Claim Text:
1. A light-emitting arrangement adapted to produce output light, comprising: at least one blue light-emitting element adapted to emit light having an emission peak in a first wavelength range of from 440 to 460 nm; at least one deep blue light-emitting element adapted to emit light having an emission peak in a second wavelength range of from 400 to 440 nm; at least one narrow band wavelength converting material arranged to receive light emitted by said deep blue light-emitting element, wherein the narrow band wavelength converting material is adapted to emit light with a full width half maximum (FWHM) of less than 50 nm; and at least one broadband wavelength converting material arranged to receive light emitted by at least one of said blue light-emitting element and said deep blue light-emitting element, wherein the broadband wavelength converting material is adapted to emit light with a full width half maximum (FWHM) of 50 nm or more.
