Systems, methods, and devices for creating a custom output spectral power distribution

A lighting system comprising:

• a lighting fixture including a plurality of light sources;
• and
• a controller connected to the plurality of light sources, the controller including a processor and a memory, the controller configured to:
• multiply a first spectral power distribution by a second spectral power distribution to determine a product spectral power distribution,
• multiply the product spectral power distribution by an illuminant spectral power distribution to determine a target output spectral power distribution at a target chromaticity, and
• drive the plurality of light sources at intensities corresponding to the target output spectral power distribution.

A lighting system comprising:

• a lighting fixture including a plurality of light sources;
• and
• a controller connected to the plurality of light sources, the controller including a processor and a memory, the controller configured to:
• exponentiate a first spectral power distribution by an exponent to determine an exponential spectral power distribution,
• multiply the exponential spectral power distribution by an illuminant spectral power distribution to determine a target output spectral power distribution at a target chromaticity, and
• drive the plurality of light sources at intensities corresponding to the target output spectral power distribution.
