In one embodiment there is provided an ambient lighting control systemcomprising a controller () and a sensor node (). The sensor node () comprises an arrangement including a light energy collecting element () such as a solar cell, an energy storage element () and a transmitter (). The collecting element () charges the storage element (). The transmitter () is arranged to transmit signals to the controller () using energy stored by the energy storage element (), wherein the number of signals provided during a time interval to the controller () is proportional to a light intensity at the light energy collecting element (). The controller () may thus output a control signal C for controlling an amount of ambient lighting, wherein the control signal is based on the determined number of received signals.

Ambient lighting control system

The invention relates to automatically configuring of a lighting created by a lighting system, particularly to creating a lighting, which follows a person, with a networked lighting system. A basic idea of the invention is to adapt the learning based processing of activations of lamps and presence detectors received as input data to changes in a system for automatically configuring lighting with a variable adaptation rate in order to make the automatic lighting configuration more robust with regard to system changes. An embodiment of the invention relates to a system () for automatically configuring a lighting, wherein the system comprises&#x2014;a network of lamps (), wherein each lamp is activated by a control signal and outputs its activation, &#x2014;a network of presence detectors (), wherein each presence detector is activated by detecting an activity and outputs its activation, and&#x2014;a lighting configurator () for processing activations of lamps and presence detectors received as input data () based on learning and outputting control signals () for lamps depending on the processed input data for configuring the lighting, wherein the processing of input data by the lighting configurator can be adapted to changes in the system with a variable adaptation rate ().

System and method for automatically creating a lighting effect

The invention relates to automatically configuring of a lighting, particularly to creating a lighting, which follows a person, with a networked lighting system. A basic idea of the invention is to configure lighting in a network of lamps in that a lamp of the network adjusts its light emission depending on presence detection in its own direct environment and the presence detected in the environment of other lamps of the network. An embodiment of the invention relates to a system () for automatically configuring a lighting, wherein the system comprises The invention allows automatically configuring a lighting with a network of lamps for a certain area in that lights go on before a person gets to a certain area.
