A breathable environmentally friendly solar street light

technical field

The utility model relates to the field of lighting fixtures, in particular to a breathing environment-friendly solar street lamp with an air purification function.

Background technique

As the infrastructure of the city, street lights are distributed in every corner of the city, and the number gradually increases with the development of the city. For example, first-tier cities such as Beijing have more than 300,000 lamps, second-tier cities such as Changchun have more than 100,000 lamps, and some small and medium-sized cities have more than 10,000 lamps. In addition to the lighting and beautifying functions of these street lamps, if they can have air purification functions, they will definitely improve the urban air quality. However, most of the existing street lamps only have lighting function. Some patents have proposed some street lamps with air purification function. The environmental protection street lamps mentioned in the Chinese patent 200710156263.1 document and the Chinese patent 200620131207.3 document rely on titanium dioxide photocatalyst coating. Hydrocarbons are decomposed into carbon dioxide and water, and the titanium dioxide photocatalyst coating requires ultraviolet light to achieve the air purification function described in the patent. Effective treatment of hydrocarbons in the air, and this patented technology does not have the purification function for the main pollutants of sulfur dioxide and nitrogen dioxide widely present in the air. The Chinese patent 200420045530.X document mentions an environment-friendly street lamp. The environmental protection function of the street lamp designed in this patent document mainly relies on the existing ozone generator or negative ion purifier to realize, but the ozone generator and negative ion purifier can purify air pollutants. Functionality is limited. Then, adopting certain technologies to enable street lamps widely distributed in cities to have the breathing function similar to trees, inhale harmful pollutants and exhale oxygen, will greatly improve urban air quality.
