[0022] Driving structure 202 includes driving box 204, the inner wall of driving box 204 is rotatably connected with driving turntable 205 through built-in motor, the front side of driving turntable 205 is fixedly installed with eccentric rod 206, the outside of eccentric rod 206 is movably sleeved with deflection shaft 207, the bottom end of deflection shaft 207 is fixedly installed with half tooth disc 208, the bottom end of half tooth disc 208 is engaged with follow-up rack 209, the connecting place of deflection shaft 207 and half tooth disc 208 is rotatably connected with the inner wall of driving box 204, the bottom end of follow-up rack 209 is movably connected with lifting plate 212 through articulated rod 211, the bottom end of lifting plate 212 is fixedly installed with the top end of cleaning ring 203 through connecting rod 213.

[0023] By setting the dustproof structure 2, the air exchange process of the lamp bead structure 1 can be protected by the dust screen 201, so that the dust screen 201 can filter and intercept the dust in the air, thereby avoiding direct contact of dust with the lamp bead structure 1, and cooperating with the driving structure 202 to drive the cleaning ring 203 to clean the outer side of the dust screen 201 in time. Such design not only ensures the filtering efficiency and air permeability of the dust screen 201, but also significantly improves the heat dissipation performance of the LED lamp bead assembly. Through these measures, the service life of the LED lamp bead assembly is prolonged, and the lighting efficiency is stabilized and improved.

[0024] Specifically, the inner wall of the driving box 204 is fixedly installed with a horizontal rod 201, and the follow-up rack 209 is in sliding connection with the surface of the horizontal rod 201.

[0025] In this embodiment, the horizontal rod 201 provides a stable sliding track for the follow-up rack 209, ensuring that the movement of the follow-up rack 209 in the driving box 204 is more stable and accurate. When the follow-up rack 209 slides along the horizontal rod 201, it can smoothly drive the lifting plate 212 to move up and down, thereby achieving lifting control of the cleaning ring 203.

[0026] Specifically, the inner wall of the driving box 204 is fixedly installed with an electric push rod 214, the movable end of the electric push rod 214 is fixedly installed with a locking rack 215, and the locking rack 215 is located above the follow-up rack 209.
