LIGHT EMITTING ARRANGEMENT WITH ADAPTED OUTPUT SPECTRUM

摘要

A light-emitting arrangement (100) is disclosed, which is adapted to produce white output light enhancing the color perception of e.g. food in retail environments. The light-emitting arrangement comprises at least one blue light-emitting element (102) adapted to emit light having an emission peak in a first wavelength range of from 440 to 460 nm, and at least one deep blue light-emitting element (101) adapted to emit light having an emission peak in a second wavelength range of from 400 to 440 nm. Further, the light-emitting arrangement comprises at least one narrow band wavelength converting material (104) arranged to receive light emitted by said deep blue light-emitting element, and at least one broadband wavelength converting material (105) arranged to receive light emitted by at least one of said blue light-emitting element and said deep blue light-emitting element. A spotlight comprising such a light-emitting arrangement, and an illumination device comprising a plurality of the light-emitting arrangements, is also disclosed.
