lighting fixtures

[0001] This application claims priority to Chinese Patent Application No. CN2024110484029, filed with the Chinese Patent Office on July 31, 2024, entitled "Lighting Device", the entire contents of which are incorporated herein by reference.

[0002] Technical Field

[0003] This invention relates to the field of lighting technology, and in particular to a lighting device.

[0004] Background Technology

[0005] Typically, lighting fixtures, as electrical appliances, have multiple support legs that can switch between folded and unfolded states. In the folded state, users can hold the lighting fixture for illumination, while in the unfolded state, users can place the lighting fixture on a table for illumination. However, in traditional lighting fixtures, the light-emitting components cannot be stably maintained in the folded state after the multiple support legs are stowed. The light-emitting components are easily affected by external forces, leading to risks such as damage and poor contact.

[0006] Application content

[0007] The present invention provides a lighting device to solve the technical problems of traditional lighting devices where the light-emitting components cannot be stably maintained in the stored state after being stored, and the light-emitting components are easily damaged or have poor contact due to shaking caused by external forces.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A lighting device, comprising:

[0010] A support rod having a mounting end and a support end opposite each other along its axial direction;

[0011] The movable rod has a first connecting end and a second connecting end that are opposite each other along its axial direction. The first connecting end is rotatably connected to the mounting end. When the first connecting end rotates relative to the mounting end, the angle between the movable rod and the support rod changes, and the movable rod can be flipped to be parallel to the support rod.

[0012] The lamp head is connected to the second connecting end. The lamp head includes a connected lamp housing and a lamp source. The lamp housing can be fastened to the supporting end when the movable rod and the supporting rod are in a side-by-side close-up posture.

[0013] As can be seen from the above technical solutions, the embodiments of the present invention have at least the following advantages and positive effects:

[0014] This invention provides a lighting device in which a movable rod can rotate relative to a supporting end until the movable rod and supporting rod are side-by-side. Simultaneously, the lamp head can be tightly fastened to the supporting end to complete the folding and storage of the entire lighting device, maintaining the side-by-side alignment of the movable and supporting rods. The relative rotation of the supporting and movable rods does not interfere with the lamp head, and the storage process of this lighting device is convenient and simple. In the folded state, the user can hold both the supporting rod and the movable rod to use it as a flashlight or floodlight. In the folded state, the lighting device has a long rod-like structure with the lamp head far from the supporting end. The user can hold the supporting end to use the lighting device as a detector, or support the supporting rod on a surface to use it as a table lamp. Therefore, the lighting device provided by this invention is not only convenient for folding, storage, and carrying, but also provides different lighting functions in different states, enhancing its practicality and multi-functionality. Furthermore, because the supporting rod and the movable rod are rotatably connected, the lighting direction of the lamp head can be changed to meet more of the user's lighting needs. Finally, after the lighting device of the present invention is stored, the lamp head is tightly fastened to the support end. The support rod, movable rod and lamp head in this solution are connected end to end to form a closed frame structure, so as to improve the stability of the entire lighting device in the stored state, reduce the lamp head from shaking due to external forces, and play a role in protecting the lamp head.

[0033] Detailed Implementation

[0034] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] Referring to Figures 1 and 2, this application provides a conveniently foldable and foldable lighting device 10 that can switch between an unfolded state and a folded state. Figure 1 illustrates the folded state of the lighting device 10, in which it can be held and carried by the user to provide illumination. For example, the user can easily hold the lighting device to obtain light, facilitating activities at night. Simultaneously, when the lighting device 10 is folded, its size and space-saving design make it convenient for storage and carrying. Figure 2 illustrates the unfolded state of the lighting device 10. In the unfolded state, the lighting device 10 has a higher illumination height and a wider illumination range. In this state, the user can hold it by hand, providing illumination over a wide area during outdoor camping, or using it as a mobile streetlight or detector during nighttime travel, facilitating both navigation and observation of the surrounding environment. Alternatively, referring to Figure 3, in other usage scenarios, the lighting device 10 can be further unfolded into a stand state to provide lighting functionality on a flat or uneven support surface. For example, when reading or using a computer at home at night, appropriate lighting is needed to protect the eyes from strong light damage. In this case, the lighting device 10 can be supported on a table and used as a desk lamp. It should be understood that in this application, the lighting device 10 does not necessarily need to be unfolded into a stand state; it only needs to be able to be folded and stored. In addition, if the supporting body of the lighting device 10 is sufficiently robust, the user can also directly support the unfolded lighting device 10 on the support surface.

