[0035] Please refer to Figures 1 to 3 The embodiment of the present application provides a lighting device 100 for emitting light to realize the lighting function. The lighting device 100 comprises a connecting rod 10, a rotating shaft device 11 and a light emitting module 12.
[0036] The connecting rod 10 is the main frame structure of the lighting device 100, which is used to install and connect other structures of the lighting device 100 such as the light emitting module 12. As a specific example, in the embodiment, the connecting rod 10 is a substantially vertically arranged rod structure. In other embodiments, the connecting rod 10 can also be any structure such as a bent rod, an inclined rod, etc.
[0037] The rotating shaft device 11 is a specific structure for realizing the rotating connection of the light-emitting module 12 and the connecting rod 10. The rotating shaft device 11 is generally rod-shaped as a whole. The rotating shaft device 11 comprises a connecting piece 111, a first rotating shell 112, a first limiting assembly 114, a second rotating shell 113, and a second limiting assembly 115. The connecting piece 111 is used to realize the connection of the rotating shaft device 11 and the connecting rod 10. One end of the connecting piece 111 is connected to the connecting rod 10, and the other end is rotatably connected to the first rotating shell 112. The first limiting assembly 114 is arranged between the connecting piece 111 and the first rotating shell 112, and is used to limit the maximum angle of rotation of the first rotating shell 112 relative to the connecting piece 111 to a first angle. The end of the first rotating shell 112 away from the connecting piece 111 is rotatably connected to the second rotating shell 113, and the second limiting assembly 115 is arranged between the first rotating shell 112 and the second rotating shell 113, and is used to limit the maximum angle of rotation of the second rotating shell 113 relative to the first rotating shell 112 to a second angle. The sum of the first angle and the second angle is not less than 360°. As a specific example, in the present embodiment, the first angle is 30° and the second angle is 340°. In other embodiments, the first angle and the second angle can also be any angle greater than 10° and less than 35°, as long as the sum of the first angle and the second angle is not less than 360 degrees.
[0038] The light-emitting module 12 is a specific structure of the lighting device 100 for emitting light, and is connected to the rotating shaft device 11, thereby realizing the connection with the connecting rod 10.
[0039] Through the above arrangement, when using the lighting device 100, the first rotating shell 112 and / or the second rotating shell 113 can be rotated as needed to change the lighting direction of the light-emitting module 12. Since the sum of the first angle and the second angle is greater than 360°, the maximum rotation angle of the light-emitting module 12 (i.e. the sum of the first angle and the second angle) can exceed 360°, and since the first limiting assembly 114 and the second limiting assembly 115 are provided, the light-emitting module 12 cannot continuously rotate in a certain direction, so that the problem of internal wire entanglement of the light-emitting module 12 due to excessive rotation can be avoided. In summary, the rotation angle of the light-emitting module 12 of the above lighting device 100 is not less than 360°, which can meet the diverse lighting needs of users, while also avoiding the problem of internal wire entanglement of the light-emitting module 12 due to excessive rotation, thereby ensuring the safety of the lighting device 100 and improving the user experience.
[0040] In some embodiments, the lighting device 100 further comprises a base 13, and the connecting rod 10 is connected to the base 13. As a specific example, the base 13 is a disc-shaped structure, and the connecting rod 10 is threadedly inserted into the base 13, which can improve the stability of the lighting device 100 as a whole. The rotating shaft device 11 and the light-emitting module 12 are both provided with a plurality of and the same number of rotating shaft devices 11 and light-emitting modules 12, which are connected one by one. As a specific example, in the present embodiment, the rotating shaft device 11 and the light-emitting module 12 are both provided with three. In other embodiments, the rotating shaft device 11 and the light-emitting module 12 can also be provided with two, four, five, or any other number of rotating shaft devices 11 and light-emitting modules 12.
[0041] In some embodiments, the projections of at least two rotating shaft devices 11 in the vertical direction do not completely coincide. Through the above arrangement, at least two rotating shaft devices 11 in the plurality of rotating shaft devices 11 are staggered, so that at least two light-emitting modules 12 have different illumination directions, which can further improve the illumination range of the lighting device 100 and meet the diverse illumination needs of users.
