The invention relates to at least one light emitter which is arranged to illuminate at least one illumination face via a microshutter arrangement, said microshutter arrangement comprising at least one microshutter, each microshutter comprising a transillumination hole and an electrically activatable diaphragm device associated with it, at least one of the light emitters being arranged to illuminate at least two microshutters via a first lens arrangement, said lens arrangement comprising at least one microlens arranged with respect to each microshutter so that the light emitted by the light emitter or emitters is focused in the individual microshutters. According to the invention it is possible to achieve an illumination over very large areas with an unprecedentedly high and homogeneous illumination intensity on an illumination face.
