Abstract
A mounting block of a lighting fixture includes a plurality of tilting screw holes inclinedly formed in the block for detachably mounting a plurality of supporting leg members in a bottom portion of the block, and a central hole vertically formed through the block for detachably securing a central post of a lamp socket or a shade in the central hole, whereby upon positioning of the mounting block on a lower position of a lighting fixture, the mounting block will serve as a supporting base of the lighting fixture; and upon positioning of the mounting block on a middle portion of a lighting fixture, the mounting block will serve as a lamp holder for directly securing a lamp socket and a shade on the block; and upon positioning of the mounting block on an apex of a lighting fixture, a fantastic pyramid structure of lighting fixture will be formed by suspending the shade and lamp socket on the supporting leg members protruding inclinedly downwardly from the mounting block.
