[0002] Generally, as a lighting appliance, a lighting device with a bracket can be supported on a support surface to use the lighting function. According to the user's adaptation to more lighting usage scenarios, the lamp head needs to flexibly change the circumferential lighting orientation and lighting height. For example, Patent CN117346115A discloses a lighting device, which needs to rotate the lamp head itself to change the circumferential lighting orientation on the premise that the battery box and the bracket are relatively fixed; on the premise that the lamp head and the battery box are relatively fixed, the bracket slides relative to the battery box to change the up and down height. That is, the change of the up and down height and the circumferential orientation of the lamp head need to be operated independently, and the operations of adjusting the height and circumferential orientation of the lamp head are cumbersome and time-consuming. Summary of the Utility Model

Detailed implementation mode

[0035] 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.

[0036] 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, "a plurality of" means two or more unless otherwise specifically defined.

[0037] With reference to Figure 1 and Figure 2 , the present application provides a lighting device 10, and the lighting device 10 can be switched between a storage state, an unfolded state, and a bracket state. In this embodiment, Figure 1 It shows the lighting device 10 in the storage state. At this time, the lighting device 10 can be held by the user for carrying and provide a lighting function. For example, the user can obtain lighting light by holding the lighting device 10, which is convenient for the user to move at night. At the same time, when the lighting device 10 is in the storage state, the volume and occupied space of the lighting device 10 are small, thus facilitating storage and carrying around. Figure 2The diagram shows the lighting device 10 in the unfolded state. The lighting device 10 in the unfolded state has a higher lighting height and a larger angle lighting range. At this time, the user can hold it with bare hands to provide lighting for a large range of mobile space when camping outdoors. It can be used 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. Figure 3 As shown, in other usage scenarios, the user can further unfold the lighting device 10 into a stand state, so as to place the lighting device 10 on a flat or uneven support surface to provide lighting function. For example, when reading or using a computer at home at night, appropriate lighting is required to protect the eyes from strong light damage. At this time, the lighting device 10 can be supported on the desktop and used as a desk lamp. It should be understood that the lighting device 10 of the present application does not necessarily present Figure 1 The storage status shown and Figure 2 The unfolded state shown only requires that the lighting device 10 can present Figure 3 In the state of the bracket shown, the lighting device 10 is supported on a supporting surface to provide a lighting function. Moreover, the angle at which the bracket is unfolded can be changed, and the supporting height of the lighting device 10 also changes accordingly.

[0038] Combined with reference Figure 1 and Figure 2 The lighting device 10 of the present application includes a support rod 100, a movable rod 200 and a lamp head 300 connected in sequence. The movable rod 200 is movably connected to the support rod 100. The lamp head 300 serves as the lighting component of the lighting device 10 to emit lighting light to provide a light source for the user, and the lamp head 300 is connected to the free end of the movable rod 200 (the other end of the movable rod 200 relative to the support rod 100). The movable rod 200 moves relative to the support rod 100, so that the entire lighting device 10 can switch freely between the unfolded state and the folded state. Preferably, the movable rod 200 of this embodiment is rotatably connected to the outside of the support rod 100, and the movable rod 200 pitches and swings relative to the support rod 100 along the axial direction of the support rod 100 until the movable rod 200 and the support rod 100 are brought together side by side to realize the folding and storage of the entire lighting device 10. It should be understood that, in other embodiments, first, the lamp head 300 can be directly connected to the support rod 100 to form the lighting device 10. In this application, the presence or absence of the movable rod 200 is not limited. Secondly, in other embodiments, the pitch and tilt angles of the movable rod 200 relative to the support rod 100 are not limited. That is, the movable rod 200 may not necessarily swing to be side by side with the support rod 100 to achieve the folded state of the lighting device 10. Finally, in other embodiments, the movable rod 200 may not necessarily be able to pitch and tilt relative to the support rod 100. That is, in this application, whether the lighting device 10 can be folded and stored is not limited.

