Abstract

A method of manufacturing a plurality of conversion elements includes providing a first conversion layer on an auxiliary carrier, the first conversion layer converting electromagnetic radiation of a first wavelength range into electromagnetic radiation of a second wavelength range, applying a second conversion layer on the first conversion layer, the second conversion layer converting electromagnetic radiation of the first wavelength range into electromagnetic radiation of a third wavelength range, and separating the generated layer stack such that a plurality of conversion elements are generated, wherein each conversion element includes at least one first converting region having material of the first conversion layer, each conversion element includes at least one second converting region having material of the second conversion layer, and the converting regions are arranged laterally side by side.
