The technology of solar street lights and LED street lights needs to be improved

Although LED street lamps are more expensive than ordinary street lamps in terms of cost, from the perspective of energy saving, the energy saving advantages of LED street lamps are relatively large. In order to improve energy efficiency, the design of solar energy combined with LED street lights has become a new design. However, Changhui’s experts pointed out that under the constraints of cost and wind resistance design, the application of LED street lights combined with solar energy design is limited. Mainly auxiliary lighting.

Since both solar and LED light sources use direct current, compared with AC household light sources, the combination of solar and LED light sources will not be affected by current conversion and affect conversion efficiency.

At present, due to the high cost of solar panels, and the large area of u200bu200bsolar panels will cause wind resistance, the most suitable ratio of LED to solar wattage is 1:4, and solar street lights should be used as auxiliary or secondary roads. the Lord. The emergence of solar LED street lights is suitable for areas with high sunlight, such as cities with sufficient sunlight such as Taiwan, which can maintain solar panels for continuous lighting for 3-5 nights. Therefore, solar LED street lights will bring good development space for Taiwan and other regions in the future development.
