Description

Technical Field

[0001] This utility model relates to the field of optical fiber technology, specifically to an optical fiber with good light guiding effect. Background Technology

[0002] Optical fiber has significant advantages over traditional light guides in complex applications (long optical paths, limited space, etc.). During assembly, one end of the optical fiber is fixed to the PCB board to receive the LED light source on the PCB, while the other end is fixed to the light-emitting panel. Because optical fiber is a flexible component, it can be arranged arbitrarily. However, existing optical fibers can only guide light from one end to the other, resulting in a relatively dim optical fiber body and ineffective illumination. Furthermore, most optical fibers are fixed with adhesive, but this method is inefficient and the adhesive can easily contaminate the fiber, affecting its light transmittance. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a light-guiding optical fiber with good light-guiding effect.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a light guiding optical fiber with good light guiding effect, comprising an optical fiber body with a circular cross-section, and one or more reflective grooves arranged along the length direction of the optical fiber body.

[0006] As a preferred technical solution of this utility model, the end of the optical fiber body is provided with a docking mechanism for docking with a light source. The docking mechanism includes an insertion tube provided at the end of the optical fiber body and a connecting tube provided on the light source. The insertion tube is inserted into the connecting tube, and the tail of the insertion tube is fixed to the end of the optical fiber body via a heat shrink tube. The insertion tube and the connecting tube are interference-fitted.

[0007] As a preferred embodiment of this utility model, the reflective groove is a V-shaped groove.

[0008] As a preferred embodiment of this utility model, the reflective grooves are provided in a plurality of manner and are distributed along the axial direction of the optical fiber body.

[0009] As a preferred embodiment of this invention, the reflective grooves are no less than three.

[0010] As a preferred embodiment of this utility model, the end of the insertion tube is provided with an inwardly contracting guide portion.

[0014] The beneficial effects of this utility model are:

[0015] This type of optical fiber with good light guiding effect has one or more reflective grooves arranged along the length of the optical fiber body. When light propagates within the circular optical fiber body, the reflective grooves form a tangent on the light propagation surface, causing some light to escape through the reflective grooves, thus increasing the brightness of the optical fiber body and achieving the effect of light enhancement. The use of plug-in connectors and inserts facilitates the fixation of the optical fiber body, making it less likely to detach from the light source during daily use. It features a simple structure and is easy to manufacture. Attached Figure Description

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figure 1 , Figure 2 , Figure 3As shown, this utility model discloses a light-guiding optical fiber with good light-guiding effect, including an optical fiber body 1 with a circular cross-section. The optical fiber body 1 is provided with one or more reflective grooves 2 arranged along the length direction of the optical fiber body 1. The end of the optical fiber body 1 is provided with a docking mechanism 3 for docking with a light source. The docking mechanism 3 includes an insertion tube 4 provided at the end of the optical fiber body 1 and a connecting tube 5 provided on the light source. The insertion tube 4 is inserted into the connecting tube 5, and the tail of the insertion tube 4 is fixed to the end of the optical fiber body 1 through a heat-shrink tubing 7. The insertion tube 4 and the connecting tube 5 are interference-fitted. By providing multiple reflective grooves 2 along the length of the optical fiber body 1, when light propagates within the circular optical fiber body 1, the reflective grooves form a tangent on the light propagation surface, causing some light to exit through the reflective grooves 2, thus increasing the brightness of the optical fiber body 1; thereby achieving the effect of enhancing light; the use of plug-in connectors 5 and connectors 4 facilitates the fixation of the optical fiber body, preventing it from easily detaching from the light source during daily use, and features a simple structure and ease of manufacturing.

[0023] The reflective groove 2 is a V-shaped groove, which is easy to manufacture.

[0024] The reflective grooves 2 are provided in several ways and are distributed along the axial direction of the optical fiber body 1, so that the optical fiber body 1 has good light emission intensity. There are no fewer than three reflective grooves 2.

[0025] The insertion tube 4 has an inwardly tapering guide 8 at its end, facilitating insertion into the connecting tube. The reflective groove 2 has a depth of 0.5mm-2mm, minimizing damage to the optical fiber and preventing breakage.

[0026] The outer surface of the insertion tube 4 is provided with anti-slip grooves 9, which play an anti-slip role and facilitate insertion and removal. The end of the connecting tube 5 is provided with a stop block 10, which facilitates the blocking of the connecting tube 5 during insertion and removal, and then the insertion tube is inserted and removed.

[0027] During operation, this type of light-guiding optical fiber with good light-guiding effect has multiple reflective grooves 2 arranged along the length of the optical fiber body 1. When light propagates within the circular optical fiber body 1, the reflective grooves form a tangent on the light propagation surface, causing some light to be emitted through the reflective grooves 2, thus increasing the brightness of the optical fiber body 1 and achieving the effect of enhancing light. The use of plug-in connectors 5 and connectors 4 facilitates the fixation of the optical fiber body, making it less likely to detach from the light source during daily use. It has the characteristics of simple structure and easy manufacturing.