[0038] Referring to Figures 1 and 2, the lighting device 10 includes a support rod 100, a movable rod 200, and a lamp head 300 connected in sequence. The lamp head 300 is connected to the free end of the movable rod 200. The movable rod 200 tilts relative to the support rod 100, allowing the entire lighting device 10 to switch freely between an unfolded state and a folded state.

[0039] Specifically, the support rod 100, as the supporting body, has a supporting end 101 and a mounting end 102. When the lighting device 10 is in the unfolded state, the support rod 100 can support the lighting device 10 on the supporting surface. The movable rod 200 has a first connecting end 201 and a second connecting end 202. The first connecting end 201 is rotatably connected to the mounting end 102. When the first connecting end 201 rotates relative to the mounting end 102, the angle between the movable rod 200 and the support rod 100 changes, and the movable rod 200... The movable rod 200 can be flipped to be parallel to the support rod 100. At this time, the movable rod 200 is folded and stored on the side of the support rod 100, so that the lighting device 10 can switch from the unfolded state to the stored state. The lamp head 300, as the light-emitting component of the lighting device 10, emits light to provide a light source for the user. The lamp head 300 is connected to the second connecting end 202. The lamp head 300 includes a lamp housing 310 and a light source 320 disposed in the lamp housing 310. The lamp housing 310 protects the light source 320 from external impacts. As shown in Figure 1, when the lighting device 10 is in the stored state, that is, when the movable rod 200 and the support rod 100 are in a parallel and close posture, the lamp housing 310 is fastened to the support end 101 of the support rod 100. Here, fastening means that the two are tightly connected, which can be achieved by means of buckles, hooks, adhesives, magnets, etc. The lamp housing 310 is fastened to the support end 101, including but not limited to the lamp housing 310 being able to fasten to the side, edge, and bottom of the support end 101.

[0040] Specifically, referring to Figure 3, when using the lighting device 10, the user can apply external force to the support rod 100, which unfolds the support rod 100. In the unfolded state, the support rod 100 forms a tripod structure. The lighting device 10, in this unfolded state, can be placed on the flat or uneven support surface described above. The lighting device 10 provides illumination as a table lamp. At this time, the support rod 100 supports and fixes the movable rod 200 and the lamp head 300. When the lighting device 10 is placed on the support surface via the tripod structure, the movable rod 200 can swing up and down along the axis of the support rod 100 to change the lighting height. Simultaneously, the movable rod 200 can also rotate circumferentially around the central axis of the support rod 100 to change the circumferential orientation of the lighting, meeting different lighting needs of the user. When the movable rod 200 swings circumferentially relative to the support rod 100 to any angle, the lamp head 300 located at the free end of the movable rod 200 can be directly fastened to the support end 101 by tilting and folding the movable rod 200. This means that in actual use, regardless of how the illumination angle of the lamp head 300 is adjusted, the lamp head 300 can be directly fastened to the support end 101 by tilting and folding the movable rod 200, without having to swing the movable rod 200 to a fixed position beforehand. This greatly simplifies the folding operation of the lighting device 10 and shortens the time for the user to fold and fasten the lighting device 10. In addition, it should be noted that in other embodiments, the movable rod 200 can also be set to not swing circumferentially relative to the support rod 100, that is, the circumferential angle adjustment of the movable rod 200 is not mandatory.

[0041] More specifically, in this embodiment, referring to Figures 2 and 3, the support rod 100 includes a connected rod body 110 and multiple support legs 120. The two opposite ends of the rod body 110 along its axial direction correspond to the support end 101 and the mounting end 102 mentioned above, respectively. The multiple support legs 120, as support components, can switch between a closed state and an extended state. Each support leg 120 has a corresponding rotating end 121 and a fixed end 122. The rotating end 121 is rotatably connected to the side periphery of the rod body 110. When the rotating end 121 flips outward toward the outside of the rod body 110, it simultaneously drives the multiple fixed ends 122 to switch from a closed state to a support state where they are close to each other to a support state where they are far apart from each other. The multiple support legs 120 switch from a closed state (as shown in Figure 2) to a support state (as shown in Figure 3, which is the triangular support frame state mentioned above). When the multiple support legs 120 are in the closed state, they are arranged side by side against the side of the pole 110 and surround it. In this state, the user can also continue to operate to flip and fold the movable pole 200 so that the movable pole 200 and the support pole 100 are side by side, which is the storage state of the lighting device 10 as shown in Figure 1. The user can hold the support pole 100 and the movable pole 200 at the same time and use the lighting device 10 as a flashlight for illumination.

