LED street light is the trend, what are its characteristics and advantages?
LED street lights have gradually entered people's field of vision with the advantages of directional light emission, low power consumption, good driving characteristics, fast response speed, high shock resistance, long service life, and green environmental protection, and have become the new generation that has the advantage of replacing traditional light sources in the world. Energy-saving light source, therefore, LED street lights will become the best choice for energy-saving renovation of road lighting. LED street lamps are semiconductor lighting lamps, which use light-emitting diodes as light sources. Because they are solid-state cold light sources, they are environmentally friendly, pollution-free, low power consumption, high luminous efficiency, and long life.
LED street light features
The difference between Yaorong Lighting LED street lights and conventional high-pressure sodium street lights is that high-power LED lights have the unique advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response speed, and high color rendering index, which can be widely used in urban road lighting. The outer cover can be made of PC tube, which can withstand high temperature up to 80 degrees and low temperature resistance up to -45 degrees.
Advantages of LED street lights
1. The characteristics of the LED street light itself--unidirectional light, no light diffusion, to ensure 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, further improving the lighting efficiency and achieving the purpose of energy saving.
3. The light source efficiency of LED road has reached 130-150lm/W at present, 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.
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, to achieve the same brightness, 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% in one year, and it still meets the requirements of road use illuminance after 10 years of use, while the high pressure sodium light decay is large, and it has dropped by more than 30% in about a year. Therefore, LED street lights are in Longer service life.
