[0039] See also Figures 1 to 6 In order to better understand the lamp 20 of the present application, the lamp 20 is further explained below:

[0040] The lamp 20 of one embodiment includes an eccentric light output adjustment mechanism 10 , a light source component 300 and a face ring component 400 . The toothless end of the first gear component 210 is connected to the light source component 300 , and the toothless end of the second gear component 220 is connected to the face ring component 400 .

[0041] In this embodiment, by using the eccentric light emission adjustment mechanism 10 of the present application, the first gear member 210 and the second gear member 220 are meshed and can rotate with each other, and the toothless end of the first gear member 210 is connected to the light source member 300, and the toothless end of the second gear member 220 is connected to the face ring member 400, so that the light source member 300 can rotate relative to the face ring member 400. When the light source member 300 rotates relative to the face ring member 400, the first gear member 210 will drive the light source member 300 to shift when rotating relative to the face ring member 400, so that the light emission center of the light source member 300 also shifts accordingly, so that the light source member 300 can have a larger light emission adjustment angle while reducing the area where the light path is blocked by the face ring member 400, thereby effectively improving the light emission efficiency of the lamp 20.

[0042] See also Figures 1 to 6 In order to better understand the eccentric light output adjustment mechanism 10 of the present application, the eccentric light output adjustment mechanism 10 is further explained below:

[0043] An eccentric light output adjustment mechanism 10 of one embodiment includes a rotating shaft 100, which is connected to a light source component 300. The light source component 300 rotates around the center of the rotating shaft 100. The eccentric light output adjustment mechanism 10 also includes an eccentric assembly 200. The eccentric assembly 200 includes a first gear component 210 and a second gear component 220. The toothless end of the first gear component 210 is connected to the light source component 300. One end of the rotating shaft 100 is arranged on the first gear component 210, and the toothless end of the second gear component 220 is connected to the face ring component 400. The other end of the rotating shaft 100 is rotatably connected to the second gear component 220, and the toothed end of the first gear component 210 is meshed with the toothed end of the second gear component 220.

[0044] In this embodiment, the toothed end of the first gear member 210 meshes with the toothed end of the second gear member 220 to rotate. Because one end of the rotating shaft 100 is fixedly arranged on the first gear member 210, the other end of the rotating shaft 100 is rotatably connected to the second gear member 220, and the toothed ends of the first gear member 210 and the second gear member 220 have a certain curvature, so that when the first gear member 210 meshes and rotates relative to the second gear member 220, the rotation axis of the first gear member 210 is offset. Further, because the first gear member 210 is fixedly connected to the light source member 300, the first gear member 210 will drive the light source member 300 to shift as a whole, that is, the light emitting center of the light source member 300 will also shift accordingly. In this way, the light source member 300 can have a larger light emitting adjustment angle while reducing the area where the light path is blocked by the face ring member 400, thereby effectively improving the light emitting efficiency of the lamp 20.

[0045] like Figure 3 and Figure 6As shown, in one embodiment, a first connecting column 2110 is provided on a side wall of the first gear member 210, a first through hole 101 is provided at one end of the rotating shaft 100, and the first connecting column 2110 is provided in the first through hole 101, so that one end of the rotating shaft 100 is fixedly connected to the first gear member 210. It can be understood that the first connecting column 2110 is provided in the first through hole 101, which can ensure that one end of the rotating shaft 100 is fixedly connected to the first gear member 210, so that the light source member 300 can be fixedly connected to the eccentric light output adjustment mechanism 10, so that the angle of the light source member 300 can be adjusted by the eccentric light output adjustment mechanism 10, that is, the light output angle adjustment of the lamp 20 is realized by the eccentric light output adjustment mechanism 10.

