Problems solved by technology

[0005] Traditional LED bulb lamp shades are generally made of ordinary glass or ordinary PC materials. Because glass or PC materials have low thermal conductivity, ordinary LED bulb lamp shades can only play the role of mixing light and cannot achieve any transmission. The role of heat and heat dissipation

Abstract

The invention discloses a manufacturing method of an LED bulb lampshade. Polypropylene, polymethyl methacrylate, silicon resin, methyl acryloyloxy silane and other combinations are adopted to undergohybrid heating and then undergo integrally-formed injection molding to form the LED bulb lampshade, the related heat dissipation lampshade is formed in the way that hybrid heating of the above multiple kinds of materials is performed, then the materials flow into an injection molding machine mold for one-time forming, then the mold is cooled in a water-cooling mode, then the lampshade is turned tobe a final lampshade finished product through demolding, the problems of an existing LED bulb lamp lampshade in the aspects of heat conduction and heat dissipation are solved through the lampshade, so that the lampshade of the LED bulb lamp has a light mixing function and also has a heat dissipation function, meanwhile, innovation is also made in the aspect of the structure, so that the lampshadeis simpler and more convenient to install.

Description

【Technical field】 [0001] The invention relates to the technical field of heat dissipation of LED lamps, in particular to a lampshade with excellent heat dissipation capability and a formula for making the lampshade. 【Background technique】 [0002] LED bulb lamp is a common lamp with LED light-emitting diode as the light source. It is widely used in various occasions such as homes, shopping malls, hotels, and office buildings. Low heat, light color rendering refers to advanced technical features, is becoming the main product of the new generation of lighting market, and effectively stimulate the rapid development of environmental protection and energy saving industry. [0003] Since the LED light source emits light at a solid point, the light is relatively concentrated. If no optical accessories are installed outside the light source, it will emit too concentrated and high-intensity light. For human vision, the light is too strong and too dazzling. The light source that dire...
