Description

Optical fiber module and light source module

The present disclosure relates to an optical fiber module and a light source module.

Generally, optical fiber cloth, which is a blend of optical fiber bundles and yarns, needs to be bundled into a bundle, then manually wrapped with tape or fixed with a round metal sheet, and the ends of the optical fiber bundles are polished flat by cutting or polishing equipment to complete the optical fiber bundling operation of the optical fiber cloth. Finally, it is combined with the RGB light source module through a bundling clip to be used for various atmospheric lighting effects.

However, the current manual bundling method of wrapping the fiber bundle with manual tape or clamping it with a metal ring is not only time-consuming and labor-intensive and difficult to mass-produce, but also easily causes a large tolerance in the diameter of the fiber bundle due to the manual bundling method, resulting in the need for repeated manual adjustments to the fiber bundle diameter to be consistent during subsequent assembly with the light source. Moreover, if the manual bundling is not tight enough, it is easy for the optical fibers closer to the center to slip and fall off. In addition, for fiber bundles of different diameters, the current method also requires manual adjustment of the optimal light-guiding distance between them and the light source module. Therefore, the current fiber optic module and the corresponding light source module are still very inconvenient to assemble.

The present disclosure provides an optical fiber module and a light source module using the same, which can easily adjust the clamping tightness of the optical fiber bundle and effectively control the diameter of the optical fiber bundle, and can easily adjust and fix the light guiding distance between the optical fiber bundle and the light source module.

In one embodiment of the present disclosure, an optical fiber module includes an optical fiber bundle, an elastic telescopic sleeve, a clamping claw sleeve, a sleeve and a clustering member. The elastic telescopic sleeve is mounted on the optical fiber bundle. The clamping claw sleeve is mounted on the elastic telescopic sleeve and includes a clamping claw, which is arranged at the end of the clamping claw sleeve to clamp the elastic telescopic sleeve. The sleeve is mounted outside the clamping claw sleeve. The clustering member is located between the sleeve and the clamping claw sleeve and includes a first end close to the end of the optical fiber bundle and a second end opposite to the first end, and the aperture of the first end is substantially smaller than the aperture of the second end.

In one embodiment of the present disclosure, the elastic expansion sleeve includes a plurality of annular grooves that surround the elastic expansion sleeve at intervals.

In one embodiment of the present disclosure, the depth of each of the plurality of annular grooves is substantially less than the thickness of the side wall of the elastic expansion sleeve.

In one embodiment of the present disclosure, the elastic telescopic sleeve includes a plurality of longitudinal grooves extending along the long axis direction of the elastic telescopic sleeve.

In one embodiment of the present disclosure, a plurality of longitudinal grooves extend along the long axis direction of the elastic expansion sleeve, and are arranged alternately along the long axis direction.

In one embodiment of the present disclosure, a plurality of longitudinal grooves penetrate the side wall of the elastic expansion sleeve.

In one embodiment of the present disclosure, the outer surface of the bundle includes threads so as to be tightened into the sleeve by rotation in a direction away from the end of the optical fiber bundle.

In an embodiment of the present disclosure, the aperture of the clustering element gradually increases from the first end to the second end.

In one embodiment of the present disclosure, a light source module includes an optical fiber module and a light source base. The optical fiber module includes an optical fiber bundle, an elastic telescopic sleeve, a clamping claw sleeve, a sleeve and a bundling piece. The elastic telescopic sleeve is mounted on the optical fiber bundle. The clamping claw sleeve is mounted on the elastic telescopic sleeve to clamp the elastic telescopic sleeve. The sleeve is mounted outside the clamping claw sleeve and includes a plurality of sleeve positioning pieces arranged on the outer surface of the sleeve, which are arranged along the long axis direction of the optical fiber bundle. The bundling piece is located between the sleeve and the clamping claw sleeve. The light source base includes a base and a light source arranged in the base, wherein the inner side surface of the base includes a base positioning piece, the optical fiber module is arranged in the light source base, and the base positioning piece is used to engage with one of a plurality of sleeve positioning pieces to fix the distance between the optical fiber bundle and the light source.

In an embodiment of the present disclosure, the sleeve further includes an adjusting member for being pressed by an external force to drive the plurality of sleeve positioning members to move in a direction away from the base positioning member, so as to release the engagement relationship between the base positioning member and one of the plurality of sleeve positioning members.

