Description

Technical Field

[0001] This application belongs to the field of lighting equipment technology, and in particular relates to a lamp holder and lighting device. Background Technology

[0002] In the process of continuous socio-economic development, the pace of urban work is accelerating, and those who spend long hours in urban environments face increasing pressure from life and work. Against this backdrop, escaping the city's hustle and bustle during holidays and weekends for outdoor recreational activities such as camping and small gatherings has become an important way for many to relieve stress and relax. In these outdoor settings, sufficient and wide-coverage lighting is crucial for ensuring safety and enhancing the experience, highlighting the increasing importance of large-area portable lighting devices. Based on this, lamp holders have emerged, allowing lighting fixtures to be mounted on them to form portable lighting devices, which can initially alleviate the problem of insufficient outdoor lighting.

[0003] However, the lamp holder of the portable lighting device in the current related technology can only provide the lighting lamp with a single degree of rotational freedom adjustment function. The rotation range of the lighting lamp is strictly limited, and it is impossible to achieve flexible adjustment in multiple dimensions and angles according to the terrain differences, the distribution of people's activity areas and changes in lighting needs in the actual outdoor scene. Utility Model Content

[0004] The purpose of this application is to provide a lamp holder and lighting device, which aims to solve the technical problem of the limited rotational freedom of the lamp in current portable lighting devices.

[0005] The embodiments of this application are implemented as follows: Firstly, a lamp holder support is provided, comprising:

[0006] The support rod extends along the first preset axis;

[0007] A connecting assembly includes a connecting member, a mounting member, and multiple rotating members. The connecting member is rotatably connected to the end of the support rod about a first preset axis. The mounting member is rotatably connected to the connecting member about a second preset axis, which is perpendicular to the first preset axis. The multiple rotating members are rotatably connected to the mounting member, and at least two of the rotating members have different directions of rotation axis extension, and the rotation axis of each rotating member is perpendicular to the second preset axis. The rotating members are used to connect a lighting lamp.

[0008] In one embodiment of the first aspect, the connecting member includes a first damping shaft, a fixed seat, and a second damping shaft. The first damping shaft is rotatably connected to the end of the support rod about a first preset axis. The fixed seat is connected to the first damping shaft. The mounting member is rotatably connected to the fixed seat about a second preset axis via the second damping shaft.

[0009] In one embodiment of the first aspect, the support rod has a through hole, and the end of the support rod is provided with an end connector at least partially received within the through hole. The end connector includes a damping shaft fixing member and a waterproof connector. The damping shaft fixing member is sealed and connected to the opening of the through hole. The first damping shaft is sealed and connected to the damping shaft fixing member and has a first connecting hole. The waterproof connector is located within the through hole and is sealed and connected to the damping shaft fixing member. The waterproof connector has a through hole. Both the first connecting hole and the through hole are used for a wire to pass through. The wire is sealed and connected to the first connecting hole and / or the through hole.

[0010] In one embodiment of the first aspect, the mounting component has a through hole, and both ends of the second damping shaft are connected to the wall of the through hole.

[0011] As one embodiment of the first aspect, the connecting assembly further includes a cover connected to the mounting base and shielding the second damping shaft.

[0012] In one embodiment of the first aspect, the rotating component includes a first rotating member and a second rotating member. The first rotating member is rotatably connected to the mounting member via a third damping shaft about a third preset axis. The second rotating member is rotatably connected to the first rotating member via a fourth damping shaft about a fourth preset axis. The third preset axis is perpendicular to the second preset axis, and the fourth preset axis is perpendicular to the third preset axis. The second rotating member is used to connect a lighting lamp. In this embodiment, the third preset axes of the first rotating members in at least two of the rotating components are not parallel.

[0013] In one embodiment of the first aspect, four rotating members are provided, and the four rotating members are spaced apart circumferentially around the mounting member.

[0014] In one embodiment of the first aspect, among the four rotating members, the third preset axis of the first rotating member in the two opposite rotating members is parallel.

