Abstract: The invention relates to a lighting apparatus (1). A first light device (52) comprises a first light source (2) for generating a first light beam (3) and a light emanating element (6) from which the first light beam (3) emanates. A second light device (53) with a second light source (4) generates a second light beam (5) being directed to the light emanating element (6) of the first light device (52), wherein the light emanating element (6) is adapted to redirect the second light beam (5) such that the redirected second light beam (7) emanates from the light emanating element (6). Since the first light beam (5) and the redirected second light beam (7) emanate from the light emanating element (6), both light beams appear to originate from the same location. The probability of generating selective shadowing effects can therefore be reduced, in particular, selective shadowing effects can be eliminated.

Abstract: 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.

Abstract: The invention relates to a primary light converter (1) for converting primary light (3) into secondary light (4). An electrical light conversion unit (2) converts at least a part of the primary light (3) into the secondary light (4), and an energy converter (5) converts at least a part of the primary light (3) into electrical energy, wherein the electrical light conversion unit (2) is adapted to be driven by the electrical energy from the energy converter (5). The invention relates further to a lighting apparatus comprising one or several of the primary light converters. It is not necessary to electrically connect the one or several primary light converters via a wire to an external power supply. This reduces the space required for the primary light converter and the lighting apparatus and increases the variability of possible arrangements of the one or several primary light converters and lighting systems comprising such primary light converters.

Abstract: The invention relates to a lighting apparatus (1) for generating a light pattern. A light source (4) generates a light beam (5) for being directed onto a liquid crystal cell (2). The liquid crystal cell (2) comprises a periodic structure (3). If voltage is applied to the liquid crystal cell (2) by a voltage source (8), a period phase pattern is generated. The liquid crystal cell (2) and the light source (4) are adapted such that multiple separate light beams (6) are generated in different directions by diffraction at the generated periodic phase pattern, wherein the multiple separate light beams (6) form the light pattern (7). Since the light pattern is generated by diffraction at the periodic phase pattern, which is modifiable by applying voltage, different light patterns can be generated, in particular, for decorative purposes, in a technically relatively simple way.
