    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.

    摘要: A method for controlling an angular distribution of a light-beam emitted by a light-output device (102, 200) comprising a first set of light-sources (105, 211) comprising at least one light-source configured to emit light within a first angular range (221, 231, 241) and second set of light-sources (107, 210) comprising at least one light-source configured to emit light within a second angular range (222, 232, 242), wherein the first angular range is different from the second angular range. The method comprises the steps of: receiving (401) a dimmer setting (VDS) from a dimmer (101); controlling (404), if the dimmer setting is within a first predetermined range, the first set of light-sources to emit light within the first angular range; and controlling (405), if the dimmer setting is within a second predetermined range, the second set of light-sources to emit light within the second angular range. Through the method according to the invention the angular distribution of light emitted from a single light-output device may be controlled using a single switch, thereby avoiding the need for having a plurality of switches and/or new wiring which would otherwise be required.

    摘要: An illumination system has a plurality of light emitters (R, G, B) and a light-collimator (1) for collimating light emitted by the light emitters. The light-collimator is arranged around a longitudinal axis (25) of the illumination system. A light-exit window (5) of the light-collimator at a side facing away from the light-emitters is provided with a translucent cover plate (11) provided with a switchable optical element (15) based on electro wetting. The light-exit window of the light-collimator or the translucent cover plate is provided with a light-dispersing structure (7) for broadening an angular distribution of the light emitted by the illumination system. The optical element (15) being switchable in a mode of operation reducing the effect of the light-dispersing structure (7). Preferably, the effect of the light-dispersing structure is substantially counteracted when the switchable optical element operates in the mode of operation reducing the effect of the light-dispersing structure.
