MODULE EXCHANGING TYPE LIGHTING APPARATUS

摘要

PURPOSE: A module exchanging type lighting apparatus is provided to obtain necessary light distribution by combining a plurality of light source modules and arranging them. CONSTITUTION: In a module exchanging type lighting apparatus, a light source module(20) is coupled to a frame(10) and is detachable. The light source modules are exchanged between the reciprocity. At least two light source modules is selected from a first light source module(20a) and a second light source module(20b). The first light source module radiates light in wide radiation angle. The second light source module radiates light in narrow radiation angle.
