[0003] However, most dimming and color-adjusting lighting fixtures still rely on DIP switches for color temperature and brightness adjustment. This requires repeatedly toggling the switches, a cumbersome process that hinders ease of use. Furthermore, the complex internal structure of DIP switches results in high production costs, making it difficult to meet the demands of intelligent lighting development. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rotary shifting structure and a lamp having the same structure, which has the advantages of low cost and ease of use.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rotary shifting structure, comprising: Lamp housing; An electric light source board is installed inside the lamp housing; A mounting bracket is fixed to the light source board; A rack is disposed within the fixing frame; A knob is rotatably mounted on one side of the lamp housing and engages with the rack. A spring clip is mounted on the side of the rack near the light source plate; The light source board is provided with a common pad and at least two position contacts. When the knob is rotated, it drives the spring to move so that one end of the spring abuts against the common pad and the other end abuts against the position contact.

[0006] In one embodiment, the light source board is provided with a slot, and the fixing bracket is fixed to the light source board through the slot.

[0007] In one embodiment, the knob includes a rotating part and a first gear, the first gear being engaged with the rotating part and meshing with the rack.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, unless otherwise explicitly specified.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

Example 1

[0024] Embodiment 1 of this utility model is a rotary shifting structure, such as... Figure 1 , Figure 2 and Figure 3 As shown, it includes: a lamp housing 1; an electric light source board 2, installed inside the lamp housing 1; a fixing bracket 3, fixed on the electric light source board 2; a rack 4, installed inside the fixing bracket 3; a knob 5, rotatably inserted through one side of the lamp housing 1 and meshing with the rack 4; and a spring piece 6, installed on the side of the rack 4 near the electric light source board 2.

[0025] Specifically, the lamp housing 1 serves as the supporting foundation; the light source board 2 acts as the circuit carrier, with the spring piece 6 mounted on it to achieve electrical connection and mechanical support; the fixing frame 3 provides stable support for the rack 4 and is tightly integrated with the light source board 2, enhancing the mechanical stability of the entire structure; the spring piece 6, as a key conductive component, is preferably made of highly conductive materials such as copper, beryllium copper, and phosphor bronze.

[0026] Furthermore, such as Figure 3 and 4 As shown, the light source board 2 is provided with a common solder pad 201 and at least two position contacts 202. When the knob 5 is rotated, it drives the spring 6 to move so that one end of the spring 6 abuts against the common solder pad 201 and the other end abuts against the position contact 202.

[0027] Specifically, there are five gear position contacts 202, which are located on both sides of the common pad 201, so that users can select different gear positions by rotating the knob 5. One end of the spring 6 abuts against the common pad 201 to ensure stable current input, while the other end can flexibly switch between the various gear position contacts 202 as the knob 5 is rotated, thereby changing the circuit connection method and realizing the multi-level dimming and color adjustment function of the lamp.

[0028] This invention removes the complex and costly DIP switch and uses the rotation of the knob 5 and rack 4 to connect the spring 6 with the contacts 202 at different positions. This not only makes the operation convenient and enables the lamp to quickly achieve dimming and color adjustment functions, but also reduces production costs and improves production efficiency.

[0029] Furthermore, such as Figure 4 and 5 As shown, the light source board 2 is provided with a slot 203, and the fixing bracket 3 is fixed to the light source board 2 through the slot 203.

[0030] Specifically, there are two slots 203, and the fixing bracket 3 is equipped with corresponding locking blocks to ensure the connection stability between the fixing bracket 3 and the electric light source board 2, and also to simplify the assembly process.

[0031] Furthermore, such as Figure 2 and 3 As shown, the knob 5 includes a rotating part 501 and a first gear 502. The first gear 502 is mounted on the rotating part 501 and is meshed with the rack 4.

