Abstract: A projection apparatus includes a light source for emitting light with an initial spectral distribution, an optical element, and a projection surface. The optical element is arranged in a beam path of light emitted from the light source between the light source and the projection surface. The optical element includes a number of pixels. The pixels of the optical element are each configured to convert light with the initial spectral distribution into light with a predetermined final spectral distribution different from the initial spectral distribution.
