A type of track lighting fixture

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411716128.8, filed on November 27, 2024, entitled "A Track Lighting Fixture", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to the field of lighting technology, and in particular to a track lighting fixture. Background Technology

[0004] With the development of the retail industry, shelf lighting fixtures are increasingly widely used in supermarkets, shopping malls, and other venues. Their main purpose is to better display merchandise, guide customer attention, and enhance the shopping experience. Existing shelf lights or similar lighting devices are typically designed to accurately illuminate the shelves on either side of the shelf to highlight merchandise and attract customer attention. These fixtures generally include a light source (such as an LED light) and a reflector or reflector to direct the beam.

[0005] However, traditional shelf lighting designs have certain limitations. Specifically, structurally, the light source is typically located in the center of a reflector cup, using the reflector's reflection to effectively illuminate the shelves on either side. While this design achieves the desired lighting effect, in practical applications, the connection between the light source and the reflector cup often relies on a thin, transparent insulating plastic layer for electrical safety, leading to insufficient stability in the overall structure of the lighting fixture. Especially after prolonged use or exposure to minor external vibrations, the light source may loosen or shift, affecting lighting quality and the fixture's lifespan.

[0006] Furthermore, due to intense market competition, manufacturers often prioritize cost reduction, making the use of cheaper and simpler insulation materials a common choice. While this helps control production costs, it also exacerbates the aforementioned structural instability issues.

[0007] Therefore, there is an urgent need in the market for an improved shelf lighting design to overcome the shortcomings of existing technologies, provide a more robust and reliable structure, ensure long-term stability and safety, and meet the requirements of high efficiency and energy saving. Summary of the Invention

[0008] This invention addresses the problems of existing technologies by providing a track lighting fixture. By setting up a lens to assist in adjusting the beam of the light source, accurate lighting control is achieved through the cooperation of the lens and the reflector. Furthermore, the central axis of the light source does not coincide with the central axis of the reflector, meaning that the position of the light source does not need to be in the center of the reflector. The position of the light source can be adjusted according to the illuminated object such as a shelf, making the structure more flexible and stable.

Detailed Implementation

[0050] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0051] Example 1:

[0052] This embodiment provides a track lighting fixture, as shown in Figures 1 to 9, including a lamp holder 01, a lamp panel 02, a lens device 03, and a reflector 04. The lamp panel 02 is mounted on the lamp holder 01. The lens device 03 is provided with multiple lenses 05 arranged in an array. The reflector 04 is provided with multiple reflector cups 06 arranged in an array. The lamp panel 02 is provided with multiple LED beads 014 arranged in an array. Each LED bead 014 has a lens 05 corresponding to its light emission direction. A light hole is opened in the center of each reflector cup 06. Each lens 05 is provided with a reflector cup 06. The lens 05 passes through the light hole and is located in the reflector cup 06. The central axis of the lens 05 is coaxial with the central axis of the reflector cup 06. The central axis of the light emission of the LED bead 014 is not coaxial with the central axis of the lens 05.

[0053] Specifically, as shown in Figure 4, the central axis a of LED 014, the central axis b of lens 05, and the central axis c of reflector 06 are shown. After lens 05 and reflector 06 are assembled, lens 05 and reflector 06 are set coaxially, that is, the central axis of lens 05 coincides with the central axis of reflector 06, while the central axis of LED 014 does not coincide with the central axis of reflector 06, as shown in Figure 3. LED 014 is set to the left or right of the central axis of reflector 06, and adjusted according to whether the light beam illuminates the left or right side. In other words, the angle of the light beam can be changed by setting the position of LED 014, i.e., the light source, and then, with the lens 05 and reflector 06, the light source illumination effect shown in Figure 9 can be achieved.

[0054] More specifically, in this embodiment, the lamp board 02 is provided with an array of LED beads 014, i.e., an array of light sources. The LED beads 014 are arranged in a 3x3 array as one LED bead module. Multiple LED bead modules are arranged to form the structure shown in Figures 1 and 22. The arrangement of the LED beads in each LED bead module is shown in Figure 22. The LED beads 014 are located to the right or left of the central axis of the reflector cup 06. In this embodiment, the LED beads of adjacent modules are symmetrically arranged, as shown in Figure 22, thereby forming the lighting effects shown in Figures 9 and 21. Each LED bead 014 in this embodiment is provided with a lens 05 and a reflector cup 06. The lens device 03 is an integrally formed structure. As one implementation, all lenses 05 in this embodiment can be set as one piece; as shown in Figures 7 and 8. As another implementation, the lens device 03 in this embodiment can be set to include multiple lens structures, as shown in Figure 8. Multiple lens structures are spliced ​​together to form the lens device 03. Setting it to multiple lens structures facilitates production and assembly. In actual use, it can be set according to the specific situation.

