In order to adapt to more illumination use scenarios, the lamp head needs to flexibly change the circumferential illumination direction and the illumination height. For example, the patent CN117346115A discloses an illumination device, which needs to rotate the lamp head itself to change the circumferential illumination direction under the premise that the battery box and the support are relatively fixed; and under the premise that the lamp head and the battery box are relatively fixed, the support slides relative to the battery box to change the up-down height. That is, the up-down height and the circumferential direction of the lamp head need to be independently operated, and the operation of adjusting the height and the circumferential direction of the lamp head is tedious and time-consuming. SUMMARY

[0006] The present application provides an illumination device to facilitate user operation, conveniently and quickly adjust the up-down height and the circumferential direction of the lamp head, and adapt to more illumination scenarios.

[0007] To solve the above technical problems, the present application adopts the following technical solutions:

[0008] An illumination device, comprising:

[0009] In one of the embodiments, a middle shaft has an installation end and a support end opposite along the axial direction thereof;

[0010] A lamp head is connected to the installation end;

[0011] A support plate is rotationally connected to the support end along the circumferential direction of the middle shaft;

[0012] A foot support includes a sleeve ring, a plurality of legs, and a plurality of struts. The sleeve ring is sleeved on the outer sidewall of the middle shaft. The legs have first ends and second ends opposite along the axial direction thereof. The first ends are rotationally connected to the side periphery of the sleeve ring, and the second ends are supported on the support surface away from each other. The struts are connected between the support plate and the legs. The struts have third ends and fourth ends opposite along the axial direction thereof. The third ends are hingedly connected to the inner side of the legs, and the fourth ends are hingedly connected to the side periphery of the support plate.

[0013] The lantern ring can reciprocate along the axial direction of the central shaft to change the included angle between any two of the supporting leg, the supporting rod and the central shaft, so as to change the height of the foot stand; and the central shaft and the lamp head can synchronously rotate relative to the foot stand along the circumferential direction of the central shaft.

[0014] From the above technical solution, the embodiments of the present application have at least the following advantages and positive effects:

[0015] The lighting device provided by the present application has the following advantages. The lamp head is installed at one end of the central shaft as the lighting main body, and the foot stand is sleeved on the central shaft to form a support frame to support the lighting device on a support surface. Under the premise that the lamp head and the central shaft are relatively fixed, the foot stand can not only slide up and down relative to the central shaft to change the lighting height of the lamp head, but also can rotate relative to the central shaft to change the circumferential lighting direction of the lamp head. Therefore, compared with the traditional lighting device, for the lighting device of the present application, the user only needs to operate the sliding and rotation of the foot stand relative to the central shaft to correspondingly adjust the circumferential lighting direction and the lighting height of the lamp head.

FIG. 2 shows that the lighting device 10 is in the unfolded state, the lighting device 10 in the unfolded state has a higher lighting height and a larger lighting range, at this time, the user can hold it by hand, which provides lighting for a large range of moving space when camping outdoors, and is used as a moving street lamp or a detection lamp when walking at night, which not only facilitates the user to guide the light, but also facilitates the user to observe the surrounding environment. FIG. 3 shows that in other use scenarios, the user can further unfold the lighting device 10 into the support state to place the lighting device 10 on a flat or uneven support surface to provide the lighting function. For example, when reading a book or watching a computer at night, appropriate light is needed to protect the eyes from strong light, at this time, the lighting device 10 can be supported on the desktop as a desk lamp. It should be understood that the lighting device 10 of the present application does not necessarily have to present the storage state shown in FIG. 1 and the unfolded state shown in FIG. 2, only the lighting device 10 can present the support state shown in FIG. 3 to support the lighting device 10 on the support surface to provide the lighting function, and the angle of the support can be changed, and the support height of the lighting device 10 also changes.

The movable rod 200 moves relative to the support rod 100, so that the entire lighting device 10 can be switched between an unfolded state and a folded state. Preferably, the movable rod 200 of the present embodiment is rotatably connected to the outside of the support rod 100, and the movable rod 200 tilts and swings along the axial direction of the support rod 100 relative to the support rod 100, until the movable rod 200 is close to the support rod 100 side by side to realize the folding of the entire lighting device 10. It should be understood that in other embodiments, the lamp head 300 can be directly connected to the support rod 100 to form the lighting device 10, and in the present application, whether the movable rod 200 exists or not is not limited. Secondly, in other embodiments, the angle of the movable rod 200 tilting and swinging relative to the support rod 100 is not limited, that is, finally the movable rod 200 does not necessarily swing to be close to the support rod 100 side by side to realize the folding state of the lighting device 10. Finally, in other embodiments, the movable rod 200 does not necessarily tilt and swing relative to the support rod 100. That is, in the present application, whether the lighting device 10 is folded or not is not limited.

