Abstract

The device has several LEDs (2), and a lens array (3), which comprises several lenses (4) for collimating and/or focusing of the radiation emitted by the LEDs. Another lens array (5) having lenses (6) follows the array (3) in an emitted direction of the LEDs. The lens (4) exhibits an optical axis, which is arranged opposite to an optical axis of the lens (6). A screen arrangement (12) is arranged between the two lens arrays.
