Description

[Technical Field]

[0001] This utility model provides a modular lamp tube structure that utilizes a rotating buckle and anti-reverse tamper-evident design to achieve advantages such as reduced cost, extended service life, ensured safety, and compliance with environmental protection characteristics for ultraviolet light-emitting diodes. [Background Technology]

[0002] Currently, most ultraviolet (UV) light-emitting diode (LED) lamps on the market use glass as their outer casing. This design is primarily based on the material's light transmittance and sealing properties. To seal off toxic gases inside the lamp, adhesive is typically used to bond the glass tubes together. This encapsulation method effectively prevents leakage of toxic gases, but it also introduces some problems.

[0003] First, while glass possesses excellent optical properties, its brittleness makes the lamp tubes prone to breakage during transportation or installation, posing a potential hazard to users. Furthermore, although colloids provide a sealing effect, prolonged use may lead to seal failure due to aging, thus affecting the lamp tube's lifespan and safety. Moreover, most colloid materials contain chemical solvents, which do not meet increasingly stringent environmental protection requirements.

[0004] With rising environmental awareness, traditional glass lamp tubes and encapsulated UV LED lamp tubes are increasingly seen as products that do not conform to sustainable development. New materials and structural designs have become a focus of industry attention. For example, some manufacturers have attempted to replace glass with plastic and adopt modular designs to reduce the use of encapsulants, but these efforts have not yet achieved ideal results in terms of durability and tamper resistance. [Utility Model Content]

[0005] The main purpose of this utility model is to use the anti-tamper mechanism design to seal the ultraviolet light strip inside the lamp holder and lamp housing, avoiding the use of glue for fixing, thus making the whole more durable and environmentally friendly.

[0006] Another major objective of this invention is to simplify the structure and assembly of the anti-dismantling mechanism by utilizing the design of the installation guide groove, guide slope, anti-reverse wall and positioning block, thereby reducing material and assembly costs.

[0007] To achieve the above objectives, the structure of this utility model includes: a lamp holder, on which a plurality of ultraviolet lamp strips are provided, each ultraviolet lamp strip is provided with a plurality of light-emitting diodes, and each ultraviolet lamp strip is covered with a lamp housing attached to the lamp holder. At least one anti-disassembly mechanism is provided at the junction of the lamp holder and the lamp housing. The anti-disassembly mechanism includes a mounting guide groove, a guide ramp formed in the mounting guide groove, a backstop formed on one side of the guide ramp, and a positioning block that enters from the mounting guide groove and is restricted by the backstop on one side.

[0008] When the user uses this utility model as a UV lamp tube, the lamp housing and lamp holder are combined through an anti-tamper mechanism. First, the positioning block on the lamp housing is inserted into the mounting guide groove of the lamp holder. Then, it is rotated along the mounting guide groove and passed over the guide ramp. The positioning block can then be sealed in the mounting guide groove by the anti-reverse wall. The anti-tamper mechanism can non-removably seal the UV lamp strip with light-emitting diodes in the lamp holder and lamp housing, thus taking into account safety, durability and environmental protection.

[0009] By using the above technology, breakthroughs can be made in addressing the problems of low durability due to aging of the adhesive in ultraviolet light-emitting diode lamp tubes, high material and assembly costs, and the risk of toxic gas leakage, thus achieving the practical progress with the aforementioned advantages.

Detailed Implementation Methods

[0044] To achieve the above objectives and effects, the technical means and structure adopted by this utility model are described in detail below with reference to the preferred embodiment of this utility model, so as to facilitate a complete understanding.

