The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] like Figures 1 to 4 As shown, some embodiments of this application provide a lamp, mainly used to adjust the lighting range of the lamp and control the length of the lamp to meet the user's needs, adapt to different scenarios, and improve the flexibility and versatility of the lamp.

[0045] The lamp has a first direction X, which refers to the length direction of the lamp.

[0046] The lighting fixture includes a housing 100, a first lamp group 200, a second lamp group 300, a driving device 400, and a transmission device 500.

[0047] The housing 100 defines a receiving cavity 110. The shape of the housing 100 can be at least one of the following: cuboid, polygonal prism, annular, or disc-shaped, and can be specifically set according to the actual situation.

[0048] The first lamp group 200 and the second lamp group 300 are slidably connected to the housing 100. It should be noted that the first lamp group 200 and the second lamp group 300 slide relative to the housing 100 along the first direction X.

[0049] It is worth noting that in some embodiments, the first lamp group 200 and the second lamp group 300 slide in the same direction relative to the housing 100, that is, the first lamp group 200 and the second lamp group 300 move synchronously in opposite directions to adjust the illumination position of the first lamp group 200 and the second lamp group 300; in other embodiments, the first lamp group 200 and the second lamp group 300 slide in opposite directions relative to the housing 100, that is, the first lamp group 200 and the second lamp group 300 slide in opposite directions along the first direction X.

[0050] The drive device 400 and the transmission device 500 are respectively disposed in the receiving cavity 110. The transmission device 500 is connected to the output end 410 of the drive device 400. That is, when the drive device 400 is started, the output end 410 of the drive device 400 can drive the transmission device 500 to move.

[0051] The drive device 400 can be a stepper motor or a geared motor. In this embodiment, the drive device 400 is a geared motor.

[0052] The first lamp group 200 and the second lamp group 300 are respectively connected to the transmission device 500 so that the transmission device 500 can drive the first lamp group 200 and the second lamp group 300 to move along the first direction X during the movement, thereby adjusting the position of the first lamp group 200 and the second lamp group 300 relative to the housing 100, so as to adjust the lighting range and light effect of the lamp.

[0053] In this embodiment, the moving directions of the first lamp group 200 and the second lamp group 300 are reversed along the first direction X. This allows control over the length between the first lamp group 200 and the second lamp group 300, which not only adjusts the illumination range of the first lamp group 200 and the second lamp group 300, but also adjusts the length of the lamps, improving the uniformity of the illumination. Depending on the length of the lamps, different lighting effects can be created to meet the user's lighting needs for different scenarios and enhance the user experience.

[0054] like Figures 1 to 3 As shown, in some embodiments of this application, the lamp includes a second direction Y intersecting the first direction X.

[0055] In this embodiment, the second direction Y is perpendicular to the first direction X, and the second direction Y is the width direction of the housing 100.

[0056] The housing 100 is provided with a first guide rail 120 and a second guide rail 130 through it along the first direction X, that is, the axis of the first guide rail 120 and the axis of the second guide rail 130 are parallel to the first direction X.

[0057] Furthermore, the first guide rail 120 and the second guide rail 130 are spaced apart along the second direction Y. It can be understood that, along the second direction Y, the first guide rail 120 is disposed on one side of the housing 100, and the second guide rail 130 is disposed on the other side of the housing 100, that is, the first guide rail 120 and the second guide rail 130 are disposed on two opposite sides of the housing 100 along the second direction Y.

[0058] In this embodiment, the first lamp group 200 and the first guide rail 120 are slidably connected so that the first guide rail 120 provides guidance and limiting function for the first lamp group 200, thereby ensuring the stability and smoothness of the first lamp group 200 during sliding relative to the housing 100. The second lamp group 300 and the second guide rail 130 are slidably connected so that the second guide rail 130 provides guidance and limiting function for the second lamp group 300, thereby ensuring the stability and smoothness of the second lamp group 300 during sliding relative to the housing 100.

[0059] Therefore, it is understandable that the first lamp assembly 200 is at least partially housed in the first guide rail 120, and the second lamp assembly 300 is at least partially housed in the second guide rail 130.

[0060] like Figure 3 and Figure 4 As shown, in some embodiments of this application, the transmission device 500 includes a driving wheel 510, a driven wheel 520, and a synchronous belt 530, wherein the driving wheel 510 is rotatably connected to the housing 100, and the driven wheel 520 is rotatably connected to the housing 100.

[0061] The driving wheel 510 is connected to the output end 410 of the driving device 400, and the driven wheel 520 is connected to the driving wheel 510 through the synchronous belt 530. That is, when the driving device 400 is running, the output shaft of the driving device 400 drives the driving wheel 510 to rotate synchronously, and the driving wheel 510 drives the transmission device 500 to rotate, and the transmission device 500 drives the driven wheel 520 to rotate synchronously during operation.

[0062] Since the first lamp group 200 and the second lamp group 300 are respectively connected to the transmission device 500, the transmission device 500 can drive the first lamp group 200 and the second lamp group 300 to move along the first direction X during the rotation of the transmission device 500, thereby adjusting the length of the lamp and adjusting the lighting range and light effect of the lamp.

