[0067] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0068] In the description of the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0069] Figure 1 This is an application scenario diagram of a visualization panel in related technologies.

[0070] In the related art, the visualization panel 200 is provided with a housing 300, a plurality of light-emitting elements 500 and a plurality of light-guiding structures 600. The housing 300 is provided with a plurality of light-transmitting portions 301 corresponding to the light-emitting elements 500, and the light-transmitting portions 301 may be a hole structure or a light-transmitting material structure, etc. The light-guiding structure 600 is provided between the light-transmitting portion 301 of the housing 300 and the corresponding light-emitting element 500. When the light-emitting element 500 emits light, the light-guiding structure 600 receives the light of the light-emitting element 500 and guides the light to the light-transmitting portion 301, so that the user can observe the light-emitting state of the light-transmitting portion 301 from the outside of the housing 300.

[0071] However, since the light guide structure 600 is made of transparent plastic material and has the characteristic of being transparent throughout, when the light guide structure 600 receives light from the light-emitting element 500 and transmits it, part of the light may leak from the side of the light guide structure 600, causing cross-lighting between multiple adjacent light guide structures 600.

[0072] For example, between two adjacent light-emitting elements 500, when one of the light-emitting elements 500 emits light, one of the light-guiding structures 600 transmits the light to one of the light-transmitting portions 301, causing one of the light-transmitting portions 301 to light up. At the same time, part of the light from one of the light-guiding structures 600 may be transmitted from the side to the other light-guiding structures 600, indicating that the other light-transmitting portion 301 is faintly lit, affecting the light-emitting stability.

[0073] To this end, the present application provides a light guide component and a visualization panel, which have the effect of improving the light emission stability.

[0074] Figure 2 It is a schematic diagram of the structure of the visualization panel of an embodiment of the present application. Figure 3 It is a structural schematic diagram from a front view of the light guide assembly of the first embodiment of the present application.

[0075] like Figure 2 and Figure 3 As shown, the present application first provides a light guide assembly 100, which is applied to a visualization panel 200. The visualization panel 200 may include a housing 300, a substrate 400, a light emitting element 500 and a light guide assembly 100, wherein the number of the light emitting elements 500 is greater than or equal to 2, the housing 300 is provided with a plurality of light-transmitting portions 301 corresponding to the light emitting elements 500, the light emitting elements 500 and the light guide assembly 100 are both provided on the substrate 400, and the substrate 400 is fixed to the housing 300. The light guide assembly 100 is provided between the plurality of light emitting elements 500 and the corresponding light-transmitting portions 301, and the light guide assembly 100 is used to receive light from the light emitting elements 500 and guide the light to the corresponding light-transmitting portions 301, so that the user can observe the light-emitting state of the light-transmitting portions 301.

[0076] The visualization panel 200 provided in the present application can be applied to electronic devices, and the light-emitting state of each light-transmitting portion 301 of the visualization panel 200 can be used to indicate the working state of the electronic device.

[0077] In the example of the present application, the electronic device can be applied to the photovoltaic system, and the electronic device can be a photovoltaic inverter device. The photovoltaic inverter device can feedback different working states through each light-transmitting portion 301 of the visualization panel 200. For example, each light-transmitting portion 301 may include a first light-transmitting hole, a second light-transmitting hole, and a third light-transmitting hole that are spaced apart, wherein the first light-transmitting hole is used to feedback the power-on / power-off state of the photovoltaic inverter device, the second light-transmitting hole is used to feedback the connection state between the photovoltaic inverter device and other devices, and the third light-transmitting hole is used to feedback whether the photovoltaic inverter device is faulty. It can be understood that the specific structure of the visualization panel 200 can also be set according to the actual application scenario, for example, the number and distribution of the light-transmitting portions 301, other configurations of the visualization panel 200 (such as touch buttons, display modules, etc.) are set, and the installation position of the visualization panel 200 is set, etc., and this application does not limit this.

