[0002] Generally, as a lighting appliance, a lighting device can switch between a folded state and an unfolded state for its multiple support legs. In the folded state, a user can hold the lighting device for lighting use. In the unfolded state, the user can place the lighting device on a table for lighting use. However, for a traditional lighting device, after the light-emitting component of the lighting device is retracted, it cannot be stably maintained in the retracted state, and the light-emitting component is prone to shaking under the influence of external forces, leading to risks such as damage and poor contact. Summary of the Utility Model

[0003] The utility model aims to provide a lighting device to solve the technical problem that the lighting component of a traditional lighting device cannot be stably maintained in the retracted state after being retracted, and the light-emitting component is prone to shaking under the influence of external forces, leading to risks such as damage and poor contact.

[0004] To solve the above technical problem, the utility model adopts the following technical solutions:

[0005] A lighting device, comprising:

[0006] A support rod having an installation end and a support end opposite to each other along its axial direction;

[0007] A movable rod having a first connection end and a second connection end opposite to each other along its axial direction. The first connection end is rotatably connected to the installation end. When the first connection end rotates relative to the installation end, the included angle between the movable rod and the support rod changes, and the movable rod can be flipped to be juxtaposed and close to the support rod;

[0008] A lamp head connected to the second connection end. The lamp head includes a lamp housing and a light source connected to each other. The lamp housing can be buckled to the support end when the movable rod and the support rod are in a juxtaposed and close posture.

[0009] In one embodiment, the movable rod includes a fixed rod and a telescopic rod. The first connection end of the fixed rod is rotatably connected to the installation end. The second connection end of the telescopic rod is connected to the lamp housing. The telescopic rod is movably sleeved on the fixed rod so that the movable rod can be extended or shortened. When the movable rod and the support rod are in a juxtaposed and close posture, the lamp housing can be buckled to the bottom of the support end by shortening the movable rod.

[0010] In one embodiment, the lamp head is rotatably connected to the second connection end to achieve the flipping of the lamp head. When the movable rod and the support rod are in a side-by-side and close-together posture, the lamp housing can be buckled to the bottom of the support end by rotating the lamp head.

[0011] In one embodiment, the support end includes a plurality of legs. Each leg has a rotating end and a fixed end that are oppositely arranged along its axial direction. The rotating end is rotatably connected to the mounting end. When the rotating end rotates relative to the mounting end and flips towards the outside of the support rod, the plurality of fixed ends can be switched from a closed state where they are close to each other to a supporting state where they are away from each other; when the plurality of fixed ends are in the closed state where they are close to each other, the lamp housing can be buckled to the bottoms of the plurality of fixed ends simultaneously when the movable rod and the support rod are in a side-by-side and close-together posture.

[0012] In one embodiment, the lamp housing is provided with a mounting groove, and the bottoms of the plurality of fixed ends can be simultaneously fitted into the mounting groove to be buckled to the lamp housing.

[0013] In one embodiment, a magnet is provided at the fixed end of each leg, and the fixed end can be magnetically attracted to the lamp head through the magnet.

[0014] In one embodiment, the lamp head can rotate around a first rotation axis along the circumferential direction of the second connection end, and the lamp head can also swing in a pitching manner around a second rotation axis along the axial direction of the second connection end. The first rotation axis is not only parallel to the axial direction of the second connection end, but also perpendicular to the second rotation axis; the lamp housing has a first end face and a second end face that are oppositely arranged. Depending on the circumferential rotation and pitching swing of the lamp head, the lamp head can be buckled to the support end, and the lamp housing can selectively make the first end face face the mounting end or make the second end face face the mounting end; the light source includes a first illuminating lamp, and the light of the first illuminating lamp is emitted through the first end face.

