Description
Technical Field
[0001] This utility model relates to the field of lighting technology, specifically to a light source module fixing structure and a ceiling light using the light source module fixing structure. Background Technology
[0002] As a common indoor lighting device, the installation stability of the light source module of a ceiling light directly affects the lighting effect and service life. Existing ceiling light light source module fixing structures include a chassis, a light source module, and bolts. The chassis is a hardware component with connection holes. The light source module includes a light source plate and a pressure plate. The light source plate has a first through hole, and the pressure plate has a second through hole. When assembling the chassis and light source module, the light source plate is first placed on the corresponding installation area on the chassis, aligning the first through hole with the connection hole. Then, the pressure plate is placed on the light source plate, aligning the second through hole with the first through hole. Finally, the bolts are passed through the second and first through holes and connected to the connection hole to fix the light source module to the chassis. However, the existing light source module fixing structure has the following shortcomings: First, bolts are needed to connect the chassis and the light source module, which increases material costs. Secondly, ceiling lights usually require multiple light source modules to ensure lighting brightness and uniformity. However, when connecting multiple light source modules to the chassis, they need to be installed one by one. That is, one light source module must be bolted to the chassis before the next light source module can be assembled to the chassis. This results in multiple light source modules not being able to be installed and fixed at the same time, which prolongs the overall assembly time and reduces assembly efficiency. Third, since the chassis is made of metal and is relatively thin, stripping can easily occur during the connection of the connecting holes and bolts, thus increasing the defect rate. Utility Model Content
[0003] The primary objective of this invention is to provide a light source module fixing structure that has low production costs, improves production efficiency, and has a low defect rate.
[0004] The second objective of this invention is to provide a ceiling light that employs the aforementioned light source module fixing structure.
[0005] To achieve the first objective of this utility model, it provides a light source module fixing structure, including a chassis and a light source module. The light source module includes a light source plate and a pressure plate. The chassis has a mounting boss, and the mounting boss has a placement area. The placement area has a positioning protrusion group and a tongue. The light source plate includes a light-emitting component and a plate body. The light-emitting component is mounted on the plate body, and the plate body has a positioning groove group and a first through groove that penetrate through it. The pressure plate includes a pressing part and a wiring part. The pressing part has a receiving groove, and the bottom wall of the receiving groove has a clearance position and a second through groove that penetrate through it. The wiring part has a clearance cavity and a wire passage groove, and the wire passage groove communicates with the clearance cavity. The light source plate is placed in the placement area, the positioning groove group and the positioning protrusion group are engaged and connected, the plate body is located in the receiving groove and the clearance cavity, the light-emitting component passes through the clearance position, and the tongue passes through the first through groove and the second through groove and then bends and fits against the top surface of the pressing part.
[0006] As can be seen from the above, the cooperation between the tongue and the first and second through slots serves two purposes. First, the tongue acts as a positioning pin, preventing the light source board and pressure plate from detaching from the placement area. This also provides feasibility for the subsequent synchronous fixing of the multi-light source module and the chassis. Second, with the cooperation of the tongue, all the tongues on the chassis of the processing equipment can be bent simultaneously to achieve simultaneous fixing of the multi-light source module and the chassis, thereby significantly improving assembly efficiency. In addition, since the tongue is integrally formed by the chassis through a stamping process, compared with the traditional light source module fixing structure, this light source module fixing structure does not require additional bolts to fix the light source module and the chassis, saving the number of parts required for assembly, thereby significantly reducing production costs and also significantly reducing the defect rate during the assembly process.
[0007] A further solution is that the positioning protrusion group includes two positioning protrusions, which are distributed at both ends of the plate in the length direction of the plate; the positioning groove group includes two positioning grooves, which are located at both ends of the plate in the length direction, and one positioning groove is engaged with one positioning protrusion.
[0008] As can be seen from the above, the design can ensure the reliability of the positioning and limiting of the light source board, and can simplify the structure of the chassis and the light source board to the greatest extent, reduce production costs, and ensure the structural strength of the light source board.
