[0045] The present application provides a lighting device 1, which is specifically a standing lamp. When a user needs to work outdoors, the user can carry the lighting device 1 to any location outdoors to provide lighting needs. The lighting device 1 is different from a household table lamp, which usually needs to be placed on a desktop for lighting and does not need to be carried or moved. However, the lighting device 1 provided in the present application is a work standing lamp, which can stand on the ground or other work surfaces and illuminate any work area with lighting needs.

[0046] like Figures 1 to 6 As shown, the lighting device 1 includes a lamp head assembly 100, a support rod assembly 200 and a support base assembly 300. The lamp head assembly 100 includes at least one lighting lamp 101, which can change the visual environment of the user after being turned on, so that the user can work better. The support rod assembly 200 is connected to the lamp head assembly 100, and the support rod assembly 200 is used to support the lamp head assembly 100. The support base assembly 300 is connected to the support rod assembly 200 and is used to support the support rod assembly 200. The support base assembly 300 is arranged at the end of the support rod assembly 200, and optionally, the support base assembly 300 is arranged at the bottom end of the support rod assembly 200. The support base assembly 300 includes a base portion 310 connected to the support rod assembly 200 and a leg portion 320 connected to the base portion 310. In some embodiments, the support rod assembly 200 may not be provided, and the lamp head assembly 100 is connected to the support base assembly 300. That is to say, the support base assembly 300 can support the lighting device 1 to be stably placed, and at the same time, the other surface of the support base assembly 300 supports the lamp holder assembly 100 .

[0047] The first end of the leg portion 320 is connected to the base portion 310, and the second end of the leg portion 320 is configured to have: a first position in which the leg portion 320 is unfolded relative to the base portion 310 and extends beyond the coverage range of the base portion 310, and a second position in which the leg portion 320 is at least partially folded into the base portion 310 relative to the base portion 310. In the first position and the second position, the axial distance between the first end of the leg portion 320 and the base portion 310 is substantially unchanged, and the position of the geometric center of the support base assembly 300 is substantially unchanged. When the leg portion 320 of the lighting device 1 is in the first position, that is, when the leg portion 320 is unfolded, the area of ​​the support base assembly 300 becomes larger to ensure stable support. On the other hand, when the leg portion 320 is changed from the first position to the second position and after the change, that is, whether the area of ​​the support base assembly 300 changes or not, its geometric center does not change, so there is no need to adjust the position of the lamp head assembly 100 or the support rod assembly 200 when the area of ​​the support base assembly 300 changes. Whether the position of the leg portion 320 changes or not does not affect the use of the lamp head assembly 100.

[0048] In this embodiment, when the second end of the leg portion 320 is in the first position or in the second position, the support base assembly 300 can stably support the lighting device 1, so the lighting device 1 can be used and operated regardless of whether the leg portion 230 is unfolded. Compared with the related art, in which the standing lighting device 1 with a tripod support frame must be unfolded when in use, the lighting device provided by the present application can also be used in a small space, and the lighting device occupies less space. The lighting device 1 is not only compact in structure and small in size, but also can stand without relying on the unfolded leg portion 320, making the lighting device 1 convenient to store, transport and carry.

[0049] like Figure 1-2 As shown, when the second end of the leg portion 320 is in the second position, it is defined that the support base assembly 300 is in the first working state. When the support base assembly 300 is in the first working state, the leg portion 320 is completely retracted within the coverage of the base portion 310. The structure of the lighting device 1 for supporting its stable placement is arranged within the coverage of the base portion 310. In this embodiment, the second end of the leg portion 320 is provided with a supporting foot 322, and the supporting foot 322 is formed or connected with the second end of the leg portion 320. The top end of the supporting foot 322 is connected to the bottom surface of the leg portion 320, and the bottom end of the supporting foot 322 extends out of the base portion 310, and the supporting foot 322 is supported on the plane (i.e., the ground or work surface) where the lighting device 1 is placed. In some embodiments, the height of the supporting foot 322 is set to be flush with the bottom surface of the base portion 310, and the base portion 310 also supports the lighting device 1 to work in the first working state. In this way, the lighting device 1 can stand on the ground without relying on other devices. This helps to free the user, so that the user can go to work after carrying the lighting device 1 to the working environment.

[0050] In this embodiment, if Figure 3 As shown, when the second end of the leg portion 320 is in the first position, it is defined that the support base assembly 300 is in the second working state. When the support base assembly 300 is in the second working state, the second end of the leg portion 320 is unfolded relative to the base portion 310 and extends out of the coverage of the base portion 310 to support the lighting device 1 to work. At this time, the base portion 310 and the leg portion 320 work together to greatly improve the standing stability of the lighting device 1, reduce the probability of the lighting device 1 tipping over, and reduce the probability of the lighting device 1 being damaged due to tipping over.