[0055] As shown in Figure 7, the structure of the reflector 04 is the same as that of the lens device 03. It can be set as a completely one-piece structure or it can be formed by multiple spliced ​​structures. The axial cross-section of the reflector cup 06 is trapezoidal, and the radial cross-section is quadrilateral, circle, etc. That is, the shape of the reflector cup 06 can be similar to a funnel or a trapezoidal shape as shown in Figure 7. It can be set according to actual needs. This embodiment does not impose any restrictions.

[0056] Furthermore, in this embodiment, the lens device 03 is injection molded, and the reflector cup 06 device is also injection molded. Therefore, the structure of the lens 05 and the reflector cup 06 is more robust and easier to assemble and fix. Compared with the thin-layer plastic insulation structure of the prior art, the structure of the lens 05 makes the structure of the track light in this embodiment more stable and less prone to loosening, thereby maintaining the accuracy of the light source illumination.

[0057] As shown in Figures 5 and 6, the specific installation structure of this embodiment is as follows: the lamp holder 01 is provided with an installation cavity 07, and the lamp plate 02, lens 05 and reflector cup 06 are all located in the installation cavity 07; rectangular grooves 08 are provided on both sides of the installation cavity 07, and the two sides of the lamp plate 02 are respectively engaged in the rectangular grooves 08.

[0058] Specifically, during installation, the lamp plate 02 is inserted into one end of the mounting cavity 07 of the lamp holder 01, so that both sides of the lamp plate 02 are engaged in the rectangular grooves 08. Similarly, the lens device 03 is also inserted into the mounting cavity 07, so that the lens 05 is positioned above the lamp plate 02. Furthermore, fixing strips 013 protrude from both sides of the mounting cavity 07, and the two sides of the lens device 03 respectively abut against the two fixing strips 013, thereby stabilizing the installation of the lens device 03. Multiple hooks 09 are installed on both sides of the reflector 04, as shown in Figures 5 and 7. Limiting slots 010 are opened on both sides of the mounting cavity 07. The reflector 04 is assembled into the mounting cavity 07, and the hooks 09 are engaged in the limiting slots 010, thereby fixing the reflector cup 06 to the lamp holder 01. Furthermore, the reflector cup 06 is provided with several positioning posts 011 on the side near the lens 05. The lens 05 is provided with several first positioning slots 012 for assembling the positioning posts 011. After the lens 05 and the reflector cup 06 are both installed on the lamp holder 01, the positioning posts 011 of the reflector cup 06 are inserted into the first positioning slots 012 of the lens 05, making the assembly between the reflector device 04 and the lens device 03 more stable.

[0059] In this embodiment, a lamp panel 02, a lens 05, and a reflector 06 are assembled sequentially. The light source is not positioned at the center of the light aperture of the reflector 06. Therefore, by adjusting the position of the light source and by cooperating with the lens 05 and the reflector 06, the light beam can be adjusted so that the light source can more accurately illuminate both sides of the track light. As shown in Figure 9, which is the light source illumination diagram tested in this embodiment, a very good lighting effect can be achieved. Furthermore, in addition to assisting in adjusting the light beam, the lens 05 can also be better fixed between the lamp panel 02 and the reflector 06. Compared with ordinary insulating plastic thin layers, the lens 05 is better fixed, thereby improving the assembly stability of the track light.

[0060] Example 2:

[0061] The difference between this embodiment and Embodiment 1 is that the reflector 04 is a vacuum-formed integrated structure. The vacuum-formed reflector 04 has a lower cost, which helps to reduce the production cost of the track light.

[0062] Example 3:

[0063] The driver provided in this embodiment, as shown in Figures 10 to 15, includes a first driving mechanism, a second driving mechanism, and an intermediate assembly 1;

[0064] The first driving mechanism includes a first housing, a first conductive connection component 3, and a first driving component. The first housing has a first conductive cavity and a first driving cavity. The first conductive connection component 3 is electrically connected to the first driving component. The first conductive connection component 3 is rotatably mounted in the first conductive cavity, and the first driving component is fixedly mounted in the first driving cavity. The first conductive connection component 3 is used for electrical connection with an external track. The second driving mechanism includes a second housing, a second conductive connection component 4, and a second driving component. The second housing has a second conductive cavity and a second driving cavity. The second conductive connection component 4 is rotatably mounted in the second conductive cavity, and the second driving component is fixedly mounted in the second driving cavity. The second conductive connection component 4 is electrically connected to the second driving component. The second conductive connection component 4 is used for electrical connection with an external track.

