LED street lights advertised as energy-saving and carbon-reducing, the tube can play a certain function, but many cities in the United States have found that because LEDs can not dissipate heat and melt snow, the lamps are easily covered by heavy snow and cannot be illuminated, resulting in an increase in traffic accidents, at least one person Killed.
The Midwestern United States suffered a rare blizzard last week, and many cities were snowy and killed at least 17 people. One of them was caused by a nighttime lighting device that failed to recognize the road conditions and caused a car accident.
In recent years, many states in the United States have considered the trend of funds and energy-saving and carbon reduction, and switched to LED street lamps with long power consumption and long life. However, LED lamps that achieve energy-saving effects because they do not dissipate heat are also troublesome because they do not dissipate heat.
Some states in the United States have found that LED lights do not dissipate heat. When the wind and snow are mixed, the street lights will be blocked by heavy snow because they cannot melt snow.
Although some areas are coated with waterproof materials outside the LED street lights, or installed with snow and snow shutters, the effect is limited. Many states in the blizzard, in addition to sending people to clean the road area snow, but also have to send people to clear the snow on the street lights.
