Description

Technical Field

[0001] This application belongs to the field of lighting design technology, and specifically relates to a lighting fixture. Background Technology

[0002] As people's quality of life improves, the quality of products used in daily life also improves accordingly. In the field of lighting technology, the lighting effect of lighting fixtures has also received attention.

[0003] In related technologies, lighting fixtures typically include a mounting base and a lamp body. The mounting base is installed on a wall, and the lamp body is rotatably connected to the mounting base, allowing the lamp body to rotate relative to the mounting base and adjust the light output direction. Furthermore, to improve the user's feel when rotating the lamp body and increase the damping force during rotation, threaded fasteners are used to penetrate the lamp body housing and the mounting base, and nuts are used to lock the threaded fasteners. In other words, the threaded fastener acts as a pivot, with the lamp body rotating around it relative to the mounting base. However, due to the locking effect of the nut, the nut prevents the threaded fastener from rotating with the lamp body. That is, the nut applies a damping force to the threaded fastener, which simultaneously bears the rotational driving force of the lamp body and the obstructing force of the nut. This makes the threaded fastener prone to fatigue and breakage, thus affecting the service life of the lighting fixture. Summary of the Invention

[0004] The purpose of this application is to provide a lighting fixture that can solve the problem of short service life of lighting fixtures in related technologies.

[0005] This application provides a lighting fixture, including a mounting base, a lamp body, a first rotating shaft, and a rotating bearing. The first end of the first rotating shaft is connected to the lamp body. The mounting base has a first opening through which the second end of the first rotating shaft passes. The rotating bearing is disposed inside the mounting base and is sleeved on the outside of the first rotating shaft.

[0006] The rotating bearing includes a first rotating part and a second rotating part that are rotatably connected. The first rotating part is connected to the mounting base, and the second rotating part is connected to the second end of the first rotating shaft. The lamp body, the first rotating shaft, and the second rotating part can all rotate relative to the mounting base about the axis of the first rotating shaft.

[0007] In this embodiment, a rotating bearing is added to the lighting fixture. The first rotating part of the rotating bearing is connected to the mounting base, and the second rotating part of the rotating bearing is connected to the first rotating shaft. That is, the second end of the first rotating shaft is connected to the mounting base through the rotating bearing. Since the first and second rotating parts can rotate relative to each other, the second end of the first rotating shaft can rotate relative to the mounting base during the rotation of the lamp body around the first rotating shaft. Even if the second end of the first rotating shaft needs to withstand a resisting force to improve the damping feel, the resisting force will ultimately be applied to the first rotating part through the second rotating part, affecting the relative rotation of the first and second rotating parts, but not affecting the rotation of the first rotating shaft. Therefore, the second end of the first rotating shaft is not affected by the resisting force, and the first rotating shaft rotates with the lamp body as a whole under the driving force of the lamp body. With this configuration, the first rotating shaft does not need to directly bear both the rotational driving force and the resisting force from the lamp body at the same time, and can smoothly follow the rotation of the lamp body, which is beneficial to improving the fatigue resistance of the first rotating shaft and extending its service life.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0031] The lighting fixtures provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0032] Please refer to Figures 1-10 The lighting fixture disclosed in this application includes a mounting base 100, a lamp body 200, a first rotating shaft 300, and a rotating bearing 400. The mounting base 100 serves as the mounting foundation for the lamp body 200, the first rotating shaft 300, and the rotating bearing 400. Optionally, the mounting base 100 can be a ceiling-mounted box for installation on the top wall of a wall. The lamp body 200 is connected to the mounting base 100 via the first rotating shaft 300, and the lamp body 200 can rotate relative to the mounting base 100 around the axis of the first rotating shaft 300. Optionally, the lamp body 200 can be a downlight. The rotating bearing 400 is used to reduce the friction between the first rotating shaft 300 and the mounting base 100 during rotation.

