Problems solved by technology

However, in the presence of many luminaires in the lighting system, it can be difficult to achieve the desired light scene, especially when the desired light scene requires deep dimming levels (i.e. low intensity light scenes)

Embodiment Construction

[0035] It should be understood that the drawings are only schematic and not drawn to scale. It should also be understood that the same reference numbers are used throughout the drawings to indicate the same or similar parts.

[0036] In the context of this application, where reference is made to the dimming level capability of a lighting device, this is to be understood as the minimum amount of luminous output (eg in lumens) that the lighting device is capable of producing. This can be expressed as an absolute value or as a fraction of the maximum amount of luminous output that the lighting device is capable of producing. For example, a lighting fixture with 8 dimming levels may produce 1 / 8 of its maximum luminous output at its highest dimming level (ie, the level at which the amount of luminous output produced by the lighting fixture is reduced the most). As will be understood from the foregoing, a high dimming level is equivalent to a high reduction in the maximum luminous ...

Abstract

A controller (10) for a lighting system (1) including a plurality of lighting devices (20) having different dim level capabilities is disclosed. The controller is configured to determine the dim levelcapability for each of said lighting devices, determine positions of said lighting devices, and create a light scene having a defined dim level with the lighting system by controlling a subset of said lighting devices selected from the plurality of lighting devices based on the determined dim level capabilities and respective positions of the lighting devices relative to a target location. Also disclosed is a lighting system including such a controller, a method of controlling such a lighting system and a computer program product for implementing such a method.

Description

technical field [0001] The invention relates to a controller for a lighting system comprising a plurality of lighting devices. [0002] The invention also relates to a lighting system comprising such a controller. [0003] The invention also relates to a method of controlling a lighting system comprising a plurality of lighting devices. [0004] The invention also relates to a computer program product for implementing such a method. Background technique [0005] Currently, there are connected lighting systems in which a plurality of lighting fixtures are connected to a central controller arranged to control the lighting fixtures. Such a connected lighting system is attractive because the controller can use the lighting fixtures to generate different light scenes, such as static or dynamic light scenes, for example to create a certain Atmosphere or light effect. [0006] Certain light scenes may involve the controller applying dimming instructions to the lighting fixtures...
