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 14):
The method of  claim 13 , wherein calculating the operational age of the light engine comprises:\n varying the forward voltage across the light engine while sampling the forward voltage and the forward current; and calculating a transition voltage from the sampled forward voltage and forward current.
