Abstract
A lampshade assembly includes a rib retaining unit and a plurality of shade members. The rib retaining unit includes a lower rib retaining member, an upper rib retaining member superimposed on the lower rib retaining member, and a fastening member for securing together the lower and upper rib retaining members. The connecting rib has a distal end retained removably on the rib retaining unit. The shade members are disposed adjacent to each other, and cooperate to form a lamp containing space when the distal ends of the connecting ribs of the shade members are retained on the rib retaining unit.
