LIGHT SOURCE UNIT WITH PHOSPHOR ELEMENT

摘要

The invention relates to a light source unit, which comprises a pump light source (1) for an emission of pump light (2), a phosphor element (3) for a conversion of the pump light (2), and an optical system (6) for transmitting the converted light (4) for a further use, for example to an exit aperture (5) serving as an imager of a projection system. Therein, the pump light (2) is coupled into and transmitted by the optical system (6) to the phosphor element (3).
