Solar LED street lights are very popular in the market because they are more energy-efficient and environmentally friendly compared to traditional street lights, attracting countless customers. Below, let’s explore some characteristics of solar street lights, which are also the reasons for their widespread appeal.
The color rendering index of solar LED street lights is significantly higher than that of high-pressure sodium lamps. The color rendering index of high-pressure sodium lamps is around 23, while solar LED street lights reach an index above 75. From a visual psychology perspective, considering equal brightness, the illumination of solar street lights can be more even and 20% less than that of high-pressure sodium lamps, ensuring efficient lighting without dispersion. Moreover, it operates on a safer power supply of 250lm/W. The light efficiency of high-pressure sodium lamps increases only with higher power, which means the overall light efficiency of solar street lights surpasses that of high-pressure sodium lamps. For high-power solar street lights, the light efficiency exceeds that of a 250W high-pressure sodium lamp, directing light precisely to the areas that require illumination and further enhancing lighting efficiency, making them especially suitable for public spaces.
Solar street lights are equipped with active control energy-saving devices that keep summer temperatures below 45 degrees and utilize passive heat dissipation methods. During hot summers, solar street lights can autonomously dissipate heat. They can achieve time-based control, light control, temperature control, remote control, and automatic inspections, making them more user-friendly and safer than using a high-voltage electric supply.
In summary, the energy-saving effect of solar LED street lights is remarkable, as they can save over 60% in electricity compared to high-pressure sodium lamps. In contrast to traditional street lights, the maintenance costs of solar street lights are extremely low, with a payback period of less than six years for the total investment. This is why solar street lights are so well-received by everyone.