Based on the above, the optical fiber module disclosed in the present invention utilizes an elastic telescopic sleeve to be mounted on the optical fiber bundle to provide a bundling and buffering effect on the optical fiber bundle. Then, a clamping claw sleeve is mounted on the elastic telescopic sleeve, and a sleeve is mounted outside the clamping claw sleeve, and finally, a bundling member is placed between the sleeve and the clamping claw sleeve. Moreover, since the aperture of the bundling member at the first end near the end of the optical fiber bundle is smaller, the optical fiber bundle can be gradually tightened through the gradually decreasing aperture of the bundling member, thereby effectively fixing the optical fiber bundle, and by adjusting the depth of the bundling member entering the sleeve, optical fiber bundles of various sizes can be adaptively fixed and bundled, and the degree of tightening of the optical fiber bundle can be adjusted according to needs.

Furthermore, the light source module disclosed in the present invention includes the aforementioned optical fiber module and the light source base, the optical fiber module is disposed in the light source base so that the light beam emitted by the light source can be coupled to the optical fiber bundle via the optical fiber module. The sleeve may include a plurality of sleeve positioning members disposed on its outer surface, and the base of the light source base further includes corresponding base positioning members, so that the base positioning member can be engaged with one of the sleeve positioning members to fix the distance between the optical fiber bundle and the light source. Therefore, the optical fiber module disclosed in the present invention can adaptively fix and bundle optical fiber bundles of various sizes, and can adjust the tightness of the optical fiber bundle according to needs without causing damage to the optical fiber bundle. The light source module using this optical fiber module can easily adjust and fix the distance between the optical fiber bundle and the light source to improve the assembly convenience and accuracy of the light source module.

Please refer to FIG1 and FIG2 simultaneously. In some embodiments, the fiber optic module 100 includes a fiber optic bundle 110, an elastic expansion sleeve 120, a clamping claw sleeve 130, a sleeve 140 and a bundle 150. In some embodiments, the optical fiber module 100 is used to firmly clamp the optical fiber bundle 110 to couple the optical fiber bundle 110 to the light source and to adjust and fix the light guiding distance between the optical fiber bundle 110 and the light source, and the light source module (such as the light source module 10 shown in Figures 5 to 7) using the optical fiber module 100 is used to transmit the light beam emitted from the light source (such as the light source 220 shown in Figures 5 to 7) through the optical fiber bundle 110. In this embodiment, the optical fiber module 100 can be used for optical fiber transmission of a laser beam emitted from a semiconductor laser, that is, the light source of this embodiment may include a laser light source, but the present disclosure is not limited thereto.

FIG3 is a cross-sectional schematic diagram of an optical fiber module according to an embodiment of the present disclosure. Referring to FIG1 and FIG3, in some embodiments, an elastic expansion sleeve 120 is sleeved on the optical fiber bundle 110. The elastic expansion sleeve 120 can be made of elastic materials such as rubber, and can be sleeved on the optical fiber bundle 110 to clamp the optical fiber bundle 110 and provide a buffering effect at the same time to prevent the optical fiber bundle 110 from being over-clamped to cause damage to the optical fiber bundle 110. In this embodiment, the elastic expansion sleeve 120 includes a plurality of annular grooves 122, which surround the elastic expansion sleeve 120 at intervals. As shown in FIG3 , the depth of the annular groove 122 is substantially less than the thickness of the side wall of the elastic expansion sleeve 120. In other words, the annular groove 122 does not penetrate the entire side wall of the elastic expansion sleeve 120 but is only a groove surrounding the elastic expansion sleeve 120. In this way, the annular groove 122 can further provide the elastic expansion sleeve 120 with a degree of expansion in the long axis direction A1 of the elastic expansion sleeve 120.

In this embodiment, the elastic expansion sleeve 120 may further include a plurality of longitudinal grooves 124, which extend along the long axis direction A1 of the elastic expansion sleeve 120. As shown in FIG. 1 , the longitudinal grooves 124 may extend along the long axis direction A1 of the elastic expansion sleeve 120, and may be arranged alternately with each other along the long axis direction A1. In this embodiment, the longitudinal grooves 124 may penetrate the entire side wall of the elastic expansion sleeve 120. In this way, the longitudinal grooves 124 may further provide the elastic expansion sleeve 120 with a degree of expansion in the short axis direction (perpendicular to the long axis direction A1) of the elastic expansion sleeve 120.

