Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, and more particularly to a modular track light and its rotating structure. Background Technology

[0002] In the field of lighting, in order to achieve flexible application of lamps, the lamp body is designed to be rotatable, especially track lights, which are equipped with track adapters that work with the power supply track. The lamp body and the track adapter are connected by a rotating arm. Generally, the lamp body can rotate relative to the rotating arm, and the rotating arm can rotate relative to the track adapter, thus enabling the lamp body to provide multi-angle lighting.

[0003] The commonly used swing arm structure is mainly achieved through the following means in order to make the swing arm have a certain damping: (1) Using the connection technology of threaded pair, but in order to prevent the nut from loosening after multiple rotations and causing functional failure, this technology not only requires the addition of stop shims and thread glue, but also requires the addition of plastic shims to increase friction, resulting in additional cost. In addition, the connection of threaded pair cannot guarantee the stability and reliability of the swing arm damping force, resulting in batch rework and serious quality problems; (2) Using standard dampers, it is necessary to add a connection structure with the damper on the lamp body and swing arm, making the lamp body structure design more complicated, occupying the space of the lamp, and increasing the assembly cost, which is not conducive to the large-scale production of the product.

[0004] Furthermore, the existing track lights have a complex design that cannot maximize the efficiency of the heat sink. Under the same power conditions, a larger heat dissipation area is required, increasing the size of the heat sink. Due to the large number of components, a significant amount of manual assembly is needed, making large-scale automated production impossible. As a result, track lights are expensive and have a low cost-performance ratio.

[0005] Therefore, those skilled in the art are dedicated to developing a modular track light and its rotating structure, optimizing the rotating structure, and minimizing the number of parts in the product to achieve modular assembly. Summary of the Invention

[0006] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is the disadvantages of the existing track lights, such as complex structure, high cost of rotating structure, and many parts, which are not conducive to mass production.

[0007] To achieve the above objectives, the present invention provides a rotating structure for a track light, including a rotating arm rotatably connected between a track adapter and a power supply housing, and a rotating groove formed on the power supply housing and installed in conjunction with the rotating arm. The rotating arm has a first rotating shaft at one end along its length, and the rotating groove includes a mounting groove. The first rotating shaft is rotatably fitted into the mounting groove. An elastic element is provided between the end faces of the first rotating shaft and the mounting groove. The elastic element includes a pressing portion that bends and deforms as the first rotating shaft enters the mounting groove to elastically support the first rotating shaft and provide friction.

[0008] Furthermore, a rotating groove is formed on one side of the power supply housing. When the rotating arm is in the retracted state, it is located in the rotating groove. The rotating groove includes two oppositely arranged mounting walls, which are respectively located on both sides of the rotating arm. The mounting groove is provided along the mounting wall. A rotating block is formed by protrusions on both sides of the first rotating shaft. The rotating block is rotatably embedded in the mounting groove on the corresponding side. The pressing part elastically abuts between the rotating block and the mounting groove.

[0009] Furthermore, the rotating block is provided with a guide surface and a stop surface along the length of the rotating arm. The guide surface is inclined towards the inner side of the rotating arm, and the installation direction of the rotating arm relative to the rotating groove is along its length. During installation, the guide surface slides into the mounting groove first. When the arm is in the engagement state, the guide surface abuts against the elastic element, and the stop surface abuts against the mounting groove.

[0010] Furthermore, the mounting groove includes a first groove and a second groove, and an mounting gap is provided between the first groove and the second groove. The elastic member also includes a fixing part, which is fixedly installed in the mounting gap. The crimping part and the fixing part are connected, and the end of the crimping part abuts against the edge of the first groove or the second groove.

[0011] Furthermore, the power supply housing includes a first housing and a second housing, a rotating groove is formed on the first housing, a mounting groove is disposed on the first housing and close to the second housing, and the second housing covers the first housing and supports the first rotating shaft.

[0012] Furthermore, a second rotating shaft is provided at the other end of the rotating arm along the length direction, and a rotating ring is provided around the center line of the second rotating shaft and rotatably connected to the track adapter. The rotating arm passes through the bottom side of the track adapter, and the rotating ring and the fitting groove in the track adapter are tightly connected.

[0013] Furthermore, a cable passage cavity is provided through the rotating arm, through which the first wire connects to the track adapter and the power supply housing.

