摘要

The invention relates to an illumination apparatus (1) for illuminating an object (2) with an illumination pattern, in particular for decorative lighting. The apparatus comprises a first light device (3) for generating a first light beam (4) and an optical medium (5) comprising a diffractive optical element (6), wherein the diffractive optical element (6) is adapted to generate a first illumination pattern (11) and wherein the first light device (3) and the optical medium (5) are arranged such that the first light beam (4) is directed to the diffractive optical element (6) for generating the first illumination pattern (11) on the object (2). A diffractive optical element can be written onto an optical medium such that the diffractive optical element has sub-micron features, thereby allowing to increase the spatial resolution of the illumination on the object in comparison to using a LC-SLM or a LCoS for illuminating an object.
