Good places for LED street lights (1)

The difference between LED street lights and general street lights is that the LED street light source uses a high-efficiency white light composed of blue LED and yellow, and low-voltage DC power supply. It has high efficiency, safety, energy saving, environmental protection, long life, fast response speed, With a series of unique advantages such as high color rendering index, it can be widely used on roads. In addition, the process of making its outer cover can withstand high temperatures up to 135 degrees and low temperature resistance to minus 45 degrees. Advantages: 1. LED street light characteristics-the light is one-way, and there is no diffuse effect of light, and the efficiency of light is guaranteed. 2. The unique design of the secondary optics-LED street lamp, the lighting area irradiated by the LED street lamp light is a step forward in improving the efficiency of light, achieving the purpose of energy saving. 3. Compared with the high-pressure sodium lamp, the color rendering of LED street lamps is much higher than that of high-pressure sodium lamps. We know that the color rendering index of high-pressure sodium lamps is only 23, but the color rendering index of LED street lamps is above 75. From a visual psychological point of view, that is to say, when reaching the same brightness, the average illuminance of LED street lights can be as much as 20% less than that of high-pressure sodium lamps. 4. The light decay is very small. The luminous decay of LED street lamps is less than 3% throughout the year. Even after 10 years of work, it can still meet the road lighting requirements, while the high-pressure sodium lamp decay is very large, one year It can be reduced by more than 30%. Therefore, in the design of using power, LED street lamps can be said to be much lower than high-pressure sodium lamps. 5. The LED street lamp has an automatically controlled energy-saving device, which can reduce the power as much as possible under different lighting requirements at different time periods, and save energy very efficiently. Realize computer dimming, time period control, light control, temperature control, automatic inspection and other humanized functions. Based on the above, the energy-saving effect of LED street lamps is obvious. If high-pressure sodium lamps are replaced, it can save about 60% more electricity. Low maintenance cost: Compared with traditional street lights, the maintenance cost of LED street lights is super low. If you compare it, it can happen. As long as it takes less than six years, you can recover all the invested costs.