[0042] It is important to understand that, firstly, the multiple support legs 120 enhance the support function of the support rod 100. In other embodiments, when the radial dimension of the support rod 100 is sufficiently large, the end face area of ​​the support end 101 is large and flat. In this case, the support rod 100 can be directly supported on the support surface through the end face of the support end 101, thus eliminating the need for additional support legs 120 to enable the support rod 100 to function as a support frame. Secondly, the deployment method of the multiple support legs 120 can be as described in this embodiment, where the support legs 120 are flipped outward relative to the outer wall of the rod 110. In other embodiments, the multiple support legs 120 can also be deployed by rotating circumferentially along the rod 110, as long as the multiple support legs 120 can switch between the closed state and the supported state.

[0043] Preferably, the support rod 100 has a cylindrical shape, which improves the user's grip when the lighting device 10 is in its retracted state, making it easier to carry and use. It is also easier to manufacture. It should be understood that in other embodiments, without considering grip comfort and ease of manufacturing, the support rod 100 can also be an ellipse, a triangular prism, a square prism, etc.; that is, this application does not limit the shape of the support rod 100.

[0044] Preferably, in this embodiment, referring to Figures 3 and 4, the movable rod 200 includes a fixed rod 210 and a telescopic rod 220 connected together. The fixed rod 210 is rotatably connected to the mounting end 102 at the first connecting end 201, and the telescopic rod 220 is connected to the lamp housing 310 at the second connecting end 202. The telescopic rod 220 is movably sleeved on the fixed rod 210 and can reciprocate axially relative to the fixed rod 210, so that the movable rod 200 can extend or shorten to change its length, and at the same time change the distance between the lamp head 300 and the support rod 100. Here, it should be understood that, firstly, the fixed rod 210 and the telescopic rod 220 are relative terms, representing two tubular components that can be connected end to end and can extend or retract relative to each other; that is, in other embodiments of this application, the connection can also be as follows: the fixed rod 210 is connected to the lamp housing 310 at the second connecting end 202, and the telescopic rod 220 is rotatably connected to the mounting end 102 at the first connecting end 201. Secondly, the number of telescopic rods 220 can be one or more. The more there are, the greater the range of telescopic length. The telescopic rods 220 are generally connected in sequence according to the radial size of the pipe fitting. Small-sized pipe fittings can be concealed inside or extended out of the larger-sized pipe fittings. In this embodiment, there are multiple telescopic rods 220, and the radial size decreases from the inside to the outside as they are connected and is smaller than the radial size of the fixed rod 210. This allows the telescopic rods 220 to be concealed inside the fixed rod 210.

[0045] Referring to Figures 3 and 4, when the lighting device 10 is in the unfolded state, with the angle between the axes of the movable rod 200 and the support rod 100 fixed, the movable rod 200 can change its length by extending and retracting, thereby changing the distance between the first connecting end 201 and the second connecting end 202, and thus changing the distance between the support rod 100 and the lamp head 300, thereby changing the illumination distance of the lamp head 300.

[0046] Referring to Figures 1 and 5, when the lighting device 10 is in the retracted state, the lamp head 300 moves closer to or further away from the support end 101 as the movable rod 200 extends and retracts. Finally, the lamp head 300 can be fastened to the bottom of the support end 101. At this time, the support end 101 and multiple fixed ends 122 can be fastened to the lamp housing 310 simultaneously.

[0047] Preferably, referring to Figures 1 and 6, in this embodiment, the lamp head 300 is rotatably connected to the second connecting end 202 to achieve the flipping of the lamp head 300. The lamp head 300 swings along the axial direction of the movable rod 200 to achieve the flipping relative to the second connecting end 202. When the movable rod 200 and the support rod 100 are in a side-by-side close-up posture, the lamp housing 310 flips, causing the lamp head 300 to rotate synchronously until it is engaged with the bottom of the support end 101. At this time, the fixed ends 122 of the multiple support legs 120 are simultaneously engaged with the lamp housing 310.

