AI Technical Summary
When existing special-shaped light strips emit light, it is difficult to obtain a good uniform light effect due to the short light propagation path of light, resulting in uneven light bead arrangement projection on the luminous surface.
A flexible lamp strip is designed to reflect the light emitted from the light surface on the lamp strip using reflection, extending the light propagation path, increasing the distance when the light passes through the uniform part, thereby achieving a better uniform effect.
By extending the light propagation path and increasing the distance of light passing through the uniform part, the flexible light strip can obtain a better uniform effect, avoiding the appearance of lamp bead arrangement projection, and adapting to different product structures and luminous surface shapes.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field related to light strips, and particularly relates to a flexible light strip and a medical device. Background Art
[0002] The special-shaped light strip made by the method of opening a silicone extrusion mold can obtain a better and more uniform light-emitting effect, reduce the non-light-emitting surface silicone on the front, and can be adapted to more structural shapes, so it is widely used in medical devices. The above special-shaped light strip has a better appearance effect, fewer splicing seams, and smaller deformation compared with the acrylic light strip; compared with the conventional silicone light strip, it can better adapt to the structure, is more convenient for disassembly and assembly, has a more uniform light-emitting effect, and can make a narrower light-emitting surface.
[0003] At present, the special-shaped light strip with a front light-emitting effect usually uses a silicone light strip with a conventional square shape of 4.3mm×6mm size stuffed into the gap to emit light, and is made by extrusion using a general mold, and the size of its light-emitting surface cannot be adjusted. However, since the distance of the semi-transparent silicone that the light from the light bar source has to pass through is short, it is difficult to obtain a good light homogenization effect, so that the uneven arrangement projection of the lamp beads is easily seen on the light-emitting surface of the special-shaped light strip. Summary of the Utility Model
[0004] In view of this, it is necessary to provide a flexible light strip and a medical device for solving the above technical problems.
[0005] A flexible light strip is installed on a medical device. The flexible light strip includes:
[0006] A housing having a reflective surface and a light outlet;
[0007] A light bar is disposed in the housing. The light bar has a light-emitting surface, the light-emitting surface is disposed facing the reflective surface, and the light emitted from the light-emitting surface towards the reflective surface can be emitted from the light outlet after being reflected by the reflective surface;
[0008] All the light generated when the light bar works is emitted towards the reflective surface, and the light is emitted from the light outlet after being reflected by the reflective surface;
[0009] A light homogenizing member is disposed on the propagation path of the light, and the light homogenizing member can perform light homogenization processing on the light passing through the light homogenizing member.
[0010] It can be understood that by using a reflective surface to reflect the light emitted from the light-emitting surface of the light bar, the light-emitting operation during the operation of the flexible light strip is realized. This can extend the propagation path of the light within the flexible light strip, enabling the flexible light strip to extend the distance that the light passes through the light homogenizing member and achieving a better light homogenizing effect, so that the arrangement projection of the lamp beads on the light bar cannot be seen on the light-emitting surface of the light outlet when the flexible light strip is operating.
[0011] In one embodiment, the housing includes a first cavity and a second cavity that are communicatively arranged. The second cavity is disposed outside the first cavity and is in communication with the first cavity.
[0012] Among them, the light bar and at least part of the reflective surface are disposed in the first cavity, and the light outlet is disposed on the second cavity.
[0013] It can be understood that through the above structural arrangement, the light bar in the flexible light strip is not in the opening direction of the light outlet, so that the arrangement projection of the lamp beads on the light bar cannot be seen on the light-emitting surface of the light outlet when the flexible light strip is operating.
[0014] In one embodiment, the light bar is abutted against the cavity wall of the first cavity, and the light bar is in contact with the light homogenizing member.
[0015] It can be understood that by using the light homogenizing member to press and limit the light bar against the cavity wall of the first cavity, the light bar can be assembled and limited through the housing and the light homogenizing member, which is convenient for the assembly of the light bar in the flexible light strip.
[0016] In one embodiment, the outer diameter of the light outlet is greater than or equal to the outer diameter of the second cavity.
[0017] It can be understood that through the above structural arrangement, the light-emitting surface of the light outlet when the flexible light strip is operating is in a non-edge shape, which can further improve the light-emitting effect presented when the flexible light strip is operating.
[0018] In one embodiment, the light homogenizing member includes a first light homogenizing portion and a second light homogenizing portion. The first light homogenizing portion is disposed in the first cavity, and the second light homogenizing portion is disposed in the second cavity.
[0019] Among them, the light can sequentially pass through the first light homogenizing portion and the second light homogenizing portion and then be emitted.
[0020] In one embodiment, the reflective surface is covered by the first light homogenizing portion.
[0021] On the propagation path of the light, a cavity is formed on the first light homogenizing portion.
[0022] It can be understood that by using the cavity formed in the first light homogenizing part, the propagation distance of light in the first light homogenizing part can be adjusted. In this way, on the basis of ensuring the light homogenizing effect of the first light homogenizing part, the material consumption of the light homogenizing part can be reduced.
