Embodiment Construction

[0045] figure 1 A side view of the wavelength conversion body 1 according to the first embodiment is shown in a sectional view. The wavelength conversion body 1 is used to generate wavelength converted light from the primary light P incident to the wavelength conversion body 1. The primary light P can be, for example, laser light generated by a laser or light with a narrow bandwidth generated by a light emitting diode. However, the type of light source that generates the primary light P is not limited in principle and may also include, for example, a light source with wide bandwidth radiation with or without a filter arranged downstream, or a wavelength emission with linear emission or broadened pressure. Range of discharge lamps. It is also possible to use a particle beam radiator (e.g., electron beam or ion beam).

[0046] The wavelength conversion body 1 has a light guide 2 that is transmissive to primary light P, in particular transparent. The light guide 2 here has the sh...

Abstract

The invention relates to a wavelength converting body (1) for generating wavelength-converted light (S) from primary light (P) incident on the wavelength converting body (1), said wavelength converting body having a specificity for the primary light ( P) and wavelength-converted light (S) light-transmissive light conductor (2) and a luminescent material body (6) with at least one luminescent material, wherein the light conductor (2) is combined with at least one luminescent material body (6 ) monolithically connected. The invention also relates to a method for producing a wavelength converting body (1; 11).

Description

Technical field [0001] The present invention relates to a wavelength conversion body for generating wavelength-converted light from primary light incident on the wavelength conversion body. The invention also relates to a method for manufacturing a wavelength conversion body. Background technique [0002] In the application of LARP ("Laser Activated Remote Phosphor"), the luminescent material ("Phosphor" in English) is irradiated by means of a laser with primary light. The luminescent material converts at least a portion of the primary light into wavelength-converted light, typically into light with a larger wavelength ("down-conversion"). The energy difference between the primary light and the wavelength converted light is output as "Stokes heat", which causes heating of the luminescent material. The heating of the luminescent material can in turn cause a shift in the wavelength or peak wavelength of the wavelength-converted light ("Stokes shift"), resulting in a decrease in q...
