[0045] Specifically, Figure 1-Figure 3The first embodiment of the utility model is disclosed. In the first embodiment, a hinge portion 31 is provided at one end of the dial member 3, and the hinge portion 31 is in a columnar shape. A paddle portion 32 is provided at the other end of the dial member 3. A hinge hole 211 is provided on the light source board 21. The hinge portion 31 can be inserted into the hinge hole 211. The hinge hole 211 is a round hole. The hinge portion 31 can rotate relative to the hinge hole 211, and the paddle portion 32 can swing around the hinge hole 211. The paddle portion 32 protrudes toward the outside of the housing 12 to facilitate the operation of the paddle portion 32. When in use, by pushing the paddle portion 32, the dial member 3 can swing around the hinge portion 31 to drive the contact member 4.
[0046] See also Figure 2 The dial member 3 also includes a first connecting plate 33 and a connecting portion 34. The first connecting plate 33 is connected between the hinge portion 31 and the paddle portion 32. The connecting portion 34 protrudes from the first connecting plate 33 and passes through the light source board 21. When the dial member 3 is pushed, the connecting portion 34 moves relative to the light source board 21. The contact member 4 is connected to the connecting portion 34, and the contact member 4 can move with the connecting portion 34.
[0047] See also Figure 3 The side wall of the shell 12 is provided with an adjustment hole 121, and the adjustment hole 121 is a long hole. The length direction of the adjustment hole 121 is parallel to the surface of the light source board 21, and the paddle portion 32 passes through the adjustment hole 121 and protrudes from the outer wall of the shell 12. When adjusting, the paddle portion 32 is paddled and the paddle portion 32 moves in the adjustment hole 121. Since the length direction of the adjustment hole 121 is parallel to the surface of the light source board 21, the moving direction of the paddle portion 32 and the connecting portion 34 is parallel to the surface of the light source board 21. The light source board 21 is provided with a sliding hole 212, and the length direction of the sliding hole 212 is parallel to the length direction of the adjusting hole 121, that is, the projection of the extension track of the sliding hole 212 on the plane where the adjusting hole 121 is located will not intersect with the extension track of the adjusting hole 121, and the sliding hole 212 and the adjusting hole 121 are both parallel to the surface of the light source board 21, and the connecting portion 34 protrudes from the sliding hole 212 and can move in the sliding hole 212. Therefore, the connecting portion 34 can make full use of the surface space of the light source board 21 to move without occupying additional moving space, and can reduce the overall volume occupied by the adjusting component 10.
[0048] See also Figure 3In order to limit the adjusted position and improve the operational feel of the adjustment, the inner wall of the sliding hole 212 is provided with a plurality of limiting notches 213, and the limiting notches 213 are recessed toward the inner side of the sliding hole 212, and the edge of the limiting notch 213 is arc-shaped. The plurality of limiting notches 213 are distributed along the length direction of the sliding hole 212 and are connected to each other to form a wave shape, and each limiting notch 213 corresponds to the position on each electrical circuit to which the connecting portion 34 moves, and a limiting protrusion 341 is provided on the side of the connecting portion 34, and the shape of the limiting protrusion 341 corresponds to the shape of the limiting notch 213, and each time the limiting protrusion 341 moves to a position, the limiting protrusion 341 can be buckled into the limiting notch 213 at the corresponding position. After the user uses the dial piece 3 to switch an electrical circuit, the limiting protrusion 341 can be buckled into the limiting notch 213 corresponding to the position of the electrical circuit, which not only limits the limiting protrusion 341 to prevent the connecting part 34 from moving too much or too little to cause a short circuit or poor contact, but also provides vibration feedback and sound feedback for the user's operation after successfully switching the electrical circuit, so as to improve the feel of use and thus enhance the user experience.
[0049] See also Figure 1 In order to guide the movement of the dial member 3 and avoid jamming and tripping, the dial member 3 further includes a guide rod 35, which is arranged at one end of the paddle portion 32 located inside the housing 12. The shape of the guide rod 35 corresponds to the shape of the inner wall of the housing 12, so that the side of the guide rod 35 can abut against the inner wall of the housing 12. When the dial member 3 is moved to drive the contact member 4 to move, the guide rod 35 can slide along the inner wall of the housing 12. The interaction between the guide rod 35 and the housing 12 limits the movement trajectory of the dial member 3, so that the dial member 3 can only move along the inner wall of the housing 12. Specifically, the movement direction of the dial member 3 is horizontal, the inner wall of the housing 12 is an arc surface, the dial member 3 can swing horizontally around the central axis of the housing 12, and the guide rod 35 ensures the swing height and direction of the dial member 3.