[0014] The present invention also provides a modular track light, including a track adapter and a light body, wherein the track adapter and the light body are provided with the aforementioned rotating structure, wherein the light body includes a cylindrical body and a power supply housing, a heat sink, a COB mounting base and an optical component arranged sequentially in the cylindrical body, wherein the power supply housing is provided with a drive circuit board, and the COB mounting base is provided with a COB light source, which includes a substrate and an LED chip, one side of the substrate is in contact with the heat sink, the LED chip is arranged facing the optical component, and a socket electrically connected to the LED chip is provided on the outside of the COB mounting base, and the socket is inserted into the heat sink, the heat sink is passed through by a second wire, and the second wire connects the socket and the drive circuit board.

[0015] Furthermore, the COB mounting base includes a base plate, a COB light source, a PCB board, and a cover plate arranged in sequence. The socket is connected to the PCB board. Conductive contacts are provided on the substrate. A conductive sheet is connected to the PCB board. One end of the conductive sheet is electrically connected to the PCB board, and the other end is bent toward one side of the substrate and abuts against the conductive contact. The base plate and the cover plate are connected and clamp the PCB board and the substrate, so that the conductive sheet and the conductive contact are electrically connected.

[0016] Furthermore, there are two conductive contacts, which are distributed on opposite sides along the outer periphery of the LED chip. Each conductive contact is connected to a conductive sheet and then connected to different electrodes of the socket via the PCB board.

[0017] Technical effects:

[0018] (1) The present invention achieves the damping function by pressing the elastic element with the rotating arm to generate elastic deformation and friction between the elastic element and the first rotating shaft of the rotating arm. Since the stress obtained by directly utilizing the deformation of the elastic element is used, the damping force of the rotating arm is reliable and stable.

[0019] (2) The present invention adopts a modular structure, decomposes the product into different functional modules, and adopts a built-in power supply in terms of structure. High thermal conductivity pure aluminum is used as the heat carrier, so that the lamp body has a small size and good heat dissipation.

[0020] (3) The elastic component has a simple structure and the pressing operation is simple and reliable. The modular design of the lamps reduces the number of parts as much as possible, simplifies assembly, and allows for plug-in connection between the functional modules, thereby reducing the cost of the track lamp of the present invention and improving production efficiency.

Detailed Implementation

[0029] like Figure 1 The diagram shows a rotating structure for a track light according to the present invention, including a rotating arm 1, which is suitable for connecting between a track adapter 2 and a lamp body 300. On the one hand, it provides a rotating connection function, and on the other hand, it has wiring inside to supply power to the lamp.

[0030] In an embodiment of the present invention, the rotating structure includes a cooperating rotating arm 1 and a rotating groove 4. The lamp body 300 includes a power housing 3 disposed at its end. The rotating arm 1 is rotatably connected between the track adapter 2 and the power housing 3. The rotating groove 4 is formed on the power housing 3. One end of the rotating arm 1 along its length is provided with a first rotating shaft 11. The rotating groove 4 includes a mounting groove 5, and the first rotating shaft 11 is rotatably fitted into the mounting groove 5. Figure 1In the rotating structure, the axis of the first rotating shaft 11 is perpendicular to the center line of the rotating arm 1. When the rotating arm 1 is arranged in a vertical direction, the power supply housing 3 can rotate along a vertical plane. An elastic member 6 is provided between the end face of the first rotating shaft 11 and the mounting groove 5. The elastic member 6 includes a pressing part 61, which bends and deforms as the first rotating shaft 11 enters the mounting groove 5 to elastically support the first rotating shaft 11 and provide friction.

[0031] The elastic element 6 can be made of elastic material, such as a metal sheet, preferably a steel sheet, or an elastic metal wire. Through its elastic deformation performance, after being compressed and bent, the elastic restoring force makes the elastic element 6 abut against the first rotating shaft 11 to achieve the damping function. After the first rotating shaft 11 rotates relative to the rotating groove 4, it can stop at the required angle.

