Manufacture method of anti-glare lampshade

Abstract

The invention relates to a manufacture method of an anti-glare lampshade, comprising the following steps: providing a macromolecular substrate; carrying out a fixed refinement procedure to a diffusant, an additive and the macromolecular substrate so as to generate the plastic mother granules of the anti-glare lampshade; and providing a lampshade mould and utilizing the lampshade mould to carry out an ejection procedure by the plastic mother granules. The anti-glare lampshade can be a nonplanar circular arc light diffusion plate. The anti-glare lampshade comprises the macromolecular substrate, the diffusant and the additive, wherein the macromolecular substrate accounts for 90-99.8 of the anti-glare lampshade by weight percent, the diffusant accounts for 0.1-6 of the anti-glare lampshade by weight percent, the additive accounts for 0.1-4 of the anti-glare lampshade by weight percent, and the minimum thickness of the anti-glare lampshade is more than 0.5mm. The invention can solve the defects that the existing anti-glare film has to additionally expend a sticking expense, can generate air bubbles or crimples when being inadequately stuck and can generate air bubbles because of temperature or material aging after being used for a period of time.

Description

technical field [0001] The invention relates to a manufacturing method, in particular to a manufacturing method of an anti-glare lampshade. Background technique [0002] At present, in order to provide better lighting quality, almost all desk lamps have added anti-glare function. Among them, the means of adding anti-glare to lighting equipment are mainly divided into two categories. The first one is to improve the structure of the light source, such as anti-glare net, which aims to control the direction of light and isolate the glare phenomenon. The second is to paste one or more layers of optical film on the lampshade, such as a reflective filter, which is to add a light-transmitting optical film on the upper and lower sides of the filter, so that each beam of light is evenly transmitted to the entire film. filter. In addition, although the polarizing film used in the general polarizing plate can also prevent glare, it must pay the price of greatly reducing the brightness...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the defects in the existing anti-glare lampshade manufacturing method, and provide a new anti-glare lampshade manufacturing method, the technical problem to be solved is to make it possible to solve the existing known anti-glare film The disadvantage of spending an additional paste fee; and it can solve the shortcomings of the existing known anti-glare film that will produce bubbles or wrinkles when it is improperly pasted; and the existing known anti-glare film After being used for a period of time, The disadvantage of air bubbles with temperature or material aging is very suitable for practical use
