Anti-radiation anti-reflection lampshade capable of filtering blue light and manufacturing method thereof

Abstract

The invention discloses an anti-radiation anti-reflection lampshade capable of filtering blue light and a manufacturing method thereof. The lampshade comprises a substrate, and 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 sequentially arranged on the outer surface of the substrate from inside to outside. The first film layer, the fourth film layer and the sixth film layer are all trititanium pentoxide layers and are 10-100 nm thick. The second film layer, the fifth film layer and the seventh film layer are all silicon dioxide layers and are 50-100 nm thick. The third film layer is a metal layer and is 5-20 nm thick. The eighth film layer is an indium tin oxide (ITO) layer and is 10-100 nm thick. The ninth film layer is an acrylic acid layer and is 5-15 nm thick. The manufacturing method of the lampshade includes the following steps of (1) cleaning the substrate and (2) coating the outer surface of the substrate. The lampshade can filter the harmful blue light and dazzle light and has an anti-radiation property, and the anti-reflection performance can be improved.

Description

technical field [0001] The invention relates to the technical field of lampshades, in particular to a lampshade for filtering blue light to prevent radiation and enhance 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 comp...

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 anti-radiation function.
