Description

Technical Field

[0001] This utility model relates to the field of profile technology, specifically to a lamp tube profile for indoor lighting. Background Technology

[0002] Against the backdrop of a renewed global energy shortage, the development, research, and production of LED products have become a very promising industry. When using LED products, they are often installed and fixed with lamp tube profiles. For example, patent document CN201721752236.6 discloses a novel lamp tube profile for indoor lighting. The cross-section of the profile body includes a top plate and two side plates. The side plates are connected to the lower left and right ends of the top plate, and the three together define an assembly cavity, the lower part of which is open. Two first hooks are formed on the top plate, creating an insertion space. An assembly groove is recessed in the middle of the upper surface of the top plate, and a flat positioning groove is recessed on the lower surface of the top plate corresponding to the assembly groove. The two side walls of the assembly groove protrude with locking points facing the assembly cavity, and the two locking points are located above the flat positioning groove. Two screw positioning parts are also provided on the lower surface of the top plate, spaced apart from the assembly groove. The bottom of each side plate is integrally bent to form a second hook, with the hook-shaped parts of the two second hooks facing each other. The assembly groove is used to assemble lighting components, and the flat positioning groove is used to assemble LED light strips.

[0003] The technical solutions disclosed in the aforementioned patent documents demonstrate the scenario of using lamp tube profiles in conjunction with LED products; however, their practical application still has limitations, as follows:

[0004] First, the structure is relatively complex. Although it has many functions, it takes a long time to produce. For example, in the technical solution disclosed in the above patent documents, not only do the top plate need to be recessed, but hooks also need to be set in the recessed area. The overall process is complicated and not conducive to production.

[0005] Second, in the technical solutions disclosed in the above-mentioned patent documents, components such as light sources, connecting wires, and connecting terminals are installed in the assembly cavity. This results in the assembly cavity having to accommodate a large number of components. It is easy for the light source (referring to LED light strips, light source PCBs, etc.) to squeeze and occupy the space where the connecting wires are located after installation. This causes the connecting wires to be squeezed in a certain area. Once the light source generates a lot of heat, it is easy for the heat in the assembly cavity to accumulate, affecting the service life of the lamp tube (for example, accelerating the aging speed of the connecting wires or terminal leads).

[0006] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0007] This utility model provides a lamp tube profile for indoor lighting, aiming to solve the technical problems mentioned in the background art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a lamp tube profile for indoor lighting, comprising a profile body;

[0009] Viewed from a cross-sectional perspective, the profile body includes a first longitudinal plate, a second longitudinal plate, a partition plate, a locking cover groove plate, and a connecting plate;

[0010] In the same plane, the first vertical plate and the second vertical plate are symmetrically arranged and spaced apart. In the area between the first vertical plate and the second vertical plate, the partition plate, the locking cover groove plate and the connecting plate are connected sequentially along the horizontal direction.

[0011] One end of the partition plate is integrally connected to the first longitudinal plate, and the other end of the partition plate is integrally connected to the lock cover groove plate. The lock cover groove plate is bent upward and extends to form a protrusion. One end of the connecting plate is integrally connected to the second longitudinal plate, and the other end of the connecting plate is integrally connected to the side of the protrusion away from the partition plate.

[0012] Above the area between the first longitudinal plate and the second longitudinal plate, the first longitudinal plate, the partition plate, and the protrusion define a module installation space;

[0013] Below the area between the first vertical plate and the second vertical plate, the first vertical plate, the partition plate, the locking cover groove plate, the connecting plate and the second vertical plate define a light source mounting space;

[0014] The profile body also includes a pair of light source fixing hooks. The pair of light source fixing hooks are located below the partition plate and are symmetrically arranged with respect to the axis of symmetry of the first longitudinal plate and the second longitudinal plate. The lower ends of the pair of light source fixing hooks are bent and each forms a hook claw portion. The two hook claw portions are arranged opposite each other below the pair of light source fixing hooks.

[0015] Two protruding fins are provided on the lower inner side of the light source installation space. The two protruding fins are symmetrically arranged with reference to the axis of symmetry of the first longitudinal plate and the second longitudinal plate. A lower step is provided at the lower end of both the first longitudinal plate and the second longitudinal plate. The two lower steps are symmetrically arranged with reference to the axis of symmetry of the first longitudinal plate and the second longitudinal plate.

