[0037] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Here, it should be noted that in order to avoid obscuring the present utility model with unnecessary details, only the structures and / or processing steps closely related to the solution of the present utility model are shown in the drawings, while other details less related to the present utility model are omitted.

[0039] In addition, it should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover a non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0040] Please refer to Figure 1As shown, a linear lamp 100 according to an embodiment of the present utility model is a track lamp in this embodiment. The linear lamp 100 includes 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 of this embodiment enables the lighting assembly 400 to move in at least two different degrees of freedom through the adjusting mechanism 200 to adjust the irradiation direction, effectively improving the lighting effect and the convenience of use, and meeting different lighting needs of users.

[0041] Please refer to Figures 2 to 3 As shown, 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 to the mounting assembly 300, enabling the lighting assembly 400 to rotate around the first steering axis. The second steering mechanism 220 is rotatably connected to the lighting assembly 400, enabling the lighting assembly 400 to rotate around the second steering axis 2202.

[0042] Define the second direction as the length extension direction of the lighting assembly 400, such as Figure 1 the X direction shown. Define the first direction as the height extension direction of the lighting assembly 400, such as Figure 1 the Y direction shown. The first direction intersects the second direction to allow the lighting assembly 400 to adjust the irradiation direction in a manner that can move 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 each other.

[0043] 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 disposed on the first mounting seat 2101 and arranged along the first direction. The limiting ring 2103 is provided at the connection between the first mounting seat 2101 and the first steering axis 2102.

[0044] The limiting ring 2103 protrudes radially from the first steering axis 2102, that is, the limiting ring 2103 is arranged around the first steering axis 2102. The ring surface of the limiting ring 2103 facing the first mounting seat 2101 is the limiting ring surface. The limiting ring surface is configured to abut against the mounting assembly 300, so that the first mounting seat 2101 is received in the receiving cavity 310 of the mounting assembly 300, and the limiting ring surface and the first steering axis 2102 are exposed outside the mounting assembly 300.

[0045] Specifically, please refer to Figures 4 to 5As shown, the first steering mechanism 210 is connected to the bottom plate 320 of the mounting assembly 300. A first connection hole 3201 is provided on the bottom plate 320 at a position corresponding to the first steering mechanism 210. The diameter of the limit ring 2103 is larger than that of the first connection hole 3201. At the same time, the diameter of the first mounting seat 2101 matches the diameter of the first connection hole 3201, so that the first mounting seat 2101 can enter the mounting assembly 300 through the first connection hole 3201, while the limit ring surface and the first steering shaft 2102 are exposed outside the mounting assembly 300.

[0046] Furthermore, a decorative plate 330 is provided on the side of the bottom plate 320 of the linear lamp 100 facing the limit ring 2103. A second connection hole 3301 is provided on the decorative plate 330 at a position corresponding to the first steering mechanism 210. The diameter and thickness of the limit ring 2103 match the diameter and thickness of the second connection hole 3301, so that the limit ring 2103 is just clamped in the second connection hole 3301, and further makes the first steering mechanism 210 more stably connected to the mounting assembly 300.

[0047] The linear lamp 100 further includes a fastening assembly 230. The fastening assembly 230 includes a rotating shaft fixing frame 2301 and a rotating shaft pressing ring 2302 disposed inside the mounting assembly 300. Among them, the rotating shaft fixing frame 2301 is connected to the bottom plate 320 of the mounting assembly 300, and the rotating shaft pressing ring 2302 is connected to the first mounting seat 2101.

[0048] The rotating shaft fixing frame 2301 includes a rotating hole 2311. The rotating shaft pressing ring 2302 is located above the rotating hole 2311. A fastener 2303 extends into the rotating hole 2311 and is fixedly connected to the rotating shaft pressing ring 2302.

[0049] In this embodiment, the first steering mechanism 210 is threadedly connected to the fastening assembly 230. The rotating shaft pressing ring 2302 includes two first fixing holes 2321. Two second fixing holes 2111 are provided on the first steering mechanism 210 at positions corresponding to the first fixing holes 2321. The fastener 2303 is a screw. The second fixing hole 2111 is a threaded hole. After the first mounting seat 2101 passes through the first connection hole 3201 and enters the rotating hole 2311, the fastener 2303 passes through the first fixing hole 2321 on the rotating shaft pressing ring 2302 and enters the second fixing hole 2111 inside the first steering mechanism 210, threadedly connecting the first steering mechanism 210 and the fastening assembly 230.

