Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

a lamp cup, as shown in fig. 1 and 2, comprises a lamp cap interface part 10 and a cover body part 20, wherein the cover body part 20 and the lamp cap interface part 10 are of an integrally formed structure, and the lamp cap interface part 10 and the cover body part 20 are both made of plastic materials. Compared with a glass lamp cup, the lamp cup made of the plastic material is lighter in weight, simpler in production process and higher in precision. The cover body part 20 is in a bowl-shaped structure, and the outer surface of the cover body part is provided with a refraction layer which is made of transparent plastics. The refraction layer comprises a plurality of regularly arranged pyramid units, and each pyramid unit shares the same bottom edge with at least one other pyramid unit. The refraction layer has no gap, all the spaces are filled with the pyramid units, and all the pyramid units have the same size and are arranged regularly.

The pyramid unit in the embodiment adopts a regular rectangular pyramid 100, as shown in fig. 3, the vertex angle range of the side triangle of the regular rectangular pyramid is 60 degrees to 90 degrees, and the most preferable value is 86.6 degrees, and in actual production, it is found that when the angle of the side triangle of the regular rectangular pyramid exceeds the range of 60 degrees to 90 degrees, the phenomena of stripping and undercut are easy to occur, and the requirements on the production process are very strict. In addition, after the product appearance, the product weight and the production difficulty are comprehensively considered, the fact that when the vertex angle of the side triangle is designed to be 86.6 degrees and the height of the vertex of the regular rectangular pyramid from the bottom surface is 0.1-1 mm is found, the obtained product can meet the requirements of attractive appearance, proper weight and controllable production cost.

As shown in fig. 4, the regular rectangular pyramid 100 located at the upper edge of the outer surface of the cap portion 20 is connected to the base interface portion 10 via the polyhedral unit 200, so that the appearance of the product is complete and beautiful, the polyhedral unit 200 has a left-right symmetrical structure, and the vertices of the regular rectangular pyramid 100 and the polyhedral unit 200 are located at the same height.

As shown in fig. 5, a light ray 1 is incident on the surface of a regular rectangular pyramid, and a reflected light ray 2 forms surface light on the surface due to reflection; the light 3 is incident on the inner surface of the regular rectangular pyramid, and the reflected light 4 forms internally bright light on the inner surface due to total reflection on the inner surface. Therefore, light rays are reflected on the surface or the inner surface of the regular rectangular pyramid, so that the surface or the inner surface of the regular rectangular pyramid forms bright light, and the effect of bright light similar to diamond is achieved, and the transparent plastic looks like glass. When the light 5 is emitted outwards from the inner side of the lamp cup through the regular rectangular pyramid, the regular rectangular pyramid is of a structure with thick middle and thin four surfaces, and the light is refracted, so that the light which comes out from the inside cannot be directly received from the outside, and the effect of hiding the inside of the lamp cup is achieved.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