[0039] Specifically, in this embodiment, the support rod 100, as the support main body, has a support end 101 and a mounting end 102 that are opposite to each other along its axial direction. 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 a first connection end 201 and a second connection end 202 that are opposite to each other along its axial direction. The first connection end 201 is connected to the mounting end 102; the second connection end 202 is connected to the lamp head 300. Preferably, in this embodiment, 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. 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 the juxtaposed and close posture, the lamp head 300 is buckled to the support end 101. Here, buckling means that the two are closely combined, which can be realized by means of snap, hook, paste, magnetic attraction, etc.; the lamp head is buckled to the support end 101, including but not limited to that the lamp head 300 can be buckled to the side circumference, edge, bottom of the support end 101. It should be understood that in other embodiments, whether the lamp head 300 is buckled to the support end 101 is not limited.

[0040] In this embodiment, with reference to Figure 3 and Figure 4 , the support rod 100, as the support main body, includes a central axis 110 and a tripod 120. The opposite ends of the central axis 110 along its axial direction respectively correspond to the support end 101 and the mounting end 102 described above. The lamp head 300 is connected to the mounting end 102 through the movable rod 200. The lamp head 300 is installed and connected to the outside of the mounting end 102 of the central axis 110 and can be circumferentially limited (the circumferential limitation here means that the lamp head 300 cannot rotate relative to the mounting end 102 around the circumference of the central axis 110). The tripod 120 is connected to the outside of the central axis 110 and is in an unfolded support state to support the lighting device on the support surface. In this application, the unfolded tripod 120 can rotate circumferentially relative to the central axis 110, and the lamp head 300 rotates synchronously with the central axis 110 relative to the tripod 120 to change the circumferential lighting orientation of the lamp head 300; the tripod 120 can slide axially relative to the central axis 110, the unfolding angle of the tripod 120 changes, and the support height of the tripod 120 changes accordingly to change the lighting height of the lamp head 300.

[0041] Specifically, with reference to Figure 3 and Figure 4, the support rod 100 further includes a support plate 130, and the support plate 130 is rotationally connected to the support end 101 along the circumferential direction of the central axis 110. The tripod 120 includes a collar 121, a plurality of legs 122, and a plurality of support rods 123. The number of legs 122 and support rods 123 is the same and they correspond to each other one by one. The collar 121 is sleeved on the outside of the central axis 110 and can rotate along the circumferential direction of the central axis 110. The collar 121 is slidably connected to the central axis 110 along the axial direction of the central axis 110; each leg 122 has a first end 1221 and a second end 1222 that are opposite to each other along its axial direction. The first end 1221 is rotationally connected to the side circumference of the collar 121, and the second ends 1222 support against the support surface while being away from each other; the support rod 123 is connected between the support plate 130 and the leg 122. The support rod 123 has a third end 1231 and a fourth end 1232 that are opposite to each other along its axial direction. The third end 1231 is hinged (rotationally connected) to the inner side of the leg 122, and the fourth end 1232 is hinged (rotationally connected) to the side circumference of the support plate 130.

[0042] The above structure can realize the circumferential rotation and axial sliding of the tripod 120 relative to the central axis 110. The realization process is as follows: The collar 121 and the support plate 130 rotate synchronously relative to the central axis 110, driving the legs 122 and the support rods 123 to rotate synchronously relative to the central axis 110, so as to realize the circumferential rotation of the tripod 120 relative to the central axis 110; preferably, in this embodiment, refer to Figures 2 to 3 , the tripod 120 can switch from the closed state ( Figure 2 ) to the unfolded state ( Figure 3 ), and the collar 121 slides axially along the central axis 110 between the support end 101 and the mounting end 102. Specifically, when the collar 121 slides away from the mounting end 102, the first end 1221 flips towards the outside of the collar 121, and at the same time drives the plurality of second ends 1222 to switch from the closed state of being close to each other to the supporting state of being away from each other. Synchronously, the leg 122 drives the correspondingly connected third end 1231 to switch from the closed state of being close to each other to the supporting state of being away from each other, and the fourth end 1232 flips outwards relative to the support plate 130. In this way, the plurality of legs 122 and the plurality of support rods 123 both switch from the closed state ( Figure 2 ) to the supporting state ( Figure 3 ), so that the tripod 120 switches from the closed state to the unfolded state.

