Embodiment 1

[0059] When the substrate 1 is molded by resin, the manufacturing method of the anti-glare lampshade for filtering blue light specifically includes the following steps:

[0060] 1) Cleaning and drying the substrate 1;

[0061] 2) Coating the outer surface of the substrate 1;

[0062] A. Coating the first film layer 2:

[0063] Adjust the vacuum degree in the vacuum coating chamber to less than or equal to 5.0×10 -3 Pa, and control the temperature in the vacuum coating chamber to 50-70°C, use an electron gun to bombard the film material of the first film layer 2, and the film material of the first film layer 2 evaporates and deposits on the outer surface of the substrate in the form of nano-scale molecules , while controlling the evaporation rate of the first film layer 2 to be 2.5 ? / S, the thickness of the first film layer 2 after the final formation is 10-100nm; wherein, the film material of the first film layer 2 is trititanium pentoxide , forming a trititanium pentoxide ...

Embodiment 2

[0079] When the substrate 1 is formed from glass, the manufacturing method of the anti-glare lampshade for filtering blue light specifically includes the following steps:

[0080] 1) Cleaning and drying the substrate 1;

[0081] 2) Coating the outer surface of the substrate 1;

[0082] A. Coating the first film layer 2:

[0083] Adjust the vacuum degree in the vacuum coating chamber to less than or equal to 5.0×10 -3Pa, and control the temperature in the vacuum coating chamber to 200-300°C, use an electron gun to bombard the film material of the first film layer 2, and the film material of the first film layer 2 evaporates and deposits on the outer surface of the substrate in the form of nanometer molecules , while controlling the evaporation rate of the first film layer 2 to be 2.5 ? / S, the thickness of the first film layer 2 after the final formation is 10-100nm; wherein, the film material of the first film layer 2 is trititanium pentoxide , forming a trititanium pentoxid...

Abstract

The invention discloses a lampshade capable of filtering blue light and preventing glare and a manufacturing method for the lampshade. The lampshade comprises a substrate, wherein the outer surface of the substrate is sequentially provided with a first film layer, a second film layer, a third film layer, a fourth film layer, a fifth film layer, a sixth film layer and a seventh film layer from inside to outside; the first film layer, the fourth film layer and the sixth film layer are trititanium pentoxide layers with a thickness of 10-100nm; the second film layer, the fifth film layer and the seventh film layer are silicon dioxide layers with a thickness of 50-100nm; and the third film layer is a metal layer with a thickness of 5-20n. The manufacturing method for the lampshade comprises the following steps: 1) cleaning the substrate; and 2) coating the outer surface of the substrate. The lampshade disclosed by the invention can effectively more than 33% of harmful blue light, and can filter harmful blue light and dazzle light to relieve visual fatigue.

Description

technical field [0001] The invention relates to the technical field of lampshades, in particular to a lampshade for filtering blue light and preventing glare 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 is, the more dama...