[0015] In one embodiment, the light source further includes a second illuminating lamp disposed inside the lamp housing, and the light of the second illuminating lamp is emitted through the second end face;

[0016] Wherein, the light-emitting parameters of the first illuminating lamp are different from those of the second illuminating lamp, and the light-emitting parameters include at least one of luminous intensity, luminous flux, illuminance, brightness, luminous efficacy, and color temperature.

[0017] In one embodiment, the first illuminating lamp is a spotlight, and the second illuminating lamp is a floodlight.

[0018] In one embodiment, mounting grooves are provided on both the first end face and the second end face. The bottom wall of the mounting groove is light-transmissive, and the light rays of the first lighting lamp and the second lighting lamp are both emitted through the bottom wall of the mounting groove. When the lamp housing is buckled to the support end, the bottom of the support end is fitted into the mounting groove.

[0019] In one embodiment, the movable rod can rotate circumferentially around the central axis of the support rod. After the movable rod swings circumferentially relative to the support rod to any angular orientation, the movable rod continues to rotate relative to the support rod until it is juxtaposed and close to the support rod, and the lamp head is buckled to the support end.

[0020] In one embodiment, the movable rod rotates relative to the support rod around a third rotating shaft. One of the first connection end and the mounting end is connected with an adapter, and the other has spaced and opposite first lug and second lug protruding from the side circumference. The third rotating shaft sequentially passes through the first lug, the adapter and the second lug. An avoidance area is formed between the first lug and the second lug for the adapter to flip and move.

[0021] In one embodiment, the lighting device further includes a battery and a wire. The battery is arranged in the support rod, the wire is arranged in the movable rod and the support rod, and the light source is electrically connected to the light source through the wire.

[0022] In one embodiment, the lamp head is detachably connected to the movable rod.

[0023] From the above technical solutions, it can be seen that the embodiments of the present utility model have at least the following advantages and positive effects:

[0024] The present utility model provides a lighting device. The movable rod can rotate relative to the support end until the movable rod and the support rod are arranged side by side and close to each other. At this time, the lamp head can also be tightly fastened to the support end to complete the folding and storage of the entire lighting device, and maintain the posture of the movable rod and the support rod being arranged side by side and close to each other. During the relative rotation of the support rod and the movable rod, the lamp head will not be interfered. The operation of the lighting device of the present utility model during the storage process is convenient and simple. When the lighting device is in the folded and stored state, the user holds the support rod and the movable rod simultaneously to use it as a flashlight or a floodlight; when the lighting device is not stored, the lighting device as a whole has a long rod-shaped structure, and the lamp head is far from the support end. The user can hold the support end by hand and use the lighting device as a detection lamp, or support the support rod on a support surface and use the lighting device as a table lamp. Therefore, on the one hand, the lighting device provided by the present utility model is not only convenient for folding, storing and carrying, but on the other hand, the lighting device realizes different lighting functions in different states, enhancing the practicability and multi-functionality of the lighting device. Moreover, since the support rod and the movable rod are rotatably connected, the lighting direction of the lamp head can be changed to meet more lighting needs of the user. Finally, after the lighting device of the present utility model is stored, the lamp head is tightly fastened to the support end. In this solution, the support rod, the movable rod and the lamp head 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 influence of external forces on the lamp head and prevent it from shaking, playing a role in protecting the lamp head.

[0042] Typical implementation modes reflecting the features and advantages of the present utility model will be described in detail in the following description. It should be understood that the present utility model can have various changes in different implementation modes, all of which do not depart from the scope of the present utility model, and the descriptions and illustrations therein are essentially for illustrative purposes and not for limiting the present utility model.

