Automatic targeted illumination based on aggregate illumination from multiple light sources

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computing device to cause the computing device to:

• determine a localized area of a defined physical location based on an image of the defined physical location;
• determine a desired level of brightness for the localized area based on user input;
• calculate an illumination level at the localized area based on current illumination levels of lighting devices within the defined physical location, and locations of the lighting devices within the defined physical location;
• generate instructions to effect a change in one or more of the lighting devices, wherein the change in the one or more lighting devices results in the desired level of brightness for the localized area;
• and
• send the instructions to at least one controller of the one or more lighting devices.

A system comprising:

• a processor, a computer readable memory and a computer readable storage medium associated with a computing device;
• a plurality of lighting devices within a defined physical location;
• program instructions to determine a localized area of the defined physical location based on data received by the computing device;
• program instructions to determine a desired level of brightness for the localized area;
• program instructions to calculate an illumination level at the localized area based on current illumination levels of the lighting devices and locations of the lighting devices within the defined physical location;
• program instructions to generate instructions to effect a change in one or more of the lighting devices, wherein the change in the one or more lighting devices results in the desired level of brightness for the localized area;
• and
• program instructions to send the instructions to at least one controller of the one or more lighting devices;
• wherein the program instructions are stored on the computer readable storage medium for execution by the processor via the computer readable memory.