[0016] A reflective groove is defined between the lower step, the inner wall of the light source mounting space, and the protruding fin.

[0017] The module installation space has two auxiliary protrusions on the upper inner side. The two auxiliary protrusions are symmetrically arranged with respect to the axis of symmetry of the first longitudinal plate and the second longitudinal plate. The upper ends of the first longitudinal plate and the second longitudinal plate are each provided with an upper step. The two upper steps are symmetrically arranged with respect to the axis of symmetry of the first longitudinal plate and the second longitudinal plate.

[0018] A steel plate positioning groove is defined between the upper step, the inner wall of the module installation space, and the auxiliary protrusion.

[0019] The relevant content in the above plan is explained as follows:

[0020] In the above scheme, the module mounting space is designed to install drivers, connecting wires, and connecting terminals; while the light source mounting space is designed to install fixed light source PCBs.

[0021] In the above scheme, the light source refers to the light source PCB. In order to make the light irradiation direction directly below the light source installation space, a reflector and a PCB light-emitting plate will also be installed in the light source installation space.

[0022] In the above solution, the locking cover groove plate and the protrusion are integrally formed, and the locking cover groove plate fixes the end cover through the protrusion. The structure of the end cover can be referred to Figure 9 .

[0023] In the above scheme, the functions of the reflector groove are: 1. to hold the reflector in place; 2. to install the PC light-emitting plate.

[0024] In the above scheme, the function of the steel plate positioning groove is to fix and install the steel plate, and the steel plate can be installed on the wall by screws and other components.

[0025] In a further technical solution, the lamp tube profile also includes a matching profile for fixing the light source;

[0026] The matching profile includes a first horizontal plate and a second horizontal plate;

[0027] Along the direction of upward extension of the lock cover groove plate, the second horizontal plate, the first horizontal plate and the partition plate are arranged parallel and spaced apart. The second horizontal plate is integrally connected to the first horizontal plate. A pair of connecting hooks are provided on the side of the first horizontal plate away from the second horizontal plate. The pair of connecting hooks are symmetrically arranged with respect to the axis of symmetry of the first vertical plate and the second vertical plate.

[0028] Both ends of the second horizontal plate are bent toward the side away from the first horizontal plate to form a fixing part, and the light source is configured to be fixed between the two fixing parts.

[0029] Different types of light sources can be selected (such as light source PCBs, LED light strips, etc.). When a light source PCB is selected, a reflector and a PC light-emitting plate are often designed to ensure that the light is more concentrated. In order to ensure that the above components can be fully fixed, the light source PCB is fixed between the two fixing parts by means of the above design. Then, the reflector is clipped on both sides of the light source PCB to form a figure-eight shape. At the same time, the PC light-emitting plate is fixed in the groove of the reflector, thus completing the fixation of the light source PCB.

[0030] A further technical solution is that the protrusion has a U-shaped cross-section. This design allows for quick and easy fixing of the end cap fasteners (screws) without the need to drill holes in the protrusion.

[0031] In a further technical solution, the cross-section of the protruding fin is approximately T-shaped;

[0032] Within the space where the light source is installed;

[0033] A first steel sheet fixing groove is defined between one of the protruding fins, the first longitudinal plate, and the partition plate;

[0034] A second steel sheet fixing groove is defined between the other protruding fin, the second longitudinal plate, the bottom of the protrusion, and the connecting plate.

[0035] In some special cases, it is necessary to fix two profile bodies together. In this case, a fixing steel plate can be placed in the first steel plate fixing groove and the second steel plate fixing groove respectively (the fixing steel plate is located between the two profile bodies). Then, screws are inserted into the light source installation space and screwed to the fixing steel plate to achieve the connection of the two profile bodies.

[0036] The cross-section of the raised fin is approximately T-shaped; for details, please refer to [reference needed]. Figure 1 Because the T-shaped head of the protruding fin is bent, the space of the reflector groove is larger, which facilitates the installation of the reflector.

