Abstract
According to an embodiment of the present disclosure, a plurality of light-emitting diode (LED) modules in series are monitored. When an LED module is detected as failing or operating inadequately, a bypass switch removes the particular LED module from the series and the voltage provided to the series is modified. When the LED modules are detected as having too high of a temperature, the current provided to the LED modules is limited.
