LIGHTING SYSTEM AND METHOD OF CONTROLLING THE LIGHTING SYSTEM

摘要

A lighting system is provided that has lighting units and sensor units. One of the sensor units is first sensor unit that comprises a user control device for receiving user commands when a user enters the commands at the user control device. The lighting units are controlled according to a lighting plan that defines a group of the lighting units that is to be switched on in response to detection of a user command at the user control device, based on light transfer coefficients relating light intensities at the sensor units to light output from the lighting units. The transfer coefficients from the lighting units to each sensor unit are determined. The lighting plan is determined from the transfer coefficients by selecting the group of lighting units based on the transfer coefficients from the lighting units to the first sensor unit. The transfer coefficients from the lighting units to a sub-set of the sensor units may be used, the sub-set being selected for the first sensor unit, based on the transfer coefficients for the sensor units from an initial group of one or more of the lighting units associated with the first sensor unit.

1. A method of operating a lighting system, wherein the lighting system comprises lighting units and sensor units, at least one of the sensor units being a first sensor unit that comprises a user control device or is coupled to the user control device for receiving user commands when a user enters the commands at the user control device, wherein the lighting units are controlled according to a lighting plan that explicitly or implicitly defines a group of the lighting units that is to be switched on in response to detection of entry of a user command at the user control device, or caused to emit increased light intensity in response to that detection, based on light transfer coefficients relating light intensities at the sensor units to light output from the lighting units, the method comprising that the lighting units and/or sensor units execute the steps of
determining the transfer coefficients from the lighting units to each sensor unit, each transfer coefficient being determined from sensed light intensity variations measured by the sensor unit in correspondence with lighting control variations of a respective one of the lighting units; determining the lighting plan by selecting the group of lighting units based on at least the transfer coefficients from the lighting units to the first sensor unit.
