Abstract

A modular LED unit (10) having a number of LED modules (12) separately mounted on individual interconnected preferably-extruded heat sinks (14), each heat sink having: a base (20) configured to engage and hold an LED module (12) in place and, in preferred forms, to facilitate the ganging of heat-sink/LED modules; and a plurality of fins, including inner-fins (30) and side-fins (40,50), projecting from the opposite surface (24) of the base (20) and extending therealong, the side-fins (40,50) having interlocking features to facilitate the ganging of heat-sink/module units together and, in preferred forms, to facilitate interconnection of the modular LED unit to other portions of a lighting fixture.
