<p>A device with at least one light source, comprising several individual light sources (3, 3') and an optical arrangement. At least two individual light sources (3, 3') comprise a light-emitting surface with different, long axes perpendicular to each other. At least two individual light sources (3, 3') form at least one individual light source grouping (4, 4'), which is arrange d coaxially to the optical axis (5) of an astigmatic optical element (7). Said astigmatic optical element (7) is impinged upon by the emitted bundles (2) from the individual light sources. One axis of the emission surface of an individual light source (3) lies on the meridional plane of the astigmatic optical element (7). Said plane is defined through the mid-point of the emission surface. The other axis of the emission surface lies on the corresponding sagittal plane. The astigmatic optical element (7) has differe nt imaging characteristics on the respective meridional and saggital planes for each light source (3), whereby each emitted bundle (2), in the light path to the astigmatic optical element (7), comprises a cross-sectional area with essentially equally long axes, on at least one compensation plane (13) which is perpendicular to the optical axis of the astigmatic optical element (7). All emitted bundles (2) areguided by bundle-guiding components (7, 11, 12, 7') on to a working plane (13), which is either formed by the compensation plane, or an optical plane which is common to all beams. A working beam of high intensity is thus generated by superimposition of the emitted bundles.< /SDOAB></p> |
