What are the problems with energy-saving lighting of led street lights?
In recent years, LED has grown rapidly, and many cities are vigorously promoting LED street lamps and transforming traditional street lamps into energy-saving LED street lamps. Although the market prospects of LED street lighting are quite unsightly, there are still some problems with LED street lighting. If LED street lighting wants to truly occupy the market, it may need to solve the problem of its energy-saving lighting. Masters know that led street lights have very good energy-saving effects, but they cannot be generalized. The extent of its energy saving depends mainly on its 'rivals' and also on the mode of use. The reason why LED street lights can be used is that their dimming performance is better than traditional lights, so they can be used as an alternative light source. The biggest energy-saving link of road lighting is dimming. At present, the dimming of traditional lights can only be adjusted by half, and LED street lights can be adjusted to 5%-10%. This is also one aspect of LED street lights superior to traditional street lights. But dimming should be based on changes in traffic flow at different times. The final energy saving of led road lights depends on the size of the traffic flow. Combining the single-light control dimming of street lights with traffic flow is advanced in China, and it is also the emergence of the advanced nature of led street lights.