[0036] Specifically, in the present embodiment, the support rod 100 serves as a support body and has a support end 101 and a mounting end 102 opposite along the axial direction thereof, when the lighting device 10 is in the unfolded state, the support rod 100 can support the lighting device 10 on a support surface; the movable rod 200 has a first connecting end 201 and a second connecting end 202 opposite along the axial direction thereof, the first connecting end 201 is connected to the mounting end 102; and the second connecting end 202 is connected to the lamp head 300. Preferably, in the present embodiment, 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 can be flipped to be close to the support rod 100 side by side, 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 storage state. As shown in FIG. 1, when the lighting device 10 is in the storage state, that is, the movable rod 200 is in the posture of close to the support rod 100 side by side, the lamp head 300 is buckled on the support end 101. Here, buckling means close combination, which can be achieved by buckling, hooking, pasting, magnetic attraction and the like; the lamp head buckled on the support end 101 includes but is not limited to that the lamp head 300 can be buckled on the side circumference, edge or bottom of the support end 101. It should be understood that in other embodiments, whether the lamp head 300 is buckled on the support end 101 is not limited.

[0037] In the embodiment, in combination with reference to FIG. 3 and FIG. 4, the support rod 100 as a support body comprises a middle shaft 110 and a foot support 120, the middle shaft 110 has opposite ends along its axial direction corresponding to the support end 101 and the mounting end 102 described above respectively, the lamp holder 300 is connected to the mounting end 102 through the movable rod 200, the lamp holder 300 is mounted and connected to the outside of the mounting end 102 of the middle shaft 110 and can be circumferentially limited (here, the circumferential limitation refers to that the lamp holder 300 cannot rotate relative to the mounting end 102 around the circumferential direction of the middle shaft 110). The foot support 120 is connected to the outside of the middle shaft 110 and is in an unfolded support state to support the lighting device on a support surface. In the present application, the unfolded foot support 120 can rotate relative to the middle shaft 110 around the circumferential direction, and the lamp holder 300 rotates relative to the foot support 120 synchronously with the middle shaft 110 to change the circumferential illumination orientation of the lamp holder 300; the foot support 120 can slide relative to the middle shaft 110 along the axial direction of the middle shaft 110, the unfolding angle of the foot support 120 changes, and the support height of the foot support 120 changes accordingly to change the illumination height of the lamp holder 300.

[0038] Specifically, in combination with reference to FIG. 3 and FIG. 4, the support rod 100 further comprises a support plate 130, the support plate 130 is rotationally connected to the support end 101 along the circumferential direction of the middle shaft 110. The foot support 120 comprises a sleeve ring 121, a plurality of supporting legs 122, and a plurality of supporting rods 123, the number of the supporting legs 122 and the supporting rods 123 is the same and one-to-one corresponding, the sleeve ring 121 is sleeved on the outside of the middle shaft 110 and can rotate along the circumferential direction of the middle shaft 110, the sleeve ring 121 is slidingly connected to the middle shaft 110 along the axial direction of the middle shaft 110; the supporting leg 122 has a first end 1221 and a second end 1222 opposite along its axial direction, the first end 1221 is rotationally connected to the side circumference of the sleeve ring 121, and the second end 1222 is supported on the support surface away from each other; the supporting rod 123 is connected between the support plate 130 and the supporting leg 122, the supporting rod 123 has a third end 1231 and a fourth end 1232 opposite along its axial direction, the third end 1231 is hingedly connected (rotationally connected) to the inside of the supporting leg 122, and the fourth end 1232 is hingedly connected (rotationally connected) to the side circumference of the support plate 130.

[0039] The above structure can realize the circumferential rotation and axial sliding of the foot support 120 relative to the central shaft 110, and the realization process is as follows: the sleeve ring 121 and the support plate 130 rotate synchronously relative to the central shaft 110, driving the supporting leg 122 and the supporting rod 123 to rotate synchronously relative to the central shaft 110, so as to realize the circumferential rotation of the foot support 120 relative to the central shaft 110; preferably, in the embodiment, referring to FIGS. 2-3, the foot support 120 can be switched from the folded state (FIG. 2) to the unfolded state (FIG. 3), and the sleeve ring 121 slides along the central shaft 110 in the axial direction between the support end 101 and the mounting end 102. Specifically, when the sleeve ring 121 slides away from the mounting end 102, the first end 1221 is flipped outward relative to the sleeve ring 121, while driving the plurality of second ends 1222 to switch from the folded state of being close to each other to the supporting state of being away from each other, and synchronously, the supporting leg 122 drives the corresponding connected third end 1231 to switch from the folded state of being close to each other to the supporting state of being away from each other, and the fourth end 1232 is flipped outward relative to the support plate 130. In this way, the plurality of supporting legs 122 and the plurality of supporting rods 123 are switched from the folded state (FIG. 2) to the supporting state (FIG. 3), so that the foot support 120 is switched from the folded state to the unfolded state.