[0050] See also Figure 3The contact member 4 includes a second connecting plate 41 and a limiting plate 42. The limiting plates 42 are arranged on both sides of the second connecting plate 41 and protrude from the second connecting plate 41. In the first embodiment, the second connecting plate 41 is fixed to the connecting portion 34 by fasteners 5 such as screws. During installation, the second connecting plate 41 is first fixed to the connecting portion 34 by fasteners 5 such as screws, and the connecting portion 34 can be inserted between the two limiting plates 42. The fasteners 5 limit the contact member 4 in the vertical direction. The cooperation of the limiting plates 42 and the connecting portion 34 limits the contact member 4 in the horizontal direction, so that the contact member 4 can stably follow the movement of the connecting portion 34. The angular deviation generated by the connecting portion 34 when swinging will also be transmitted to the contact member 4.
[0051] See also Figure 2 The contact member 4 also includes a connecting piece 43 and a contact piece 44. The second connecting plate 41 is bent and connected to the connecting piece 43, and the connecting piece 43 is bent and connected to the contact piece 44. Through the mutual bending connection, there is a certain elasticity between the second connecting plate 41 and the contact piece 44, which is conducive to the generation of pre-tightening force between the contact piece 44 and the connecting contact 23, and also facilitates the contact piece 44 to release the current connecting contact 23 and move to the next connecting contact 23. Specifically, the sliding contact (441, 442) is arranged on the contact piece 44, and the sliding contact (441, 442) includes a first moving contact 441 and a second moving contact 442, and the first moving contact 441 and the second moving contact 442 are mutually conductive, and the connecting contact 23 includes a first fixed contact 231 and a second fixed contact 232, and the first fixed contact 231 and the second fixed contact 232 are isolated from each other, and the first fixed contact 231 and the second fixed contact 232 are connected to the same electrical circuit, and the first fixed contact 231 and the second fixed contact 232 constitute a normally open switch of the electrical circuit, and the first moving contact 441 and the second moving contact 442 can contact the first fixed contact 231 and the second fixed contact 232, so that the normally open switch is closed, forming a power-on circuit to power the light source 22. The number of the first fixed contacts 231 and the number of the second fixed contacts 232 are not necessarily equal. By reasonably setting the distance between the first moving contact 441 and the second moving contact 442, when the first moving contact 441 is in contact with the first fixed contact 231, the second moving contact 442 is connected to the second fixed contact 232, and when the first moving contact 441 is in contact with the second fixed contact 232, the second moving contact 442 is connected to the first fixed contact 231.
[0052] See also Figure 3In the first embodiment, the number of the first fixed contact 231 is one, the number of the second fixed contacts 232 is multiple, the first fixed contact 231 is arranged on the side of the sliding hole 212 close to the hinge hole 211, and the second fixed contact 232 is arranged on the side of the sliding hole 212 away from the hinge hole 211, the length of the first fixed contact 231 is greater than the length of each of the second fixed contacts 232, and is less than the total length of all the second fixed contacts 232. The first fixed contact 231 is arranged on the side of the sliding hole 212 close to the hinge hole 211, so that the first moving contact 441 can be in continuous contact with the first fixed contact 231 during the movement. Specifically, the first moving contact 441 and the second moving contact 442 They are respectively arranged at the two ends of the second connecting plate 41, the first moving contact 441 is arranged at one end of the second connecting plate 41 close to the hinge hole 211, and the second moving contact 442 is arranged at one end of the second connecting plate 41 away from the hinge hole 211. By separating the two ends, when the dial member 3 swings, the moving path of the first moving contact 441 is smaller than the path of the second moving contact 442, and the first moving contact 441 can continuously contact with the first fixed contact 231. The moving path of the first moving contact 441 is arc-shaped, and the distribution shape of the first fixed contact 231 is also arc-shaped, and the second moving contact 442 can switch contact between multiple second fixed contacts 232. Each time a second fixed contact 232 is switched, an electrical circuit is switched. In other embodiments, the number of the first fixed contacts 231 may be multiple, and the multiple first fixed contacts 231 are arranged on the side of the sliding hole 212 close to the hinge hole 211. In this case, the shape of the first fixed contact 231 is not an arc, the length of each of the first fixed contacts 231 is less than or equal to the length of each of the second fixed contacts 232, and the first moving contact 441 can switch between the multiple first fixed contacts 231.
[0053] By respectively arranging the first fixed contact 231 and the second fixed contact 232 on both sides of the sliding hole 212, and arranging the first moving contact 441 and the second moving contact 442 at both ends of the second connecting plate 41, and the second connecting plate 41 extending toward the hinge hole 211, the space on the surface of the light source panel 21 can be fully utilized for installation and operation, which can save space and is conducive to the miniaturization and integration of the lamp.