[0078] Figure 4 It is a structural schematic diagram of the light guide assembly from a back view of the first embodiment of the present application.

[0079] like Figure 2 , Figure 3 and Figure 4 As shown, the light guide assembly 100 includes a fixing plate 10, a light guide column 20 and a light shielding member 30. The number of the light guide columns 20 is greater than or equal to 2, and the plurality of light guide columns 20 are arranged at intervals on the fixing plate 10. The first end 21 of the light guide column 20 is used to dock with the light emitting element 500, and the second end 22 of the light guide column 20 points to the light-transmitting portion 301 corresponding to the light emitting element 500. The light shielding member 30 is arranged on the side of the light guide column 20, and the light shielding member 30 is used to shield the propagation of light.

[0080] Exemplarily, the fixing plate 10 is fixedly connected to the base plate 400, the light guide column 20 is fixed to the fixing plate 10, and the positions of the plurality of light guide columns 20 correspond to the positions of the plurality of light emitting elements 500. In the example of the present application, the number of the light guide columns 20 is 2; in other examples, the number of the light guide columns 20 may also be greater than 2, and may be specifically configured according to the number of the light emitting elements 500.

[0081] The light guide column 20 is made of a transparent plastic material, and the two ends of the light guide column 20 respectively form a first end 21 and a second end 22. The first end 21 of the light guide column 20 is close to the corresponding light emitting element 500 to dock with the light emitting element 500, and the second end 22 of the light guide column 20 is close to the light-transmitting portion 301 on the housing 300 corresponding to the light emitting element 500. The light emitted by each light emitting element 500 can directly enter the corresponding light guide column 20, and propagate to the corresponding light-transmitting portion 301 under the light guiding effect of the corresponding light guide column 20.

[0082] The shading member 30 is made of an opaque material and is located on the side of the light guide column 20 to prevent light from propagating from the side of the light guide column 20 to the light guide column 20. In this way, only the corresponding light-emitting element 500 is allowed to propagate light from the first end 21 of the light guide column 20 to the light guide column 20, preventing other light-emitting bodies (such as other light-emitting elements 500 or other adjacent light guide columns 20) from affecting the light of the light guide column 20.

[0083] It can be understood that in the process that the light emitted by the light-emitting element 500 passes through the corresponding light guide column 20 and propagates to the corresponding light-transmitting portion 301, the light shielding effect of the shading member 30 is used to prevent the light inside the light guide column 20 from propagating from the side to the outside of the light guide column 20, and at the same time prevent the light outside the light guide column 20 from propagating from the side to the light guide column 20, thereby effectively reducing the light crosstalk phenomenon between multiple adjacent light guide columns 20 and improving the light emission stability.

[0084] It is worth noting that the structures of the multiple light guide columns 20 in the embodiment of the present application can be completely consistent, or there can be partial structural inconsistency (for example, different inner surface shapes), as long as each light guide column 20 can cooperate with the shading member 30.

[0085] Figure 5 It is a schematic exploded view of the light guide assembly of the first embodiment of the present application.

[0086] like Figure 2 and Figure 5As shown, in one embodiment, the fixing plate 10 is made of a transparent plastic material, and the fixing plate 10 and the plurality of light guide columns 20 are integrally formed, so that the plurality of light guide columns 20 are fixedly connected to the fixing plate 10, and the first end 21 of the light guide column 20 extends in a direction close to the light-emitting element 500 on one side of the fixing plate 10, and the second end 22 of the light guide column 20 is formed to protrude toward the light-transmitting portion 301 on the other side of the fixing plate 10. The fixing plate 10 and the light guide column 20 are integrally connected, and there is no need to fix the light guide column 20 to the fixing plate 10 through other mounting structures, thereby simplifying the processing technology and reducing material costs. In other embodiments, the fixing plate 10 and the light guide column 20 can also be connected separately, such as the light guide column 20 is plugged into the fixing plate 10 and fixed to the fixing plate 10 by bonding.