[0063] In addition, the inner wall of the receiving cavity 110 is provided with a first rotating shaft 140 and a second rotating shaft 150. The driving wheel 510 is rotatably sleeved on the first rotating shaft 140, so that the first rotating shaft 140 provides support, rotation and limiting function for the driving wheel 510, thereby ensuring the stability and smoothness of the driving wheel 510 during rotation in the receiving cavity 110. The driven wheel 520 is rotatably sleeved on the second rotating shaft 150, so that the second rotating shaft 150 provides support, rotation and limiting function for the driven wheel 520, thereby ensuring the stability and smoothness of the driven wheel 520 during rotation in the receiving cavity 110.

[0064] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the lamp includes a third direction Z that intersects the first direction X and the second direction Y in pairs.

[0065] In this embodiment, the first direction X, the second direction Y, and the third direction Z are all perpendicular to each other.

[0066] The first lamp assembly 200 includes a first connecting tube 210 and a plurality of first lamp bodies 220. The first lamp bodies 220 are disposed along the third direction Z on the side of the first connecting tube 210 away from the housing 100. The connection method between the first lamp body 220 and the first connecting tube 210 includes at least one of snap-fit, adhesive, threaded connection and bolt connection to ensure the stability of the connection between the first lamp body 220 and the first connecting tube 210.

[0067] The second lamp assembly 300 includes a second connecting tube 310 and a plurality of second lamp bodies 320. The second lamp bodies 320 are disposed along the third direction Z on the side of the second connecting tube 310 away from the housing 100. The connection method between the first lamp body 220 and the first connecting tube 210 includes at least one of snap-fit, adhesive, threaded connection and bolt connection to ensure the stability of the connection between the first lamp body 220 and the first connecting tube 210.

[0068] It is understandable that the number of the first lamp body 220 and the number of the second lamp body 320 can be any number of two or more values, and can be set according to the actual situation.

[0069] By increasing the number of the first lamp body 220 and the second lamp body 320, the lighting brightness and lighting effect of the lamp can be improved.

[0070] In addition, multiple first lamp bodies 220 are arranged at intervals along the first direction X, and the distance between two adjacent first lamp bodies 220 can be specifically set according to the actual situation. Multiple second lamp bodies 320 are arranged at intervals along the first direction X, and the distance between two adjacent second lamp bodies 320 can be specifically set according to the actual situation.

[0071] In this embodiment, multiple first lamp bodies 220 are arranged at equal intervals along the first direction X, and multiple second lamp bodies 320 are arranged at equal intervals along the first direction X. This not only improves the overall aesthetics of the lamp, but also enhances the uniformity of light distribution and brightness.

[0072] like Figure 3 As shown, in some embodiments of this application, the first connecting pipe 210 is provided with a first connecting member 600 connected to the synchronous belt 530 on the side facing the synchronous belt 530. The first connecting pipe 210 is fixedly connected to the side of the synchronous belt 530 near the first connecting pipe 210 through the first connecting member 600, so that the synchronous belt 530 can drive the first connecting pipe 210 to move synchronously along the first direction X through the first connecting member 600 during rotation, thereby driving the first lamp body 220 to move along the first direction X.

[0073] The second connecting pipe 310 is provided with a second connecting member 700 on the side facing the synchronous belt 530, which is connected to the synchronous belt 530. The second connecting pipe 310 is fixedly connected to the side of the synchronous belt 530 near the second connecting pipe 310 through the second connecting member 700, so that the synchronous belt 530 can drive the second connecting pipe 310 to move synchronously along the first direction X through the second connecting member 700 during rotation, thereby driving the second lamp body 320 to move along the first direction X.

[0074] In this embodiment, the first connector 600 and the second connector 700 are respectively disposed on two opposite sides of the synchronous belt 530 along the third direction Z, and there is a gap between the first connector 600 and the second connector 700, so as to ensure that the synchronous belt 530 can drive the first connector 600 and the second connector 700 to move synchronously in opposite directions along the first direction X during rotation, thereby driving the first lamp group 200 and the second lamp group 300 to move in opposite directions along the first direction X through the first connector 600 and the second connector 700 respectively.

[0075] It is understandable that by setting the first connector 600 and the second connector 700 alternately, the timing belt 530 can ensure the smoothness and stability of the first connector 600 and the second connector 700 moving along the first direction X during rotation, thereby ensuring the smoothness and stability of the first lamp group 200 and the second lamp group 300 moving along the first direction X.

[0076] like Figure 3 As shown, in some embodiments of this application, the lamp includes a first limiter 800 and a second limiter 900 disposed in the receiving cavity 110. The first connecting pipe 210 is provided with a first limiting member 1000 on the side near the first limiter 800, so that the first limiter 800 limits the first limiting member 1000. The second connecting pipe 310 is provided with a second limiting member 1100 on the side near the second limiter 900, so that the second limiter 900 limits the second limiting member 1100.