[0050] In other embodiments, the first steering mechanism 210 and the fastening assembly 230 can also be connected by other fixing methods, as long as the connection between the first steering mechanism 210 and the mounting assembly 300 can be achieved, and the present utility model does not limit this. For example, the first mounting seat 2101 and the rotating shaft pressing ring 2302 are snap-connected.

[0051] Obviously, the diameter of the rotating shaft retaining ring 2302 is larger than the diameter of the rotating hole 2311, so that the rotating shaft retaining ring 2302 can be limited above the rotating shaft fixing bracket 2301, and thus the first steering mechanism 210 fixedly connected to the rotating shaft retaining ring 2302 is connected to the rotating shaft fixing bracket 2301.

[0052] A first positioning member 2312 is provided at the edge of the rotating shaft fixing bracket 2301. When the rotating shaft retaining ring 2302 is placed on the rotating shaft fixing bracket 2301, the edge of the rotating shaft retaining ring 2302 abuts against the first positioning member 2312, quickly determining the position of the rotating shaft retaining ring 2302, which is beneficial to the quick installation of the first steering mechanism 210.

[0053] Furthermore, a positioning groove (not shown) is also provided on the rotating shaft retaining ring 2302. The first mounting seat 2101 protrudes towards the rotating shaft retaining ring 2302 to form a second positioning member 2112. When assembling the first mounting seat 2101, the second positioning member 2112 is snapped into the positioning groove to achieve the quick positioning of the first mounting seat 2101 and the rotating shaft retaining ring 2302.

[0054] The connection between the rotating shaft retaining ring 2302 and the rotating shaft fixing bracket 2301 is only because the diameter of the rotating shaft retaining ring 2302 is larger than the diameter of the rotating hole 2311 of the rotating shaft fixing bracket 2301, so that when the rotating shaft retaining ring 2302 is placed on the rotating shaft fixing bracket 2301, the rotating shaft retaining ring 2302 will not fall from the rotating hole 2311, and there is no fixed connection between the rotating shaft retaining ring 2302 and the rotating shaft fixing bracket 2301. Therefore, the rotating shaft retaining ring 2302 can move relative to the rotating shaft fixing bracket 2301.

[0055] With the setting that the fastener 2303 connects the rotating shaft retaining ring 2302 and the first mounting seat 2101, the fastener 2303 actually also passes through the rotating shaft retaining ring 2302 and enters the range of the rotating hole 2311 of the rotating shaft fixing bracket 2301. In this way, the movement of the rotating shaft retaining ring 2302 is limited to only rotating relative to the rotating shaft fixing bracket 2301. That is to say, the rotating shaft retaining ring 2302 is rotatably connected to the rotating shaft fixing bracket 2301.

[0056] Since the rotating shaft retaining ring 2302 is connected to 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 retaining ring 2302 and the first steering mechanism 210 rotate synchronously relative to the rotating shaft fixing bracket 2301. At this time, the first mounting seat 2101 rotates in the rotating hole 2311, and the limiting ring 2103 rotates in the second connection hole 3301.

[0057] The first steering mechanism 210 is fixedly connected to the second steering mechanism 220. The second steering mechanism 220 is connected to the lighting assembly 400. Therefore, when the first steering mechanism 210 rotates relative to the mounting assembly 300, it drives the lighting assembly 400 to rotate, achieving multi-directional lighting.

[0058] The second steering mechanism 220 includes a second mounting base 2201. The lighting assembly 400 includes a lighting housing 410. The lighting housing 410 includes a clamping groove 4101. The second mounting base 2201 is disposed within the clamping groove 4101. The second mounting base 2201 includes a horizontal connection surface facing the first steering shaft 2102. The horizontal connection surface is flush with the outer surface of the lighting housing 410, making the overall appearance of the lighting assembly 400 smoother and neater without any protruding parts, enhancing the overall aesthetic of the linear lamp 100.

