Abstract:
A lighting system ( 100 A,  100 B) comprises a light source ( 102 ) for emitting a light beam stripe ( 220 B) with a plurality of light emitting units ( 603, 803 A,  803 B) forming an array in the longitudinal direction (X), and an optical element ( 870 ) at the exit side of the light source ( 102 ) extending across the plurality of light emitting units, and configured to enlarge the beam divergence in the transversal direction. The lighting system ( 100 A,  100 B) further comprises a reflector unit, a support structure ( 210 ), and a reflective surface ( 104 ) with an essentially linear shape in the longitudinal direction (X) and a curved shape in the longitudinal transverse direction (Y), and a chromatic diffusing layer ( 108 ) comprising a plurality of nanoparticles embedded in a matrix, wherein the chromatic diffusing layer ( 108 ) is positioned such that at least a portion of the reflected light beam ( 220 A) passes through the chromatic diffusing layer ( 108 ), thereby generating diffuse light by scattering more efficiently the short-wavelengths components of the light in the visible spectral range than the long-wavelength components of the light in the visible spectral range.

Claim (Index 19):
The lighting system ( 100 A,  100 B) of anyone of the preceding claims, wherein a difference in the refractive index of the nanoparticles with respect to the refractive index of the matrix, a size distribution of the nanoparticles, and a number of nanoparticles per unit surface area are selected to provide for the specular reflectance to be larger in the red than in the blue and for the diffuse reflectance to be larger in the blue than in the red, and wherein in particular the differences in the specular reflectance and the diffuse reflectance are given as average values with respect to a blue portion and a red portion in the visible light spectrum, e.g. within a blue portion in the spectral range from 450 nm to 500 nm and a red portion in the spectral range from 620 nm to 670 nm and/or\n wherein the nanoparticles and the matrix are essentially non-absorbing.
