Various embodiments propose an illumination apparatus having a laser apparatus and a phosphor wheel, wherein the phosphor wheel has, in addition to at least one phosphor region for phosphor conversion, at least one transmission region for colored light having a second, greater dominance wavelength from a light source. The beam paths from light source and laser apparatus are e.g. arranged collinearly, wherein the phosphor wheel rotates into the common optical axis of the laser apparatus and light source. By adding colored light having a greater dominance wavelength, the dominance wavelength of a colored light channel that is required for projection applications can also be obtained with colored light converted using efficient phosphor having a dominance wavelength that is too small.
