[0020] In the claims, specification and drawings of the present invention, when the terms "including", "having" and variations thereof are used, it is intended to mean "including but not limited to".

[0021] 1 to 5 and 7 to 12, the lamp housing module provided by the present invention will be described below. The lamp housing module includes an outer tube 10 and two closing members 50, the two closing members 50 are installed on both ends of the outer tube 10, each closing member 50 enters the inside of the outer tube 10 and is connected to the outer tube 10, and the end face of the closing member 50 is flush with the end face of the outer tube 10.

[0022] Compared with the prior art, in the lamp case module provided in this embodiment, after the light source plate 30 is installed in the lamp case module, the length of the formed lamp is equal to that of the outer tube 10 when viewed from the front, and the closing member 50 is enclosed within the outer tube 10 when viewed from the side, so that a 1.2 meter specification lamp can select a 1.2 meter outer tube 10, which increases the light emitting area, looks more beautiful from the outside, and has a larger light emitting area when used, optimizing the lighting effect.

[0023] In some embodiments, one specific embodiment of the fitting between the outer tube 10 and the closing member 50 may adopt the structure shown in Figures 1 and 4. Referring to Figures 1 and 4, a connecting hole 26 is provided in the outer tube 10, a connecting member 54 is fitted into the closing member 50, and the connecting member 54 penetrates the closing member 50 and fits into the connecting hole 26. The connecting member 54 may be a bolt, a bolt, or the like. Fixing the closing member 50 with the connecting member 54 ensures the reliability of the installation of the closing member 50 and makes it easy to remove the closing member 50.

[0024] During actual installation, the connection hole 26 may be formed on the inner wall of the outer tube 10, or the heat dissipation member 20 may be attached inside the outer tube 10. When the connection hole 26 is formed in the heat dissipation member 20, the connection hole 26 may have a structure in which both ends and side walls are open. During the process of the connection member 54 being screwed into the connection hole 26, openings are provided on the side walls of the connection hole 26, so that slight deformation can occur during the process of the connection member 54 being screwed, which facilitates the installation of the connection member 54 and reduces the difficulty of assembly.

[0025] For a more aesthetic appearance, the closure member 50 is provided with a countersunk hole 53, and the connecting member 54 fits into the countersunk hole 53 and does not protrude from the end face of the closure member 50 away from the space inside the outer tube 10.

[0026] In some embodiments, one improved fitting form of the above-mentioned 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 space inside the outer tube 10, and a rib is provided inside 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 slip after installation.

[0027] In some embodiments, one specific embodiment of the outer tube 10 may adopt the structure shown in Figures 4 to 5. Referring to Figures 4 to 5, a plurality of ridges 13 are protruded from the inner wall of the outer tube 10, and the space between two adjacent ridges 13 forms a functional groove, and one of the ridges 13 forms a rib. For example, the plurality of ridges 13 form a first sliding groove 11 and a locking groove 12, and the first sliding groove 11 and the locking groove 12 are both called functional grooves, and the first sliding groove 11 is used to mount the heat dissipation member 20, and the locking groove 12 is used to mount the driving plate 40.

[0028] The first sliding groove 11 and the locking groove 12 are formed by installing the ridges 13. Compared with directly drilling a groove on the inner wall of the outer tube 10, this embodiment allows the selection of a thinner outer tube 10, which not only improves the brightness of the light, but also reduces the amount of molding material used for the outer tube 10, thereby saving costs; by lengthening one of the ridges 13 during the molding process and forming an additional rib, the structure of the outer tube 10 can be simplified and the manufacture of the outer tube 10 can be facilitated, compared with installing multiple ridges 13 and installing another rib.

[0029] In a specific implementation, three or four convex strips 13 can be installed. When the number of convex strips 13 is three, the space between every two adjacent convex strips 13 forms one sliding groove; when the number of convex strips 13 is four, the space between two adjacent convex strips 13 forms a first sliding groove 11, and the space between the other two adjacent convex strips 13 forms a locking groove 12.

[0030] In some embodiments, one improved embodiment of the above-mentioned closing member 50 can adopt the structure shown in Figures 2, 7, 9 and 11. Referring to Figures 2, 7, 9 and 11, an abutment portion 55 is provided at the end of the closing member 50 facing the space inside the outer tube 10. The closing member 50 is used to abut and fix the internal components of the outer tube 10 after installation. For example, after the heat dissipation member 20 is installed in the outer tube 10, the abutment portions 55 of the two closing members 50 abut against the two end faces of the heat dissipation member 20, preventing the heat dissipation member 20 from swinging along the axial direction of the outer tube 10.

[0031] In some embodiments, one improved embodiment of the closure member 50 can adopt a structure as shown in Figures 7 to 8. Referring to Figures 7 to 8, the closure 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 closure member 50 is packed inside the outer tube 10, the thickness of the end cap 56 can be set as thin as possible, and by setting the end cap 56, the depth to which the closure member 50 penetrates into the outer tube 10 during installation can be limited.