[0042] Please refer to Figures 3 to 5 In some embodiments, the connecting piece 111 comprises a first threaded connecting portion 1111 and a first rotating insertion portion 1112 connected to each other. The first threaded connecting portion 1111 and the first rotating insertion portion 1112 are both substantially cylindrical. The first rotating shell 112 comprises a first sleeve portion 1121, which is substantially cylindrical. The surface of the first threaded connecting portion 1111 is provided with external threads, and the first threaded connecting portion 1111 is threadedly inserted into the connecting rod 10. The first rotating insertion portion 1112 is rotatably inserted into the first sleeve portion 1121. Through the above arrangement, since the first threaded connecting portion 1111 is threadedly inserted into the connecting rod 10, the threaded connection between the connecting piece 111 and the connecting rod 10 can be achieved, that is, the detachable connection between the rotating shaft device 11 and the connecting rod 10 can be achieved. Since the first rotating insertion portion 1112 is rotatably inserted into the first sleeve portion 1121, the rotating connection between the connecting piece 111 and the first rotating shell 112 can be achieved, that is, the first-order rotation of the rotating shaft device 11 can be achieved.
[0043] Please refer to Figure 4 and Figure 5In some embodiments, the first rotating plug-in part 1112 is provided with a first mounting ring groove 1113 which is a ring-shaped recess. The inner side wall of the first sleeve part 1121 is provided with a second mounting ring groove 1123 which is a ring-shaped recess. The rotating shaft device 11 further comprises a first buckle 116 which is sleeved on the first rotating plug-in part 1112 and simultaneously embedded in the first mounting ring groove 1113 and the second mounting ring groove 1123 to realize the rotating connection of the connecting piece 111 and the first rotating shell 112. The first buckle 116 can be any type of buckle structure such as a C-shaped buckle, a cantilever buckle, a ring-shaped buckle, etc.
[0044] Through the above arrangement, since the first buckle 116 is simultaneously embedded in the first mounting ring groove 1113 and the second mounting ring groove 1123, the first buckle 116 can realize the rotating connection of the first rotating plug-in part 1112 and the first sleeve part 1121, i.e. the rotating connection of the connecting piece 111 and the first rotating shell 112. Moreover, the connection and disassembly operations of the first buckle 116, the connecting piece 111 and the first rotating shell 112 are very simple, which can facilitate the staff to assemble and disassemble the rotating shaft device 11.
[0045] Please refer to Figure 4 、 Figure 5 、 Figure 11 and Figure 13 In some embodiments, the first limiting assembly 114 comprises a first movable piece 1141 and a first positioning piece 1142. As a first specific example, in the present embodiment, the first movable piece 1141 and the first positioning piece 1142 are both spherical structures. In other embodiments, the first movable piece 1141 and the first positioning piece 1142 can also be block-shaped structures or strip-shaped structures or other structures of any shape. The first rotating plug-in part 1112 is provided with a first accommodating ring groove 1114 which is a ring-shaped recess. The inner side wall of the first sleeve part 1121 is provided with two first mounting grooves 1124 which are substantially long and strip-shaped recesses extending along the axial direction of the first sleeve part 1121. The two first mounting grooves 1124 are arranged at intervals along the circumferential direction of the first sleeve part 1121. The first movable piece 1141 is provided with two and located in the two first mounting grooves 1124 respectively, and the first movable piece 1141 is also located in the first accommodating ring groove 1114. The first positioning piece 1142 is fixedly arranged in the first accommodating ring groove 1114 and located between the two first movable pieces 1141, and the first positioning piece 1142 is used to rotate synchronously with the first rotating shell 112, and the two first movable pieces 1141 are located at both ends of the movement path of the first positioning piece 1142.
[0046] With the above arrangement, when the first rotating shell 112 rotates relative to the connecting piece 111, the two first movable pieces 1141 rotate along the first accommodating ring groove 1114 synchronously with the first rotating shell 112, and the positions of the first positioning pieces 1142 in the first accommodating ring groove 1114 remain unchanged. Therefore, when the first rotating shell 112 rotates to the position where the first movable pieces 1141 meet the first positioning pieces 1142, the first movable pieces 1141 cannot continue to rotate with the first rotating shell 112 due to the obstruction of the first positioning pieces 1142, so that the rotation angle of the first rotating shell 112 is limited, thereby limiting the rotation angle of the first rotating shell 112 to the first angle (i.e. the central angle of the arc formed between the two first movable pieces 1141 along the first accommodating ring groove 1114).
[0047] In some embodiments, the first accommodating ring groove 1114 is provided with a first positioning groove 1115 (see Figure 5 ), which is generally a semispherical groove, and the first positioning pieces 1142 are fixedly embedded in the first positioning groove 1115. For example, the first positioning pieces 1142 can be bonded to the inner wall of the first positioning groove 1115, or welded to the inner wall of the first positioning groove 1115. The first positioning groove 1115 can improve the stability of the first positioning pieces 1142, and also avoid the first positioning pieces 1142 from protruding excessively from the first accommodating ring groove 1114 to obstruct the rotation of the first rotating shell 112.