[0045] Please see Figures 1 to 3 The figure shown is a perspective view of the first preferred embodiment of the present invention, illustrating the anti-tamper mechanism. The figure clearly shows that the present invention includes:

[0046] One lamp holder 1;

[0047] A plurality of ultraviolet lamp strips 2 are mounted on the lamp holder 1;

[0048] A plurality of light-emitting diodes 21 are disposed on each of the ultraviolet lamp strips 2;

[0049] A lamp housing 3 covers each of the ultraviolet lamp strips 2 and is attached to a lamp holder 1. Each ultraviolet lamp strip 2 has a first lamp plate 4 disposed on the lamp holder 1 and a second lamp plate 5 disposed inside the lamp housing 3 at both ends. The first lamp plate 4 has a plurality of through-holes 41 corresponding to the positions of each ultraviolet lamp strip 2, and the second lamp plate 5 has a plurality of slots 51 corresponding to the positions of each ultraviolet lamp strip 2.

[0050] At least one anti-tampering mechanism 6 is provided at the junction of the lamp holder 1 and the lamp housing 3, and includes a mounting guide groove 61, a guide ramp 62 formed in the mounting guide groove 61, a backstop wall 63 formed on one side of the guide ramp 62, and a positioning block 64 that enters from the mounting guide groove 61 and is restricted to one side of the backstop wall 63.

[0051] The lamp holder 1 is a housing for connecting or setting a power supply; the UV lamp strip 2 is exemplified by six lamp panels; the LEDs 21 are exemplified by seven LEDs on each UV lamp strip 2; the lamp housing 3 is exemplified by a hollow cylindrical plastic housing; the first lamp plate 4 is exemplified by a circular piece that abuts against the inner wall of the lamp holder 1; the perforation part 41 is exemplified by through holes arranged in a ring on the first lamp plate 4; the second lamp plate 5 is exemplified by a ring-shaped piece fixedly set inside the lamp housing 3; the slot part 51 is exemplified by grooves arranged in a ring on the second lamp plate 5; and the anti-tamper mechanism 6 is exemplified by a convex-concave locking mechanism. As an example, in this embodiment, the convex part is exemplified by the positioning block 64 disposed on the lamp housing 3, and the concave part is exemplified by the mounting guide groove 61 disposed on the lamp holder 1. The mounting guide groove 61 is exemplified by an L-shaped groove, thus including a mounting opening 611 for inserting the positioning block 64 and a guide groove portion 612 for restricting the movement direction of the positioning block 64. The guiding inclined surface 62 and the anti-reverse wall 63 together form a protrusion resembling a right-angled triangle, which is disposed within the guide groove portion 612, and its width is slightly equal to that of the guide groove portion 612 of the mounting guide groove 61. However, the corresponding forms of the above components are only examples of preferred embodiments. All forms with the same function are within the scope of this utility model and are not limited to the above examples.

[0052] The above explanation has provided an understanding of the structure of this technology. Based on the corresponding fit of this structure, the modular lamp tube structure with rotating buckles and anti-reverse tampering can be used to achieve advantages such as reducing costs, extending service life, ensuring safety in use, and meeting environmental protection requirements. A detailed explanation will follow below.

[0053] Please refer to the following at the same time. Figures 1 to 6 The figure shows a perspective view to a schematic diagram of the operation of the first preferred embodiment of the present invention (III). When the above components are assembled, it can be clearly seen from the figure that when the user uses the present invention as an ultraviolet lamp tube, it is combined with the lamp housing 3 and the lamp holder 1 through the anti-tamper mechanism 6. Specifically, during assembly, the ultraviolet lamp strips 2 are first housed in the lamp housing 3, and one end of the ultraviolet lamp strip 2 is inserted and fixed in the slot 51 of the second lamp plate 5. Then, the other end is inserted into the through hole 41 of the first lamp plate 4. At this time, the ultraviolet lamp strips 2 are arranged in a ring at equal intervals between the first lamp plate 4 and the second lamp plate 5. The space around the center is the heat dissipation space 22 of the light-emitting diode 21. The second lamp plate 5 is also ring-shaped, so the heat can be discharged from the heat dissipation space 22 through the hollowed-out part in the center of the second lamp plate 5 and through the heat dissipation hole at the end of the lamp housing 3, thus having a good heat dissipation effect.

