Lighting system with enhanced color gamut

Abstract

The invention provides a light generating system () comprising (i) one or more light generating devices () and (ii) two or more luminescent materials (), wherein: (A) the one or more light generating devices () are configured to generate device light (); wherein the one or more light generating devices () comprise a first light generating device (); (B) the first light generating device () is configured to generate first device light () having a peak wavelength selected from the range of 440-460 nm; (C) the two or more luminescent materials are configured to generate luminescent material light (); wherein the two or more luminescent materials () comprises a first luminescent material () and a second luminescent material (); (D) the first luminescent material () is configured to convert at least part of the first device light () into first luminescent material light () having a peak wavelength selected from the range of 495-580 nm, and a full width half maximum selected from the range of 25-120 nm; (E) the second luminescent material () is configured to convert at least part of the first device light () and/or part of the first luminescent material light () into second luminescent material light () having a peak wavelength selected from the range of 600-680 nm, wherein the second luminescent material () at least comprises a luminescent material configured to provide luminescent material light in said wavelength range having a full width half maximum selected from the range of 50-140 nm; (F) the light generating system () is configured to generate white system light () comprising at least part of the device light () and at least part of the luminescent material light ().
