Description

Technical Field

[0001] The utility model relates to the technical field of light guide columns, in particular to a light guide column structure and an indicator light. Background Art

[0002] A light guide is a device that transmits light from one light source to another point a certain distance away with minimal loss. It is typically made of optical materials such as transparent PC and PMMA. As product appearance requirements become increasingly demanding and curved surfaces are increasingly common, the structure of the light guide is particularly important in many indicator light products.

[0003] Existing indicator light products with curved exterior surfaces generally adopt a shell + multiple identical light guide column structure. Another type of structure is a shell + multiple different light guide column structure. Although the shell + multiple identical light guide column structure solves the problem of different light guide columns caused by the curved exterior surface of the shell, under this structure, the gaps between each light guide column and the shell are different, which affects the light guiding effect; the shell + multiple different light guide column structure is prone to errors during assembly, which is not conducive to mass production of products; therefore, it is necessary to design a new light guide column structure to solve the above problems.