[0023] In one embodiment, a receiving cavity is formed inwardly in the second cavity, and the receiving cavity is filled with the second light homogenizing part.
[0024] In one embodiment, the reflective surface is in the shape of an inclined plane.
[0025] It can be understood that configuring the reflective surface as an inclined plane structure can simplify the structure of the reflective surface, so as to facilitate the processing and formation of the reflective surface on the housing.
[0026] In one embodiment, the material of the housing and / or the material of the light homogenizing part is configured as silica gel.
[0027] In addition, the present application also claims protection for a medical device, including a device main body and the flexible light strip described above, and the flexible light strip is installed on the device main body.
[0028] Due to the application of the above technical solutions, the present utility model has the following advantages compared with the prior art:
[0029] For the flexible light strip and the medical device claimed by the present application, the light emitted from the light-emitting surface of the lamp strip is reflected by the reflective surface to realize the light-emitting operation when the flexible light strip works. In this way, the propagation path of light in the flexible light strip can be extended, so that the flexible light strip can extend the distance that the light passes through the light homogenizing part and make the light obtain a better light homogenizing effect, so that the arrangement projection of the lamp beads on the lamp strip cannot be seen on the light-emitting surface of the light outlet when the flexible light strip works; moreover, the flexible light strip can also adapt to different product structures by means of customizing the shape through mold opening, and obtain light-emitting surface shapes of different sizes and shapes through mold opening.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model are only for the purpose of describing specific embodiments, and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0037] The flexible light strip 100 claimed in this application is installed on a medical device. Specifically, the flexible light strip 100 can be bent into a circular ring and installed on a magnetic resonance device or a computed tomography device in an embedded manner.
[0038] Such as Figures 1 to 4As shown in the figure, a flexible light strip 100 provided by an embodiment of the present application includes a housing 10, a light bar 20, and a light homogenizing member 30. The housing 10 has a reflective surface 101 and a light outlet 102. The light bar 20 is disposed inside the housing 10. The light bar 20 has a light-emitting surface 21, and the light-emitting surface 21 faces the reflective surface 101. The light emitted from the light-emitting surface 21 to the reflective surface 101 can be emitted from the light outlet 102 after being reflected by the reflective surface 101. The light homogenizing member 30 is disposed on the light propagation path, and the light homogenizing member 30 can homogenize the light passing through the light homogenizing member 30. That is to say, the light generated when the light bar 20 in the flexible light strip 100 of the present application works is emitted outward from the light outlet 102 after being reflected by the reflective surface 101. During this process, the light homogenizing member 30 can homogenize the passing light. Of course, when the light homogenizing member 30 is not disposed in the housing 10, the flexible light strip 100 can also emit light outward from the light outlet 102 when working, but the light homogenizing effect of the emitted light is a bit poor. It should be noted that lamp beads (not shown in the figure) are integrated on the light bar 20, so that the light bar 20 can emit light toward the reflective surface 101 after being powered on.
[0039] It can be understood that the flexible light strip 100 of the present application uses the reflective surface 101 to reflect the light emitted from the light-emitting surface 21 of the light bar 20 to achieve the light-emitting operation when the flexible light strip 100 works. This can extend the propagation path of the light in the flexible light strip 100, so that the flexible light strip 100 can extend the distance of the light passing through the light homogenizing member 30 and make the light have a better light homogenizing effect, so that the arrangement projection of the lamp beads on the light bar 20 cannot be seen on the light-emitting surface of the light outlet 102 when the flexible light strip works. In addition, the flexible light strip 100 can also adapt to different product structures by customizing the shape through mold opening, and obtain light-emitting surface shapes of different sizes and shapes through mold opening.
[0040] In some embodiments, the material of the housing 10 and / or the material of the light homogenizing member 30 are configured as silicone. Specifically, the housing 10 can be configured as white silicone, which has a reflective effect, so that the housing 10 can directly reflect the light by the inner wall of the housing 10. The light homogenizing member 30 is configured as semi-transparent silicone and can homogenize the light passing through the light homogenizing member 30.
[0041] Such as Figures 1 to 4As shown, the housing 10 includes a first cavity 11 and a second cavity 12 which are connected in communication. The second cavity 12 is disposed outside the first cavity 11 and communicates with the first cavity 11. Among them, the light bar 20 and at least part of the reflective surface 101 are disposed in the first cavity 11, and the light outlet 102 is disposed on the second cavity 12. So that the light bar 20 in the flexible light strip 100 is not in the opening direction of the light outlet 102, which can ensure that the arrangement projection of the lamp beads on the light bar 20 cannot be seen on the light-emitting surface of the light outlet 102 when the flexible light strip 100 works. Here, both the first cavity 11 and the second cavity 12 are square, and the reflective surface 101 is entirely disposed in the first cavity 11. And, the first cavity 11 and the second cavity 12 are integrally connected.
