Optoelectronic Arrangement having a Radiation Conversion Element and Method for Producing a Radiation Conversion Element

An optoelectronic arrangement comprising:

• a semiconductor chip comprising an active region configured to generate radiation;
• a radiation conversion element arranged downstream of the semiconductor chip in an emission direction,
• wherein the radiation conversion element comprises a plurality of conversion bodies each having an axis of symmetry,
• wherein a spatial orientation of the axes of symmetry comprises a preferred direction, and
• wherein a radiation emitted by the conversion bodies comprises a preferred polarization;
• and
• a reflective polarization element arranged downstream of the radiation conversion element in the emission direction,
• wherein the reflective polarization element largely allows the radiation with the preferred polarization to pass, and largely reflects radiation polarized perpendicular to the preferred polarization.

A method for producing a radiation conversion element, the method comprising:

• providing a basic material in liquid form, which is provided with conversion bodies each having an axis of symmetry;
• filling the basic material into a mold;
• at least partially orienting the axes of symmetry of the conversion bodies along a preferred direction;
• and
• curing the basic material.
