Abstract
Description
Technical Field
[0001] This application belongs to the field of lighting equipment technology, and more specifically, relates to a fluorescent tube. Background Technology
[0002] Fluorescent tubes typically consist of a tube and lamp holders at both ends. The lamp holders need to be connected to a power source, while the tube guides the light. The assembly of the lamp holders and tube is a crucial step in the manufacturing process of fluorescent tubes. However, existing assembly processes face a common problem: due to manufacturing tolerances, the fit between the lamp holder and tube is difficult to control precisely.
[0003] Specifically, if the lamp holder and the lamp tube fit too tightly, excessive stress may be generated during assembly. This not only increases the difficulty of assembly but also easily causes the lamp holder to crack due to uneven stress, thus affecting the overall lifespan and safety of the lamp tube. Conversely, if the fit is too loose, although the assembly process is relatively easy, the lamp holder is prone to detaching from the lamp tube during use due to vibration or external force. This not only causes lighting interruption but may also pose safety hazards such as electric shock. Utility Model Content
[0004] The purpose of this application is to provide a fluorescent tube to solve the technical problem of poor fit between the lamp holder and the tube in the prior art.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] A fluorescent tube is provided, comprising:
[0007] fluorescent tube;
[0008] The lamp holder is fitted onto both ends of the lamp tube;
[0009] The snap-fit structure includes a snap hole and an elastic snap flap. The snap hole is located on one of the lamp tube and the lamp holder, and the elastic snap flap is located on the other of the lamp tube and the lamp holder. The elastic snap flap has a snap-fit protrusion. When the snap-fit protrusion is engaged with the snap hole, the lamp holder is snapped onto the end of the lamp tube.
[0010] As a further improvement to the above technical solution:
[0011] Optionally, the elastic flap includes a fixed end and a movable end. The fixed end of the elastic flap is connected to the lamp tube or the lamp head and is an integral structure with the lamp tube or the lamp head. A clearance gap is provided between the movable end of the elastic flap and the lamp tube or the lamp head.
[0012] Optionally, the number of elastic latches is at least two, and each elastic latch is arranged at intervals along the circumference of the lamp tube; the number and position of the latch holes correspond to the elastic latches.
[0013] Optionally, the inner side of the lamp tube is provided with a first limiting protrusion, the first limiting protrusion protruding from the inner wall of the lamp tube toward the center of the lamp tube, and the first limiting protrusion extending along the axial direction of the lamp tube; the inner side of the lamp holder is provided with a first limiting slot, and when the lamp holder is sleeved on the lamp tube, the first limiting protrusion is inserted into the first limiting slot.
[0014] Optionally, the number of the first limiting protrusions is at least two, and each of the first limiting protrusions is arranged at intervals along the circumference of the lamp tube; the number and position of the first limiting slots correspond to the first limiting protrusions.
[0015] Optionally, the fluorescent tube further includes a heat sink disposed in the tube. The heat sink includes a second limiting slot that extends along the axial direction of the tube, and a first limiting protrusion is inserted into the second limiting slot.
[0016] Optionally, the heat sink further includes a third limiting slot, and the inner side of the lamp head also has a second limiting protrusion, which protrudes along the axial direction of the lamp tube; when the lamp head is sleeved on the lamp tube, the second limiting protrusion is inserted into the third limiting slot.
[0017] Optionally, the number of the second limiting protrusions is at least two, and each of the second limiting protrusions is arranged at intervals from each other along the circumference of the lamp head; the number and position of the third limiting slots correspond to the second limiting protrusions.
[0018] Optionally, the fluorescent tube includes an illumination module connected to one side of the heat sink.
[0019] Optionally, the fluorescent tube also includes a power supply assembly connected to the other side of the heat sink and electrically connected to the lighting module.
