[0023] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0024] Figure 1 is a structural block diagram of the stepless dimming device of the embodiment of the present application. Figure 1 As shown, the device includes a control device 50 , a touch switch device 80 , an adjustment device 20 and a target light source 30 .

Among them, the first control signal can be a PWM wave signal, and the target light source 30 can be an LED light. In other words, the control device 50 obtains the touch timing signal fed back by the touch switch device 80, and outputs the first control signal corresponding to the first intensity to the adjustment device 20, so that the adjustment device 20 adjusts the brightness of the target light source 30 in response to the first control signal, so as to realize that the stepless dimming device can adjust the brightness of the target light source 30 by touch control during use, so as to be suitable for different auxiliary medical scenarios.
