1. Its own characteristics-the unidirectional light, no diffusion of light, to ensure the efficiency of lighting.
2. The LED street lamp has a unique secondary optical design, which illuminates the light of the LED street lamp to the area required for illumination, and further improves the lighting efficiency to achieve the purpose of energy saving.
3. The LED has reached 110-130lm / 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 only with the increase of power. Therefore, the overall light efficiency of LED street lamps is stronger than that of high-pressure sodium lamps; (This overall light effect is theoretical, in fact, the light efficiency of high-pressure sodium lamps above 250W is higher than that of LED lamps. ).
4. The 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, and the color rendering index of LED street lamps reaches more than 75. From the perspective of visual psychology, to achieve the same brightness, the average illumination of LED street lamps can be More than 20% lower than high-pressure sodium lamps.
5. The light decay is small, the light decay is less than 3% in one year, and it still meets the road requirements after 10 years of use, and the high-pressure sodium lamp decay, which has dropped by more than 30% in about one year. Can be lower than high pressure sodium lamps.
6. The LED street lamp has an automatic control energy-saving device, which can achieve the maximum possible power reduction and energy saving when meeting the lighting requirements of different periods. It can realize humanized functions such as computer dimming, time control, light control, temperature control, and automatic inspection.
7. Long lifespan: it can be used for more than 50,000 hours and provide a three-year quality guarantee. The disadvantage is that the life of the power supply cannot be guaranteed.
8. High luminous efficiency: the use of chips ¡İ100LM or above can save energy by more than 75% compared with traditional high-pressure sodium lamps.
9. Easy installation: no need to bury cables or rectifiers, etc., directly install the lamp pole or nest the light source in the original lamp housing.
10. Excellent heat dissipation control: the temperature in summer is controlled below 45 degrees, and passive heat dissipation is adopted, and the heat dissipation guarantee in summer is insufficient.
11. Reliable quality: The circuit power supply uses high-quality components, and each LED has a separate over-current protection, without worrying about damage.
12. Uniform light color: no lens is added, 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 causes harm to the environment when scrapped.
