[0037] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] See also Figure 1As shown, the present invention discloses a lamp 100 that can adjust the brightness of the lamp 100 without requiring a dimming button on its exterior. In this embodiment, the lamp 100 is preferably a desk lamp. This is because the light source of a desk lamp is closest to the user and can easily damage the user's eyesight, thus requiring brightness adjustment.

[0039] Please combine Figure 2 and Figure 7 As shown, the lamp 100 includes a shell 1, a light source assembly 2, a driving assembly 3, a rotating disk 4 and a dimming element 5. The light source assembly 2 is at least partially housed inside the shell 1 and emits light toward the periphery of the shell 1. The driving assembly 3 is assembled inside the shell 1, and the driving assembly 3 is electrically connected to the light source assembly 2 through a cable 31, so that it can drive the light source assembly 2 to emit light toward the periphery of the shell 1. The rotating disk 4 is located outside the shell 1, and is rotatably connected to the light source assembly 2 and the dimming element 5, so as to drive the dimming element 5 to rotate when it rotates. The dimming element 5 is movably connected to the driving assembly 3, and is configured to be able to rotate under the rotation drive of the rotating disk 4, so as to adjust the output power of the driving assembly 3, and then adjust the light output brightness of the light source assembly 2.

[0040] In this embodiment, the driver assembly 3 is preferably a circuit board, which is used to output voltage to drive the light source assembly 2 to emit light. The dimming element 5 is preferably a potentiometer because it can accurately control the voltage output by the driver assembly 3 to achieve a stepless dimming effect without the need to design gears. Of course, in other embodiments, the dimming element 5 can also be other electrical components, which is not limited to this.

[0041] The housing 1 includes a first housing 11, a second housing 12, and an adapter 13 fixedly connected to the second housing 12. The adapter 13 connects the first and second housings 11, 12 and is located within the first and second housings 11, 12. A through-hole 110 is defined within the housing 1, extending from top to bottom. This through-hole 110 extends from the first housing 11 to the adapter 13 and second housing 12.

[0042] In this embodiment, the first shell 11 and the second shell 12 are an upper shell and a lower shell assembled from top to bottom. Of course, in other embodiments, the first shell 11 and the second shell 12 can also be a left shell and a right shell assembled from left to right, or the shell 1 itself can be integrally formed, without limitation.

[0043] The adapter 13 includes a connecting portion 131 that penetrates into the first housing 11 and a positioning portion 132 that fits within the second housing 12. The connecting portion 131 engages with the light source assembly 2 to maintain relative stationary contact with the housing 1. The positioning portion 132 is fixedly connected to the driving assembly 3 to position the driving assembly 3.

[0044] Please combine Figure 3 As shown, preferably, a rib 1313 is provided on the bottom side of the adapter 131 facing the light source assembly 2, and the rib 1313 is used to engage with the light source assembly 2. Of course, in other embodiments, the adapter 131 and the light source assembly 2 can also be fixed with threads, which is not limited to this.

[0045] The adapter portion 131 further defines a first opening 1311 and a second opening 1312 , both of which are in communication with the second housing 12 and the first housing 11 .

[0046] Please combine Figure 4 and Figure 5 As shown, a receiving cavity 1310 is formed between the first opening 1311 and the second housing 12. The receiving cavity 1310 extends through the adapter 131. A first assembly area 13101 and a second assembly area 13102 are provided within the receiving cavity 1310. The first assembly area 13101 is located near the light source assembly 2, and the second assembly area 13102 is located near the dimming element 5. The receiving cavity 1310, the first assembly area 13101, and the second assembly area 13102 provide space for connecting the rotating disk 4 and the dimming element 5. The second opening 1312 allows the cable 31 to pass through.

[0047] The lamp 100 also includes an auxiliary assembly disposed within the receiving cavity 1310. The auxiliary assembly comprises a first auxiliary member 61 mounted in the first mounting area 13101 and a second auxiliary member 62 mounted in the second mounting area 13102. A fixing member 63 is disposed between the second auxiliary member 62 and the dimming member 5. In this embodiment, the rotating disk 4 and the dimming member 5 are fixedly connected via a rotating shaft. The first auxiliary member 61 and the second auxiliary member 62 serve as two opposing bearings, ensuring smoother rotation of the shaft. The fixing member 63 is a nut fixedly connected to the shaft, preventing the shaft from disengaging from the two bearings during rotation.

[0048] The light source assembly 2 is at least partially housed inside the first shell 11 and includes a light source portion 21 exposed to the outside of the top of the first shell 11 and an assembly portion 22 assembled inside the first shell 11. The light source portion 21 is movably connected to the rotating disk 4 so that the rotating disk 4 can rotate relative to the light source portion 21.