[0048] Please refer to Figure 4 In some embodiments, the rotating shaft device 11 further comprises a first spring 117, which is accommodated in the first sleeve part 1121, one end of the first spring 117 abutting against the first rotating plug part 1112, and the other end abutting against the inner end wall of the first sleeve part 1121. With the above arrangement, the first spring 117 can exert a spring force on the connecting piece 111, thereby increasing the friction between the first rotating shell 112 and the connecting piece 111 when the first rotating shell 112 rotates, i.e. increasing the damping feeling when the first rotating shell 112 rotates, which can avoid the first rotating shell 112 from rotating randomly, and achieve the effect of improving the stability of the first rotating shell 112 when rotating.
[0049] Please refer to Figure 3 、 Figure 4 、 Figures 6 to 9 In some embodiments, the first rotating shell 112 further comprises a second rotating plug part 1122 connected with the first sleeve part 1121, which is generally cylindrical, and the second rotating plug part 1122 is rotatably plugged into the second rotating shell 113. With the above arrangement, the rotating connection between the first rotating shell 112 and the second rotating shell 113 is achieved, thereby realizing the two-stage rotation of the rotating shaft device 11.
[0050] In some embodiments, the second rotating plug-in part 1122 is provided with a third mounting ring groove 1125, which is a ring-shaped groove. The inner side wall of the second rotating shell 113 is provided with a fourth mounting ring groove 1131, which is a ring-shaped groove. The rotating shaft device 11 further comprises a second buckle 118, which is sleeved on the second rotating plug-in part 1122 and is embedded in the third mounting ring groove 1125 and the fourth mounting ring groove 1131 at the same time, so as to realize the rotating connection of the first rotating shell 112 and the second rotating shell 113. The second buckle 118 can be a C-shaped buckle, a cantilever buckle, a ring-shaped buckle or any other type of buckle structure.
[0051] Through the above arrangement, since the second buckle 118 is embedded in the third mounting ring groove 1125 and the fourth mounting ring groove 1131 at the same time, the second buckle 118 can realize the rotating connection of the second rotating plug-in part 1122 and the second rotating shell 113, that is, the rotating connection of the first rotating shell 112 and the second rotating shell 113. Moreover, the connection and disassembly operations of the second buckle 118, the first rotating shell 112 and the second rotating shell 113 are very simple, which can facilitate the staff to assemble and disassemble the rotating shaft device 11.
[0052] Please refer to Figure 4 、 Figure 11 and Figure 12 In some embodiments, the second limiting assembly 115 comprises a second positioning member 1152 and a second movable member 1151. As a specific example, in the present embodiment, the second positioning member 1152 and the second movable member 1151 are both spherical structures. In other embodiments, the second positioning member 1152 and the second movable member 1151 can also be block-shaped structures or strip-shaped structures or any other shape structures. The second rotating plug-in part 1122 is provided with a second accommodating ring groove 1126, which is a ring-shaped groove. The inner side wall of the second rotating shell 113 is provided with a second mounting groove 1132, which is a long strip-shaped groove extending along the axial direction of the second rotating shell 113. The second positioning member 1152 is located in the second mounting groove 1132 and the second accommodating ring groove 1126 at the same time. The second movable member 1151 is fixedly arranged in the second accommodating ring groove 1126, and the second movable member 1151 is used to rotate synchronously with the second rotating shell 113, and the second positioning member 1152 is located on the movement path of the second movable member 1151.
[0053] With the above arrangement, when the second rotating shell 113 rotates relative to the first rotating shell 112, the second movable part 1151 rotates along the second accommodating ring groove 1126 synchronously with the second rotating shell 113, while the position of the second positioning part 1152 in the second accommodating ring groove 1126 remains unchanged. Therefore, when the second rotating shell 113 rotates to the position where the second movable part 1151 meets the second positioning part 1152, the second movable part 1151 cannot continue to rotate with the second rotating shell 113 due to the obstruction of the second positioning part 1152, so that the rotation angle of the second rotating shell 113 can be limited, thereby limiting the rotation angle of the second rotating shell 113 to the second angle (i.e. the central angle corresponding to the arc formed by the two opposite sides of the second movable part 1151 along the second accommodating ring groove 1126).
[0054] In some embodiments, the second accommodating ring groove 1126 is provided with a second positioning groove 1127 (see Figure 6 ), which is generally a semispherical groove, and the second positioning part 1152 is fixedly embedded in the second positioning groove 1127. For example, the second positioning part 1152 can be bonded to the inner wall of the second positioning groove 1127, or welded to the inner wall of the second positioning groove 1127. The second positioning groove 1127 can improve the stability of the second positioning part 1152, and also avoid the second positioning part 1152 from protruding too much from the second accommodating ring groove 1126 to obstruct the rotation of the second rotating shell 113.
