Generally, the street lights are on at night. There is sufficient light during the day, so it is not necessary to turn on the street lights. However, if the visibility is not high in bad weather, especially in cloudy and rainy days, the probability of traffic accidents will increase. What are the advantages and functions of solar street lights at this time?
1. Reserve energy
We know that under the control of the intelligent controller, the solar street light in the daytime absorbs the solar light and converts it into electric energy after being irradiated by the sun. During the day, the solar cell panel charges the storage battery, and at night, the storage battery provides power to the LED light source to realize the lighting function.
The solar street light can fully charge the storage battery in sunny days, and if capacity is sufficient in rainy days, the power can be released. Therefore, the capacity of the battery is required to meet the number of days of normal lighting in rainy days. The solar lamp manufacturer provides different types of solar lights, such as competitive solar lamp cost，and has the most professional sales team, which will carry out strict configuration design according to the needs of customers, and also according to different places. It is recommended that the customer should guarantee the number of rainy days to ensure that the solar street light can be illuminated normally in rainy days.
2. Environmental protection, energy saving and low power consumption
Solar street lights are suitable for national roads, provincial roads, expressways, urban streets and other places. Solar street lights have the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency and long service life. Therefore, solar street lights will become the best choice for energy-saving transformation.
3. High illumination efficiency
Solar street lights are stronger than high-pressure sodium lamps. The color rendering performance of solar street lamps is obviously much higher than that of high-pressure sodium lamps. The color rendering index of high-pressure sodium lamps is only about 23, while the color rendering index of solar street lamps reaches more than 75. On average, the illuminance of LED street lamps can be reduced by more than 20% than that of high-pressure sodium lamps.
4. Slow light decay
The light attenuation of solar street lights will be relatively small, so the light attenuation in a year is less than 3%, which can still meet the road requirements after 10 years of use, while the light attenuation of high-pressure sodium lamps is generally large, which has dropped to more than 30% in about a year. Therefore, solar lamp manufacturers can achieve lower power than high-pressure sodium lamps in design.
5. Wide application range
Solar street lights can be used in any scene, including Decorative Solar Street Lights, Mini Solar Street Lights used in courtyards, parks and lawns, Integrated Solar Street Lights and Solar Landscape Lamps, etc.
