LINEAR LIGHT SOURCE WITH FLEXIBLE PRINTED CIRCUIT

摘要

A linear light source assembly including a light guide bar with patterned light emitting surface, a reflective holder, a light emitting diode (LED) light source module, and a flexible printed circuit (FPC) is disclosed. The light guide bar is an elongated polygonal transparent material with a light-scattering patterned light emitting surface where the light exits. The FPC is a flexible plastic substrate with a plurality of conductive traces and a plurality of FPC holes in the flexible plastic substrate. The light guide bar is disposed in the holder. The LED light source module is attached to the FPC. Holder posts are inserted into the FPC holes to align and hold the FPC with LED light source module to the holder and position the LED light source module adjacent to a light-receiving end of the light guide bar.
