  • the adjusting ring 520 is sleeved on the outer peripheral surface of the base 510, and the adjusting ring 520 sleeve is rotationally matched with the base 510, so that the adjusting ring 520 is sleeved on the base 510 and can rotate freely.
  • a preset number of first magnets are distributed along the circumferential direction of the inner wall surface of the adjustment ring 520. The first magnets are used to inductively cooperate with the Hall sensors 540. Therefore, by rotating the adjustment ring 520, the passage of the two Hall sensors can be changed.
  • the magnetic flux in 540 is also different because the two Hall sensors 540 are arranged in a staggered manner, that is, asymmetrically arranged. Therefore, when the adjustment ring 520 is rotated, the changes in the magnetic flux in the two Hall sensors 540 are also different.
  • the circuit board 530 is disposed on the base 510 and located in the accommodation cavity 511.
  • a control unit (not shown) is integrated on the circuit board 530.
  • the control unit is electrically connected to the two Hall sensors 540 respectively.
  • the control unit is also electrically connected to the light-emitting component 212.
  • the control unit is configured to obtain the change information of the magnetic flux in the two Hall sensors 540 and adjust the brightness of the light emitted by the lamp according to the change information of the magnetic flux.
  • any combination of different implementation modes of the embodiments of the present application can also be performed. As long as they do not violate the ideas of the embodiments of the present application, they should also be regarded as the content disclosed in the embodiments of the present application.