[0054] Next, the lamp holder 1 and the lamp housing 3 are assembled. The positioning block 64 on the lamp housing 3 is inserted into the mounting opening 611 of the mounting guide groove 61. At this time, the first lamp plate 4 naturally abuts against and is positioned on the inclined wall surface of the lamp holder 1 (e.g., Figure 1 As shown), and in conjunction with the second lamp plate 5 fixed on the lamp housing 3, the ultraviolet light strip 2 can be stably fixed in the lamp housing 3 and the lamp holder 1. Then, rotate the lamp housing 3 or the lamp holder 1 to make the positioning block 64 move circumferentially along the guide groove 612 of the mounting guide groove 61 (the axial, radial, and circumferential directions mentioned below are all based on this rotation direction). After crossing the guide slope 62, the design of the anti-reverse wall 63 prevents the positioning block 64 from reversing out of the mounting guide groove 61, thus sealing the positioning block 64 in the mounting guide groove 61. This completes the assembly of the lamp housing 3 and the lamp holder 1. The anti-disassembly mechanism 6 secures the ultraviolet light strip 2 with the light-emitting diode 21 in the lamp holder 1 and the lamp housing 3 in a non-removable manner, preventing the user from accidentally disassembling it and causing danger. By utilizing a simple rotating buckle design to replace the traditional glue fixation, the assembly difficulty can be simplified while maintaining the existing safety. At the same time, the problems of easy aging and short life of traditional UV lamp glue are eliminated. The modular lamp housing 3 and lamp holder 1 are used for mechanized fixation, which improves the overall durability. The production cost can also be reduced during mass production. Furthermore, by eliminating the use of glue and mercury, this utility model has high environmental benefits.

[0055] Please refer to the following at the same time. Figure 7The diagram shows a second preferred embodiment of the present invention with an elastic fixing mechanism. As can be clearly seen from the diagram, the main difference between this embodiment and the previous embodiment is the optimized fixing method of the UV lamp strips 2. The resulting structure includes: the second lamp plate 5 has a plurality of elastic members 52 on the side opposite to each UV lamp strip 2, which push against the inner wall of the lamp housing 3 to compress each UV lamp strip 2 in the opposite direction, and each elastic member 52 has an arc-shaped portion 521 at its end. In this embodiment, the second lamp plate 5 is simply placed inside the lamp housing 3 without being fixed, as an example. The elastic member 52 is a long strip-shaped sheet, with one end connected to the slot portion 51 on the side opposite to the UV lamp strip 2, and the other end movably abutting against the end wall of the lamp housing 3. The arc-shaped portion 521 is formed as a hemispherical protrusion at the end of the elastic member 52.

[0056] Thus, the insertion of the UV lamp strip 2 into the lamp housing 3 is not only temporarily fixed by the first lamp plate 4 and the second lamp plate 5, but also provides a certain buffering effect due to the presence of the elastic element 52, which increases the safety of the insertion action and avoids forceful collisions caused by improper operation, or even damage to the UV lamp strip 2 or the light-emitting diode. Furthermore, when the lamp housing 3 is assembled with the lamp holder 1, the reaction force generated by the elastic element 52 pushing against the inner wall of the lamp housing 3 can be used to squeeze the second lamp plate 5 and the UV lamp strip 2 towards the lamp holder 1, so that the first lamp plate 4 can more firmly and tightly press against the inner wall of the lamp holder 1, preventing the UV lamp strip 2 from shaking or colliding inside the lamp housing 3.

