The movable connection design of the opening and closing blocking members 18 allows the dimming unit 5 to flexibly adjust its position during operation. A number of groups of electromagnets 20 are fixedly arranged on the inner walls of the two groups of opening and closing blocking members 18 close to each other. These electromagnets 20 are used to control the opening and closing states of the opening and closing blocking members 18.

One end of a return spring 23 is fixedly connected to the guiding column 22, and the other end of the return spring 23 is fixedly connected to the inner wall of the arc-shaped groove 21. The design of the arc-shaped grooves 21 enables the guiding column 22 to move freely therein. The setting of the return spring 23 can provide elastic support during the adjustment process, enabling the guiding column 22 to move freely in the arc-shaped grooves 21 and automatically reset after adjustment, thereby maintaining the stability and accuracy of the dimming unit.

[0046] Working principle: When it is necessary to adjust the range irradiated by the light source, start the driving motor 8 to drive the driving gear 9 to rotate. At this time, the driving gear 9 drives the driving push member 4 to move along the lamp holder 1 through the rack 25, and then pushes the dimming unit 5 to shield the LED lamp board 2, so as to realize the adjustability of the range irradiated by the light source. When it is necessary to further finely adjust the range of the light, since the mutually repulsive electromagnets 20 are symmetrically installed on the two sets of opening and closing blocking members 18, by controlling the start of the electromagnets 20, the adjacent electromagnets 20 on the two sets of opening and closing blocking members 18 can push the two sets of opening and closing blocking members 18 to rotate around the fixed frame 15. At this time, the guide post 22 slides along the arc-shaped groove 21 and stretches the return spring 23. By controlling the sequential start of several groups of electromagnets 20 in the above manner, the range of the two sets of opening and closing blocking members 18 can be controlled. When it is necessary to close the two sets of opening and closing blocking members 18, just turn off the electromagnets 20. Under the action of the return spring 23, the two sets of opening and closing blocking members 18 can be closed.
