Abstract
An illumination arrangement for a color measurement device includes a linear arrangement of light emitting diode chips () packed tightly along a narrowly defined path. A plurality of light emitting diode chips within at least one region of the path emit light of substantially the same color and are directly covered together with a resin in which a converter material is included for the conversion of the light emitted by the light emitting diode chips of the plurality thereof into at least one other wavelength range. An illumination light with cosine characteristic is emitted from a surface of the resin. UV light emitting regions and non-UV light emitting regions as well as regions including color filters and/or polarization filters may be provided. The illumination arrangement may include white emitting regions and narrow band emitting regions constructed especially for color density measurement.
