Abstract

The invention discloses a water-based light diffusion coating capable of eliminating blue light, a preparation method and an LED lampshade adopting the water-based light diffusion coating. The coatingcomprises the raw materials in percentage by mass as follows: 15%-25% of deionized water, 0.1%-1% of a dispersant, 0.1%-0.5% of fumed silica, 0.1%-0.5% of a defoaming agent, 1%-5% of titanium dioxide, 5%-10% of organic silicon light diffusion powder, 20%-30% of inorganic light diffusion powder, 0.5%-5% of yellow fluorescent powder, 0.5%-1% of propylene glycol, 0.5%-2% of texanol, 30%-40% of acrylic resin emulsion, 0.1%-0.5% of a wetting agent and 0.1%-0.5% of a thickening agent. Light emitted by an LED lamp needs to be transmitted through the LED lampshade coated with the water-based light diffusion coating capable of eliminating blue light, so that all blue light can be eliminated, and the elimination rate is high and reliable.

Description

technical field [0001] The invention relates to the field of water-based light-diffusing coatings, in particular to a water-based light-diffusing coating for eliminating blue light, a preparation method and an LED lampshade using the same. Background technique [0002] "Blue light" refers to the part of visible light that is closest to ultraviolet light. The light frequency of these wavelengths in the range of 400-500 nanometers is slightly lower than that of ultraviolet light. It is the part with the highest energy in visible light. The colors are blue and purple, so it is commonly called for "Blu-ray". Blue light has the following hazards: [0003] The first is damage to the structure: Harmful blue light has extremely high energy, which can penetrate the lens and reach the retina, causing the retinal pigment epithelial cells to shrink or even die. The death of light-sensitive cells can lead to vision loss or even complete loss, and the damage is irreversible. Blue light...
