PAT E NT K RAV
1. Fremgangsmåde til hærdning af en coating på en glasfiber, omfattende: at lede en glasfiber med en ufuldstændigt hærdet coating ved en linjehastighed Vf gennem et hulrum og langs en hærdningsakse, der er defineret af hulrummet; at udsende UV-stråling fra et første UVLED-array ind i hulrummet for at fremme hærdningen af coatingen, hvor det første UVLED-array omfatter en flerhed af UVLED-kilder, der hver især udsender et oscillerende output xn(t) af UV-stråling med en maksimal outputintensitet xn(t)max og en minimal outputintensitet xn(t)min; hvor det første UVLED-array definerer en normaliseret sum xtotal(t,Vf):
k = antallet af UVLED-kilder i det første UVLED-array, dn = afstand langs hærdningsaksen fra en første UVLED-kilde til en n’te UVLED- kilde; og hvor xtotai(t,Vf) ved en given linjehastighed ved koordination af fase, varighed og/eller arbejdscyklus af de respektive UVLED-kildeoutputs har en i det væsentlige konstant værdi.
2. Fremgangsmåde ifølge krav 1, hvor den maksimale outputintensitet xn(t)max af hver UVLED-kilde i det første UVLED-array er i det væsentlige den samme.
3. Fremgangsmåde ifølge et hvilket som helst af kravene 1 -2, der omfatter trinet at justere fasen af outputtet fra mindst en UVLED-kilde som reaktion på en
ændring i glasfiberens linjehastighed Vf, således at xtotai(t,Vf) har en i det væsentlige konstant værdi for en given linjehastighed.
4. Fremgangsmåde ifølge et hvilket som helst af kravene 1 -3, der omfatter trinet at øge outputintensiteten af UVLED-kilderne som reaktion på forøgelse af glasfiberens linjehastighed Vf.
5. Fremgangsmåde ifølge et hvilket som helst af kravene 1 -4, der omfatter trinet at reducere outputintensiteten af UVLED-kilderne som reaktion på en aftagen i glasfiberens linjehastighed Vf.
6. Fremgangsmåde ifølge et hvilket som helst af kravene 1 -5, der omfatter trinet at drive en UVLED-kilde i det første UVLED-array ved en strøm, der er større end UVLED-kildens maksimale mærkestrøm, hvor UVLED-kilden har en maksimal outputintensitet xn(t)max, der er større, end det kunne opnås, hvis UVLED-kilden blev drevet ved dens maksimale mærkestrøm.
7. Fremgangsmåde ifølge et hvilket som helst af kravene 1-6, der omfatter: at drive en flerhed af UVLED-kilder, der definerer et andet UVLED-array, hvor hver UVLED-kilde i det andet UVLED-array drives ved en strøm, der er større end dens maksimale mærkestrøm, hvor hver UVLED-kilde i det andet UVLED-array har et oscillerende output yn(t) af UV-stråling med en maksimal outputintensitet yn(t)maxog en minimal outputintensitet yn(t)min, hvor den maksimale outputintensitet yn(t)max af hver UVLED-kilde er større, end det kunne opnås, hvis hver af UVLED-kilderne blev drevet ved dens maksimale mærkestrøm, og hvor den maksimale outputintensitet yn(t)max af mindst en UVLED-kilde i det andet UVLED-array er forskellig fra den maksimale outputintensitet xn(t)max af mindst en UVLED-kilde i det første UVLED-array; og at lede UV-stråling fra det andet UVLED-array for at fremme hærdningen af coatingen.