1 and 3, in some embodiments, the clamping claw sleeve 130 is sleeved on the elastic telescopic sleeve 120 and includes a plurality of clamping claws 132, which are respectively disposed at the ends of the clamping claw sleeve 130 to clamp the elastic telescopic sleeve 120. In this embodiment, the material of the clamping claw sleeve 130 may include metal, plastic or other slightly elastic materials. The sleeve 140 is sleeved outside the clamping claw sleeve 130 to serve as an outer cover of the optical fiber module 100.

2 and 3 , in some embodiments, the clustering member 150 is located between the sleeve 140 and the clamping claw sleeve 130, and may include a first end 152 and a second end 154 opposite to each other, wherein the first end 152 of the clustering member 150 is close to the end (incident end face) 112 of the optical fiber bundle 110, and the aperture D1 of the first end 152 is substantially smaller than the aperture D2 of the second end 154. In other words, the aperture D1 of the clustering member 150 at the first end 152 closer to the end 112 of the optical fiber bundle 110 is smaller, so as to produce a tightening effect on the optical fiber bundle 110. Specifically, the aperture of the clustering member 150 gradually increases from the first end 152 to the second end 154. In this embodiment, the outer surface of the bundle 150 may further include threads 156, and the bundle 150 is rotated to be screwed into the sleeve 140 in a direction away from the end 112 of the optical fiber bundle 110.

FIG4 is a three-dimensional schematic diagram of an optical fiber module according to an embodiment of the present disclosure. Please refer to FIG3 and FIG4 at the same time. Under such a structural configuration, the optical fiber module 100 can be assembled by, for example, firstly putting the elastic expansion sleeve 120 on the optical fiber bundle 110 near the end 112, then putting the clamping claw sleeve 130 on the elastic expansion sleeve 120, and putting the sleeve 140 outside the clamping claw sleeve 130, and finally using the thread 156 on the outer surface of the clustering member 150 to rotate the clustering member 150 between the sleeve 140 and the clamping claw sleeve 130. The aperture D1 of the first end 152 near the end 112 of the optical fiber bundle 110 is smaller, so when the bundling member 150 is gradually screwed into the sleeve 140, the optical fiber bundle 110 is gradually tightened through the gradually decreasing aperture of the bundling member 150, thereby effectively fixing the optical fiber bundle 110, and by adjusting the depth of the bundling member 150 screwed into the sleeve 140, optical fiber bundles 110 of various sizes can be adaptively fixed and bundled, and the tightening degree of the optical fiber bundle 110 can be adjusted according to needs. Furthermore, the optical fiber module 100 disclosed herein utilizes the gradually decreasing aperture of the bundling member 150 to gradually apply pressure to the clamping claw sleeve 130, so that the clamping claws 132 at the ends of the clamping claw sleeve 130 gradually clamp the optical fiber bundle 110 through the elastic expansion sleeve 120, thereby preventing the optical fiber bundle 110 from being damaged by excessive stress concentration during the bundling process.

FIG. 5 to FIG. 7 are schematic diagrams of a light source module in different usage scenarios according to an embodiment of the present disclosure. It must be noted here that the optical fiber module 100 of FIG. 6 is shown in the form of a cross-sectional view to present the internal structure of the optical fiber module 100. The optical fiber module 100 disclosed in the above-mentioned embodiment can be applied to the light source module 10 of this embodiment. Please refer to FIG. 5 to FIG. 7 at the same time. In this embodiment, the light source module 10 may include the optical fiber module 100 and the light source base 200 disclosed in the above-mentioned embodiment. In this embodiment, the structure of the optical fiber module 100 may be roughly the same as or similar to the above-mentioned embodiment, and the sleeve 140 of the optical fiber module 100 may further include a plurality of sleeve positioning members 142 disposed on the outer surface of the sleeve 140, which are arranged along the long axis direction A1 of the optical fiber bundle 110. The light source base 200 may include a base 210 and a light source 220 disposed in the base 210 . The optical fiber module 100 is disposed in the light source base 200 , so that the light beam emitted by the light source 220 can be transmitted to the optical fiber bundle 110 via the optical fiber module 100 .