[0015] In one embodiment of the first aspect, the mounting member has multiple sets of rotating ears, each rotating ear corresponding to a first rotating member. Each rotating ear includes two spaced-apart ears, and each first rotating member is located between two ears. The two ends of the third damping shaft are respectively connected to one of the ears, and the second rotating member is rotatably connected to the third damping shaft.

[0016] Secondly, a lighting device is provided, including a lighting lamp and a lamp holder as described in the above embodiments, wherein the lighting lamp is connected to the rotating member.

[0017] The technical advantages of this application embodiment compared to the prior art are as follows: The lamp head support, through the coordinated design of the support rod and the connecting component, utilizes the rotation of the connecting component around the first preset axis, the rotation of the mounting component around the second preset axis perpendicular to the first preset axis, and the rotation of multiple rotating components with different extension directions and all perpendicular to the second preset axis to construct a multi-degree-of-freedom adjustment system. The rotation axes of at least two rotating components in different directions can support each rotating component to drive the connected lighting lamp (or multiple groups of lighting lamps) to achieve differentiated angle adjustment, covering multiple angles for three-dimensional adjustment. This allows the lighting lamp to achieve flexible adjustment in all directions and multiple angles, completely breaking the limitation of the traditional support on the rotation range of the lamp head. It can accurately adapt to complex outdoor terrain differences (such as undulating campsites and sloping sites), dynamically changing personnel activity area distribution (such as switching between dining areas, game areas, and rest areas), and diverse lighting needs (such as large-area environmental lighting, local key lighting, and specific angle directional lighting), ensuring that it can provide the best lighting coverage effect in different scenarios. The lamp holder features a simple yet robust multi-degree-of-freedom adjustable structure. The adjustment of each rotating part is convenient, allowing users to quickly adjust the angle and height of the lamp without complicated operations. This design balances ease of use with long-term structural stability, enhancing the outdoor experience and applicability of portable lighting devices while also strengthening the product's market competitiveness.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0032] In the process of continuous socio-economic development, the pace of urban work is accelerating, and those who spend long hours in urban environments face increasing pressure from life and work. Against this backdrop, escaping the city's hustle and bustle during holidays and weekends for outdoor recreational activities such as camping and small gatherings has become an important way for many to relieve stress and relax. In these outdoor settings, sufficient and wide-coverage lighting is crucial for ensuring safety and enhancing the experience, highlighting the increasing importance of large-area portable lighting devices. Based on this, lamp holders have emerged, allowing lighting fixtures to be mounted on them to form portable lighting devices, which can initially alleviate the problem of insufficient outdoor lighting.

[0033] This application provides a lighting device, which includes a lamp and a lamp holder. The lamp can be installed on the lamp holder, and the installation method can be detachable or fixed, without limitation. As the core component for supporting and adjusting the lighting device, the lamp holder provides rigid support for the lamp and raises the illumination height of the lamp, effectively reducing the obstruction of light by ground obstacles (such as camping equipment, vegetation, tables and chairs). This allows the light to cover a larger area (such as camping sites or gathering areas) at a better angle, while avoiding problems such as concentrated light and obvious blind spots caused by excessively low illumination height.

[0034] However, the lamp holder of the portable lighting device in the current related technology can only provide the lighting lamp with a single degree of rotational freedom adjustment function. The rotation range of the lighting lamp is strictly limited, and it is impossible to achieve flexible adjustment in multiple dimensions and angles according to the terrain differences, the distribution of people's activity areas and changes in lighting needs in the actual outdoor scene.

[0035] In view of the above problems, this application also provides a lamp holder that can realize multi-angle adjustment of the lighting lamp to meet the lighting needs in different scenarios.

[0036] Please see Figure 1 In this embodiment of the application, the lamp holder includes a support rod 10 and a connecting component 20.

