[0034] The following describes in detail embodiments of the present invention, which are illustrative only with reference to the accompanying drawings.

[0035] Reference below Figures 1-8 The lighting lamp 100 according to an embodiment of the present invention can flexibly adjust the lighting range and lighting angle of the light-emitting element 2 according to usage requirements, avoiding the problem of only being able to obtain a suitable lighting effect by moving the entire lighting lamp 100, thereby improving the flexibility and diversity of adjusting the lighting position of the light-emitting element 2. For example, the lighting lamp 100 can be a desk lamp and can be applied to a study table, but is not limited thereto.

[0036] Combine Figures 1-8 As shown, a lighting fixture 100 according to an embodiment of the first aspect of the present invention includes a bracket 1, a plurality of light-emitting elements 2, and a synchronization mechanism 3. The bracket 1 primarily serves as a load-bearing structural member, supporting the plurality of light-emitting elements 2. The light-emitting elements 2 provide illumination, thereby satisfying the user's lighting needs. The synchronization mechanism 3 drives the plurality of light-emitting elements 2 to move synchronously, facilitating simultaneous adjustment of the lighting positions of the plurality of light-emitting elements 2, thereby improving operational convenience.

[0037] Specifically, multiple light-emitting parts 2 can be rotatably arranged on the bracket 1, and the multiple light-emitting parts 2 are arranged at intervals along the circumference of the bracket 1, the synchronization mechanism 3 is arranged between the multiple light-emitting parts 2, and the synchronization mechanism 3 is respectively connected to the multiple light-emitting parts 2 to drive the multiple light-emitting parts 2 to rotate synchronously under the action of external force.

[0038] Specifically, multiple light-emitting parts 2 can rotate along the circumference of the bracket 1, and multiple light-emitting parts 2 are respectively connected through the synchronization mechanism 3. This makes it convenient for the user to apply force to one of the light-emitting parts 2, and the light-emitting part 2 drives the remaining light-emitting parts 2 to rotate simultaneously through the synchronization mechanism 3, thereby achieving the synchronous rotation adjustment effect of multiple light-emitting parts 2.

[0039] For example, when a user needs a larger lighting range, the user can rotate multiple light-emitting elements 2 to positions with larger spacing angles to obtain a larger lighting range; for another example, when a user needs stronger lighting brightness, the user can rotate multiple light-emitting elements 2 to positions with smaller spacing angles to obtain stronger light brightness in a specific area; for another example, when a user needs to avoid environmental shadows in a certain direction during lighting work, the user can adjust the lighting position of the light-emitting element 2 to adjust the illumination angle of the light-emitting element 2 to reduce the environmental shadows in the lighting area. In summary, by flexibly adjusting the different lighting positions of multiple light-emitting elements 2, the user's usage needs in different lighting usage scenarios can be met, thereby effectively improving the flexibility and diversity of the lighting effect, and thus improving the user's usage experience.

[0040] Moreover, compared with traditional lighting lamps, the lighting lamp 100 in this case only needs to adjust the rotation position of the light-emitting component 2 separately to achieve the need to adjust the lighting angle. This can avoid the problem that the user needs to move the entire lighting lamp 100 to obtain a more suitable lighting angle, thereby improving the user's convenience in adjusting the lighting angle and further improving the user experience.

[0041] Therefore, by setting up the lighting lamp 100, the lighting range and lighting angle of the light-emitting component 2 can be flexibly adjusted according to usage requirements, avoiding the problem that the user can only obtain a suitable lighting effect by moving the position of the entire lighting lamp 100, thereby improving the flexibility and diversity of adjusting the lighting position of the light-emitting component 2, and further improving the user's operation convenience and usage experience.

[0042] According to some optional embodiments of the present invention, combined with Figure 6 and Figure 7 As shown, the bracket 1 is provided with a first rotating part 11, and the light-emitting part 2 is provided with a second rotating part 21, and the second rotating part 21 can be rotatably set on the first rotating part 11; the synchronization mechanism 3 includes a plurality of transmission parts 31, and the plurality of transmission parts 31 correspond one-to-one to the plurality of light-emitting parts 2, and the transmission parts 31 are provided on the second rotating part 21, and the plurality of transmission parts 31 transmit and cooperate with each other.

[0043] Among them, the second rotating part 21 on the light-emitting member 2 can be rotatably arranged on the first rotating part 11 of the bracket 1, so that the light-emitting member 2 can be easily rotated relative to the bracket 1; multiple transmission members 31 correspond to multiple light-emitting members 2 one by one, and the transmission members 31 are arranged on the second rotating part 21. When one of the light-emitting members 2 rotates under the action of an external force, the transmission member 31 connected to the light-emitting member 2 also rotates. At this time, the transmission member 31 transmits the driving force to the remaining transmission members 31 connected to it, and the remaining transmission members 31 drive the corresponding light-emitting members 2 to rotate, thereby smoothly achieving the effect of synchronous rotation of multiple light-emitting members 2 relative to the bracket 1. The synchronization mechanism 3 set in this way has a good synchronization effect, a simple structure, and is easy to install.

