Zusammenfassung:A method for fabricating a frusto-conical micro-lightguide for collimation of light emitted from micro-LEDs. The method comprises depositing a layer of UV-curable material onto a substrate. A first part of the layer is selectively cured using UV light having a conical irradiation profile to define a shape of the frusto-conical micro-lightguide. The UV-curable material is developed to remove one of the first part of the layer and a second part of the layer, wherein the second part of the layer is uncured.
