Abstract

The utility model provides a lamp shade which comprises a lamp shade body. The inner surface of the lamp shade body is provided with a reflecting surface which is made of a reflecting panel or reflecting cloth or is directly a coating of reflecting material. The cross section of the inner surface of the lamp shade body is stepped. The stepped cross section includes an upper stepped surface and a lower stepped surface. The upper stepped surface is smaller than the lower stepped surface in inner diameter. The upper stepped surface is connected with the lower stepped surface through a step. Both the upper stepped surface and the lower stepped surface are cambered. The upper stepped surface and the lower stepped surface are equal in height. The lamp shade is fine in light uniformity. The lamp shade is fine in light uniformity and allows lighting to be higher in quality.

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: described lampshade body internal surface is provided with reflective surface, described reflective surface is reflector, reflective fabric or directly applied by reflectorized material forms, 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, described terrace and the leave from office terrace of appearing on the stage is cambered surface, 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, the quality of illumination is provided.The utility model makes the light that light source sends can't project lampshade by reflective surface is set in lampshade, in lampshade after Circulated reflection from the outgoing of lampshade mouth, greatly improved the illumination of light, and uniformity of light, improved the quality of illumination.

2, 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.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Referring to Fig. 1, the utility model provides a kind of lampshade, comprises lampshade body 5, and lampshade body 5 inner surfaces are provided with reflective surface 1, and described reflective surface 1 is reflector, and reflective fabric or directly applied by reflectorized material forms.The cross section of lampshade body 5 inner surfaces is the cross section of step, and the cross section of step comprises appear on the stage terrace 3 and leave from office terrace 4, and the internal diameter of the terrace 3 of appearing on the stage is less than leave from office terrace 4, and appearing on the stage connects by step 2 between terrace 3 and leave from office terrace 4.Be further to improve the uniformity of light outgoing, terrace 3 and the leave from office terrace 4 of appearing on the stage of the present utility model is cambered surface, and the terrace 3 of appearing on the stage is identical with the height of leave from office terrace 4.

Claims (1)

1. lampshade, comprise the lampshade body, it is characterized in that: described lampshade body internal surface is provided with reflective surface, described reflective surface is reflector, reflective fabric or is directly formed by the reflectorized material coating, 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, 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.
