The solar street light is a lighting device that uses solar energy to produce electricity. Its appearance dates back to the 1970s. At that time, due to the impact of the energy crisis, people began to look for alternatives to traditional energy sources. As a clean and renewable energy source, solar energy has gradually attracted people's attention.
The first solar street lights were made up of solar panels, batteries and LED lamps. Solar panels convert solar energy into electricity and store it in batteries. When night comes, the battery will automatically power the LED lights to realize the lighting function. This kind of solar street light can not only save energy, but also reduce environmental pollution, so it is well received by people.
With the continuous progress of science and technology, technologyThe technology of solar street lights is also constantly improving. Today's solar street lights not only have higher power generation efficiency, but also have more functions. For example, some solar street lights can detect surrounding light and human traffic through sensors, automatically adjusting brightness and switching. This not only saves energy, but also increases the lifespan of street lights.
Although solar street lights have not been around for very long, their scope of application is very wide. Solar street lights can be used in various places such as urban roads, rural roads, parks, squares, etc. Especially in some remote areas or places without power supply, solar street lights can provide reliable lighting services and improve the living conditions of local residents.
En addition to applications in cities and towns, solar street lights can also be used on some special occasions. For example, in outdoor activities, wild camping, emergency rescue, etc., solar street lights can provide temporary lighting services to facilitate people's activities and movement.
In general, the emergence of solar street lights dates back to the 1970s. It is the result of the search for alternative energy sources in the context of the energy crisis. Solar street lights not only save energy, but also reduce environmental pollution, so they are well received by people. With the progress of science and technology, the technology of solar street lights is also constantly improving, and its application range is becoming wider and wider. It provides reliable lighting services totowns and villages and improves the living conditions of populations.
How to select solar lights: 1. Look at the panel size when choosing solar panels, you should choose a suitable panel according to the space size and actual needs.
The most common specifications on the market are 19*22cm, 24*35cm, 35*35cm, 35*46cm and other specifications. The power and conversion rate of different specifications of CMB are generally different. It is recommended to choose anything above 18%.
2. Battery Size
Solar lights absorb heat through the panel, then store it in the battery so the light turns on when needed. So the size of the battery is also very critical. The larger the capacity of the battery you choose, the longer it can last.
In addition, there is also the number of battery cells. The modelThe base is 1 cell. If you want long battery life, it is recommended to choose 3 cells or 4 batteries.
3. Look at the number of lamp holders
The lamp holders of solar lights generally have several lamp beads. The larger the number of lamp beads, the greater the brightness emitted by the lamp. lamp. , if the user does not know how many sockets are needed, he can consult the trader.
In addition, the lamp head panel is also very important. It should be chosen with good light transmission so that it does not affect the brightness of the solar lamp.
4. Look at the material of the lampshade. There are many types of solar lights on the market. Depending on the material, there are plastic lamps and metal lamps. Generally, the price of plastic materials will be. much cheaper, but because of the lamp itself, the situation ofheating is serious, so it is recommended to choose aluminum alloy, which has more stable performance and longer service life.