[0046] like Figure 3 and Figure 6 As shown, in one embodiment, the eccentric assembly 200 further includes a first connecting pin member 230. A second through hole 102 is provided at the other end of the rotating shaft 100, a third through hole 2201 is provided at the toothless end of the second gear member 220, and one end of the first connecting pin member 230 is respectively provided in the second through hole 102 and the third through hole 2201, so that the other end of the rotating shaft 100 is movably connected with the second gear member 220. It can be understood that the eccentric assembly 200 is provided with the first connecting pin member 230 provided in the corresponding second through hole 102 and the third through hole 2201, so that the other end of the rotating shaft 100 is movably connected with the second gear member 220, so that the rotating shaft 100 can rotate relative to the second gear member 220, and because the toothed end of the first gear member 210 and the toothed end of the second gear member 220 can mesh and rotate, the rotation axis of the first gear member 210 is offset. The second gear member 220 is fixedly connected to the face ring member 400, that is to say, the rotation axis of the first gear member 210 is offset relative to the rotation axis of the other end of the rotating shaft 100, driving the light output center of the light source member 300 to be offset. This enables the light source member 300 to have a larger light output adjustment angle while reducing the area of ​​the light path blocked by the face ring member 400, thereby improving the light output efficiency of the lamp 20.

[0047] Furthermore, in this embodiment, the rotation axis of the first gear component 210 is offset downward relative to the rotation axis of the other end of the rotating shaft 100, causing the light output center of the light source component 300 to also be offset downward, further improving the light output adjustment angle of the light source component 300 and reducing the area where the light path is blocked by the face ring component 400, thereby further improving the light output efficiency of the lamp 20.

[0048] like Figure 5As shown, in one embodiment, the rotation angle of the rotating shaft 100 is 0° to 40°. It can be understood that the rotation angle of the rotating shaft 100 is the rotation angle of the eccentric light output adjustment mechanism 10, and because the eccentric light output adjustment mechanism 10 is connected to the light source component 300 and the face ring component 400 respectively, the light source component 300 can rotate relative to the face ring component 400 at an angle of 0° to 40° through the eccentric light output adjustment mechanism 10, that is, the adjustable illumination angle of the lamp 20 is 0° to 40°.

[0049] like Figure 3 , Figure 5 and Figure 6 As shown, in one embodiment, the first gear member 210 further includes a first connecting portion 2120 and a first tooth portion 2130, one end of the first tooth portion 2130 is fixedly connected to one end of the first connecting portion 2120, and the other end of the first connecting portion 2120 is fixedly connected to the light source member 300. It can be understood that the first tooth portion 2130 is used for meshing with the second gear member 220, so that the first gear member 210 and the second gear member 220 are meshed and can rotate relative to each other. One end of the first tooth portion 2130 is fixedly connected to one end of the first connecting portion 2120. Because the first connecting portion 2110 is fixedly connected to the light source member 300, the first gear member 210 is fixedly connected to the light source member 300, and the second gear member 220 is fixedly connected to the face ring member 400, the light source member 300 can rotate relative to the face ring member 400 through the meshing rotation of the first gear member 210 and the second gear member 220, so as to adjust the light output angle of the lamp 20.

[0050] like Figure 3 , Figure 5 and Figure 6 As shown, in one embodiment, the second gear member 220 further includes a second connecting portion 2210 and a second tooth portion 2220. One end of the second tooth portion 2220 is fixedly connected to one end of the second connecting portion 2210, the other end of the second connecting portion 2210 is fixedly connected to the face ring member 400, and the other end of the first tooth portion 2130 is meshed with the other end of the second tooth portion 2220. It can be understood that the second tooth portion 2220 is used to mesh with the first gear member 210, so that the second gear member 220 and the first gear member 210 can be meshed and rotate relative to each other. One end of the second tooth portion 2220 is fixedly connected to one end of the second connecting portion 2210, and the second connecting portion 2210 is fixedly connected to the face ring member 400, so that the second gear member 220 is fixedly connected to the face ring member 400. Because the first gear member 210 is fixedly connected to the light source member 300 , the face ring member 400 can rotate relative to the light source member 300 through the meshing of the second gear member 220 and the first gear member 210 , thereby enabling the lamp 20 to adjust the light output angle.