[0033] The first end of the first rotating shaft 300 is connected to the lamp body 200. Optionally, the first end of the first rotating shaft 300 can be fixedly connected to the lamp body 200 or rotatably connected, such as... Figure 5 As shown, the mounting base 100 has a first opening 110 through which the second end of the first rotating shaft 300 passes. A rotating bearing 400 is disposed within the mounting base 100 and is sleeved on the outside of the first rotating shaft 300. Figures 2-4 As shown, the rotating bearing 400 includes a first rotating part 410 and a second rotating part 420 rotatably connected. The first rotating part 410 is connected to the mounting base 100, and the second rotating part 420 is connected to the second end of the first rotating shaft 300. The lamp body 200, the first rotating shaft 300, and the second rotating part 420 can all rotate relative to the mounting base 100 around the axis of the first rotating shaft 300. Optionally, the first rotating part 410 and the second rotating part 420 can be arranged sequentially along the direction of the axis of the first rotating shaft 300. The first rotating part 410 can be fixedly connected to the mounting base 100 by means of threaded fasteners (such as bolts). The second rotating part 420 can be directly connected to the second end of the first rotating shaft 300 by means of welding or other methods, or indirectly connected by other components.

[0034] In this embodiment, a rotating bearing 400 is added to the lighting fixture. The first rotating part 410 of the rotating bearing 400 is connected to the mounting base 100, and the second rotating part 420 of the rotating bearing 400 is connected to the first rotating shaft 300. That is, the second end of the first rotating shaft 300 is connected to the mounting base 100 through the rotating bearing 400. Since the first rotating part 410 and the second rotating part 420 can rotate relative to each other, during the rotation of the lamp body 200 around the first rotating shaft 300, the second end of the first rotating shaft 300 can rotate relative to the mounting base 100. Even if the second end of the first rotating shaft 300 needs to withstand a resisting force to improve the damping feel, the resisting force will eventually be absorbed by the second rotating shaft.

[0035] The second rotating part 420 applies force to the first rotating part 410, affecting the relative rotation of the first rotating part 410 and the second rotating part 420, but not affecting the rotation of the first rotating shaft 300. Therefore, the second end of the first rotating shaft 300 is not affected by the obstructing force, and the first rotating shaft 300 is driven by the lamp body 200 and rotates as a whole with the lamp body 200.

[0036] With this configuration, the first rotating shaft 300 does not need to directly bear the rotational driving force and the resisting force from the lamp body 200 at the same time, and can smoothly follow the rotation of the lamp body 200. This helps to improve the fatigue resistance of the first rotating shaft 300 and extend its service life.

[0037] In one optional embodiment, the lighting fixture further includes a pressing member. The first rotating part 410, the second rotating part 420, and the pressing member are arranged sequentially along the direction of the first rotating shaft 300, and the pressing member is fixedly connected to the first rotating shaft 300 by a non-removable method such as welding. The pressing member can press the first rotating part 410 and the second rotating part 420. In another embodiment, the lighting fixture further includes a first locking member 510. The first rotating part 410, the second rotating part 420, and the first locking member 510 are arranged sequentially along the direction of the first rotating shaft 300, and the first locking member 510 is threadedly engaged with the second end of the first rotating shaft 300 to press the first rotating part 410 and the second rotating part 420. In this embodiment, by pressing the first rotating part 410 and the second rotating part 420 with the first locking member 510, the damping force between the first rotating part 410 and the second rotating part 420 can be increased, improving the feel of the user when rotating the lamp body 200. Moreover, the relative position of the first locking member 510 and the first rotating shaft 300 can be adjusted by the thread, thereby adjusting the damping force of the first locking member 510 on the first rotating part 410 and the second rotating part 420, so that the user can adjust the damping feel as needed.

[0038] In an optional embodiment, the lighting fixture further includes a power supply device 900 and electrical connection wires, such as... Figure 2As shown, the power supply device 900 is disposed within the mounting base 100. The first rotating shaft 300 has a first wire-passing hole in its extending direction, and the rotating bearing 400 has a second wire-passing hole along the direction of the first rotating shaft 300. The electrical connection wire passes through the first and second wire-passing holes, with its first end electrically connected to the power supply device 900 and its second end electrically connected to the lamp body 200. Thus, the electrical connection between the lamp body 200 and the power supply device 900 is achieved through the electrical connection wire, enabling the lamp body 200 to emit light normally.