[0065] Specifically, as shown in Figure 11, this embodiment is configured with a three-live-wire and three-neutral-wire drive structure according to actual needs. The first conductive connection component 3 includes a first connection shell 2, a first live-wire conductive sheet, and a first neutral-wire conductive sheet. The first live-wire conductive sheet and the first neutral-wire conductive sheet are both installed in the first connection shell 2, which is installed in the first conductive cavity. The first live-wire conductive sheet and the first neutral-wire conductive sheet are both electrically connected to the first drive component. The second conductive connection component 4 includes a second connection shell 5, a second live-wire conductive sheet, a third live-wire conductive sheet, a second neutral-wire conductive sheet, and a third neutral-wire conductive sheet. The second connection shell 5 is installed in the second conductive cavity. The second live-wire conductive sheet, the third live-wire conductive sheet, the second neutral-wire conductive sheet, and the third neutral-wire conductive sheet are all installed in the second connection shell 5. The second live-wire conductive sheet, the third live-wire conductive sheet, the second neutral-wire conductive sheet, and the third neutral-wire conductive sheet are all electrically connected to the second drive component. The first live wire conductive sheet, the first neutral wire conductive sheet, the second live wire conductive sheet, the third live wire conductive sheet, the second neutral wire conductive sheet, and the third neutral wire conductive sheet are all made of conductive metal sheets. The first connecting shell 2 and the second connecting shell 5 are respectively provided with corresponding slots for assembling the conductive metal sheets. The first connecting shell 2 and the second connecting shell 5 are rotatable. When this embodiment is assembled onto the track, by rotating the first connecting shell 2 and the second connecting shell 5, the corresponding conductive metal sheets rotate out of the first and second outer shells and make contact with the track to achieve electrical connection. When it is necessary to remove the driver of this embodiment from the track, by rotating the first connecting shell 2 and the second connecting shell 5, all the conductive metal sheets rotate into the first and second outer shells, disconnecting the driver from the track, and thus the driver can be separated from the track. The rotation function of the first conductive connection component 3 and the second conductive connection component 4 in this embodiment is prior art, which can be controlled by the handles provided on the first connecting shell 2 and the second connecting shell 5, and will not be described in detail here.

[0066] Furthermore, because two conductive connection components are provided, the first conductive connection component 3 is a two-wire structure and the second conductive connection component 4 is a four-wire structure, which can be combined to form a six-wire drive structure. Alternatively, the first conductive connection component 3 can be made into a four-wire structure according to actual needs, thus forming an eight-wire drive structure, realizing the switching and adjustment of the drive structure and making it more flexible to use.

[0067] The assembly structure of the first drive mechanism in this embodiment is as follows:

[0068] The first outer shell, as shown in Figures 11 to 14, includes a first upper shell 11 and a first lower shell 12. The first upper shell 11 is provided with a first retaining ring 13 and a first retaining groove 16, and the first lower shell 12 is provided with a first retaining block 15 and a first retaining hook 14. When the first upper shell 11 and the lower shell are assembled, the first retaining block 15 engages with the first retaining ring 13, and the first retaining hook 14 engages with the first retaining groove 16. That is, after the first conductive connection component 3 and the first driving component are fixed to the first upper shell 11 or the first lower shell 12, the first upper shell 11 and the first lower shell 12 are mutually engaged and fixed by the first retaining ring 13, the first retaining hook 14, the first retaining block 15 and the first retaining groove 16, thus completing the assembly and fixing.

[0069] The first conductive connection assembly 3, as shown in Figure 12, is installed into the first conductive cavity. The first upper shell 11 and the first lower shell 12 have holes for the first live wire conductive piece and the first neutral wire conductive piece to extend out.

[0070] The first driving component, as shown in Figure 12, includes a first circuit board 28 and components mounted on the circuit board. The circuit board is provided with corresponding functional circuits. The first live wire conductive piece and the first neutral wire conductive piece of the first conductive connection component 3 are electrically connected to the first circuit board 28 to supply power to the first driving component. The first circuit board 28 can also be electrically connected to the second driving component through wires.