[0087] Furthermore, the fixing plate 10 is provided with a groove portion 11, which is provided between a plurality of adjacent light guide columns 20, and is used to block the propagation of light. Exemplarily, the groove portion 11 is formed by the surface of the fixing plate 10 being recessed inwardly, and the groove portion 11 forms a stepped fault structure inside the fixing plate 10, blocking the transmission of light between the positions of the fixing plate 10 close to both sides of the groove portion 11; in other embodiments, the groove portion 11 may also be a through groove structure, that is, passing through both sides of the fixing plate 10, to achieve the effect of light blocking.

[0088] It can be understood that since the fixing plate 10 has a certain light transmittance, when the light-emitting element 500 emits light to the corresponding light guide column 20, part of the light may be transmitted to the adjacent light guide column 20 through the part of the fixing plate 10 close to the light-emitting element 500, and the groove portion 11 has a blocking effect on this part of the light, further reducing the cross-light phenomenon between multiple adjacent light guide columns 20.

[0089] In one embodiment, the light guide column 20 is extended along the light propagation direction of the light emitting element 500, that is, the length direction of the light guide column 20 is parallel to the light propagation direction of the light emitting element 500. The light guide column 20 is connected to one end of the fixing plate 10 to form a second end 22, and the light guide column 20 is away from the fixing plate 10 to form a first end 21.

[0090] In one embodiment, the inner surface of the light guide column 20 is preferably a concave light-scattering structure to enhance the light transmission effect.

[0091] In one embodiment, the shading member 30 is located on the side of the corresponding light guide column 20 facing other adjacent light guide columns 20. In this way, the shading member 30 can effectively prevent light from propagating between the sides of multiple adjacent light guide columns 20.

[0092] Figure 6 for Figure 3 A partial schematic diagram of the cross section along line AA.

[0093] like Figure 2 and Figure 6 As shown, in one embodiment, the shading member 30 is in the shape of a sleeve as a whole. The shading member 30 is provided with a receiving groove 31, which runs through both ends of the shading member 30, and the light guide column 20 is received in the receiving groove 31. In this way, the shading member 30 is sleeved on the light guide column 20 to achieve a comprehensive shading effect, and both ends of the light guide column 20 are respectively exposed at both ends of the shading member 30, so that the two ends of the light guide column 20 are respectively connected with the light-emitting element 500 and the light-transmitting portion 301. In addition, the overall length of the shading member 30 is greater than the length of the light guide column 20 exposed from the fixing plate 10, so that a certain space is reserved between the end of the shading member 30 away from the fixing plate 10 and the first end 21 of the light guide column 20 for accommodating the light-emitting element 500.

[0094] In one embodiment, the shading member 30 and the light guide column 20 are detachably connected, so that it is convenient for users to disassemble, assemble and replace the shading member 30 and the light guide column 20 .

[0095] Specifically, a snap-fit ​​structure is provided between the light shielding member 30 and the light guide column 20 , and the light shielding member 30 and the light guide column 20 are detachably connected via the snap-fit ​​structure, so as to improve the efficiency of assembly and disassembly of the light shielding member 30 and the light guide column 20 .

[0096] Exemplarily, the snap-fit ​​structure includes a snap-fit ​​block 32 and a clamping portion 25, the snap-fit ​​block 32 is arranged on the groove wall of the receiving groove 31, and the clamping portion 25 is arranged on the side of the light guide column 20, and the snap-fit ​​block 32 and the clamping portion 25 are engaged and clamped in the length direction of the light guide column 20, so that the shading member 30 and the light guide column 20 are relatively fixed.