[0039] In optional embodiments, such as Figures 2-4 As shown, the lighting fixture also includes a first fixing seat 520 and a second fixing seat 530 disposed within the mounting base 100. The first fixing seat 520 is connected to the mounting base 100, and the second fixing seat 530 is connected to the second end of the first rotating shaft 300 and can rotate with the first rotating shaft 300. Optionally, the first fixing seat 520 and the mounting base 100 can be fixedly connected by a threaded fastener (such as a bolt). The second fixing seat 530 passes through the second end of the first rotating shaft 300, and the second fixing seat 530 can be fixedly connected to the second rotating part 420 by a threaded fastener (such as a bolt). The first locking member 510 presses the second fixing seat 530, thereby pressing the first rotating part 410 and the second rotating part 420. The first fixing seat 520 is provided with a first limiting part 521, and the second fixing seat 530 is provided with a second limiting part 531. The first limiting part 521 and the second limiting part 531 are engaged in a limiting fit in the rotation direction of the first rotating shaft 300. In this embodiment, the first limiting part 521 and the second limiting part 531 are used to limit the rotation angle of the first rotating shaft 300 relative to the mounting base 100. When the first rotating shaft 300 is close to the wall, the rotation amplitude of the first rotating shaft 300 is prevented from being too large and damaging the wall. Also, when the first rotating shaft 300 is used to pass electrical connection wires, the electrical connection wires are prevented from being jammed due to excessive rotation angle, which would lead to the inability to transmit power.

[0040] Optionally, the first limiting part 521 can be a limiting post, and the second limiting part 531 can be a limiting protrusion. The limiting protrusion can rotate relative to the limiting post, and the limiting protrusion and the limiting post are engaged in a limiting engagement in a first rotation direction and a second rotation direction, wherein the first rotation direction and the second rotation direction are opposite. Optionally, due to the limiting engagement between the limiting protrusion and the limiting post, the rotation angle of the first rotating shaft 300 relative to the mounting base 100 can be 339°.

[0041] Of course, in other embodiments, the lighting fixture may not have the first limiting part 521 and the second limiting part 531, that is, the rotation angle of the first fixing base 520 relative to the first mounting base 100 is 360°.

[0042] In optional embodiments, such as Figure 4 As shown, the second end of the first rotating shaft 300 is provided with a concave surface, and the second fixed seat 530 is provided with a third opening 532 that cooperates with the second end of the first rotating shaft 300. The user drives the first rotating shaft 300 to rotate by rotating the first locking member 510. The first rotating shaft 300 drives the second fixed seat 530 to rotate through the cooperation structure of the third opening 532 and the concave surface. In turn, the second fixed seat 530 drives the second rotating part 420 to rotate. At the same time, the first locking member 510 is displaced in the direction of the axis of the first rotating shaft 300. Therefore, the first locking member 510 presses the second fixed seat 530, and the second fixed seat 530 presses the second rotating part 420 and the first rotating part 410.

[0043] Optionally, the first fixed base 520 is provided with at least two bosses 522, and the first rotating part 410 is provided with a groove that cooperates with the bosses 522. The grooves correspond one-to-one with the bosses 522. In this way, the bosses 522 are used to position the first rotating part 410 relative to the first fixed base 520, ensuring that the first wire hole of the first rotating shaft 300 and the second wire hole of the rotating bearing 400 are connected, and ensuring that the installation position of the rotating bearing 400 is accurate.

[0044] In one optional embodiment, the lighting fixture further includes a second rotating shaft 610. The lamp body 200 includes a housing 210, which is connected to the first rotating shaft 300 via the second rotating shaft 610, allowing the lamp body 200 to rotate relative to the first rotating shaft 300 about the second rotating shaft 610, with the axis of the second rotating shaft 610 intersecting the axis of the first rotating shaft 300. Optionally, the axis of the second rotating shaft 610 is perpendicular to the axis of the first rotating shaft 300. The housing 210 may have a cylindrical groove, through which the second rotating shaft 610 passes and extends into the cylindrical groove, allowing the second rotating shaft 610 to rotate within the groove, thus enabling the lamp body 200 to rotate relative to the first rotating shaft 300.

