DETAILED DESCRIPTION

[0034] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be described in detail below with reference to the drawings and specific embodiments.

[0035] Here, it should be noted that, in order to avoid obscuring the present application due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present application are shown in the drawings, and other details not closely related to the present application are omitted.

[0036] In addition, it should also be noted that the term "comprise", "include" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.

[0037] Please refer to FIG. 1, which shows a linear lamp 100 according to an embodiment of the present application. In this embodiment, the linear lamp 100 is a track lamp. The linear lamp 100 comprises an adjusting mechanism 200, a mounting assembly 300 and a lighting assembly 400. The lighting assembly 400 is movably connected to the mounting assembly 300 through the adjusting mechanism 200. The linear lamp 100 according to the present embodiment can make the lighting assembly 400 move in at least two different degrees of freedom to adjust the illumination direction through the adjusting mechanism 200, effectively improving the lighting effect and the convenience of use, and meeting the different lighting needs of users.

[0038] Please refer to FIG. 2-3, the adjusting mechanism 200 includes a first steering mechanism 210 and a second steering mechanism 220 fixedly connected. The first steering mechanism 210 is rotatably connected with the mounting assembly 300, so that the lighting assembly 400 can rotate around a first steering axis as a rotation center. The second steering mechanism 220 is rotatably connected with the lighting assembly 400, so that the lighting assembly 400 rotates around a second steering axis 2202 as a rotation center.

[0039] The second direction is defined as the length extension direction of the lighting assembly 400, that is, the X direction shown in FIG. 1. The first direction is defined as the height extension direction of the lighting assembly 400, that is, the Y direction shown in FIG. 1. The first direction intersects with the second direction to allow the lighting assembly 400 to be adjusted in a manner capable of moving in at least two different degrees of freedom. It can be understood that the intersection of the first direction and the second direction can mean that the projections of the first direction and the second direction on the same plane intersect with each other.

[0040] The first steering mechanism 210 includes a first mounting seat 2101, a first steering axis 2102, and a limiting ring 2103. The first steering axis 2102 is arranged along the first direction and is provided in the first mounting seat 2101. The limiting ring 2103 is arranged at the connection between the first mounting seat 2101 and the first steering axis 2102.

[0041] The limiting ring 2103 is radially protruded from the first steering axis 2102, that is, the limiting ring 2103 is arranged around the first steering axis 2102. The annular surface of the limiting ring 2103 facing the first mounting seat 2101 is a limiting annular surface. The limiting annular surface is configured to abut against the mounting assembly 300, so that the first mounting seat 2101 is accommodated in the accommodation cavity 310 of the mounting assembly 300, and the limiting annular surface and the first steering axis 2102 are exposed to the mounting assembly 300.

[0042] Specifically, please refer to FIG. 4-5, the first steering mechanism 210 is connected with the bottom plate 320 of the mounting assembly 300. The bottom plate 320 is provided with a first connecting hole 3201 corresponding to the position of the first steering mechanism 210. The diameter of the limiting ring 2103 is greater than the diameter of the first connecting hole 3201, and the diameter of the first mounting seat 2101 matches the diameter of the first connecting hole 3201, so that the first mounting seat 2101 can enter the mounting assembly 300 through the first connecting hole 3201, and the limiting annular surface and the first steering axis 2102 are exposed to the mounting assembly 300.

[0043] Further, the linear lamp 100 is provided with a decorative plate 330 on the side of the bottom plate 320 facing the limiting ring 2103. The decorative plate 330 is provided with a second connecting hole 3301 corresponding to the position of the first steering mechanism 210. The diameter and thickness of the limiting ring 2103 match the diameter and thickness of the second connecting hole 3301, so that the limiting ring 2103 is just clamped in the second connecting hole 3301, thereby making the first steering mechanism 210 more stably connected with the mounting assembly 300.

[0044] The linear lamp 100 further comprises a fastening assembly 230. The fastening assembly 230 comprises a rotating shaft fixing frame 2301 arranged in the mounting assembly 300 and a rotating shaft compression ring 2302. The rotating shaft fixing frame 2301 is connected with the bottom plate 320 of the mounting assembly 300, and the rotating shaft compression ring 2302 is connected with the first mounting seat 2101.

[0045] The rotating shaft fixing frame 2301 comprises a rotating hole 2311. The rotating shaft compression ring 2302 is located above the rotating hole 2311. The fastener 2303 is fixedly connected with the rotating shaft compression ring 2302 by extending into the rotating hole 2311.