[0009] A further improvement is that the placement area has two tongues located between two positioning protrusions; the plate has two first through slots, each corresponding to one of the two tongues; and the pressing part has two second through slots, each corresponding to one of the two tongues.
[0010] As can be seen from the above, the design can ensure the reliability of fixing the light source module to the chassis, and can simplify the structure of the chassis, light source board and pressure plate to the greatest extent, reduce production costs, and ensure the structural strength of the chassis, light source board and pressure plate.
[0011] A further solution is to bend the two tongues in opposite directions.
[0012] As can be seen from the above, this design enables the pressure plate to be subjected to uniform force and ensures the stability and firmness of the fixed connection between the light source module and the chassis.
[0013] A further improvement is that the pressure plate includes two wiring sections, which are located at both ends of the pressing section; a positioning protrusion is located in the cavity of one of the wiring sections.
[0014] As can be seen from the above, the two wiring sections on the pressure plate make it easier to connect adjacent pressure plates when multiple pressure plates are connected end to end. At the same time, each positioning protrusion can be located outside the pressing part of the pressure plate and housed inside the wiring section. This prevents the pressure plate from warping when the height of the positioning protrusion is higher than the body of the light source board, and also avoids gaps between the pressure plate and the mounting boss, thus better fixing and protecting the light source board.
[0015] A further proposed solution involves three to eight placement areas; three to eight sets of light source modules, with each set of light source modules corresponding to one of the placement areas; and the pressure plates of the multiple light source modules connected end to end to form a polygon, with the cable trays of the two wiring sections of two adjacent pressure plates forming a cable passage.
[0016] As can be seen from the above, this design allows the number of light source modules to be flexibly adjusted according to the lighting power and lighting requirements of the ceiling light, thereby improving the practicality and applicability of the ceiling light.
[0017] A further proposed solution is that the chassis has a receiving cavity, and the mounting boss is recessed into the receiving cavity from the bottom of the receiving cavity. The cavity wall has two or more connecting pins, which are distributed along the circumference of the chassis. The mounting boss has a two-tiered stepped structure and is frame-shaped.
[0018] As can be seen from the above, this design makes it easier to mold the chassis in one piece, and with the help of the mounting boss, it can ensure the structural strength of the bottom surface of the cavity, so that the bottom of the cavity can support heavy objects such as power modules. At the same time, it can also enable the mounting boss to stably support the light source module and reliably fix the light source module on itself.
[0019] A further proposed solution is that the bottom of the receiving cavity is provided with multiple slots and two or more reserved blind holes. The multiple slots are located on the outer periphery of the mounting boss and distributed circumferentially, while the two or more reserved blind holes are located on the inner ring of the mounting boss. The bottom of the reserved blind holes is provided with a conical part that protrudes away from the opening of the receiving cavity.
[0020] As can be seen from the above, the design provides different options for the connection between the chassis and the external wall, so that users can choose the most suitable installation solution according to the actual installation environment, thereby improving the chassis's practical adaptability and installation flexibility.
[0021] To achieve the second objective of this utility model, this utility model provides a ceiling light, including a lampshade, which further includes the aforementioned light source module fixing structure. The lampshade is detachably connected to the chassis and covers the light source module.
[0022] As can be seen from the above, by adopting the aforementioned light source module fixing structure, ceiling lights can effectively reduce production costs, improve production efficiency, and reduce the defect rate during the production process.
[0023] A further option is that the ceiling light also includes a power module and wiring terminals, with the power module electrically connected between the light source board and the wiring terminals; both the power module and the wiring terminals are mounted on the chassis, and both are located within the space enclosed by the chassis and the lampshade.
[0024] As can be seen from the above, this design can improve the integration of the ceiling light, while also avoiding the impact on safety and aesthetics caused by placing the power module, wiring terminals, etc. outside the ceiling light. Attached Figure Description

[0026] Figure 2 This is an exploded view of the first omitted component of the ceiling light embodiment of this utility model.
