Abstract
A lampshade assembly comprises a lampshade and a connection mechanism. The lampshade has a plurality of lampshade pieces. The connection mechanism has a plurality of connecting rods each of which is respectively attached to the lampshade pieces. The connection mechanism further comprises an upper cap, a first fitting piece, a fitting set and a spring. When the spring is stretched outwardly to separate the upper cap from the first fitting piece and then stack the lampshade pieces. When the lampshade pieces are assembled, the connecting rods radiate around a circle. Since the space occupied by the lampshade assembly is reduced, the packing cost and the transport cost are reduced.
