We are currently seeing some issues with an LED driver circuit.
I am not sure about root cause because there are too many variables.
During operation the LEDs are dim or do not light at all (after 2-3 months in operation.)
Attached is the portion of the driver circuit for the LED.
Any ideas that would cause excessive electrical stress in the form of excessive current applied to the LED or the LED to be dimmed or damaged? What would cause excessive current, besides a short? We have too many LEDs being damaged or going dim.
