Abstract
A luminescence conversion element for wavelength conversion of primary electromagnetic radiation into secondary electromagnetic radiation includes first luminescent material particles that, when excited by the primary electromagnetic radiation, emit a first electromagnetic radiation, a peak wavelength of which is at least 515 nm to at most 550 nm of a green region of the electromagnetic spectrum; second luminescent material particles that, when excited by the primary electromagnetic radiation, emit a second electromagnetic radiation, a peak wavelength of which is at least 595 nm to at most 612 nm of a yellow-red region of the electromagnetic spectrum; and third luminescent material particles that, when excited by the primary electromagnetic radiation, emit a third electromagnetic radiation, a peak wavelength of which is at least 625 nm to at most 660 nm of a red region of the electromagnetic spectrum.
