Abstract

The utility model provides a desk lamp which comprises a lamp holder, a lamp shade and a light source. A body of the lamp shade is made of a reflecting material which is PVC (polyvinyl chloride), the cross section of the inner surface of the body of the lamp shade 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 is connected with the lower step surface by a step, both the upper step surface and the lower step surface are cambered surfaces, the height of the upper step surface is identical to that of the lower step surface, and the light source is arranged in the upper step surface. The desk lamp has the advantages that light rays emitted via an inner lamp shade are soft, the inner lamp shade is good in optical uniformity, and the illuminating quality is improved owing to the inner lamp shade.

Description

A kind of desk lamp

Technical field

The utility model relates to a kind of desk lamp.

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 desk lamp that improves lighting quality.

technical solution of the present utility model is: the utility model is a kind of desk lamp, comprise lamp socket, lampshade and light source, its special character is: described lampshade body is made by reflectorized material, described reflectorized material is PVC, 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, described light source is arranged in the terrace of appearing on the stage.

The utility model has the advantages that:

1, improve lighting quality.The utility model is made the lampshade body by reflectorized material, make the light that light source sends can't project 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.

3, light is soft.The utility model is arranged on light source in the terrace of appearing on the stage, the emergent light of light source after the terrace internal reflection of appearing on the stage, outgoing after the leave from office terrace, emergent light light is soft, is suitable for vision protection.
