Description

Technical Field

[0001] The utility model relates to the technical field of optical equipment, in particular to an optical component and an optical equipment. Background Art

[0002] It is recognized that irradiating the skin with light sources of specific wavelengths is beneficial. For example, red light with a wavelength of 650nm has been shown to be used to stimulate hair follicles to achieve the effect of hair growth or preventing hair loss.

[0003] This type of device that uses a light source to irradiate light to a specific part of the human body needs to use a flexible circuit board that is easy to bend or shape to carry the above-mentioned light source. However, due to the poor rigidity of the flexible circuit board itself, it cannot form an ideal optical surface after being shaped or bent, resulting in the circuit board having poor flatness when it needs to be at least partially exposed, and cannot provide the user with better visual improvement. Moreover, since the formed optical surface is not ideal, the irradiation effectiveness of the light emitted by the light source is further affected. Utility Model Content

It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0080] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0081] The utility model provides an optical component and an optical device, such as Figure 1-Figure 24 The optical assembly includes a housing 200, a flexible circuit substrate 100 and a light source assembly, and the light source assembly includes a light emitting element 130 to solve the problem that the flexible circuit substrate 100 is inconvenient to install and thus affects the irradiation effect of the light source assembly. Detailed description is given below through embodiments.

[0082] Embodiment 1: Flexible circuit substrate.

[0083] The utility model provides a flexible circuit substrate, such as Figure 1-Figure 3As shown, the flexible circuit substrate 100 includes a base portion 110 and a belt portion 120, the belt portion 120 includes a plurality of belt portions 121, the plurality of belt portions 121 are respectively extended from the base portion 110 toward a direction away from the base portion 110, and the extension directions of the plurality of belt portions 121 are different from each other; an opening area 122 is provided between the belt portion edges 1210 of two adjacent belt portions 121, and the opening area 122 has an opening characteristic, and the opening characteristic includes:

[0084] The opening width of the opening region 122 gradually increases in a direction away from the base portion 110 .

[0085] The flexible circuit substrate 100 provided by the utility model has a plurality of strip portions 121 extending from the base portion 110 in a direction away from the base portion 110, and the extension directions of the plurality of strip portions 121 are different from each other, so that the plurality of strip portions 121 can be relatively flexibly connected to form a flexible circuit substrate with any desired arc surface configuration, which is suitable for the needs of optical devices such as hair growth caps and facial light instruments with specific configurations for flexible circuit substrates; Figure 1 There is an opening area 122 between the edges 1210 of the adjacent strip portions 121 of the two adjacent strip portions 121. The opening width of the opening area 122 gradually increases from the base portion 110 toward the direction away from the base portion 110, so that after the two adjacent strip portions 121 are connected to each other to form an arc-shaped spherical structure, it is not easy to have obvious folds or local bulges in the edge areas of the two adjacent strip portions 121, and the arc surface configuration is more uniform and consistent, thereby ensuring that the flexible circuit substrate can form a structure with a flatter arc surface configuration.

[0086] In some embodiments, the base portion 110 and the belt portion 120 of the flexible circuit substrate can be an integral structure (eg, Figure 1 ), for example, a whole sheet of PCB flexible circuit board, which is cut in the area outside the base part 110 by cutting to obtain multiple strips 121 and the opening area 122 between the strips 121; in other embodiments, the base part 110 and the strip part 120 can also be a combined structural part, for example, the base part 110 is an independently arranged flexible load-bearing member, and the multiple strips 121 are arranged in sequence around the edge of the base part 110 and combined with the base part 110 to form a desired configuration. Here, the connection form between the multiple strips 121 and the base part 110 includes but is not limited to at least one or any combination of gluing, welding, sewing and attachment of connectors. For the convenience of description, in the following embodiments, the base part 110 and the strip part 120 are cut and formed as an integral structural part, and the strip part 120 is arranged circumferentially around the base part 110.

[0087] In some embodiments, in a direction from the base portion 110 toward away from the base portion 110 , the opening region 122 has a root opening 1221 and an end opening 1222 , and an opening width of the root opening 1221 is smaller than an opening width of the end opening 1222 .

[0088] like Figure 2 As shown, the extension directions of the plurality of strip-shaped portions 121 are different, so the extension lengths of the opening areas 122 between two adjacent strip-shaped portions 121 are also different. Each opening area 122 has an opening width that gradually increases from the root opening 1221 to the end opening 1222 in the extension direction. The setting of the root opening 1221 is conducive to the overlapping connection of two adjacent strip-shaped portions 121, and the edge areas of the two adjacent strip-shaped portions 121 after the overlapping connection are not prone to obvious folds or local bulges, and the arc surface configuration is more uniform. Preferably, the width of the root opening 1221 is less than 1 mm. The smaller the width of the root opening 1221, the easier it is for the two adjacent strip-shaped portions 121 to be relatively close when overlapping and connected, and the roots of the two adjacent strip-shaped portions 121 can overlap by approaching a smaller distance and angle. Generally, the width of the root opening 1221 is not less than 0.5 mm, so as to facilitate the cutting process between the plurality of strip-shaped portions 121.

[0089] In some embodiments, the strip edges 1210 of two adjacent strips 121 are provided with an arc-shaped hole 1223 at the root opening 1221 , the arc section of the arc-shaped hole 1223 protrudes toward one side of the base portion 110 , and the arc-shaped hole 1223 is connected to the root opening 1221 .

[0090] like Figure 2, an arc-shaped hole 1223 is provided at the root opening 1221, and the arc-shaped hole 1223 is connected to the root opening 1221, that is, connected to the opening area 122, so that the opening area 122 can be obtained by cutting between two adjacent strip-shaped parts 121, and the cutting can be in the form of integral stamping or blade cutting. It should be emphasized that the arc-shaped hole 1223 can prevent excessive cutting during the cutting process, and the first step of the processing process is to punch out a plurality of circular holes on the flexible circuit substrate first, and the second step is to perform the above-mentioned cutting based on the positioning of the circular holes, including but not limited to integral stamping or blade cutting, and the opening area 122 formed by the cutting is connected to the circular hole, so that the final configuration is formed with the arc-shaped hole 1223 and the opening area 122 connected to the arc-shaped hole 1223, that is, the arc-shaped hole 1223 is obtained by integral stamping or blade cutting of the aforementioned circular hole. Here, the circular hole in the first step of the processing technology provides a positioning function to facilitate subsequent cutting; traditionally, flexible circuit substrates such as PCBs are made of materials with a certain rigidity, and the rigid material has a predetermined and relatively uniform thickness. The rigidity of the flexible circuit substrate makes it easier to cause the circuit substrate to tear at the root opening 1221 when it is cut by punching or blade cutting. In this embodiment, the circular hole has a continuous arc-shaped inner edge, so it can effectively prevent the tearing problem caused by cutting when it is punched or cut by blade. When the two strips 121 overlap, the arc hole 1223 formed by the circular hole after processing increases the overlapping deformation at the root opening 1221, so that after the two strips 121 overlap, the area around the arc hole 1223 will not produce visible and obvious folds or local bulges. It can be understood that the diameter of the arc hole 1223 can be close to the minimum width of the root opening 1221, and then the root opening 1221 is connected through the semicircular hole. When an arc-shaped hole with a smaller diameter is provided, it has a shorter arc-shaped inner edge, which can make the adjacent strip portions 121 have an imperceptible hole shape after being connected, thereby making the product configuration more integrated and enhancing the user's visual perception.