[0032] like Figure 2 The rotating groove 4 is opened on one side of the power supply housing 3. When the rotating arm 1 is in the retracted state, it is located in the rotating groove 4. The rotating groove 4 includes two oppositely arranged mounting walls 41, which are respectively located on both sides of the rotating arm 1. The mounting groove 5 is arranged along the mounting wall 41. A rotating block 12 protrudes from each side of the first rotating shaft 11. The rotating block 12 is rotatably embedded in the mounting groove 5 on the corresponding side. The pressing part 61 elastically abuts between the rotating block 12 and the mounting groove 5. Specifically, when the rotating arm 1 is installed, it moves along its length direction. The pressing part 61 is arranged between the opposite end faces of the rotating block 12 and the mounting groove 5 on each side. After the rotating block 12 enters the mounting groove 5, the pressing part 61 is clamped therebetween.

[0033] The mounting grooves 5 are located on both sides of the first rotating shaft 11 and opposite to the rotating block 12. The rotating block 12 is configured to slide into the mounting grooves 5 and engage within them, thus the mounting grooves 5 on both sides clamp the first rotating shaft 11 inward. Figure 1 and Figure 3 The rotating block 12 is provided with a guide surface 121 and a stop surface 122 along the length of the rotating arm 1. The guide surface 121 is inclined towards the inner side of the rotating arm 1. The mounting direction of the rotating arm 1 relative to the rotating groove 4 is along its length. During installation, the rotating arm 1 slides inward from the outside of the power supply housing 3 along the rotating groove 4. Then, the guide surface 121 slides into the mounting groove 5. When it is in the engaged state, the guide surface 121 abuts against the elastic member 6, and the stop surface 122 abuts against the mounting groove 5. Preferably, the mounting groove 5 has a snap-fit ​​block 51 at one end facing outward. The snap-fit ​​block 51 has a wedge-shaped surface 511 on one side facing the guide surface 121, which is adapted to the guide surface 121 to facilitate sliding in. The other side has a positioning surface 512, which is suitable for abutting against the stop surface 122 after installation.

[0034] In one embodiment of the present invention, the mounting groove 5 includes a first groove 52 and a second groove 53, such as Figure 2 and Figure 3As shown, after the rotating block 12 is installed, the guide surface 121 abuts against the first groove 52, and the anti-reverse surface 122 abuts against the second groove 53. An installation gap 54 is provided between the first groove 52 and the second groove 53. The installation gap 54 includes an installation step 541 formed inside the installation groove 5. Each side of the installation step 541 is connected to the end of a first groove 52. The elastic member 6 also includes a fixing part 62. A pressing part 61 is connected to the fixing part 62. Two pressing parts 61 are provided, located at opposite ends of the fixing part 62, corresponding to one first groove 52 on each side. The end of the pressing part 61 abuts against the edge of the first groove 52. The fixing part 62 is mounted on the installation step 541. For easy positioning, the installation step 541 also has a protrusion 542 facing the fixing part 62. The protrusion 542 abuts against the side of the fixing part 62 to prevent the elastic member 6 from sliding or shifting along the installation step 541 in the installation gap 54. The first groove 52 and the second groove 53 are used to distinguish the two separated parts. When the corresponding guide surface 121 is installed against the second groove 53, the pressing part 61 is set to abut against the second groove 53.

[0035] Preferably, the power supply housing 3 is configured as an assemblable structure, including a first housing 31 and a second housing 32, such as... Figure 3 A rotating groove 4 is formed on the first housing 31, and a mounting groove 5 is provided on the first housing 31 and close to the second housing 32. The rotating arm 1 is installed between the first housing 31 and the second housing 32 and enters the rotating groove 4. The second housing 32 covers the first housing 31 and supports the first rotating shaft 11. Each of the first housing 31 and the second housing 32 has a heat dissipation hole 33 to facilitate heat convection and heat dissipation.

[0036] Furthermore, a second rotating shaft 13 is provided at the other end of the rotating arm 1 along its length, which is configured to be assembled and connected to the track adapter 2. A rotating ring 14, rotatably connected to the track adapter 2, is provided around the center line of the second rotating shaft 13. The rotating arm 1 passes through the bottom side of the track adapter 2, and the rotating ring 14 is tightly fitted into the fitting groove 21 within the track adapter 2. For example... Figure 1 The track adapter 2 includes a left outer shell 22 and a right outer shell 23 spliced ​​together in a direction perpendicular to the center line of the second rotating shaft 13. Each of the left outer shell 22 and the right outer shell 23 is provided with a corresponding interlocking groove 21 on the rotating ring 14. After assembly and connection, the rotating ring 14 is clamped to achieve a tight fit. A wire passage cavity 15 is provided through the rotating arm 1, which opens through both ends of the rotating arm 1. A first wire 301 is provided to connect the track adapter 2 and the power supply housing 3 through the wire passage cavity 15, which facilitates hiding the wire inside the lamp and avoids the wire from getting tangled when the rotating arm 1 rotates.