[0043] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0044] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0045] With reference to Figure 1 and Figure 2 , the present application provides a lighting device 10 that is convenient for folding and storage, and the lighting device 10 can be switched between an unfolded state and a stored state. Figure 1The lighting device 10 is shown in the storage state. At this time, the lighting device 10 can be held by the user and carried around to provide lighting functions. For example, the user can hold the lighting device to obtain lighting light, which is convenient for the user to carry out activities at night. At the same time, when the lighting device 10 is in the storage state, the volume and space occupied by the lighting device 10 are small, which is convenient for the user to store and carry around. Figure 2 The lighting device 10 is shown in the unfolded state. The lighting device 10 in the unfolded state has a higher illumination height and a larger illumination range. At this time, the user can hold it with bare hands to provide illumination for a large range of mobile space when camping outdoors, and use it as a mobile street light or detection light when traveling at night, which is not only convenient for guiding lighting, but also convenient for users to observe the surrounding environment. Or, refer to Figure 3 In other usage scenarios, the lighting device 10 can be further unfolded into a bracket state, so that the lighting device 10 can be placed on a flat or uneven support surface to provide lighting function. For example, reading a book or using a computer at home at night requires appropriate lighting to protect the eyes from strong light damage. At this time, the lighting device 10 can be supported on a desktop and used as a desk lamp. It should be understood that in the present application, the lighting device 10 does not necessarily have to be able to be unfolded into a bracket state, and it is only necessary to meet the requirement that the lighting device can be stored and folded. In addition, under the premise that the supporting body of the lighting device 10 is strong enough, the user can also directly support the unfolded lighting device 10 on the supporting surface.

[0046] Combined with reference Figure 1 and Figure 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 pitches and swings relative to the support rod 100, so that the entire lighting device 10 can be switched freely between the unfolded state and the folded state.

[0047] Specifically, the support rod 100, as the support main body, has opposite support ends 101 and mounting ends 102. When the lighting device 10 is in the unfolded state, the support rod 100 can support the lighting device 10 on the support surface; the movable rod 200 has opposite first connection ends 201 and second connection ends 202. The first connection end 201 is rotatably connected to the mounting end 102. When the first connection end 201 rotates relative to the mounting end 102, the included angle between the movable rod 200 and the support rod 100 changes, and the movable rod 200 can be flipped to be juxtaposed and close 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 is switched from the unfolded state to the stored state; the lamp head 300, as the lighting component of the lighting device 10, emits lighting light to provide a light source for the user. The lamp head 300 is connected to the second connection end 202. The lamp head 300 includes a lamp housing 310 and a light source 320 provided in the lamp housing 310. The lamp housing 310 protects the light source 320 from being knocked by the outside. As Figure 1 shown, 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 juxtaposed and close posture, the lamp housing 310 is buckled to the support end 101 of the support rod 100. Here, buckling means that the two are closely combined and can be realized by means such as buckles, hooks, adhesives, magnetic attraction, etc.; the lamp housing 310 is buckled to the support end 101, including but not limited to that the lamp housing 310 can be buckled to the side circumference, edge, bottom of the support end 101.

[0048] Specifically, refer to Figure 3, when using the lighting device 10, the user can apply an external force to the support rod 100, and under the action of the external force, the support rod 100 is unfolded. When the support rod 100 is in the unfolded state, the support rod 100 has a tripod structure. At this time, the lighting device 10 in the unfolded state can be placed on the flat or uneven support surface described above. The lighting device 10 provides a lighting function as a table lamp. At this time, the support rod 100 plays a role in supporting and fixing the movable rod 200 and the lamp head 300. When the lighting device 10 is placed on the support surface through the tripod structure, the movable rod 200 can swing up and down along the axial direction of the support rod 100 to change the lighting height. At the same time, 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 angular orientation, the movable rod 200 is folded in a pitching manner, and the lamp head 300 provided at the free end of the movable rod 200 can be directly buckled to the support end 101. This means that in the actual use process, no matter how the lighting angle orientation of the lamp head 300 is adjusted, the lamp head 300 can be directly buckled to the support end 101 by pitching and swinging the movable rod 200, without necessarily swinging the movable rod 200 to a fixed orientation in advance. This greatly simplifies the folding operation process of the lighting device 10 and shortens the time for the user to complete the folding and buckling of the lighting device 10. In addition, it should be explained that in other embodiments, the movable rod 200 can also be set to be non-circumferentially swingable relative to the support rod 100, that is, the circumferential angle adjustment of the movable rod 200 is not necessary.

