2. Primary and Secondary Optics
Definition of Terms
Primary Optics Secondary Optics
 Lens integrated into the LED package  Optical element separate from LED
 Optimized for package
– Light extraction  Typically separated from LED by an air gap
– General beam shaping – G could also b fill d b i d
Gap ld l be filled by index
matching material to reduce Fresnel loss
– Or both
