    摘要: The invention relates to a method for manufacturing a diffusive reflector (450) for a reflective or transflective Liquid Crystal Display (400). The reflector comprises a surface (452) that is structured by means of a photo-embossing process. Herein, a layer (100) of a mixture is provided including a photo-diffusible monomer (102), which may be transported through the layer under the influence of selectively applied irradiation. A layer relief is thus formed, which is preferably developed further at an elevated temperature. The layer is fixed and stabilized by means of a cross-linking step, preferably including thermally induced and/or photo-induced polymerization. In a final step, the polymer relieved surface thus formed is provided with a reflective material (154).

    摘要: 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.

    摘要: The invention relates to an illumination system (50), a beam-control element and a light source (30). The illumination system comprises the light source for emitting a light beam and a beam-control element for controlling the shape and/or direction of the light beam. The beam-control element comprises a resilient layer (2a) and a further layer (4a) being arranged substantially parallel to each other, the resilient layer comprising a relief (21) on a surface of the resilient layer arranged substantially parallel to the further layer, or the further layer comprising the relief on a surface of the further layer facing the resilient layer. The illumination system further comprises moving means (52) for moving the resilient layer and the further layer with respect to each other for reducing the relief by applying a pressure between the resilient layer and the further layer. The relief controls the shape and/or direction of the light-beam. When the relief is reduced by applying pressure, the light beam is substantially unaltered by the beam-control element.

    摘要: The present invention relates to a device (200) for electrically controlling shaping of a light beam. The device comprises primary optics (202) that is arranged to shape the light beam originating from a light source (201). The device further comprises an electrically controllable optical element (203) arranged to change the direction of the light falling onto it, when the element is in a light-redirecting mode. The optical element can be an electrically controllable scattering element e.g. created by using a PDLC material or an LC gel. The degree of light redirection of the optical element is controlled by applying an electric field to the LC material. Finally, the device comprises secondary optics (204) arranged to shape the scattered, diffracted or refracted light beam from the optical element.