[0049] More specifically, in this embodiment, with reference to Figure 2 and Figure 3 , the support rod 100 includes a connected rod body 110 and multiple legs 120. The relative two ends of the rod body 110 along its axial direction respectively correspond to the support end 101 and the mounting end 102 mentioned above. The multiple legs 120 can be switched between a folded state and an unfolded state as support components. Each leg 120 has a relative rotating end 121 and a fixed end 122. The rotating end 121 is rotatably connected to the side circumference 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 state of approaching and closing to a state of moving away from each other for support. The multiple legs 120 are switched from the folded state ( Figure 2 shown) to the support state ( Figure 3 shown, which is the triangular support frame state mentioned above). When the multiple legs 120 are in the folded state, the multiple legs 120 are arranged side by side against the side circumference of the rod body 110 and surround it. In this state, the user can also continue to operate to flip and fold the movable rod 200 to a posture where the movable rod 200 is arranged side by side and close to the support rod 100, that is, as shown in Figure 1In the stored state of the lighting device 10 shown, the user can hold the support rod 100 and the movable rod 200 simultaneously and use the lighting device 10 as a flashlight for lighting.

[0050] It should be understood that, first, multiple legs 120 enhance the supporting function of the support rod 100. In other embodiments, when the radial dimension of the support rod 100 is large enough, the end face area of the support end 101 is large and flat. At this time, the support rod 100 can directly support on the support surface through the end face of the support end 101, and there is no need to additionally provide multiple legs 120 to enable the support rod 100 to achieve the supporting function of the support frame. Second, the deployment method of the multiple legs 120 can be that the legs 120 in this embodiment flip and turn outwards relative to the outer wall of the rod body 110 for deployment. In other embodiments, the multiple legs 120 can also rotate circumferentially along the rod body 110 for deployment, as long as it is satisfied that the multiple legs 120 can be switched between the folded state and the supporting state.

[0051] Preferably, the outer shape structure of the support rod 100 is cylindrical. On the one hand, when the lighting device 10 is in the stored state, it provides a better holding feel for the user, so that the lighting device 10 can be carried around for lighting use. On the other hand, it is easier to process. It should be understood that in other embodiments, without considering the holding feel and ease of processing, the outer shape structure of the support rod 100 can also be an ellipsoid, a triangular prism, a quadrangular prism, etc. That is, the present application does not make any limitation on the outer shape of the support rod 100.

[0052] Preferably, in this embodiment, with reference to Figure 3 and Figure 4, the movable rod 200 includes a connected fixed rod 210 and a telescopic rod 220. The fixed rod 210 is rotatably connected to the mounting end 102 at the first connection end 201. The telescopic rod 220 is connected to the lamp housing 310 at the second connection end 202. The telescopic rod 220 is movably sleeved on the fixed rod 210. The telescopic rod 220 can reciprocate axially relative to the fixed rod 210, so that the movable rod 200 can extend or contract to change the length dimension, and at the same time change the distance between the lamp head 300 and the support rod 100. Here, it should be understood that, first, the fixed rod 210 and the telescopic rod 220 are in a relative sense, representing two pipe fittings that can be connected end to end and can telescopically relative to each other; that is, in other embodiments of the present application, the connection situation can also be as follows: the fixed rod 210 is connected to the lamp housing 310 at the second connection end 202, and the telescopic rod 220 is rotatably connected to the mounting end 102 at the first connection end 201. Second, the number of telescopic rods 220 can be one or more. The more the number, the larger the telescopic length range; the telescopic rods 220 are generally sleeved in sequence according to the radial dimension of the pipe fittings. The pipe fitting with a small size can be telescopically hidden or extended out of the pipe fitting with a large size. In this embodiment, the number of telescopic rods 220 is multiple, and the radial dimension decreases sequentially from inside to outside with the sleeve and is smaller than the radial dimension of the fixed rod 210, which enables the telescopic rods 220 to be hidden inside the fixed rod 210.

