[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] In this application, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0052] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0053] Please also read Figure 1 and Figure 2 The embodiment of the present application provides a lighting device 1, comprising a frame 11, a lighting mechanism 12, a driving mechanism 13 and a guiding mechanism 14. The lighting mechanism 12 is located above the frame 11. The driving mechanism 13 is disposed on the frame 11, and the driving mechanism 13 is connected to the lighting mechanism 12 to drive the lighting mechanism 12 to move in the vertical direction. The guiding mechanism 14 comprises a guide rod 141 and a guide member 142, the guide rod 141 is disposed on the frame 11 and extends in the vertical direction, the guide member 142 is sleeved on the guide rod 141 and can move along the guide rod 141, and the guide member 142 is connected to the driving mechanism 13.

[0054] The frame 11 may be a cylindrical column or other shapes, which are not limited here.

[0055] The driving mechanism 13 is connected to the lighting mechanism 12 and can drive the lighting mechanism 12 to move in a vertical direction, so that the height of the lighting can be adjusted to meet the needs of the application scene.

[0056] When the driving mechanism 13 drives the lighting mechanism 12 to move, the guide member 142 moves synchronously on the guide rod 141. The cooperation between the guide member 142 and the guide rod 141 can prevent the driving mechanism 13 from shaking or deviating, thereby avoiding the driving mechanism 13 from getting stuck and ensuring the reliability of the driving mechanism 13.

[0057] See also Figure 2 In some embodiments, the frame 11 is provided with a first accommodating cavity 111 and a second accommodating cavity 112 that are connected, the driving mechanism 13 is partially disposed in the first accommodating cavity 111 , and the guide rod 141 is disposed in the second accommodating cavity 112 .

[0058] The frame 11 is provided with a first accommodating chamber 111, and the driving mechanism 13 is partially arranged in the first accommodating chamber 111, which can protect the driving mechanism 13 and extend the service life of the driving mechanism 13. Similarly, the frame 11 is provided with a second accommodating chamber 112, and the guide rod 141 is arranged in the second accommodating chamber 112, which can protect the guide rod 141 and extend the service life of the guide rod 141.

[0059] In some other embodiments, the guide rod 141 and the driving mechanism 13 are disposed in the same accommodating cavity.

[0060] Please also read Figure 1 and Figure 2 In some embodiments, the driving mechanism 13 includes a screw 131 and a sleeve 132. The screw 131 is rotatably disposed on the frame 11, and the axial direction of the screw 131 is parallel to the vertical direction. The sleeve 132 is sleeved on the screw 131 and is threadedly engaged with the screw 131. The sleeve 132 is connected to the guide member 142, and the sleeve 132 is connected to the lighting mechanism 12.

[0061] The screw rod 131 and the sleeve 132 are threadedly matched, so that the height of the sleeve 132 can be precisely adjusted, thereby achieving precise adjustment of the height of the lighting mechanism 12 .

[0062] At the same time, the screw 131 and the sleeve 132 cooperate with each other through the thread, which can improve the bearing capacity of the sleeve 132. Since the thread can withstand greater force and torque, the stability of the lighting mechanism 12 during movement can be ensured, and the lighting mechanism 12 can be prevented from shaking during movement.

[0063] In addition, the screw 131 and the sleeve 132 are threadedly matched so that the sleeve 132 can be self-locked after the screw 131 stops rotating, so as to keep the relative positions of the screw 131 and the sleeve 132 unchanged and prevent the lighting mechanism 12 from shifting when it does not need to move.

[0064] In some other embodiments, the driving mechanism 13 may also use a cylinder instead of the screw 131 and the sleeve 132 .

[0065] Please also read Figure 1 , Figure 2 and Figure 3 In some specific embodiments, the driving mechanism 13 further includes a gear assembly 133 and a driving assembly 134. The gear assembly 133 is connected to the screw rod 131. The driving assembly 134 is connected to the gear assembly 133, and the driving assembly 134 drives the screw rod 131 to rotate through the gear assembly 133.

[0066] The driving assembly 134 drives the screw 131 to rotate through the gear assembly 133, preventing the screw 131 from being directly driven by the driving assembly 134 and avoiding the screw 131 from being directly subjected to force, so as to protect the screw 131 and extend the service life of the screw 131. At the same time, the gear transmission can ensure that the transmission between the screw 131 and the driving assembly 134 is more efficient and stable, which can not only reduce the energy loss during the transmission process, but also accurately adjust the height of the lighting mechanism 12. In addition, the gear transmission makes the transmission process smoother, reduces the damage caused by vibration and impact to the screw 131 and the lighting mechanism 12, and helps to improve the service life and stability of the lighting device 1.

[0067] In some other more specific implementations, the driving assembly 134 may also directly drive the screw rod 131 to rotate.

[0068] Please also read Figure 2 and Figure 3 In some more specific embodiments, the gear assembly 133 includes a first helical tooth 1331 and a second helical tooth 1332. The first helical tooth 1331 is sleeved on the screw rod 131. The second helical tooth 1332 is meshed with the first helical tooth 1331, and the second helical tooth 1332 is connected to the driving assembly 134.

[0069] In this embodiment, the first beveled teeth 1331 mesh with the second beveled teeth 1332 to change the transmission direction. Specifically, the first beveled teeth 1331 are sleeved on the screw rod 131 so that the axis of the first beveled teeth 1331 is coaxial with the axis of the screw rod 131, and the second beveled teeth 1332 mesh with the first beveled teeth 1331 so that the axis of the second beveled teeth 1332 can be parallel to the horizontal direction, which can avoid the lighting device 1 being too high and causing a high center of gravity, and prevent the lighting device 1 from easily tipping over.

