[0022] 4 to 6, the lampshade provided by the present invention will be described. The lampshade includes an outer tube 10 and a heat dissipation member 20. Fixing sheets 14 are protruding from the inner wall of the outer tube 10 on both sides facing each other. The heat dissipation member 20 is mounted inside the outer tube 10. The heat dissipation member 20 is provided with mounting grooves 21, which are used to mount a light source plate 30. However, the two fixing sheets 14 are attached to the heat dissipation member 20 and are used to reflect the light beams of the light source plate 30.

[0023] Compared with the prior art, the lampshade provided in this embodiment has the following features: when the light source plate 30 is attached in the mounting groove 21 of the heat dissipation member 20, the light emitted from the light source plate 30 passes through the outer tube 10 to illuminate the outside, and some of the light is reflected by the inner wall of the outer tube 10 to the fixing sheet 14, and the fixing sheet 14 is made of a reflective material, so that the light is reflected again and the light is emitted to the positions of the outer tube 10 corresponding to the two fixing sheets 14. The fixing sheet 14 is attached to the heat dissipation member 20, which not only improves the stability of the heat dissipation member 20, but also reflects the light when the light source plate 20 emits light, expands the light output range of the light source plate 30 in the circumferential direction of the outer tube 10, improves the optical reflection effect, and improves the optical effect of the entire lamp; and since the fixing sheet 14 is attached to the heat dissipation member 20, the stability of the heat dissipation member 20 after installation can also be improved.

[0024] For a specific light reflection diagram, please refer to Figure 4. In Figure 4, the dashed lines with arrows indicate light rays.

[0025] In some embodiments, one specific embodiment of the fitting of the outer tube 10 and the heat dissipation member 20 can adopt the structure shown in Figures 4 to 5. Referring to Figures 4 to 5, a first sliding groove 11 extending along the axial direction of the outer tube 10 is provided on the inner wall of the outer tube 10, and the heat dissipation member 20 is slidably fitted into the first sliding groove 11. The heat dissipation member 20 is slidably installed in the outer tube 10, which is easy to operate, shortens the assembly time, and improves production efficiency.

[0026] In some embodiments, one improved embodiment of the outer tube 10 can adopt the structure shown in Figures 4 to 5. Referring to Figures 4 to 5, a number of ridges 13 are protruded on the inner wall of the outer tube 10, and the space between two adjacent ridges 13 forms a first sliding groove 11. The first sliding groove 11 is formed by providing the ridges 13, and compared with directly drilling a groove on the inner wall of the outer tube 10, this embodiment can select an outer tube 10 with a thin thickness, which not only improves the brightness of the illumination, but also reduces the amount of molding material used for the outer tube 10, thereby further saving costs.

[0027] Two or more convex strips 13 may be installed, and the multiple convex strips 13 are distributed at intervals along the vertical direction. When the number of convex strips 13 is greater than two, multiple first sliding grooves 11 distributed along the vertical direction are formed. In this way, when installing the heat dissipation member 20, an appropriate first sliding groove 11 can be selected and installed, and the distance between the light source plate 30 installed on the heat dissipation member 20 and the side wall of the outer tube 10 can be changed to adjust the light irradiation intensity and meet the different light irradiation needs of users.

[0028] In some embodiments, one improved embodiment of the heat dissipation member 20 may adopt the structure shown in Figures 4 and 6. Referring to Figures 4 and 6, the heat dissipation member 20 has a first sliding bar 22 fitted into the first sliding groove 11, and further has a second sliding bar 23 located below the first sliding bar 22 at a distance, the first sliding bar 22 and the second sliding bar 23 are surrounded to form a second sliding groove, one of which is a protruding strip 13 slidably fitted into the second sliding groove. The first sliding bar 22 is fitted into the first sliding groove 11, and one of which is a protruding strip 13 is fitted into the second sliding groove, so that the position of the heat dissipation member 20 can be restricted in the vertical direction, and the light output effect of the light source plate 30 is prevented from being affected by the sliding of the heat dissipation member 20.

[0029] In some embodiments, one specific embodiment of the heat dissipation member 20 may adopt the structure shown in FIG. 4 and FIG. 6. Referring to FIG. 4 and FIG. 6, two convex plates 24 are installed at an interval on the heat dissipation member 20, and the space between the two convex plates 24 forms the mounting groove 21, the plate surface of the convex plate 24 is parallel to the axial direction of the outer tube 10, and the two convex plates 24 are parallel to each other. The convex plate 24 can be installed on the top of the heat dissipation member 20, and the top surface of the heat dissipation member 20 supports the light source plate 30, which can dissipate heat from the light source plate 30 and extend the service life of the light source plate 30. The two convex plates 24 are positioned on both sides of the light source plate 30 to ensure the stable mounting of the light source plate 30. When the light source plate 30 is mounted in the mounting groove 21, it has a certain friction force between the convex plates 24 and can avoid coming out of the mounting groove 21 during transportation.