[0091] In some embodiments, the arc-shaped hole 1223 is a primary arc hole, and both ends of the primary arc hole extend to both ends of the root opening 1221 respectively. Both ends of the arc segment of the primary arc hole intersect with the strip edges 1210 of the two adjacent strip portions 121 at the root opening 1221 respectively, and the diameter of the primary arc hole is greater than the opening width of the root opening 1221.

[0092] like Figure 2As shown, the major arc hole is an open hole formed by a part of an arc of a circle with a central angle greater than 180°, and the two ends of the major arc hole are connected with the two ends of the root opening 1221. It should be noted that the major arc hole with a smaller diameter cannot provide a longer arc-shaped inner edge, which makes the overlapping deformation of the two strip-shaped parts 121 no longer sufficient when overlapping, and the peripheral area of ​​the major arc hole has unpleasant creases and bulges after overlapping; on the contrary, when the major arc hole with a larger diameter is provided, it has a longer arc-shaped inner edge, which brings a more sufficient overlapping deformation, so that the two strip-shaped parts 121 have less obvious creases and less obvious bulges in the peripheral area of ​​the major arc hole after folding or overlapping, but it is less desirable that a hole type that is easier for users to notice is formed after folding, which also reduces the overall unity of the product configuration. Therefore, preferably, the diameter of the primary arc hole is 0.5 mm-10 mm and is greater than or equal to the width of the root opening 1221, so that a more compromising preferred solution can be provided for creases or bulges based on the hole shape after folding.

[0093] In some embodiments, the strip-shaped portion edges 1210 of two adjacent strip-shaped portions 121 can overlap to form an overlapping region 123 , and the overlapping region 123 can close or partially close the opening region 122 between the two adjacent strip-shaped portions 121 .

[0094] See also Figure 3 and Figure 4 On the one hand, when the arc-shaped hole 1223 is overlapped by the strip portion 121, a closed mouth is formed at its opening (i.e., closed), which makes the overlapped arc-shaped hole 1223 become an approximately circular hole configuration. In other words, as the overlapping angle further increases, the hole type can be further closed inward without restriction, which brings a less obvious visible hole type to the overlapping circuit substrate, which is beneficial to the visual unity of the substrate after the overlapping configuration, and can improve the user experience to a certain extent; but it is obvious that with further inward closure, the peripheral area of ​​the approximately circular hole formed by the arc-shaped hole 1223 will have more obvious folds or bulges, so the degree of inward overlap needs to be limited, but can be partially allowed.

[0095] See also Figure 5On the other hand, when the arc hole 1223 is overlapped by the strip portion 121, a non-closed opening is formed at its opening so that the root opening 1221 is visible (i.e., partially closed), and the overlapped arc hole 1223 is not configured as an approximately circular hole. In other words, with the overlap of the strip portion 121, the arc hole 1223 can be formed into a non-closed opening, and the root opening 1221 reserves the "triangle" opening shape shown in the figure, which brings a smaller folding deformation to the circuit substrate after the overlapping connection, which is conducive to less obvious folds or bulges in the surrounding area of ​​the arc hole 1223 and the edge area of ​​the strip portion 121 after the overlapping configuration of the substrate; but it is obvious that with the presentation of the non-closed opening, a more easily noticeable visible opening is brought about, that is, the combination of the arc hole 1223 and the above-mentioned "triangle" opening shape, which is not conducive to the improvement brought to the user after the final overlapping configuration, so the degree of outward overlap also needs to be limited, but it can be partially allowed.

[0096] In the above embodiment, the overlapping adjacent strip portions 121 can be connected by gluing, welding, sewing, or any combination of connecting member attachments. The connecting member attachment can be a tape 124 adhered to the outside (such as Figure 8 ).

[0097] like Figure 3 The strip-shaped portion 121 has overlapping portions reserved at the strip-shaped portion edges 1210 on both sides along the extension direction X1 thereof. The strip-shaped portion edge 1210 of one strip-shaped portion 121 is crimped to the other strip-shaped portion to form an overlapping area 123. The overlapping area 123 at least closes a portion of the opening area 122, thereby achieving at least partial connection of the strip-shaped portion 121 and forming a flexible circuit substrate with a specific configuration. The connection adaptability is good, and according to the specific form of the arc surface configuration required to be formed by the flexible circuit board, the two adjacent strip-shaped portions 121 can form a configuration of the required arc surface structure after overlapping.

[0098] In some embodiments, the percentage of the sum of the surface areas of the overlapping regions 123 formed by the plurality of strip-shaped portions 121 to the total area of ​​the plurality of strip-shaped portions 121 does not exceed 10%.

[0099] It can be understood that the flexible circuit substrate is used to set electrical components such as light sources. If the area of ​​the overlapping area 123 is too large, it will affect the effective area of ​​the setting area of ​​electrical components such as light sources, thereby reducing the utilization rate. If the overlapping area 123 is too small, it will be unfavorable to the stability of the arc surface structure after the overlap. Therefore, the total area of ​​the overlapping area 123 does not exceed 10% of the total area of ​​the multiple strip-shaped parts 121, which can ensure that the basic working area of ​​the strip part 120 can meet the reasonable arrangement of electrical components. For example, for the hair growth cap, a smaller overlapping area can meet the arrangement requirements of at least arranging more than 400 light sources with a base diameter of 5.6 mm in the base part 110 and the strip part 120.

[0100] In some embodiments, when the strip edges 1210 of two adjacent strip portions 121 overlap, an overlapping vertex angle is formed, and the angle of the overlapping vertex angle does not exceed 40°.

[0101] like Figure 4 , the overlapping vertex angle α of the overlapping region 123 is the vertex angle of the overlapping region 123 formed after the strip-shaped portion edges 1210 of two adjacent strip-shaped portions 121 overlap. In some embodiments, among the multiple strip-shaped portion edges 1210 on both sides of the multiple strip-shaped portions 121 along the extension direction thereof, at least one strip-shaped portion edge 1210 is in a curved shape. When the strip-shaped portion edge 1210 of the strip-shaped portion 121 is not a straight line but a curve, the overlapping region 123 is approximately a triangle, that is, the three sides of the triangle are all curves, and the overlapping vertex angle is the vertex angle of the approximate triangle, and the vertex angle is the angle between the tangent lines of the two curves at the vertex.