[0046] In this embodiment, the first steering mechanism 210 is threadedly connected with the fastening assembly 230. The rotating shaft compression ring 2302 comprises two first fixing holes 2321. The first steering mechanism 210 is provided with two second fixing holes 2111 corresponding to the positions of the first fixing holes 2321. The fastener 2303 is a screw. The second fixing holes 2111 are threaded holes. After the first mounting seat 2101 passes through the first connecting hole 3201 and enters the rotating hole 2311, the fastener 2303 passes through the first fixing holes 2321 on the rotating shaft compression ring 2302 and enters the second fixing holes 2111 inside the first steering mechanism 210, thereby threadedly connecting the first steering mechanism 210 and the fastening assembly 230.

[0047] In other embodiments, the first steering mechanism 210 and the fastening assembly 230 can also be connected by other fixing modes, as long as the connection of the first steering mechanism 210 and the mounting assembly 300 can be realized, which is not limited in the application. For example, the first mounting seat 2101 and the rotating shaft compression ring 2302 are clamped.

[0048] Obviously, the diameter of the rotating shaft compression ring 2302 is greater than the diameter of the rotating hole 2311, so that the rotating shaft compression ring 2302 is limited above the rotating shaft fixing frame 2301, thereby connecting the first steering mechanism 210 fixedly connected with the rotating shaft compression ring 2302 on the rotating shaft fixing frame 2301.

[0049] The first positioning member 2312 is arranged at the edge of the rotating shaft fixing frame 2301. When the rotating shaft pressing ring 2302 is placed on the rotating shaft fixing frame 2301, the edge of the rotating shaft pressing ring 2302 abuts against the first positioning member 2312, so that the position of the rotating shaft pressing ring 2302 is quickly determined, and the quick installation of the first steering mechanism 210 is facilitated.

[0050] Further, the rotating shaft pressing ring 2302 is further provided with a positioning groove (not shown). The second positioning member 2112 protrudes from the first mounting seat 2101 towards the rotating shaft pressing ring 2302. When the first mounting seat 2101 is assembled, the second positioning member 2112 is clamped in the positioning groove, so that the first mounting seat 2101 and the rotating shaft pressing ring 2302 are quickly positioned.

[0051] The connection between the rotating shaft pressing ring 2302 and the rotating shaft fixing frame 2301 is only because the diameter of the rotating shaft pressing ring 2302 is greater than the diameter of the rotating hole 2311 of the rotating shaft fixing frame 2301, so that when the rotating shaft pressing ring 2302 is placed on the rotating shaft fixing frame 2301, the rotating shaft pressing ring 2302 will not fall from the rotating hole 2311, and the rotating shaft pressing ring 2302 and the rotating shaft fixing frame 2301 are not fixed. Therefore, the rotating shaft pressing ring 2302 can move relative to the rotating shaft fixing frame 2301.

[0052] The fastener 2303 connects the rotating shaft pressing ring 2302 and the first mounting seat 2101. In fact, the fastener 2303 also passes through the rotating shaft pressing ring 2302 into the range of the rotating hole 2311 of the rotating shaft fixing frame 2301, so that the movement of the rotating shaft pressing ring 2302 is limited to only rotating relative to the rotating shaft fixing frame 2301. That is, the rotating shaft pressing ring 2302 is in rotating connection with the rotating shaft fixing frame 2301.

[0053] Since the rotating shaft pressing ring 2302 is connected with the first mounting seat 2101, when the first steering mechanism 210 rotates relative to the mounting assembly 300 around the first steering shaft 2102, the rotating shaft pressing ring 2302 rotates relative to the rotating shaft fixing frame 2301 synchronously with the first steering mechanism 210. At this time, the first mounting seat 2101 rotates in the rotating hole 2311, and the limiting ring 2103 rotates in the second connecting hole 3301.

[0054] The first steering mechanism 210 is fixedly connected with the second steering mechanism 220. The second steering mechanism 220 is connected with the lighting assembly 400. Therefore, when the first steering mechanism 210 rotates relative to the mounting assembly 300, the lighting assembly 400 is driven to rotate, so that multi-directional lighting is realized.

[0055] The second turning mechanism 220 comprises a second mounting base 2201. The lighting assembly 400 comprises a lighting housing 410. The lighting housing 410 comprises a clamping groove 4101. The second mounting base 2201 is arranged in the clamping groove 4101. The second mounting base 2201 comprises a horizontal connecting surface facing the first turning shaft 2102. The horizontal connecting surface is flush with the outer surface of the lighting housing 410, so that the overall appearance of the lighting assembly 400 is smoother and neater, without protruding parts, and the overall aesthetic of the linear lamp 100 is improved.

