[0039] Please see Figures 1 to 5 、 Figures 7 to 12 , the lamp shell module provided by the utility model will be described. The lamp shell module comprises an outer pipe 10 and two sealing members 50, the two sealing members 50 are arranged at two ends of the outer pipe 10, each sealing member 50 extends into the inside of the outer pipe 10 and is connected with the outer pipe 10, the end face of the sealing member 50 is flush with the end face of the outer pipe 10

[0040] Compared with the prior art, the lamp shell module provided in the embodiment forms a lamp from the front, and the length of the outer pipe 10 is equal to the length of the whole lamp, and from the side, the sealing member 50 is wrapped in the outer pipe 10, so that a 1.2-meter specification lamp can select a 1.2-meter outer pipe 10, the light-emitting area is increased, it is more beautiful from the outside, the light-emitting area is also larger in use, and the lighting effect is optimized.

[0041] In some embodiments, a specific cooperation implementation mode of the above outer pipe 10 and sealing member 50 can adopt the structure shown in Figure 1 and Figure 4 . Referring to Figure 1 and Figure 4The outer tube 10 is provided with a connecting hole 26, the sealing member 50 is provided with a connecting member 54, and the connecting member 54 penetrates the sealing member 50 and is matched with the connecting hole 26. The connecting member 54 can be a bolt or a bolt, and the sealing member 50 is fixed through the connecting member 54, which ensures the installation reliability of the sealing member 50 and facilitates the disassembly of the sealing member 50.

[0042] In actual installation, a connecting hole 26 can be formed on the inner wall of the outer tube 10, or a heat dissipation member 20 can be installed in the outer tube 10, and a connecting hole 26 is formed on the heat dissipation member 20. The connecting hole 26 can be a structure with openings at both ends and the side wall. During the process of screwing the connecting member 54 into the connecting hole 26, the side wall of the connecting hole 26 is provided with an opening, so that the connecting member 54 can be slightly deformed during the screwing process, which facilitates the installation of the connecting member 54 and simplifies the assembly difficulty.

[0043] In order to be more beautiful, the sealing member 50 is provided with a counterbore 53, and the connecting member 54 extends into the counterbore 53 and does not protrude from the end face of the sealing member 50 away from the space in the outer tube 10.

[0044] In some embodiments, the improved cooperation between the sealing member 50 and the outer tube 10 can adopt the structure as shown in Figure 2 、 Figure 4 、 Figure 7 、 Figure 9 、 Figure 11 . Figure 2 、 Figure 4 、 Figure 7 、 Figure 9 、 Figure 11 The end of the sealing member 50 facing the space in the outer tube 10 is provided with a limiting groove 52, and the inner wall of the outer tube 10 is provided with a rib matched with the limiting groove 52. After the sealing member 50 is installed, the rib on the inner wall of the outer tube 10 extends into the limiting groove 52, which can position the sealing member 50 and prevent the sealing member 50 from being twisted in the circumferential direction, so that the installed sealing member 50 is more stable and less likely to be moved.

[0045] In some embodiments, a specific embodiment of the above-mentioned outer tube 10 can adopt the structure as shown in Figures 4 to 5 . Figures 4 to 5 The inner wall of the outer tube 10 is provided with a plurality of convex strips 13, and the space between adjacent two convex strips 13 forms a functional groove, and one of the convex strips 13 forms a rib. For example, a plurality of convex strips 13 form a first sliding groove 11 and a clamping groove 12, and the first sliding groove 11 and the clamping groove 12 are collectively referred to as a functional groove. The first sliding groove 11 is used for installing the heat dissipation member 20, and the clamping groove 12 is used for installing the driving plate 40.

[0046] The first sliding groove 11 and the clamping groove 12 are formed by arranging the protrusions 13. Compared with directly opening grooves on the inner wall of the outer tube 10, the embodiment can use an outer tube 10 with a thinner thickness. The brightness of the illumination can be enhanced, and the use amount of the forming material of the outer tube 10 can be reduced, thereby saving costs. By increasing the length of one of the protrusions 13 during the forming process to form a rib, compared with arranging a rib additionally on the basis of arranging a plurality of protrusions 13, the structure of the outer tube 10 can be simplified, and the manufacturing of the outer tube 10 is facilitated.

[0047] In specific implementation, the protrusions 13 can be arranged as three or four. When the number of the protrusions 13 is three, the space between each adjacent two protrusions 13 forms a sliding groove. When the number of the protrusions 13 is four, the space between two adjacent protrusions 13 forms the first sliding groove 11, and the space between the other two adjacent protrusions 13 forms the clamping groove 12.