[0097] When the shading member 30 needs to be installed on the light guide column 20, the shading member 30 can be sleeved on the first end 21 of the light guide column 20, and the shading member 30 can be pushed toward the second end 22 of the light guide column 20, so that the clamping block 32 and the clamping portion 25 are clamped together through interference fit. When the shading member 30 needs to be removed from the light guide column 20, the shading member 30 can be pulled toward the first end 21 of the light guide column 20, so that the clamping block 32 and the clamping portion 25 are separated through interference fit.

[0098] In one embodiment, the clamping block 32 is formed by a protruding arrangement of the groove wall of the receiving groove 31, the clamping portion 25 is a clamping groove formed by a depression on the side of the light guide column 20, and the clamping block 32 is adapted to the clamping portion 25. The clamping block 32 is received in the clamping portion 25 and abuts against the groove wall of the clamping portion 25 along the length direction of the light guide column 20 to achieve a clamping fit.

[0099] In one embodiment, the number of the clamping portions 25 is greater than or equal to 2, and the plurality of clamping portions 25 are distributed at intervals around the circumference of the light guide column 20. The number and distribution of the clamping blocks 32 correspond to the clamping portions 25. Exemplarily, the number of the clamping portions 25 is 2, and the two clamping portions 25 are relatively arranged on the sides of the light guide column 20. The number of the clamping blocks 32 is 2, and the positions of the two clamping blocks 32 correspond to the arrangement of the two clamping portions 25. In this way, the plurality of clamping blocks 32 can be respectively engaged with the plurality of clamping portions 25 to improve the connection stability between the shading member 30 and the light guide column 20.

[0100] Figure 7 It is a schematic exploded view of the light guide column and the light shielding element of the first embodiment of the present application.

[0101] like Figure 6 and Figure 7 As shown, in one embodiment, the shade member 30 is provided with a clearance opening 33, which is provided on the side of the clamping block 32, and the clearance opening 33 is connected to the shade member 30. Exemplarily, the clearance opening 33 is provided on both sides of each clamping block 32, and the clearance opening 33 penetrates the inner side and the outer side of the shade member 30, and the clearance opening 33 penetrates one end of the shade member 30 along the side of the clamping block 32. By setting the clearance opening 33, the deformation range of the portion of the shade member 30 close to the clamping block 32 can be increased, so that the deformation of the clamping block 32 and the holding portion 25 can be more labor-saving when the interference fit occurs, which is convenient for users to install or remove the shade member 30.

[0102] Figure 8 FIG. 1 is a schematic diagram of the distribution of a plurality of light guide rods according to the first embodiment of the present application.

[0103] like Figure 7 and Figure 8 As shown, further, the side surface of the light guide column 20 has a first surface 23 and a second surface 24. Among them, the first surface 23 of the light guide column 20 faces other adjacent light guide columns 20, and the clamping portion 25 is arranged on the second surface 24, so that the clearance opening 33 is distributed and arranged corresponding to the second surface 24. Exemplarily, the cross section of the light guide column 20 is rectangular (the cross section direction is perpendicular to the length direction of the light guide column 20), and four side surfaces are formed on the circumference of the light guide column 20, then the side surface facing other light guide columns 20 among the four side surfaces forms the first surface 23, and the remaining other side surfaces among the four side surfaces form the first surface 24; this embodiment takes two oppositely arranged light guide columns 20 as an example, that is, the side surface of the two light guide columns 20 facing each other is the first surface 23, it can be understood that if the number or distribution of the light guide columns 20 changes, the distribution of the first surface 23 and the second surface 24 can also be adaptively changed.

[0104] On the other hand, the circumferential side of the light guide column 20 in the present embodiment is bent to form four side faces. In other embodiments, the circumferential side of the light guide column 20 may also be continuously distributed (for example, the cross-section of the light guide column 20 is waist-shaped, and the cross-sectional direction is perpendicular to the length direction of the light guide column 20) so that the circumferential side of the light guide column 20 forms four regions, and the side faces facing other light guide columns 20 in the four regions form a first face 23, and the remaining other side faces in the four regions form a second face 24.

