Embodiment Construction
[0031] figure 1 A schematic diagram of a projection system as used, for example, in a projection device, namely a video projector (Beamer) or in a rear projection device, also known as a projection television (RPTV), is shown.
[0032] A lighting device 1 is provided which generates mixed light from light having different wavelengths. Since the generated light is used for illumination, at least a part is in the visible range. However, it is not necessary that the entire light of the so-called mixed light is in the visible range. The lighting device 1 has three mixed light emitters 2 that radiate mixed light, respectively. The resulting mixed light is deflected via optical element 3 onto light modulator 4 . The light modulator 4 is, for example, a liquid crystal matrix, also called an LC matrix. The predetermined area of the light modulator 4 is uniformly illuminated by the optical element 3 with the light emitted by the lighting device 1 .
