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： A method, an optical system and a lighting arrangement for homogenizing a bundle of light rays (110) by means of an elongated optical element (100) arranged for homogenizing light. The bundle of light rays is directed into a transversal entry face (101) of the optical element, and into at least one of the following geometrical regions: (a) a neighbourhood of the perimeter of the entry face; (b) a neighbourhood of at least a portion of a first line segment (R1) extending from the centre of the entry face to a midpoint of a vertex (123); (c) a neighbourhood of at least a portion of a second line segment (R2a) extending from the centre of the entry face to a midpoint of an edge (122).