[0102] When the overlap angle is 0°, Figure 6 As shown, two adjacent strips 121 can be cut more appropriately so that they are close to each other and are in contact at the edge 1210 of the strips after bending, and do not overlap, that is, the overlapping angle is 0. Such a design can ensure that the circuit substrate has a structure located on the same curved surface after bending, that is, there is no overlap between the upper and lower layers, providing a richer implementation scheme. In order to further ensure that the two adjacent strips 121 can be connected, the connection can be achieved by welding, sewing, or a connector attachment, or any combination thereof. The connector attachment can be a tape 124 adhered to the outside.

[0103] When the overlap angle is greater than 0°, Figure 7 The strip edges 1210 of the two strips 121 overlap to form an overlapping area 123. The total area of ​​the overlapping area 123 is less than 10% of the total area of ​​the multiple strips 121, and the overlapping vertex angle α is not greater than 40°, forming an overlapping area 123 that is approximately triangular. The arc-shaped hole 1223 can also be closed well, and the edge areas of the two strips 121 are not prone to obvious folds or local bulges, and the formed arc surface has better flatness. If the overlapping vertex angle is too large, the area around the arc-shaped hole 1223 will produce visible and obvious folds or local bulges, and the area of ​​the overlapping area 123 will increase, affecting the effective use area of ​​the flexible circuit substrate.

[0104] In some embodiments, two adjacent strip portions 121 overlap and bend on the same side to form a flexible circuit substrate with an arc surface configuration. The flexible circuit substrate with an arc surface configuration is conducive to ensuring that the light emitting element 130 on the flexible circuit substrate has a certain adjustable irradiation direction, and different curved arc surfaces can meet the requirements of, for example, a hair growth cap or a facial irradiation instrument for arc surface irradiation.

[0105] In some embodiments, a plurality of strip-shaped portions 121 are overlapped in sequence and bent on the same side to form a flexible circuit substrate having a semi-ellipsoidal shell structure.

[0106] like Figure 8 As shown, when all the strip-shaped portions 121 are bent and connected on the same side in sequence, a flexible circuit substrate with a shell structure is formed. Taking the flexible circuit substrate used in a hair growth cap as an example, the shell structure is a spherical shell or an ellipsoidal shell. The surrounding area where two adjacent strip-shaped portions 121 are connected and the area around the arc-shaped hole 1223 will not produce visible and obvious creases or local bulges. The shell structure has a uniform arc surface both on the inner and outer surfaces, meeting the layout requirements of electrical components. Taking the electrical component as a light source as an example, the arc shell structure can provide a larger number of light source arrangements, thereby effectively improving the irradiation energy of the light source and achieving a better product use effect; generally speaking, the light source is arranged on the flexible circuit substrate vertically relative to the flexible circuit substrate and has a predetermined irradiation area. In theory, the closer the shell structure is to a complete arc surface, the more controllable and stable the energy distribution in the irradiation area is (affected by the arrangement position and density of the light source), that is, a more uniform arc surface can further improve the irradiation effect; in addition, in order to increase the irradiation energy of the light source, there is often no obstruction on the irradiation path of the light source, that is, in the prior art, such electronic products will directly expose the light source to the user's line of sight, that is, the user's perspective can directly observe the entire flexible circuit substrate with a light source arrangement, and the uniform arc surface formed by the above-mentioned improvement can provide an arc surface configuration with the best viewing angle, thereby improving the user experience.

[0107] In some embodiments, two adjacent strip portions 121 are connected by at least one of the following methods: gluing, welding, sewing, and attaching through a connecting member. The connecting member can be an adhesive tape 124, such as Figure 8 .

The opening area 122 between the strip portion edges 1210 of two adjacent first sub-bands 1211 on the same side of the base portion 110 is a first opening area 12201, and the opening characteristics of the first opening area 12201 are first opening characteristics, and the first opening characteristics include:

[0110] The opening width of the first opening area 12201 gradually increases in a direction from the base portion 110 toward a direction away from the base portion 110 .

[0111] For ease of explanation, the first direction is defined as being along the short axis (X-axis) of the base portion 110, the second direction is defined as being along the long axis (Y-axis) of the base portion 110, and the first sub-band 1211 is provided on both sides of the long axis of the base portion 110, i.e., the Y-axis. Unless otherwise specified, the directions of the Y-axis and the X-axis are used as the second direction and the first direction below. It can be understood that in the flexible circuit substrate of this embodiment, the multiple strip-shaped portions 121 only include multiple first sub-bands 1211, and multiple first sub-bands 1211 are provided on both sides of the base portion 110. Among the multiple first sub-bands 1211 on the same side, at least two first sub-bands 1211 can overlap to form a flexible circuit substrate having a curved surface, and when the multiple first sub-bands 1211 on the same side overlap in sequence, a flexible circuit substrate with a shell structure can be formed. A first opening area 12201 and a first arc-shaped hole 12231 are provided between two adjacent first sub-bands 1211, which effectively avoids the more obvious creases or local bulges that may be generated in the peripheral areas of the first sub-band 1211 and the peripheral areas of the first arc-shaped hole 12231 when overlapping, and is conducive to obtaining a flexible circuit substrate with a more uniform arc surface.

[0112] Embodiment three:

[0113] like Fig.10 As shown, the flexible circuit substrate provided in this embodiment includes a base portion 110 and a belt portion 120. The belt portion 120 includes a plurality of belt-shaped portions 121. The plurality of belt-shaped portions 121 include a plurality of first sub-belts 1211. The plurality of first sub-belts 1211 are arranged on both sides of the base portion 110 along a first direction. The extension directions of each first sub-belt 1211 are respectively X0, X1, X2, X3, X4, X5, X6, X7, X8, X9, X10, X11, X12, and X13. At least two first sub-belts 1211 are arranged on each side. In this embodiment, seven first sub-belts 1211 are arranged on each side. Each first sub-belt 1211 extends from the base portion 110 toward a direction away from the base portion 110. It should be emphasized that, unlike the second embodiment, in the Fig.10In the middle viewing angle, the Y axis is the long axis of the base portion 110, the X axis is the short axis of the base portion 110, the long axis is parallel to the second direction, and the short axis is parallel to the first direction. The base portion 110 is provided with two first sub-bands 1211 at both ends along the long axis. Here, when the four strips 121 at the two ends in the extending directions of X10, X11, X12, and X13 are arranged on both sides of the Y axis (not overlapping with the Y axis), they are defined as the first sub-bands 1211. The opening area 122 between the strip edges 1210 of the two adjacent first sub-bands 1211 on the same side of the base portion 110 is the first opening area 12201. The opening characteristics of the first opening area 12201 are the first opening characteristics, and the first opening characteristics include:

[0114] The opening width of the first opening area 12201 gradually increases in a direction from the base portion 110 toward a direction away from the base portion 110 .