[0051] Continue to refer to Figure 2 and Figure 3 As shown, the lamp head assembly 100 is arranged at the top end of the support rod assembly 200, and the number of the lighting lamps 101 can be set to one or more according to needs.

[0052] When the illuminating lamp 101 is configured as a plurality, the plurality of illuminating lamps 101 are evenly distributed around the circumference of the support rod assembly 200. In one embodiment, the number of illuminating lamps 101 is configured as three. The three illuminating lamps 101 are evenly distributed around the circumference of the support rod assembly 200. Of course, in other embodiments, the number of illuminating lamps 101 can also be set to other numbers according to needs, such as 2, 4 or more.

[0053] In some alternative embodiments, the lighting lamp 101 can be installed on the support rod assembly 200 by a detachable connection, so that the user can adjust the lamp head assembly 100 to a single lamp head or multiple lamp heads according to needs. The detachable connection method includes but is not limited to magnetic attraction, connector connection, snap connection, etc.

[0054] In some embodiments, the structures of the multiple lighting lamps 101 are the same, such as Figure 2 As shown, the illuminating lamp 101 has surface light sources of equal size, and the surface light sources can be circular light sources, square light sources, etc. Of course, in some other embodiments, the structures of the multiple illuminating lamps 101 can also be different, for example, including a main lamp and an auxiliary lamp, the auxiliary lamp is arranged on the side of the main lamp, and the auxiliary lamp can be turned on or off according to the needs of the user, and the main lamp and the auxiliary lamp can be unfolded into a plane, thereby increasing the light source area.

[0055] To facilitate installation of the lighting lamp 101, continue to refer to Figure 2 and Figure 3 As shown, the lamp holder assembly 100 further includes a lamp holder 102, which is sleeved and fixed on the support rod assembly 200, and the illuminating lamp 101 is connected to the lamp holder 102. In this embodiment, for a plurality of illuminating lamps 101 evenly arranged around the circumference, the lamp holder 102 is a ring structure. In order to facilitate the storage of the lamp holder assembly 100, one end of the illuminating lamp 101 is rotatably connected to the lamp holder 102, so that the illuminating lamp 101 can be recovered to Figure 1 The folded state shown can also be unfolded to Figure 2 Of course, the illuminating lamp 101 can also be rotated to a horizontal state, that is, the lamp body of the illuminating lamp 101 directly illuminates the ground. For the lamp head assembly 100 of a single lamp, the illuminating lamp 101 can also be rotated and connected to the lamp holder 102. The maximum rotation angle of the illuminating lamp 101 can reach 360° to meet the lighting requirements at various angles.

[0056] The rotatable connection of the lighting lamp 101 to the lamp holder 102 not only improves the storage of the lamp head assembly 100, but also enables the light angle to be adjusted by rotating the lighting lamp 101, making the use of the lighting lamp 101 more flexible and better able to meet the needs of users. The specific manner in which the lighting lamp 101 can be rotatably connected is: a rotation axis is provided at one end of the lighting lamp 101, a rotation axis hole is provided on the lamp holder 102, and the rotation axis is rotatably connected in the rotation axis hole. In some embodiments, three pairs of rotation axis holes are provided in the circumference of the lamp holder 102, and the rotation axes of the three lighting lamps 101 are connected in the three pairs of rotation axis holes one by one. The rotations of the three lighting lamps 101 are independent of each other, and different lighting lamps 101 can be adjusted to different lighting angles according to needs.

[0057] The support rod assembly 200 includes a rod member of a tubular structure, and the rod member can be a round tube, a square tube, a special-shaped tube, etc. In some embodiments, the rod member is a non-retractable straight rod structure. In this embodiment, the rod member is a retractable telescopic rod, and optionally, Figure 2 As shown, the rod member includes a central tube 201 and at least one extension tube 202, the bottom end of the central tube 201 is fixedly connected to the support seat assembly 300, wherein the extension tube 202 connected to the central tube 201 is sleeved inside or outside the central tube 201 and can slide relative to the axial direction of the central tube 201, so that the extension length of the rod member changes, and the other extension tubes 202 are slidably sleeved in turn, and the rod member can be moved by pulling the extension tube 202. Figure 1 The folded state shown switches to Figure 2 The extended state shown in FIG. 1 or the rod is moved by pushing the extension tube 202 so that the rod Figure 2 The extended state shown switches to Figure 1 The folded state shown in the figure makes the support rod assembly 200 easy to store, carry and transfer. Figure 1 In the folded state shown, the illuminating lamp 101 can still rotate, and the working state of the support base assembly 300 can also be switched, and the operation of the illuminating lamp 101 is not affected. By providing the lamp head assembly 100, the support rod assembly 200 and the support base assembly 300 that work independently of each other, the illuminating device 1 includes multiple working postures, which can cover more use environments and use conditions.

