Anti-blue-light and anti-fog polymethyl methacrylate lampshade

Abstract

The invention discloses an anti-blue-light and anti-fog polymethyl methacrylate lampshade. The polymethyl methacrylate lampshade comprise, by weight, 0.1-0.5% of coumarin 540, 0.1-0.5% of silver nanoparticles, 70-75% of methyl methacrylate, 12-15% of acrylic acid, 2-3% of methacrylic acid, 1.5-2% of beta-hydroxyethyl methacrylate, 5-10% of N-hydroxymethyl acrylamide and 0.5-1.5% of azobisisobutyronitrile, the average thickness of the light transmitting surface of the polymethyl methacrylate lampshade is 3-6 mm, and the coumarin 540 can specifically absorb most of blue light in an LED light source. At the same time, green light and yellow light are emitted by fluorescent radiation, so that the total brightness of the light source can be attenuated less, the visual clarity of a user is not affected, light emitted by the light source through the anti-blue-light and anti-fog polymethyl methacrylate lampshade is light white, the anti-blue-light and anti-fog polymethyl methacrylate lampshadedoes not affect color judgment for the user, and by direct regulation of the hydrophilicity of the methyl methacrylate, the continuous anti-fog effect of the polymethyl methacrylate lampshade is achieved.

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 ...
