A plurality of glass clamps equal in number to the plurality of holes in the lower fixing frame include two troughs on opposite sides thereof and two screws on opposite ends thereof. Screws at the lower ends of the clamps are inserted into respective holes of the lower fixing frame. A plurality of glass panels have side edges which extend into the troughs of the glass clamps so that the clamps and the panels are distributed around the lower fixing frame. The upper fixing frame with the plurality of holes is engaged onto the upper screws of the clamps. A U-shaped connecting frame having a lower set of holes is also fitted onto the upper screws of the clamps. A similarly constructed upper half of the lamp set includes a second lower fixing frame and a cover frame having clamps with troughs and screws thereon and including glass panels with side edges engaged in the trough.