[0048] In some embodiments, an improved embodiment of the plugging member 50 can adopt a structure as shown in Figure 2 、 Figure 7 、 Figure 9 、 Figure 11 . Referring to Figure 2 、 Figure 7 、 Figure 9 、 Figure 11 , one end of the plugging member 50 towards the inner space of the outer tube 10 is provided with an abutting portion 55. After the plugging member 50 is installed, the abutting portion 55 is used to abut and fix the parts inside the outer tube 10. For example, after the heat dissipation member 20 is installed in the outer tube 10, the abutting portions 55 on the two plugging members 50 abut the two end faces of the heat dissipation member 20, so as to avoid the heat dissipation member 20 from shaking along the axial direction of the outer tube 10.

[0049] In some embodiments, an improved embodiment of the plugging member 50 can adopt a structure as shown in Figures 7 to 8 . Referring to Figures 7 to 8 , the plugging member 50 has an end cover 56 extending out of the outer tube 10. The end cover 56 abuts the end face of the outer tube 10, and the outer peripheral surface of the end cover 56 is flush with the outer peripheral surface of the outer tube 10. Because the plugging member 50 is inserted into the inner part of the outer tube 10, the thickness of the end cover 56 can be set as narrow as possible. By arranging the end cover 56, the length of the plugging member 50 extending into the outer tube 10 during installation can be limited.

[0050] In order to reduce the step difference caused by manufacturing precision, an aesthetic joint can be arranged between the end cover 56 and the outer tube 10, or the diameter of the end cover 56 is slightly smaller than the outer diameter of the outer tube 10.

[0051] In some embodiments, a deformed embodiment of the plugging member 50 can adopt a structure as shown in Figures 9 to 10 . Referring to Figures 9 to 10The outer peripheral surface of the blocking piece 50 is provided with a protruding edge 57, the end of the outer tube 10 is provided with a groove matched with the protruding edge 57, the protruding edge 57 is located in the groove, and the outer peripheral surface of the protruding edge 57 is flush with the outer peripheral surface of the outer tube 10. The protruding edge 57 is not provided in a whole circle on the outer periphery of the blocking piece 50, for example, half of the circle is provided with the protruding edge 57, and the other half of the circle is not provided with the protruding edge 57, so that the outer tube 10 can be extended outward, and the light emission can be more integral; the protruding edge 57 is matched and installed with the groove on the outer tube 10, and the installation process of the blocking piece 50 can be prevented from being mistaken, so that the connecting piece 54 on the blocking piece 50 is matched with the connecting hole 26 on the heat dissipation piece 20 after installation.

[0052] In order to reduce the step caused by manufacturing precision, an aesthetic seam can be arranged between the protruding edge 57 and the outer tube 10, or the diameter of the protruding edge 57 is slightly smaller than the outer diameter of the outer tube 10.

[0053] In some embodiments, a variant of the blocking piece 50 can adopt the structure as shown in Figures 11 to 12 . As shown in Figures 11 to 12 , the end of the blocking piece 50 away from the outer tube 10 is provided with a cover 58, and the cover 58 is sleeved on the outer periphery of the outer tube 10. Because the blocking piece 50 is inserted into the inner part of the outer tube 10, the thickness of the cover 58 can be as small as possible, and the installation of the blocking piece 50 can be more reliable by arranging the cover 58, and the width of the cover 58 can be more than one half of the exposed thickness of the blocking piece 50.

[0054] In some embodiments, an improved matching mode of the above-mentioned driving plate 40 and the blocking piece 50 can adopt the structure as shown in Figure 2 , Figure 4 , Figure 7 , Figure 9 , Figure 11 . As shown in Figure 2 , Figure 4 , Figure 7 , Figure 9 , Figure 11 , the end of the blocking piece 50 facing the inner space of the outer tube 10 is provided with a hook 59. The hook 59 can be hung with parts in the inner part of the outer tube 10, improve the integrity, and be more stable after installation; for example, the driving plate 40 is provided with a perforation 41, the hook 59 is hung on the perforation 41 after the blocking piece 50 is installed, the driving plate 40 can be hung, the movement of the driving plate 40 in the axial direction of the outer tube 10 is limited, and the stability of assembly is improved.

[0055] Based on the same inventive concept, the utility model also provides a pipe type lamp, which comprises the lamp shell module.

[0056] The tube type lamp tube further comprises a heat dissipation piece 20, a light source plate 30, and a driving plate 40. The heat dissipation piece 20 is installed in the outer tube 10, and the heat dissipation piece 20 is provided with an installation groove 21. The light source plate 30 is arranged in the installation groove 21. The driving plate 40 is arranged in the outer tube 10, and the driving plate 40 is electrically connected with the light source plate 30. Each blocking piece 50 is connected with the heat dissipation piece 20, and the blocking piece 50 is provided with a connecting pin 51 which is electrically connected with the driving plate 40.

[0057] It has been introduced above that the outer tube 10 is provided with a first sliding groove 11 and a clamping groove 12. The heat dissipation piece 20 is slidingly fitted in the first sliding groove 11, and the driving plate 40 is clampingly fitted in the clamping groove 12.

