Problems solved by technology

[0002] At present, in lighting fixtures, in order to expand the lighting range, the general lampshade is mostly made of light-transmitting materials, and the light emission angle and reflection angle of the bulb are random. Expand the scope of lighting, but with the improvement of people's lighting requirements, such as the uniformity of light, the illuminance of light, and the increasing innovation of lighting technology, this kind of lampshade can no longer meet people's needs for lighting quality

Abstract

The invention provides a lamp cover, comprising a lamp cover body, wherein the cross section of the inner surface of the lamp cover body is a stepped cross section, the stepped cross section comprises an upper step surface and a lower step surface, the inner diameter of the upper step surface is smaller than that of the lower step surface, the upper step surface and the lower step surface are connected by a step, and the emergent angle of the lower step surface is greater than that of the upper step surface. The invention provides the lamp cover which is good in light uniformity and simultaneously ensures illumination range and illumination intensity.

Description

technical field [0001] The invention relates to a lampshade. Background technique [0002] At present, in lighting fixtures, in order to expand the lighting range, the general lampshade is mostly made of light-transmitting materials, and the light emission angle and reflection angle of the bulb are random. Expand the scope of lighting, but with the improvement of people's lighting requirements, such as the uniformity of light, the illuminance of light, and the increasing innovation of lighting technology, this type of lampshade can no longer meet people's needs for the quality of lighting. Contents of the invention [0003] In order to solve the above-mentioned technical problems in the background technology, the present invention provides a lampshade that can improve the lighting quality. [0004] The technical solution of the present invention is: the present invention is a lampshade, including a lampshade body, which is special in that: the cross section of the inner s...
