I was wondering if leds can be killed by not giving enough volts?

Because I modded my speaker led with a blue led. But after 15 minutes the led faded out and died.

Whats werid is the led was slowly revived by a small 3v battery. I would assume the led adjusts it's power to high volts like 3.7 . But if the volts are too little, it would slowly require more and more volts to light up.

what do you think? BTW I tired this twice, and both times this happened. :roll:

usually when an led is underpowered... it won't light up at all... i've never heard of this happening, though it could be the case. are you sure you didn't overpower them?

Oh i'm very sure i didn't overpower them. The original Led is a 3mm green led which should use less volts than a blue led.

Here is the guide I followed, and the speaker I have is the exact same model. http://www.gideontech.com/guides/led_re ... ex04.shtml

BTW I already played and messed with overpowering leds, this is a different case. :wink:

Usually a blue led uses more volts then a green or tex. a red one...

hmm that is a strange case...unless the LED needed a cetain amperage and it was pulling more then what the green did ...that could explain why the led suddenly faded out when there was a sudden lack of amperage

Well I think this project is a big failure, but hey the speaker still works. Its werid when I put an led in, the subwoofer activates without the speaker on. The death of the led might have been because the subwoofer's power (12V) must have somehow connected to it.

ok thx guys for your help, next time I'll bring something worth showing.
