Abstract:
A light source ( 25 ) for emitting collimated light ( 29 ) in particular for a large area luminaire ( 21 ) comprises a light guide unit ( 43 ) comprising a plurality of light guide strips ( 91 ) configured for guiding light received at the at least one lateral coupling face ( 47 ), for example, by total internal reflection. The light guide strips comprise a plurality of localized light source regions ( 57 ) at a main front face ( 55 A) for having light pass there through, wherein the light source regions ( 57 ) are provided along the light guide strip ( 91 ) within a non-source region ( 59 ). The light source ( 25 ) further comprising a plurality of light emitting units ( 41 ) for emitting light into the light guide strips ( 91 ) through respective portions of the at least one coupling face ( 47 ), and a collimation unit ( 45 ) extending along the main front face ( 55 A) and comprising a plurality of collimating elements. Each collimating element comprises an input side and an output side, is optically associated to one of the plurality of light source regions ( 57 ), and is configured to receive light emerging from the associated light source region ( 57 ) at its input side and to emit collimated light ( 29 ) from a respective collimated light emitting region ( 61 ) formed at its output side.

Claim (Index 31):
An edge-lit large area luminaire ( 21 ) comprising\n a light source ( 25 ) as in any one of the preceding claims, and a chromatic diffusing layer ( 27 ) comprising a plurality of nanoparticles embedded in a matrix and configured to provide for a direct transmission that is larger in the red than in the blue and for a diffuse transmission that is larger in the blue than in the red, in particular positioned to be illuminated by the collimated light or to be positioned downstream of the light source regions ( 57 ) such as downstream of the input side and/or the output side of the collimation unit.