[0037] The support rod 10 can be a straight rod structure, extending along a first preset axis s1. The support rod 10 has a first extension end 10a and a second extension end 10b, and the connecting assembly 20 can be connected to the first extension end 10a. In use, the support rod 10 can be placed vertically, with the first extension end 10a positioned above the second extension end 10b. The second extension end 10b can be connected to other structural components, such as a movable base, other support arms, or a connecting structure for connecting with other structural components. The support rod 10 can be made of high-strength materials, such as aluminum alloy or high-strength engineering plastics, to withstand the weight load of the lighting fixture and ensure that the lighting fixture does not tilt or fall off during use. The support rod 10 can be a non-deformable straight rod structure or a deformable structure, such as capable of telescopic or folding deformation, to reduce space occupation during storage and to raise the installation height of the lighting fixture according to actual lighting needs, thereby increasing the height of the lighting fixture's illumination center point.

[0038] In other embodiments, the support rod 10 may also extend along a non-linear path, such as along an arc path or a broken line path, or only a portion near the first extension end 10a may extend along the first preset axis s1; there are no restrictions on this.

[0039] The connecting assembly 20 includes a connecting member 21, a mounting member 22, and multiple rotating members 23. The connecting member 21 is rotatably connected to the end of the support rod 10 about a first preset axis s1, meaning the connecting member 21 is rotatably connected to the first extension end 10a of the support rod 10 and can rotate about the first preset axis s1. The mounting member 22 is rotatably connected to the connecting member 21 about a second preset axis s2, which is perpendicular to the first preset axis s1, meaning the mounting member 22 is rotatably connected to the connecting member 21 and can rotate about the second preset axis s2. The mounting member 22 can rotate in two degrees of freedom via the connecting member 21. Multiple rotating members 23 are rotatably connected to the mounting member 22, with at least two rotating members 23 having different directions of rotation axis extension, and each rotating member 23 having a rotation axis perpendicular to the second preset axis s2. The rotating members 23 are used to connect lighting lamps. It should be noted that the rotating component 23, the mounting component 22 and the connecting component 21 can be subjected to damping force during rotation so that they can be suspended at the current angle after the external force is removed. They can also have rotation positions so that they can automatically rotate to the position corresponding to the angle and remain suspended after the external force is removed. They can also achieve suspension at the current angle through external structural components. There are no restrictions here.

[0040] This lamp holder, through the collaborative design of the support rod 10 and the connecting component 20, utilizes the rotation of the connecting component 21 around the first preset axis s1, the rotation of the mounting component 22 around the second preset axis s2 perpendicular to the first preset axis s1, and the rotation of multiple rotating components 23 with different directions of rotation axis extension, all perpendicular to the second preset axis s2, to construct a multi-degree-of-freedom adjustment system. The rotation axes of at least two rotating components 23 in different directions can support each rotating component 23 to drive the connected lighting lamp (or multiple groups of lighting lamps) to achieve differentiated angle adjustment, covering multiple angles for three-dimensional adjustment. This allows the lighting lamp to achieve flexible adjustment in all directions and multiple angles, completely breaking the limitations of traditional holders on the rotation range of the lamp head. It can accurately adapt to complex outdoor terrain differences (such as undulating campsites and sloping sites), dynamically changing personnel activity area distribution (such as switching between dining areas, game areas, and rest areas), and diverse lighting needs (such as large-area ambient lighting, local key lighting, and specific angle directional lighting), ensuring that it can provide the best lighting coverage effect in different scenarios. The lamp holder features a simple yet robust multi-degree-of-freedom adjustable structure. The adjustment of each rotating part is convenient, allowing users to quickly adjust the angle and height of the lamp without complicated operations. This design balances ease of use with long-term structural stability, enhancing the outdoor experience and applicability of portable lighting devices while also strengthening the product's market competitiveness.