[0071] The assembly structure of the second drive mechanism in this embodiment is as follows:

[0072] The second outer shell, as shown in Figures 11 to 14, includes a second upper shell 17 and a second lower shell 18. A positioning ridge 19 is provided at the connection between the second lower shell 18 and the second upper shell 17. Positioning grooves 20 for assembling the limiting ridge are provided on both sides of the second upper shell 17. After the second upper shell 17 and the second lower shell 18 are positioned and assembled, they can be locked together by screws and other parts.

[0073] As shown in Figure 12, the second conductive connection assembly 4 is installed into the second conductive cavity. The second upper shell 17 and the second lower shell 18 have holes for the second live wire conductive sheet, the third live wire conductive sheet, the second neutral wire conductive sheet and the third neutral wire conductive sheet to extend out, so as to allow the second conductive connection assembly 4 to rotate.

[0074] The second driving component, as shown in Figure 12, includes a second circuit board 29 and a level adjustment module 27. The second circuit board 29 is provided with several conductive protrusions for contacting the second live wire conductive sheet, the third live wire conductive sheet, the second neutral wire conductive sheet, and the third neutral wire conductive sheet to achieve electrical connection. The level adjustment module 27 is signal connected to the second circuit board 29 to realize the level adjustment of the lighting, such as brightness adjustment. The level adjustment module 27 is prior art and will not be described in detail here. Furthermore, the intermediate assembly 1 is equipped with a first positioning insert 30, and the second driving component includes a second driving circuit board. The second driving circuit board is equipped with a second positioning insert 31, and the second positioning insert 31 has a positioning slot. The first positioning insert 30 is fitted into the positioning slot to fix the second driving circuit board to the intermediate assembly 1. In other words, this embodiment realizes the power transmission of the second conductive connection component 4 and the lighting control of the lamp by setting the second circuit board 29. Compared with the transmission of wires or metal parts, the second circuit board 29 can improve the contact stability with the second conductive connection component 4 and can also increase the design of lighting function, making it more practical. Moreover, in order to ensure the accurate assembly and fixation of the second circuit board 29, the first positioning insert 30 is set in the intermediate assembly 1 to assemble with the second positioning insert 31 of the second circuit board 29, making the assembly of the second circuit board 29 more accurate and stable.

[0075] The assembly structure of the first outer shell and the second outer shell is as follows:

[0076] The first outer shell is connected to the second outer shell via an intermediate assembly 1. The structure of the intermediate assembly 1 is shown in Figure 15. Limiting blocks 6 are provided on both sides of the intermediate assembly 1, and the first outer shell is provided with a limiting groove 7. The limiting blocks 6 are fitted into the limiting groove 7 to limit the intermediate assembly 1 within the first connecting cavity. The first outer shell is provided with a first connecting cavity for assembling the intermediate assembly 1, and the second outer shell is provided with a second connecting cavity for assembling the intermediate assembly 1. The intermediate assembly 1 is provided with a locking block 8, and the second outer shell is provided with a locking hole. The second outer shell is screwed to the locking hole and the locking block 8 to lock the intermediate assembly 1. Therefore, in actual assembly, the intermediate assembly 1 can be fixed to the first outer shell first. After the first and second outer shells are assembled, the second outer shell is then locked to the intermediate assembly to complete the assembly of this embodiment. That is, during production, the assembly can be carried out in modules, which helps to improve production assembly efficiency.

[0077] As shown in Figures 13 and 14, the second upper shell 17 has a first radial positioning block 21 and a second radial positioning block 22 on the side near the first upper shell 11, and the second lower shell 18 has a third radial positioning block 24 and a fourth radial positioning block 25 on the side near the second lower shell 18. The first upper shell 11 has a first positioning groove 23, and the first lower shell 12 has a second positioning groove 26. When the first shell and the second shell are assembled, the first radial positioning block 21 is inserted into the first positioning groove 23, and the third radial positioning block 24 is inserted into the second positioning groove 26. The second radial positioning block 22 is attached to the inner surface of the first upper shell 11, and the fourth radial positioning block 25 is attached to the inner surface of the first lower shell 12. In other words, by setting multiple radial positioning blocks, the accuracy of the assembly of the first shell and the second shell can be improved, the assembly process is simpler, and the production assembly efficiency can be improved.

[0078] In addition, the first connecting cavity and the second connecting cavity are assembled to form a connecting cavity, and a lamp assembly 9 is assembled in the connecting cavity, and the lamp assembly 9 is used to assemble with an external lamp.

[0079] In this embodiment, by setting a first driving mechanism and a second driving mechanism, the flexibility of the drive is increased, making the driver of this embodiment more adaptable to the use of large lamps or lamps with more functional control requirements, and thus having higher practicality.

