It should be noted that, in other embodiments, the power supply assembly 400 can also not be provided with the battery 430, and the central shaft 110 can be provided with a power plug, which is electrically connected to the main plate 410 and plugged into an external power source to supply power to the lamp holder 300. In addition, here, the battery 430 can be a dry battery, which needs to be replaced when the power is consumed; the battery 430 can also be a storage battery, which can be repeatedly used by being charged by an external power source. That is, in this application, whether the battery 430 exists and the type of the battery is not limited.

The first electrode 431 is electrically connected to the main plate 410, and the second electrode 432 is electrically connected to the cavity bottom wall 104. The central axis 110 is made of an electrically conductive material, so that the first electrode 431, the second electrode 432, the central axis 110, and the main plate 410 are sequentially electrically connected to form a current loop. In this application, the axial direction of the battery 430 is parallel to the axial direction of the central axis 110, the battery 430 is accommodated in the mounting cavity 103 of the central axis 110, and the contour of the battery 430 is fitted with the cavity contour of the mounting cavity 103, so that the battery 430 is more stably accommodated in the mounting cavity 103. It should be noted that in other embodiments, the central axis 110, the first elastic member 441, and the second elastic member 442 can be made of an insulating material, at which time the electrical connection between the main plate 410 and the battery 430 can be achieved by a soft wire; in addition, the positive and negative electrodes of the battery 430 are not necessarily arranged on opposite sides.

[0052] Preferably, in combination with reference to Figure 4-6 , the battery 430 rotates synchronously with the pipe body 111, in order to further limit the relative shaking and misalignment between the battery 430 and the central axis 110, the power supply assembly 400 includes a first elastic member 441 and a second elastic member 442, Figure 6 It is illustrated that the first elastic member 441 is arranged between the main plate 410 and the first electrode 431 and accumulates elastic force along the axial direction of the central axis 110; the second elastic member 442 is arranged between the cavity bottom wall 104 and the second electrode 432 and accumulates elastic force along the axial direction of the central axis 110. The elastic force released by the first elastic member 441 and the second elastic member 442 can further stably position the battery 430 in the mounting cavity 103. Here, the first elastic member 441 and the second elastic member 442 are both made of an electrically conductive material to achieve a current loop between the main plate 410, the battery 430, and the pipe body 111. It should be noted that, first, when the battery 430 is positioned in the mounting cavity 103 sufficiently stably, in other embodiments, both the first elastic member 441 and the second elastic member 442 can be provided, or only one of them can be provided, or neither of them can be provided, as long as the battery 430 is electrically connected to the main plate 410. In other embodiments, the battery 430 is electrically connected to the main plate 410 by a soft wire or an electrically conductive terminal. That is, in this application, whether the first elastic member 441 and the second elastic member 442 are provided or not is not limited.

[0053] Preferably, in this embodiment, in combination with reference to Figure 4-6The power supply assembly 400 further comprises a metal spring 450 and a fixing disc 460, the fixing disc 460 is connected to the main plate 410 and is circumferentially limited by the main plate 410, the fixing disc 460 is arranged between the main plate 410 and the battery 430, and the fixing disc 460 is provided with a gap 461. Figure 6 As shown, one end of the metal spring 450 is fixed and electrically connected to the main plate 410, and the other end of the metal spring 450 is electrically connected to the inner wall of the tube body 111 after passing through the gap 461. When the lamp cap 300 rotates circumferentially relative to the tube body 111, the fixing disc 460, the main plate 410, the power supply structure 420 and the metal spring 450 rotate synchronously relative to the tube body. It should be noted that in the embodiment, on the one hand, the main plate 410 is electrically connected to the tube body 111 through the metal spring 450, and in other embodiments, the main plate 410 can also be electrically connected to the tube body 111 through a soft wire, a conductive terminal or the like; on the other hand, the metal spring 450 is limited by passing through the gap 461 of the fixing disc 460, which prevents the metal spring 450 from deforming and causing poor electrical contact between the metal spring 450 and the tube body 111 during circumferential rotation. Of course, in the present application, whether the metal spring 450 is provided or not is not limited.

