Lamp cover for blue light filtering, sterilization and reflection resisting and manufacturing method thereof

Abstract

The invention discloses a lamp cover for blue light filtering, sterilization and reflection resisting and a manufacturing method thereof. The lamp cover comprises a substrate. A first film layer, a second film layer, a third film layer, a fourth film layer, a fifth film layer, a sixth film layer, a seventh film layer, an eighth film layer and a ninth film layer are successively arranged from inside to outside on the outer surface of the substrate. The first film layer, the fourth film layer and the sixth film layer are trititanium pentoxide layers. The thickness of each of the trititanium pentoxide layers is 10-100 nm. The second film layer, the fifth film layer and the seventh film layer are silicon dioxide layers. The thickness of each of the silicon dioxide layers is 50-100 nm. The third film layer is a metal layer of which the thickness is 5-20 n. The eighth film layer is a nano-silver layer of which the thickness is 5-20 nm. The ninth film layer is an acrylic acid layer of which the thickness is 5-15 nm. The manufacturing method comprises following steps of 1) cleaning the substrate; and 2) carrying out film coating on the outer surface of the substrate. The lamp cover is capable of effectively filtering harmful blue light and dazzling light, so reflection resisting performance can be improved and the lamp cover has a sterilization function.

Description

technical field [0001] The invention relates to the technical field of lampshades, in particular to a lampshade for filtering blue light for sterilization and anti-reflection and a manufacturing method thereof. Background technique [0002] With the progress of society and the development of science and technology, lighting equipment has widely entered people's work and life. As people use lighting equipment (such as lamps) for an increasing The damage to eyesight is getting more and more serious. [0003] Blue light is high-energy visible light with a wavelength of 400-500nm. Blue light can directly penetrate the cornea, eye lens, and reach the retina. The retinal pigment epithelial cells have a strong absorption effect on the light radiation in the blue light area, and the absorption of blue light radiation will cause the retinal pigment epithelial cells to shrink, which is also one of the main causes of macular degeneration; the higher the blue light radiation component ...

AI Technical Summary

Problems solved by technology

[0004] At present, it is mainly to set lampshades outside the lamps to concentrate light, prevent wind and rain, and solve the above problems, but the effect is not ideal. People are exposed to light for a long time, and their bodies are greatly affected.

In addition, in the cold winter, water droplets are easy to condense on the surface of the lampshade, which affects the light transmittance of the lampshade. At the same time, the existing lampshade has little bactericidal function.
