Conversion element for generating conversion radiation, has upper side, lower side facing away from upper side and side surfaces connecting upper side and lower side, and opaque region comprises first of the side surfaces

摘要

The conversion element (10) has phosphors, and comprises a upper side (12), lower side (14) facing away from the upper side and side surfaces (16,18). The side surfaces connect the upper side and the lower side. An opaque region (20) comprises first of the side surfaces. The opaque region is extended over the entire first side surface. The opaque region is black and is formed by a layer that is formed on the conversion element. Independent claims are included for the following: (1) electromagnetic radiation generation device; (2) method for manufacturing conversion element; and (3) method for manufacturing electromagnetic radiation generation device.