[0056] The second turning mechanism 220 further comprises a second turning shaft 2202 arranged at both ends of the second mounting base 2201 in the axial direction, and the second turning shaft 2202 is fixedly connected with the second mounting base 2201.

[0057] Preferably, the second turning mechanism 220 is arranged in the lighting housing 410 of the lighting assembly 400, and the second turning shaft 2202 of the second turning mechanism 220 is rotationally connected with the lighting housing 410 of the lighting assembly 400. In other embodiments, the second turning mechanism 220 can also be arranged outside the lighting housing 410.

[0058] Specifically, the second turning shaft 2202 is rotationally connected with the rotating part 4102 of the lighting assembly 400. In this embodiment, the lighting housing 410 of the lighting assembly 400 is provided with a clamping groove 4101, and two rotating parts 4102 are arranged on both sides of the clamping groove 4101. The second turning shaft 2202 is inserted into the two rotating parts 4102 at both axial ends, and the second turning shaft 2202 can rotate in the rotating part 4102, so that the lighting assembly 400 rotates around the second turning shaft 2202.

[0059] The second mounting base 2201 further comprises an arc-shaped outer wall surface 2212 connected with the horizontal connecting surface and facing away from the first turning shaft 2102. During the rotation of the lighting assembly 400 around the second turning shaft 2202, the distance from any point on the lighting assembly 400 to the second turning shaft 2202 is constant, i.e., the lighting assembly 400 moves along an arc-shaped path. Therefore, the outer wall surface of the second mounting base 2201 is arranged in an arc shape, and the lighting assembly 400 adapts to the arc-shaped outer wall surface 2212 of the second mounting base 2201 during rotation.

[0060] The first direction and the second direction intersect each other, and the first turning shaft 2102 and the second turning shaft 2202 intersect each other, so that the linear lamp 100 realizes adjustment in at least two degrees of freedom.

[0061] The first turning axis 2102 extends in a first direction, so that the lighting assembly 400 can rotate around the first turning axis 2102 relative to the mounting assembly 300. The second turning axis 2202 extends in a second direction, so that the lighting assembly 400 can rotate around the second turning axis 2202 relative to the mounting assembly 300.

[0062] In the present embodiment, the linear lamp 100 is mounted on a ceiling of a top surface. The first turning axis 2102 extends vertically, and the second turning axis 2202 extends horizontally. That is, the first direction is vertical, and the second direction is horizontal. The lighting assembly 400 can rotate around the first turning axis 2102 in the horizontal direction by the first turning mechanism 210. The lighting assembly 400 can be flipped up and down in the vertical direction by the second turning mechanism 220.

[0063] In another embodiment, the linear lamp 100 can also be mounted on a side surface of a wall. The first turning axis 2102 extends horizontally, and the second turning axis 2202 extends vertically. That is, the first direction is horizontal, and the second direction is vertical. The lighting assembly 400 can rotate around the first turning axis 2102 in the vertical direction by the first turning mechanism 210. The lighting assembly 400 can be flipped left and right relative to the side surface of the wall by the second turning mechanism 220.

[0064] In another embodiment, the first turning axis 2102 can also be inclined relative to the mounting surface (ceiling, side surface of the wall, etc.), and the second turning axis 2202 is consistent with the length direction of the lighting assembly 400. The lighting assembly 400 can still rotate around the first turning axis 2102 to meet different lighting needs of the user.

[0065] In the present embodiment, the lighting assembly 400 can rotate 355° around the first turning axis 2102, and the lighting assembly 400 can be flipped 90° to one side around the second turning axis 2202. The user can adjust the direction and angle of the lighting assembly 400 according to different lighting needs.

[0066] As shown in FIGS. 6-7, the lighting assembly 400 is rotated to different directions around the first turning axis 2102. As shown in FIG. 8, the lighting assembly 400 is rotated 90° around the second turning axis 2202.

[0067] As shown in FIGS. 9-10, the lighting assembly 400 is rotated to different directions around the first turning axis 2102, and is also rotated 90° around the second turning axis 2202.

[0068] As shown in FIG. 11, the lighting assembly 400 is rotated around the second turning axis 2202 to a direction in which the light source assembly 420 irradiates obliquely downward.

