Introduction to solar street lights
Solar street lights are composed of the following parts: solar panels, solar controllers, battery (lithium battery or gel battery), LED street light, lamp post and cable.
1.Solar panel
Solar panels are the core part of solar street lights. Its function is to convert the sun’s radiation capacity into electrical energy, which is sent to the battery for storage. Among the many solar cells, the more common and practical are mono crystalline silicon solar cells, poly crystalline silicon solar cells and amorphous silicon solar cells.
2.Solar controller
Regardless of the size of the solar fixture, a well-performing charge-discharge controller is essential. In order to extend the service life of the battery, its charging and discharging conditions must be limited to prevent the battery from overcharging and deep charging. In places with large temperature differences, qualified controllers should also have temperature compensation functions. At the same time, the solar controller should have both street lamp control functions, light control, time control functions, and should have the function of automatic cutting and controlling load at night, which is convenient for extending the working time of street lights in rainy days.
3.Lighting source
Solar street lights are all using LED chips, the brand of the chip and the number of chips is different, So is lumens.
4.Lamp post
The height of the lamp pole should be determined according to the width of the road, the spacing of the lamps, and the illuminance standard of the road.
The history of solar street lights
Solar street lights were originally mainly used in third world countries or remote and disaster areas, where electricity was not always available. Today’s developments in solar technology and solar projects appear in both developed and developing countries.
Due to the unique advantages of solar photovoltaic power generation technology, solar cells have been used in the field of lighting soon after entering the practical stage. In China, solar cells were used on navigation beacon lights as early as the early 70s, when solar beacon lights were installed in Tianjin Port. Immediately afterwards, in order to solve the lighting problem in areas without power supply, solar lighting is increasingly appearing. In the south of our country, solar tapping lamps and many other solar lighting lamps have appeared.
The current situation of solar street lights
In recent years, with the clean and environmentally friendly energy of solar energy being familiar to the public, solar lamps are also in the ascendant. Solar street lights, garden lights, and landscape lights are more and more widely used, and solar street lights are gradually entering people’s field of vision. It has been widely recognized by the society for its advantages of no need to lay cables, no consumption of conventional energy, and long service life, and many cities and villages have also begun to promote the use of solar street lights in some areas and some roads in the form of experiments or demonstrations, and have received certain results.
With the rapid development of the solar power industry, the field of photovoltaic applications is gradually expanding, and various new photovoltaic products are emerging. In the lighting street lamp, as a combination of technology and art of solar lighting system – solar street lamp, has begun to be widely used in the United States, France, Japan and other developed countries in many regions, due to the significant increase in solar cell production and the improvement of national economic strength since China’s reform and opening up, solar lighting fixtures began to enter our lives; Western Bright Project, solar street lights, solar garden lights, solar lawn lights, solar landscape lights, solar craft lights… It is not only suitable for areas rich in solar energy resources, but also suitable for areas with rich solar resources and areas with available solar energy.
In these areas, it can be used for urban residential areas, high-end residential areas, garden villas, public green spaces, urban squares, road lighting, but also for household lighting and environmental lighting in remote villages where conventional energy is scarce and it is difficult to generate electricity with conventional energy, with a good cost performance.
The prospect of solar street lights
At present, international conventional energy prices are rising, domestic energy supply is tight, many cities have the embarrassment of power cuts, and energy substitution has risen to the height of national energy strategic security. As an unlimited renewable energy source, solar energy has gradually partially replaced the conventional energy of urban production and life.
As one of the most important ways to use solar energy, solar lighting has also attracted more and more attention from the energy industry and the lighting industry. At present, China’s solar lighting technology has been relatively mature, the reliability of solar road lamps has been greatly improved, and the solar lighting fixtures of advanced enterprises in the industry have reached or even exceeded the national lighting standards. In cities with energy shortages, power cuts and remote areas where electricity consumption is difficult, there is a strong generalizability. China has a successful promotion model for reference, solar lighting fixtures in China large-scale promotion conditions are ripe.
It is undeniable that due to the inherent advantages of solar lamps, it will surely become the new favorite of the lighting industry. Industry insiders believe that energy-saving and environmentally friendly solar street lights will be one of the directions of lamp development. In the long run, the prospects for solar lighting systems are good. People’s consumption focus is first of all practical, low cost, and the current use of solar power lighting system is based on China’s national conditions and people’s conditions research and development, cost-effective. Solar lighting will be popularized in the next ten years and become the development trend of the future lighting industry.
