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)


FiberopticFiberoptic LED array coupling componentsLED array coupling componentsFacilitates the focusing of multiple LED outputs

Provides thermal management of LED components

Customized designs depending on desired output

Lead free materials

Materials will not degrade with UV exposure

High temperature resistance

Multiple numerical apertures designs are available (high index)

LED / Fiber Optic elements can easily be combined with integrating tunnels and conventional optics


Multi LED light engineMulti LED light engine

Potential hermetic sealing

LED IlluminationArray on input

Formed Clad Rod aligned and coupled to each LED

Output Illumination based on Numerical Aperture

Coupling taper, for high coupling efficiency


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
