Abstract
A device for providing electromagnetic radiation may include a radiation arrangement for generating excitation radiation, and at least one conversion element for generating conversion radiation, which includes condensed metal phosphate and phosphors embedded in the condensed metal phosphate, and is arranged at a distance from the radiation arrangement in a beam path of the excitation radiation. The conversion element includes a silicatic matrix and alkali metal phosphate.
Claims16
A device for providing electromagnetic radiation, comprising:
- a radiation arrangement for generating excitation radiation, and
- at least one conversion element for generating conversion radiation, which comprises condensed metal phosphate and phosphors embedded in the condensed metal phosphate, and is arranged at a distance from the radiation arrangement in a beam path of the excitation radiation,
- wherein the conversion element comprises a silicatic matrix and alkali metal phosphate.
(canceled)
The device as claimed in one of the preceding claims, wherein the radiation arrangement comprises at least one radiation source, which generates the excitation radiation with a high luminous density.