[0042] As Figures 1 to 4 shown, in some embodiments, the light bar 20 is abutted against the cavity wall 111 of the first cavity 11, and the light bar 20 is in contact with the light homogenizing member 30. That is to say, the light bar 20 can be assembled and limited by the cavity wall 111 of the first cavity 11 in the housing 10 with the light homogenizing member 30, which is convenient for the assembly of the light bar 20 in the flexible light strip 100. When the flexible light strip 100 is produced and prepared, the light bar 20 can be first placed into the extrusion die, and then silicone is injected into the extrusion die to finally form the housing 10 and the light homogenizing member 30. Of course, in other embodiments, the light bar 20 can also be fixed to the cavity wall 111 of the first cavity 11 by means of pasting.
[0043] As Figures 1 to 4 shown, in some embodiments, the light homogenizing member 30 includes a first light homogenizing portion 31 and a second light homogenizing portion 32. The first light homogenizing portion 31 is disposed in the first cavity 11, and the second light homogenizing portion 32 is disposed in the second cavity 12. Among them, light can sequentially pass through the first light homogenizing portion 31 and the second light homogenizing portion 32 and then be emitted. Here, the first light homogenizing portion 31 and the second light homogenizing portion 32 are integrally connected. Of course, in other embodiments, the first light homogenizing portion 31 and the second light homogenizing portion 32 can also be configured as two separate individuals.
[0044] As Figures 1 to 4 shown, in some embodiments, the reflective surface 101 is covered by the first light homogenizing portion 31. On the light propagation path, a cavity 311 is formed in the first light homogenizing portion 31, so that the propagation distance of light in the first light homogenizing portion 31 can be adjusted. In this way, on the basis of ensuring the light homogenizing effect of the first light homogenizing portion 31 on light, the material consumption of the light homogenizing member 30 can be reduced. It should be noted that the shape of the cavity 311 in the first light homogenizing portion 31 can be specifically set according to the usage requirements and will not be elaborated here. Of course, in other embodiments, the first light homogenizing portion 31 may not be provided with the cavity 311, and specifically, the first light homogenizing portion 31 fills all the spaces in the first cavity 11 except the light bar 20.
[0045] AsFigures 1 to 4 As shown, in some embodiments, a receiving cavity 121 is formed inwardly in the second cavity 12, and the receiving cavity 121 is filled with the second light homogenizing portion 32. That is to say, the second light homogenizing portion 32 covers the light outlet 102 on the second cavity 12 for light to emit. Here, the receiving cavity 121 is conical. Of course, in other embodiments, the second light homogenizing portion 32 may also only fill all or part of the space in the second cavity 12 for light to emit.
[0046] As Figures 1 to 4 shown, in some embodiments, the outer diameter of the light outlet 102 is greater than or equal to the outer diameter of the second cavity 12. Here, the light outlet 102 is covered by the light homogenizing member 30, specifically by the second light homogenizing portion 32 of the light homogenizing member 30. When the flexible light strip 100 works, the light emitting surface of the light outlet 102 is in a non-edge shape, which can further improve the light emitting effect presented when the flexible light strip 100 works.
[0047] As Figures 1 to 4 shown, in some embodiments, the reflecting surface 101 is inclined, which can simplify the structure of the reflecting surface 101 to facilitate the processing and formation of the reflecting surface 101 on the housing 10. Of course, in other embodiments, the reflecting surface 101 may also be concave, convex, or other irregular shapes, as long as it is ensured that the light reflected by the reflecting surface 101 can be emitted outward from the light outlet 102, and no further elaboration will be made here.
[0048] The flexible light strip can also adapt to different product structures in the form of customizing the shape by mold opening, and obtain light emitting surface shapes of different sizes and shapes through mold opening.
[0049] As Figures 1 to 4 shown, the present application also provides a medical device, including a device main body 200 and the flexible light strip 100 described above, and the flexible light strip 100 is installed on the device main body 200. Here, an installation groove 210 is formed on the device main body 200, and the flexible light strip 100 can be fixed to the installation groove 210 of the device main body 200 in a glued manner by an adhesive such as 3M tape.
[0050] As Figure 5 shown, in some embodiments, a cover plate 220 is installed on the device main body 200, and the cover plate 220 partially covers the installation groove 210 on the device main body 200. Specifically, the end surface of the cover plate 220 away from the device main body 200 can be set in the same plane as the plane where the light outlet 102 of the flexible light strip 100 is located, which can further improve the light emitting effect presented when the flexible light strip 100 is assembled to the device main body 200. Here, the cover plate 220 is configured as an acrylic plate.
[0051] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.
[0052] Those of ordinary skill in the art of this technology should recognize that the above embodiments are only used to illustrate the present utility model, rather than to limit the present utility model. As long as appropriate changes and variations made to the above embodiments fall within the scope of the spirit of the present utility model, they fall within the scope of protection required by the present utility model.
