Abstract:
A luminaire includes a microcontroller and program logic that calculates the operational age of a light engine that includes a plurality of light emitting diodes connected in series. The program logic uses changes in transition voltage to calculate the operational age of a light engine. Changes in forward voltage across the light engine are used to detect sudden catastrophic failure of individual light emitting diodes. In response to the sudden catastrophic failure of one of the light emitting diodes, the program logic adjusts the power provided to the light engine based on the calculated operational age of the light engine. For example, the operational age of the light engine may be compared with a warrantied lifespan, and the power may be adjusted to increase the likelihood of compliance with the warranty.

Claim (Index 10):
An apparatus comprising:\n a light engine comprising a plurality of light emitting diodes connected in series; a switched-mode power supply that generates an output power that is supplied to the light engine, the switched-mode power supply setting the output power in response to a voltage control signal; and a microcontroller comprising a processor, a memory, an analog-to-digital converter, a digital-to-analog converter, and program logic that is stored in the memory and implemented by the processor; wherein the analog-to-digital converter provides forward voltage across the light engine and forward current through the light engine to the processor, and the program logic uses the forward voltage and forward current to calculate an operational age of the light engine, detect sudden catastrophic failure of one of the light emitting diodes, determine whether the calculated operational age of the light engine is greater than a warrantied operational lifespan, and generate the voltage control signal to cause the power supply to adjust the output power in response to detection of the sudden catastrophic failure of one of the light emitting diodes wherein adjusting the voltage control signal comprises maintaining a luminance that is greater than a warrantied light engine luminance when the calculated operational age of the light engine is greater than the warrantied operational lifespan and maintaining a luminance equal to the warranted light engine luminance when the calculated operational age of the light engine does not exceed the warrantied operational lifespan, the voltage control signal being provided to the power supply by the processor via the digital-to-analog converter.
