Beschreibung
Zusammenfassung:	The invention provides a lighting system (100), configured to provide lighting system light (101), the lighting system comprising:- a light source (10) configured to provide light source light (11) with light intensity in the blue spectral region;- a first luminescent material (210) configured to convert at least part of the light source light (11) into first luminescent material light (211) with light intensity in the green spectral region and having a full width half maximum (FWHM) of at least 90 nm;- a second luminescent material (220) configured to convert (i) at least part of the light source light (11), or (ii) at least part of the light source light (11) and at least part of the first luminescent material light (211) into second luminescent material light (221) with light intensity in the spectral region of 610-680 nm, wherein the second luminescent material (221) under excitation with at least part of the light source light (11), or (ii) at least part of the light source light (11) and at least part of the first luminescent material light (211) shows one or more emission lines having a full width half maximum (FWHM) at RT of 40 nm or less;- a third luminescent material configured to provide third luminescent material light upon excitation with one or more of the light source light and the first luminescent material light, wherein the third luminescent material is a broad band emitter in the orange and/or red spectral region,wherein the lighting system (100) is configured to provide at a first setting of the lighting system (100) lighting system light (101) comprising said light source light (11), said first luminescent material light (211) and said second luminescent material light (221) having a color point (x;y) with x=0.38 ±0.1 and with y=0.28±0.1.
