Why led street lights become fashionable

Jan 04, 2020

LED street lights are now fashionable in the street light industry, mainly because it has the following characteristics:

1. The characteristics of LED street lights-one-way light, no light diffusion, to ensure lighting efficiency.

2. The LED street light has a unique secondary optical design, which illuminates the light of the LED street light to the area to be illuminated, further improving the lighting efficiency to achieve the purpose of energy saving.

3. The light source efficiency of LED has reached 110-130lm / W, and there is still a lot of room for development. The theoretical value is 250lm / W. The luminous efficiency of high-pressure sodium lamps only increases with the increase of power. Therefore, the overall light-efficiency LED street lights are stronger than high-pressure sodium 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, while the color rendering index of LED street lamps reaches above 75. From the perspective of visual psychology, the same brightness can be achieved. The average brightness of LED street lamps can be Reduced by more than 20% than high pressure sodium lamps.

5. The light decay of LED street lights is small, less than 3% in one year, and it still meets the road use illumination requirements for 10 years. The high-pressure sodium light decays, and it has fallen by more than 30% in one year. Therefore, LED street lights The design of the power used can be lower than that of HPS.

6. LED street lights have automatic control energy-saving devices, can achieve the maximum possible reduction in power in the case of meeting different lighting requirements, saving energy. Spark intelligent LED street light can realize user-friendly functions such as computer dimming, time segment control, light control, temperature control, remote control, automatic inspection and so on.

7. LED is a low-voltage device. The voltage for driving a single LED is a safe voltage. The power of a single LED in a series of products is 1 watt, so it is a safer power supply than using a high-voltage power supply, which is especially suitable for public places.

8. Each small piece of LED street light has only a small volume, so it can be prepared into various shapes of devices, and is suitable for variable environments.

9.long life: can be used for more than 50,000 hours, providing three years of quality assurance. The disadvantage is that the life of the power supply is not guaranteed.

10.high light efficiency: using chips ≥ 100LM, can save more than 75% of energy compared to traditional high-pressure sodium lamps.

11. Easy installation: No need to bury cables or rectifiers, directly install the lamp cap of the street lamp on the pole or nest the light source into the original lamp housing.

12. Excellent heat dissipation control: In summer, the temperature is controlled below 45 degrees, and passive cooling is adopted, so the heat dissipation guarantee in summer is insufficient.

13. Reliable quality: All circuit power supplies use high-quality components, and each LED has separate overcurrent protection, so there is no need to worry about damage.

14. Uniform light color: No lens is added, and uniform light color is not sacrificed to improve brightness, thereby ensuring uniform light color without aperture.

15.LED does not contain harmful metal mercury, unlike high-pressure sodium lamps or metal halide lamps when it is scrapped to cause harm to the environment.
