What are the characteristics of LED street lights The difference between LED street lights and ordinary street lights
With the rapid development of science and technology, as a kind of green lighting, the trend of replacing traditional lighting technology with LED street lamps is unstoppable. Many people do not particularly understand LED street lamps for indoor lighting. What are the characteristics of LED street lamps? What are the differences between LED street lights and ordinary street lights? Let's follow the editor of Jiu BENWEI LIGHTING to get to know it, I hope it will be helpful to everyone.
LED street light
What are the characteristics of LED street lights:
1. The characteristics of the LED street lamp itself: the one-way light, no light diffusion, to ensure the 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, and further improves the light efficiency to achieve the purpose of energy saving.
3. The light source efficiency of LED has reached 90-110lm/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 increases with the increase of power. Therefore, the overall light Effective LED street lights are stronger than high-pressure sodium lights.
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, the same brightness can be achieved. The average illuminance of LED street lamps can be It is more than 20[%] lower than that of high-pressure sodium lamps.
5. The light decay of LED street lights is small, less than 3% a year, and it can still meet the road use illuminance requirements after 10 years of use, while high-pressure sodium lights have a big decay, which has dropped by more than 30% in about a year. Therefore, LED street lights are in The power design can be lower than that of high-pressure sodium lamps.
6. The LED street lamp has an automatic control energy-saving device, which can achieve the greatest possible reduction in power and save energy under the condition of meeting the lighting requirements at different times.
7. LED is a low-voltage device. The voltage to drive a single LED is a safe voltage. The power of a single LED in the series is 1 watt, so it is a safer power supply than using high-voltage, especially suitable for public places.
8. Each unit LED chip has only a small volume, so it can be prepared into various shapes of devices, and is suitable for variable environments.
9. Long 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 cannot be guaranteed.
10. High light efficiency: Using chips ≥100LM, it can save energy by more than 75% compared with traditional high-pressure sodium lamps.
11. Easy installation: no need to add buried cables, no rectifiers, etc., directly install the lamp head of the street lamp on the lamp pole or nest the light source into the original lamp shell.
12. 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 in summer is insufficient.
13. Reliable quality: All circuit power supplies use high-quality components, and each LED has individual overcurrent protection, so there is no need to worry about damage.
14. Uniform light color: No lens is added, and the uniform light color is not sacrificed to increase the brightness, so as to ensure the uniform light color without aperture.
LED street light
The above is a detailed introduction about the characteristics of LED street lights. I believe that after the above introduction, everyone will have a better understanding and understanding of LED street lights. Of course, many people questioned the LED street lights. What's the difference? Let's take a look at the following introduction:
The difference between LED street lights and ordinary street lights:
1. Electricity fee comparison:
The electricity bills generated by using 60W LED street lights in a year are only 20% of the electricity bills generated by using 250W ordinary high pressure sodium street lights in a year, which greatly saves electricity costs. It is an ideal energy-saving and consumption-reducing product, and it also conforms to the trend of building a conservation-oriented society. .
2. Comparison of laying costs:
The power of LED street lights is 1/4 of that of ordinary high-pressure sodium street lights, and the cross-sectional area required for laying copper cables is only 1/3 of that of ordinary street lights, which saves a lot of laying costs.
3. Illumination comparison:
The use of LED60W street lights can reach the illuminance of 250W high-pressure sodium lamps, which greatly reduces the use power; LED street lights can be combined with wind and solar energy because of their low power, and can be used on urban secondary roads.
4. Use temperature comparison:
Compared with ordinary street lights, LED street lights generate lower temperature during use, and will not produce high temperatures during continuous use, and will not turn black or burn black lampshades.
5. Safety performance comparison:
At present, cold cathode lamps and induction lamps on the market use high-voltage point poles to excite X-ray illumination, which contains harmful metals such as mercury, and harmful rays. In contrast, LED street lamps are safe and low-voltage products. In the process, potential safety hazards are greatly reduced.
6. Environmental protection performance comparison:
Ordinary street lamps contain harmful metals, and the spectrum contains harmful rays. Compared with LED street lamps, the spectrum is pure, without infrared and ultraviolet rays, no radiation, no light pollution, and no harmful metals, and the waste can be recycled, which is typical Green environmental protection lighting products.
7. Comparison of service life and quality:
The average service life of ordinary street lights is 12,000 hours. The replacement of street lights is not only costly, but also affects traffic. It is especially inconvenient to construct in tunnels and other places. The average lifespan of LED street lights is 100,000 hours. Based on 10 hours of daily use, the service life is as long as ten years. Above, once and for all, besides, LED street lamp has good water resistance, impact resistance and shock resistance, and the quality is stable. It is a maintenance-free product during the warranty period.