[0041] Please see Figure 2 and Figure 3In some embodiments, the connecting member 21 includes a first damping shaft 211, a fixing seat 212, and a second damping shaft 213. The first damping shaft 211 is arranged around a first preset axis s1 (connected to...). Figure 1 The first preset axis s1 coincides with the central axis of the first damping shaft 211. The first damping shaft 211 can be damped and rotated relative to the first extension end 10a of the support rod 10. After the user adjusts the angle of the connecting member 21 relative to the support rod 10, the damping characteristics allow the connecting member 21 to be stably suspended at the current angle when the external force is removed, avoiding the connection member 21 from shifting as the external force disappears due to lack of damping or insufficient damping, and ensuring that the lighting lamp is accurately positioned in the direction of the first preset axis s1. The fixed base 212 is connected to the first damping shaft 211. The mounting component 22 is rotatably connected to the fixed base 212 via the second damping shaft 213 around the second preset axis s2. The second preset axis s2 coincides with the central axis of the second damping shaft 213. The second damping shaft 213 can be fixedly connected to the mounting component 22 and rotate with damping relative to the fixed base 212, or it can be fixedly connected to the fixed base 212 and rotate with damping relative to the mounting component 22. After the user adjusts the angle of the fixed base 212 relative to the mounting component 22, the damping characteristics allow the connecting component 21 to be stably suspended at the current angle when the external force is removed. The setting of the first damping shaft 211 and the second damping shaft 213 effectively solves the problem that the lamp head is prone to angular displacement due to its own weight and slight vibration (such as outdoor wind or human touch) in traditional undamped rotating structures. This allows users to easily and accurately fix the lighting lamp at any desired adjustable angle without the need for an additional locking structure to maintain a stable lighting position. The damped rotation design simplifies the operation process, allowing users to adjust the angle directly with external force without tools. The adjustment process is smooth and without any jamming. It can also withstand the weight load of the lighting lamp for a long time. Even after long-term use in complex outdoor environments, the damping performance decays slowly, ensuring the stability of the angle suspension effect. This further improves the reliability and user experience of the portable lighting device in outdoor camping, small gatherings, and other scenarios. In addition, the mounting base 212 provides a stable mounting foundation for the mounting component 22, ensuring that the rotational adjustment of the first damping shaft 211 and the second damping shaft 213 does not interfere with each other, ensuring a smooth and orderly multi-degree-of-freedom adjustment process.

[0042] Please see Figure 3 In some embodiments, the support rod 10 has a through hole 101 extending through the support rod 10 along the first preset axis s1, meaning the support rod 10 is a hollow rod. This reduces the weight of the support rod 10, meeting the outdoor mobility needs of portable lighthouses and making it easier for users to carry and assemble, effectively improving the overall portability of the product. An end connector 11 is provided at the end of the support rod 10, i.e., the end of the first extension end 10a, at least partially housed within the through hole 101.

[0043] The end connector 11 includes a damping shaft fixing member 111 and a waterproof connector 112. The damping shaft fixing member 111 is sealed to the opening of the through hole 101 and is located at the first extension end 10a of the support rod 10. The first damping shaft 211 is sealed to the damping shaft fixing member 111. Specifically, the damping shaft fixing member 111 has a first fixing hole 1111, through which the first damping shaft 211 passes and is sealed to the hole wall of the first fixing hole 1111. The first damping shaft 211 has a first connecting hole 2110, which extends through the first damping shaft 211 along the extension direction of the first preset axis s1. The waterproof connector 112 is located inside the through hole 101, that is, inside the through hole 101 relative to the first damping shaft 211. The waterproof connector 112 is sealed to the damping shaft fixing member 111. Specifically, the damping shaft fixing member 111 also has a second fixing hole 1112. The waterproof connector 112 is tubular and passes through the second fixing hole 1112. The outer peripheral surface of the waterproof structure is sealed to the hole wall of the second fixing hole 1112. The waterproof connector 112 has a first through hole 1120, which extends through the waterproof connector 112 along the extension direction of the first preset axis s1. Both the first connecting hole 2110 and the first through hole 1120 are used for wires to pass through. One end of the wire can be connected to a power source. The wire passes through the through hole 101 and then sequentially through the first through hole 1120 and the first connecting hole 2110 before exiting the support rod 10. The other end of the wire is electrically connected to the lighting lamp connected to the rotating member 23 to realize the power supply to the lighting lamp. The conductor is sealed to the wall of the first connecting hole 2110 and the wall of the first through hole 1120, preventing external rainwater and dew from entering the support rod 10 through gaps such as the opening of the through hole 101, the first connecting hole 2110, and the first through hole 1120. This prevents the conductor and other electrical components inside the through hole 101 from getting wet, effectively coping with complex outdoor environments such as humidity and rain, significantly reducing the risk of short circuits and component damage, and ensuring the long-term stable operation of the lighting device. The conductor runs along the path of the through hole 101, the first through hole 1120, and the first connecting hole 2110, avoiding the conductor being exposed and worn, and using the hollow rod to hide the wiring, making the overall structure simpler. The conductor can rotate relative to the first connecting hole 2110 and the first through hole 1120 to accommodate the multi-degree-of-freedom rotation of the mounting component 22 around the connecting member 21, effectively preventing problems such as conductor breakage and insulation damage due to excessive twisting during adjustment, ensuring the reliability of the power supply line, and ensuring continuous and stable lighting. In other embodiments, either the first connecting hole 2110 or the first through hole 1120 may be sealed to the wire, which is not a limitation.