[0032] Specifically, the rotating part 501 is located on the outside of the lamp housing 1 for easy operation by the user; the first gear 502 passes through the lamp housing 1 and meshes with the rack 4. The user can rotate the rotating part 501 to drive the rack 4 to move, thereby flexibly adjusting the brightness and color temperature of the light.

[0033] Furthermore, the rotating part 501 has a recess on the side near the first gear 502, and a waterproof ring 7 is fitted on the recess.

[0034] Specifically, the rotating part 501 transforms the traditional lateral movement shifting gear into a rotary shifting gear through gear transmission, and uses an O-ring waterproof seal, which not only optimizes the internal space layout of the lamp but also significantly improves its waterproof performance. In practical applications, when the rotating part 501 rotates, the waterproof seal 7 can tightly fit the recessed area, preventing moisture from entering the lamp housing 1 through the gap between the rotating part 501 and the lamp housing 1, ensuring a sealing effect.

[0035] Furthermore, such as Figure 3 and 6 As shown, the rack 4 includes a support part 401 and a second gear 402. The support part 401 is disposed in the fixed frame 3, and the second gear 402 is fixed on the support part 401. The first gear 502 and the second gear 402 are meshed and connected.

[0036] Specifically, the fixed frame 3 is provided with a square groove, through which the second gear 402 passes and meshes with the first gear 502. The square groove provides a stable motion track for the rack 4, ensuring that the rack 4 maintains linear motion.

[0037] Furthermore, such as Figure 2 and Figure 6 As shown, the spring piece 6 has a bend, and the bottom of the support part 401 has a groove 4011. The bend and the groove 4011 are engaged, so that the spring piece 6 can be firmly engaged with the rack 4, preventing the spring piece 6 from shifting or shaking during movement.

[0038] Furthermore, the fixing frame 3 has multiple positioning holes 301 on one side, and the support part 401 has protrusions 4012 that cooperate with the positioning holes 301.

[0039] Specifically, the number of positioning holes 301 is the same as the number of gear position contacts 202. When the knob 5 is rotated, since the protrusion 4012 and the positioning hole 301 are engaged, the knob 5 can drive the spring piece 6 to engage with the corresponding gear position contact 202 at intervals, thereby ensuring the positional stability of the spring piece 6. Example 2

[0040] The difference between Embodiment 2 and Embodiment 1 of this utility model is that Embodiment 1 fixes the position of the spring piece 6 by engaging the protrusion 4012 with the positioning hole 301, while Embodiment 2 fixes the position of the spring piece 6 by engaging the locking point with the locking block.

[0041] Specifically, the electric light source board 2 has a positioning groove, and the support part 401 abuts against the positioning groove; one side of the positioning groove has a locking point with the same number as the gear contact 202, and the locking point corresponds one-to-one with the gear contact 202. The support part 401 has a locking block that cooperates with the locking point to realize gear switching.

[0042] Furthermore, the mounting bracket 3, rack 4, and knob 5 are all made of insulating material, which can effectively prevent current leakage and improve the safety of use.

[0043] A type of lamp, such as Figure 1 , 2 As shown in Figure 3, it includes a lampshade 8, characterized in that it also includes the above-mentioned rotating shifting structure, with the lampshade 8 covering the lamp housing 1.

[0044] Specifically, a lamp holder 9 is also provided at the end of the lamp housing 1 away from the lamp cover 8. The lamp cover 8, lamp housing 1 and lamp holder 9 fit together tightly to form a closed structure, which can effectively prevent dust and foreign objects from entering, protect the rotating shifting structure and other electronic components inside the lamp housing 1, and extend the service life of the lamp.

[0045] In practical applications, the assembly sequence of a lamp is as follows: First, assemble the rack 4 and the spring 6 together. Then, use the fixing bracket 3 to install the rack 4 and the spring 6 onto the light source board 2. Next, press the light source board 2 into the heat sink. Then, put the waterproof ring 7 on the knob 5 and install it into the lamp housing 1. Then, assemble the lamp head 9. Finally, apply glue and install the lamp cover 8.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