[0053] With reference to Figure 3 and Figure 4 , when the lighting device 10 is in the unfolded state, with the included angle between the axis of the movable rod 200 and the support rod 100 fixed, the movable rod 200 can change its length by telescoping, thereby changing the distance between the first connection end 201 and the second connection end 202, and thus changing the distance between the support rod 100 and the lamp head 300, so as to change the lighting distance and azimuth of the lamp head 300.

[0054] With reference to Figure 1 and Figure 5 , when the lighting device 10 is in the storage state, the lamp head 300 approaches or moves away from the support end 101 as the movable rod 200 telescopes, and finally the lamp head 300 can be buckled to the bottom of the support end 101. At this time, the fixed ends 122 of the plurality of legs 120 are simultaneously buckled to the bottom of the support end 101.

[0055] Preferably, with reference to Figure 1 and Figure 6, in this embodiment, the lamp head 300 is rotatably connected to the second connection end 202 to realize the flipping of the lamp head 300. The lamp head 300 swings along the axial direction of the movable rod 200 to realize the flipping relative to the second connection end 202. When the movable rod 200 and the support rod 100 are in a side-by-side and close-together posture, the flipping of the lamp housing 310 drives the lamp head 300 to rotate synchronously to be buckled to the bottom of the support end 101. At this time, the fixed ends 122 of the plurality of legs 120 are simultaneously buckled to the bottom of the support end 101.

[0056] With reference to Figure 5 and Figure 6 , the lamp head 300 in this embodiment can not only approach or move away from the support rod 100 through the movable rod 200, but also swing relative to the movable rod 200 by being rotatably connected to the movable rod 200, so as to flexibly change the lighting orientation. It should be understood that in other embodiments of the present application, the lamp head 300 is detachably connected to the movable rod 200. After the user detaches the lamp head 300 from the second connection end 202 according to the required lighting orientation, the movable rod 200 can be rotated and telescoped at will. After adjusting to the target lighting orientation, the user then installs the lamp head 300 on the second connection end 202; on the other hand, 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 the usage needs. Different models of lamp heads 300 can be different in shape, light-emitting color, light-emitting power, etc. Of course, in other embodiments, the lamp head 300 is non-detachably connected to the second connection end 202, and the user can also adjust the lighting orientation of the lamp head 300 by rotating and telescoping the lamp. Therefore, in the present application, whether the lamp head 300 is detachably connected to the second connection end 202 is not limited.

[0057] 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 connection end 201 of the movable rod 200 is flipped relative to the installation end 102 to the posture where the movable rod 200 and the support rod 100 are side by side and close together, the second connection end 202 of the movable rod 200 approaches or moves away from the support end 101 by the telescoping of the movable rod 200, and at the same time drives the lamp head 300 to approach or move away from the support end 101. The buckling surface of the lamp head 300 faces the support end 101. Therefore, the lamp head 300 can be buckled to the bottom of the support end 101 only by the telescoping of the movable rod 200; on the other hand, the movable rod 200 cannot be telescoped. When the first connection end 201 of the movable rod 200 is flipped relative to the installation end 102 to the posture where the movable rod 200 and the support rod 100 are side by side and close together, at this time, the lamp head 300 can be buckled to the bottom of the support end 101 only by flipping the lamp head 300, and at the same time, the fixed ends 122 of the plurality of legs 120 are simultaneously buckled to the bottom of the support end 101.