[0045] In another embodiment, combined Figures 5-7 As shown, the first rotating shaft 300 abuts against the second rotating shaft 610, meaning the second rotating shaft 610 does not completely penetrate the first rotating shaft 300. The lighting fixture also includes an adjusting member 620, which is connected to the housing 210 and abuts against the second rotating shaft 610 to adjust the abutting force of the second rotating shaft 610 against the first rotating shaft 300. Thus, the greater the abutting force of the adjusting member 620 against the second rotating shaft 610, the greater the abutting force of the second rotating shaft 610 against the first rotating shaft 300. Therefore, during the rotation of the lamp body 200 around the second rotating shaft 610 relative to the first rotating shaft 300, the damping force is greater, which helps improve the damping feel during rotation. Optionally, the adjusting member 620 can be an adjusting screw.

[0046] In one optional embodiment, the housing 210 is provided with a slot 211 into which the first end of the first rotating shaft 300 extends, the housing 210 is provided with a first opening 212, and the first rotating shaft 300 is provided with a third opening 310. The first opening 212, the third opening 310 and the slot 211 are sequentially connected on the axis of the second rotating shaft 610. One end of the second rotating shaft 610 passes through the first opening 212 and the third opening 310 in sequence, that is, a part of the second rotating shaft 610 extends into the interior of the first rotating shaft 300. The adjusting member 620 is located on the same side of the first rotating shaft 300 as the second rotating shaft 610, and the adjusting member 620 is located on the side of the second rotating shaft 610 facing away from the first rotating shaft 300. The adjusting member 620 presses the second rotating shaft 610 so that the second rotating shaft 610 abuts against the first rotating shaft 300.

[0047] In another embodiment, the housing 210 is further provided with a second opening 213, and the first rotating shaft 300 is further provided with a fourth opening 320. The first opening 212, the third opening 310, the slot 211, the fourth opening 320, and the second opening 213 are sequentially connected in the direction of the axis of the second rotating shaft 610. The first end of the adjusting member 620 passes through the second opening 213 and the fourth opening 320 in sequence and abuts against the second rotating shaft 610. That is, the adjusting member 620 is disposed on the side of the second rotating shaft 610 facing the first rotating shaft 300. With this embodiment, the adjusting member 620 can not only adjust the abutting force of the second rotating shaft 610 against the first rotating shaft 300, but also provide a supporting force for the rotation of the lamp body 200 around the second rotating shaft 610 relative to the first rotating shaft 300. That is, the adjusting member 620 and the second rotating shaft 610 jointly provide rotational support, which is beneficial for the stable rotation of the lamp body 200 around the second rotating shaft 610 relative to the first rotating shaft 300.

[0048] Optionally, such as Figure 7 As shown, the first part of the second rotating shaft 610 extends into the interior of the first rotating shaft 300 through the first opening 212 and the third opening 310. The second part of the second rotating shaft 610 is rotatably engaged with the housing 210. The adjusting member 620 may include an adjusting screw. The first part of the second rotating shaft 610 is provided with a threaded hole, and one end of the adjusting screw can extend into the threaded hole and be threadedly engaged with the second rotating shaft 610. In this way, the second rotating shaft 610 and the adjusting member 620 rotate relative to the lamp body 200 around the axis of the second rotating shaft 610, following the first rotating shaft 300. Furthermore, by changing the length of the adjusting screw extending into the threaded hole, the abutting force of the second part of the second rotating shaft 610 against the first rotating shaft 300 can be adjusted.

[0049] In an optional embodiment, the lighting fixture may further include a washer 630, with one end of an adjusting screw passing through the washer 630, the second opening 213, and the fourth opening 320 in sequence. The nut of the adjusting screw presses the washer 630 against the outer surface of the housing 210. There is a certain friction between the washer 630 and the housing 210, which increases the damping force during the rotation of the lamp body 200 around the second pivot 610 relative to the first pivot 300, which is beneficial to further improve the feel during the rotation process.