[0115] It can be understood that in the flexible circuit substrate of this embodiment, the multiple strip-shaped portions 121 only include multiple first sub-strips 1211, multiple first sub-strips 1211 are arranged on both sides and both ends of the Y axis of the base portion 110, the first sub-strips 1211 at the end of the base portion 110 do not overlap with the Y axis, and among the multiple first sub-strips 1211 on the same side of the Y axis, at least two adjacent first sub-strips 1211 overlap to form a flexible circuit substrate with a curved arc surface, and when the multiple first sub-strips 1211 on the same side of the Y axis overlap in sequence, a flexible circuit substrate with a shell structure approximately in the shape of an ellipsoid can be formed. A first opening area 12201 and a first arc-shaped hole 12231 are arranged between the multiple first sub-strips 1211, which effectively avoids the more obvious folds or local bulges that may be generated in the peripheral areas of the first sub-strips 1211 and the peripheral areas of the first arc-shaped holes 12231 when overlapping, which is conducive to obtaining a flexible circuit substrate with a more uniform arc surface.

[0116] Embodiment 4:

[0117] like Fig.11 As shown, the flexible circuit substrate provided in this embodiment includes a base portion 110 and a band portion 120, the band portion 120 includes a plurality of band portions 121, the plurality of band portions 121 include at least one second sub-band 1212, the second sub-band 1212 is arranged along the Y-axis at at least one end of the base portion 110, the end of the second sub-band 1212 is extended along the Y-axis, the second sub-band 1212 overlaps with the Y-axis of the base portion 110, and the band portion edges 1210 on both sides of the second sub-band 1212 are respectively located on both sides of the Y-axis.

[0118] The second sub-band 1212 extends from the base portion 110 along the Y axis toward a direction away from the base portion 110, and the extension direction is Y1. The opening area 122 between the two side strip edges 1210 of the second sub-band 1212 and the one side strip edge 1210 of the first sub-band 1211 adjacent thereto is a second opening area 12202. The opening characteristics of the second opening area 12202 are second opening characteristics, and the second opening characteristics include:

[0119] The opening width of the second opening area 12202 gradually increases in a direction from the base portion 110 toward a direction away from the base portion 110 .

[0120] It can be understood that in the first embodiment Figure 1 The flexible circuit substrate shown in the figure includes two second sub-bands 1212, and a second sub-band 1212 is respectively arranged at both ends of the base portion 110 along the second direction. Fig.11 In the flexible circuit substrate shown in the figure, only one second sub-band 1212 (extending in the direction Y1) is provided at the lower end of the base portion 110 in the perspective of the figure. The number of the first sub-bands 1211 on both sides of the base portion 110 can be any number of more than two, such as Figure 3 As shown, two first sub-bands 1211 are respectively arranged on both sides of the base portion 110. Fig.11 As shown, six first sub-bands 1211 are arranged on both sides of the base portion 110, which is related to the shape, size and required configuration of the flexible circuit substrate. At the same time, it should be pointed out that in this case, there is a clear division between the first sub-band 1211 and the second sub-band 1212. Fig.11 For example, a flexible circuit substrate includes a base portion 110 and a belt portion 120, the belt portion 120 includes a plurality of belt portions 121, the plurality of belt portions 121 include a plurality of first sub-belts 1211, the plurality of first sub-belts 1211 are arranged on both sides of the Y axis of the base portion 110, and the extension directions of the plurality of first sub-belts 1211 are respectively different from each other, X0, X1, X2, X3, X4, X5, X6, X7, X8, X9, X10, and X11, and each first sub-belt 1211 extends from the base portion 110 to the belt portion 120. The two sub-bands 1211 and 1212 extend in a direction away from the base portion 110. When the strip-shaped portions 121 at the two upper ends in the X10 and X11 directions are arranged on both sides of the Y axis (not overlapping the Y axis), they are defined as the first sub-band 1211, and when the strip-shaped portion 121 in the Y1 direction passes through the Y axis (overlapping the Y axis), it is defined as the second sub-band 1212. Therefore, the second sub-band 1212 is arranged at at least one end of the base portion 110 along the Y axis, and there is only one sub-band 1212 at the end. When the first sub-band 1211 and the second sub-band 1212 overlap each other, the peripheral area of ​​the second arc-shaped hole 12232 and the edge areas of the first sub-band 1211 and the second sub-band 1212 are not prone to obvious folds or bulges.

[0121] In a preferred embodiment, multiple first sub-bands 1211 are symmetrically arranged on both sides of the Y-axis of the base portion 110, and the extension directions (X0, X1, X2, X3, X4, X5, X6, X7, X8, X9, X10, X11) of the multiple first sub-bands 1211 are different. Except for the two middle first sub-bands 1211 whose band edges 1210 are straight, the band edges 1210 of the other first sub-bands 1211 are all curved, and the curvature of the curve increases successively from the middle to both sides, which is beneficial for two adjacent first sub-bands 1211 to simultaneously meet the requirements of the overlapping vertex angle and the area of ​​the overlapping region 123 when overlapping, and it is not easy to have obvious creases or bulges in the edge areas of any two first sub-bands 1211 after overlapping. The arc-shaped hole 1223 between the two first sub-bands 1211 is a first arc-shaped hole 12231, and when the two first sub-bands 1211 overlap, the first arc-shaped hole 12231 provides a folding deformation amount at the root opening 1221, so that after the two first sub-bands 1211 overlap, the area around the first arc-shaped hole 12231 will not produce visible and obvious creases or local bulges, and after the two first sub-bands 1211 overlap, the root opening 1221 adjacent to the first arc-shaped hole 12231 can be closed to form a flexible circuit substrate with a complete shell structure.

[0122] In some embodiments, the base portion 110 has a greater extension length along the major axis than a greater extension width along the minor axis.

[0123] In the present application, the explanation of the base portion 110 is that when the base portion 110 and the belt portion 120 are an integral component (for example, a whole flexible PCB board), the size or shape of the base portion 110 is determined based on the pre-cutting requirements, that is, the base portion 110 does not have a clear visible boundary, but can be defined based on the area enclosed by the circular hole. Fig.11As shown in the example, when the flexible circuit substrate is an integral component, it can be cut into a generally elliptical structure first, and then a plurality of circular holes are punched out at the substrate. Based on the positioning of the positions of these circular holes, cutting is performed, and the cutting forms include but are not limited to integral punching or blade cutting, etc. The opening area 122 formed after cutting is connected to the circular hole, so that the final configuration is an opening area 122 having an arc hole 1223 and connected to the arc hole 1223, that is, the arc hole 1223 is formed by the aforementioned circular hole after integral punching or blade cutting, and the base portion 110 is defined by these circular holes, which is approximately a rectangular area surrounded by these holes and has no clear boundaries. When the base portion 110 and the belt portion 120 are independent components, the base portion 110 can be understood as a flexible component with a clear boundary, which can be connected to the belt portion 120 through a variety of connection forms, including but not limited to one or more combinations of gluing, welding, sewing, and attachment through a connector.

