Hey there everyone.
I have a need to protect some LED's from overheating, and I have some thermal switches that work well but I would like to dim the LED automatically rather then them shutting off completely.
What type of circuit do manufacturers use to do this? I was thinking maybe just a simple thermistor pushing on a FET to drive the current?
The powers supply source is 12VDC running about 1a of lights. Its those string lites so the current limiting resistors are built into the strip.
thanks for any help
