Abstract

A LED light source includes a longitudinally extending first light guide, a housing, and a cartridge. The first light guide has a longitudinally extending light emitting face. The light emitting face has a first end face and a longitudinally spaced apart second end face. The housing has a first side proximate the first end face of the first light guide. The cartridge is mountable to the first side of the housing and has at least one LED on a first face of the cartridge. The first face extends generally transverse to the first light guide when the cartridge has been mounted to the housing. When the cartridge is mounted to the first side of the housing, the first face of the cartridge is adjacent the first end face. A LED light bulb is also disclosed.