[0124] like Fig.14 As shown, the base portion 110 is in a long strip shape, which is conducive to the multiple first sub-bands 1211 and the multiple second sub-bands 1212 being able to form a flexible circuit substrate with an ellipsoidal shell structure after overlapping in sequence, such as Figure 8 As shown, the ellipsoidal shell structure is easier to match the curve of the head, so as to obtain a flexible circuit substrate with an adaptable head shape and size. In some embodiments, the base portion 110 can also be other geometric shapes, and the corresponding spherical shell or ellipsoidal shell-shaped flexible circuit substrate configuration can also be obtained by extending the lengths and directions of the multiple first sub-bands 1211 and the multiple second sub-bands 1212.

[0125] like Fig.11 In some embodiments, ignoring the spacing between the two second arc-shaped holes 12232 at the edges 1210 of the strip portions on both sides of the second sub-band 1212, the second sub-band 1212 is fan-shaped, where the three sides of the fan-shape are all curves, and the edges 1210 of the strip portions on both sides of the second sub-band 1212 and their end edges enclose a surface that is approximately fan-shaped, which is beneficial for the edges 1210 of the strip portions on both sides of the second sub-band 1212 to overlap with the edges 1210 of the strip portions of the adjacent first sub-band 1211 to obtain a curved arc surface.

[0126] Embodiment 5: Optical component.

[0127] The utility model embodiment provides an optical component, such as Fig.12 , including a light-emitting component 130 and a flexible circuit substrate provided by any one of embodiments 1 to 4 of the present invention, wherein a plurality of light-emitting components 130 are provided, and at least one light-emitting component 130 is distributed in the belt portion 120 of the flexible circuit substrate.

[0128] The optical component provided by the utility model can flexibly connect the multiple strip portions 121 of the belt portion 120 to form an arc surface configuration without obvious folds or bulges. Therefore, the installation position and irradiation direction of the light-emitting component 130 can be adjusted by the multiple strip portions 121, thereby avoiding folds or bulges caused by overlapping and connecting the multiple strip portions 121, which is beneficial to ensuring the irradiation direction and irradiation distance of the light-emitting component 130.

[0129] In some embodiments, at least one light emitting element 130 is distributed on the base portion 110 of the flexible circuit substrate, so that the base portion 110 can also provide light emitting illumination, thereby increasing the distribution area of ​​the light emitting element 130 to meet different needs.

[0130] In some embodiments, the light emitting element 130 is a laser light source or an LED light source. Fig.12 Both the strip portion 121 and the base portion 110 are arranged with a plurality of light emitting elements 130, which can provide multi-area and multi-angle light irradiation.

[0131] Embodiment 6: Optical component;

[0132] like Fig.13 and Fig.14 The optical assembly includes a housing 200, a flexible circuit substrate 100 and a light source assembly, the light source assembly includes a light emitting member 130, the housing 200 has a light-transmitting area 210 and an arc-shaped outer wall, and the outer wall of the housing 200 is provided with a plurality of connecting parts; the flexible circuit substrate 100 includes a base portion 110 and a plurality of strip portions 121 arranged on at least two opposite sides of the base portion 110, the strip portions 121 extend from the base portion 110 toward a direction away from the base portion 110, and the extension directions of the plurality of strip portions 121 are different from each other, and each strip portion 121 has at least one matching portion; the light emitting member 130 is provided on the flexible circuit substrate 100 and arranged toward one side of the housing 200, and the emitted light of the light emitting member 130 can pass through the light-transmitting area 210; wherein the matching portion is matched and connected with the connecting portion and enables the flexible circuit substrate 100 to be tensionedly mounted on the outer wall of the housing 200, and the tensioned flexible circuit substrate 100 drives the light emitting member 130 to abut against the outer wall of the housing 200.

[0133] like Fig.14The housing 200 has a light-transmitting area 210, and each light-emitting element 130 has a fixed end 131 and a light-emitting end 132. The fixed end 131 of the light-emitting element 130 is fixedly connected to the flexible circuit substrate 100. When the flexible circuit substrate 100 is installed on the outer wall of the housing 200, the light-emitting end 132 of the light-emitting element 130 is arranged opposite to the light-transmitting area 210 on the housing 200 to provide outgoing light. The multiple strip-shaped portions 121 of the flexible circuit substrate 100 can form a shell structure adapted to the housing 200 after overlapping and bending. The light-emitting element 130 is arranged on the side of the flexible circuit substrate 100 facing the housing 200. When installed, the light-emitting end 132 of the light-emitting element 130 faces the housing 200 and faces the light-transmitting area 210, so that the outgoing light passes through the housing 200 to irradiate the required light, meeting the needs of the user. Among them, the housing 200 can provide a stable support for the flexible circuit substrate 100, and can selectively transmit the outgoing light through the light-transmitting area 210. The flexible circuit substrate 100 is tensionedly installed on the shell 200, so that the flexible circuit substrate 100 can achieve an ideal flatness, which can provide a visual improvement for the user. The light emitting end 132 of the light emitting component 130 can abut against the outer wall of the shell 200, thereby ensuring that the light emitting end 132 of the light emitting component 130 can better fit the outer wall of the shell 200 to form a continuous light emitting surface. For example, the outer wall of the shell 200 is a complete and continuous arc-shaped surface, and the multiple light emitting components 130 matched therewith can form an optical surface suitable for the outer wall structure of the shell 200, which can improve the irradiation effectiveness of the emitted light of the light source assembly and provide the user with irradiation light with more uniform and controllable energy distribution.

[0134] In some embodiments, the mating portion is located at an end of the strip portion 121 away from the base portion 110 .

[0135] It can be understood that the closer the mating portion is arranged to the end edge of the flexible circuit substrate 100, the easier it is to obtain a relatively flat and continuous surface of the flexible circuit substrate 100 after installation, thereby reducing the possible warping deformation of the end edge of the flexible circuit substrate 100. Fig.13 The matching part is arranged at one end of each strip-shaped part 121 away from the base part 110. At least one matching part is arranged on each strip-shaped part 121, and it can be arranged as close to the edge of the shell structure as possible when the tension strength is met. Similarly, the connecting part is arranged at the edge of the shell 200, so that the light-emitting part 130 can be arranged in as many areas as possible on the flexible circuit substrate 100 and the light-emitting end 132 of the light-emitting part 130 abuts against the outer wall of the shell 200 under the action of the tension.