[0105] It can be understood that, when the light guide column 20 is not provided with the light shielding member 30, light crosstalk is likely to occur between the first surface 23 of the light guide column 20 and other adjacent light guide columns 20, while light crosstalk is unlikely to occur between the second surface 24 of the light guide column 20 and other adjacent light guide columns 20. In this embodiment, the light shielding member 30 completely shields the first surface 23 by distributing the clearance openings 33 on the second surface 24, thereby preventing light from interfering with the light guide column 20 through the clearance openings 33.

[0106] In one embodiment, the inner shape of the light shielding member 30 is arranged to correspond to the peripheral shape of the light guide column 20 , so that the light shielding member 30 and the light guide column 20 are positioned and matched in the circumferential direction of the light guide column 20 .

[0107] Exemplarily, the cross section of the light guide column 20 is rectangular (the cross section direction is perpendicular to the length direction of the light guide column 20), and the peripheral side of the light guide column 20 is formed with four side surfaces, and an angle is formed between two adjacent side surfaces; the shape of the light shielding member 30 is adapted to the shape of the light guide column 20, so that the inner side of the light shielding member 30 is also formed with four side surfaces, and an angle is formed between two adjacent side surfaces. When the light shielding member 30 is sleeved on the light guide column 20, the inner side of the light shielding member 30 is parallel to the peripheral side of the light guide column 20. In other embodiments, the cross section of the light guide column 20 can also be other shapes (for example, a waist shape, with the cross section direction perpendicular to the length direction of the light guide column 20), and the shape of the light shielding member 30 is adaptively modified corresponding to the light guide column 20, as long as the effect of matching and positioning between the light guide column 20 and the light shielding member 30 can be achieved.

[0108] The circumferential side of the light guide column 20 cooperates with the inner side of the shading member 30 to limit the displacement of the shading member 30 and the light guide column 20 in the circumferential direction. On the one hand, the clamping block 32 can be aligned with the clamping portion 25 to prevent the shading member 30 from being misassembled or failing to cooperate. On the other hand, the clearance opening 33 can be prevented from moving to the first surface 23 to cause light leakage from the first surface 23.

[0109] In one embodiment, the opening area of ​​the receiving groove 31 close to one end of the fixing plate 10 is larger than the cross-sectional area of ​​the first end 21 of the light guide column 20 (the cross-sectional direction is perpendicular to the length direction of the light guide column 20). Exemplarily, the light guide column 20 gradually shrinks in a direction away from the fixing plate 10, and the shape of the light shielding member 30 is adapted to the shape of the light guide column 20. In this way, when the user sets the light shielding member 30 on the first end 21 of the light guide column 20, the first end 21 of the light guide column 20 can easily enter the receiving groove 31, which is convenient for the user to install the light shielding member 30.

Fig.10 It is a cross-sectional schematic diagram of a light guide column and a light shielding element according to the second embodiment of the present application.

[0111] like Fig. 9 and Fig.10 As shown, the difference between this embodiment and the first embodiment includes: the light guide column 20 is evenly distributed along its length, and the clamping portion 25 is a convex structure formed by protruding from the surface of the light guide column 20. The clamping block 32 of the shading member 30 is inclined toward the inner side of the shading member 30.

[0112] When the shading piece 30 is sleeved on the light guide column 20, the clamping portion 25 is pressed against the clamping portion 25 along the length direction of the light guide column 20 to form a clamping fit. At the same time, a gap is left between the inner side of the shading piece 30 and the peripheral side of the light guide column 20 to facilitate the removal of the shading piece 30 from the light guide column 20.

[0113] Fig.11 It is a structural schematic diagram of the light guide assembly of the third embodiment of the present application from a front perspective. Fig.12 It is a cross-sectional schematic diagram of a light guide column and a light shielding element according to the third embodiment of the present application.

