The knob member 310 cooperates with the knob seat 320 so that it can slide up and down and also rotate, and the control component can control the parameters of the lamp body 200. When the knob member 310 is in the first position, the first rotation position sensor 420 works and can sense the rotation angle of the knob member 310, so that the corresponding parameter can be controlled and adjusted through the control circuit board 410. After pressing or sliding the knob member 310 to the second position, the second rotation position sensor 430 works and can sense the rotation angle of the knob member 310, so that the control circuit board 410 can control another parameter for adjustment, so that rotating a knob member 310 can control multiple reference adjustments, thereby reducing the number of knob assemblies 300, facilitating user control, and facilitating the assembly of the desk lamp.

[0032] Specifically, the base 100 supports the lamp body 200, and the knob assembly 300 is arranged on the upper surface of the base 100.

The first conductive part 440 is fixedly connected to the sliding member 313, and the second conductive part 450 is arranged on the knob cover 311. Deflecting the knob cover 311 can drive the first conductive part 440 and the second conductive part 450 to abut and connect. Specifically, the knob cover 311 is for the user to operate to rotate or press.

The second conductive part 450 is fixedly connected to the sliding member 313 so that it can move up and down with the knob member 310. On the basis of the up and down movement, pressing the circumference of the middle part of the knob cover 311 can make the knob cover 311 deflect relative to the universal joint 312. During deflection, the first conductive part 440 and the second conductive part 450 can abut and connect, thereby realizing the control circuit connection. The specific circuit structure is a conventional technical means and is not described in detail here.

Specifically, a conductive ring 441 may be provided on the annular circuit board, and when the knob member 310 is rotated, the second conductive part 450 can rotate along the conductive ring 441 and remain above the conductive ring 441. When the knob cover 311 is pressed, the second conductive part 450 can be pressed down to the conductive ring 441, thereby achieving parameter adjustment.

[0036] Reference Figure 2 and Figure 4 In some embodiments of the present invention, the sliding member 313 is provided with a threaded column, the universal joint 312 is provided with a threaded hole, the threaded column passes through the annular circuit board and is threadedly connected with the threaded hole, and the annular circuit board is pressed against the universal joint 312.

The first resistor ring 421 and the second resistor ring 431 are arranged on the inner wall of the sliding groove 321 at intervals, and the first conductive contact 422 and the second conductive contact 432 are arranged on the knob 310 at intervals. In the first position, the first conductive contact 422 abuts against the first resistor ring 421, and in the second position, the second conductive contact 432 abuts against the second resistor ring 431. Specifically, the first and second rotation position sensors 430 calibrate the rotation angle by measuring the resistance value. The specific measurement structure is a prior art and is not described in detail herein. The first resistor ring 421 and the second resistor ring 431 can be arranged on the inner wall of the sliding groove 321 at intervals in the upper and lower directions. The knob member 310 is arranged on the side wall of the sliding groove 321 to arrange the first conductive contact 422 and the second conductive contact 432 in the upper and lower directions, and the spacing between the first conductive contact 422 and the second conductive contact 432 is smaller than the spacing between the first resistor ring 421 and the second resistor ring 431, so that when the first conductive contact 422 is connected to the first resistor ring 421, the second conductive contact 432 and the second resistor ring 431 will not be connected, and when the second conductive contact 432 and the second resistor ring 431 are connected, the first conductive contact 422 will not be connected to the first resistor ring 421, so that the first rotation position sensor 420 and the second rotation position sensor 430 can be switched.

[0038] In some embodiments of the present invention, the first rotation position sensor 420 is used to control the illumination brightness of the lamp body 200, and the second rotation position sensor 430 is used to control the illumination color temperature of the lamp body 200. Specifically, the user can turn the knob 310 to adjust the illumination brightness, and when the color temperature needs to be adjusted, the user only needs to press down the knob 310 and turn it to adjust the color temperature, which is more convenient to operate.

[0039] Reference Figures 2 to 3In some embodiments of the present invention, a first driving member 500 is further included. The lamp body 200 includes a bracket 210 and a lamp head 220. The lamp head 220 is disposed on the bracket 210. The bracket 210 is rotatably disposed on the base 100. The first driving member 500 is disposed on the base 100 and is electrically connected to the control circuit board 410. The first driving member 500 is transmission-connected to the bracket 210. The first rotational position sensor 420 is used to control the illumination brightness of the lamp head 220. The second rotational position sensor 430 can control the first driving member 500 according to the rotation angle of the knob member 310, so that the first driving member 500 drives the bracket 210 to rotate a corresponding angle. Specifically, the first driving member 500 can be set as a motor, which is arranged in the base body 100. The bracket 210 can be horizontally rotatably connected to the base body 100. The first driving member 500 is transmission-connected to the bracket 210. The first driving member 500 can drive the bracket 210 to rotate. In actual use, the knob member 310 is located in the first position. At this time, rotating the knob member 310 can adjust the brightness through the first rotation position sensor 420. When it is necessary to adjust the horizontal illumination direction of the lamp body 200, the knob member 310 can be pressed to slide to the second position, and the knob member 310 can be rotated. At this time, the second rotation position sensor 430 can sense and enable the control circuit board 410 to control the operation of the first driving member 500. The first driving member 500 can control the rotation angle of the lamp body 200. It can be understood that the second rotation position sensor 430 can be calibrated to the same rotation angle of the knob member 310 as the rotation angle of the bracket 210, so that the user can adjust the illumination angle conveniently without manually adjusting the lamp body 200, which is convenient to use.

[0040] Reference Figures 2 to 3 In some embodiments of the present invention, a second driving member 600 is further included. The lamp head 220 is rotatably disposed on the bracket 210. The second driving member 600 is disposed on the bracket 210, and the second driving member 600 is transmission-connected to the lamp head 220. The abutment between the first conductive portion 440 and the second conductive portion 450 can control the second driving member 600 so that the second driving member 600 drives the lamp head 220 to rotate. Specifically, the lamp head 220 and the bracket 210 can be pivotally connected so that the lamp head 220 can be flipped up and down to adjust the illumination angle. The second driving member 600 can be a motor. The second driving member 600 can be connected to the lamp head 220 in a transmission manner to drive the lamp head 220 to flip up and down. When the first conductive part 440 is connected to the second conductive part 450, the second driving member 600 can be controlled to operate. In actual use, the knob member 310 can not only rotate to adjust the parameters, but also press the edge of the knob cover 311 to deflect it to the first conductive part 440 and the second conductive part 450 to connect, thereby realizing the up and down flipping control of the lamp head 220. It can be understood that in the initial position, the second conductive part 450 can be arranged in the front and rear positions of the knob cover 311, so that the up and down flipping of the lamp head 220 can be more intuitively controlled.