[0020] The beneficial effects of the fluorescent tube provided in this application are as follows:
[0021] The fluorescent tube provided in this application includes a tube and a lamp holder, which are connected by a snap-fit structure. The tube is a cover that covers the outside of the lighting module and is translucent, ensuring that light can penetrate evenly and efficiently to illuminate the surrounding environment. The lamp holder is fitted over the openings at both ends of the tube, responsible for sealing the openings at both ends of the tube. It not only isolates the tube from the internal and external environments but also serves as a connection to the power supply. The snap-fit structure specifically includes a locking hole and a flexible locking flap. The locking hole is located on the tube, and the flexible locking flap is located on the lamp holder; alternatively, the locking hole may be located on the lamp holder, and the flexible locking flap may be located on the tube. The flexible locking flap has a locking protrusion. When the locking protrusion engages with the locking hole, the lamp holder can be securely fitted onto the end of the tube. When assembling the lamp holder and lamp tube, the elastic latch can be pushed outward under its elastic action, so that the lamp holder can be smoothly inserted into the lamp tube. When the latch protrusion engages with the latch hole, the elastic latch returns to its original position, so that the latch protrusion is locked in the latch hole.
[0022] In the fluorescent tube of this application, the assembly of the tube and the lamp holder is not affected by assembly tolerances. The elastic flaps allow the buckle protrusions to smoothly engage with the buckle holes, which not only ensures the stability of the assembly but also avoids the lamp holder from falling off or the tube from being damaged due to improper assembly.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0042] like Figures 1 to 3As shown, this application provides a fluorescent tube, including a tube 1 and a lamp holder 2, which are connected by a snap-fit structure.
[0043] Among them, the lamp tube 1 is a cover placed on the outside of the lighting module 6. It is transparent to ensure that the light can penetrate and illuminate the surrounding environment evenly and efficiently.
[0044] The lamp holder 2 is fitted at both ends of the lamp tube 1 and is responsible for sealing the two ends of the lamp tube 1. It is used not only to isolate the internal and external environment of the lamp tube, but also to connect to the power supply.
[0045] The snap-fit structure specifically includes a snap-fit hole 3 and an elastic snap-fit flap 4. The snap-fit hole 3 is located on the lamp tube 1, and the elastic snap-fit flap 4 is located on the lamp holder 2; alternatively, the snap-fit hole 3 can be located on the lamp holder 2, and the elastic snap-fit flap 4 can be located on the lamp tube 1. The elastic snap-fit flap 4 has a snap-fit protrusion. When the snap-fit protrusion is engaged with the snap-fit hole 3, the lamp holder 2 can be securely snapped onto the end of the lamp tube 1. When assembling the lamp holder 2 and the lamp tube 1, the elastic snap-fit flap 4 can be pushed outward under its elastic action, so that the lamp holder 2 can be smoothly inserted into the lamp tube 1. When the snap-fit protrusion engages with the snap-fit hole 3, the elastic snap-fit flap 4 elastically returns to its original position, so that the snap-fit protrusion is engaged in the snap-fit hole 3.
[0046] In the fluorescent tube of this application, the assembly of the tube 1 and the lamp holder 2 is not affected by the assembly tolerance. The elastic flap 4 allows the buckle protrusion to smoothly engage with the buckle hole 3, which not only ensures the stability of the assembly, but also avoids the lamp holder from falling off or the tube from being damaged due to improper assembly.
[0047] like Figure 3 As shown in a specific embodiment of this application, the elastic flap 4 includes a fixed end and a movable end. The fixed end of the elastic flap 4 is connected to the lamp tube 1 or the lamp holder 2 and is an integral structure with the lamp tube 1 or the lamp holder 2 to improve the connection strength and stability of the overall structure. A clearance gap is provided between the movable end of the elastic flap 4 and the lamp tube 1 or the lamp holder 2. The existence of the clearance gap ensures that the movable end can smoothly push outwards or open when subjected to external force, thereby facilitating assembly.
[0048] In one specific embodiment of this application, the number of elastic latches 4 is at least two. Increasing the number of elastic latches 4 further enhances the stability of the connection between the lamp tube 1 and the lamp holder 2. The elastic latches 4 are arranged at intervals along the circumference of the lamp tube 1, ensuring uniform force distribution among the elastic latches 4 and effectively dispersing stress concentration at the connection point, thereby extending the service life of the lamp. Simultaneously, the number and position of the locking holes 3 correspond to the elastic latches 4. The cooperation between the elastic latches 4 and the locking holes 3 ensures axial positioning between the lamp tube 1 and the lamp holder 2, while preventing circumferential misalignment, thus meeting the various safety regulations regarding torque and tensile force requirements of the lamp tube.