[0044] Specifically, combined Figure 6 and Figure 7 As shown, the first rotating part 11 is configured as a pivot shaft 111 , the second rotating part 21 is configured as a sleeve 211 , the sleeve 211 is sleeved on the pivot shaft 111 , the transmission member 31 is sleeved on the sleeve 211 , and the transmission member 31 rotates synchronously with the sleeve 211 .

[0045] It is understood that the pivot shaft 111, as the primary rotational support structure, ensures the stability of the light-emitting element 2 during rotation. The shaft sleeve 211 is mounted on the pivot shaft 111 and can rotate about the pivot shaft 111. The transmission member 31 is mounted on the outside of the shaft sleeve 211 and rotates synchronously with the shaft sleeve 211. This facilitates adjustment of the light-emitting position of the light-emitting element 2 and also facilitates synchronous adjustment of the lighting angles of the remaining light-emitting elements 2, thereby improving the practicality and convenience of the lighting lamp 100. Furthermore, the shaft sleeve 211 configured in this manner can cooperate with both the pivot shaft 111 and the transmission member 31, achieving multi-functionality and simplifying the structure of the lighting lamp 100. Furthermore, the transmission member 31 is simple and convenient to install and can achieve better synchronization with the shaft sleeve 211.

[0046] Further, combined with Figure 6 and Figure 7 As shown, the outer periphery of the sleeve 211 is provided with a limiting protrusion 212 and one of the limiting grooves, and the inner periphery of the transmission member 31 is provided with the other of the limiting protrusion 212 and the limiting groove, and the limiting protrusion 212 and the limiting groove are matched in the circumferential upper limit of the sleeve 211.

[0047] For example, a limiting protrusion 212 is provided on the outer periphery of the sleeve 211, and a limiting groove is provided on the inner periphery of the transmission member 31. The limiting protrusion 212 and the limiting groove cooperate with each other in the circumferential upper limit of the sleeve 211, so that the sleeve 211 can smoothly transmit torque and power to the transmission member 31, thereby ensuring the movement synchronization and relative position stability between the sleeve 211 and the transmission member 31.

[0048] Specifically, combined Figure 5-Figure 7 As shown, the light emitting element 2 includes a lamp housing 22 , which is provided with an opening 221 . The second rotating portion 21 is provided in the lamp housing 22 , and a portion of the transmission element 31 extends out of the lamp housing 22 through the opening 221 .

[0049] It can be understood that the lamp housing 22 mainly serves as a structural component of the outer contour of the lighting lamp 100, which can be used to protect internal parts and provide installation and fixing conditions for internal parts; an opening 221 is provided on the lamp housing 22, so that part of the transmission part 31 can pass through the opening 221 to extend to the outside of the lamp housing 22, avoiding the problem of the lamp housing 22 forming an obstruction between the transmission part 31, thereby smoothly achieving the effect of transmission connection with the remaining transmission parts 31, thereby improving its design rationality.

[0050] Further, combined with Figure 5-Figure 7 As shown, the lamp housing 22 includes a shell 222 and a cover 223. The outer periphery of the shell 222 is formed with an opening 221, and one side is formed with an opening 2221. The second rotating part 21 is arranged in the shell 222, and the second rotating part 21 is connected to the shell 222. The cover 223 is arranged at the opening 2221.

[0051] That is to say, an opening 2221 is formed on one side of the shell 222, which makes it convenient for the operator to assemble and disassemble the parts inside the shell 222 through the opening 2221, thereby improving the convenience of maintenance and replacement; the second rotating part 21 is connected to the shell 222, which can form a structural protection effect for the second rotating part 21, and the cover body 223 is covered at the opening 2221 of the shell 222, so that it can form a more comprehensive protection effect on the internal parts together with the shell 222, thereby ensuring the safety of the light-emitting component 2.

[0052] In addition, since the cover plate is connected to the shell 222 , the weight and spatial mode of the shell 222 can be increased, thereby improving the structural strength and bending-torsional rigidity of each other, and further improving the structural reliability of the shell 222 .

[0053] According to some optional embodiments of the present invention, combined with Figure 2 、 Figure 4 and Figure 6 As shown, the bracket 1 is provided with a limiting portion 12 , and when the light-emitting component 2 rotates to a specified position, the light-emitting component 2 is limitedly engaged with the limiting portion 12 .

[0054] For example, when the light-emitting component 2 rotates to a certain angle relative to the bracket 1, the limiting portion 12 on the bracket 1 forms a limiting cooperation relationship with the light-emitting component 2, thereby facilitating the control of the rotation angle of multiple light-emitting components 2 relative to the bracket 1, and preventing the risk of multiple light-emitting components 2 interfering with and colliding with adjacent structures due to excessive rotation angles, thereby improving the rationality of their layout.

