Eight advantages of LED street lights
Compared with traditional high pressure sodium lamps, LED street lamps have the following advantages:
1. 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 of 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. 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 lights have shown great potential in terms of energy saving.
2. 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), and 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. , The illuminance of LED street lamps can be reduced by more than 20% compared with high-pressure sodium lamps on average. And the road looks brighter, feels more comfortable, and the driver feels safer.
3. Long service life: The light decay of LED street lights is small, less than 3% in one year, and the illuminance requirements for road use are still met after 10 years of use. , LED street lamps can be designed to use lower power than high-pressure sodium lamps, but have a longer lifespan.
4. Green and environmental protection: LED does not contain harmful metals such as mercury and other heavy metals, and does not produce pollutants, unlike high-pressure sodium lamps or metal halide lamps that cause harm to the environment when they are scrapped.
5. Low maintenance cost: Based on the current technical level and test results, high-power LED light sources can be used for 10 years without replacement, while traditional high-pressure sodium lamps need to be replaced on average once a year and a half. The use of LED light sources can greatly reduce maintenance costs. .
6. Color temperature optional: LED can meet the needs of color temperature in different occasions. Indoor and outdoor color temperature requirements are different. Home lighting and commercial lighting are also different, and some stores need alternative LED white light to make their products more stylish and sophisticated. Satisfy the shopper's appetite from the color. The color temperature of high-pressure sodium lamps is too low, which can make people depressed and hypnotized, and the yellow light in summer may give people a feeling of heat.
7. High safety factor: LED street lights are low-voltage products. Of course, this is for solar LED street lights, 12V is enough, and the mains LED street lights are still 220V.
8. No stroboscopic: LED street lights can respond quickly, shorten the lighting time, and will not flicker, which is the most suitable for eye protection.
