Multi LED light engine basic optical Multi LED light engine basic optical conceptconcept
LED-emission: e.g. NA 1LED-pitch: e. g. 10 mm
Output-emission: NA 0.5Output-pitch: 2 mm, 1.5 mm
Benefit of using fiberoptics:Pitch transformationProvide workable aperture and shape for emitting surface
NA Pitch
NA 1 NA 0.5

Numerical aperture transformation by Numerical aperture transformation by a tapera taper
Small End NAsame as base material
Large End NAcalculated as the inverse of the magnification ratio times the based NAthe large end NA will always be smaller than that of the small end NAexample 2:1 taper NAeff = (1/2) x (1.0)NAeff = 0.5 (Large End)
NA = 1.0 (Small End)
2:1
NA = 0.5 (Large End)

What are our main challenges ?What are our main challenges ?LED to fiber coupling challenges today
We need higher light density We don‘t like lambertian emitters, we like spot emitter (± 30°)
without bulky opticsHigh efficient cost effective opticsWe have to use UV and high temperature ( < 150°C) stable
materials
Schott LED product requirements
High uniformity from LED to LEDHigh CRILess heat and/or very well designed heat managementCustomized cost effective optics on chipSmaller form factor
