ABSTRACT:
A light source having light emitting modules coupled to a flexible circuit carrier. The flexible circuit carrier includes a sheet of flexible material having electrically conducting traces connecting a circuit mounting area and a connector region. The light emitting modules are electrically connected to the circuit mounting area. In one embodiment, the light emitting modules are arranged in a linear array. The light source preferably includes a light pipe having a planar layer of transparent material, the light emitting modules being bonded to an edge of the planar layer. The light pipe is preferably attached to a printed circuit board and the connection region of the flexible circuit carrier is attached to the printed circuit board. The flexible circuit carrier can move heat from the light emitting modules to the printed circuit board as well as providing electrical connections.
