Abstract:
1. A method for color matching an output of a lighting node comprising a plurality of lamps, the method comprising: receiving at the lighting node a correlated color temperature setting; determining at the lighting node a temperature of the lighting node-utilizing a temperature sensor of the lighting node; determining in the lighting node a luminous flux of a plurality of lamps of the lighting node required to output the received correlated color temperature from the lighting node based on a color mixing plan; determining in the lighting node a current required by each of the plurality of lamps based on the luminous flux, the temperature, and a function for the current used to generate a given luminous flux over a range of luminous flux values and temperatures for each of the plurality of lamps, wherein the function for the current is modeled individually for each of the plurality of lamps; and operating the plurality of lamps with the determined current.