[0043] Preferably, in this embodiment, refer to Figure 3 , the collar 121 has a sleeve 1211 extending along the central axis 110. The sleeve 1211 is sleeved on the outer wall of the central axis 110 to more stably sleeve the tripod 120 on the outside of the central axis 110. Combining reference to Figure 5 and Figure 6, when the tripod 120 is in the folded state, the sleeve 1211 is sleeved on the mounting end 102, the support rods 123 are arranged side by side and stored in the support end 101, and the collar 121 and the support rods 123 protrude from the outer wall of the central axis 110 at intervals in the axial direction along the central axis 110. Preferably, in this embodiment, a storage groove 1223 is formed on the inner side of the leg 122. When the tripod 120 is in the folded state, the storage groove 1223 stores the collar 121 and the support rods 123. Such a design enables the central axis 110 and the tripod 120 to make the structure of the entire support rod 100 more compact in the folded state.

[0044] It should be understood that, first, in other embodiments, without considering the stability of the tripod 120 sleeved on the central axis 110, the sleeve 1211 part of the extended collar 121 may not be provided, and the tripod 120 may also be sleeved on the outer side of the central axis 110 through a simple collar 121; second, in other embodiments, when the tripod 120 is in the folded state, without considering the compactness of the storage structure of the support rod 100, the storage groove 1223 may not be formed on the inner side of the leg 122. Therefore, in this application, the setting or not of the sleeve 1211 and the storage groove 1223 is not limited.

[0045] Here, for the convenience of understanding, refer to Figure 3 , define the planar triangle formed by the leg 122, the corresponding connected support rod 123 and the central axis 110 as abc. During the reciprocating movement (sliding) of the collar 121 along the axial direction of the central axis 110, the sizes of the three interior angles of the triangle abc change accordingly. The three interior angles of the triangle abc correspond to the included angles between any two of the leg 122, the corresponding connected support rod 123 and the central axis 110. Here, the length extension direction of the central axis 110 remains unchanged (parallel to the height direction supported by the tripod 120), and the support height of the tripod 120 changes accordingly, that is, the rotatably connected leg 122 and support rod 123 can change the unfolding angle and support height of the tripod 120. When the tripod 120 is in the folded state ( Figure 2 as shown), the three interior angles of the triangle abc are all 0 degrees. At this time, multiple legs 122 and multiple support rods 123 are all in a side-by-side and close-together posture with the central axis. It should be understood that in other embodiments, during the sliding process of the collar 121, the three interior angles of the triangle abc cannot be reduced to 0 degrees, that is, the tripod 120 cannot be completely folded. That is, in this application, whether the tripod 120 is folded and stored is not limited, as long as the support height can be changed.

[0046] The present invention provides a lighting device, including a lamp head 300, a central axis 110 and a tripod 120. The lamp head 300 serves as a lighting body and is mounted and connected to one end (mounting end 102) of the central axis 110. The tripod 120 is sleeved on the central axis 110 to form a support frame to support the lighting device 10 on a support surface. Under the premise that the lamp head 300 and the central axis 110 are relatively fixed, the tripod 120 can not only slide up and down relative to the central axis 110 to change the lighting height of the lamp head 300, but also can rotate circumferentially relative to the central axis 110 to change the circumferential lighting orientation of the lamp head 300. Therefore, compared with the lighting device 10 disclosed in patent CN117346115A, for the lighting device 10 of the present application, the user only needs to operate the sliding and rotation of the tripod 120 relative to the central axis 110 to adjust the circumferential lighting orientation and lighting height of the lamp head 300 accordingly. That is, the user can hold the central axis with one hand and move the tripod 120 with the other hand to adjust the lighting height and lighting circumferential direction. This is ergonomically designed, greatly improves the convenience and practicality of the lighting device 10 itself, and enhances the user experience.