[0069] In the embodiment, the lighting assembly 400 can be rotated by 90° to the side to achieve the lighting requirement of the linear lamp 100. For example, when the linear lamp 100 needs to illuminate to the left side, the lighting assembly 400 is rotated to the left side around the second rotating shaft 2202 to illuminate. When the linear lamp 100 needs to illuminate to the right side, the lighting assembly 400 is rotated by 180° along the first rotating shaft 2102 to illuminate to the right side.

[0070] In another embodiment, the lighting assembly 400 can be rotated by 90° to both sides around the second rotating shaft 2202, which is not limited in the application.

[0071] In the embodiment, the first rotating mechanism 210 and the second rotating mechanism 220 are integrally arranged, which is simple and clear. The integral arrangement reduces the connecting components between the first rotating mechanism 210 and the second rotating mechanism 220, and reduces the risk of failure caused by loose or failure connection. The integral arrangement of the first rotating mechanism 210 and the second rotating mechanism 220 makes the first rotating mechanism 210 and the second rotating mechanism 220 rotate simultaneously when the lighting assembly 400 rotates around the first rotating shaft 2102. Except that the first rotating shaft 2102 is exposed between the mounting assembly 300 and the lighting assembly 400, the other components of the adjusting mechanism 200 are arranged in the accommodation cavity 310 of the mounting assembly 300 and the lighting housing 410 of the lighting assembly 400, which effectively avoids dust and debris from entering the adjusting mechanism 200, and improves the service life of the linear lamp 100.

[0072] In another embodiment, the first rotating mechanism 210 and the second rotating mechanism 220 are fixedly connected by connecting components. One end of the first rotating shaft 2102 is fixedly connected with the first mounting seat 2101, and the other end is fixedly connected with the second mounting seat 2201.

[0073] The mounting assembly 300 includes an accommodation cavity 310. The accommodation cavity 310 is provided with a locking mechanism 340 and a power supply module 350. The locking mechanism 340 fixes the mounting assembly 300 on the track 500. The power supply module 350 provides power for the linear lamp 100. The lighting assembly 400 includes a lighting housing 410 and a light source assembly 420 arranged in the lighting housing 410.

[0074] The adjusting mechanism 200 is provided with a wire passing hole 240 penetrating the first rotating mechanism 210 and the second rotating mechanism 220 in the axial direction of the first rotating shaft 2102. The first rotating mechanism 210 is in communication with the mounting assembly 300. The second rotating mechanism 220 is in communication with the lighting assembly 400. Therefore, the power supply wire passes through the wire passing hole 240 from the power supply module 350 in the accommodation cavity 310 into the lighting assembly 400, and is electrically connected with the light source assembly 420 to achieve the lighting of the linear lamp 100.

[0075] When assembling the adjusting mechanism 200, the two ends of the second turning shaft 2202 are respectively inserted into the turning parts 4102 at the two ends of the clamping groove 4101 inside the lighting housing 410. The second mounting seat 2201 is clamped in the clamping groove 4101 between the two turning parts 4102. The first mounting seat 2101 passes through the second connecting hole 3301 on the decorative plate 330 and the first connecting hole 3201 on the bottom plate 320 in turn, enters the receiving cavity 310 of the mounting assembly 300 above the first connecting hole 3201, and the first turning shaft 2102 is exposed between the mounting assembly 300 and the lighting assembly 400, wherein the first mounting seat 2101 is connected to the shaft fixing frame 2301 arranged in the receiving cavity 310, and the first mounting seat 2101 is connected to the mounting assembly 300 through the shaft fixing frame 2301.

[0076] When adjusting the illumination direction of the light source assembly 420, the light source assembly 420 can be driven to rotate 355° around the first turning shaft 2102 through the first turning shaft 2102, and the light source assembly 420 can be driven to rotate 90° to one side around the second turning shaft 2202 through the second turning shaft 2202, so as to realize angle adjustment of the linear lamp 100 in two degrees of freedom.

[0077] The adjusting mechanism 200 of the embodiment of the application comprises a first turning mechanism 210 and a second turning mechanism 220. The first turning mechanism 210 comprises a first mounting seat 2101 and a first turning shaft 2102 arranged below the first mounting seat 2101 in a first direction. The first mounting seat 2101 is rotationally connected with the mounting assembly 300, so that the lighting assembly 400 can rotate relative to the mounting assembly 300 with the first turning shaft 2102 as the rotation center. The second turning mechanism 220 comprises a second mounting seat 2201 and a second turning shaft 2202 arranged below the second mounting seat 2201 in a second direction.
