Different connecting contacts 23 are connected to different electrical circuits, so that different connecting contacts 23 output different currents, and the contact piece 32 can contact the connecting contacts 23, and when the dial piece 31 moves, the dial piece 31 can drive the contact piece 32 to slide between different connecting contacts 23, thereby changing the current input to the light source 22, so as to achieve the effect of changing the current to adjust the light output parameters.

[0033] The beneficial effects of the embodiments of the present invention are as follows:

[0034] The dimming lamp based on the dial plate in the embodiment of the present invention is provided with a shell 1, a light source assembly 2 and an adjustment assembly 3, wherein the light source assembly 2 includes a light source board 21 and a light source part 22, the shell 1 includes a shell 12, the light source board 21 is fixed in the shell 12, and the adjustment assembly 3 includes a dial part 31 and a contact part 32, the dial part 31 is slidably connected to the light source board 21, the dial part 31 can slide relative to the shell 12, and in the process of sliding, it can drive the contact part 32 to slide between the connection contacts 23 of the light source board 21, the connection contacts 23 are connected to the power supply mechanism, and the contact part 32 can contact different connection contacts 23. Since the power supply currents of different connection contacts 23 are different, the light emission effect of the light source part 22 can be adjusted. The method of changing the contacts by sliding is relatively simple in structure. The contacts are arranged on the light source board 21 without protruding structures, so the overall structure can be simplified and the overall space can be reduced. In addition, it is relatively simple to connect the dial member 31 and the contact member 32, so it also has the advantage of easy installation.

[0035] In an embodiment of the invention, the contact member 32 is a spring sheet, which has deformation and recovery capabilities. After being subjected to a certain degree of external force, it can be deformed and restored to its original shape. In order to facilitate conductivity, the spring sheet used is a metal spring sheet. Using a spring sheet as the contact member 32 can simplify the overall structure, save installation space and usage space, and facilitate its use of recovery ability to produce continuous and stable contact with the connection contact 23 while facilitating its use of deformation ability to switch between different connection contacts 23. The contact member 32 is provided with sliding contacts (441, 442), and the sliding contacts (441, 442) can contact the connection contact 23. The contact member 32 as a whole can conduct electricity. Therefore, by sliding the sliding contacts (441, 442) between different connection contacts 23, different power supply circuits can be switched.

[0036] Specifically, referring to FIG2 , the dial member 31 includes a connecting portion 311 and a paddle portion 312. The connecting portion 311 is provided with a connecting hole 313, into which the contact member 32 can be inserted to form a fixed position. Therefore, the dial member 31 can drive the contact member 32 to move. The contact member 32 is connected to the dial member 31 by plugging, resulting in a simple structure that is easy to install and remove. One end of the paddle portion 312 is connected to the connecting portion 311, and the other end protrudes toward the outside of the housing 12. When adjustment is required, the connecting portion 311 and the contact member 32 within the connecting portion 311 can be driven to move by toggling the paddle portion 312. A sliding hole 211 is provided on the light source board 21, and the length direction of the sliding hole 211 is parallel to the length direction of the adjusting hole 122, that is, the projection of the extension trajectory of the sliding hole 211 on the plane where the adjusting hole 122 is located will not intersect with the extension trajectory of the adjusting hole 122. The sliding hole 211 and the adjusting hole 122 are both parallel to the surface of the light source board 21, and the connecting portion 311 can be inserted into the sliding hole 211 and slide in the slider 211. The connecting portion 311 forms a sliding connection with the sliding hole 211, and the sliding hole 211 can limit the sliding direction of the connecting portion 311.

[0037] The side wall of the shell 12 is provided with an adjustment hole 122, and the adjustment hole 122 is a long hole. The length direction of the adjustment hole 122 is parallel to the surface of the light source board 21. The paddle portion 312 passes through the adjustment hole 122 and protrudes from the outer wall of the shell 12. In this way, when adjusting, the paddle portion 312 is pried, and the paddle portion 312 will move in the adjustment hole 122. Since the length direction of the adjustment hole 122 is parallel to the surface of the light source board 21, the moving direction of the paddle portion 312 and the connecting portion 311 will be parallel to the surface of the light source board 21. Preferably, in an embodiment of the present invention, the connecting portion 311 moves on the surface of the light source board 21, so that the connecting portion 311 can make full use of the surface space of the light source board 21 to move without occupying additional moving space, thereby reducing the overall volume occupied by the adjustment component 3.

