Abstract

Illumination arrangement (3) for lighting a reflective light modulator (4) under oblique light incidence, comprising, one after another along an optical axis (10), a light source (6) with a first axis (19) and a second axis (18), wherein the second axis (18) is arranged at right angles to the first axis (19) and a dimension of the light source (6) in the direction of the first axis (19) is preferably smaller than a dimension of the light source (6) in the direction of the second axis (18), a homogenizer (9) for coupling in the light radiation emitted by the light source (6) having an entrance face (8) and an exit face (11) and an illumination optics (12) for imaging the exit face (11) of the homogenizer (9) onto a light modulator (4) while maintaining the efficiency in such a way that homogeneous lighting of the light modulator can be achieved, wherein it is proposed that the light source (6) is arranged such that it is offset with respect to the homogenizer (9) transversely to the optical axis (10) or that an emission direction (28) of the light source (6) opposite a surface normal (29) of the entrance face (8) of the homogenizer (9) is arranged at an angle (30).
