At present, the global environment is deteriorating day by day, and all countries are developing clean energy. With the rapid growth of the national economy, the contradiction between energy supply and demand in my country has become increasingly prominent, and there is a serious shortage of power supply. Energy saving is an urgent problem to be solved. Therefore, the development of new high-efficiency, energy-saving, long-life, high-color rendering index, and environmentally friendly street lamps is of great significance for urban lighting energy conservation.
Road lighting is an important part of urban lighting. Traditional street lamps often use high-pressure sodium lamps to emit light at 360 degrees. The disadvantage of large light loss results in a huge waste of energy. However, LED street lamps have a significant energy-saving effect. Replacing traditional high-pressure sodium lamps can save more than 60% of electricity. .
Road lighting is closely related to people's production and life. With the acceleration of my country's urbanization process, LED street lights are gradually developing with the advantages of directional lighting, low power consumption, good driving characteristics, fast response speed, high seismic resistance, long service life, and green environmental protection. Into people's field of vision, become the world's most new generation of energy-saving light sources with the advantages of replacing traditional light sources, therefore, LED street lights will become the best choice for energy-saving renovation of road lighting.
Advantages of LED street lights:
1. The characteristics of the LED street light itself - unidirectional light, no light diffusion, to ensure light efficiency.
2. The LED street light has a unique secondary optical design, which irradiates the light of the LED street light to the area that needs to be illuminated, further improving the lighting efficiency and achieving the purpose of energy saving.
3. The LED has reached 100-130Lm/W, and there is still a lot of room for development, with a theoretical value of 360Lm/W. The luminous efficiency of high-pressure sodium lamps increases with the increase of power. Therefore, the overall luminous efficiency of LED street lamps is stronger than that of high-pressure sodium lamps.
4. The light color rendering of LED street lamps 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 street lamps is above 75. From the perspective of visual psychology, to achieve the same brightness, the average illuminance of LED street lamps can be It is more than 20% lower than that of high pressure sodium lamps.
5. The LED street light declines less than 3% in one year, and it still meets the road requirements after 10 years of use, while the high-pressure sodium light declines more than 30% in about a year. Therefore, the design of LED street light power is comparable High pressure sodium lamps are low.
6. The LED street light has an automatic control energy-saving device, which can achieve the maximum possible power reduction and save energy under the condition of meeting the lighting requirements of different periods. It can realize user-friendly functions such as computer dimming, time-segment control, light control, and temperature control.
7. The LED street light has a long service life: it can be used for more than 50,000 hours and provides a three-year quality guarantee. The disadvantage is that the life of the power supply is not guaranteed.
8. High efficiency of LED street light: using chips of ≥100LM or more can save energy by more than 75% compared to traditional high-pressure sodium lamps.
9. LED street lights are easy to install: no need to bury cables, no rectifiers, etc., directly connect to the lamp pole or nest the light source into the original lamp housing.
10. Excellent heat dissipation control of LED street lights: the temperature in summer is controlled below 45 degrees, and passive heat dissipation is adopted.
11. The quality of LED street lights is reliable: the circuit power supply adopts high-quality components, and each LED has its own over-current protection, so there is no need to worry about damage.
12. Uniform color of LED street light: no lens is added, and uniform light color is not sacrificed to improve brightness, so as to ensure uniform light color without aperture.
13. LED does not contain harmful metal mercury, which will cause harm to the environment when it is scrapped.
14. Low maintenance cost of LED street lights: Compared with traditional street lights, the maintenance cost of LED street lights is extremely low. After comparison, all investment costs can be recovered in less than 6 years.
To sum up the above, LED street lamps have a significant energy-saving effect, and can save more than 60% of electricity instead of traditional high-pressure sodium street lamps.