[0058] The support base assembly 300 is used to support the above-mentioned support rod assembly 200. The base portion 310 of the support base assembly 300 is the main supporting structure. In some embodiments, the base portion 310 is disc-shaped. Of course, in other embodiments, the shape of the base portion 310 can also be set to square, oval, etc. according to requirements. The central tube 201 of the support rod assembly 200 can be directly fixed on the top surface of the base portion 310, or a connecting structure can be set at the bottom end of the central tube 201 to fix the connecting structure on the top surface of the base portion 310.

[0059] The number of the leg parts 320 can be set to one or more according to the needs. In some embodiments, the number of the leg parts 320 is multiple, and when the second end of the leg part 320 is in the first position, the multiple leg parts 320 are radially extended with the geometric center of the base part 310 as the center. Such a setting makes the multiple leg parts 320 retractable and retractable, with high retractable efficiency, small footprint after retraction, and high support stability after extension.

[0060] In some embodiments, the plurality of leg portions 320 are configured with different lengths or shapes and sizes, so that after the plurality of leg portions 320 are radially deployed, the position of the geometric center of the support base assembly 300 remains substantially unchanged.

[0061] In this embodiment, if Figures 3 to 6 As shown, the first end of each leg portion 320 is rotatably connected to the base portion 310 via a rotating shaft 323 , and the plurality of leg portions 320 are radially rotated and spread out with the center of the base portion 310 as the center.

[0062] In order to realize the synchronous rotation and deployment of the plurality of leg portions 320, in some embodiments, the base portion 310 further includes a turntable 311 and a base 312, the base 312 is connected to the bottom end of the support rod assembly 200, and the turntable 311 rotates around the first axis a to drive the rotation and deployment of the leg portions 320. The bottom plate of the support rod assembly 200 can be integrally formed with the base 312, or the bottom plate can be directly fixed on the top surface of the base 312.

[0063] Optional, such as Figure 4 As shown, the base 312 includes a first chassis 3121 and a second chassis 3122 spaced apart from each other, the bottom end of the central tube 201 is connected to the first chassis 3121, and the second chassis 3122 is close to the ground. There is a gap between the first chassis 3121 and the second chassis 3122, and a receiving space for receiving a plurality of leg portions 320 is formed between the first chassis 3121 and the second chassis 3122. In order to achieve relative fixation of the first chassis 3121 and the second chassis 3122, a support ring plate is further provided between the first chassis 3121 and the second chassis 3122, the top of the support ring plate abuts against the bottom surface of the first chassis 3121, and the bottom of the support ring plate abuts against the top surface of the second chassis 3122, and screws pass through the second chassis 3122, the threaded holes formed on the support ring plate, and the first chassis 3121, thereby achieving connection and fixation of the first chassis 3121 and the second chassis 3122. Of course, in addition to the screw connection, other methods can also be used to achieve the connection between the first chassis 3121 and the second chassis 3122. As for the support ring plate, it can also be integrally formed with the first chassis 3121 or the second chassis 3122.

[0064] Of course, in other embodiments, the base 312 may also be configured as other forms according to needs, such as including only a second chassis 3122 .

[0065] In order to achieve high-precision deployment and storage of the leg part 320, in some embodiments, a guide hole 3124 is provided on the base 312. Optionally, the guide hole 3124 is provided on the first chassis 3121, and the guide hole 3124 is concentrically provided with the first chassis 3121. The number of the guide holes 3124 is the same as the number of the leg part 320, and the plurality of guide holes 3124 are arranged at intervals in the circumferential direction around the first axis a. A driving slot 321 is provided on the leg part 320, and a toggle pin 313 is provided on the turntable 311. The toggle pin 313 passes through the guide hole 3124 and is slidably connected in the driving slot 321. The turntable 311 is rotated around the first axis a, so that the toggle pin 313 moves synchronously in the guide hole 3124 and the driving slot 321 while rotating around the first axis a, so that the leg part 320 moves between the first position and the second position through rotation.

