Fluorescent assembly with fluorescent element and optical system, light source unit with fluorescent assembly, method for converting light using fluorescent assembly, and use of fluorescent assembly or light source unit

摘要

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.
