If you had a string of LED's, or really any LED for that matter, how would you protect them from overheating?
In one of my projects, I am finding that if left on for days they can get very warm and the diodes start to lose intensity. What I also notice that even though they are not as bright as they were when new, they seem to dump the same amount of heat into the fixture.
In my setup, the LED's are drawing about 1 amp of current total, at 12v. Is there a special type of thermal resistor I could use that would automatically pull back current when temperatures hit a certain point?
If not, I think I might have to lower the overall voltage a bit...
