Problems solved by technology

At present, many anti-blue light sources on the market are based on coating technology to make anti-blue plexiglass lampshades, thereby filtering out most of the blue light, but this technology is to reflect the blue part of the light source, so the total brightness of the light source appears. A certain degree of attenuation affects the user's visual clarity, and the yellowing of the light source affects the user's judgment of color

Embodiment 1

[0026] An anti-blue light and anti-fog plexiglass lampshade, the composition of the plexiglass lampshade is represented by weight percentage: 0.1% coumarin 540, 0.1% silver nanoparticles, 70% methyl methacrylate, 15% acrylic acid, 3 % methacrylic acid, 1.5% β-hydroxyethyl methacrylate, 10% N-methylol acrylamide, 0.5% azobisisobutyronitrile, and the average thickness of the light-transmitting surface of the plexiglass lampshade is 3 millimeters.

[0027] A method for preparing the plexiglass lampshade, the steps are as follows:

[0028] 1) Pre-polymerization: first put the above components in a container and mix them evenly with a stirrer, then keep stirring, heat the pre-polymerization in a water bath at 85-90°C for 0.5-1 hour, the mixture in the above container will form a viscous thin slurry, Then rapidly cool to room temperature to obtain the prepolymer;

[0029] 2) Grouting: Slowly inject the prepolymer into the mold corresponding to the plexiglass lampshade to prevent th...

Embodiment 2

[0033] An anti-blue light and anti-fog plexiglass lampshade, the composition of the plexiglass lampshade is represented by weight percentage: 0.25% coumarin 540, 0.25% silver nanoparticles, 75% methyl methacrylate, 14% acrylic acid, 2 % methacrylic acid, 2% β-hydroxyethyl methacrylate, 5% N-methylolacrylamide, 1.5% azobisisobutyronitrile, the average thickness of the transparent surface of the plexiglass lampshade is 3 mm.

[0034] The method for preparing the plexiglass lampshade is the same as in Example 1.

Embodiment 3

[0036] An anti-blue light and anti-fog plexiglass lampshade, the composition of the plexiglass lampshade is represented by weight percentage: 0.5% coumarin 540, 0.5% silver nanoparticles, 72.5% methyl methacrylate, 12% acrylic acid, 2 % methacrylic acid, 2% β-hydroxyethyl methacrylate, 9% N-methylol acrylamide, 1.5% azobisisobutyronitrile, and the average thickness of the light-transmitting surface of the plexiglass lampshade is 3 millimeters.

[0037] The method for preparing the plexiglass lampshade is the same as in Example 1.

Abstract

The invention discloses an anti-blue light and anti-fog plexiglass lampshade. The components of the plexiglass lampshade are represented by weight percentage: 0.1-0.5% coumarin 540, 0.1-0.5% silver nanoparticles, 70-75% methacrylic acid Methyl ester, 12‑15% acrylic acid, 2‑3% methacrylic acid, 1.5‑2% beta-hydroxyethyl methacrylate, 5‑10% N‑methylolacrylamide, 0.5‑1.5% azobisiso Nitrile, the average thickness of the light-transmitting surface of the plexiglass lampshade is 3-6 mm, Coumarin 540 can absorb most of the blue light in the LED light source in a targeted manner, and at the same time emit green and yellow light through fluorescent radiation, which can make The total brightness attenuation of the light source is small, which does not affect the clarity of the user's vision. The light emitted by the light source through the present invention is light white, which will not affect the user's color judgment. Excellent hydrophilicity, realize the continuous anti-fog effect of the plexiglass lampshade.

Description

technical field [0001] The invention relates to a component of an illuminating device, in particular to a lampshade. Background technique [0002] LED lighting sources are widely used as light sources due to the advantages of energy saving, small size, and durability. However, the white light source of LEDs produces a large amount of blue light, which is harmful to human eyes. Therefore, eliminating the hazards of LED blue light has always been a research in the field of lighting. hotspot. At present, many anti-blue light sources on the market are based on coating technology to make anti-blue plexiglass lampshades, thereby filtering out most of the blue light, but this technology is to reflect the blue part of the light source, so the total brightness of the light source appears. A certain degree of attenuation affects the clarity of the user's vision, and the yellowing of the light source affects the user's judgment of color. Contents of the invention [0003] In order ...