[0058] It should be noted that the first sliding groove 11 and the clamping groove 12 are both through the axial direction of the outer tube 10, so that when the heat dissipation piece 20 or the driving plate 40 is installed, it only needs to be inserted from one end of the outer tube 10.

[0059] In addition, the installation groove 21 is also through the axial direction of the outer tube 10, and the light source plate 30 is also installed in the installation groove 21 in a pushing manner.

[0060] In some embodiments, an improved embodiment of the above-mentioned outer tube 10 can adopt a structure as shown in Figures 4 to 5 . Referring to Figures 4 to 5 , opposite sides of the inner wall of the outer tube 10 are provided with fixing pieces 14, and the two fixing pieces 14 are attached to the heat dissipation piece 20. The fixing pieces 14 not only can be attached to the heat dissipation piece 20 to improve the stability of the heat dissipation piece 20, but also can reflect light when the light source plate 30 emits light, thereby enhancing the optical reflection effect and improving the optical effect of the entire lamp.

[0061] Specifically, the light reflection diagram is shown in Figure 4 .

[0062] As a specific embodiment of the fixing piece 14, the topmost protruding strip 13 can be inclined to extend upward to form the fixing piece 14. The fixing piece 14, the protruding strip 13, and the outer tube 10 can be integrally formed and can be made of the same material or different materials, but the light reflection effect of the fixing piece 14 should be ensured.

[0063] In some embodiments, an improved embodiment of the above-mentioned heat dissipation piece 20 can adopt a structure as shown in Figure 4 and Figure 6 . Referring to Figure 4 and Figure 6The heat dissipation member 20 has a first sliding strip 22 matched with the first sliding groove 11, and has a second sliding strip 23 located below the first sliding strip 22. The first sliding strip 22 and the second sliding strip 23 enclose a second sliding groove in which one of the protrusions 13 is slidingly matched. Through the matching of the first sliding strip 22 with the first sliding groove 11 and the matching of one of the protrusions 13 with the second sliding groove, the heat dissipation member 20 can be limited in the up-down direction, avoiding the sliding of the heat dissipation member 20 to affect the light emitting effect of the light source plate 30.

[0064] In some embodiments, one specific implementation of the heat dissipation member 20 described above can adopt the structure as shown in Figure 4 and Figure 6 . Referring to Figure 4 and Figure 6 , the heat dissipation member 20 is provided with two protruding plates 24 arranged at intervals. The space between the two protruding plates 24 forms the mounting groove 21 described above. The plate surface of the protruding plate 24 is parallel to the axial direction of the outer tube 10, and the two protruding plates 24 are parallel to each other. The protruding plate 24 can be arranged at the top of the heat dissipation member 20. The top surface of the heat dissipation member 20 supports the light source plate 30 to dissipate heat for the light source plate 30, thereby prolonging the service life of the light source plate 30. The two protruding plates 24 are positioned on both sides of the light source plate 30 to ensure the stable installation of the light source plate 30. After the light source plate 30 is mounted into the mounting groove 21, there is a certain friction force between the light source plate 30 and the protruding plate 24, which can prevent the light source plate 30 from falling out of the mounting groove 21 during transportation.

[0065] Specifically, in order to improve the installation stability of the light source plate 30, the top of each protruding plate 24 is further provided with a blocking strip 25. The blocking strip 25 limits the top of the light source plate 30. The blocking strip 25 cooperates with the top surface of the protruding plate 24 and the heat dissipation member 20 to realize the positioning of the light source plate 30 around, thereby preventing the light source plate 30 from falling out.

[0066] In a specific implementation, the fixing sheet 14 not only fits the side surface of the heat dissipation member 20, but also fits the side surface of the protruding plate 24, thereby increasing the contact area with the heat dissipation member 20 and improving the installation stability of the heat dissipation member 20.

[0067] In the embodiments of the present application, the terms "top" and "bottom" are the same as the directions indicated in Figure 4 .

[0068] In some embodiments, one specific electrical connection mode of the driving plate 40 described above can adopt the structure as described below. The input line and the output line on the driving plate 40 are located on the same side. The input line is made of hard metal bare wire and is folded into an L shape. The input line is inserted into the driving plate 40 by an automatic equipment, and the other end is in contact with the connecting pin 51 on the plugging member 50 to realize electrical connection. The hard metal bare wire can be copper, copper-coated steel, aluminum-coated steel, etc. Compared with the flexible power line, the hard metal bare wire is easier to be inserted into the connecting pin 51, thereby improving the assembly efficiency.

[0069] It should be noted that the female terminals on the light source board 30 are reflow soldered on the light source board 30, and the input lines on the light source board 30 adopt double-layer insulated wires or are protected by adding sleeves to prevent the wires from being cut or scratched at the folding angle.

[0070] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
