Abstract

The invention relates to a nanometer self-cleaning film, a preparation method thereof and a lamp. The technical problems of large thickness of protective films, waste of materials and complicated coating processes of existing self-cleaning lamps are mainly solved. According to the technical scheme, the nanometer self-cleaning film is composed of anA layer film and a B layer film, and the A layer film and the B layer filmare prepared from photocatalysis materials containing nanoscale TiO2 and SiO2. The preparation method includes the following steps: (1) the A layer film is prepared; and (2) the B layer film is prepared. The lamp prepared from the nanometer self-cleaning film comprises a light source, an aluminum foil shell, and an acrylic plate, and further comprises a reflection point, alampshade and the nanometer self-cleaning film composed of the A layer film and the B layer film arranged on the acrylic plate, the A layer film is arranged on the outer surface of the lampshade, andthe B layer film is arranged on the A layer film to form the nanometer self-cleaning film.

Description

technical field [0001] The invention relates to a nano self-cleaning film, a preparation method and a lamp. Background technique [0002] The heat dissipation of the lamp and its driver circuit is very large. If the heat is not released in time, it will cause damage to the power supply, and a sharp decline in the luminosity and life of the lamp. Therefore, heat dissipation is a short board that restricts the performance of the lamp. Due to the special working environment of the tunnel lamp, the air in the tunnel is turbid and contains a lot of dust and particles. The heat sink of the tunnel lamp is very easy to reduce the heat dissipation performance due to the adsorption of a large amount of dust, which cannot meet the heat dissipation requirements of the lamp. In addition, the installation height of the tunnel light is extremely high, and maintenance is difficult. It is difficult for maintenance personnel to inspect and remove the dust accumulated on the radiator of the tu...
