Architectures for light emitting diode (LED) lighting systems

A lamp control system comprising:

• a driverless light emitting diode-based (LED-based) lamp that includes
• one or more color strings, each color string comprising one or more light emitting diodes (LEDs) of a substantially similar color, and
• an optical sensor configured to generate readings specifying a brightness level of each of the one or more color strings;
• and
• a logic module that includes
• non-volatile memory configured to store a color model,
• a processor configured to determine appropriate adjustments for the driverless LED-based lamp based at least in part on the color model, the optical sensor readings, and one or more spectral power density (SPD) distribution summaries for the one or more color strings, and
• a control signal driver configured to send the appropriate adjustments as control signals to the driverless LED-based lamp.

A method comprising:

• generating a color model for a light emitting diode-based (LED-based) lamp having multiple color strings by
• creating a series of spectral power density (SPD) distribution summaries for each color string,
• wherein each SPD distribution summary characterizes a particular color string at a certain set of operating conditions;
• storing the series of SPD distribution summaries in a non-volatile memory of the LED-based lamp;
• determining a current operating condition of the LED-based lamp;
• identifying a particular SPD distribution summary corresponding to the current operating condition;
• transmitting the current operating condition and the particular SPD distribution summary to a logic module coupled to the LED-based lamp;
• identifying, by the logic module, a corrective adjustment for at least one of the multiple color strings based on the current operating condition and the particular SPD distribution summary;
• transmitting, by the logic module, a control signal representing the corrective adjustment to the LED-based lamp.
