Problems solved by technology

Traditional internal white paint mostly uses white powder, the main components are halogen powder and matte powder. The halogen powder makes the light transmittance of the LED lampshade not good, and the matte powder cannot achieve the effect of light refraction, which makes the astigmatism of the LED lampshade not good.
Therefore, the light transmission efficiency of LED lamps in the prior art is not high enough, and the astigmatism is not large enough
[0004] Existing PC materials do not have the characteristics of high light transmittance and high astigmatism

Abstract

The invention relates to the electrical design field, and discloses a coat having a high light transmittance and a high astigmatism degree. The coat comprises 1-15% by mass of spherical organic silicon micro-powder, 0-5% by mass of square barium sulfate, 0-15% by mass of an inorganic filler, 20-90% by mass of a resin, 0-40% by mass of a solvent, 0-4% by mass of an assistant and 0-0.5% by mass of a coloring agent, and the spherical organic silicon micro-powder has a high light transmittance and a high astigmatism degree. The invention also discloses an LED lampshade having a high light transmittance and a high astigmatism degree. The LED lampshade comprises the coat and an LED lampshade body, and the coat is coated on the LED lampshade body. The invention also provides a PC material having a high light transmittance and a high astigmatism degree. The PC material is composed of 0.7-1.0% by mass of the spherical organic silicon micro-powder, 0-1.0% by mass of the square barium sulfate and 98-99% by mass of a transparent PC material, and the spherical organic silicon micro-powder has a high light transmittance and a high astigmatism degree. The PC material is used for preparing lampshades or sheets.

Description

technical field [0001] The invention and the field of electrical design particularly relate to a coating with high light transmittance and high astigmatism, an LED lampshade using the coating and a PC material with high light transmittance and high astigmatism. Background technique [0002] Traditional energy-saving lamps achieve luminescence and white appearance by spraying phosphor powder. In the process of packaging and powder spraying, mercury and other harmful substances are contained. [0003] LED lighting bulbs release a certain amount of heat during the lighting process, and most of them use glass shells, so the light is bright and dazzling. In order to make the light soft, beautiful and beautiful, and maintain a certain degree of light transmittance, white paint is usually painted on the LED lampshade to achieve the effect of astigmatism, light transmission and beauty. Traditional internal white paint mostly uses white powder, the main components are halogen powder...