[0059] The second steering mechanism 220 further includes a second steering shaft 2202. The second steering shaft 2202 is disposed at both axial ends of the second mounting base 2201, and the second steering shaft 2202 is fixedly connected to the second mounting base 2201.

[0060] Preferably, the second steering mechanism 220 is disposed within the lighting housing 410 of the lighting assembly 400, and the second steering shaft 2202 of the second steering mechanism 220 is rotatably connected to the lighting housing 410 of the lighting assembly 400. In other embodiments, the second steering mechanism 220 may also be disposed outside the lighting housing 410.

[0061] Specifically, the second steering shaft 2202 is rotatably connected to 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 the two rotating parts 4102 are respectively disposed on both sides of the clamping groove 4101. The two axial ends of the second steering shaft 2202 are respectively inserted into the two rotating parts 4102, and the second steering shaft 2202 can rotate within the rotating part 4102, thereby enabling the lighting assembly 400 to rotate around the second steering shaft 2202.

[0062] The second mounting base 2201 further includes an arc-shaped outer wall surface 2212 connected to the horizontal connection surface and facing away from the first steering shaft 2102. During the process of the lighting assembly 400 rotating around the second steering shaft 2202, the distance from any point on the lighting assembly 400 to the second steering shaft 2202 remains unchanged, that is, the lighting assembly 400 will move along an arc-shaped path. Therefore, the outer wall surface of the second mounting base 2201 is set to be arc-shaped, and the lighting assembly 400 is adapted to the arc-shaped outer wall surface 2212 of the second mounting base 2201 when rotating.

[0063] The first direction and the second direction intersect with each other, and the first steering axis 2102 and the second steering axis 2202 intersect with each other, so that the linear lamp 100 realizes adjustment in at least two degrees of freedom.

[0064] Among them, the first steering axis 2102 extends along the first direction, enabling the lighting assembly 400 to rotate circumferentially relative to the mounting assembly 300 with the first steering axis 2102 as the rotation center. The second steering axis 2202 extends along the second direction, enabling the lighting assembly 400 to rotate relative to the mounting assembly 300 with the second steering axis 2202 as the rotation center.

[0065] In this embodiment, the linear lamp 100 is installed on the ceiling of the top surface. The first steering axis 2102 is vertically extended, and the second steering axis 2202 is horizontally extended. That is, the first direction is the vertical direction, and the second direction is the horizontal direction. The lighting assembly 400 can rotate circumferentially in the horizontal direction through the first steering mechanism 210. The lighting assembly 400 can be turned up and down in the vertical direction through the second steering mechanism 220.

[0066] In another embodiment, the linear lamp 100 can also be installed on the side wall. The first steering axis 2102 is horizontally extended, and the second steering axis 2202 is vertically extended. That is, the first direction is the horizontal direction, and the second direction is the vertical direction. The lighting assembly 400 rotates circumferentially in the vertical direction through the first steering mechanism 210. The lighting assembly 400 is turned left and right relative to the side wall through the second steering mechanism 220.

[0067] In another embodiment, the first steering axis 2102 can also be inclined relative to the mounting surface (ceiling, side wall, etc.), and the second steering axis 2202 is consistent with the length extension direction of the lighting assembly 400. The lighting assembly 400 can still rotate with the first steering axis 2102 as the rotation center to meet different lighting needs of users.

[0068] In this embodiment, the lighting assembly 400 can rotate 355° around the first steering axis 2102, and the lighting assembly 400 turns 90° to one side around the second steering axis 2202. Users can adjust the direction and angle of the lighting assembly 400 according to different lighting needs.

[0069] Please refer to Figures 6 to 7 As shown, the lighting assembly 400 rotates around the first steering axis 2102 to different directions. Please refer to Figure 8 As shown, the lighting assembly 400 rotates 90° around the second steering axis 2202.

[0070] Please refer to Figures 9 to 10 As shown, the lighting assembly 400 rotates around the first steering axis 2102 to different directions, and at the same time, rotates 90° around the second steering axis 2202.

[0071] Please refer to Figure 11 As shown, the lighting assembly 400 rotates around the second steering axis 2202 until the light source assembly 420 irradiates obliquely downward.