[0058] Preferably, with reference to Figure 6 orFigure 7 , an installation groove 330 is formed on the fastening surface of the lamp housing 310, and the fixed ends 122 of multiple legs 120 are fitted into the installation groove 330 (as Figure 1 shown), so that the lamp housing 310 is fastened to the bottom of the support end 101. Through the fastening of the installation groove 330 and the support end 101 (including multiple fixed ends 122) of the lighting device 10, on the one hand, the storage posture of the entire lighting device 10 is maintained, and on the other hand, it prevents the multiple fixed ends 122 from spreading relatively away from each other and maintains the closed posture of the multiple legs 120. When the lighting device 10 is in the storage state, during the use process when the user holds the lighting device 10, the lighting device 10 is not easily unfolded. Refer to Figure 7 , a magnet 123 is provided at the fixed end 122 of each leg 120, and the fixed end 122 can be magnetically attracted to the lamp head 300 through the magnet 123, so as to realize the fastening of the lamp head 300 to the bottom of the support end 101, that is, fastening to multiple fixed ends 122 to maintain the closed state of the multiple legs 120. It should be understood that the fastening mentioned above refers to a tight combination. In this embodiment, the lamp head 300 is fastened to the support end 101 through the installation groove 330 or the magnet 123, or the lamp head 300 is fastened to the support end 101 through the combined action of the installation groove 330 and the magnet 123. In other embodiments of the present application, the lamp housing 310 does not need to be provided with the installation groove 330, and the lamp head 300 can also be fastened to the support end 101 by setting matching buckles, hooks, Velcro, magnets, etc. on the fastening surface of the lamp housing 310 and the bottom of the support end 101.

[0059] The present utility model provides a lighting device 10, which includes three parts: a support rod 100, a movable rod 200, and a lamp head 300. The support rod 100 has opposite support end 101 and 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 head 300. The movable rod 200 can rotate relative to the support end 101 until the movable rod 200 and the support rod 100 are arranged side by side and close to each other. At this time, the lamp head 300 can be tightly buckled to the support end 101 at the same time to complete the folding and storage of the entire lighting device 10, and maintain the posture of the movable rod 200 and the support rod 100 being arranged side by side and close to each other. The support rod 100 and the movable rod 200 will not interfere with the lamp head 300 during the relative rotation process. The operation of the lighting device 10 of the present utility model during the storage process is convenient and simple. When the lighting device 10 is in the folded and stored state, the user holds the support rod 100 and the movable rod 200 at the same time to use it as a flashlight or a floodlight; when the lighting device 10 is not stored, the support rod 100 can support the lighting device 10 on the support surface, and the user can use it as a table lamp. Therefore, on the one hand, the lighting device 10 provided by the present utility model is not only convenient for the user to fold, store and carry, but on the other hand, the lighting device 10 realizes different lighting functions in different states, enhancing the practicability and multi-functionality of the lighting device 10. Moreover, since the support rod 100 and the movable rod 200 are rotatably connected, the lighting orientation of the lamp head 300 can be changed to meet more lighting needs of the user. Finally, after the lighting device 10 of the present utility model is stored, the lamp head 300 is tightly buckled to the support end 101. In the present solution, the support rod 100, the movable rod 200, and the lamp head 300 are connected end to end to form a closed frame structure, greatly improving the stability of the entire lighting device 10 in the stored state, reducing the shaking of the lamp head 300 affected by external forces, and playing a role in protecting the lamp head 300.

[0060] Preferably, in this embodiment, with reference to Figure 8 and Figure 9 , the lamp head 300 can rotate around the first rotation axis 410 along the circumferential direction of the second connection end 202, and the lamp head 300 can swing up and down along the axial direction of the second connection end 202 around the second rotation axis 420. The first rotation axis 410 and the second rotation axis 420 are perpendicular to each other. The second rotation axis 420 is perpendicular to the axial direction of the second connection end 202. The first rotation axis 410 and the second rotation axis 420 form a T-shaped axis. The lamp head 300 is rotatably connected to the second connection end 202 of the movable rod 200 through the T-shaped axis. The above design can flexibly change the lighting orientation of the lamp head 300. It should be understood that the first rotation axis 410 and the second rotation axis 420 can be the above-mentioned T-shaped axis. At this time, the first rotation axis 410 and the second rotation axis 420 should be understood as real axes. In other embodiments, the first rotation axis 410 and the second rotation axis 420 can also be virtual axes. The so-called "virtual axis" is an axis that does not exist and is artificially defined to facilitate the determination of the rotation orientation. For example, at this time, the lamp head 300 is connected to the movable rod 200 through a universal ball.