[0136] In some embodiments, each strip portion 121 carries at least one light emitting member 130 , and the light emitting member 130 is located between the base portion 110 and the mating portion.

[0137] like Fig.12 As shown, a plurality of light-emitting members 130 are arranged on each strip-shaped portion 121, and a plurality of light-emitting members 130 are arranged on the base portion 110. For each strip-shaped portion 121, the light-emitting member 130 is arranged in the portion between the mating portion and the base portion 110. When the mating portion is mated and connected with the connecting portion, it can ensure that each light-emitting member 130 can abut against the outer wall of the shell 200, thereby improving the installation stability, thereby ensuring that the light-emitting end 132 of the light-emitting member 130 can better fit the outer wall of the shell 200 to form a continuous light-emitting surface, thereby providing users with irradiation light with more uniform and controllable energy distribution.

[0138] In some embodiments, one of the connecting portion and the mating portion is a first positioning hole 125, and the other is a snap-in component 400; the snap-in component 400 can be inserted into the first positioning hole 125 to achieve a mating connection, and the outer wall of the snap-in component 400 at least partially abuts against the inner wall of the first positioning hole 125 and generates relative action force and reaction force, and the action force and reaction force drive the flexible circuit substrate 100 to be tensionedly installed on the outer wall of the shell 200.

[0139] like Fig.13 As shown, the flexible circuit substrate 100 is provided with a plurality of first positioning holes 125, and the housing 200 is provided with a plurality of clips 400, and the plurality of first positioning holes 125 are sleeved and installed in a one-to-one correspondence with the plurality of clips 400. Among them, at least one first positioning hole 125 is provided on the end edge of each strip-shaped portion 121 on the flexible circuit substrate 100 away from the base portion 110, and a plurality of clips 400 are arranged around the outer edge of the housing 200 in a circumferential direction, and the plurality of clips 400 are arranged in a one-to-one correspondence with the plurality of first positioning holes 125. When the flexible circuit substrate 100 is installed on the housing 200, the plurality of first positioning holes 125 are sleeved on the plurality of clips 400, respectively, and the connection is convenient and easy to disassemble and assemble. Preferably, the first positioning hole 125 is an oblong hole, and the long axis of the oblong hole is along the extension direction of the strip-shaped portion 121, so as to facilitate installation.

[0140] like Fig.18As shown, when the first positioning hole 125 (matching portion) on the flexible circuit substrate 100 is sleeved on the clamping member 400 (connecting portion), an interaction force is generated between the first positioning hole 125 and the clamping member 400, and the force acts on the side of the clamping member 400 facing the edge of the housing 200. Under the action of the action force F1 and the reaction force F2, the flexible circuit substrate 100 can be tensioned and installed on the outer wall of the housing 200. On the one hand, the connection firmness and assembly convenience of the flexible circuit substrate 100 can be ensured, so that the flexible circuit substrate 100 can achieve an ideal flatness, which can provide a visual improvement for the user. On the other hand, it also provides tension for the light emitting end 132 of the light emitting member 130 to better fit the outer wall of the housing 200 to form a continuous light emitting surface. The light source assembly forms an optical surface suitable for the outer wall structure of the housing 200, thereby ensuring that the user is provided with irradiation light with a more uniform and controllable energy distribution, and improving the irradiation effectiveness of the emitted light of the light source assembly.

[0141] In some embodiments, when the connecting portion is a clamping member 400 , an annular groove 410 is disposed on the outer wall of the clamping member 400 , and the first positioning hole 125 is sleeved in the annular groove 410 .

[0142] like Fig. 20 and Fig.21 The outer wall of the clamping member 400 is provided with an annular groove 410, and the matching portion (first positioning hole 125) can be sleeved with the clamping member 400 and clamped in the annular groove 410 to achieve fixed installation. Fig.21 A tensioning force is formed in the contact portion between the mating portion (the first positioning hole 125) and the connecting portion (the snap-fit ​​component 400), and the tensioning force can prevent the strip portion 121 from moving along the long axis direction of the snap-fit ​​component 400, and the connection is firm; at the same time, it also provides the light-emitting component 130 with a force component perpendicular to the outer wall of the shell 200, so that the light-emitting end 132 can abut against the outer wall of the shell 200, thereby ensuring that the user is provided with irradiation light with more uniform and controllable energy distribution.

[0143] In some embodiments, the clamping member 400 is provided with a first cone structure 420 and a second cone structure 430 in sequence along its long axis direction, the bottom surface of the first cone structure 420 forms a step surface 421 at the top of the second cone structure 430, and the bottom surface of the second cone structure 430 forms a first groove wall 411 of the annular groove 410, and the second groove wall 412 is located on the annular groove 410 and opposite to the first groove wall 411. The optical device also includes a locking member 300, which has an axial through hole 310 and a bottom wall 331 formed at one end thereof, wherein the bottom wall 331 is located at the end of the abutment portion 330 of the locking member 300, and the axial through hole 310 passes through the bottom wall 331, and a stop portion 320 is formed at the other end of the axial through hole 310 away from the bottom wall 331; when the locking member 300 is sleeved on the clamping member 400 through the axial through hole 310, the stop portion 320 can cross the step surface 421 and clamp therewith, and the gap between the bottom wall 331 and the second groove wall 412 can limit the movement of the strip portion 121 along the long axis direction of the clamping member 400. Specifically, the axial through hole 310 is a stepped hole, and a stopper 320 is formed on the inner wall of the axial through hole 310. The stopper 320 of the axial through hole 310 has the smallest aperture. The step surface 421 protrudes from the outer wall of the clip 400 and the outer diameter of the step surface 421 is larger than the aperture of the stopper 320. The step surface 421 and the annular groove 410 are sequentially arranged in the axial direction of the clip 400. When the axial through hole 310 is sleeved with the clip 400, the stopper 320 crosses the step surface 421 and stops on the step surface 421. In addition, the bottom wall 331 of the locking member 300 abuts against the bottom wall 331 of the locking member 300. On one side of the strip 121, at the same time, the other side of the strip 121 abuts against the second groove wall 412, so that the strip 121 of the flexible circuit substrate 100 can be restricted between the bottom wall 331 and the second groove wall 412 in the width direction while the clamp 400 is connected and fixed with the locking member 300, preventing it from moving along the long axis direction of the clamp 400; in conjunction with this, under the action of the force F1 and the reaction force F2, the flexible circuit substrate 100 is also restricted in the cross-sectional direction of the clamp 400, thereby achieving an ideal positioning and tensioning effect. In the preferred embodiment, the locking member 300 is made of a material with a certain elastic modulus such as rubber or plastic, which is convenient for installation.