[0038] Referring to Figure 2, in order to further guide the movement of the dial member 31 and avoid jamming and tripping, the dial member 31 also includes a guide rod 314, which is provided at one end of the paddle portion 312 located inside the shell 12. The shape of the guide rod 314 corresponds to the shape of the inner wall of the shell 12, so that the side of the guide rod 314 can abut against the inner wall of the shell 12. When the dial member 31 is dialed to drive the contact member 32 to move, the guide rod 314 can slide along the inner wall of the shell 12. The interaction between the guide rod 314 and the shell 12 limits the movement trajectory of the dial member 31, so that the dial member 31 can only move along the inner wall of the shell 12. Specifically, the movement direction of the dial member 31 is horizontal, the inner side wall of the housing 12 is an arc-shaped surface, the dial member 31 can swing horizontally around the central axis of the housing 12, and the guide rod 314 ensures the swing height and direction of the dial member 31.

[0039] Furthermore, referring to FIG4 , a first limiting card plate 315 and a second limiting card plate 316 are provided on the connecting portion 311, and the first limiting card plate 315 and the second limiting card plate 316 protrude from the surface of the connecting portion 311, and the first limiting card plate 315 and the second limiting card plate 316 are respectively located on opposite sides of the connecting hole 313, wherein the first limiting card plate 315 is located on the side of the connecting hole 313 close to the center of the shell 12, and the second limiting card plate 316 is located on the side of the connecting hole 313 away from the center of the shell 12, the first limiting card plate 315 and the second limiting card plate 316 can be inserted into the sliding hole 211, and the first limiting card plate 315 and the second limiting card plate 316 are respectively located on opposite sides of the connecting hole 313. The first limit card plate 315 and the second limit card plate 316 are respectively abutted against the opposite sides of the sliding hole 211 and can move along the surface of the light source board 21. The sliding hole 211 limits the first limit card plate 315 and the second limit card plate 316, so that when the code dial 31 moves, the first limit card plate 315 and the second limit card plate 316 can slide under the limit of the sliding hole 211.

[0040] The adjusting hole 122 limits the movement of the paddle portion 312, and the sliding hole 211 limits the movement of the connecting portion 311 through the first limiting card plate 315 and the second limiting card plate 316, and the length direction of the sliding hole 211 is parallel to the length direction of the adjusting hole 122. While ensuring that both ends of the dial member 31 can move smoothly in the same direction, the sliding hole 211, the first limiting card plate 315 and the second limiting card plate 316 also ensure that the contact member 32 located in the connecting hole 313 can continue to abut against the light source board 21.

[0041] 4 , a first buckling platform 317 is provided at the end of the first limiting card plate 315. The first buckling platform 317 protrudes in a direction away from the connecting hole 313 and tilts from a side away from the center of the shell 12 toward a side close to the center of the shell 12. A second buckling platform 318 is provided at the end of the second limiting card plate 316. The second buckling platform 318 protrudes in a direction away from the connecting hole 313 and tilts from a side close to the center of the shell 12 toward a side away from the center of the shell 12. The first buckling platform 317 The longitudinal section of the first and second snap-fit ​​platforms 317 and 318 is a triangle, and the inclination directions of the two are opposite. After the first limiting card plate 315 and the second limiting card plate 316 are inserted into the sliding hole 211, the first snap-fit ​​platform 317 and the second snap-fit ​​platform 318 can both abut against the surface of the light source board 21. Therefore, when the first limiting card plate 315 and the second limiting card plate 316 slide in the sliding hole 211, the sliding hole 211 forms a horizontal limit, and the first snap-fit ​​platform 317 and the second snap-fit ​​platform 318 form a vertical limit.