[0049] like Figure 2 and Figure 5 As shown, in a specific embodiment of this application, the inner side of the lamp tube 1 is provided with a first limiting protrusion 11, which protrudes from the inner wall of the lamp tube 1 toward the center of the lamp tube 1 and extends along the axial direction of the lamp tube 1; the inner side of the lamp holder 2 is provided with a first limiting slot 21. When the lamp holder 2 is sleeved on the lamp tube 1, the first limiting protrusion 11 is inserted into the first limiting slot 21 to limit the circumferential direction of the lamp tube 1 and the lamp holder 2, so as to prevent the lamp tube 1 and the lamp holder 2 from twisting or misaligning in the circumferential direction.
[0050] like Figure 2 and Figure 5 As shown, in a specific embodiment of this application, the number of first limiting protrusions 11 is at least two, and each first limiting protrusion 11 is arranged at intervals along the circumference of the lamp tube 1; the number and position of the first limiting slots 21 correspond to the first limiting protrusions 11, further enhancing the connection strength between the lamp tube 1 and the lamp holder 2, and also extending the service life of the lamp by dispersing stress.
[0051] like Figure 5 and Figure 6 As shown, in one specific embodiment of this application, the fluorescent tube further includes a heat sink 5. The heat sink 5 is made of a metal with good thermal conductivity. The heat sink 5 is disposed in the tube 1 and includes a second limiting slot 51. The second limiting slot 51 extends along the axial direction of the tube 1, and a first limiting protrusion 11 is inserted into the second limiting slot 51 to limit the circumferential movement of the tube 1 and the heat sink 5, thereby preventing the tube 1 and the heat sink 5 from twisting or misaligning in the circumferential direction.
[0052] like Figure 5 and Figure 6 As shown, in a specific embodiment of this application, the heat sink 5 further includes a third limiting slot 52, and the inner side of the lamp head 2 also has a second limiting protrusion 22, which protrudes along the axial direction of the lamp tube 1. When the lamp head 2 is sleeved on the lamp tube 1, the second limiting protrusion 22 is inserted into the third limiting slot 52 to limit the circumferential direction of the lamp head 2 and the heat sink 5, so as to prevent the lamp head 2 and the heat sink 5 from twisting or misaligning in the circumferential direction, thereby making the lamp tube 1, the lamp head 2 and the heat sink 5 more stably limited in the circumferential direction.
[0053] like Figure 5 and Figure 6 As shown, in a specific embodiment of this application, the number of second limiting protrusions 22 is at least two, and each second limiting protrusion 22 is arranged at intervals along the circumference of the lamp head 2; the number and position of the third limiting slots 52 correspond to the second limiting protrusions 22, further enhancing the connection strength between the lamp head 2 and the heat sink 5, dispersing the connection stress between the lamp head 2 and the heat sink 5, and extending the service life of the lamp.
[0054] like Figure 4 and Figure 7 As shown, in one specific embodiment of this application, the fluorescent tube includes a lighting module 6, which includes components such as a light strip, connecting terminals, and ribbon cables. The lighting module 6 is connected to one side of a heat sink 5. The heat sink 5 increases the heat dissipation area of the lighting module 6, effectively dissipating the heat generated by the lighting module 6, thereby extending the service life of the fluorescent tube.
[0055] like Figure 7 As shown in one specific embodiment of this application, the fluorescent tube further includes a power supply component 7, which is electrically connected to the lighting module 6. The power supply component 7 can serve as a backup power source, providing continuous power to the lighting module 6 when the external power supply is interrupted. The power supply component 7 is connected to the other side of the heat sink 5 to utilize the space on the other side of the heat sink 5 and to prevent the power supply component 7 from blocking the light generated by the lighting module 6.
[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