[0144] like Fig. 22As shown, in other embodiments, the clamping member 400 is provided with a cone structure along its long axis direction, the bottom surface of the cone structure forms a first groove wall 411 of the annular groove 410, and the second groove wall 412 is located on the annular groove 410 and opposite to the first groove wall 411, and the gap between the first groove wall 411 and the second groove wall 412 can limit the movement of the strip portion 121 along the long axis direction of the clamping member 400. Different from the previous embodiment, this embodiment does not use the locking member 300, but directly uses the annular groove 410 provided on the clamping member 400. Specifically, the strip portion 121 of the flexible circuit substrate 100 has a first positioning hole 125 at its edge, and the first positioning hole 125 can be sleeved in the annular groove 410. After being sleeved, the strip portion 121 is limited between the first groove wall 411 and the second groove wall 412 in the width direction to prevent it from moving along the long axis direction of the clamping member 400. In conjunction with this, under the action of the action force F1 and the reaction force F2, the flexible circuit substrate 100 is also limited in the cross-sectional direction of the clamping member 400, thereby achieving an ideal positioning and tensioning effect. Compared with the previous embodiment, this embodiment can achieve positioning and tensioning effects more quickly.

[0145] like Fig.21 As shown, the axial through hole 310 includes a conical hole section and a circular hole section along its axial direction, and a stop portion 320 is formed between the conical hole section and the circular hole section, wherein the conical hole section is adapted to the outer shape of the second cone structure 430. During installation, the outer wall of the first cone structure 420 facilitates the installation guide of the locking member 300, so that the stop portion 320 passes through the first cone structure 420 and crosses the bottom surface of the first cone structure 420 and then is reversely clamped on the step surface 421 to achieve locking. The conical hole section is sleeved on the second cone structure 430, and the end of the locking member 300 opposite to the conical hole section and away from the circular hole section is the abutment portion 330, and the end of the abutment portion 330 is the bottom wall 331, which can abut the flexible circuit substrate 100, and then the flexible circuit substrate 100 can be limited on the connecting portion or the shell 200 body to prevent the flexible circuit substrate 100 from being deformed and falling out under the action of the tensioning force; and the part between the bottom wall 331 and the stop portion 320 on the locking member 300 can be clamped between the second groove wall 412 and the step surface 421, so as to improve the installation stability and firmness. By providing the first cone structure 420 and the second cone structure 430, a step surface 421 and an annular groove 410 are sequentially formed on the outer wall of the connection portion, so that after the flexible circuit substrate 100 is sleeved in the annular groove 410, the locking member 300 can be sleeved on the end of the connection portion again and be locked at the step surface 421 and abut against the surface of the flexible circuit substrate 100 to prevent it from moving.

[0146] In some embodiments, one of the housing 200 and the flexible circuit substrate 100 is provided with a limiting column 240 , and the other is provided with a limiting hole 1101 , and the limiting hole 1101 can be sleeved on the limiting column 240 .

[0147] like Fig.13 , a limiting hole 1101 is provided on the flexible circuit substrate 100, and a limiting column 240 is provided at a corresponding position on the housing 200. When assembling, the operator firstly matches and installs the limiting hole 1101 with the limiting column 240 to realize the preliminary positioning of the flexible circuit substrate 100, and then limits each strip portion 121 on the clamping member 400 through the first positioning hole 125 correspondingly, and finally sleeves the locking member 300 on the clamping member 400 to complete the assembly. This assembly provides a faster and more accurate assembly form, and combined with the design of the flexible circuit substrate 100, realizes the rapid assembly of the flexible circuit substrate 100 and the housing 200. At the same time, the light emitting end 132 of the light emitting member 130 can be abutted against the outer wall of the housing 200 under the action of the tension force, ensuring that the light emitting ends 132 of all the light emitting members 130 are located on the same arc surface, thereby providing users with more uniform and controllable irradiation light with energy distribution.

[0148] In some embodiments, the base portion 110 of the flexible circuit substrate 100 is provided with a plurality of limiting holes 1101 , and the outer wall of the housing 200 is provided with a plurality of limiting posts 240 , and the plurality of limiting holes 1101 are matched and connected with the plurality of limiting posts 240 in a one-to-one correspondence.

[0149] like Fig.13 The plurality of limiting holes 1101 are arranged at intervals along the central axis of the base portion 110 of the flexible circuit substrate 100, i.e., the Y axis, which is easy to punch on the flexible circuit substrate 100, and is conducive to the plurality of strips 121 symmetrically arranged on both sides of the plurality of limiting holes 1101 having uniform tension after installation, so that the flexible circuit substrate 100 is uniformly stressed. In a preferred embodiment, at least two limiting holes 1101 and two limiting columns 240 are provided, which has the advantage of accurate positioning and can prevent torsional deformation caused by uneven stress when the strip 121 is tensioned and installed.

[0150] In some embodiments, a plurality of light-transmitting regions 210 are provided, a plurality of light-emitting elements 130 are provided, and each light-transmitting region 210 corresponds to at least one light-emitting element 130 .

[0151] like Fig.14As shown, the light-transmitting area 210 on the shell 200 has a surface that is higher than the non-light-transmitting area 220, and the area of ​​a single light-transmitting area 210 is larger than the area of ​​the light-emitting end 132 of a single light-emitting component 130. The light-emitting end 132 of the light-emitting component 130 can abut against the light-transmitting area 210 to provide complete output light. The light-transmitting area 210 can correspond to a plurality of light-emitting components 130, and the light-emitting ends 132 abut against the shell 200. The output light of the light-emitting component 130 can completely pass through the light-transmitting area 210, so that the plurality of light-emitting components 130 have the same consistent output surface, and the output light energy provided is consistent and the light emission is uniform.

[0152] like Fig.15 As shown, when the area of ​​a single light-transmitting region 210 is smaller than the area of ​​the light-emitting end 132 of the light-emitting element 130, the light-emitting end 132 abuts against the non-light-transmitting region 220 on the shell 200, and the light-transmitting region 210 can be a through hole arranged on the non-light-transmitting region 220 or a light-transmitting medium having a thickness less than that of the non-light-transmitting region 220, thereby providing a gap 134 between the light-emitting end 132 and the surface of the light-transmitting region 210, or when the emitted light passes through the light-transmitting region 210, there will be partial obstruction, thereby providing an optimized design with adjustable light throughput, further meeting the functional requirements of the device.

