摘要： An illumination system (8) comprises an optical waveguide (18) which is made from optically transparent components and has four end faces (10, 10′). A light source (12) whose light is coupled into the optical waveguide (18) via one of the end faces (10), is situated opposite this end face (10). The optical waveguide (18) has a light guide (30). A number of fibers (34) are attached to a surface (32) of the light guide (30). The fibers (34) have birefringent properties. A preferred method of providing the birefringent properties is to stretch fibers (34) of a suitable polymer plastic material in their longitudinal direction. The light from the light source (12) will be polarized by the fibers (34) and polarized light will be outcoupled from the optical waveguide (18) via an exit surface (16). The illumination system (8) may be used for front or back lightning of LCD panels for e.g. mobile phones, PDA's, etc.

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 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.