[0048] Referring to Figures 5 and 6, in this embodiment, the lamp head 300 can move closer to or further away from the support rod 100 via the movable rod 200, and can also swing relative to the movable rod 200 by rotating its connection to the rod, thereby flexibly changing the lighting direction. It should be understood that in other embodiments of this application, the lamp head 300 is detachably connected to the movable rod 200. The user can detach the lamp head 300 from the second connecting end 202 according to the desired lighting direction, and then freely rotate and extend the movable rod 200 to adjust the target lighting direction before reinstalling the lamp head 300 on the second connecting end 202. Furthermore, the detachable lamp head 300 can be stored and protected separately, and different models of lamp heads 300 can be replaced at any time according to usage needs. Different models of lamp heads 300 can have different shapes, different light colors, different light wattages, etc. Of course, in another embodiment, the lamp head 300 is non-detachably connected to the second connecting end 202, and the user can also adjust the lighting direction of the lamp head 300 through rotation, extension, and other operations. Therefore, in this application, it is not limited whether the lamp holder 300 is detachably connected to the second connection end 202.

[0049] It should be understood that in other embodiments, on the one hand, the lamp head 300 cannot swing relative to the movable rod 200. When the first connecting end 201 of the movable rod 200 is flipped relative to the mounting end 102 to a position where the movable rod 200 and the support rod 100 are side by side, the second connecting end 202 of the movable rod 200 moves closer to or away from the support end 101 through the extension and retraction of the movable rod 200, and at the same time drives the lamp head 300 to move closer to or away from the support end 101. The fastening surface of the lamp head 300 faces the support end 101, so the lamp head 300 can be fastened to the bottom of the support end 101 simply by extending and retracting the movable rod 200. On the other hand, the movable rod 200 cannot extend or retract. When the first connecting end 201 of the movable rod 200 is flipped relative to the mounting end 102 to a position where the movable rod 200 and the support rod 100 are side by side, the lamp head 300 can be fastened to the bottom of the support end 101 simply by flipping it, and the fixed ends 122 of the multiple support legs 120 are simultaneously fastened to the lamp head 300.

[0050] Preferably, referring to Figure 6 or Figure 7, the latching surface of the lamp housing 310 has a mounting groove 330, and the fixed ends 122 of the multiple support legs 120 are fitted into the mounting groove 330 (as shown in Figure 1), so that the lamp housing 310 is latched to the bottom of the support end 101. The latching of the lighting device 10 with the support end 101 (including the multiple fixed ends 122) through the mounting groove 330 maintains the retracted posture of the entire lighting device 10 on the one hand, and prevents the multiple fixed ends 122 from spreading out relatively, thus maintaining the closed posture of the multiple support legs 120 on the other hand. When the lighting device 10 is in the retracted state, it is not easy for the user to unfold it during use. Referring to Figure 7, each support leg 120 has a magnet 123 at its fixed end 122. The fixed end 122 can be magnetically attracted to the lamp head 300 by the magnet 123, so that the lamp head 300 is fastened to the bottom of the support end 101. That is, it is fastened to multiple fixed ends 122 to maintain the closed state of multiple support legs 120. It should be understood that, as mentioned above, fastening refers to a tight fit. In this embodiment, the lamp head 300 is fastened to the support end 101 by the mounting groove 330 or the magnet 123, or by the combined action of the mounting groove 330 and the magnet 123. In other embodiments of this application, the lamp housing 310 does not need to be provided with the mounting groove 330. The lamp head 300 can also be fastened to the support end 101 by providing suitable buckles, hooks, Velcro, magnets, etc. on the fastening surface of the lamp housing 310 and the bottom of the support end 101.

[0051] This invention provides a lighting device 10, comprising three parts: a support rod 100, a movable rod 200, and a lamp holder 300. The support rod 100 has a supporting end 101 and a mounting end 102. One end of the movable rod 200 is rotatably connected to the mounting end 102, and the other end is connected to the lamp holder 300. The movable rod 200 can rotate relative to the supporting end 101 until it is parallel to the support rod 100. At this time, the lamp holder 300 can be tightly fastened to the supporting end 101 to complete the folding and storage of the entire lighting device 10, while maintaining the parallel and close posture of the movable rod 200 and the support rod 100. The support rod 100 and the movable rod 200 do not interfere with the lamp holder 300 during relative rotation. The storage process of the lighting device 10 of this invention is convenient and simple. In its folded state, the lighting device 10 allows the user to hold both the support rod 100 and the movable rod 200 to use it as a flashlight or floodlight. When the lighting device 10 is not folded, the support rod 100 supports it on a support surface, allowing it to be used as a table lamp. Therefore, the lighting device 10 provided by this invention not only facilitates folding and carrying for the user, but also provides different lighting functions in different states, enhancing its practicality and multifunctionality. Furthermore, the rotatable connection between the support rod 100 and the movable rod 200 allows for changing the lighting orientation of the lamp head 300, adapting to various lighting needs. Finally, when folded, the lamp head 300 is tightly fastened to the support end 101. The support rod 100, movable rod 200, and lamp head 300 are connected end-to-end to form a closed frame structure, significantly improving the stability of the entire lighting device 10 in its folded state, reducing the wobbling of the lamp head 300 due to external forces, and protecting the lamp head 300.

