    摘要： The present invention relates to alight-emitting panel (1) comprising: a first panel sheet (11), the first panel sheet being optically transparent; a second panel sheet (12); and a cellular support panel (10) sandwiched between the first panel sheet and the second panel sheet. The cellular support panel comprises optically transparent cell walls (13) defining a plurality of tubular channels (14) extending from the first panel sheet towards the second panel sheet. The light-emitting panel (1) further comprises a two-dimensional light- source array (15;16;24;27) comprising a plurality of light-sources (18a-b;19a-b) each being arranged to emit light into at least one of the tubular channels of the cellular support panel. Various embodiments of the present invention provide a cost-efficient light-emitting panel with advantageous light-emission and mechanical properties.

    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 optical element for use in front of a light source for obtaining a skylight appearance, a lighting system and a luminaire are provided. The optical element comprises a light transmitting cell which comprises a light transmitting channel, a light input window, a light exit window and a wall. The light transmitting channel collimates a part of light emitted by the light source. The light exit window emits light with the skylight appearance. At least a part of the light exit window is arranged at a second side of the light transmitting channel opposite to the first side. The wall is interposed between the light input window and the part of the light exit window. The wall encloses the light transmitting channel. At least a part of the wall is reflective and/or transmissive in a predefined spectral range to obtain a blue light emission at relatively large light emission angles with respect to a normal to the part of the light exit window.
