The acrylic lampshade is made of acrylic material. Acrylic is also known as acrylic plastic. It is a thermoplastic resin containing -[ORO-CO]- links in the molecular backbone. It can be of the aliphatic, cycloaliphatic and aliphatic-aromatic types, of which aromatic polycarbonates are useful and bisphenol A type polycarbonates are important, typically having a molecular weight of 30,000 to 100,000.
If you want to make a lampshade, you must first choose a material. Usually, the three materials are PC, glass and acrylic. In the past, a lot of glass should have been used, just like many fluorescent lamps used in our homes. However, with the development, it has basically been replaced by acrylic or PC, the advantages of acrylic materials are more and more obvious, more and more LED fluorescent lamp manufacturers are using, and there are products made abroad.
Ceiling lampshade Due to the translucency of the acrylic lampshade product, the product is suspended and cooled evenly by the boy without being damaged by external forces, so that the inner and outer cooling of the product is kept constant, so that the molecular structure of the raw material is more dense and transparent. Sex is high. The lampshade manufacturer briefly stated that the product reaches about 95%; other products are formed under the action of up and down forces, resulting in inconsistent cooling inside and outside the product, and changing the molecular structure of the product, so that the light transmittance of the product reaches 90%.
After the fluorescent lamp lights up normally. Since the alternating current continuously flows through the coil of the ballast, a self-induced electromotive force is generated in the coil. Self-induced electromotive force hinders the change of current in the coil