[0037] A further technical solution is that a guide head is integrally connected to the second horizontal plate between the two connecting hooks;

[0038] When the matching profile is used to fix the light source, the pair of connecting hooks are configured to be positioned and connected to the claw portions on the two light source fixing hooks respectively, and the guide head is configured to be inserted between the two light source fixing hooks.

[0039] In a further technical solution, the guide head is an arc plate, and the end of the arc plate is integrally connected to the first horizontal plate;

[0040] The arc plate and the first horizontal plate are provided with a through hole, and the arc plate has a notch.

[0041] To improve the stability of the light source PCB during fixing, the light source PCB is first fixed to the matching profile, and then the matching profile is positioned by two connecting hooks. After that, screws are inserted. As the screws pass through the through holes, the notch expands, allowing the arc plate to abut against the two connecting hooks. Therefore, the stability of the matching profile after connection is high.

[0047] The working principle and advantages of this utility model are as follows:

[0048] In this invention, the module mounting space is designed to install the driver, connecting wires, and connecting terminals; while the light source mounting space is designed to install and fix the light source PCB. In this application, the light source refers to the light source PCB. In order to ensure that the light irradiation direction is directly below the light source mounting space, a reflector and a PC light-emitting plate are also installed in the light source mounting space. This design allows the light source PCB and connecting wires to be placed in different chambers, preventing the connecting wires from being occupied by the light source PCB, and thus avoiding the problem of accelerated aging of connecting wires mentioned in the prior art.

[0049] In this utility model, the module installation space is defined by the first vertical plate, the partition plate, and the protrusion; the light source installation space is defined by the first vertical plate, the partition plate, the locking cover groove plate, the connecting plate, and the second vertical plate. From a structural perspective, it makes full use of each component, and each component exists independently. Unlike the existing technology where the top plate not only needs to have a recess but also needs to have a hook at the recess, the profile provided by this utility model has low production difficulty and fewer processes.

[0060] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0061] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0062] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0063] See appendix Figures 1-9 As shown, a lamp tube profile for indoor lighting includes a profile body 1;

[0064] Viewed from a cross-sectional perspective, the profile body 1 includes a first longitudinal plate 2, a second longitudinal plate 3, a partition plate 4, a locking cover groove plate 5, and a connecting plate 6;

[0065] In the same plane, the first vertical plate 2 and the second vertical plate 3 are symmetrically arranged and spaced apart. In the area between the first vertical plate 2 and the second vertical plate 3, the partition plate 4, the locking cover groove plate 5 and the connecting plate 6 are connected sequentially along the horizontal direction.

[0066] One end of the partition plate 4 is integrally connected to the first longitudinal plate 2, and the other end of the partition plate 4 is integrally connected to the lock cover groove plate 5. The lock cover groove plate 5 is bent upward and extends to form a protrusion 7. One end of the connecting plate 6 is integrally connected to the second longitudinal plate 3, and the other end of the connecting plate 6 is integrally connected to the side of the protrusion 7 away from the partition plate 4.

[0067] Above the area between the first vertical plate 2 and the second vertical plate 3, the first vertical plate 2, the partition plate 4 and the protrusion 7 define a module installation space 8;

[0068] Below the area between the first vertical plate 2 and the second vertical plate 3, the first vertical plate 2, the partition plate 4, the locking cover groove plate 5, the connecting plate 6 and the second vertical plate 3 define a light source mounting space 9.

[0069] The profile body 1 also includes a pair of light source fixing hooks 10. The pair of light source fixing hooks 10 are arranged below the partition plate 4, and the pair of light source fixing hooks 10 are symmetrically arranged with reference to the axis of symmetry of the first longitudinal plate 2 and the second longitudinal plate 3. The lower ends of the pair of light source fixing hooks 10 are bent and each forms a hook claw part 11. The two hook claw parts 11 are arranged opposite to each other below the pair of light source fixing hooks 10.