[0044] Please see Figure 4Optionally, the mounting component 22 includes a mounting base 22a and a mounting cover 22b. The mounting base 22a and the mounting cover 22b are detachably connected and together form a mounting cavity 220. The mounting cover 22b also has a second through hole 2202. A connector 222 is also provided at the second through hole 2202 of the mounting component 22. The connector 222 can be connected to the bellows of the lighting lamp so that the wires in the bellows pass through the connector 222 into the mounting cavity 220 and then pass out of the mounting cavity 220 through the first connecting hole 2110. The mounting cavity 220 is provided to protect the wires and prevent them from being worn at the mounting component 22.

[0045] Please see Figure 4 In some embodiments, the mounting component 22 has a through hole 2201 through which the mounting component 22 can pass. There are two second damping shafts 213, both of which are connected to the hole wall of the through hole 2201. This distributes the radial force and torque on the second damping shaft 213 evenly to the two side holes of the through hole 2201, preventing the connection between the damping shaft and the mounting component 22 from loosening, deformation, or even breakage due to concentrated force during long-term use. At the same time, the structure with fixed ends makes it difficult for the second damping shaft 213 to deviate radially during rotation, and it can always maintain precise rotation around the second preset axis s2. This avoids problems such as unstable damping torque and adjustment jamming caused by shaft shaking, allowing users to obtain a smoother and more comfortable operating experience when adjusting the angle of the mounting component 22, and can accurately control the rotation angle of the lamp head, further improving the accuracy of angle adjustment. This connection method eliminates the need for additional support structures on the outside of the mounting component 22. It also reduces the size and weight of the mounting component 22 through the through hole 2201. This not only meets the design requirements for lightweight portable lighthouses but also avoids the obstruction or restriction of the rotation range of the lamp head by the external support structure. It ensures that the rotation stroke of the mounting component 22 around the second preset axis s2 is not affected, thus adapting to the multi-angle adjustment needs of lighting in various outdoor scenarios.

[0046] Optionally, the central axis of the through hole 2201 can coincide with the central axis of the mounting component 22 to achieve balanced force during the rotation of the mounting component 22, so that the second damping shaft 213 can evenly bear the weight load of the mounting component 22 and the connected lighting lamp, avoid local force concentration caused by axis offset, reduce the risk of structural wear or deformation after long-term use, and improve the durability of the damping rotation structure.

[0047] Please see Figure 3 and Figure 4Optionally, the mounting base 212 includes a mounting plate 2121 and two mounting ears 2122 disposed on the mounting plate 2121. The two mounting ears 2122 are spaced apart and each has a rotating hole 21220. Each second damping shaft 213 passes through a rotating hole 21220 and can rotate relative to the corresponding mounting ear 2122 with damping. The two mounting ears 2122 can respectively fit with the wall of the through hole 2201 to form a bidirectional axial constraint on the mounting component 22, effectively limiting the swaying or displacement of the two second damping shafts 213 along their own axis during rotation. This avoids problems such as unstable damping torque, adjustment jamming, or even loose connection between the second damping shaft 213 and the mounting ear 2122 and the mounting component 22 due to axial movement. Especially in outdoor scenarios where the lamp head is frequently adjusted or subjected to slight impacts, this ensures that the second damping shaft 213 is always on the preset rotation trajectory, guaranteeing the stability of the connection between the mounting component 22 and the mounting base 212. Two spaced fixed ears 2122 jointly support the second damping shaft 213 through the rotating hole 21220. They can also evenly distribute the weight of the mounting part 22 and the rotational torque borne by the two second damping shafts 213 to the fixed plate 2121, avoiding localized stress concentration caused by single fixed ear 2122 support, reducing wear at the connection between the fixed ear 2122 and the damping shaft, and extending the service life of the damping rotation structure.

