Classification: CPC H | IPC H

Claim 0:
1. A lighting device, comprising:
a current source generating a current;
a first load and a second load receiving the current;
a first semiconductor and a second semiconductor managing the current flowing to the first load and the second load, respectively;
an inductor positioned between the current source and the first and second loads to balance the current between the first and second loads;
a detector monitoring a voltage peak from the current source to the first and second loads; and
a voltage controller receiving a reading of the voltage peak from the detector and determining when the voltage peak is at least a voltage peak threshold, the voltage controller configured to adjust a setting for the current generated by the current source based on the reading of the voltage peak;
a comparator receiving a further reading of the voltage peak from a further detector and determining when the voltage peak is at least a comparator threshold when one of the first load and the second load has failed resulting in an open circuit and the other one of the first load and the second load remains functional, the functional load experiencing the voltage peak that is at least the voltage peak threshold, the comparator configured to generate a signal when the voltage peak is at least the comparator threshold; and
a semiconductor controller configured to receive the signal and deactivate the first and second semiconductors.
