Abstract: A lighting system comprising a plurality of controllable light emitting elements is disclosed. The lighting system further comprising a spreading optical element arranged in front of the plurality of light emitting elements to shape the light emitted from the lighting elements, and a controller for varying a light emission angle range of light emitted from the spreading optical element by controlling each of the plurality of controllable light emitting elements. This allows the light emitted from the spreading optical element to be varied without varying any physical parts of the lighting system, because the controller now controls each of the light emitting elements, by e.g. dimming one or more of the light emitting elements or by switching one or more of the light emitting elements off.

Abstract: A lighting system comprising a plurality of controllable light emitting elements 3 is disclosed. The lighting system further comprising a spreading optical element 5 arranged in front of the plurality of light emitting elements to shape the light emitted from the lighting elements, and a controller 7 for varying a light emission angle range of light emitted from the spreading optical element 5 by controlling each of the plurality of controllable light emitting elements. This allows the light emitted from the spreading optical element to be varied without varying any physical parts of the lighting system, because the controller now controls each of the light emitting elements, by e.g. dimming one or more of the light emitting elements or by switching one or more of the light emitting elements off.

Abstract: It is disclosed a method for operating a lighting system, which lighting system comprises a plurality of lighting modules, each of which comprises at least one communication unit, via which the respective lighting module is adapted to communicate with at least one neighboring lighting module. A control device may be adapted to communicate control signals to at least one of the lighting modules and each of the lighting modules may be adapted to further communicate control signals communicated to the lighting module to a neighboring lighting module.

Abstract: The invention relates to a modular lighting unit (1) comprising a front side (2), a rear side (3) opposite to the front side (2), at least three edge sides (4a, 4b) surrounding the front side (2), light elements (5) disposed on at least the front side (2), and a magnetic fastening arrangement for attachment with a corresponding magnetic fastening arrangement on a neighboring lighting unit (1). The magnetic fastening arrangement comprises sets of magnets (7a, 7b) of different polarities. Since a pair of magnets may be connected to each other only if the polarities are opposite, the magnets of the modular lighting unit (1) are positioned and the polarities of the magnets (7a, 7b) are arranged, such that two adjacent edge sides (4a, 4b) of two similar neighboring lighting units (1) may be attached to each other only if the modular lighting unit (1) is correctly rotated, resulting in that correct alignment of the lighting units (1) is ensured.

Abstract: It is disclosed a method for associating pixels of visual content displayed on a display unit with pixels of lighting modules, where each lighting module comprises a plurality of pixels, and the lighting modules are adapted to be comprised in a lighting system comprising a plurality of lighting modules and a control device, wherein the control device is adapted to communicate control signals to the lighting modules. Each of the lighting modules may communicate control signals with neighboring lighting modules, and to any of the pixels of the lighting module. Pixels of the visual content may be selected by means of a visual representation of pixels associated with the lighting modules displayed onto the display unit, wherein each pixel of the visual representation corresponds to a pixel of the lighting modules.
