Description

A kind of lampshade

Technical field

The utility model relates to a kind of lampshade.

Background technology

At present in lighting, general lampshade is in order to enlarge illumination zone, its lampshade is mostly to be made by the material of light-permeable, and the shooting angle of the light of bulb and reflection angle are random, therefore, though the lampshade that this type of lamp uses can enlarge illumination zone, but along with the raising of people to lighting requirement, as uniformity of light, the illumination of light, and the innovation day by day of lighting engineering, this type of lampshade can not satisfy people to the demand of the quality of illumination.

The utility model content

In order to solve the above-mentioned technical problem that exists in background technology, the utility model provides a kind of lampshade that improves lighting quality.

Technical solution of the present utility model is: the utility model is a kind of lampshade, comprise the lampshade body, its special character is: the cross section of described lampshade body internal surface is the cross section of step, the cross section of described step comprises appear on the stage terrace and leave from office terrace, appear on the stage the internal diameter of terrace less than the leave from office terrace, described appearing on the stage connects by step between terrace and leave from office terrace, and described terrace and the leave from office terrace of appearing on the stage is cambered surface, and the described terrace of appearing on the stage is identical with the height of leave from office terrace.

The utility model has the advantages that:

1, optical uniformity is good.The utility model is the cross section of step with the cross section of the inner surface in lampshade, makes light source not overlap in the focus of the light of lampshade internal reflection, and is good from the uniformity of light of lampshade mouth outgoing.
