Abstract: To improve the efficiency and reliability of communication in a large and high-density wireless network 100, it is beneficial to assign a subset of the plurality of nodes 500 being router nodes 200, and the rest of the nodes being non-router nodes 300. Thus, the dense wireless network 100 splits into a sparse core mesh network and many small star networks around each router node 200. However, to commission the plurality of nodes into such a hybrid topology can be quite complex and time-consuming. This invention discloses a commissioning method that makes use of one or more neighboring relationship established among the plurality of nodes to derive a proper role for an individual node, and then to configure the individual node to operate according to the role assigned. The disclosed commissioning method may be carried out semi-automatically or automatically.

Abstract: A lighting script—for use by a lighting controller to control at least one luminaire to render illumination effects, as the video content is outputted in a space illuminated by the at least one luminaire, synchronously with the outputting of the video content—is generated as follows. Frame image data of the video content is processed to determine at least one color palette of the frame image data. A sequence of illumination effects—to be rendered during the outputting of the video content and which is modifiable by a user—is displayed to the user. The displayed sequence conveys at least one illumination color derived from the determined color palette to be rendered in at least one of the illumination effects. The generated lighting script is for rendering the modified sequence of illumination effects.

Abstract: When a light scene comprises multiple colors of light, not all white light is suitable for matching the scene. A method is provided such that a white point is determined for each color in a set of colors, to create a set of white points. A single white point is then determined based on the set of white points. This allows, for example, a user to select a light scene (e.g. a romantic scene featuring red colors) for a living room, such that lighting devices contributing to the scene emit colored light. A functional lighting device (e.g. reading light) can then emit white light, determined according to the method, to provide more functional light (e.g. light suitable for reading) that matches the scene (e.g. warm white instead of cold white).

Abstract: An illumination source comprises an array of light-emitting elements for emitting illumination to illuminate an environment. A controller is arranged to control the illumination emitted by different ones of the light-emitting elements so as to form a spatial pattern, and to vary the spatial pattern according to a spatial dimming function whereby the spatial pattern is varied so as to emit a different overall intensity level as a function of a received dimming signal. A value is determined of at least one property relating to a manner in which the illumination source is deployed (e.g. the manner in which it is installed), and the spatial dimming function is set in dependence on the value of this property.

Color values are extracted from each sub-area and the one or more lighting devices are controlled based on the extracted color values.