[0049] Please combine Figure 6 As shown, a through-hole 210 is provided on the side of the light source portion 21 facing the rotating disk 4. The through-hole 210 is connected to the through-hole 110. A groove 211 is provided on the periphery of the through-hole 210, which is recessed away from the rotating disk 4. The groove 211 is connected to the through-hole 210, and a stop block 212 is provided in the groove. The stop block 212 is used to limit the rotation range of the rotating disk 4.

[0050] The light source unit 21 comprises a light source board 213, a lower cover 214, and an upper cover 215. The lower cover 214 and upper cover 215 sandwich the light source board 213. The upper cover 215 is movably connected to the rotating disk 4. The lower cover is equipped with a lens that faces the light beads on the light source board 213. Light emitted by the light source board 213 passes through the lens and is emitted toward the outer periphery of the housing 1.

[0051] The bottom of the assembly part 22 is provided with a limiting groove 221 corresponding to the convex rib 1313, and the convex rib 1313 is engaged in the limiting groove 221 so that the assembly part 22 and the adapter part 131 of the adapter 13 remain relatively stationary. In this embodiment, the limiting groove 221 is provided at the bottom of the upper cover 215. This is because the upper cover 215 and the lower cover 214 leave a gap directly due to clamping the light source board 213. The gap is for the outer wall of the adapter part 131 to be inserted, that is, the upper cover 215 and the lower cover 214 also clamp the outer wall surface of the adapter part 131 at the same time. Therefore, the bottom of the upper cover 215 can be inserted into the bottom of the adapter part 131 and engaged with the convex rib 1313 in the adapter part 131.

[0052] Please combine Figure 7 As shown, the rotating disk 4 includes a transmission part 41 and a rotating part 42. The rotating part 42 is movably connected to the upper cover 215 of the light source assembly 2. The transmission part 41 is inserted into the through cavity 110 as a rotating shaft and is connected to the dimming component 5. In this embodiment, the rotating part 42 is made of metal material, which blocks the light emitted by the light source assembly 2 so that the light emitted by the light source assembly 2 is emitted toward the outer periphery of the shell 1. The rotating part 42 can be designed in a certain shape to serve as a decoration for the lamp 100 as a whole. At the same time, the brightness of the light source assembly 2 can be adjusted by the user manually rotating the rotating part 42, which is more convenient to operate.

[0053] The rotating portion 42 has a recessed receiving groove 420 on the side facing the first housing 11, and the light source portion 21 is received in the receiving groove 420. Preferably, the receiving groove 420 is circular, and the light source portion 21 is also circular as a whole. This configuration allows the rotating portion 42 to rotate relative to the light source portion 21.

[0054] A stopper 411 is provided within the receiving groove 420. This stopper 411 is designed to abut against the stopper 212 of the light source unit 21. When the rotating disk 4 rotates until the stopper 411 abuts against the stopper 212, the rotating disk 4 stops rotating. At this point, the brightness of the light source assembly 2 reaches its maximum or minimum. Specifically, the stopper 411 is located on the transmission unit 41 and is positioned within the receiving groove 420.

[0055] Of course, it is possible to set the rotating disk 4 to stop rotating and the brightness of the light source assembly 2 to reach the maximum when the rotating disk 4 rotates clockwise until the limit block 411 abuts the stop block 212. Alternatively, it is possible to set the rotating disk 4 to stop rotating and the brightness of the light source assembly 2 to reach the maximum when the rotating disk 4 rotates counterclockwise until the limit block 411 abuts the stop block 212. There is no limitation on this.

[0056] An annular assembly groove 410 is provided on the outer peripheral wall of the transmission part 41, and the lamp 100 also includes a stop ring 8 assembled in the assembly groove 410. When the transmission part 41 is inserted into the through cavity 110, the stop ring 8 is also accommodated in the groove 211 at the same time. The stop ring 8 is preferably a rubber ring, which is used to provide damping for the rotation of the transmission part 41. With this arrangement, when there is not enough external force applied to the rotating part 42, the rotating part 42 cannot rotate, thereby avoiding the occurrence of accidental touch. At the same time, when the external force applied to the rotating part 42 disappears, the rotating part 42 can also stop rotating in time, giving the user a good user experience.

[0057] The lamp 100 is further provided with a follower 7, the ends of which are connected to the dimming element 5 and the transmission part 41, respectively, and the follower 7, the dimming element 5 and the transmission part 41 remain relatively stationary. In this way, the dimming element 5 and the transmission part 41 are connected by the follower 7, so that a stable transmission structure is formed between the transmission part 41, the follower 7 and the dimming element 5.

[0058] To sum up, the lamp 100 of the present invention is provided with a movably connected dimming element 5 on the driving component 3, and the dimming element 5 and the rotating disk 4 are transmission-connected, so that when the rotating disk 4 located outside the shell 1 is rotated, the dimming element 5 located inside the shell 1 can be driven to rotate, so as to adjust the output power of the driving component 3 and then adjust the brightness of the lamp 100.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
