PHOSPHOR BASED ILLUMINATION SYSTEM HAVING A SHORT PASS REFLECTOR AND METHOD OF MAKING SAME

摘要

An illumination system (1300) including a light source (1320), a light guide (1312) including an output surface (1314), emissive material (1340) positioned to receive light from the output surface (1314) of the light guide (1312), and a first interference reflector (1330) positioned between the output surface (1314) of the light guide (1312) and the emissive material (1340) is disclosed. The light source (1320) emits light having a first optical characteristic. The emissive material (1340) emits light having a second optical characteristic when illuminated with light having the first optical characteristic. The first interference reflector (1330) substantially transmits light having the first optical characteristic and substantially reflects light having the second optical characteristic.
