Talking about the development advantages of led street lights
With the demands of modern development, LED street lamps, such as energy-saving and emission-reducing products, are becoming more and more popular among consumers. Below we briefly introduce the competitive advantages of LED street lamps in the street lamp industry:
1Environmental protection:
LED does not contain heavy metals such as hazardous metals hg, and does not produce pollutants. Unlike high-pressure sodium lamps or metal halide lamps, they are harmful to the environment when they are scrapped.
2Long life:
The light decay of LED street lights is small, less than 3% in a year, and it can still meet the road use illuminance requirements after 10 years of use, while high-pressure sodium lamps have a large decay, which has dropped by more than 30% in about a year. Therefore, LED street lights are using power The design can be lower than the high pressure sodium lamp, but the life is longer.
3 High safety factor:
LED street lights are low-voltage products. Of course, this is for solar LED street lights. 12V is enough, and the voltage of the mains LED street lights is still 220V.
4 Energy saving:
The light source efficiency of LED has reached 110-130lm/W, and there is still a lot of room for development, with a theoretical value of 250lm/W. The luminous efficiency of high-pressure sodium lamps increases with the increase in power. Therefore, the overall luminous efficiency of LED street lamps is stronger than that of high-pressure sodium lamps; using high-power LED light sources with high-efficiency power supplies, the actual lighting effect has been tested compared to the current high-pressure sodium lamps used on the road. Energy saving is more than 60%, and there is still a lot of room for technological progress. With the rapid improvement of LED efficiency, LED street lamps have shown great potential in energy saving.
5 Low maintenance cost:
According to the current technical level and test results, the high-power LED light source can be used normally for 10 years without replacement, while the traditional high-pressure sodium lamp needs to be replaced once a year and a half on average. The use of LED light sources can greatly reduce maintenance costs.
6 color temperature options:
LED can meet the color temperature requirements of different occasions, and indoor and outdoor color temperature requirements are different. Home lighting is not the same as commercial lighting. In addition, some stores need alternative white LED lights to make their products more fashionable and exquisite, and to satisfy shoppers’ appetites in terms of color. The color temperature of the high-pressure sodium lamp is too low, making people depressed and hypnotic. The yellow light in summer may give people a feeling of heat.
7 will not flicker:
LED street lights can respond quickly, shorten the lighting time, and will not occur stroboscopic, which is suitable for protecting the eyes.
8 Good color rendering:
The light color rendering of LED street lamps is much higher than that of high pressure sodium lamps. The color rendering index of LEDs is high (75~80). The color rendering index of high pressure sodium lamps is only about 23. From the perspective of visual psychology, the same brightness can be achieved. It is more than 20% lower than high pressure sodium lamp. And the road looks brighter, feels more comfortable, and the driver feels safer.
