What Are the Features of LED Road Light Products?

LED road lights are different from conventional road lights in that the LED light source uses low-voltage DC power and is composed of high-efficiency white light synthesized from GaN power blue light LED and yellow. They have the advantages of high efficiency, safety, energy saving, environmental friendliness, long lifespan, quick response, and high color rendering index, and can be widely used in roads. The shell can be made of materials that can withstand high temperatures up to 135℃ and low temperatures down to -45℃.

  • The inherent characteristic of LED road lights—unidirectional light, without diffused light, ensures high lighting efficiency.

  • LED road lights use innovative secondary optical design to direct the light to the desired illuminated area, further enhancing lighting efficiency for energy savings.

  • LED road lights have reached 160lm/W, while the luminous efficiency of high-pressure sodium lamps increases with power, so the overall efficiency of LED road lights is stronger than that of high-pressure sodium lamps (this overall efficiency is theoretical, in reality, the luminous efficiency of high-pressure sodium lamps above 250W is higher than that of LED lamps).

  • The color rendering of LED road lights is 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 LED road lights can reach over 75. From a psychological perspective, at the same brightness level, the illuminance of LED road lights can be reduced by more than 20% compared to high-pressure sodium lamps.

  • LED road lights have minimal light decay, with less than 3% decay per year, and meet road requirements even after 10 years of use, while high-pressure sodium lamps have much higher decay rates with over 30% decay in the first year, so LED road lights can be designed with a lower power consumption than high-pressure sodium lamps.

  • LED road lights have automatic energy-saving devices that can minimize power consumption while meeting different lighting requirements in various periods. They can adjust the light through computer dimming, time segmentation control, light control, temperature control, automatic inspection, and other humanized functions.

  • LED road lights have a long lifespan, with a lifespan of over 50,000 hours and a three-year quality guarantee. However, the life of the power supply is not guaranteed.

  • LED road lights have high efficiency, with energy savings of 75% or more relative to traditional high-pressure sodium lamps.

  • LED road lights are easy to install, with no need to add buried cables or rectifiers. They can be directly connected to the lamp pole or embedded in the original lamp shell.

  • The heat dissipation of LED road lights is excellent, with summer temperatures controlled below 45℃ using passive heat dissipation methods. However, summer heat radiation protection is insufficient.

  • LED road lights are reliable, with high-quality components used for the circuit and power supply, and each LED has individual overcurrent protection, so there is no need to worry about damage.

  • The light color of LED road lights is uniform, with no lens added to sacrifice uniform color for increased brightness, ensuring no halo and uniform light color.

  • LED road lights do not contain harmful mercury and will not cause harm to the environment when scrapped.

Overall, the energy savings achieved by LED road lights are significant, with a 60% or more reduction in electricity use compared to high-pressure sodium lamps.

  • The maintenance cost of LED road lights is low, with an extremely low maintenance cost compared to traditional road lights, and the investment cost can be recovered in less than six years.