[0051] like Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment, the light source component 300 includes an outer shell 310, a lamp board 320, a lens body 330 and a rotating shell 340. A first mounting cavity 3101 is provided at one end of the outer shell 310, and the lamp board 320 and the lens body 330 are both arranged in the first mounting cavity 3101. The light-incoming end of the lens body 330 is arranged toward the light-emitting surface of the lamp board 320. One end of the rotating shell 340 is fixedly connected to one end of the outer shell 310, and a rotating connection groove 3401 is provided at the other end of the rotating shell 340, and the other end of the first connecting portion 2120 is fixedly arranged in the rotating connection groove 3101. It can be understood that the outer shell 310 is used to protect the components inside the lamp 20 such as the lamp board 320 and the lens body 330. A first mounting cavity 3101 is provided at one end of the outer shell 310 so that the lamp board 320 and the lens body 330 can be arranged in the outer shell 310, so that the lamp board 320 and the lens body 330 can be protected by the outer shell 310. The light-incoming end of the lens body 330 is arranged toward the light-emitting surface of the lamp board 320, so that the light source emitted by the lamp board 320 can be dispersed to the outside by the lens body 330. By providing a rotating connection groove 3401 at the other end of the rotating shell 340, the other end of the first connecting part 2120 is fixedly arranged in the rotating connection groove 3401, so that the first gear member 210 is fixedly connected to the light source member 300. When the first gear member 210 and the second gear member 220 rotate relative to each other, the first gear member 210 drives the light source member 300 to rotate relative to the face ring member 400, thereby realizing the light output angle adjustment of the lamp 20.

[0052] like Figure 1 , Figure 5 and Figure 6 As shown, in one embodiment, the face ring 400 is sleeved on the other end of the rotating shell 340, and the inner side wall of the face ring 400 is provided with an embedding groove 401, and the second connecting portion 2210 is embedded in the embedding groove 401. It can be understood that the face ring 400 is sleeved on the other end of the rotating shell 340, so that the rotating shell 340 is limited and rotated in the face ring 400, and the embedding groove 401 is provided on the inner side wall of the face ring 400, and the second connecting portion 2210 is embedded in the embedding groove 401, so that the second gear member 220 is fixedly connected with the face ring 400, so that when the first gear member 210 and the second gear member 220 are meshed and rotated, the rotation axis of the connection between the rotating shaft 100 and the second gear member 220 is fixed, and the first gear member 210 is offset, thereby driving the light source member 300 to be offset, that is, the light emitting center of the light source member 300 is also offset, so that the light emitting efficiency of the lamp 20 can be effectively improved.

[0053] like Figure 1As shown, in one embodiment, the outer wall of the face ring 400 is provided with a plurality of connecting members 410. It is understandable that the function of the connecting members 410 is to fix the face ring 400 so that the lamp 20 is fixed in the corresponding working area, and then by adjusting the rotation of the light source member 300 in the lamp 20 relative to the face ring 400, it is possible to ensure that the light source of the lamp 20 is stably irradiated at the designated position.

[0054] like Figure 4 As shown, in one embodiment, the lamp 20 further includes a lampshade 500, and the lampshade 500 is embedded in the face ring member 400. It should be noted that, in this embodiment, the lampshade 500 is a face ring-shaped lampshade with an inclined structure. The main body of the lampshade 500 is tilted downward along the rotation direction of the light source member 300, that is, the main body height of the lampshade 500 decreases along the rotation direction of the light source member 300, so that the area of ​​the light path blocked by the lampshade 500 can be effectively reduced, thereby effectively improving the light output efficiency of the lamp 20.

[0055] like Figure 1 As shown, in one embodiment, the lamp 20 further includes a power connector 600, which is disposed on the outer shell 310 and is electrically connected to the light board 320. It can be understood that the power connector 600 is electrically connected to the light board 320, and the power connector 600 is used to connect an external power source, that is, the power connector 600 can transmit the power of the external power source to the light board 320, so that the light board 320 emits light.

[0056] Compared with the prior art, the utility model has at least the following advantages:

[0057] The toothless end of the first gear part is connected to the light source part and one end of the rotating shaft is fixedly set on the first gear part, the toothless end of the second gear part is connected to the face ring part and the other end of the rotating shaft is rotatably connected to the second gear part, and then the toothed end of the first gear part is meshed and rotated with the toothed end of the second gear part, so that the light source part and the face ring part can rotate relative to each other, that is, the rotation axis of the other end of the rotating shaft is fixed, and the rotation axis of the first gear part is offset, so as to drive the overall offset of the light source part, that is, the light emitting center of the light source part is also offset accordingly, so that the light source part can have a larger light emitting adjustment angle while reducing the area of ​​the light path blocked by the face ring part, thereby effectively improving the light emitting efficiency of the lamp.

[0058] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