[0030] Specifically, in order to improve the stability of the attachment of the light source plate 30, a stop bar 25 is further provided on the top of each protruding plate 24, and the stop bar 25 is used to regulate the position of the top of the light source plate 30. The stop bar 25 is fitted into the top surface of the protruding plate 24 and the heat dissipation member 20, realizing the positioning of the light source plate 30 relative to the periphery and preventing the light source plate 30 from coming out.

[0031] When specifically implemented, the fixing sheet 14 is not only attached to the side of the heat dissipation member 20, but also to the side of the protruding plate 24, thereby increasing the contact area with the heat dissipation member 20 and improving the stability of the installation of the heat dissipation member 20.

[0032] In the present embodiment, the terms "top" and "bottom" refer to the same directions as shown in FIG.

[0033] In one specific embodiment of the fixing sheet 14, the fixing sheet 14 is fixed to the uppermost convex rib 13 to form an integral unit, or the fixing sheet 14 is adhesively fixed to the convex rib 13, and the fixing sheet 14 extends diagonally upward on the side of the convex rib 13 that faces away from the side wall of the outer tube 10, and the fixing sheet 14, the convex rib 13 and the outer tube 10 can be integrally molded, and the same or different materials can be used as long as the light reflection effect of the fixing sheet 14 can be guaranteed.

[0034] In some embodiments, an improved embodiment of the heat dissipation member 20 may adopt a structure as shown in Fig. 4 and Fig. 6. Referring to Fig. 4 and Fig. 6, the heat dissipation member 20 is provided with a connection hole 26 having both ends and a side wall open. When the outer tube 10 is assembled into a lamp in the later stage, it is necessary to attach a closing member 50 to both ends, and a connecting member 54 may be installed on the closing member 50, and the connecting member 54 is inserted into the connecting hole 26 through the closing member 50. The connecting member 54 may be a bolt, a bolt, or the like. In the process of screwing the connecting member 54 into the connecting hole 26, an opening is provided on the side wall of the connecting hole 26, so that a slight deformation may occur in the process of screwing the connecting member 54, which facilitates the installation of the connecting member 54 and simplifies the difficulty of assembly.

[0035] For a more aesthetic appearance, a countersunk hole 53 is provided in the closure member 50 , and the connecting member 54 fits into the countersunk hole 53 and does not protrude from the end face of the closure member 50 remote from the light source plate 30 .

[0036] Based on the same inventive idea, an embodiment of the present invention further provides a tube lamp, which includes the above lampshade.

[0037] The tube lamp further includes a light source plate 30, a driving plate 40 and two closing members 50, the light source plate 30 is installed in the mounting groove 21, the driving plate 40 is installed in the outer tube 10, and the driving plate 40 is electrically connected to the light source plate 30. The two closing members 50 are installed on both ends of the outer tube 10, and each closing member 50 enters the inside of the outer tube 10 and is connected to the heat dissipation member 20. The end face of the closing member 50 is flush with the end face of the outer tube 10. The closing member 50 has a connection pin 51 electrically connected to the driving plate 40.

[0038] Specifically, when the driving plate 40 is attached, the locking groove 12 is formed by being surrounded by the ridges 13 in the outer tube 10, and the driving plate 40 is engaged and fitted into the locking groove 12. The locking groove 12 and the first sliding groove 11 each penetrate the outer tube 10 along the axial direction, so that the heat dissipation member 20 or the driving plate 40 only needs to be inserted into one end of the outer tube 10 during attachment.

[0039] The mounting groove 21 also penetrates the outer tube 10 along the axial direction, and the light source plate 30 is also mounted in the mounting groove 21 so as to be pressed in.

[0040] As for the tube lamp provided in this embodiment, compared with the prior art, when viewed from the front, the length of the outer tube 10 of the lamp is equal to the entire length of the lamp, and when viewed from the side, the closure member 50 is enclosed in the outer tube 10. Therefore, for a 1.2 meter specification lamp, it is only necessary to select a 1.2 meter outer tube 10, which increases the light emission area, optimizes the lighting effect, and provides a more beautiful appearance.

[0041] In some embodiments, one specific fitting form of the closure member 50 and the outer tube 10 can adopt the structure shown in Figures 2, 4, 7, 9 and 11. Referring to Figures 2, 4, 7, 9 and 11, a position limiting groove 52 is provided at the end of the closure member 50 facing the driving plate 40, and a rib is provided in the outer tube 10, which is engaged and fitted into the position limiting groove 52. When the closure member 50 is installed, the rib on the inner wall of the outer tube 10 enters the position limiting groove 52, which can position the closure member 50 and prevent the closure member 50 from rotating in the circumferential direction, making the closure member 50 more stable and less likely to shift after installation.

[0042] If the length of one of the protrusions 13 is increased to form a rib during the molding process, the structure of the outer pipe 10 can be simplified compared to when another rib is additionally installed in addition to installing multiple protrusions 13, making it easier to manufacture the outer pipe 10.