[0066] The rotating disk 311 is a driving member, and the rotating disk 311 includes an annular portion 3111 and an extension portion 3112. The annular portion 3111 is rotatably sleeved on the bottom end of the central tube 201, and the extension portion 3112 extends radially outward from the annular portion 3111. The toggle pin 313 is convexly arranged at one end of the extension portion 3112 away from the annular portion 3111. The user applies a rotational torque to the annular portion 3111, so that the annular portion 3111 rotates around the central tube 201, and the toggle pin 313 can be driven by the extension portion 3112 to move in the guide hole 3124 and the driving groove 321.

[0067] like Figure 5 As shown, the support seat assembly 300 includes three leg portions 320, and correspondingly, the rotating disk 311 includes an annular portion 3111 and three extension portions 3112, the three extension portions 3112 are arranged at intervals around the circumference of the annular portion 3111, each extension portion 3112 extends along the radial direction of the annular portion 3111, one end of the extension portion 3112 is connected to the outer annular surface of the annular portion 3111, and the driving pin 313 is convexly arranged at the other end of the extension portion 3112. Three guide holes 3124 are arranged on the first chassis 3121, the first end of the leg portion 320 is rotatably connected to the second chassis 3122, each leg is provided with a driving slot 321, and the three driving pins 313 pass through the three guide holes 3124 one by one, and are slidably connected to the three driving slots 321 one by one.

[0068] In some embodiments, a plurality of driving slots 321 are arranged at intervals on the leg portion 320, and the toggle pin 313 can be selectively slidably connected in one of the driving slots 321. In one embodiment, at least some of the driving slots 321 have different curvatures; in another embodiment, at least some of the driving slots 321 have different lengths. In this way, the leg portion 320 has different support ranges and is more versatile.

[0069] Continue to refer to Figure 5 As shown, three driving slots 321 are formed on each leg portion 320 , so that the driving pin 313 can be placed in any driving slot 321 , thereby changing the deployment trajectory and the recovery trajectory of the leg portion 320 .

[0070] Continue to refer to Figure 5 As shown, in order to improve the stability of the supporting leg portion 320 supporting the ground, a supporting foot 322 is provided at the second end of each supporting leg portion 320. In one embodiment, the supporting foot 322 is cylindrical.

[0071] In order to improve the compactness of the structure of the entire support base assembly 300, in some embodiments, a receiving groove 3123 for receiving the support foot 322 provided at the second end of the leg portion 320 is provided at the edge of the second chassis 3122. In a specific embodiment, the opening direction of the receiving groove 3123 forms an angle with the radial direction of the second chassis 3122, and the extension direction of the receiving groove 3123 matches the moving track of the support foot 322, so that the support foot 322 can smoothly enter and exit the receiving groove 3123. Optionally, three receiving grooves 3123 are provided at equal intervals at the edge of the second chassis 3122, and the support feet 322 provided at the three leg portions 320 can be inserted into the three receiving grooves 3123 one by one.

[0072] In some embodiments, Figure 6 As shown, when the support base assembly 300 is in the first working state, the leg portion 320 includes a storage state that is basically hidden in the space formed between the first chassis 3121 and the second chassis 3122. Such a configuration improves the compactness of the entire support base assembly 300, making the lighting device 1 easier to store and transport.

[0073] like Figure 5 As shown, when the support base assembly 300 is in the second working state, the second end of the leg portion 320 is in a non-retracted state.

[0074] In some alternative embodiments, in addition to radially rotating and unfolding, the leg portion 320 can also radially move linearly. The first ends of the leg portions 320 are respectively slidably connected to the base portion 310, and the multiple leg portions 320 can be radially and linearly unfolded with the center of the base portion 310 as the center. That is, a slideway is formed on the surface or inside of the base portion 310, and the leg portion 320 includes a long strip-shaped slide bar, which is slidably connected in the corresponding slideway. By pulling the leg portion 320, the leg portion 320 is extended to the outside of the base portion 310, so that the multiple leg portions 320 are radially and horizontally unfolded with the center of the base portion 310 as the center.

[0075] The base portion 310 is disc-shaped, and the leg portion 320 also includes an arc block connected to the slide bar. The arc surface of the arc block is matched with the arc surface of the base portion 310, so that when the leg portion 320 is in the storage state stored in the base portion 310, the arc surface of the arc block can be flush with the arc surface of the base portion 310, and the arc surfaces of multiple leg portions 320 can be spliced ​​to form a complete annular surface. Support feet are also provided on the bottom surface of the arc block, and an avoidance groove for avoiding the support feet is provided on the base portion 310. When the leg portion 320 is folded into the base portion 310, the support foot is placed in the avoidance groove. When the leg portion 320 is unfolded and extends the base portion 310, the support foot is supported on the ground.