[0048] The second damping shaft 213 has a second connecting hole 2130. The wire can pass through the first connecting hole 2110, enter the second connecting hole 2130 through the rotating hole 21220, pass through the second connecting hole 2130 and enter the mounting cavity 220, and then pass through the connector 222 and enter the bellows of the lighting lamp to finally achieve electrical connection with the lighting lamp.

[0049] Please see Figure 4 In some embodiments, the connecting assembly 20 further includes a cover 24, which is connected to the fixing base 212 and shields the second damping shaft 213. The cover 24 can completely shield the second damping shaft 213 and the rotation hole 21220 of the fixing lug 2122, effectively preventing dust, sand, fallen leaves and other impurities in the outdoor environment from entering the gap between the rotation hole 21220 and the damping shaft. This avoids the second damping shaft 213 from jamming, increasing frictional resistance, or even wearing of the mating surface due to the intrusion of impurities. It ensures that the second damping shaft 213 maintains a smooth damping rotation effect for a long time, maintains the stability of the damping torque, and allows users to obtain precise angle hovering and smooth operation even after multiple adjustments.

[0050] Please see Figure 5 and Figure 6In some embodiments, the rotating member 23 includes a first rotating member 231 and a second rotating member 232. The first rotating member 231 rotates around a third preset axis s3 via a third damping shaft 2311. Figure 1 The first rotating member 231 is rotatably connected to the mounting member 22, and the third preset axis s3 coincides with the central axis of the third damping shaft 2311. The first rotating member 231 can be damped relative to the mounting member 22 by the third damping shaft 2311. The third damping shaft 2311 can be fixedly connected to the first rotating member 231 and rotatably connected to the mounting member 22, or it can be fixedly connected to the mounting member 22 and rotatably connected to the first rotating member 231; this is not limited here. The second rotating member 232 is connected to the fourth damping shaft 2321 around the fourth preset axis s4 (in conjunction with...). Figure 1 The fourth preset axis s4 is rotatably connected to the first rotating member 231, and its central axis coincides with that of the fourth damping shaft 2321. The second rotating member 232 can be damped relative to the mounting member 22 by the fourth damping shaft 2321. The fourth damping shaft 2321 can be fixedly connected to the second rotating member 232 and rotatably connected to the first rotating member 231, or it can be fixedly connected to the first rotating member 231 and rotatably connected to the second rotating member 232; this is not limited here. The third preset axis s3 is perpendicular to the second preset axis s2, and the fourth preset axis s4 is perpendicular to the third preset axis s3. The second rotating member 232 is used to connect a lighting lamp. The third damping shaft 2311 drives the first rotating component 231 to rotate around a third preset axis s3 perpendicular to the second preset axis s2, enabling the lighting lamp to add a lateral adjustment dimension in addition to the "adjustment direction of the second preset axis s2"; while the fourth damping shaft 2321 drives the second rotating component 232 to rotate around a fourth preset axis s4 perpendicular to the third preset axis s3, further expanding the adjustment dimension. The three work together to form a "three-dimensional adjustment space". For example, the second preset axis s2 (combined with...) Figure 1 This system enables tilt adjustment of the lamp head, left and right swaying via the third preset axis s3, and horizontal rotation via the fourth preset axis s4. It completely breaks the limitations of traditional single or two-dimensional adjustments, allowing the light to be precisely aimed at any direction, easily covering uneven and scattered lighting areas in outdoor camping and gatherings. The adjustments of the first rotating component 231 and the second rotating component 232 do not interfere with each other; users can independently control the rotation angle in each dimension, such as adjusting the lamp head tilt to avoid obstacles or rotating the lamp head to focus on a specific area. Simultaneously, the second rotating component 232 is directly connected to the light, and its graded damping rotation structure effectively buffers the impact during adjustment, reducing lamp head wobbling and ensuring lighting stability.

