What is the future development prospect of solar street light

This year, China has stepped up its prevention and control of smog. Without a good environment, how can people live with peace of mind? China has also increased its investment in greening. Haze is basically in winter, which has a certain relationship with tree leaves. At this time, if street lamps that can eliminate dust and smog are born, the order quantity will increase in an all-round way. The principle is basically very simple. There is an air outlet on the top of the light pole, and an air outlet at the lower end. The wind enters from the bottom and exits from the top. A filter device is added in the middle, which is to eliminate dust and haze. The whole process, do not A little bit of electricity can be done as long as the light pole is reconfigured. The most important issue is that, if removed, the dust in the filter unit. This should be combined with greening, that is, above the filter device, there is a water cleaning port, which is flushed with water once a month, and the water flows into the green belt. This serves the purpose of greening the water supply. But it would be great if there was a device that didn't flush with water. If the street lights around us also have the function of eliminating dust and smog, would you choose? Now is not the era of price competition, but the era of innovation and practicality? Really serve the people.