[0070] Two protruding fins 12 are provided on the lower inner side of the light source mounting space 9. The two protruding fins 12 are symmetrically arranged with reference to the axis of symmetry of the first longitudinal plate 2 and the second longitudinal plate 3. A lower step 13 is provided at the lower end of both the first longitudinal plate 2 and the second longitudinal plate 3. The two lower steps 13 are symmetrically arranged with reference to the axis of symmetry of the first longitudinal plate 2 and the second longitudinal plate 3.

[0071] A reflective groove is defined between the lower step 13, the inner wall of the light source mounting space 9, and the protruding fin 12.

[0072] The module installation space 8 has two auxiliary protrusions 14 on its upper inner side. The two auxiliary protrusions 14 are symmetrically arranged with respect to the axis of symmetry of the first vertical plate 2 and the second vertical plate 3. The upper ends of the first vertical plate 2 and the second vertical plate 3 are each provided with an upper step 15. The two upper steps 15 are symmetrically arranged with respect to the axis of symmetry of the first vertical plate 2 and the second vertical plate 3.

[0073] A steel plate positioning groove is defined between the upper step 15, the inner wall of the module installation space 8, and the auxiliary protrusion 14.

[0074] In this invention, the module mounting space 8 is designed to install the driver, connecting wires, and connecting terminals; while the light source mounting space 9 is designed to install and fix the light source PCB. In this application, the light source refers to the light source PCB. In order to ensure that the light irradiation direction is directly below the light source mounting space 9, a reflector and a PC light-emitting plate are also installed in the light source mounting space 9. This design allows the light source PCB and connecting wires to be placed in different chambers, preventing the connecting wires from being occupied by the light source PCB, and thus avoiding the problem of accelerated aging of connecting wires mentioned in the prior art.

[0075] In this utility model, the module installation space 8 is defined by the first longitudinal plate 2, the partition plate 4, and the protrusion 7; the light source installation space 9 is defined by the first longitudinal plate 2, the partition plate 4, the locking cover groove plate 5, the connecting plate 6, and the second longitudinal plate 3. From the structural composition, each component is fully utilized, and each component exists independently. This is different from the technical solution in the prior art where not only a recess needs to be set on the top plate, but also a hook needs to be set in the recess. The profile provided by this utility model has low production difficulty and fewer processes.

[0076] In this utility model, the locking cover groove plate 5 and the protrusion 7 are integrally formed, and the locking cover groove plate 5 fixes the end cover through the protrusion 7. The structure of the end cover can be referred to Figure 9 .

[0077] In this utility model, the reflector groove serves two purposes: 1. to hold the reflector in place; 2. to install the PC light-emitting plate.

[0078] In this invention, the steel plate positioning groove is used to fix and install the steel plate, which can be installed on the wall by screws or other components.

[0079] In some specific implementations, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The lamp tube profile also includes a matching profile 16 for fixing the light source;

[0080] The matching profile 16 includes a first horizontal plate 17 and a second horizontal plate 18;

[0081] Along the direction of upward extension of the lock cover groove plate 5, the second horizontal plate 18, the first horizontal plate 17 and the partition plate 4 are arranged parallel and spaced apart. The second horizontal plate 18 is integrally connected with the first horizontal plate 17. A pair of connecting hooks 19 are provided on the side of the first horizontal plate 17 away from the second horizontal plate 18. The pair of connecting hooks 19 are symmetrically arranged with reference to the axis of symmetry of the first vertical plate 2 and the second vertical plate 3.

[0082] Both ends of the second horizontal plate 18 are bent toward the side away from the first horizontal plate 17 to form a fixing part 20, and the light source is configured to be fixed between the two fixing parts 20.

[0083] Different types of light sources can be selected (such as light source PCBs, LED light strips, etc.). When a light source PCB is selected, a reflector and a PC light-emitting plate are often designed to ensure that the light is more concentrated. In order to ensure that the above components can be fully fixed, the light source PCB is fixed between the two fixing parts 20 by means of the above design. Then, the reflector is clipped on both sides of the light source PCB to form a figure-eight shape. At the same time, the PC light-emitting plate is fixed in the groove of the reflector, thus completing the fixation of the light source PCB.

[0084] In some specific implementations, such as Figure 1 as well as Figures 3-8 As shown, the protrusion 7 has a U-shaped cross-section.

