Environment controller and method for proportionally adjusting the light intensity of several lighting devices

A method for proportionally adjusting a respective light intensity of a plurality of lighting devices, the method comprising:

• determining by a processing unit of an environment controller a current light intensity for each one of the plurality of lighting devices;
• determining by the processing unit of the environment controller a current average light intensity of the plurality of lighting devices by calculating the average of the current light intensities;
• receiving by the processing unit of the environment controller a target average light intensity of the plurality of lighting devices from a computing device via a communication interface of the environment controller or from a user via a user interface of the environment controller;
• and
• calculating by the processing unit of the environment controller a new light intensity for each one of the plurality of lighting devices by proportionally adjusting the light intensity of each one of the plurality of lighting devices from its respective current light intensity to its respective new light intensity so that the average of the new light intensities is equal to the target average light intensity of the plurality of lighting devices, the proportional adjustment being performed by an algorithm which calculates each new light intensity based at least on the corresponding current light intensity, the current average light intensity of the plurality of lighting devices and the target average light intensity of the plurality of lighting devices.

A non-transitory computer program product comprising instructions executable by a processing unit of an environment controller, the execution of the instructions by the processing unit of the environment controller providing for adjusting a respective light intensity of a plurality of lighting devices by:

• determining by a processing unit of an environment controller a current light intensity for each one of the plurality of lighting devices;
• determining by the processing unit of the environment controller a current average light intensity of the plurality of lighting devices by calculating the average of the current light intensities;
• receiving by the processing unit of the environment controller a target average light intensity of the plurality of lighting devices from a computing device via a communication interface of the environment controller or from a user via a user interface of the environment controller;
• and
• calculating by the processing unit of the environment controller a new light intensity for each one of the plurality of lighting devices by proportionally adjusting the light intensity of each one of the plurality of lighting devices from its respective current light intensity to its respective new light intensity so that the average of the new light intensities is equal to the target average light intensity of the plurality of lighting devices, the proportional adjustment being performed by an algorithm which calculates each new light intensity based at least on the corresponding current light intensity, the current average light intensity of the plurality of lighting devices and the target average light intensity of the plurality of lighting devices.
