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 23):
The light source ( 25 ) of any one of the preceding claims, wherein at least one of the plurality of light emitting units ( 41 ) comprises a light emitting device with a light emission over an angular range that results in an angular range ( 207 ) within the light guide unit ( 34 ) of below 40\u00b0 such as below or about 30\u00b0 or 20\u00b0, e.g. about 10\u00b0, and/or\n wherein the angular range ( 207 ) is characterized by an input light central direction ( 209 ) and the input light central direction ( 209 ) is inclined with respect to the normal to the main front face ( 55 A) or main back face ( 55 B) of light guide unit ( 43 ) in particular by an angle of (the angle of TIR+half of the angular range), and/or \n wherein at least one of the plurality of light emitting units ( 41 ) comprises a white light emission spectrum, and/or wherein the plurality of light emitting units ( 41 ) comprises a variation of emission spectra.