[0027] Figure 3 yes Figure 1 Enlarged view of point A in the middle.
[0028] Figure 4 This is a structural diagram of the second omitted component of the ceiling light embodiment of this utility model.
[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation
[0030] Ceiling light example Reference Figure 1The ceiling light 100 includes a lampshade, a light source module fixing structure 101, a power module 102, and a wiring terminal 103. The light source module fixing structure 101 includes a chassis 1 and a light source module 2.
[0031] Combination Figure 2 The chassis 1 has a receiving cavity 11 and a mounting boss 12. The mounting boss 12 is recessed into the receiving cavity 11 from the bottom. This design facilitates the integral molding of the chassis 1 and enhances the structural strength of the bottom surface of the receiving cavity 11, allowing the bottom of the receiving cavity 11 to support heavy objects such as the power module 102. Preferably, the mounting boss 12 has a two-step structure. This design enhances the structural strength of the mounting boss 12, enabling it to stably support the light source module 2 and reliably fix the light source module 2 to itself. It also makes the molding of the chassis 1 and the mounting boss 12 more convenient and easier. Furthermore, the mounting boss 12 is frame-shaped.
[0032] The bottom of the receiving cavity 11 is provided with slots 111 and reserved blind holes 112. There are multiple slots 111, and the multiple slots 111 are evenly distributed along the circumference of the chassis 1. In this embodiment, there are three slots 111 to ensure that the ceiling light 100 can be firmly installed on the external wall. The slots 111 penetrate through the bottom of the receiving cavity 11 and are distributed outside the mounting boss 12.
[0033] The number of reserved blind holes 112 is two or more, and the reserved blind holes 112 are located on the inner ring of the mounting boss 12. In this embodiment, the number of reserved blind holes 112 is preferably two. The bottom of the reserved blind hole 112 is provided with a conical part 1121, and the conical part 1121 protrudes away from the opening of the receiving cavity 11. The design of the conical part 1121 is to guide and position the screws through the reserved blind holes 112 when the user installs the chassis 1 on the external wall through the reserved blind holes 112, so as to ensure the position of the screws in each reserved blind hole 112, and ensure the positional accuracy between each opening. This allows the chassis 1 to be smoothly installed on the external wall and is not easily deformed after installation, preventing the light source module 2, power module 102, etc. installed on the chassis 1 from being squeezed. At the same time, it also ensures the reliability and installation positional accuracy of the chassis 1.
[0034] By simultaneously setting slots 111 and reserved blind holes 112 on the chassis 1, different options are provided for the connection between the chassis 1 and the external wall, so that users can choose the most suitable installation scheme according to the actual installation environment, thereby improving the actual use adaptability and installation flexibility of the chassis 1.
[0035] In addition, the cavity wall of the receiving cavity 11 is provided with two or more connecting pins 113, which are evenly distributed along the circumference of the chassis 1. The connecting pins 113 are used to engage with the connecting grooves provided on the lampshade to achieve quick assembly and disassembly between the lampshade and the chassis 1, thereby facilitating the installation and maintenance of the ceiling light 100; when the lampshade is installed on the chassis 1, the lampshade covers the opening of the receiving cavity 11. The connecting pins 113 and the chassis 1 can be fixedly connected by welding or riveting.
[0036] The mounting boss 12 has placement areas 120, the number of which is equal to the number of light source modules 2. Preferably, there are three to eight placement areas 120; correspondingly, there are three to eight groups of light source modules 2, with each group of light source modules 2 corresponding to one of the placement areas 120. Furthermore, the pressure plates 22 of the multiple groups of light source modules 2 are connected end-to-end to form a polygon, and correspondingly, the mounting boss 12 is polygonal in shape. This design allows the number of light source modules 2 to be flexibly adjusted according to the lighting power and requirements of the ceiling light 100, improving the practicality and applicability of the ceiling light 100. In this embodiment, for example, there are four placement areas 120 and four light source modules 2, with the four light source modules 2 connected end-to-end in a rectangular distribution, and the mounting boss 12 is rectangular in shape.
