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 39):
The light source ( 25 ) of  claim 38 , wherein the input light central direction ( 209 ) is inclined with respect to the light propagation direction of light guide unit ( 43 ) in particular by an angle that allows the beam to be completely guided by TIR, preferably with the most inclined rays (inclination with respect to the central direction) propagating close to the critical angle (limit for the TIR condition) such as an angle with respect to the normal of about the sum of the angle for total internal reflection and half of the angular range ( 207 ).
