System and method for controlling a plurality of light fixture outputs

摘要

A method of controlling a plurality of light fixtures. The method includes detecting the light outputs of a plurality of light fixtures and detecting a reflection of light from a surface. The light outputs and the reflection of light are analyzed. Differences among the light outputs of the plurality of light fixtures are determined, and a difference between the reflection of light and a desired reflection of light is determined. New or updated values for output color, output brightness, and/or output spectra are determined for the plurality of light fixtures such that the light outputs of the light fixtures are consistent and correspond to a desired light output, and such that the reflection of light corresponds to the desired reflection of light. Each of the plurality of light fixtures is then driven using respective light source output values to produce the desired light outputs.

1. A method of controlling a plurality of light fixtures, the method comprising:
determining a first light output of a first light fixture, the first light output having a first output color, the first output color having a first output spectrum; determining a second light output of a second light fixture, the second light output having a second output color, the second output color having a second output spectrum; detecting a first reflection of light from a surface, the first reflection of light corresponding to light from the first light fixture and the second light fixture that is reflected off of the surface; analyzing the first reflection of light to determine a spectrum of the light reflected off of the surface; determining a difference in color between the first light output and the second light output; determining a difference between the spectrum of the light reflected off of the surface and a desired spectrum of the light reflected off of the surface; when a difference in color between the first light output and the second light output is identified, calculating an updated output color of at least one of the first light fixture and the second light fixture such that the first output color substantially matches the second output color; when a difference in the spectrum of the light reflected off of the surface and the desired spectrum of the light reflected off of the surface is identified, calculating an updated output spectrum for at least one of the first light fixture and the second light fixture such that the first output spectrum substantially matches the second output spectrum without further changing the first output color, or the second output color; determining a respective light source output value for each light source in each of the first light fixture and the second light fixture such that the first output color substantially matches the second output color, the first output spectrum substantially matches the second output spectrum; and driving each of the light sources in each of the first light fixture and the second light fixture at the respective light source output value.
