Claim of US Patent No. 10,098,199

1. A lamp control system comprising:a logic module that includes
an interface configured to couple with a lighting source having multiple color channels,
non-volatile memory configured to store a color model,
a processor configured to compute flux ratios from the multiple color channels based on the color model, and
a control signal driver configured to send the computed flux ratios as control signals to the lighting source via the interface; and
a light emitting diode-based (LED-based) lamp that includes
an interface configured to couple with the logic module,
two or more color strings, each color string comprising one or more light emitting diodes (LEDs) of a substantially similar color,
non-volatile memory configured to store at least one spectral power density (SPD) distribution summary characterizing each color string,
an optical sensor configured to measure brightness levels of the two or more color strings, and
a processor configured to send at least a subset of the measured brightness levels and the SPD distribution summaries to the logic module via the interface.
