Method of producing an optoelectronic lighting device and optoelectronic lighting device
Abstract:
A method of producing an optoelectronic lighting device includes forming a volume emitter such that it is at least partly transmissive to generated electromagnetic radiation, forming a concavely formed, optically transparent frame element including a curable, flowable material including phosphor particles at a side region of the volume emitter, wherein forming a conversion layer that converts the electromagnetic radiation into a second wavelength range is carried out by a sedimentation process of phosphor particles, and the conversion layer is formed within an optically transparent frame element in a manner adjoining an optically active region, forming a reflection element on the optically transparent frame element, and forming a conversion element that converts the electromagnetic radiation into a second wavelength range, wherein the conversion element is formed in a manner overlapping at least a second surface of the volume emitter and frame element.