Different from the first embodiment, in the second embodiment, the first fixed contact 231 and the second fixed contact 232 are distributed on the same side of the sliding hole 212, and a single first fixed contact 231 and a single second fixed contact 232 constitute a set of normally open circuit switches. Therefore, there are multiple sets of normally open circuit switches on the light source board 21, and the first moving contact 441 and the second moving contact 442 are respectively arranged on both sides of the same end of the second connecting plate 41. When the contact member 4 moves, the first moving contact 441 and the second moving contact 442 can contact the first fixed contact 231 and the second fixed contact 232, thereby closing the normally open circuit formed by the first fixed contact 231 and the second fixed contact 232. The first fixed contact 231 and the second fixed contact 232 can move to different normally open circuits to close the circuit, thereby realizing the switching of the electrical circuit. By reasonably setting the distance between the first moving contact 441 and the second moving contact 442, when the first moving contact 441 contacts the first fixed contact 231, the second moving contact 442 connects to the second fixed contact 232, and when the first moving contact 441 contacts the second fixed contact 232, the second moving contact 442 connects to the first fixed contact 231.
[0055] By distributing the first fixed contact 231 and the second fixed contact 232 on the same side of the slide hole 212, the radial span of the adjustment component 10 on the light source board 21 can be shortened, and the larger space at the edge of the light source board 21 can be utilized as much as possible, thereby reducing the volume and saving operating space.
[0056] Figure 7-Figure 10 A third embodiment of the utility model is disclosed. Different from the first embodiment, in the third embodiment, the contact member 4 is connected to the connecting portion 34 by plugging, and the distribution of the first fixed contact 231, the second fixed contact 232, the first moving contact 441 and the second moving contact 442 is the same as that of the second embodiment.
[0057] Specifically, see Figure 8 The connecting portion 34 is provided with a connecting hole 342, and the connecting hole 342 penetrates the connecting portion 34. The contact member 4 also includes a plug-in portion 45. The second connecting plate 41 is bent and connected to the plug-in portion 45. The plug-in portion 45 can be inserted into the connecting hole 342. The second connecting plate 41 is fixed to the surface of the connecting portion 34.
[0058] See also Fig.10The contact member 4 includes a plug-in portion 45 and a fixing portion 46, wherein the plug-in portion 45 is located at the end of the fixing portion 46, and the fixing portion 46 is disposed between the second connecting plate 41 and the plug-in portion 45. In order to fix the plug-in portion 45, both sides of the plug-in portion 45 are provided with limiting pieces 451, one end of the limiting piece 451 is connected to the plug-in portion 45, and the other end of the limiting piece 451 is directed toward the fixing portion 46 and extends obliquely toward the outside of the plug-in portion 45. The plug-in portion 45 is used to be inserted into the connecting hole 342 to form a connection, and the limiting piece 451 can be used to form a locking position with the connecting hole 342. An inclined surface 343 is provided in the opening at one end of the connection hole 342, and the inclined direction of the inclined surface 343 is the same as the inclined direction of the limiting piece 451. After the plug-in portion 45 is inserted into the connection hole 342, one end of the limiting piece 451 can abut against the end of the connection portion 34 away from the inclined surface 343, thereby preventing the plug-in portion 45 from coming out. Therefore, the limiting piece 451 and the connection hole 342 constitute a vertical limit, and the inclined surface 343 can facilitate the compression of the limiting piece 451, so that the inclination of the limiting piece 451 is reduced, so that the plug-in portion 45 is inserted into the connection hole 342. After being inserted into the connection hole 342, a limiting boss 461 is provided on the side of the fixing portion 46, and the limiting boss 461 protrudes outward and can abut against the connection hole 342. Therefore, the limiting boss 461 and the connection hole 342 constitute a horizontal limit.
[0059] In the third embodiment, the first fixed contact 231 and the second fixed contact 232 are distributed on the same side of the sliding hole 212, and a single first fixed contact 231 and a single second fixed contact 232 constitute a set of normally open circuit switches, so there are multiple sets of normally open circuit switches on the light source board 21, and the first moving contact 441 and the second moving contact 442 are arranged at the same end of the second connecting plate 41. When the contact member 4 moves, the first moving contact 441 and the second moving contact 442 can contact the first fixed contact 231 and the second fixed contact 232, thereby closing the normally open circuit formed by the first fixed contact 231 and the second fixed contact 232, and the first fixed contact 231 and the second fixed contact 232 can move to different normally open circuits to close the circuit, thereby realizing the switching of the electrical circuit. By reasonably setting the distance between the first movable contact 441 and the second movable contact 442, when the first movable contact 441 contacts the first fixed contact 231, the second movable contact 442 is connected to the second fixed contact 232, and when the first movable contact 441 contacts the second fixed contact 232, the second movable contact 442 is connected to the first fixed contact 231. As in the second embodiment, by distributing the first fixed contact 231 and the second fixed contact 232 on the same side of the slide hole 212, the radial span of the adjustment component 10 on the light source board 21 can be shortened, and the larger space at the edge of the light source board 21 can be used as much as possible, so as to achieve the effect of reducing the volume and saving the operation space.
[0060] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications are also considered to be within the protection scope of the present utility model.
