LIGHT SOURCE, LUMINAIRE AND SURGICAL ILLUMINATION UNIT

摘要

The Invention provides a light source, a luminaire and a surgical illumination unit in which two narrow-band light emitters both emit light in a narrow spectral peak having a full-width-half-maximum equal to or smaller than 40 nanometers. Both of the narrow-band light emitters have a different central emission wavelength within a blue color-range, within a green color range or within a red color-range. At least one of the two narrow-band light emitters comprises a luminescent material for generating the narrow spectral peak. The light source is further configured such that a distance between the narrow spectral peaks of the two narrow-band light emitters prevents overlap of the narrow spectral peaks. Due to the individual narrow spectral peaks, a color contrast within one of the color-ranges is significantly enhanced.
