Abstract

This invention relates to a phosphor assembly with a phosphor element for converting pump light into converted light, and an optical system for transmitting converted light and/or pump light. Therein, a liquid immersion material is provided in a gap between the phosphor element and the optical system, wherein an excess of immersion material enables a continuous exchange of the material in the gap and thus provides a cooling.