[0114] like Figure 2 , Fig.11 and Fig.12 As shown, the difference between this embodiment and the first embodiment includes: the shading member 30 includes a shading portion 40 and a bottom plate portion 50, the shading portion 40 is sleeved on the light guide column 20, and a receiving groove 31 is formed on the inner side of the shading portion 40. The bottom plate portion 50 is fixed to the shading portion 40. Exemplarily, the bottom plate portion 50 and the shading portion 40 are integrally formed, the bottom plate portion 50 is located at one end of the shading portion 40 close to the fixed plate 10, the bottom plate portion 50 is distributed along the outer side of the shading portion 40, and the bottom plate portion 50 is parallel to the fixed plate 10; in other embodiments, the bottom plate portion 50 and the shading portion 40 can also be connected separately, for example, the bottom plate portion 50 and the shading portion 40 are fixed by bonding.

[0115] The fixing plate 10 is provided with a mounting member 60 for mounting the bottom plate 50 . Thus, the fixing plate 10 is fixed to the bottom plate 50 via the mounting member 60 , so that the shading member 40 is fixed to the peripheral side of the light guide column 20 , and the shading member 30 is fixed to the light guide column 20 .

[0116] It is worth noting that, unlike the first embodiment, the light shading member 30 in this embodiment itself does not need to be snap-fitted with the light guide column 20, so there is no need to process the corresponding snap-fitting structure on the light guide column 20 to ensure the structural integrity of the light guide column 20. By not needing to process the yield structure on the peripheral side of the light shading member 30, the risk of cross-lighting in the light guide column 20 is further reduced.

[0117] Fig.13 It is a schematic exploded view of a shading member and a fixing plate according to a third embodiment of the present application. Fig.14 Schematic diagram of the matching relationship between the mounting member and the bottom plate portion of the third embodiment of the present application.

[0118] like Fig.13 and Fig.14 As shown, in one embodiment, the mounting method of the mounting member 60 on the bottom plate portion 50 is a non-detachable mounting. Exemplarily, the bottom plate portion 50 is provided with a positioning hole 51, and the positioning hole 51 penetrates both sides of the bottom plate portion 50 along the thickness direction of the bottom plate portion 50. The mounting member 60 is located on the side of the fixed plate 10 where the light guide column 20 is provided, and the mounting member 60 extends along the length direction of the light guide column 20. The mounting member 60 is plugged into the positioning hole 51, one end of the mounting member 60 is fixed to the fixed plate 10, and the other end of the mounting member 60 is exposed in the positioning hole 51 and is provided with a plug 61, and the plug 61 is fixed to the bottom plate portion 50. Exemplarily, the cross-sectional area of ​​the plug 61 is larger than the cross-sectional area of ​​the positioning hole 51 (the cross-sectional direction is perpendicular to the length direction of the mounting member 60), so that the plug 61 limits the bottom plate portion 50 along the length direction of the mounting member 60, and prevents the bottom plate portion 50 from detaching from the fixed plate 10.

[0119] Specifically, a plurality of mounting members 60 are provided, and the plurality of mounting members 60 are spaced apart from each other, and the number and distribution of the positioning holes 51 are arranged corresponding to the mounting members 60. The plurality of mounting members 60 are respectively matched with the plurality of positioning holes 51 through the plurality of plugs 61, so as to improve the installation stability of the bottom plate 50. At the same time, the plurality of mounting members 60 are inserted into the corresponding positioning holes 51, so as to limit the bottom plate 50 and prevent the bottom plate 50 from displacement and deviation.

[0120] In one embodiment, the mounting member 60 is made of hot-melt material, so that the plug 61 can be formed by hot-melting the end of the mounting member 60. Exemplarily, the mounting member 60 is made of plastic material, and the mounting member 60 and the fixing plate 10 are integrally formed; in other embodiments, the mounting member 60 and the fixing plate 10 can also be connected separately, for example, by fixing the mounting member 60 and the fixing plate 10 by bonding.