[0153] like Fig.17 As shown, the housing 200 is made of a transparent material. When the housing 200 is made of a transparent material, the entire area of ​​the housing 200 is a light-transmitting area 210, and the light-emitting end 132 of the light-emitting element 130 can directly abut against the outer wall of the housing 200, so that the multiple light-emitting elements 130 have a uniform and consistent light-emitting intensity and a direction of the light-emitting light determined based on the curved surface of the housing 200, which is conducive to the control of light irradiation energy and the assembly and production of the product; when the housing 200 adopts a fully transparent design, most of the flexible circuit substrate 100 facing the user side and the light-emitting elements 130 arranged thereon can be fully exposed within the visible range, and the cutting form of the flexible circuit substrate 100 ensures that the curved substrate exposed within the user's visible range is visually complete, continuous and unified, that is, there is no obvious crease or local bulge, which effectively improves the user experience; more importantly, the fully transparent housing 200 design can ensure the effectiveness of light irradiation of the light-emitting element 130 and maximize the light irradiation range.

[0154] In some embodiments, the optical assembly further includes an attachment 133 , which is sleeved on the light emitting end 132 of the light emitting element 130 , and an end 1331 of the attachment 133 protrudes from the light emitting end 132 of the light emitting element 130 and abuts against an outer wall of the housing 200 .

[0155] like Fig.16As shown, an accessory 133 is sleeved on the outer side of the light-emitting component 130. The accessory 133 can be a cylindrical opaque material. The end 1331 of the accessory 133 abuts against the shell 200, so that a gap 134 is provided between the light-emitting end 132 of the light-emitting component 130 and the surface of the shell 200, thereby being able to adjust the irradiation area of ​​the emitted light on the skin 500 and having the irradiation effect of protecting the light-emitting component 130.

[0156] In some embodiments, the shell 200 is a hemispherical shell or a hemispherical shell structure, and accordingly, the flexible circuit substrate 100 is installed on the shell 200, and a plurality of strip portions 121 are tensionedly installed on the shell 200 so that the light-emitting element 130 abuts against the outer wall of the shell 200, forming an optical surface suitable for the outer wall structure of the shell 200, which is suitable for a hair growth cap or a facial irradiation device, and meets the irradiation requirements of the curved surface area.

[0157] Embodiment 7: Optical components

[0159] It can be understood that the clip 400 is a component arranged independently of the flexible circuit substrate 100 and the shell 200, and its arrangement number corresponds to the first positioning hole 125 and the second positioning hole 230. The first positioning hole 125 can be an oblong hole opened on the strip portion 121, and the second positioning hole 230 can be a hole type adapted to the outer wall contour of the clip 400 to ensure that the clip 400 has a controllable relative gap or no gap after being connected to the second positioning hole 230, thereby achieving the flexible circuit substrate 100 can be tensionedly mounted on the shell 200. During assembly, the clamping member 400 may be first inserted into the second positioning hole 230 and the connection relationship between the two may be maintained, and then the flexible circuit substrate 100 may be inserted into the clamping member 400 through the first positioning hole 125. Since the housing 200 and the clamping member 400 already have a relative connection position relationship, after the flexible circuit substrate 100 is inserted and connected, the inner wall of the first positioning hole 125 may generate a relative action force and reaction force with the outer wall of the clamping member 400, and the action force and reaction force drive the flexible circuit substrate 100 to be installed on the outer wall of the housing 200 in a tensioned manner. This embodiment does not limit the insertion order of the clamping member 400, the first positioning hole 125, and the second positioning hole 230, and it is sufficient that the clamping member 400 can be inserted into the first positioning hole 125 and the second positioning hole 230 and their relative position relationship is maintained.

[0160] In some embodiments, the clamping member 400 may be transitionally fitted with the first positioning hole 125 or may be transitionally fitted with the second positioning hole 230 , and the transitionally fitted may include an interference fit and a clearance fit. Specifically, an annular groove 410 is provided on the outer wall of the clamp 400, the first positioning hole 125 is an oblong hole, and the minor axis length thereof is greater than or equal to the outer diameter of the annular groove 410, and the second positioning hole 230 is a circular hole, and the diameter thereof is less than or equal to the outer diameter of the annular groove 410. The clamp 400 is a structural member with a certain elastic modulus, and may be made of rubber or a deformable structure to ensure that the first positioning hole 125 and the second positioning hole 230 can be inserted therein. When the first positioning hole 125 and the second positioning hole 230 are sleeved in the annular groove 410, the annular groove 410 and the second positioning hole 230 are interference fit, and are clearance fit with the first positioning hole 125. The inner wall of the first positioning hole 125 and the outer wall of the clamp 400 generate relative action and reaction forces, and the action and reaction forces drive the flexible circuit substrate 100 to be tensionedly installed on the outer wall of the shell 200.

[0161] See also Fig.23In some embodiments, a cone structure is provided at one end of the clamping member 400 along its long axis direction, and the other end is an end 440. An annular groove 410 is formed between the cone structure and the end 440. The bottom surface of the cone structure forms a first groove wall 411 of the annular groove 410. A second groove wall 412 is located on the annular groove 410 and opposite to the first groove wall 411. At the same time, gaps 450 with same-side openings are respectively formed on both axial sides of the clamping member 400. The gaps 450 can ensure that the first positioning hole 125 and / or the second positioning hole 230 partially compress the cone structure inward during the process of connecting to the annular groove 410 to ensure smooth clamping to the annular groove 410. After clamping, the inner wall of the first positioning hole 125 and the outer wall of the clamping member 400 generate relative action and reaction forces, and the action and reaction forces drive the flexible circuit substrate 100 to be tensionedly installed on the outer wall of the housing 200. At the same time, the annular groove 410 has a groove width that can limit the relative movement of the belt portion 121 and the housing 200 along the long axis direction of the clamping member 400 .

[0162] See also Fig.24 In other embodiments, a cone structure is provided at one end of the clamping member 400 along its long axis direction, and the other end is an end 440. An annular groove 410 is formed between the cone structure and the end 440. The bottom surface of the cone structure forms a first groove wall 411 of the annular groove 410. A second groove wall 412 is located on the annular groove 410 and opposite to the first groove wall 411. At the same time, an oblong gap 450 is formed in the axial middle section of the clamping member 400. The gap 450 can ensure that the first positioning hole 125 and / or the second positioning hole 230 can partially compress the cone structure inward during the process of connecting to the annular groove 410 to ensure smooth clamping to the annular groove 410. After clamping, the inner wall of the first positioning hole 125 and the outer wall of the clamping member 400 generate relative action and reaction forces, and the action and reaction forces drive the flexible circuit substrate 100 to be tensionedly installed on the outer wall of the housing 200. At the same time, the annular groove 410 has a groove width that can limit the relative movement of the belt portion 121 and the housing 200 along the long axis direction of the clamping member 400 .

The flexible circuit substrate 100 achieves an ideal flatness, which can not only provide a visual improvement for the user, but also the more ideal optical surface further improves the irradiation effectiveness of the emitted light; on the other hand, it also provides a structural improvement that is easier to assemble.