[0047] Preferably, in this application, reference is made to Figure 4 and Figure 7 The lighting device 10 also includes a power supply component 400. The central axis is provided with a mounting cavity 103. The power supply component 400 is arranged in the mounting cavity 103. The power supply component 400 includes a main board 410 and a power supply structure 420 provided on the main board 410. The main board 410 is electrically connected to the lamp head 300 through the power supply structure 420. The main board 410 and the power supply structure 420 of the present application can rotate circumferentially relative to the tripod 120 synchronously with the central axis 110. Therefore, the lamp head 300, the main board 410 and the power supply structure 420 can rotate synchronously with the central axis 110 relative to the tripod 120. This enhances the electrical contact stability of the entire lighting device 10 and extends the lighting life of the lighting device 10. It should be understood that in other embodiments of the present application, without considering the electrical contact stability, there is no limitation on whether the lamp head 300, the main board 410 and the power supply structure 420 rotate synchronously.

[0048] Preferably, in this embodiment, in combination with reference Figure 4 and Figure 8, the central axis 110 includes a tube body 111, a tube cap 112 and a nut 113. The opposite ends of the tube body 111 along its axial direction are respectively corresponding to a support end 101 and a mounting end 102. The tube body 111 is hollow to form the aforementioned mounting cavity 103. An opening 115 is formed on one side of the mounting end 102 of the mounting cavity 103. A stop wall 114 is provided on the outer side of the tube body 111. The tube cap 112 covers and closes the opening 115 and is abutted by the upper surface 1141 of the stop wall 114. The tube cap 112 and the tube body 111 are detachably connected by the nut 113 along the axial direction of the central axis 110. The nut 113 is sleeved on the outer wall of the tube body 111 and is threadedly connected to the tube cap 112. The side of the nut 113 facing away from the support end 101 is abutted by the lower surface 1142 of the stop wall 114. Wherein, the lamp head 300 is installed on the outer side of the tube cap 112. The power supply structure 420 includes a conductive wire 421. One end of the conductive wire 421 is electrically connected to the main board 410, and the other end extends out of the tube cap 112 through the opening 115 and is electrically connected to the lamp head.

[0049] It should be understood that, firstly, the central axis 110 is split into three parts: a detachable tube body 111, a tube cap 112 and a nut 113, which can facilitate the opening and closing of the mounting cavity 103 to facilitate the installation and accommodation of the power supply component in the mounting cavity 103. In other embodiments, if the convenient operation of opening and closing the mounting cavity 103 is not considered, the central axis 110 can also be integrally formed. That is, in this application, whether the central axis 110 is detachable is not limited. Secondly, the stop wall 114 is for positioning the snap connection of the tube cap 112 and the nut 113 (the tube cap 112 abuts the upper surface 1141 of the stop wall 114, and the nut 113 abuts the lower surface 1142 of the stop wall 114). In other embodiments, the positions where the tube cap 112 and the nut 113 abut the stop wall 114 can be replaced. Even without setting the stop wall 114, the tube cap 112 and the nut 113 can also achieve threaded connection. That is, in this application, whether the stop wall 114 is provided is not limited. In addition, the power supply structure 420 is a specific way to achieve electrical connection, including but not limited to the conductive wire 421, plug insertion, and conductive contact terminals. That is, the implementation method of the power supply structure 420 in this application is not limited, as long as it satisfies that the power supply structure 420 is electrically connected to the lamp head 300 and the main board 410 and rotates synchronously with the central axis 110.

[0050] Combined with reference to Figure 5 and Figure 8, the nut 113 protrudes from the outer wall of the mounting end 102. When the tripod 120 is in the retracted state (when the collar 121 slides to the farthest distance from the mounting end 102), the collar 121 abuts against the nut 113 along the axial direction of the central axis 110 to prevent the collar 121 from sliding off the central axis 110 on the side of the mounting end 102. It should be understood that in other embodiments where the nut 113 is not provided, a blocking portion 113a extending radially outward along the mounting end 102 needs to be provided on the outer side of the mounting end 102. At this time, when the collar 121 slides to the farthest distance from the mounting end 102, the collar 121 abuts against the blocking portion 113a, and the blocking portion 113a is used to prevent the collar 121 from sliding off the central axis 110; in addition, in other embodiments, without considering the collar 121 sliding off the central axis 110, the blocking portion 113a may not be provided. Therefore, in this application, the setting or not of the nut 113 and the blocking portion 113a is not limited.