[0080] Example 4:

[0081] The lamp connection structure provided in this embodiment, as shown in Figures 16 to 20, includes a threaded joint 031, a washer 32, a gasket 33, a lamp connector, and a locking member 311. One end of the threaded joint 031 is mounted on an external driver, the washer 32 is fixed to the external driver, the lamp connector is provided with a limiting groove 36, the gasket 33 is assembled into the limiting groove 36, the washer 32 is located above the gasket 33, the washer 32 is provided with a protrusion 37, and the gasket 33 has a rotation limiting feature. The protruding post 37 is located in the rotation limiting hole 38 and can move within the rotation limiting hole 38; the washer 32 has a first through hole 39 in the middle and the lamp connector has a second through hole 310 in the middle; the other end of the threaded joint 031 passes through the first through hole 39 and the second through hole 310 in sequence, and the threaded joint 031 is locked to the lamp connector by the locking member 311; when the lamp connector rotates, it drives the threaded joint 031 to rotate.

[0082] Specifically, washer 32 is connected to the driver of the lamp to prevent it from rotating. The lamp connector is connected to the lamp and can be rotated by rotating the lamp. The rotation of the lamp connector causes the washer 33 to rotate, and the rotation limiting hole 38 also rotates accordingly. When the protrusion 37 of washer 32 is engaged with the end of the rotation limiting hole 38, the lamp can no longer rotate, thus limiting the rotation of the lamp. Therefore, as shown in Figure 19, the lamp can rotate clockwise or counterclockwise under the restriction of the rotation limiting hole 38. The angle of rotation is determined by the rotation limiting hole 38. As shown in Figure 19, when the length of the rotation limiting hole 38 is longer, a larger angle of rotation can be achieved. The size of the rotation limiting hole 38 can be set according to the actual situation, and this embodiment does not impose any restrictions.

[0083] As shown in Figure 17, the shape of the toothed joint 031 includes a circular toothed joint 031 cap, which is installed in the driver. The portion of the toothed joint 031 located in the first through hole 39 and the second through hole 310 has the shape shown in Figure 20, with two limiting surfaces 315, so that the toothed joint 031 can be rotated when the lamp connector rotates. The first through hole 39 does not restrict the rotation of the toothed joint 031, thus avoiding affecting the fixation of the washer 32.

[0084] Figure 18 shows the structure of washer 32. Washer 32 is provided with a slot for embedding an external driver, and the outer periphery of the external driver fits against the slot wall. The external driver is also provided with a protrusion 313, which is inserted into the fixing hole 312 of washer 32 to achieve positioning between the two and maintain the fixation between washer 32 and driver, thereby keeping the protruding post 37 fixed. In this way, when the washer 33 rotates, the protruding post 37 does not rotate, ensuring that the relative position of the protruding post 37 changes within the limitation range of the rotation limiting hole 38, thus limiting the rotation angle of the lamp.

[0085] Figures 18 and 19 show the structure of the gasket 33, which has two arc-shaped rotation limiting holes 38, symmetrically arranged about the central axis of the gasket 33. To allow the user to determine whether the protrusion 37 is located at the end of the rotation limiting hole 38, this embodiment provides locking blocks 314 at both ends of the rotation limiting hole 38. Since the protrusion 37 is cylindrical, it can reach the end of the rotation limiting hole 38 through the locking blocks 314. When the user rotates the lamp, they will feel the locking contact between the protrusion 37 and the locking blocks 314, indicating that the protrusion 37 is at the end of the rotation limiting hole 38. This means the lamp's rotation has reached the limited angle and cannot be continued, or the user can choose to rotate in the opposite direction. The locking blocks 314 facilitate the user's understanding of the lamp's rotation position.

[0086] Figures 17 and 18 show the structure of the lamp connector. The lamp connector includes a connecting block 34 and a fixing block 35. The fixing block 35 has an assembly hole 316 on its outer periphery. The connecting block 34 is provided with an assembly block 317 that is assembled into the assembly hole 316. The second through hole 310 is located in the fixing block 35. After the threaded joint 031 passes through the second through hole 310, the threaded joint 031 is locked to the lamp connector by the locking member 311. The tightness of the lamp rotation can be adjusted by adjusting the locking degree of the locking member 311, which provides high flexibility.

[0087] This embodiment uses the fit between washer 32 and shim 33 to restrict the rotation of the lamp, thereby avoiding unstable installation of the lamp due to repeated rotation, making it more practical.
