ABSTRACT:
Lamp apparatus consisting of assembled polyhedric modules, each module comprising a shaped, hollow polyhedron and a light mounted in the polyhedron. Each polyhedron has sides with circular ribs extending therefrom. The assembly of two consecutive modules is achieved by nesting the circular complementary ribs provided on the sides to be assembled of those two modules. The complementary parts are coaxial and thereby permit each module to rotate independently about the axis.
