Problems solved by technology

[0003] In the prior art, in order to improve the atomization effect of the LED lampshade and increase the light transmittance, technicians have proposed many solutions, such as the application number "201010139330.0" and the patent name "A lampshade coating and its preparation method" The Chinese invention patent, which uses a lampshade coating, which can have a good atomization effect on the light after being coated on the inner surface of the lampshade, improve the light transmittance, and increase the luminous intensity; but this kind of molding is carried out after The method of coating is equivalent to the secondary processing of the lampshade, which not only needs to overcome the yield rate of finished products brought about by the secondary processing, but also makes it difficult to obtain cost advantages by secondary coating

Abstract

The invention relates to the technical field of a lampshade, in particular to an LED lampshade and a processing process thereof. The LED lampshade comprises the following materials in parts by weight:80 to 125 parts of polycarbonate, 12 to 20 parts of PMMA resin, 0.5 to 3 parts of MBS, 3 to 7 parts of reinforced fiber, 5 to 10 parts of mixture and 0.3 to 2 parts of other functional aid, wherein the mixture is obtained by compounding SiO2 and TiO2 according to the weight ratio of 1:(1-2.5). The processing process comprises the following steps: spraying the inner surface of the LED lampshade byusing a hydrofluoric acid solution with the concentration of 40 to 60 percent after the LED lampshade is formed, standing for 3 to 5 minutes, washing with deionized water and drying to obtain an LEDlampshade finished product. According to the LED lampshade provided by the invention and through overall consideration on the composition formula of the lampshade and the final structure of the product, the LED lamp which is convenient to process and has high diffusion property is obtained, has excellent dodging effect and avoids undesirable phenomena of facula, halo and the like on the basis of guaranteeing high light-transmitting performance.

Description

technical field [0001] The invention relates to the technical field of lampshades, in particular to an LED lampshade and a processing technology thereof. Background technique [0002] LED lampshade is a kind of LED accessories. Its function is to better gather light, make the light more concentrated and softer, and avoid direct glare of LED light. In addition to high flame retardancy and high impact strength, LED lampshades also need high light transmission and high diffusion performance, so as to improve the utilization rate of light energy. [0003] In the prior art, in order to improve the atomization effect of the LED lampshade and increase the light transmittance, technicians have proposed many solutions, such as the application number "201010139330.0" and the patent name "A lampshade coating and its preparation method" The Chinese invention patent, which uses a lampshade coating, which can have a good atomization effect on the light after being coated on the inner sur...