[0032] 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.

[0033] 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, an 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 circumference, for example, the protruding edge 57 is provided on one half circumference and not provided on the other half circumference, so that the outer tube 10 can be extended and the light can be more complete. The protruding edge 57 is installed correspondingly with the groove on the outer tube 10, which can further realize the error proofing during the installation of the closing member 50, and ensure that the connecting member 54 on the closing member 50 corresponds to the connecting hole 26 on the heat dissipation member 20 after installation.

[0034] 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.

[0035] In some embodiments, one improved embodiment of the closure member 50 can 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 can be set as thin as possible. By providing 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.

[0036] In some embodiments, one improved fitting form of the driving plate 40 and the closing member 50 can adopt the structure shown in Figures 2, 4, 7, 9 and 11. Referring to Figures 2, 4, 7, 9 and 11, a hook 59 is provided at the end of the closing member 50 facing the space inside the outer tube 10. The hook 59 can be hooked to a component inside the outer tube 10, improving the integrity and being more stable after installation. For example, when a through hole 41 is provided on the driving plate 40 and the closing member 50 is installed, the hook 59 can be hooked to the through hole 41 to hang the driving plate 40, restricting the driving plate 40 from moving in the axial direction of the outer tube 10 and improving the stability of the assembly.

[0037] Based on the same inventive idea, the present invention further provides a tube lamp, which includes the above lamp housing module.

[0038] The tube lamp further includes a heat dissipation member 20, a light source plate 30 and a driving plate 40, the heat dissipation member 20 is mounted in the outer tube 10, a mounting groove 21 is provided in the heat dissipation member 20, the light source plate 30 is mounted in the mounting groove 21, the driving plate 40 is mounted in the outer tube 10, the driving plate 40 is electrically connected to the light source plate 30, each closing member 50 is connected to the heat dissipation member 20, and the closing member 50 has a connection pin 51 electrically connected to the driving plate 40.

[0039] As described above, the first sliding groove 11 and the locking groove 12 are provided inside the outer tube 10, and the heat dissipation member 20 is slidably fitted into the first sliding groove 11, and the drive plate 40 is engaged and fitted into the locking groove 12.

[0040] Both the first sliding groove 11 and the locking groove 12 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 from one end of the outer tube 10 during installation.

[0041] The mounting groove 21 also penetrates the outer tube 10 along the axial direction, and the light source plate 30 is also mounted by being pressed into the mounting groove 21 .

[0042] In some embodiments, one improved embodiment of the outer tube 10 may adopt the structure shown in Figures 4 to 5. Referring to Figures 4 to 5, fixing sheets 14 are protruded from opposite sides of the inner wall of the outer tube 10, and the two fixing sheets 14 are both attached to the heat dissipation member 20. The fixing sheets 14 are attached to the heat dissipation member 20 to not only improve the stability of the heat dissipation member 20, but also, when the light source plate 30 emits light, the light is reflected by the fixing sheets 14, which improves the optical reflection effect and the optical effect of the entire lighting fixture.

[0043] Please refer to FIG. 4 for specific light reflection diagram.

[0044] As a specific embodiment of the fixing sheet 14, the fixing sheet 14 can be formed by extending the topmost convex strip 13 diagonally upward. As long as the light reflection effect of the fixing sheet 14 can be guaranteed, the fixing sheet 14, the convex strip 13 and the outer tube 10 can be integrally molded, and the same or different materials can be used.

[0045] 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 spaced apart below the first sliding bar 22, 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.

[0046] In some embodiments, one specific 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 is provided with two convex plates 24 spaced apart from each other, 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 the light source plate 30, which can avoid it coming out of the mounting groove 21 during transportation.

[0047] Specifically, in order to improve the stability of the installation of the light source plate 30, a stop bar 25 is further installed on the top of each convex plate 24, and the stop bar 25 limits the position of the top of the light source plate 30. The stop bar 25, the convex plate 24 and the top surface of the heat dissipation member 20 can form a fitting space, which realizes positioning relative to the periphery of the light source plate 30 and prevents the light source plate 30 from protruding.

[0048] When specifically implemented, the fixing sheet 14 is not only attached to the side of the heat dissipation member 20, but also attached 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.

[0049] In the present embodiment, the terms "top" and "bottom" refer to the same directions as shown in FIG.

[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 realize the electrical connection. The hard metal wire can be a copper wire, a copper-coated steel wire, an aluminum-coated steel wire, etc., and the hard metal wire is easier to insert into the connection pin 51 than a flexible power line, improving the 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 is protected by an additional sleeve to prevent the input wire from being cracked or scratched at the bent corner.
