LIGHT-EMITTING ARRANGEMENT WITH ADAPTED OUTPUT SPECTRUM Russian patent published in 2018 - IPC F21K99/00 F21V9/08 H01L33/50 C09K11/08 F21Y101/00 F21Y103/00 F21W131/405 

FIELD: lighting.

SUBSTANCE: invention relates to lighting engineering. Light-emitting arrangement (100) is disclosed, which is adapted to produce white output light enhancing the colour perception of, for example, food in retail environments. 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. Spotlight comprising such a light-emitting arrangement, and an illumination device comprising a plurality of the light-emitting arrangements, is also disclosed.

EFFECT: technical result is an increase in transmission efficiency and saturation of red or green colour.
