With the development of the times, nowadays, solar street lights are a kind of traffic and road condition lighting that uses solar energy as the external power source of street lights. It can play a very important role in our city life. Our eyes on travel and nightlife. So do you know the working principle of solar street lights?
The working principle of solar street lights is to convert solar energy into electric energy to realize lighting. On the top of the street lights are solar panels, also known as photovoltaic modules. During the day, these polysilicon photovoltaic modules convert solar energy into electricity and store them in batteries, so that solar street lights can be controlled intelligently. Under the control of the device, the solar cell panel is irradiated by sunlight, absorbs the solar light and converts it into electrical energy, and the solar cell components charge the battery pack during the day. In the evening, the power is delivered to the light source through the control of the controller to illuminate people at night. In the evening, the battery pack provides power to the LED light source to realize the lighting function.
Solar street lights generate electricity through solar energy, so there is no cable, and there will be no leakage and other accidents. The DC controller can ensure that the battery pack is not damaged due to overcharging or overdischarging. It also has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection. No need to lay cables, no AC power supply, and no electricity bills.
Advantages of solar street lights:
1. Energy-saving and environmental protection: Solar street lights are energy-saving and environmentally-friendly products, which can not only beautify the rural environment and form a beautiful landscape, but also respond to the country’s call for “green lighting” and guide rural people’s energy-saving awareness.
2. Simple construction: The construction of traditional city circuit lights is more complicated. It requires earth-moving, digging, and occupation of farmers and other places, which can easily cause conflicts between the project and villagers and is not easy to construct; solar street lights are much more convenient in construction than city circuit lights. Only need to dig pits, no need to lay cables; integrated solar street lights can choose to dig pits and bury new poles like traditional solar street lights, or they can be installed on existing poles, walls and other supports, which greatly reduces Construction process.
3. Price advantage: The traditional city circuit lights are much cheaper than solar street lights when they are purchased, but the later costs are also higher, such as: replacement of accessories, components, electricity costs, maintenance costs, wiring and erecting poles, etc., solar street lights are almost No subsequent costs
4. Simple maintenance: The maintenance of traditional city circuit lights and solar street lights is more complicated, and you need to send someone to the local for maintenance. The maintenance process is more complicated. If the parts are incomplete, more time is wasted. Now many factories are reluctant to reinstall them. Go to the local for maintenance
Solar street lights have a series of advantages such as low carbon, environmental protection, safety and reliability, which are recognized by the majority of customers and have been vigorously promoted. Therefore, it can be widely used in urban main and secondary arterial roads, communities, factories, tourist attractions, parking lots and other places.