[0061] Preferably, in this embodiment, with reference to Figure 10 and Figure 11 , the lamp housing 310 has opposite first and second end faces 311 and 312. The light source 320 includes two lighting lamps, namely a floodlight 321 and a spotlight 322. The mounting grooves 330 include a first mounting groove 331 and a second mounting groove 332. The floodlight 321 is disposed inside the lamp housing 310, and the light of 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 of the spotlight 322 is emitted through the second end face 312. The second mounting groove 332 is disposed on the second end face 312.

[0062] With reference to Figure 5 and Figure 10 , when the lamp housing 310 is buckled to the bottom of the support end 101, the user can selectively orient one of the first end face 311 and the second end face 312 towards the support end 101 by relying on the circumferential rotation and pitching swing of the lamp head 300 relative to the movable rod 200. Correspondingly, the plurality of fixed ends 122 can also be selectively fitted into one of the first mounting groove 331 and the second mounting groove 332. Similarly, when the first end face 311 faces the mounting end 102, the plurality of fixed ends 122 are fitted into the first mounting groove 331. At this time, the second end face 312 faces away from the first end face 311 and is exposed. The light emitted by the floodlight 321 is blocked by the bottom of the support end 101 and hidden, and the light emitted by the spotlight 322 is emitted through the second end face 312 and exposed, so that the lighting device 10 realizes the spotlight lighting function. When the second end face 312 faces the support end 101, the plurality of fixed ends 122 are fitted into the second mounting groove 332. At this time, the first end face 311 faces away from the second end face 312 and is exposed. The light emitted by the spotlight 322 is blocked by the bottom of the support end 101 and hidden, and the light emitted by the floodlight 321 is emitted through the first end face 311 and exposed, so that the lighting device 10 realizes the diffused light lighting function.

[0063] It should be understood that in other embodiments of the present application, first, in the present application, the set numbers of the light source 320 and the installation groove 330 are not limited. Specifically, the lamp head 300 is fixedly connected to the movable rod 200, and only one side of the lamp housing 310 is buckled to the installation end 102. At this time, only one installation groove 330 is correspondingly provided, and one light source 320 is provided. The light of the light source 320 can still selectively emit from the first end face 311 and the second end face 312. It is defined that the installation groove 330 is provided on the first end face 311 and is buckled to the support end 101. When the light of the light source 320 emits from the first end face 311, then in the storage state of the lighting device 10, the first end face 311 is hidden and protected as the light-emitting surface, thereby protecting the light source 320; when the light of the light source 320 emits from the second end face 312, then in the storage state of the lighting device 10, the second end face 312 is exposed as the light-emitting surface. At this time, the user holds the lighting device 10 for lighting use, thereby realizing the flashlight function of the lighting device 10. Secondly, it is defined that the floodlight 321 is the first lighting lamp and the spotlight 322 is the second lighting lamp. The first lighting lamp and the second lighting lamp in this embodiment are two lighting lamps with different functions, realizing the multi-functional lighting of the lighting device 10. However, in other embodiments, the first lighting lamp and the second lighting lamp can also be lighting lamps of other function types, or even lighting lamps of the same function type. The lighting functions here are distinguished according to the light-emitting parameters of the lighting lamps. The light-emitting parameters include at least one of, but are not limited to, luminous intensity, luminous flux, illuminance, brightness, luminous efficacy, and color temperature.