In this embodiment, the inner side surface of the base 210 includes a base positioning member 212. The optical fiber module 100 is disposed in the light source base 200, and the base positioning member 212 is suitable for engaging with one of the sleeve positioning members 142 of the sleeve 140 to fix the distance between the optical fiber bundle 110 and the light source 220. In this embodiment, the sleeve positioning member 142 can be a plurality of teeth, and the base positioning member 212 is a protrusion suitable for engaging between two adjacent teeth. Of course, the present disclosure does not limit the structural form of the sleeve positioning member 142 and the base positioning member 212. In one embodiment, the sleeve 140 may further include an adjusting member 144, which is disposed on the outer surface of the sleeve 140 and is suitable for being pressed by an external force to drive the plurality of sleeve positioning members 142 to move away from the base positioning member 212 to release the engagement relationship between the base positioning member 212 and the sleeve positioning member 142.

Specifically, the adjusting member 144 can be a cantilever structure, one end of which is fixed to the sleeve 140, and the cantilever end can be subjected to force to be relatively close to or away from the sleeve 140, and the sleeve positioning member 142 is arranged on this adjusting member 144. Therefore, when the adjusting member 144 is pressed by external force, the sleeve positioning member 142 thereon can be driven to move away from the base positioning member 212 (towards the inside of the sleeve 140) to release the engagement relationship between the base positioning member 212 and the sleeve positioning member 142, so that the optical fiber module 100 can move relative to the light source base 200 to freely adjust the distance between the optical fiber bundle 110 and the light source 220.

Specifically, when the user wants to place the optical fiber module 100 in the light source base 200, the user only needs to move the optical fiber module 100 along the longitudinal direction A1 toward the light source 220 to a position. At this time, the base positioning member 212 will engage with the sleeve positioning member 142 at the corresponding position, thereby fixing the distance between the optical fiber bundle 110 and the light source 220. When the user wants to adjust the relative position between the optical fiber module 100 and the light source base 200, he only needs to apply an external force F1 to the adjusting member 144 of the sleeve 140 as shown in FIG. 6, so that the adjusting member 144 drives the sleeve positioning member 142 thereon to move away from the base positioning member 212, thereby releasing the engagement relationship between the base positioning member 212 and the sleeve positioning member 142, so that the optical fiber module 100 can move freely relative to the light source base 200 to adjust the distance between the optical fiber bundle 110 and the light source 220 ( For example, after adjusting the distance d1 as shown in FIG. 6 to the distance d2 as shown in FIG. 7 to the desired position, the user only needs to stop applying external force to the adjusting member 144 of the sleeve 140, and allow the adjusting member 144 of the sleeve 140 to return to the initial position in the direction of approaching the base positioning member 212 by its elastic restoring force. Then, the base positioning member 212 engages with the sleeve positioning member 142 at the corresponding position, and the optical fiber module 100 can be fixed at the desired position, thereby fixing the distance between the optical fiber bundle 110 and the light source 220.

In summary, the optical fiber module disclosed in the present invention utilizes an elastic expansion sleeve to be mounted on the optical fiber bundle to provide a bundling and buffering effect on the optical fiber bundle. Then, a clamping claw is mounted on the elastic expansion sleeve, and a sleeve is mounted outside the clamping claw sleeve. Finally, a bundling piece is placed between the sleeve and the clamping claw sleeve. Moreover, since the aperture of the bundling piece at the first end near the end of the optical fiber bundle is smaller, the optical fiber bundle can be gradually tightened through the gradually decreasing aperture of the bundling piece, thereby effectively fixing the optical fiber bundle. Moreover, by adjusting the depth of the bundling piece entering the sleeve, optical fiber bundles of different sizes can be adaptively fixed and bundled, and the degree of tightening of the optical fiber bundle can be adjusted according to needs.

Furthermore, the light source module disclosed in the present invention includes the aforementioned optical fiber module and the light source base, the optical fiber module is disposed in the light source base so that the light beam emitted by the light source can be transmitted to the optical fiber bundle via the optical fiber module. The sleeve may include a plurality of sleeve positioning members disposed on its outer surface, and the base of the light source base further includes corresponding base positioning members, so that the base positioning member can be engaged with one of the sleeve positioning members to fix the distance between the optical fiber bundle and the light source. Therefore, the optical fiber module disclosed in the present invention can adaptively fix and bundle optical fiber bundles of various sizes, and can adjust the tightness of the optical fiber bundle according to needs without causing damage to the optical fiber bundle. The light source module using this optical fiber module can easily adjust and fix the distance between the optical fiber bundle and the light source to improve the assembly convenience and accuracy of the light source module.
