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