[0043] In some embodiments, an improved embodiment of the closing member 50 may adopt a structure as shown in Figures 2, 7, 9 and 11. Referring to Figures 2, 7, 9 and 11, an abutting portion 55 is provided on the side of the closing member 50 facing the heat dissipation member 20, and the abutting portion 55 abuts on an end face of the heat dissipation member 20. When two closing members 50 are attached to both ends of the outer tube 10, the abutting portion 55 of one of the closing members 50 abuts on one end of the heat dissipation member 20, and the abutting portion 55 of the other closing member 50 abuts on the other end of the heat dissipation member 20, thereby fixing the heat dissipation member 20 and preventing the heat dissipation member 20 from swinging along the axial direction of the outer tube 10.

[0044] In some embodiments, one improved embodiment of the closing member 50 can adopt a structure as shown in Figures 7 to 8. Referring to Figures 7 to 8, the closing member 50 has an end cap 56 extending from the outer tube 10, the end cap 56 abuts against the end surface of the outer tube 10, and the outer circumferential surface of the end cap 56 is flush with the outer circumferential surface of the outer tube 10. Since the closing member 50 is packed inside the outer tube 10, the thickness of the end cap 56 is set as thin as possible, and by setting the end cap 56, the depth to which the closing member 50 penetrates into the outer tube 10 during installation can be limited.

[0045] In order to reduce the step due to manufacturing precision, a joint sealant can be installed between the end cap 56 and the outer tube 10, or the diameter of the end cap 56 can be slightly smaller than the outer diameter of the outer tube 10.

[0046] In some embodiments, an improved embodiment of the closing member 50 may adopt the structure shown in Figures 9 to 10. Referring to Figures 9 to 10, a protruding edge 57 is provided on the outer circumferential surface of the closing member 50, the end of the outer tube 10 has a groove that matches the protruding edge 57, the protruding edge 57 is located in the groove, and the outer circumferential surface of the protruding edge 57 is flush with the outer circumferential surface of the outer tube 10. The protruding edge 57 is not provided on the entire outer circumferential surface of the closing member 50, but is provided on half the outer circumferential surface of the closing member 50, for example, the protruding edge 57 is provided on half the outer circumferential surface of the closing member 50, and the protruding edge 57 is not provided on the other half, so that the outer tube 10 can be extended and the light-emitting area can be made larger, and the protruding edge 57 is provided corresponding to the groove on the outer tube 10, and further, the error-proofing can be realized during the installation process of the closing member 50, and it is ensured that the connecting member 54 on the closing member 50 corresponds to the connecting hole 26 on the heat dissipation member 20 after installation.

[0047] In order to reduce the step caused by manufacturing precision, a joint sealant can be installed between the tongue 57 and the outer pipe 10, or the diameter of the tongue 57 can be slightly smaller than the outer diameter of the outer pipe 10.

[0048] In some embodiments, one improved embodiment of the closure member 50 may adopt a structure as shown in Figures 11 to 12. Referring to Figures 11 to 12, an edge cover 58 is provided at the end of the closure member 50 away from the outer tube 10, and the edge cover 58 is fitted around the outer periphery of the outer tube 10. Since the closure member 50 is packed inside the outer tube 10, the thickness of the edge cover 58 is set as thin as possible. By setting the edge cover 58, the installation of the closure member 50 can be made more secure, and the width of the edge cover 58 can exceed half or more of the exposed thickness of the closure member 50.

[0049] In some embodiments, one improved fitting form of the driving plate 40 and the closing member 50 can adopt a structure as shown in Fig. 2. Referring to Fig. 2, a through hole 41 is provided in the driving plate 40, and a hook 59 that fits into the through hole 41 is provided at the end of the closing member 50 facing the driving plate 40. When the closing member 50 is installed, the hook 59 is hooked into the through hole 41 to hang the driving plate 40, which restricts the driving plate 40 from moving in the axial direction of the outer tube 10 and improves the stability of the assembly.

[0050] In some embodiments, one specific electrical connection form of the driving plate 40 can adopt the following structure. Although not shown, the input line and the output line of the driving plate 40 are on the same side. The input line is bent into an L shape using a hard metal wire and inserted into the driving plate 40 by an automated device, and the other end contacts the connection pin 51 of the closing member 50 to achieve electrical connection. The hard metal wire can be a copper wire, a copper-coated steel wire, an aluminum-coated steel wire, etc. The hard metal wire is easier to insert into the connection pin 51 than a flexible power line, improving assembly efficiency.

[0051] In addition, the female terminal on the light source plate 30 is welded to the light source plate 30 by a reflow soldering sheet, and the input wire on the light source plate 30 adopts a double-layer insulated wire, or a sleeve is added to the input wire for protection, thereby preventing the input wire from being cracked or scratched at the bent corner.

[0052] The above description is merely a preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