[0052] Preferably, in this embodiment, referring to Figures 8 and 9, the lamp head 300 can rotate circumferentially around the first pivot 410 along the second connecting end 202, and the lamp head 300 can pitch and swing around the second pivot 420 along the axial direction of the second connecting end 202. The first pivot 410 and the second pivot 420 are perpendicular to each other, and the second pivot 420 is perpendicular to the axial direction of the second connecting end 202. The first pivot 410 and the second pivot 420 form a T-shaped shaft. The lamp head 300 is rotatably connected to the second connecting end 202 of the movable rod 200 through the T-shaped shaft. This design allows for flexible changes in the illumination orientation of the lamp head 300. It should be understood that the first pivot 410 and the second pivot 420 can be the aforementioned T-shaped shaft, in which case the first pivot 410 and the second pivot 420 should be understood as solid shafts. In other embodiments, the first rotating shaft 410 and the second rotating shaft 420 can also be virtual shafts. A "virtual shaft" is an axis that does not exist but is artificially defined in order to determine the rotation direction. For example, in this case, the lamp head 300 is connected to the movable rod 200 through a universal ball.

[0053] Preferably, in this embodiment, referring to Figures 10 and 11, the lamp housing 310 has a first end face 311 and a second end face 312 facing each other. The light source 320 includes two lighting lamps: a floodlight 321 and a spotlight 322. The mounting groove 330 includes a first mounting groove 331 and a second mounting groove 332. The floodlight 321 is disposed inside the lamp housing 310, and the light from the floodlight 321 is emitted through the first end face 311. The first mounting groove 331 is disposed on the first end face 311. The spotlight 322 is disposed inside the lamp housing 310, and the light from the spotlight 322 is emitted through the second end face 312. The second mounting groove 332 is disposed on the second end face 312.

[0054] Referring to Figures 5 and 10, when the lamp housing 310 is fastened to the bottom of the support end 101, the user can selectively face either the first end face 311 or the second end face 312 toward the support end 101 by relying on the circumferential rotation and pitch swing of the lamp head 300 relative to the movable rod 200. Correspondingly, the multiple fixed ends 122 can also be selectively fitted into either the first mounting groove 331 or the second mounting groove 332. Similarly, when the first end face 311 faces the support end 101, multiple fixed ends 122 are fitted into the first mounting groove 331. At this time, the second end face 312 is exposed away from the first end face 311. The light emitted by the floodlight 321 is blocked and hidden by the bottom of the support end 101, while the light emitted by the spotlight 322 shines through the second end face 312 and shines out, thus enabling the lighting device 10 to achieve the function of spotlight illumination. When the second end face 312 faces the support end 101, multiple fixed ends 122 are fitted into the second mounting groove 332. At this time, the first end face 311 is exposed away from the second end face 312.

[0055] It should be understood that in other embodiments of this application, firstly, the number of light source 320 and mounting slot 330 is not limited. Specifically, the lamp head 300 is fixedly connected to the movable rod 200, and the lamp housing 310 is only fastened to the support end 101 on one side. At this time, the mounting slot 330 is also only set in one location, and the light source 320 is set in one location. The light from the light source 320 can still selectively be emitted from the first end face 311 and the second end face 312. The first end face 311 is defined to have a mounting slot 330 and be fastened to the support end 101. The light from the light source 320 is emitted from the first end face 311. When the lighting device 10 is in its retracted state, the first end face 311, as the light-emitting surface, is hidden and protected, thus protecting the light source 320. The light from the light source 320 is emitted from the second end face 312. When the lighting device 10 is in its retracted state, the second end face 312, as the light-emitting surface, is exposed. At this time, the user holds the lighting device 10 for illumination, thus realizing the flashlight function of the lighting device 10. Furthermore, the floodlight 321 is defined as the first lighting lamp, and the spotlight 322 as the second lighting lamp. In this embodiment, the first and second lighting lamps are two different types of lighting lamps, realizing the multi-functionality of the lighting device 10. However, in other embodiments, the first and second lighting lamps can also be other types of lighting lamps, or even the same type of lighting lamp. The lighting function here is distinguished according to the light-emitting parameters of the lighting lamp, which include, but are not limited to, at least one of luminous intensity, luminous flux, illuminance, brightness, luminous efficacy, and color temperature.

