios, different street lamp types and configurations can be selected according to different needs.
Fifth, the development trend of solar street lights
Solar street light is a green, environmentally friendly, energy-saving street light, which has great potential in the future development. The following is the trend of the development of solar street lights:
Technology is becoming more and more mature: with the continuous progress and development of solar technology, the technology of solar street lights is also constantly improving, including solar panels, energy reserve systems, LED lights and other aspects.
Energy saving and environmental protection: the solar panels used in solar street lights can convert solar energy into electricity, which does not require power supply from the grid, and the LED lamps used are also more energy saving and environmental protection than traditional street lights, so three thousand smart solar street lights will become the mainstream of future street lights.
The application field is expanding: solar street lights can be installed in various places such as squares, parks, airports, docks, highways and so on according to needs, and can also be used as disaster emergency lighting equipment.
Intelligent: With the development of science and technology, solar street lights will not only be a simple lighting equipment, but also join the intelligent design, which can achieve accurate control of all aspects of light brightness, time, position and so on through the network control system.
Charging pile integration: At present, the panels and battery packs of many solar street lights have a large capacity, which can meet the electricity needs of street lights, and can also provide charging services for electric vehicles, so three thousand smart solar street lights will also join the charging pile function of electric vehicles in the future.
