The neon lights of the city are flashing. Walking on the urban streets, at first glance, the lights are off, but if you look closely, they are all LED lighting, even the street lights. I want to find an incandescent lamp. , but still only regret. Why have even the street lights on the roadside been replaced by LED street lights? Where has the shadow of the incandescent lamp gone?
Having said this, I have to sigh at the rapid changes in science and technology. The development of science and technology has driven the development of lamps and lanterns, which are updated generation after generation. If changes cannot be made and the trend of development is followed, incandescent lamps will serve as a warning. The roadside lamps have become LED street lights instead of incandescent lamps, which means that incandescent lamps have been eliminated by LED street lamps.
To summarize, there are four major advantages: 1. The light source power of LED street lights has now reached 110-130lm/W, and its development space is still large, and it can theoretically reach 250lm/W. The luminous power 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 to achieve the purpose of energy saving. 2. The light color rendering of LED street lamps is much higher than that of high-pressure sodium lamps. Generally, the color rendering index of high-pressure sodium lamps is only about 23, but the color rendering index of LED street lamps can reach more than 75. In other words, to achieve the same brightness, the color rendering index of LED street lamps Uniform illumination can be reduced by more than 20% compared to high-pressure sodium lamps. 3. The attenuation of LED street lights is very small. Data shows that its light attenuation in one year is less than 3. When designing and using power for LED street lights, it can be much lower than that of high-pressure sodium lamps. 4. LED street lights have a long service life. Compared with traditional high-pressure sodium lamps, they can save a lot of costs. Moreover, they have unique automatic control energy-saving equipment to save electricity. More importantly, they do not contain harmful metal mercury and will not be used when scrapped. It cannot cause any damage to the environment. ?