[0055] Please refer to Figure 3 、 Figure 4 and Figure 10 , in some embodiments, the rotating shaft device 11 further comprises a universal joint 119, which comprises a rotating connecting part 1191 and a second threaded connecting part 1192 connected together. The rotating connecting part 1191 is generally spherical, and is rotatably accommodated in the second rotating shell 113. The second threaded connecting part 1192 is generally in the shape of a circular rod, and has external threads on its surface. The second threaded connecting part 1192 extends out of the second rotating shell 113 and is threadedly connected to the light-emitting module 12.
[0056] With the above arrangement, since the light-emitting module 12 is connected to the second rotating shell 113 through the universal joint 119, the light-emitting module 12 can rotate around the axis of the rotating shaft device 11, thereby changing the illumination direction of the light-emitting module 12 to meet the diverse lighting needs of users.
[0057] In some embodiments, the second rotating shell 113 is provided with a clearance gap 1133, at least part of the structure of the clearance gap 1133 is located on the end face of the end of the second rotating shell 113 away from the first rotating shell 112, and at least part of the structure of the clearance gap 1133 is located on the side wall of the second rotating shell 113. The universal joint 119 penetrates through the clearance gap 1133, and the universal joint 119 can move to a position in the axial direction of the second rotating shell 113 or in the radial direction of the second rotating shell 113. Through the above arrangement, the clearance gap 1133 can further widen the lighting direction of the light-emitting module 12, thereby further meeting the diverse lighting needs of users.
[0058] Please refer to Figure 4 In some embodiments, the rotating connection part 1191 abuts against the end of the second rotating shell 113 away from the first rotating shell 112, and the rotating shaft device 11 further comprises a second spring 120, the second spring 120 is accommodated in the second rotating shell 113, one end of the second spring 120 abuts against the rotating connection part 1191, and the other end abuts against the first rotating shell 112. Through the above arrangement, the two ends of the rotating connection part 1191 respectively abut against the end of the second rotating shell 113 and the second spring 120, and the two ends of the second spring 120 respectively abut against the rotating connection part 1191 and the first rotating shell 112, so that the second spring 120 can exert a spring force on the first rotating shell 112 and the rotating connection part 1191. Since the rotating connection part 1191 also abuts against the end of the second rotating shell 113, under the action of the spring force of the second spring 120, the rotating connection part 1191 can be tightly pressed in the second rotating shell 113, and the rotating connection part 1191 can be prevented from rotating freely out of the second rotating shell 113, thereby achieving the effect of improving the stability of the universal joint 119 during rotation.
[0059] Please continue to refer to Figure 4 In some embodiments, the rotating shaft device 11 further comprises a spring washer 121, the spring washer 121 is accommodated in the second rotating shell 113, and the spring washer 121 abuts between the universal joint 119 and the second spring 120. In the embodiments of the present application, the spring washer 121 abuts between the rotating connection part 1191 and the second spring 120. The second spring 120 can exert a spring force on the rotating connection part 1191 of the universal joint 119 through the spring washer 121, and the spring washer 121 can increase the contact area with the rotating connection part 1191, so that the spring force acting on the rotating connection part 1191 is more uniform and stable, thereby improving the stability of the second universal joint 119 during rotation.
[0060] In summary, the embodiment of the present application provides a lighting device 100, which comprises a connecting rod 10, a rotating shaft device 11 and a light-emitting module 12, the light-emitting module 12 is connected to the connecting rod 10 through the rotating shaft device 11, and the rotating shaft device 11 comprises a connecting piece 111, a first rotating shell 112, a second rotating shell 113, a first limiting assembly 114 and a second limiting assembly 115. Since the first limiting assembly 114 limits the maximum angle of rotation of the first rotating shell 112 relative to the connecting piece 111 to be a first angle, the second limiting assembly 115 limits the maximum angle of rotation of the second rotating shell 113 relative to the first rotating shell 112 to be a second angle, and the sum of the first angle and the second angle is not less than 360°, therefore the maximum angle of rotation of the light-emitting module 12 is not less than 360°, and the light-emitting module 12 cannot rotate indefinitely to cause the problem of internal wire winding. Therefore, the rotating angle of the light-emitting module 12 of the above-mentioned lighting device 100 is not less than 360°, which can meet the diverse lighting needs of users, and also can avoid the problem of internal wire winding of the light-emitting module 12 due to excessive rotation, thereby ensuring the safety of the lighting device 100 and improving the user experience.