[0051] Optionally, the third preset axis s3 of the first rotating member 231 in at least two rotating members 23 (in conjunction with) Figure 1The lighting is not parallel. When multiple rotating components 23 are connected to lighting lamps, each lamp can obtain a differentiated lateral adjustment reference based on its own non-parallel third preset axis s3. This allows the adjustment range of multiple lamps to complement each other in space, easily covering oblique and multi-angle lighting areas that are difficult to reach with traditional parallel axis designs. This effectively eliminates lighting blind spots caused by terrain undulations and obstacles during outdoor camping and gatherings. The non-parallel third preset axis s3 allows the lighting lamps of different rotating components 23 to be adjusted independently according to the needs of the area. Without relying on the overall moving lamp head support, the lighting adjustment of the multi-lamp head system can be more targeted through differentiated angle adjustment. This avoids the overlapping and waste of lighting range caused by parallel axes, and can create a more uniform and comprehensive lighting environment through multi-dimensional and multi-directional light combinations, further enhancing the practical value and user experience of portable lighthouses in various outdoor scenarios.

[0052] Please see Figure 5 For example, four rotating members 23 are provided, and the four rotating members 23 are arranged circumferentially around the mounting member 22. The four circumferentially spaced rotating members 23 can each be equipped with four sets of lighting lamps, so that the lighting range is evenly extended along the circumference of the mounting member 22, reducing the circumferential lighting blind spots.

[0053] Optionally, in the four rotating components 23, the third preset axis s3 of the first rotating member 231 in the two opposite rotating components 23 are parallel. That is, the included angle between two adjacent rotating components 23 can be 90°. In this way, the four rotating components 23 can be arranged in pairs opposite each other to evenly distribute the weight load of each rotating component 23 and the connected lighting lamps to the circumference of the mounting component 22. This avoids local stress concentration on the mounting component 22 due to uneven component distribution, effectively reducing problems such as deformation of the mounting component 22 and accelerated wear of the damping shaft after long-term use. At the same time, the oppositely arranged rotating components 23 can form a "reverse force cancellation" effect, reducing the load pressure at the connection between the mounting component 22 and the fixed base 212, ensuring that the overall structure remains stable under the condition of multiple lamp heads. The circumferential distribution of two adjacent rotating components 23 at 90° intervals allows the four rotating components 23 to correspond to the four basic directions of "front, back, left, and right", respectively, to achieve full directional coverage and multi-dimensional adjustment. 360° ring lighting coverage can be achieved without moving the lighthouse, and the brightness and angle of each direction of lighting can be adjusted independently. In addition, the paired structure allows users to more intuitively control the symmetry of the lighting when adjusting it, avoiding situations where the local lighting is too strong or too weak, and helping to create a uniform and comprehensive lighting environment.

[0054] Please see Figure 6Optionally, the mounting component 22 has multiple sets of rotating ears 221, each corresponding to a first rotating component 231. Each rotating ear 221 includes two spaced-apart ears 2211, with each first rotating component 231 located between the two ears 2211. The two ends of the third damping shaft 2311 are respectively connected to one ear 2211, and the second rotating component 232 is rotatably sleeved on the third damping shaft 2311, allowing for damped rotation relative to the third damping shaft 2311. The two spaced-apart ears 2211 of each set of rotating ears 221 form a "clamping" support structure, stably limiting the first rotating component 231 between the two ears 2211. Combined with the connection between the two ends of the third damping shaft 2311 and the ears 2211, this effectively limits the radial offset of the first rotating component 231 during rotation, avoiding wobbling and loosening problems caused by single-end support or the absence of a clamping structure. In outdoor scenarios, when the lamp head is subjected to its own weight or minor impacts, the clamping structure can distribute the load on the first rotating component 231, reduce the wear of the connection between the third damping shaft 2311 and the ear 2211, and ensure that the rotating structure remains stable and reliable after long-term use.
