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
