[0034] Therefore, according to the linkage dimming device 100 of the embodiment of the present invention, a structure combining a first bracket 10, a first rotating shaft 20, a second bracket 30 and a first driving member 40 is adopted, and the upper ends of the first module 200 and the second module 300 are respectively connected to the two ends of the second bracket 30, and the lower ends of the first module 200 and the second module 300 are respectively connected to the two ends of the first bracket 10, so that the rotation angles of the first module 200 and the second module 300 along the horizontal direction and the vertical direction can be adjusted respectively, and it has the advantages of simple structure and easy use.
