In the process of modern urbanization, road lighting is not only an important part of urban infrastructure, but also a key factor in improving the city's image and ensuring traffic safety. In recent years, with the continuous advancement of science and technology, LED street lights have gradually become the mainstream choice in the field of road lighting with their excellent performance and significant advantages.
1. What are the advantages of LED street lights?
High efficiency and energy saving
LED street lights use light-emitting diodes as light sources and have extremely high luminous efficiency. Its luminous efficiency has reached 110-130lm/W, and there is still a lot of room for improvement, with a theoretical value of up to 360lm/W. Compared with traditional high-pressure sodium lamps, LED street lights can save more than 75% of energy at the same brightness. In addition, LED street lights also have automatic control energy-saving devices, which can automatically adjust the power according to the lighting needs of different time periods to further reduce energy consumption.
Long life and low maintenance cost
The service life of LED street lights is more than 50,000 hours, providing a quality guarantee of up to three years. In contrast, the life of traditional high-pressure sodium lamps is shorter, and the light decay can reach more than 30% in about a year. The long life of LED street lights not only reduces the frequency of replacement, but also reduces maintenance costs, and the entire investment cost can be recovered in less than 6 years.
Environmentally friendly and pollution-free
LED street lights do not contain harmful metal mercury and will not cause harm to the environment when scrapped. Its light source is a solid-state cold light source, which is environmentally friendly and pollution-free, and meets the needs of modern society for green lighting.
Excellent color rendering and light efficiency
The color rendering index of LED street lamps is as high as 75 or above, which is much higher than the 23 of high-pressure sodium lamps. This means that under the illumination of LED street lamps, the color of objects is more realistic, which can effectively improve the visibility and safety of drivers and pedestrians. At the same time, the light decay of LED street lamps is small, and the light decay in one year is less than 3%. It can still meet the road lighting requirements after 10 years of use.
Flexible secondary optical design
LED street lights have a unique secondary optical design that can accurately illuminate the area where lighting is required, further improving the lighting efficiency. This design not only reduces the waste of light, but also can be customized according to different road conditions and lighting requirements to achieve a more reasonable light distribution.
LED street lights are gradually replacing traditional street lamps and becoming the first choice for road lighting due to their advantages such as high efficiency and energy saving, long life, environmental protection and pollution-free, and excellent color rendering. It not only improves the lighting quality of the city, but also makes important contributions to environmental protection and sustainable development. With the continuous advancement of technology and the continuous expansion of the market, LED street lamps will play a more important role in future urban lighting.
