CPC H05B 45/37 (2020.01) [H05B 45/10 (2020.01); H05B 45/48 (2020.01); H05B 45/50 (2020.01)] | 8 Claims |
1. A system for emitting light, the system comprising:
a first light emitting diode (LED) string comprising one or more LEDs that are electrically connected in series;
a first LED driver that is electrically connected in parallel to the first LED string;
a first voltage sensor positioned to measure voltage in a conductive path between the first LED driver and the first LED string;
a second LED string comprising one or more LEDs that are electrically connected in series;
a second LED driver that is electrically connected in parallel to the second LED string;
a second voltage sensor positioned to measure voltage in a conductive path between the second LED driver and the second LED string;
a first switch that is configured to close and positioned to create a conductive path between the first LED driver and the second LED string when the voltage measured by the first voltage sensor is more than a threshold level above the voltage measured by the second voltage sensor; and
a second switch that is configured to close and positioned to create a conductive path between the second LED driver and the first LED string when the voltage measured by the second voltage sensor is more than a threshold level above the voltage measured by the first voltage sensor.