[0050] In an optional embodiment, the adjusting member 620 may include an adjusting screw, and the lighting fixture may also include a cylindrical body 640. The cylindrical body 640 is located inside the first rotating shaft 300 and is sleeved on the outside of the adjusting member 620. The cylindrical body 640 separates the electrical connection wire passing through the first rotating shaft 300 from the adjusting member 620, so as to avoid the electrical connection wire from directly contacting the adjusting screw and causing the thread to scratch the electrical connection wire.

[0051] In one optional embodiment, the lamp body 200 can rotate 360° relative to the first axis of rotation about the second axis of rotation 610. In another embodiment, refer to... Figure 6 As shown, in the direction of rotation around the second rotating shaft 610, the housing 210 is in a limiting engagement with the first rotating shaft 300. Specifically, when the lamp body 200 rotates relative to the first rotating shaft 300 around the axis of the second rotating shaft 610 to a preset position, the housing 210 and the first rotating shaft 300 make limiting contact. Optionally, the rotation angle range of the lamp body 200 relative to the first rotating shaft 300 is 94°. This embodiment limits the rotation range of the second rotating shaft 610 and the lamp body 200 relative to the first rotating shaft 300, preventing the electrical connection wires from breaking due to excessive bending angles, thus avoiding the problem of power transmission failure.

[0052] In the scheme of this application, such as Figure 8 As shown, the lighting fixture also includes a backlight assembly 700, which includes a ring circuit board 710 and a plurality of LED beads 720. The ring circuit board 710 is disposed on the outer periphery of the mounting base 100, and the plurality of LED beads 720 are spaced apart on the side of the ring circuit board 710 facing away from the lamp body 200. Optionally, the ring circuit board 710 is electrically connected to a power supply device 900 disposed in the mounting base 100, thereby enabling the ring circuit board 710 to supply power to each LED bead 720, so that the LED beads 720 emit light. In this embodiment, the plurality of LED beads 720 emit light from the side of the ring circuit board 710 facing away from the lamp body 200, thereby achieving backlighting, assisting the lamp body 200 in illumination, and improving the lighting effect and lighting atmosphere. Of course, in other embodiments, the lighting fixture may rely solely on the lamp body 200 for illumination, that is, the lighting fixture may not include a backlight assembly 700.

[0053] In one optional embodiment, the annular circuit board 710 can be directly disposed on the outside of the mounting base 100; or, in conjunction with Figures 8-10 As shown, the backlight assembly 700 also includes a panel 730 and an annular light guide plate 740. The panel 730 is connected to the mounting base 100 and has a second opening 731 through which the first rotating shaft 300 passes. The annular light guide plate 740 is sleeved on the outside of the mounting base 100 and is connected to the panel 730, so that the annular light guide plate 740 and the panel 730 together form a receiving space for accommodating the annular circuit board 710 and the LED beads 720. Specifically, the panel 730 is located on the side of the annular circuit board 710 facing the lamp body 200, and the annular light guide plate 740 is located on the side of the annular circuit board 710 facing away from the lamp body 200. The edge of the panel 730 is connected to the edge of the annular light guide plate 740. In this embodiment, the annular circuit board 710 and the LED beads 720 are surrounded and protected by the panel 730 and the annular light guide plate 740, preventing the annular circuit board 710 and the LED beads 720 from being exposed. Moreover, the annular light guide plate 740 can diffuse the light from multiple LED beads 720 to achieve uniform light output.

[0054] Optionally, the annular circuit board 710 is disposed on the panel 730, which can be a heat dissipation structure, thereby dissipating heat from the annular circuit board 710 through the panel 730. Optionally, the panel 730 can be made of aluminum.