[0057] In addition, when the lamp housing 3 and the lamp holder 1 are rotated and fixed, the rotation of the lamp holder 1 may simultaneously drive the first lamp plate 4 to rotate. Although the second lamp plate 5 is not fixed, the friction of the side edge against the lamp housing 3 may cause a difference in the rotation amplitude of the first lamp plate 4 and the second lamp plate 5, which may lead to the problem of the ultraviolet light strip 2 being twisted. Therefore, the elastic member 52 of this utility model uses the design of the arc part 521 to reduce the contact area between the elastic member 52 and the lamp housing 3, reduce the friction generated during rotation, and allow the first lamp plate 4 and the second lamp plate 5 to rotate more synchronously, making the assembly action easier and smoother.

[0058] Alternatively, a plurality of notches 42 may be provided on the side edge of the first lamp plate 4, and a plurality of positioning parts 31 corresponding to and engaging with each of the notches 42 may be provided on the inner side of the lamp housing 3. In this way, when the positioning parts 31 engage with the notches 42, the first lamp plate 4 will be locked and prevent relative rotation with the lamp housing 3, thereby eliminating the difference in rotation amplitude between the first lamp plate 4 and the second lamp plate 5. Even if the lamp holder 1 rotates, friction may act on the first lamp plate 4, but this friction cannot be greater than the positioning effect of the positioning parts 31 and the notches 42, thereby ensuring that the ultraviolet light strip 2 and the light-emitting diode can be installed without damage.

[0059] Please refer to the following at the same time. Figure 8 and Figure 9The figure shows a structural schematic diagram and a rotation limit schematic diagram of the third preferred embodiment of the present invention. As can be clearly seen from the figure, the main difference between this embodiment and the above embodiments is that the rotation range is limited for the rotation fixing action to avoid structural damage caused by improper operation. The structure includes: at least one auxiliary limiting part 11 on the inner side wall of the lamp holder 1 to limit the rotation range of the lamp housing 3, and at least one abutting part 32 corresponding to the auxiliary limiting part 11 at the opening end of the lamp housing 3. The auxiliary limiting part 11 is a protruding structure on the inner sidewall of the lamp holder 1. In this embodiment, a vertically arranged sheet-like shape is used as an example. The supporting part 32 is a protruding structure at the opening end of the lamp housing 3. In this embodiment, an arc-shaped sheet-like shape extending from the opening end of the lamp housing 3 is used as an example. The protrusion direction of the auxiliary limiting part 11 is radial, and the protrusion direction of the supporting part 32 is axial. In this way, the two protruding structures, the auxiliary limiting part 11 and the supporting part 32, can abut against each other, limiting the rotation range of the lamp housing 3. In principle, as long as the supporting part 32 is arranged equidistantly on one side of the auxiliary limiting part 11 according to the allowable circumferential movement distance of the positioning block 64 in the mounting guide groove 61, the rotation range of the lamp housing 3 can be limited with only one auxiliary limiting part 11 and the supporting part 32. In actual operation, since the lamp holder 1 and the lamp housing 3 rotate relative to each other or in opposite directions, when the positioning block 64 rotates clockwise, the auxiliary limiting part 11 will rotate counterclockwise relative to it.

[0060] When there are multiple auxiliary limiting parts 11, a support part 111 is defined on its upper surface to support the first lamp plate 4. The support part 111 refers to the plane formed by the thickness of the auxiliary limiting parts 11. Therefore, the support direction is the axial direction from the lamp holder 1 to the lamp housing 3. In other words, when the first lamp plate 4 is set at the end of the ultraviolet lamp strip 2, in addition to the support of the side edge of the lamp housing 3 and the support of the step 23 of the ultraviolet lamp strip 2, since the support of both is in the axial direction from the lamp housing 3 to the lamp holder 1, the support in the axial direction from the lamp holder 1 to the lamp housing 3 can only rely on the inclined inner side wall of the lamp holder 1. However, in this embodiment, the support part 111 can be used for multi-point support, which not only avoids the first lamp plate 4 from compressing the housing space of the wires in the lamp holder 1, but also more stably fixes the first lamp plate 4.

[0061] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Therefore, any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included in the patent scope of the present utility model and are hereby stated.
