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 40):
A light source ( 25 ) for emitting collimated light ( 29 ) in particular for an edge-lit large area luminaire ( 21 ), the light source ( 25 ) comprising:\n a light guide unit ( 43 ) having a main front face ( 55 A), a main back face ( 55 B), and at least one lateral coupling face ( 47 ) connecting the main front face ( 55 A) and the main back face ( 55 B) in a thickness direction (d T ), wherein\n the light guide unit ( 43 ) is configured for guiding light received at the at least one lateral coupling face ( 47 ) by total internal reflection between the main front face ( 55 A) and the main back face ( 55 B), and \n the main front face ( 55 A) comprises a plurality of localized light source regions ( 57 ) for having light pass there through, and \n a plurality of light emitting units ( 41 ) for emitting light into the light guide unit ( 43 ) through the at least one coupling face ( 47 ); a collimation unit ( 45 ) extending along the main front face ( 55 A) and comprising a plurality of collimating elements, wherein 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; and a light emitting face ( 63 ) formed by the collimated light emitting regions ( 61 ), wherein the light emitting units are configured to emit primary light with a spectral distribution that compensates for spectral losses accumulated by the primary light while propagating within the light guide unit ( 43 ), and/or wherein the light emitting units comprise subgroups ( 51 A,  51 B) for generating counter-propagating light within the light guide unit ( 43 ) to compensate for losses accumulated by the primary light while propagating within the light guide unit ( 43 ) and to provide for comparable light extraction at comparable light source regions such that the luminance per area section of the light emitting face is essentially homogeneous.
