Abstract

A single side emitting, multi-segment linear light source is disclosed. Each segment of the light source has an LED, a light guide with light extraction features, and a bent reflector sheet. All of this is mounted on a PCB that is bent in a plurality of places. The PCB provides mechanical support, electrical contacts and conducts heat generated by the LED away. Electrical connections are provided across the bend in the PCB using novel means.
