[0082] S204, attaching the reflective film to the same side of at least three light cone pieces, wherein the reflective portion is arranged corresponding to the light cone piece, and the fold is arranged corresponding to the joint between two adjacent light cone pieces.

[0083] S205, folding at least three light cone fragments along the folds to form a light cone in a manner that the convex structure faces the concave structure, and the convex structure is embedded in the concave structure.

[0084] During the process of folding the light cone scattered piece 101 along the fold 1022, the convex structure 201 will gradually approach the concave structure 202, and the folding angle of the light cone scattered piece 101 is determined by the structure of the light cone. After the folding is completed, the first light cone scattered piece 1011 will be aligned with the second light cone scattered piece 1012, thereby forming a light cone. The convex structure 201 will be embedded in the concave structure 202, so that the first light cone scattered piece 1011 and the second light cone scattered piece 1012 are fixed to each other.

[0095] The manufacturing method provided in the embodiment of the present invention strictly limits the placement position of the light cone diffuser through a jig, thereby improving the placement efficiency of the light cone diffuser and the accuracy of the position of the light cone diffuser, and the jig can also be used to align the reflective film and the light cone diffuser, so that the reflective film can be accurately attached to the light cone diffuser, thereby improving the accuracy and efficiency of manufacturing the light cone.

[0096] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