[0056] Preferably, in this embodiment, the bottom walls of the first mounting groove 331 and the second mounting groove 332 are made of a light-transmitting material. Therefore, the light from the floodlight 321 is emitted through the bottom wall of the first mounting groove 331, and the light from the spotlight 322 is emitted through the bottom wall of the second mounting groove 332. It should be understood that in other embodiments of this application, when the bottom walls of the first mounting groove 331 and the second mounting groove 332 are opaque, and the floodlight 321 is directly embedded in and exposed in the first mounting groove 331, or the spotlight 322 is directly embedded in and exposed in the second mounting groove 332, the light from the floodlight 321 can also be emitted from the first end face 311, and the light from the spotlight 322 can also be emitted from the second end face 312. That is, in this application, whether the bottom walls of the first mounting groove 331 and the second mounting groove 332 are light-transmitting is not limited.

[0057] Preferably, in this embodiment, referring to Figures 12 and 13, the movable rod 200 rotates relative to the support rod 100 around the third pivot 430. The first connecting end 201 is connected to an adapter 230, which is circumferentially limited to the fixed rod 210. The mounting end 102 has a first lug 131 and a second lug 132 protruding from its side, spaced apart and opposite to each other. The third pivot 430 passes through the first lug 131, the adapter 230, and the second lug 132 sequentially along its axial direction to achieve a rotatable connection between the first connecting end 201 and the mounting end 102. A clearance area 133 is formed between the first lug 131 and the second lug 132. When the first connecting end 201 rotates relative to the mounting end 102, the clearance area 133 allows the adapter 230 to rotate. For ease of connection, in this embodiment, one end of the adapter 230 is cylindrical and sleeved onto the fixing rod 210, while the other end is flat and has an adapter hole for the third rotating shaft 430 to pass through. It should be understood that in other embodiments, the shape of the adapter 230 is not limited; it only needs to be able to connect one end to the fixing rod 210 and allow the third rotating shaft 430 to pass through at the other end. It should be understood that the adapter 230 is rotatably connected to the first lug 131 and the second lug 132 via the third rotating shaft 430, thereby realizing the rotatable connection of the first connecting end 201 to the mounting end 102. In other embodiments, firstly, the adapter 230 can be connected to the mounting end 102, and the first lug 131 and the second lug 132 can protrude and be formed at intervals on the side periphery of the first connecting end 201. The third rotating shaft 430 can still sequentially pass through the first lug 131, the adapter 230 and the second lug 132 along its axial direction to realize the rotatable connection between the first connecting end 201 and the mounting end 102. Secondly, in other embodiments, even without the first lug 131, the adapter 230, and the second lug 132, a slot or hole can be made in the mounting end 102 or the first connecting end 201 so that the third rotating shaft 430 passes through the first connecting end 201 and the mounting end 102. This allows the first connecting end 201 to be rotatably connected to the mounting end 102, enabling the movable rod 200 to rotate and swing relative to the support rod 100. In other words, in this application, the rotatable connection method between the first connecting end 201 and the mounting end 102 is not limited.

[0058] Referring to Figure 14, the lamp holder 300 requires a power source for illumination. Therefore, this application also includes a battery 500 and a conductive wire 600. The battery 500 provides power and is built into the support rod 100. The conductive wire 600 is built into the movable rod 200 and the support rod 100. The two ends of the conductive wire 600 are electrically connected to the lamp source 320 and the battery 500, respectively. Therefore, the lamp source 320 obtains power from the battery 500 through the conductive wire 600, thus achieving the lighting function. The design of the lamp source 320 being electrically connected to the battery 500 through the conductive wire 600 ensures uniform current transmission and good electrical contact. Here, the battery 500 can be a dry cell battery, which needs to be replaced when the power is depleted; or it can be a rechargeable battery, which can be recharged and reused by an external power source. It should be understood that in other embodiments, the power supply component can be directly designed inside the light source 320, so the lighting device 10 does not need to be equipped with an additional battery 500; the battery 500 can be directly installed in the light source 320 and electrically contact the light source 320 to provide power to the light source 320, so the lighting device 10 does not need to be equipped with an additional conductive wire 600.
