ok i have a few of these LEDs and i dont know what they are for i think they might be IR LED, i have tried putting a power source through them from 3-9V and it does nothing. any ideas at all i have about 500 of these my friend gave me and not a clue what they do...
Did you try looking at them
Did you try looking at them using a camera when they are powered on ? If they are IR they will glow a purple whiteish colour. Use the camera on your phone and test with a TV remote (some cameras might have filters that block out IR light).
thank you but at least that ruled one out…
thank you tired my phone on a tv remote, then tired it on the LED nothing isnt IR then
Or this one?
if you put 9 volts through
if you put 9 volts through that LED it is probably not an LED anymore because it has leaked its magic smoke
*9 volts will convert them to DEDs
*Dark Emitting Diodes
