Solar LED street lights have a bright future

　　 Solar street lamp manufacturer Chang Hui Lighting found that the market prospect of LED lighting is very broad. Related data shows that global lighting electricity consumption accounts for about 20% of total electricity consumption. As the largest application market for LED lighting, landscape lighting accounts for about 43% of the market. It is estimated that 30% of the world's street lights will switch to solar LED integrated lighting systems, which can save 460 billion kilowatt-hours of electricity each year. A solar energy engineering expert believes that LED street lights will become one of the development directions, but currently their performance is unstable, high cost, and short life span, so technical breakthroughs are still needed.

　　The promotion of solar LED street lights in recent years has found a combination of solar energy and LED lighting. Solar LED street lights add solar panels and special storage batteries, and at the same time replace ordinary sodium lights with LED lamps. During the day, the solar energy is collected through the battery panel, and then converted into direct current and stored in the battery; at night, the battery is powered to provide electricity for the lamps. At present, the price of solar street lights is relatively expensive, about 3 times that of ordinary street lights, but its later maintenance cost is low. As the solar street lights adopt decentralized circuit control, the switch and energy conversion of the street lights are all intelligently controlled without manual operation, thus reducing maintenance costs.

　　 Since 1998, the application of solar LED lamps has entered a new stage. However, this kind of lamps also has many shortcomings. For example, the longest lifespan of its main component resistors and triodes does not exceed 8000 hours, which means that the solar LED lamps have only 8000 hours of life. Therefore, how to extend the service life of solar LEDs has always been a problem that plagues the industry.

　　 Compared with traditional street lights, solar LED street lights have the advantages of energy saving, environmental protection, convenient construction and convenient maintenance, but their current performance is not stable, the energy storage battery needs to be replaced, and the high price will hinder its further application. .