[0072] In this embodiment, rotating the lighting assembly 400 90° to one side can already meet the lighting requirements of the linear lamp 100. For example, when the linear lamp 100 needs to illuminate to the left, the lighting assembly 400 rotates around the second steering axis 2202 to illuminate to the left. When the linear lamp 100 needs to illuminate to the right, it is only necessary to rotate the lighting assembly 400 that illuminates to the left 180° along the first steering axis 2102.

[0073] In another embodiment, the lighting assembly 400 can rotate 90° to both sides around the second steering axis 2202, and the present utility model does not limit this.

[0074] In this embodiment, the first steering mechanism 210 and the second steering mechanism 220 are integrally arranged, with a simple and clear structure. The integral arrangement reduces the connecting components between the first steering mechanism 210 and the second steering mechanism 220, reducing the risk of failure caused by loose or ineffective connection. The integral arrangement of the first steering mechanism 210 and the second steering mechanism 220 enables the first steering mechanism 210 and the second steering mechanism 220 to rotate simultaneously when the lighting assembly 400 rotates around the first steering axis 2102. Except for the first steering axis 2102 being exposed between the mounting assembly 300 and the lighting assembly 400, the other components of the adjustment mechanism 200 are correspondingly arranged in the receiving cavity 310 of the mounting assembly 300 and the lighting housing 410 of the lighting assembly 400, effectively preventing dust and debris from entering the adjustment mechanism 200 and improving the service life of the linear lamp 100.

[0075] In another embodiment, the first steering mechanism 210 and the second steering mechanism 220 are fixedly connected by connecting components. One end of the first steering axis 2102 is fixedly connected to the first mounting seat 2101, and the other end is fixedly connected to the second mounting seat 2201.

[0076] The mounting assembly 300 includes a receiving cavity 310. A locking mechanism 340 and a power supply module 350 are arranged in the receiving cavity 310. The locking mechanism 340 fixes the mounting assembly 300 on the track 500. The power supply module 350 supplies power to 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.

[0077] The adjustment mechanism 200 is provided with a wire passing hole 240 that penetrates the first steering mechanism 210 and the second steering mechanism 220 in the axial direction of the first steering shaft 2102. The first steering mechanism 210 communicates with the mounting assembly 300. The second steering mechanism 220 communicates with the lighting assembly 400. Therefore, the power cord passes through the wire passing hole 240 from the power supply module 350 in the accommodation cavity 310 and enters the lighting assembly 400, and is electrically connected to the light source assembly 420 to achieve the lighting of the linear lamp 100.

[0078] When assembling the adjustment mechanism 200, the two ends of the second steering shaft 2202 are respectively inserted into the rotating parts 4102 at both ends of the clamping groove 4101 inside the lighting housing 410. The second mounting seat 2201 is then fitted into the clamping groove 4101 between the two rotating parts 4102. The first mounting seat 2101 sequentially passes through the second connection hole 3301 on the decorative plate 330 and the first connection hole 3201 on the bottom plate 320, and enters the accommodation cavity 310 of the mounting assembly 300 where the first mounting seat 2101 is above the first connection hole 3201. The first steering shaft 2102 is exposed between the mounting assembly 300 and the lighting assembly 400. Among them, the first mounting seat 2101 is connected to the rotating shaft fixing frame 2301 arranged in the accommodation cavity 310, and the first mounting seat 2101 is connected to the mounting assembly 300 through the rotating shaft fixing frame 2301.

[0079] When adjusting the irradiation direction of the light source assembly 420, the light source assembly 420 can be driven to rotate 355° around the first steering shaft 2102 through the first steering shaft 2102, and the light source assembly 420 can be driven to rotate 90° to one side around the second steering shaft 2202 through the second steering shaft 2202, realizing the angle adjustment of the linear lamp 100 in two degrees of freedom.

[0080] The adjustment mechanism 200 of the embodiment of the present invention includes a first steering mechanism 210 and a second steering mechanism 220. The first steering mechanism 210 includes a first mounting seat 2101 and a first steering shaft 2102 arranged below the first mounting seat 2101 and along the first direction. The first mounting seat 2101 is rotatably connected to the mounting assembly 300, so that the lighting assembly 400 can rotate relative to the mounting assembly 300 with the first steering shaft 2102 as the rotation center.
