Embodiment Construction

[0027] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In the drawings, the same or similar parts are denoted by the same or similar reference numerals. In order to avoid obscuring the gist of the present invention due to unnecessary details, only structures and components closely related to the solutions of the present invention are shown in the drawings, while other details that are not relevant are omitted.

[0028] see Figure 1A and Figure 1B . Figure 1A is a cross-sectional view showing the microstructure on the lamp housing 100 in the prior art. Reference numeral 101 denotes a groove structure on the surface (inner surface) of the lamp housing 100 facing the light source. The plurality of grooves 101 form a discontinuous microstructure on the inner surface of the lamp housing 100 with a cross-sectional profile curve. Figure 1B is shown using Figure 1A The diagram of the lighting effect of the lam...

Abstract

The invention relates to a lamp shell, a lamp with the lamp shell and a manufacturing method for the lamp shell. At least one part of at least one surface of the lamp shell comprises staggered convex ridges and grooves, wherein the outlines of each convex ridge and each groove are of arc in the outline of at least one part acquired in the orthogonal direction along the extending directions of the convex ridges or the grooves, and the arcs of the adjacent convex ridges and grooves are tangential. The lamp shell can avoid forming dark lines on the illumination surface and obtain good illumination uniformity.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a lamp housing, a lamp with the lamp housing and a manufacturing method of the lamp housing. Background technique [0002] Various lamps are widely used. For purposes of dust prevention and aesthetics, the light-emitting part of the lamp is usually covered with a light-transmitting shell, which is referred to as a lamp shell herein. During the process of production, installation and use, scratches and stains may occur on the surface of the lamp housing, or in order to achieve a decorative effect, the outer surface of the lamp housing may have various flower decorations. These all have an impact on the lighting effect, creating dark shadows and unevenness on the illuminated surface. [0003] In the prior art, generally, some microstructures, such as ribs or grooves, are applied on the lamp housing to make the light irradiated on the lighting surface more uniform and to hide floral decora...
