Open-loop closed-loop integrated daylight and artificial light control with multipoint sensor calibration

A non-transitory computer readable medium having stored thereon instructions for causing a processor to perform a process of controlling light distribution in a lighting system for a space, said lighting system including an artificial light source, at least one blind(s) in the space, a lighting control unit and a daylight/blind control unit, the process comprising:

• estimating illuminance levels of light emitted by the artificial light source and an external/daylight source at a plurality of measuring areas within the space;
• controlling an intensity level of the installed light source and an amount of light from the external light source entering the space based on the estimated illuminance levels;
• and
• determining, in the lighting control unit, a first positioning of the blinds according to predetermined lighting system/user requirements and/or measurements by the lighting system;
• receiving the plurality of measuring areas data within the space;
• determining, in the daylight/blind control unit, a second positioning of the blinds according to predetermined requirements;
• using either the first or second positioning of the blinds according to predetermined criteria to provide optimal daylight comfort, glare prevention and view.