[0085] The above design allows the fasteners (screws) for fixing the end cap to be quickly secured without drilling holes in the protrusion 7.

[0086] In some specific implementations, such as Figure 1 as well as Figures 3-8 As shown, the cross-section of the protruding fin 12 is approximately T-shaped;

[0087] Within the installation space 9 of the light source;

[0088] A first steel sheet fixing groove is defined between one of the protruding fins 12, the first longitudinal plate 2, and the partition plate 4;

[0089] A second steel sheet fixing groove is defined between the other protruding fin 12, the second longitudinal plate 3, the bottom of the protrusion 7, and the connecting plate 6.

[0090] In some special cases, such as when lights need to be installed along the length of the wall at the top, it is necessary to fix the two profile bodies 1 together. Therefore, a fixing steel plate can be placed in the first steel plate fixing groove and the second steel plate fixing groove respectively (the fixing steel plate is located between the two profile bodies 1, specifically divided into two parts with the abutment surface between the two profile bodies 1 as the dividing line, and each part corresponds to the two profile bodies 1 respectively). Then, screws are inserted into the light source installation space 9 and screwed to the fixing steel plate (that is, a screw is inserted into each part of the fixing steel plate), thus connecting the two profile bodies 1.

[0091] In some specific implementations, such as Figure 1 as well as Figures 3-8 As shown, a guide head 21 integrally connected to the second horizontal plate 18 is provided between the two connecting hooks 19;

[0092] When the matching profile 16 fixes the light source, the pair of connecting hooks 19 are configured to be positioned and connected one-to-one with the claw portions 11 on the two light source fixing hooks 10, and the guide head 21 is configured to be inserted between the two light source fixing hooks 10.

[0093] In some specific implementations, such as Figure 1 as well as Figures 3-8 As shown, the guide head 21 is an arc plate, and the end of the arc plate is integrally connected to the first horizontal plate 17.

[0094] The arc plate and the first horizontal plate 17 are provided with a through hole 22, and the arc plate has a notch 23.

[0095] To improve the stability of the light source during fixing, the light source is first fixed on the matching profile 16, and then the matching profile 16 is positioned by two connecting hooks 19. Then, screws are inserted. After the screws pass through the through hole 22, the notch 23 will expand, so that the arc plate abuts against the two connecting hooks 19. Therefore, the stability of the matching profile 16 after connection is high.

[0096] Working principle:

[0097] When installing the light source PCB:

[0098] The matching profile 16 is directly guided into the light source installation space 9. Then, the two connecting hooks 19 are guided to match and connect with the claw portions 11 on the two light source fixing hooks 10 respectively (the claw portions 11 on the light source fixing hooks 10 are preferably formed after being bent at ninety degrees, so that the stability is higher when the connecting hooks 19 and the claw portions 11 are positioned and connected). After the matching connection is completed, the guide head 21 is inserted between the two light source fixing hooks 10.

[0099] Subsequently, a light source PCB is placed between the two fixing parts 20. Then, a guide screw is passed through the light source PCB to fix it. The guide screw passes through the through hole 22 and the notch 23 in sequence. When the screw enters the notch 23, it will expand the notch 23, so that the arc plate abuts against the two connecting hooks 19. Therefore, the stability of the matching profile 16 after connection is high (that is, not only is the fixation of the light source PCB completed, but also the fixation of the matching profile 16 is completed).

[0100] Then, a reflector and a PC light-emitting plate (a light guide plate made of PC material) are added. The reflector is L-shaped, with one end having a hook that can be positioned in the first or second steel plate fixing slot, and the other end inserted between the light source PCB and the fixing part 20. Specifically, two reflectors are provided, as shown in the reference. Figure 5 and Figure 6 .

[0101] Two reflectors are placed on either side of the light source PCB, and the PC light-emitting plate is placed below the two reflectors.

[0102] After the light source PCB is fixed, the connecting wires and other components need to be fixed. They can be placed directly in the module installation space 8. Then, the steel sheet is fixed in the steel sheet positioning groove. The steel sheet can be installed on the wall with screws and other components.

[0103] Finally, the end cap is secured by the protrusion 7.

[0104] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
