Detecting LED failure conditions

A method for controlling a plurality of light emitting diodes (LEDs), the method comprising:

• controlling whether an LED of the plurality of LEDs receives a first electrical signal from a first power source;
• receiving, by a node, a second electrical signal from a second power source;
• determining, by processing circuitry, that the LED is associated with a bright failure condition by attempting to prevent the LED from receiving the first electrical signal from the f power source using a switching device, wherein the switching device is electrically connected to the LED;
• and disabling, by the processing circuitry, the LED in response to detecting the bright failure condition, wherein disabling the LED comprises causing the node to deliver the second electrical signal to the LED in order to permanently prevent the LED from emitting photons.

A system for controlling a plurality of light emitting diodes a (LEDs), the system comprising:

• the plurality of LEDs;
• a switching device, wherein the switching device is electrically connected to an LED of the plurality of LEDs, and wherein the switching device is configured to control whether the LED receives a first electrical signal from a first power source;
• a node configured to receive a second electrical signal from a second power source;
• and
• processing circuitry configured to:
• determine that the LED is associated with a bright failure condition by attempting to prevent the LED from receiving the first electrical signal from the first power source using the switching device;
• and
• disable the LED in response to detecting the bright failure condition, wherein to disable the LED, the processing circuitry is configured to cause the node to deliver the second electrical signal to the LED in order to permanently prevent the LED from emitting photons.
