Problems solved by technology

[0003]At present, the heat dissipation equipment for street lamps in daily life is mainly metal micro-grids with high specific surface area. By increasing the surface area of ​​metal micro-grids, the heat dissipation speed is increased, but the heat dissipation method is single and the heat dissipation efficiency is low. Relatively low, can not greatly increase the life of the street lamp

Abstract

The invention discloses a multi-stage infrared radiation street lamp shade. The multi-stage infrared radiation street lamp shade is composed of a metal shell, a reflecting layer coating coated on theinner wall of the metal shell and an infrared radiation coating coated on the outer side of the metal shell. The reflective layer coating takes a polyaluminosilicate layer as a bottom reflective layerand takes a silicon carbide layer as an outer radiation layer; the infrared radiation coating takes a silicon carbide layer as a bottom layer and an insulating layer, and a graphitizable polymer layer as an upper layer and a rivet fixing layer, and spherical graphene penetrates through the two-layer structure. The multi-stage infrared radiation street lamp shade utilizes the wrinkled structure ofspherical graphene, and realizes multi-stage infrared rapid heat dissipation under the coacervation and combination action of macromolecules and the cooperation of small-molecule high-radiation inorganic particles. Meanwhile, the reflecting coating on the inner wall has the effects of high radiation and high reflection, and the heat transfer to the lamp shade is reduced. The two coatings are combined, so that the temperature of the lamp shade is greatly reduced, the service life of a street lamp is prolonged, and the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of infrared heat dissipation, and in particular relates to a multi-stage infrared heat dissipation street lamp lampshade. Background technique [0002] With the development of society, human beings are more and more dependent on energy, but with the gradual consumption of fossil energy, the cost of energy is getting higher and higher. Therefore, it is imminent to use energy more efficiently in human life and production activities. At the same time, people have higher and higher requirements for the quality of production and life. Under the same cooling purpose, energy saving has become the first choice. [0003] At present, the heat dissipation equipment for street lamps in daily life is mainly a metal micro-grid with a high specific surface area. The heat dissipation speed is increased by increasing the surface area of ​​the metal micro-grid, but the heat dissipation method is single, and the heat dissipati...