[0037] After the power supply housing 3 and the rotating arm 1 are assembled, they form a modular structure. Because the assembly requires few parts and can be easily assembled with the power adapter 2, it is suitable for use in the automated production of lighting fixtures.

[0038] Based on the aforementioned rotating structure, the present invention also provides a modular track light, including a track adapter 2 and a light body 300, wherein a rotating structure is provided between the track adapter 2 and the light body 300.

[0039] like Figure 4 The lamp body 300 includes a cylindrical body 303 and a power supply housing 3, a heat sink 304, a COB mounting base 7, and an optical component 305 sequentially disposed within the cylindrical body 303. The power supply housing 3 contains a drive circuit board 34, and the COB mounting base 7 contains a COB light source 71, which includes a substrate 711 and an LED chip 712. One side of the substrate 711 is in contact with the heat sink 304, and the LED chip 712 faces the optical component 305. A socket 75 electrically connected to the LED chip 712 is disposed on the outer side of the COB mounting base 7, and the socket 75 is inserted into the heat sink 304. A second wire 302 passes through the heat sink 304 and connects the socket 75 and the drive circuit board 34. The second wire 302 is covered by a wire sheath 3021, and one end of the wire sheath 3021 is fixedly connected to the bottom surface of the power supply housing 3. A mounting cavity 3041 adapted to the wire protection housing 3021 is provided through the heat sink 304. One end of the second wire 302 passes through the power supply housing 3 and is connected to the drive circuit board 34. In this way, together with the first wire 301, electricity is conducted from the track adapter 2 to the COB light source 71 to realize illumination.

[0040] In one specific implementation, the heat sink 304 uses high thermal conductivity pure aluminum as the heat carrier to maximize the heat dissipation area. Further surface treatment maximizes the radiation surface for heat dissipation, achieving rapid heat conduction and dissipation. Under the same power conditions, this results in the smallest lamp body volume and the lowest cost.

[0041] like Figure 5As shown, the COB mounting base 7 includes a base plate 73, a COB light source 71, a PCB board 74, and a cover plate 76 arranged sequentially. The socket 75 is connected to the PCB board 74. A conductive contact 72 is provided on the substrate 711. A conductive sheet 77 is connected to the PCB board 74. One end of the conductive sheet 77 is electrically connected to the PCB board 74, and the other end is a free end that bends toward the substrate 711. The end of the free end abuts against the conductive contact 72. A light outlet is provided on the cover plate 76. The LED chip 712 is exposed through the light outlet of the cover plate 76. The base plate 73 and the cover plate 76 are connected and clamp the PCB board 74 and the substrate 711, so that the free end of the conductive sheet 77 and the conductive contact 72 are connected. The socket 75 is fixedly connected to the PCB board 74 by solder and is in contact with the circuit on the PCB board 74. There are two conductive contacts 72, which are distributed on opposite sides along the outer periphery of the LED chip 712. Each conductive contact 72 is connected to a conductive sheet 77 and is connected to different electrodes of the socket 75 through the PCB board 74.

[0042] The modular track light of this invention integrates the rotating arm 1 and the power supply housing 3. The heat sink 304 is connected to the assembled power supply housing 3 and the COB mounting base 7 via a cable protection housing 3021 and a socket 75 on both sides. The COB mounting base 7 and the optical component 305 are arranged adjacent to each other. Figure 6 As shown, the connection method of each module is simple and suitable for rapid assembly.

[0043] Due to the modular and integrated design, the number of parts in the product of this invention is reduced as much as possible, the assembly process is reduced, and the functional modules are connected by plug-in interfaces, which can quickly realize the automated assembly of the whole lamp, greatly improve production efficiency, reduce product costs, and enhance product competitiveness.

[0044] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