[0064] Preferably, in this embodiment, the bottom walls of the first installation groove 331 and the second installation groove 332 are made of light-transmitting materials. Therefore, the light of the floodlight 321 emits through the bottom wall of the first installation groove 331, and the light of the spotlight 322 emits through the bottom wall of the second installation groove 332. It should be understood that in other embodiments of the present application, when the bottom walls of the first installation groove 331 and the second installation groove 332 are not light-transmitting, when the floodlight 321 is directly embedded and exposed in the first installation groove 331, or the spotlight 322 is directly embedded and exposed in the second installation groove 332, the light of the floodlight 321 can also emit from the first end face 311, and the light of the spotlight 322 can also emit from the second end face 312. That is, in the present application, it is not limited whether the bottom walls of the first installation groove 331 and the second installation groove 332 are light-transmitting.

[0065] Preferably, in this embodiment, with reference to Figure 12 and Figure 13, the movable rod 200 rotates relative to the support rod 100 about the third rotating shaft 430. A transfer member 230 is connected to the first connection end 201. The transfer member 230 is circumferentially limited with the fixed rod 210. On the side circumference of the installation end 102, spaced and opposite first lug 131 and second lug 132 protrude. The third rotating shaft 430 sequentially passes through the first lug 131, the transfer member 230, and the second lug 132 along its axial direction to realize the rotational connection between the first connection end 201 and the installation end 102. An avoidance area 133 is formed between the first lug 131 and the second lug 132. When the first connection end 201 rotates relative to the installation end 102, the avoidance area 133 provides space for the transfer member 230 to flip and move. Here, for the convenience of connection, in this embodiment, one end of the transfer member 230 is in a circular tube shape and sleeved on the fixed rod 210, and the other end of the transfer member 230 is in a flat shape and provided with a transfer hole for the third rotating shaft 430 to pass through. It should be understood that in other embodiments, the shape of the transfer member 230 is not limited, as long as one end can be connected to the fixed rod 210 and the other end can provide a passage for the third rotating shaft 430. It should be understood that the transfer member 230 is rotationally connected to the first lug 131 and the second lug 132 through the third rotating shaft 430, thus realizing the rotational connection between the first connection end 201 and the installation end 102. In other embodiments, first, the transfer member 230 can be connected to the installation end 102, and the first lug 131 and the second lug 132 can protrude and be spaced on the side circumference of the first connection end 201. The third rotating shaft 430 can still sequentially pass through the first lug 131, the transfer member 230, and the second lug 132 along its axial direction to realize the rotational connection between the first connection end 201 and the installation end 102. Second, in other embodiments, even if the first lug 131, the transfer member 230, and the second lug 132 are not provided, by grooving and opening holes in the installation end 102 or the first connection end 201 such that the third rotating shaft 430 passes through the first connection end 201 and the installation end 102, the rotational connection between the first connection end 201 and the installation end 102 can also be realized, and the movable rod 200 can be flipped and swung relative to the support rod 100. That is, in this application, the rotational connection manner between the first connection end 201 and the installation end 102 is not limited.

[0066] Reference Figure 14, the lamp head 300 requires a power supply for lighting. 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 light source 320 and the battery 500 respectively. Therefore, the light source 320 is electrically connected to the battery 500 through the conductive wire 600 to obtain power and achieve the lighting function. With the design that the light source 320 is electrically connected to the battery 500 through the conductive wire 600, the current transmission is uniform and the electrical contact is good. Here, the battery 500 can be a dry battery and needs to be replaced when the power is exhausted; the battery 500 can also be a storage battery and can be recharged through an external power supply for repeated use. It should be understood that in other embodiments, a power supply component can be directly designed inside the light source 320. In this case, the lighting device 10 does not need to be additionally provided with a battery 500; the battery 500 can be directly disposed on the light source 320 and be in electrical contact with the light source 320 to provide power for the light source 320. In this way, the lighting device 10 does not need to be additionally provided with a conductive wire 600.
