Patent attributes
The invention relates to the control of networked lighting systems, particularly large scale networked lighting systems, and more specifically to an efficient transmission of messages to control luminaries of a networked lighting system. A basic idea of the invention is to provide an efficient and flexible multicast, particularly groupcast message that addresses several or a group of luminaires, and that can control the addressed luminaries in an efficient way by compressing the distributed light settings using a function in order to reduce the communicational overhead. An embodiment of the invention relates to a method for controlling a networked lighting system comprising the steps ofselecting several controllable luminaries of the networked lighting system (S10),combining control information for each one of the selected luminaries to a set of control information (S12),selecting at least one predetermined function for compressing the set of control information by associating an input related to a selected controllable luminary to the control information for the selected controllable luminary from the set of control information (S14),creating a multicast message addressed to the selected luminaries and comprising information regarding the selected predetermined function (S16), andtransmitting the created multicast message (S18).