[0037] Each placement area 120 has a positioning protrusion group 121 and a tongue piece 122 on the top surface of the mounting boss 12 (the side near the opening of the receiving cavity 11). The positioning protrusion group 121 and the tongue piece 122 are integrally formed with the chassis 1 by stamping process.
[0038] The light source module 2 includes a light source plate 21 and a pressure plate 22. The light source plate 21 includes a light-emitting component 211 and a plate body 212, with the light-emitting component 211 mounted on the plate body 212. The plate body 212 is provided with a positioning groove group 2121 and a first through groove 2122, both of which penetrate the plate body 212. When the light source plate 21 is assembled with the chassis 1, the light source plate 21 is placed in the corresponding placement area 120, and the positioning groove group 2121 on the plate body 212 engages with the positioning protrusion group 121, while the tongue 122 passes through the first through groove 2122.
[0039] The pressure plate 22 includes a pressing part 221 and a wiring part 222. The pressing part 221 is provided with a receiving groove. The bottom wall of the receiving groove is provided with a clearance position 2211 and a second through groove 2212, and the clearance position 2211 and the second through groove 2212 penetrate through the bottom wall of the receiving groove. When the pressure plate 22 is assembled with the light source plate 21 and the chassis 1, the pressure plate 22 will cover the light source plate 21, and the plate body 212 will be located in the receiving groove and the clearance cavity 2221. The light-emitting component 211 passes through the corresponding clearance position 2211 on the pressing part 221, and the tongue 122 passes through the second through groove 2212. When the chassis 1 and the light source module 2 are fixed, the part of the tongue 122 that extends out of the second through groove 2212 is bent (e.g., bent at 90°), so that the tongue 122 fits and presses against the top surface of the pressing part 221.
[0040] With the cooperation of the tongue 122 with the first through slot 2122 and the second through slot 2212, the tongue 122 can act as a positioning pin to prevent the light source board 21 and the pressure plate 22 from coming off the placement area 120, and also provide feasibility for the subsequent synchronous fixing of the multi-light source module 2 and the chassis 1. On the other hand, with the cooperation of the tongue 122, all the tongues 122 on the chassis 1 of the processing equipment can be bent at the same time to achieve the simultaneous fixing of the multi-light source module 2 and the chassis 1, thereby greatly improving the assembly efficiency.
[0041] Furthermore, since the tongue 122 is integrally formed from the chassis 1 through a stamping process, compared with the traditional light source module fixing structure, this light source module fixing structure 101 does not require additional bolts to fix the light source module 2 and the chassis 1, saving the number of parts required for assembly, thereby significantly reducing production costs, and also significantly reducing the defect rate during the assembly process.
[0042] Furthermore, the positioning protrusions 121 on the chassis 1 and the positioning grooves 2121 on the light source plate 21 can better position the light source plate 21 and the chassis 1, and limit the light source plate 21 during the bending process of the tongue 122, so as to ensure that the light source plate 21 is always accurately fixed in the desired position during the bending process of the tongue 122, thereby ensuring the installation position accuracy of the light source plate 21 and the pressure plate 22 (the installation position accuracy of the pressure plate 22 can be achieved by the snap-fit connection between the plate body 212 of the light source plate 21 and the receiving groove on the pressing part 221 of the pressure plate 22).
[0043] Preferably, the positioning protrusion group 121 includes two positioning protrusions 1211; the two positioning protrusions 1211 are distributed at both ends of the plate body 212 along its length. Correspondingly, the positioning groove group 2121 includes two positioning grooves 21211; the two positioning grooves 21211 are located at both ends of the plate body 212 along its length, so that one positioning groove 21211 can engage with one positioning protrusion 1211. This design ensures the reliability of positioning and limiting the light source plate 21, simplifies the structure of the chassis 1 and the light source plate 21 to the greatest extent, reduces production costs, and ensures the structural strength of the light source plate 21.