[0042] The arrangement of the first snap-fit ​​platform 317 and the second snap-fit ​​platform 318 also facilitates installation and disassembly. Specifically, when connecting the dial piece 31 and the light source board 21, the first snap-fit ​​platform 317 and the second snap-fit ​​platform 318 are first brought into contact with the sliding hole 211 and inserted into the sliding hole 211. Since the first snap-fit ​​platform 317 protrudes in the direction away from the connecting hole 313 and tilts from the side away from the center of the shell 12 to the side close to the center of the shell 12, and the second snap-fit ​​platform 318 protrudes in the direction away from the connecting hole 313 and tilts from the side close to the center of the shell 12 to the side away from the center of the shell 12, the first snap-fit ​​platform 317 and the second snap-fit ​​platform 318 constitute an insertion structure. The width gradually narrows from the position of the first limiting card plate 315 and the second limiting card plate 316 toward the top, so it is convenient to insert into the sliding hole 211, and the sliding hole 211 has a reaction force on the first snap-fit ​​platform 317 and the second snap-fit ​​platform 318. The distance between the first snap-fit ​​platform 317 and the second snap-fit ​​platform 318 narrows as the depth of insertion into the sliding hole 211 increases, thereby further improving the convenience of inserting into the sliding hole 211. After being fully inserted into the sliding hole 211, the first snap-fit ​​platform 317 and the second snap-fit ​​pass over the sliding hole 211 and abut against the surface of the light source board 21, forming a vertical limit, and the first limiting card plate 315 and the second limiting card plate 316 abut against both sides of the sliding hole 211, forming a horizontal limit. When disassembly is required, the first snap-fitting platform 317 and the second snap-fitting platform 318 are squeezed from the outside to make them close to each other, and the width of the insertion structure formed by the first snap-fitting platform 317 and the second snap-fitting platform 318 becomes smaller, so that the vertical limit can be loosened, so that the first snap-fitting platform 317 and the second snap-fitting platform 318 can be pulled out.

[0043] 4 , the contact member 32 includes a plug-in portion 321 and a fixed portion 322, the plug-in portion 321 is located at the end of the fixed portion 322. In the embodiment of the present invention, the contact member 32 is a single component, and the plug-in portion 321 and the fixed portion 322 are made by an integral molding process such as local stamping and local bending, wherein both sides of the plug-in portion 321 are provided with a limiting piece 323, one end of the limiting piece 323 is connected to the plug-in portion 321, and the other end of the limiting piece 323 is extended toward the fixed portion 322 and obliquely toward the outside of the plug-in portion 321, the plug-in portion 321 is used to insert the connecting hole 313 to form a connection, and the limiting piece 323 can be used The connecting portion 313 is locked with the connecting hole 313, and a slope 319 is provided in the opening at one end of the connecting hole 313. The inclination direction of the slope 319 is the same as the inclination direction of the limiting piece 323. After the plug-in portion 321 is inserted into the connecting hole 313, one end of the limiting piece 323 can abut against the end of the connecting portion 311 away from the slope 319, thereby preventing the plug-in portion 321 from falling out. Therefore, the limiting piece 323 and the connecting hole 313 constitute a vertical limit, and the slope 319 can facilitate the extrusion of the limiting piece 323, so that the inclination degree of the limiting piece 323 is reduced, which facilitates the entire insertion of the plug-in portion 321 into the connecting hole 313. After being inserted into the connecting hole 313 , a limiting boss 324 is provided on the side of the fixing portion 322 . The limiting boss 324 protrudes outward and can abut against the connecting hole 313 , so that the limiting boss 324 and the connecting hole 313 constitute a horizontal limit.

The first fixed contact 231 and the second fixed contact 232 are equivalent to the switches of the normally open electrical circuit, and the current of the electrical circuit formed by each group of the connecting contacts 23 is different. In the process of the dial member 31 driving the contact member 32 to move, the first moving contact 327 and the second moving contact 328 can contact the first fixed contact 231 and the second fixed contact 232 of each group, so that different electrical circuits form a path, and the power supply current of the light source member 22 is changed by switching different electrical circuits to achieve a regulation effect. The number of the first fixed contacts 231 and the second fixed contacts 232 are not necessarily equal. By reasonably setting the distance between the first movable contact 327 and the second movable contact 328, when the first movable contact 327 contacts the first fixed contact 231, the second movable contact 328 is connected to the second fixed contact 232, and when the first movable contact 327 contacts the second fixed contact 232, the second movable contact 328 is connected to the first fixed contact 231.