[0055] In one alternative embodiment, such as Figure 9 As shown, one of the annular light guide plate 740 and the annular circuit board 710 is provided with at least one first positioning hole 711, and the other is provided with at least one first positioning post 741, the first positioning post 741 being positioned and engaged with the first positioning hole 711; and / or, as shown Figure 10 As shown, one of the annular light guide plate 740 and the mounting base 100 is provided with at least one second positioning hole 120, and the other is provided with at least one second positioning post 742. The second positioning post 742 and the second positioning hole 120 are positioned and engaged in a one-to-one manner. In this embodiment, the relative position of the annular light guide plate 740 and the annular circuit board 710 is restricted by the positioning engagement of the first positioning post 741 and the first positioning hole 711, facilitating the connection between the annular light guide plate 740 and the annular circuit board 710. At the same time, the relative position of the annular light guide plate 740 and the mounting base 100 is restricted by the positioning engagement of the second positioning post 742 and the second positioning hole 120, facilitating the connection between the annular light guide plate 740 and the mounting base 100, ensuring the relative fixation of the mounting base 100, the annular light guide plate 740, and the annular circuit board 710, so as to achieve accurate connection.

[0056] Of course, in other embodiments, the annular light guide plate 740 and the annular circuit board 710 can be positioned and engaged without the first positioning hole 711 and the first positioning post 741, and the two can be directly connected by welding or other means; similarly, the annular light guide plate 740 and the mounting base 100 can also be positioned and engaged without the second positioning hole 120 and the second positioning post 742, and the two can be directly connected by welding or other means.

[0057] In one optional embodiment, the mounting base 100 and the panel 730 can be directly fixedly connected to the first rotating shaft 300 by means of welding or other methods. In another embodiment, such as Figure 5 As shown, the lighting fixture also includes a sleeve 810 and a second locking member 820. The sleeve 810 includes a connected sleeve 811 and a third limiting part 812. The sleeve 811 is sleeved on the outside of the first rotating shaft 300, and the panel 730 and the mounting base 100 are sleeved on the outside of the sleeve 811. The third limiting part 812 is in a limiting engagement with the panel 730. The second locking member 820 is threadedly engaged with the sleeve 811. Thus, the sleeve 810 can prevent the panel 730 and the mounting base 100 from moving along the direction of the first rotating shaft 300, and can also cooperate with the second locking member 820 to fix the panel 730 and the mounting base 100 between the third limiting part 812 and the second locking member 820, thereby achieving a fixed connection between the panel 730, the mounting base 100 and the first rotating shaft 300. Furthermore, by using the sleeve 810 and the second locking member 820, the connection area between the mounting base 100 and the first rotating shaft 300 is increased, and the connection area between the panel 730 and the first rotating shaft 300 is also increased, which helps to improve the connection stability.

[0058] In one optional embodiment, the power supply device 900 is located at the center of the mounting base 100, and the first rotating shaft 300 is offset from the center of the mounting base 100. That is, the first rotating shaft 300 is also offset from the center of the panel 730 and the annular light guide plate 740. Thus, when the mounting base 100 and the panel 730 are connected at the first rotating shaft 300, the position of the panel 730 away from the first rotating shaft 300 is easily caused to lift up, which makes the connection between the panel 730 and the annular light guide plate 740 not tight enough.

[0059] In another embodiment, such as Figure 9 As shown, the annular light guide plate 740 is provided with an overflow groove 743. The annular light guide plate 740 is connected to the panel 730 by a connecting adhesive disposed in the overflow groove 743. (Refer to...) Figure 2As shown, the mounting base 100 has a center line A perpendicular to the first rotating shaft 300. An adhesive overflow groove 743 and a sleeve 810 are sequentially arranged in the direction of center line A, with the adhesive overflow groove 743 and the sleeve 810 located on either side of the center of the mounting base 100. In this embodiment, the adhesive in the adhesive overflow groove 743 further connects the annular light guide plate 740 and the panel 730 away from the first rotating shaft 300, preventing the panel 730 from warping and causing a loose connection between the panel 730 and the annular light guide plate 740, thus improving connection stability. Optionally, the mounting base 100 has a circular structure, with the center line A perpendicular to the first rotating shaft 300 passing through the center of the mounting base 100; therefore, the center of the mounting base 100 is its circular center.