[0044] Furthermore, each placement area 120 contains two tongues 122, and the two tongues 122 are located between two positioning protrusions 1211; in addition, a large distance is preferably maintained between the two tongues 122. Correspondingly, the plate 212 is provided with two first through slots 2122, which correspond one-to-one with the two tongues 122, so that one tongue 122 passes through the corresponding first through slot 2122; the pressing part 221 is provided with two second through slots 2212, which correspond one-to-one with the two tongues 122, so that one tongue 122 passes through the corresponding second through slot 2212. This design can ensure the reliability of fixing the light source module 2 to the chassis 1, and can simplify the structure of the chassis 1, the light source plate 21 and the pressure plate 22 to the greatest extent, reduce production costs, and ensure the structural strength of the chassis 1, the light source plate 21 and the pressure plate 22.
[0045] In order to ensure that the pressure plate 22 is subjected to uniform force and to ensure the stability and firmness of the fixed connection between the light source module 2 and the chassis 1, when the two tongues 122 in the same placement area 120 are bent, the bending directions of the two tongues 122 are controlled to be opposite.
[0046] The wiring section 222 is provided with a cavity 2221 and a wire passage groove 2222, and the wire passage groove 2222 communicates with the cavity 2221. The pressure plate 22 includes two wiring sections 222, which are located at both ends of the pressing section 221. When the pressure plate 22 covers the light source plate 21, a positioning protrusion 1211 is located in the cavity 2221 of one wiring section 222. Two wiring sections 222 are provided on the pressure plate 22, which makes it easier to connect adjacent pressure plates 22 when multiple pressure plates 22 are connected end to end. This also allows each positioning protrusion 1211 to be located outside the pressing part 221 of the pressure plate 22 and housed within the wiring section 222. This prevents the pressure plate 22 from warping when the positioning protrusion 1211 is higher than the plate body 212 of the light source board 21, and avoids gaps between the pressure plate 22 and the mounting boss 12, thus better fixing and protecting the light source board 21. For example, Figure 3As shown, the cable trays 2222 of the two cable routing sections 222 connected by the two adjacent pressure plates 22 form a cable routing channel 2220.
[0047] like Figure 4 As shown, when there are multiple light source modules 2, adjacent light source boards 21 need to be connected by cables to achieve series connection between multiple light source boards 21. The cavity 2221 is provided to accommodate these cables, preventing them from being exposed, improving the regularity of the light source module fixing structure 101, and preventing the pressure plate 22 from being pushed when the cables are stored inside the pressure plate 22, thus avoiding warping of the pressure plate 22. It also reduces the undesirable straightening and restoration of the tongue 122 after bending. The cable passage 2220 is used for the cables connecting the power module 102 and the light source board 21 to pass through, preventing the pressure plate 22 from warping or deforming.
[0048] The power module 102 is electrically connected to the first and last light source boards 21 of the interconnected light source boards 21, and is also electrically connected to the terminal block 103. The terminal block 103 improves the reliability and safety of the connection between the power module 102 and the external power supply cable. Both the power module 102 and the terminal block 103 are mounted on the chassis 1, and preferably both are located inside the mounting boss 12, that is, the mounting boss 12 is arranged around the power module 102 and the terminal block 103.
[0049] In addition, the power module 102 and the wiring terminal 103 are both located in the space enclosed by the chassis 1 and the lampshade. This design can improve the overall integration of the ceiling light 100, while avoiding the exposure of the power module 102 and wiring terminal 103 components, thereby preventing the exposed components from adversely affecting the safety and appearance of the ceiling light 100.
[0050] In summary, the design of the light source module fixing structure 101 of the ceiling light 100 can effectively reduce production costs, improve production efficiency, and reduce the defect rate during the production process.
[0051] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