[0040] Preferably, in the embodiment, referring to FIG. 3, the sleeve ring 121 has a sleeve 1211 extending along the central shaft 110, and the sleeve 1211 is sleeved on the outer side wall of the central shaft 110, so as to more stably sleeve the foot support 120 on the outer side of the central shaft 110. In combination with FIGS. 5 and 6, when the foot support 120 is in the folded state, the sleeve 1211 is sleeved on the mounting end 102, the supporting rods 123 are side by side received in the support end 101, and the sleeve ring 121 and the supporting rods 123 are spaced apart from the outer side wall of the central shaft 110 in the axial direction of the central shaft 110. Preferably, in the embodiment, the inner side of the supporting leg 122 is provided with a receiving groove 1223, and when the foot support 120 is in the folded state, the receiving groove 1223 receives the sleeve ring 121 and the supporting rods 123. This design makes the central shaft 110 and the foot support 120 more compact in the folded state.

[0041] It should be understood that, first, in other embodiments, without considering the stability of the sleeve of the foot support 120 on the central shaft 110, the sleeve ring 121 can not be provided with the extending sleeve 1211 part, and the foot support 120 can be simply sleeved on the outer side of the central shaft 110; second, in other embodiments, when the foot support 120 is in the folded state, without considering the compactness of the receiving structure of the supporting rod 100, the inner side of the supporting leg 122 can not be provided with the receiving groove 1223. Therefore, in the present application, whether the sleeve 1211 and the receiving groove 1223 are provided or not is not limited.

[0042] Here, for the convenience of understanding, with reference to FIG. 3, the planar triangle abc formed by the leg 122, the corresponding connecting strut 123, and the central axis 110 is defined. During the reciprocating movement (sliding) of the sleeve ring 121 along the axial direction of the central axis 110, the three internal angles of the triangle abc change, and the three internal angles of the triangle abc correspond to the included angle between any two of the leg 122, the corresponding connecting strut 123, and the central axis 110. Here, the length extension direction of the central axis 110 does not change (parallel to the height direction supported by the foot stool 120), and the support height of the foot stool 120 changes, that is, the rotatingly connected leg 122 and strut 123 can change the unfolding angle and support height of the foot stool 120. When the foot stool 120 is in the folded state (as shown in FIG. 2), the three internal angles of the triangle abc are all 0 degrees, at this time, the plurality of legs 122 and the plurality of struts 123 are all in a side-by-side folding posture with the central axis. It should be understood that in other embodiments, the sleeve ring 121 cannot reduce the three internal angles of the triangle abc to 0 degrees during the sliding process, that is, the foot stool 120 cannot be completely folded. That is, in the present application, whether the foot stool 120 is folded or not is not limited, as long as the support height can be changed.

[0043] The present application provides a lighting device, comprising a lamp holder 300, a central axis 110 and a foot stool 120. The lamp holder 300 serves as the lighting main body and is connected and mounted to one end (mounting end 102) of the central axis 110. The foot stool 120 is sleeved on the central axis 110 to form a support frame, so as to support the lighting device 10 on a support surface. Under the premise that the lamp holder 300 and the central axis 110 are relatively fixed, the foot stool 120 not only can slide up and down relative to the central axis 110 to change the lighting height of the lamp holder 300, but also can rotate circumferentially relative to the central axis 110 to change the circumferential lighting direction of the lamp holder 300. Therefore, compared with the lighting device 10 disclosed in the patent CN117346115A, for the lighting device 10 of the present application, the user only needs to operate the sliding and rotation of the foot stool 120 relative to the central axis 110 to correspondingly adjust the circumferential lighting direction and the lighting height of the lamp holder 300. That is, the user can hold the central axis with one hand and turn the foot stool 120 with the other hand to realize the adjustment of the lighting height and the circumferential lighting direction, which conforms to the ergonomic design, greatly improves the convenience and practicality of the lighting device 10 itself, and improves the user experience.

