【Anhui led street light】 Simple description of led street light

The LED light source adopts low-voltage DC power supply, high-efficiency white light synthesized by GaN-based power type blue LED and yellow. It has the unique advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response speed, and high color rendering index. The outer cover can be made with high temperature resistance up to 135 degrees and low temperature resistance up to -45 degrees.

Advantage

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 required lighting area, which 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 20% lower than high pressure sodium lamp,

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 is decayed, which has dropped by more than 30% in about a year. Therefore, the design of the LED street light uses power 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.

8. High luminous efficiency: the use of chips ≥100LM 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 the passive heat dissipation method is adopted, and the heat dissipation guarantee is sufficient in summer.

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 will not cause harm to the environment when scrapped.

Low maintenance cost: Compared with traditional street lamps, the maintenance cost of LED street lamps is extremely low. After comparison, the total input cost can be recovered in less than 6 years .

Replace high-pressure sodium lamp can save more than 60%