[0077] In this embodiment, the first lamp group 200 and the second lamp group 300 have an extended position and a retracted position, respectively. It should be noted that the extended position refers to the first lamp group 200 and the second lamp group 300 moving away from the housing 100 along the first direction X under the drive of the transmission device 500. That is, the first connecting pipe 210 extends from the first guide rail 120, and the second connecting pipe 310 extends from the second guide rail 130. At this time, the positions of the first lamp group 200 and the second lamp group 300 relative to the housing 100 are the extended positions, and the length of the lamp is at its maximum along the first direction X. The retracted position refers to the first connecting pipe 210 being completely housed in the first guide rail 120, and the second connecting pipe 310 being completely housed in the second guide rail 130. At this time, the positions of the first lamp group 200 and the second lamp group 300 relative to the housing 100 are the retracted positions, and the length of the lamp is at its minimum along the first direction X.

[0078] In the extended position, the first limiting member 1000 abuts against the first limiting device 800, thereby limiting the first limiting member 1000 to prevent movement and ensuring the accuracy and stability of the first lamp group 200 and the second lamp group 300 in the extended position. It should be noted that the first limiting device 800 is electrically connected to the drive device 400. When the first limiting member 1000 abuts against the first limiting device 800, the first limiting device 800 is triggered and sends a control command to the drive device 400 to stop, thus ensuring the stability, safety, and accuracy of the first lamp group 200 and the second lamp group 300 in the extended position.

[0079] In the retracted position, the second limiting member 1100 abuts against the second limiting device 900, thereby limiting the movement of the second limiting member 1100 and ensuring the accuracy and stability of the first lamp group 200 and the second lamp group 300 in the retracted position. It should be noted that the second limiting device 900 is electrically connected to the drive device 400. When the second limiting member 1100 abuts against the second limiting device 900, the second limiting device 900 is triggered and sends a control command to the drive device 400 to stop, thus ensuring the stability, safety, and accuracy of the first lamp group 200 and the second lamp group 300 in the retracted position.

[0080] In this embodiment, the first limiter 800 and the second limiter 900 are any one of a capacitive touch sensor, a resistive touch switch, a proximity sensor, a photoelectric switch, a pressure sensor, and a Hall switch, and can be specifically set according to the actual situation.

[0081] In some embodiments of this application, the distance between the first limiter 800 and the first limit member 1000 is L1, and the distance between the second limiter 900 and the second limit member 1100 is L2. In the extended position, L1 = 0, L2 > 0, L1 + L2 = L, and L > L2 > 0.

[0082] At the contracted position, L2 = 0, L1 > 0, L1 + L2 = L, and L > L1 > 0.

[0083] The value range of L can be set according to actual needs. It can be understood that the maximum distance between the first limiter 800 and the first limit member 1000 is equal to the maximum distance between the second limiter 900 and the second limit member 1100. That is to say, during the process of the drive device 400 controlling the transmission device 500 to rotate, the first lamp group 200 and the second lamp group 300 can be driven by the transmission device 500 to move synchronously in opposite directions along the first direction X. Moreover, the moving distance of the first lamp group 200 and the second lamp group 300 relative to the outer shell is always equal. This not only ensures the stability of the first lamp group 200 and the second lamp group 300 during the movement, but also improves the aesthetics of the lamp during the extension or retraction process.

[0084] like Figure 3 As shown, in some embodiments of this application, the lamp includes a controller disposed in the receiving cavity 110, and the drive device 400 is electrically connected to the controller to control the start or stop of the drive device 400 through the controller.

[0085] In this embodiment, the controller can connect to a mobile terminal or remote control via a wireless control signal. That is, the user can wirelessly connect to the controller via a mobile terminal to send control commands to the controller. The controller receives the control commands and executes them after recognizing them, thereby realizing remote control of the lighting fixtures and improving the convenience for the user during use.

[0086] like Figure 3 As shown, in some embodiments of this application, the first lamp group 200 and the second lamp group 300 are electrically connected to the controller (not shown in the figure) to control the opening or closing of the first lamp group 200 and the second lamp group 300 through the controller.

[0087] In this embodiment, the first lamp body 220 and the second lamp body 320 are electrically connected to the controller so that the controller can control the first lamp body 220 and the second lamp body 320 to turn on or off.

[0088] In some embodiments, the controller can individually control any one of the plurality of first lamp bodies 220 and any one of the plurality of second lamp bodies 320. That is, the controller can control any one or more of the plurality of first lamp bodies 220 to start or stop, and the controller can control any one or more of the plurality of second lamp bodies 320 to start or stop, so that the user can adjust the number of first lamp bodies 220 and second lamp bodies 320 turned on according to actual needs, thereby adjusting the overall brightness of the lamp.

[0089] In addition, users can control the first lamp body 220 or the second lamp body 320 in different positions via mobile terminal or remote control to adjust the light effect, so as to obtain a better lighting effect suitable for different scenes and living atmospheres, enhance the versatility and convenience of the lamps during use, and improve the user experience.

[0090] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0091] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0092] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