[0044] Preferably, in the present application, in combination with reference to FIG. 4 and FIG. 7, the lighting device 10 further comprises a power supply assembly 400, the middle shaft is provided with a mounting cavity 103, the power supply assembly 400 is arranged in the mounting cavity 103, the power supply assembly 400 comprises a main plate 410 and a power supply structure 420 arranged on the main plate 410, and the main plate 410 is electrically connected to the lamp holder 300 through the power supply structure 420. The main plate 410 and the power supply structure 420 of the present application can rotate synchronously with the middle shaft 110 relative to the foot support 120 in the circumferential direction, so that the lamp holder 300, the main plate 410 and the power supply structure 420 can rotate synchronously with the middle shaft 110 relative to the foot support 120. In this way, the electrical contact stability of the entire lighting device 10 is enhanced, and the lighting life of the lighting device 10 is prolonged. It should be understood that in other embodiments of the present application, whether the lamp holder 300, the main plate 410 and the power supply structure 420 rotate synchronously is not limited without considering the electrical contact stability.

[0045] Preferably, in the present embodiment, in combination with reference to FIG. 4 and FIG. 8, the middle shaft 110 comprises a tube body 111, a tube cover 112 and a nut 113, the tube body 111 has opposite two ends corresponding to the support end 101 and the mounting end 102 along the axial direction thereof, the tube body 111 is hollow to form the mounting cavity 103 described above, the mounting cavity 103 is formed with an opening 115 on the side of the mounting end 102, the outer side of the tube body 111 is provided with a blocking wall 114, and the tube cover 112 covers and closes the opening 115 and is abutted by the upper side surface 1141 of the blocking wall 114. The tube cover 112 is detachably connected to the tube body 111 in the axial direction of the middle shaft 110, the nut 113 is sleeved on the outer side wall of the tube body 111 and is threadedly connected to the tube cover 112, and the side of the nut 113 away from the support end 101 is abutted by the lower side surface 1142 of the blocking wall 114. The lamp holder 300 is mounted on the outer side of the tube cover 112, and the power supply structure 420 comprises a conductive wire 421, one end of the conductive wire 421 is electrically connected to the main plate 410, and the other end of the conductive wire 421 extends out of the tube cover 112 through the opening 115 and is electrically connected to the lamp holder.

[0046] It needs to be understood that, first, the middle shaft 110 is split into three parts of the tube body 111, the tube cover 112 and the nut 113 which are detachably connected, which can facilitate the opening and closing of the installation cavity 103, so as to facilitate the installation of the power supply assembly in the installation cavity 103. In other embodiments, without considering the convenient operation of opening and closing the installation cavity 103, the middle shaft 110 can also be integrally formed. That is, in the present application, whether the middle shaft 110 is detachable is not limited. Second, the blocking wall 114 is used to position the clamping connection of the tube cover 112 and the nut 113 (the tube cover 112 abuts against the upper side surface 1141 of the blocking wall 114, and the nut 113 abuts against the lower side surface 1142 of the blocking wall 114). In other embodiments, the positions of the tube cover 112 and the nut 113 abutting against the blocking wall 114 can be replaced, or even the blocking wall 114 is not provided, and the tube cover 112 and the nut 113 can also be threadedly connected. That is, in the present application, whether the blocking wall 114 is provided or not is not limited. In addition, the power supply structure 420 is a specific way to realize electrical connection, including but not limited to conductive wire 421, plug insertion, conductive contact terminal. That is, the way of realizing the power supply structure 420 in the present application is not limited, as long as the power supply structure 420 is electrically connected to the lamp holder 300 and the main board 410 and rotates synchronously with the middle shaft 110.

[0047] With reference to FIGS. 5 and 8, the nut 113 protrudes from the outer side wall of the installation end 102, and when the foot support 120 is in the storage state (when the sleeve ring 121 slides to the farthest distance from the installation end 102), the sleeve ring 121 abuts against the nut 113 along the axial direction of the middle shaft 110, so as to prevent the sleeve ring 121 from sliding away from the middle shaft 110 on the side of the installation end 102. It needs to be understood that, in other embodiments, without the nut 113, the outer side of the installation end 102 needs to be provided with a blocking portion 113a extending radially outward, at this time, when the sleeve ring 121 slides to the farthest distance from the installation end 102, the sleeve ring 121 abuts against the blocking portion 113a, and the blocking portion 113a is used to prevent the sleeve ring 121 from sliding away from the middle shaft 110; in addition, in other embodiments, without considering the sliding of the sleeve ring 121 away from the middle shaft 110, the blocking portion 113a can also not be provided.