[0070] In addition, the first helical teeth 1331 mesh with the second helical teeth 1332, and the helical teeth meshing area is larger than that of the straight teeth meshing, so the first helical teeth 1331 and the second helical teeth 1332 can withstand greater loads and torques than the supporting meshing, making the gear assembly 133 more efficient in transmitting power, reducing energy loss and improving transmission efficiency. At the same time, the helical teeth meshing makes the transmission process have less impact and vibration, ensuring the stability in the process of adjusting the height of the lighting mechanism 12, helping to extend the service life of the lighting device 1 and reducing the noise caused by vibration.

[0071] In some other more specific embodiments, the first oblique teeth 1331 may be replaced by first straight teeth, and the second oblique teeth 1332 may be replaced by second straight teeth.

[0072] Please continue reading Figure 2 and Figure 3 In some more specific embodiments, the driving assembly 134 includes a driving shaft 1341 and a handle 1342. The driving shaft 1341 is connected to the gear assembly 133. The handle 1342 is connected to one end of the driving shaft 1341 away from the gear assembly 133.

[0073] The handle 1342 allows the staff to drive the drive shaft 1341 by simply rotating it, thereby indirectly driving the screw 131 to rotate through the gear assembly 133, so that the staff can easily adjust the precise position of the lighting mechanism 12 without relying on electricity or other external power sources. At the same time, due to the manual operation mode, the staff can adjust the height of the lighting mechanism 12 at any time as needed. Compared with electric or other driving modes, manual operation is more flexible, not limited by power supply, and can adapt to more different working environments and conditions. In addition, since no complex electrical system or external power source is required, the manufacturing cost and operating cost of the lighting device 1 are also reduced.

[0074] In some other more specific embodiments, the drive assembly 134 may also include a motor.

[0075] Please also read Figure 1 and Figure 4 In some embodiments, the lighting mechanism 12 includes a lamp tube 121 and a battery assembly 122. The lamp tube 121 is connected to the driving mechanism 13. The battery assembly 122 is electrically connected to the lamp tube 121.

[0076] The battery assembly 122 is used to power the lamp barrel 121, so that the lighting device 1 does not rely on an external power source or wires, which increases the flexibility and convenience of using the lighting device 1 and improves the scope of application of the lighting device 1. At the same time, the battery assembly 122 is used to power the lamp barrel 121, so that the lighting device 1 can be easily moved to quickly adjust the position of the lighting device 1 as needed. In addition, the battery assembly 122 provides a stable power supply for the lamp barrel 121, avoiding safety hazards caused by fluctuations or interruptions in the external power supply, and ensuring the safety of the lighting device 1 during use.

[0077] In addition, the lighting mechanism 12 may further include a protective cover 123, the lamp tube 121 may be disposed in the protective cover 123, and the battery assembly 122 may be disposed on the top surface of the protective cover 123. The protective cover 123 may protect the lamp tube. The protective cover 123 may be made of transparent glass or transparent plastic, which is not limited here.

[0078] In some other embodiments, the lamp tube 121 may also be powered by electrical wires.

[0079] See also Figure 4 In some specific implementations, the battery assembly 122 includes a storage battery 1221 and a solar panel 1222. The storage battery 1221 is connected to the lamp tube 121. The solar panel 1222 is electrically connected to the storage battery 1221.

[0080] The solar panel 1222 can convert solar energy into electrical energy to charge the storage battery 1221, so that the lighting device 1 can continue to work without an external power supply, making full use of renewable energy and reducing dependence on non-renewable energy. At the same time, the lighting device 1 does not generate pollution and greenhouse gas emissions during operation, meeting environmental protection requirements. In addition, the use of rechargeable storage batteries 1221 also reduces the impact of discarded batteries on the environment.

[0081] In some other more specific embodiments, the battery assembly 122 may be a disposable battery.

[0082] Please refer again Figure 1 In some embodiments, the lighting device 1 further includes a moving mechanism 15 , which is connected to the frame 11 , and is used to drive the frame 11 to move.

[0083] By providing the moving mechanism 15, the lighting device 1 is allowed to be quickly and easily moved when needed, ensuring that the lighting device 1 can be easily moved to a preset position, so that workers do not need to manually move bulky lighting equipment, saving time and improving work efficiency.

[0084] In some other implementations, the lighting device 1 may also be moved manually.

[0085] Please continue reading Figure 1 In some specific embodiments, the moving mechanism 15 includes a moving seat 151 and at least three universal wheels 152. The moving seat 151 is connected to the frame 11 and is located below the frame 11. The at least three universal wheels 152 are all arranged on a side surface of the moving seat 151 away from the frame 11.

[0086] At least three universal wheels 152 can be evenly arranged on the moving seat 151 around the moving axis of the lighting mechanism 12, so that the lighting device 1 can obtain better stability during the movement, which helps to prevent the lighting device 1 from tipping over or tilting during the movement, thereby ensuring the safety of the lighting device 1. At the same time, the outward wheels enable the lighting device 1 to move flexibly in multiple directions, including forward, backward, left and right turns, etc., so that the lighting device 1 can easily adapt to various complex terrains and working environments, and improve work efficiency.

[0087] In some other more specific implementations, the universal wheel 152 can be replaced by a ball bearing.
