Problems solved by technology

[0004] In order to solve the problems of using the LED bulb lamps, downlights and other lighting fixtures produced by the prior art, the spatial light-emitting angle is too small, especially the problem that the middle emits more light and the brightness is high, and the edge emits less light and the brightness is low. Improvements were made to provide a new type of lampshade

Embodiment 2

[0040] In the first step, Dow Corning 3140 alkoxy silica gel and silicon dioxide particles are mixed to form a mixture I with a silicon dioxide mass concentration of 15% and loaded into the first spraying equipment. The average particle size of the silicon dioxide particles used in this step is The diameter is 100 μm;

[0041] The second step is to mix Dow Corning 3140 alkoxy silica gel and glass particles to form a mixture II with a silica mass concentration of 40% and put it into the second spraying equipment. The average particle size of the glass particles used in this step is 200 μm ;

[0042] The third step is to open the lampshade body 1 downwards, spray the mixture I in the first spraying equipment on the top 5 of the lampshade body 1, and let the mixture I flow from the top 5 of the lampshade body 1 to the open end 6 of the lampshade body 1, In order to speed up the flow of the paint, it can be assisted with proper rotation to allow the lampshade body 1 to rotate aro...

Embodiment 3

[0046] The first step, mixing Dow Corning 1-2577 silica gel and silicon dioxide particles into a mixture I with a silicon dioxide mass concentration of 40% and loading it into the first spraying equipment, the average particle diameter of the silicon dioxide particles used in this step is 1000 μm;

[0047] In the second step, Dow Corning 1-2577 silica gel and glass particles are mixed into a mixture II with a silica mass concentration of 15% and loaded into the second spraying equipment. The average particle size of the glass particles used in this step is 2000 μm;

[0048] The third step is to open the lampshade body 1 downwards, spray the mixture I in the first spraying equipment on the top 5 of the lampshade body 1, and let the mixture I flow from the top 5 of the lampshade body 1 to the open end 6 of the lampshade body 1, In order to accelerate the flow of the mixture, appropriate rotation can be assisted to allow the lampshade body 1 to rotate around the central axis, and...

Embodiment 4

[0052] The first step, mixing Dow Corning 1-2577 silica gel and silicon dioxide particles into a mixture I with a silicon dioxide mass concentration of 40% and loading it into the first spraying equipment, the average particle diameter of the silicon dioxide particles used in this step is 1 μm;

[0053] In the second step, Dow Corning 1-2577 silica gel and glass particles are mixed into a mixture II with a silica mass concentration of 15% and loaded into the second spraying equipment. The average particle size of the glass particles used in this step is 500 μm;

[0054] The third step is to open the lampshade body 1 downwards, spray the mixture I in the first spraying equipment on the top 5 of the lampshade body 1, and let the mixture I flow from the top 5 to the opening end 6 of the lampshade body 1, in order to accelerate the mixture I The flow can be assisted by proper rotation to allow the lampshade body 1 to rotate around the central axis, relying on centrifugal force to ...

Abstract

The invention provides a lampshade, which is a lamp accessory and is mainly used in the fields of LED bulb lamps, LED downlights and the like. It includes a lampshade body, a first coating and a second coating on the inner wall of the lampshade body; the first coating is made by curing the mixture of glue and first particles; the second coating is made of glue and The mixture of the second particles is cured; the first particles and the second particles are light-transmitting particles; the first coating and the second coating are taken as a whole, and the thickness is from near the top of the lampshade to the opening of the lampshade The ends gradually change from thick to thin. The manufacturing method includes: mixing the glue with the first particle and the second particle uniformly respectively, and then coating the inner wall of the lampshade successively, and then curing. Compared with the traditional lampshade, the lampshade adds a coating to the arc-shaped end of the lampshade, that is, the position where the light of the light source is directly irradiated, so that the light extraction rate at this position is reduced and the scattering rate is increased.

Description

technical field [0001] The invention provides a lampshade, which is a lamp accessory and is mainly used in the fields of LED bulb lamps, LED downlights and the like. Background technique [0002] LED bulb lamps and downlights are currently being used more and more widely, and are rapidly replacing incandescent and fluorescent lamps. The main components of current LED bulb lamps and downlights are basically similar, including lamp holders, radiators, driving power supplies, light sources, and lampshades. For bulb lamps and downlights, people widely use frosted glass, PC or PMMA with diffusing agent, or coat a layer of diffusing agent represented by silicon dioxide on the glass surface to achieve full mixing of light in the lampshade , to reduce the amount of light emitted in the direct direction of the light. However, since the overall diffusion effect and light transmittance of the lampshade products manufactured by the above-mentioned methods are the same, the following pr...
