Advantages of using LED street lighting on roads
At present, more and more lighting fixtures are beginning to be replaced with LED fixtures, and LED street lights are no exception. As we all know, street lights consume a lot of power, so the lighting transformation of LED street lights is very important, which can greatly save power, then LED What are the advantages of street lights?
1. Its own characteristics - unidirectional light, no light diffusion, to ensure lighting 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 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 80. 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.
4. 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 computer dimming, time-segment control, light control, temperature control, automatic inspection and other humanized functions.
5. Long service life: more than 50,000 hours, providing five-year quality assurance.
6. Easy installation: no need to bury cables, no rectifiers, etc., directly connect to the lamp pole or nest the light source into the original lamp shell.
7. Reliable quality: 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.
8. Uniform light color: no lens is added, and uniform light color is not sacrificed to improve brightness, so as to ensure uniform light color without aperture.
9. LED does not contain harmful metal mercury, which will not cause harm to the environment when it is scrapped.
Combining the above principles, the energy-saving effect is remarkable, and the power-saving rate of replacing high-pressure sodium lamps is more than 60%. Low maintenance cost: 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.
