Abstract: A light module for a projection device may include: at least one light source designed to emit partly polarization radiation; and a first polarization beam splitter, which is arranged in the beam path of the radiation emitted by the at least one light source, wherein the polarization beam splitter is designed to provide radiation of a first polarization at a first output and radiation of a second polarization at a second output. The light module includes a first beam cube arranged in the beam path of the radiation, a first to fourth LCD panels; a second dichroic beam splitter arranged between a first output of the first polarization beam splitter and a first input of the beam cube.

Abstract: Various embodiments may relate to a lighting device, including an excitation radiation source and a two-sided luminescent-material wheel. At least one luminescent material is provided on each of the two sides of the two-sided luminescent-material wheel, thus both on the front side and on the opposite back side. The luminescent materials on both sides are excited sequentially in time. For this purpose, at least one transmissive region is provided in the rotating luminescent-material wheel, through which transmissive region the excitation radiation can radiate, which excitation radiation can be deflected onto the luminescent material on the back side by means of an optical unit.

Abstract: A lighting device comprising a pump laser matrix (2) and a phosphor arrangement. The pump laser matrix (2) is configured to emit pump radiation (7) having a controllable pump radiation power distribution for the irradiation of the phosphor arrangement (4). The phosphor arrangement (4) comprises at least two different phosphors (R, Y, G) which can be irradiated with the pump radiation (7) and re-emit said pump radiation in a manner such that it is at least partly and in each case differently wavelength-converted. The lighting device (1) is configured to generate, with the aid of the pump laser matrix (2), a controllable distribution of the surface power density of the pump radiation on the phosphors (R, Y, G) of the phosphor arrangement (4).