[0054] Preferably, in combination with reference to Figure 4-6 In an embodiment, the gap 461 and the number of metal springs 450 are multiple and equal, that is, the multiple gaps 461 and the multiple metal springs 450 are one-to-one corresponding, and each metal spring 450 passes through a gap 461. The multiple gaps 461 are arranged on the edge of the fixing disc 460 along the circumferential direction of the central axis 110, and the multiple metal springs 450 are distributed along the circumferential direction of the central axis 110 between the main plate 410 and the cavity wall of the mounting cavity 103. The metal spring 450 is pressed between the main plate 410 and the cavity wall of the mounting cavity 103 and accumulates elastic force, and the elastic force released by the metal spring 450 further improves the electrical contact stability between the metal spring 450 and the inner side of the tube body 111. It should be noted that without considering the electrical contact stability of the metal spring 450, the number of metal springs 450 can be multiple or one, and the distribution of the metal springs 450 can be uniform or non-uniform, all of which can realize the electrical connection of the main plate 410 to the tube body 111. That is, in the present application, whether the metal spring 450 is provided or not, the number and distribution of the metal spring 450 are not limited.

[0055] Second embodiment

[0056] In combination with reference to Figure 5 and Figure 8The lighting device 10 of the embodiment and the lighting device 10 of the first embodiment have basically consistent structures, and both can realize that the lamp holder 300, the main plate 410, and the power supply structure 420 can rotate synchronously with the pipe cover 112 relative to the pipe body 111 in the circumferential direction. The difference lies in that the electric connection mode of the main plate 410 and the battery 430 is different. In the embodiment, the main plate 410 is electrically connected to the battery 430 through a soft wire. Specifically, the battery 430 has opposite first and second electrodes 431 and 432, one of which is a positive electrode and the other of which is a negative electrode. The power supply assembly 400 includes a first soft wire 471 and a second soft wire 472. The two ends of the first soft wire 471 are electrically connected to the main plate 410 and the first electrode 431, respectively. The two ends of the second soft wire 472 are electrically connected to the main plate 410 and the second electrode 432, respectively. In this way, the main plate 410, the first soft wire 471, the battery 430, and the second soft wire 472 form a current loop, and the battery 430 realizes power supply for the lighting of the lamp holder 300 through the main plate 410. In the embodiment, the central shaft 110 can be made of insulating material or conductive material.

[0057] Preferably, in the embodiment, the outer side of the battery 430 is provided with a limiting through slot 433 extending from the first electrode 431 to the second electrode 432. The first soft wire 471 is electrically connected to the first electrode 431 after passing through the limiting through slot 433, and the second soft wire 472 is electrically connected to the second electrode 432 after passing through the limiting through slot 433. It should be noted that the limiting through slot 433 is used to guide and position the connection positions of the first soft wire 471 and the second soft wire 472. On the other hand, in the process of circumferential rotation of the main plate 410, the limiting through slot 433 can effectively limit the excessive distortion and damage of the first soft wire 471 and the second soft wire 472. It should be noted that the limiting through slot 433 is only a specific way to limit and fix the first soft wire 471 and the second soft wire 472. In this application, other means for limiting and fixing the first soft wire 471 and the second soft wire 472 should be protected.

[0058] In addition, in combination with reference to Figure 7 and Figure 8 In the embodiment, the pipe body 111 is provided with a blocking ring 116 protruding outward along the radial direction at the outer side of the mounting end 102. The side of the nut 113 away from the support end 101 is abutted by the lower side surface of the blocking ring 116, so as to prevent the nut 113 from being separated from the pipe body 111 in the axial direction of the pipe body 111. It should be noted that the setting of the blocking ring 116 is not limited whether the nut 113 is separated in the axial direction or not.

As mentioned above, the present application is capable of taking many forms of implementation and being practiced in various ways, and the above description is not intended to limit the application in any way, except as required by the appended claims and their equivalents.