[0121] When fixing the shading member 30, the bottom plate portion 50 can be placed on the surface of the fixing plate 10 so that the mounting member 60 is inserted into the positioning hole 51, and then the end of the mounting member 60 exposed to the positioning hole 51 is heated by a heating tool (such as a welder) so that the end of the mounting member 60 is hot-melted to form a plug 61, thereby completing the fixation of the bottom plate portion 50 and improving the installation speed of the bottom plate portion 50.

[0122] Furthermore, the inner side of the positioning hole 51 gradually expands in the direction away from the fixing plate 10. For example, the inner diameter of the end of the positioning hole 51 away from the fixing plate 10 is larger than the inner diameter of the other end of the positioning hole 51. In this way, the space filled by the end of the mounting member 60 during hot melting can be enlarged, which is convenient for users to heat the mounting member 60, and at the same time, the overall volume of the plug 61 is increased, and the connection stability between the plug 61 and the bottom plate 50 is improved.

[0123] In one embodiment, a plurality of adjacent bottom plate portions 50 are fixedly connected. This embodiment takes two light guide columns 20 disposed opposite to each other as an example, that is, the two bottom plate portions 50 are integrally connected, and a plurality of positioning holes 51 are distributed around the overall bottom plate structure formed by the two bottom plate portions 50; it can be understood that the number and distribution of the positioning holes 51 can also be adaptively adjusted.

[0124] It can be understood that the adjacent multiple shading portions 40 form an integral shading structure that can be simultaneously mounted on multiple light guide columns 20. During installation, the shading structures of multiple light guide columns 20 can be installed simultaneously, thereby improving installation efficiency.

[0125] Fig.15 This is a schematic diagram of the matching relationship between the mounting member and the bottom plate portion of the fourth embodiment of the present application.

[0126] like Fig.15 As shown, the difference between this embodiment and the fourth embodiment includes: the plug 61 can be formed by dispensing glue on the end of the mounting member 60.

[0127] When fixing the shading member 30, the bottom plate portion 50 can be placed on the surface of the fixing plate 10 so that the mounting member 60 is inserted into the positioning hole 51, and then glue is dispensed on the end of the mounting member 60 exposed in the positioning hole 51 using a glue dispensing tool. The solidified glue forms a plug 61 and bonds the mounting member 60 and the bottom plate portion 50, thereby completing the fixation of the bottom plate portion 50 and improving the installation stability of the bottom plate portion 50.

[0128] Fig.16 This is a schematic diagram of the matching relationship between the mounting member and the bottom plate portion of the fifth embodiment of the present application.

[0129] like Fig.16As shown, the difference between this embodiment and the third embodiment includes: the mounting member 60 is mounted on the bottom plate 50 in a detachable manner. In this way, it is convenient for the user to disassemble and replace the light shielding member 30 and the light guide column 20. Exemplarily, the mounting member 60 can be a mounting screw 62, and the fixing plate 10 is provided with a screw hole adapted to the mounting screw 62.

[0130] When fixing the shading member 30, the bottom plate portion 50 can be placed on the surface of the fixing plate 10 so that the positioning hole 51 of the bottom plate portion 50 is connected to the screw hole of the fixing plate 10, and then the mounting screws 62 are passed through the positioning hole 51 and threadedly connected to the screw hole to complete the fixation of the bottom plate portion 50.

The light-emitting element 500 and the light-guiding assembly 100 are both arranged on the substrate 400, and the substrate 400 is fixed to the housing 300.

[0133] Exemplarily, the housing 300 may be a shell structure of an electronic device. A through hole structure is provided on the surface of the housing 300 to form a light-transmitting portion 301. The substrate 400 is arranged opposite to the fixing plate 10, the substrate 400 and the fixing plate 10 are parallel to each other and have a spacing therebetween, and the substrate 400 and the fixing plate 10 are bolted and fixed by connecting columns.