[0051] Preferably, with reference to Figure 4 and Figure 7 , in this embodiment, the power supply assembly 400 further includes a battery 430. The battery 430 is electrically connected to the main board 410 and is accommodated in the first installation cavity 103. When the central axis 110 rotates circumferentially relative to the support plate 130, the battery 430 rotates synchronously with the central axis 110 relative to the tripod 120. It should be understood that in other embodiments, the power supply assembly 400 may not be provided with the battery 430. A power plug may be provided on the central axis 110. The power plug is electrically connected to the main board 410, and the power plug is inserted into an external power supply to supply power to the lamp head 300. In addition, here, the battery 430 may be a dry battery and needs to be replaced when the power is exhausted; the battery 430 may also be a storage battery and can be repeatedly used by charging with an external power supply. That is, in this application, the presence or absence of the battery 430 and the battery type are not limited.

[0052] Preferably, in this embodiment, with reference to Figure 9 and Figure 1G, the outrigger 122 rotates relative to the collar 121 about the first rotating shaft 124. The first rotating shaft 124 is perpendicular to both the axial direction and the radial direction of the central axis 110 and evenly surrounds the side circumference of the collar 121. A transfer block 1224 is connected to the first end 1221. A plurality of sets of spaced and opposite first lugs 1212 and second lugs 1213 protrude from the side circumference of the collar 121. The first rotating shaft 124 sequentially passes through the first lug 1212, the transfer block 1224, and the second lug 1213 along its axial direction to realize the rotational connection between the first end 1221 and the collar 121. An avoidance notch 1214 is formed between the first lug 1212 and the second lug 1213. When the first end 1221 and the collar 121 rotate relative to each other, the avoidance notch 1214 provides space for the transfer block 1224 to flip and move. It should be understood that the transfer block 1224 is rotationally connected to the first lug 1212 and the second lug 1213 through the first rotating shaft 124, realizing the rotational connection between the first end 1221 and the collar 121. In other embodiments, first, the transfer block 1224 can be connected to the collar 121, and the first lug 1212 and the second lug 1213 can protrude and be spaced at the end of the first end 1221. The first rotating shaft 124 can still sequentially pass through the first lug 1212, the transfer block 1224, and the second lug 1213 along its axial direction to realize the rotational connection between the first end 1221 and the collar 121. Second, in other embodiments, even if the first lug 1212, the transfer block 1224, and the second lug 1213 are not provided, by grooving and opening holes in the collar 121 or the first end 1221 such that the first rotating shaft 124 passes through the first end 1221 and the collar 121, the rotational connection between the first end 1221 and the collar 121 can also be realized, achieving the flipping and swinging of the outrigger 122 relative to the collar 121. That is, in the present application, the rotational connection manner between the first end 1221 and the collar 121 is not limited. Moreover, in the above rotational connection manner, the number of lugs and the number of transfer blocks 1224 are not limited, and the number is at least one and only needs to be passed through by the first rotating shaft 124.

[0053] Preferably, referring to Figure 3 , a support pad 125 is rotationally connected to the second end 1222 of the outrigger 122. The user can rotate and adjust the support pad 125 so that the tripod 120 receives a reaction force along the axial direction of the central axis 110 at any support angle, to meet the requirement that the lighting device 10 is balanced and supported on different support surfaces through the tripod 120. It should be understood that in other embodiments, if the support surface is a plane and the support force does not need to be adjusted for balance, the outrigger 122 may not be provided with the support pad 125. Therefore, in the present application, the number and shape of the support pads 125 are not limited.
