Embodiment Construction
[0031] refer to Figure 1-4 , the dual-channel light guide of the present invention includes an outer channel box body 1, an inner channel box body 4, a first light guide column 2 and a second light guide column 3, and the outer channel box body 1 includes a box capable of placing the first light guide column 2 The first accommodation groove, the inner channel box body 4 can also be placed in the first accommodation groove, and the inner channel box body 4 includes a second accommodation groove where the second light guide column 3 can be placed. In this embodiment, the outer passage box body 1 and the inner passage box body 4 both adopt a rectangular three-dimensional structure, and both of them adopt a structure with two side openings and a groove in the middle. Therefore, the outer passage box body 1 and the inner passage box The body 4 has two outer surfaces with larger areas and two outer end surfaces connected to each other, and the outer end surfaces separate the two ou...

The invention discloses a double-channel light guider. The double-channel light guider comprises an outer channel box body, an inner channel box body, a first light guide column and a second light guide column, wherein the outer channel box body comprises a first accommodating groove capable of placing the first light guide column; the inner channel box body can further be placed in the first accommodating groove; the inner channel box body comprises a second accommodating groove capable of placing the second light guide column; a first flange part arranged along a plane parallel to the outerside surface of the inner channel box body is arranged on the outer end surface of the inner channel box body; a third accommodating groove capable of accommodating the first flange part is formed inthe inner sidewall of the outer channel box body; a second flange part is formed between the first accommodating groove and the third accommodating groove; a light-absorbing material layer is furtherarranged on the outer end surface of the inner channel box body; and when the inner channel box body is mutually embedded with the outer channel box body, the first flange part is embedded into the third accommodating groove, and the end part of the second flange part is abutted against the light-absorbing material layer. The double-channel light guider disclosed by the invention is capable of effectively solving the problems of light leakage and light crosstalk of double channels.
Description
technical field [0001] The invention belongs to the field of light guide technology, and in particular relates to a double-channel light guide. Background technique [0002] The light guide changes the light direction of the LED light through the bending and deformation structure of the light guide column, and transmits the light of the LED light to the outside of the equipment, so that it is convenient to monitor and judge the working status of related equipment in the machine according to the light derived from the light guide column; the existing The light guide generally uses multiple light guide rods to realize the LED light on the PCB inside the device to be transmitted to the outside of the device, but when multiple light guide rods are used side by side, it is easy to appear left and right, up and down string lights between every two light guide rods Or the problem of light leakage, which leads to the problem of inaccurate working status of the observation equipment,...