[0055] Specifically, combined Figure 4 、 Figure 6 and Figure 7 As shown, transmission member 31 is a gear. Gears provide stable power transmission (due to a fixed transmission ratio), thereby reducing shaking and instability of the light-emitting element 2 during rotation. They also enable more precise angle adjustment, ensuring that the light is precisely illuminated at the desired location. For example, users can precisely adjust the lighting position of the light-emitting element 2 according to their needs, ensuring that the target area is adequately illuminated while reducing eye fatigue.

[0056] Optionally, the gear transmission can also be locked after the angle is adjusted by designing a self-locking mechanism or cooperating with other locking devices (such as a ratchet) to prevent accidental rotation.

[0057] According to some optional embodiments of the present invention, combined with Figure 1 、 Figure 3-Figure 6 and Figure 8 As shown, the lighting lamp 100 also includes a fixed base 4, a first rotating frame 5 and a second rotating frame 6. The fixed base 4 is used to connect to the mounting structure. One end of the first rotating frame 5 can be rotatably connected to the bracket 1, and the other end of the first rotating frame 5 can be rotatably connected to the second rotating frame 6. The second rotating frame 6 can be rotatably connected to the fixed base 4. The rotation axes of the two ends of the first rotating frame 5 and the rotation axis of the second rotating frame 6 have an angle.

[0058] Among them, the two ends of the first rotating frame 5 can be rotatably connected to the bracket 1 and the second rotating frame 6 respectively, so that the user can adjust the lighting position of the bracket 1 relative to the first rotating frame 5 and the lighting position of the first rotating frame 5 relative to the second rotating frame 6 according to lighting needs, and the second rotating frame 6 can be rotatably connected to the fixed seat 4, so that the user can adjust the lighting position of the second rotating frame 6 relative to the fixed seat 4 according to lighting needs, so that the position that meets the user's lighting needs can be adjusted through the above-mentioned multiple rotation adjustment methods, thereby improving the lighting position diversity and flexibility of the lighting lamp 100.

[0059] Furthermore, the rotation axes at both ends of the first rotating frame 5 form an angle with the rotation axis of the second rotating frame 6. For example, the first rotating frame 5 can rotate in a vertical plane, while the second rotating frame 6 can rotate in a horizontal plane. This combination of two rotation ranges can cover more lighting positions in the space, thereby improving the comprehensive coverage of lighting positions.

[0060] Specifically, combined Figure 5 and Figure 6As shown, the first rotating frame 5 includes a connecting rod 51, a first rotating shaft 52 and a second rotating shaft 53. The connecting rod 51 is in the shape of a long strip. The first rotating shaft 52 is connected to the bracket 1. The first rotating shaft 52 can be rotatably connected to one end of the connecting rod 51. The second rotating shaft 53 is connected to the second rotating frame 6. The second rotating shaft 53 can be rotatably connected to the other end of the connecting rod 51.

[0061] It can be understood that the two ends of the connecting rod 51 can be rotatably connected to the first rotating shaft 52 and the second rotating shaft 53 respectively. The connecting rod 51 is constructed in a long strip shape, which can increase the adjustment range of the first rotating frame 5, and the first rotating shaft 52 and the second rotating shaft 53 are respectively connected to the first rotating frame 5 and the second rotating frame 6 at the same time, so that the connecting rod 51 can be easily rotated relative to the bracket 1 and the second rotating frame 6 respectively, thereby effectively improving the position adjustment range of the lighting lamp 100, thereby meeting the lighting usage needs of users in different scenarios.

[0062] Furthermore, combined with 5, Figure 6 and Figure 8 As shown, the fixing seat 4 is provided with a clamping groove 41 on the side away from the second rotating frame 6, and a threaded hole is formed on the side of the clamping groove 41; the fixing seat 4 includes an adjusting member 42 and a clamping member 43, the outer periphery of the adjusting member 42 is provided with a threaded portion 421, the adjusting member 42 is passed through a threaded hole, the threaded portion 421 is threadedly engaged with the threaded hole, and the clamping member 43 is connected to one end of the adjusting member 42 located in the clamping groove 41, so as to selectively move away from and close to the side of the clamping groove 41 where the threaded hole is formed under the action of the adjusting member 42.

[0063] That is to say, the threaded hole on the side of the clamping groove 41 and the threaded portion 421 on the outer periphery of the adjusting member 42 are threadedly matched. As the threaded portion 421 on the adjusting member 42 continues to extend into the clamping groove 41, the clamping member 43 connected to the adjusting member 42 also achieves the effect of moving in the clamping groove 41 toward the side with the threaded hole away from the clamping groove 41. In this way, as the adjusting member 42 extends into the clamping groove 41, the width of the interval between the clamping member 43 and the side with the threaded hole away from the clamping groove 41 gradually decreases, thereby adapting to the thickness of the required clamping structure, thereby improving the clamping adaptability of the fixing seat 4 to different clamping structures.

[0064] In addition, the thread can better withstand the load force from the axial direction, and the thread fit is self-locking, which can ensure that the adjusting part 42 can smoothly and stably adjust the width of the gap between the clamping part 43 and the side away from the threaded hole on the clamping groove 41. It can also prevent the risk of the adjusting part 42 retreating during normal fixing, thereby maintaining the fixing reliability.