[0076] In some alternative embodiments, the supporting feet may be replaced by universal wheels with a locking function, so that the lighting device 1 is easy to move and can be fixed by locking the universal wheels after being moved into place.

[0077] It should be noted that an elastic member may be provided between the slide bar and the base portion 310, and a button may be provided on the base portion 310. By pressing the button, the slide bar may be automatically popped out, thereby enabling the leg portion 320 to have an automatic pop-up function. The implementation here is similar to the press-to-open operation of an umbrella, so it will not be described in detail here.

[0079] In some embodiments, the battery pack 400 is disposed on the support rod assembly 200 and is located above the support seat assembly 300 ; in some embodiments, the battery pack 400 is disposed on the support seat assembly 300 .

[0080] In order to stably fix the battery pack 400 on the support rod assembly 200, continue to refer to Figure 4 As shown, the lighting device 1 further includes a battery mounting member 500, which includes a mounting shell 501 and a first tube hoop 502 and a second tube hoop 503 connected to the mounting shell 501. The first tube hoop 502 and the second tube hoop 503 are arranged at intervals and can be simultaneously sleeved on the central tube 201. A plug-in cavity is formed on the mounting shell 501, and the battery pack 400 can be inserted and removed from the mounting shell 501 by plugging, and a conductive member for connecting the battery pack 400 and the lighting is formed in the mounting shell 501. The mounting shell 501 has the function of protecting and holding the battery pack 400, and the two tube hoop cooperate with the central tube 201 so that the battery pack 400 can be stably fixed on the support rod assembly 200.

[0081] In order to facilitate the control of the on and off of the electrical connection between the illuminating lamp 101 and the battery pack 400, a button is further provided on the first chassis 3121, and the illuminating lamp 101 is turned on or off by touching the button. Optionally, a control circuit board for controlling the on and off of the illuminating lamp 101 is further provided between the first chassis 3121 and the second chassis 3122, and the control circuit board includes a PCB circuit board (Printed Circuit Board) and an FPC circuit board (Flexible Printed Circuit Board).

[0082] The lighting device 1 has a longest state, and the overall height of the lighting device 1 is greater than or equal to 1.5m and less than or equal to 3m. The lighting device 1 has a storage state. When the lighting device 1 is in Figure 1 In the storage state shown, the overall height of the lighting device 1 is 420 mm. The height of the lighting device 1 in the storage state is low enough to facilitate storage and transportation by the user. Figure 1 In the storage state shown, the overall height of the lighting device 1 may also be other data, which are not listed here one by one.

[0083] As another embodiment of the present application, Figures 4 to 5As shown, a support mechanism is used to support functional components. The support mechanism includes a support rod assembly 200 and a support seat assembly 300. Functional components include lamps, fan bodies, fans (garden-type blowing devices), photoelectric detection equipment, etc. The support rod assembly 200 is connected to the lamp head assembly 100, and the support rod assembly 200 is used for functional components (such as fans). The support seat assembly 300 is connected to the support rod assembly 200 and is used to support the support rod assembly 200. The support seat assembly 300 is arranged at the end of the support rod assembly 200, and optionally, the support seat assembly 300 is arranged at the bottom end of the support rod assembly 200. The support seat assembly 300 includes a base portion 310 connected to the support rod assembly 200 and a leg portion 320 connected to the base portion 310. Among them, the first end of the leg portion 320 is connected to the base portion 310, and the second end of the leg portion 320 is configured to have: a first position in which the leg portion 320 is unfolded relative to the base portion 310 and extends out of the coverage range of the base portion 310, and a second position in which the leg portion 320 is at least partially folded in the base portion 310 relative to the base portion 310. In the first position and the second position, the axial distance between the first end of the leg portion 320 and the base portion 310 is basically unchanged, and the position of the geometric center of the support seat assembly 300 is basically unchanged. When the leg portion 320 of the lighting device 1 is in the first position, that is, when the leg portion 320 is unfolded, the area of ​​the support seat assembly 300 becomes larger to make the support stable. On the other hand, when the leg portion 320 changes from the first position to the second position and after the change, that is to say, whether the area of ​​the support seat assembly 300 changes or not, its geometric center does not change, so there is no need to adjust the position of the functional component or the support rod assembly 200 when the area of ​​the support seat assembly 300 changes. Whether the position of the leg portion 320 changes or not does not affect the use of the functional component.
