Weird LEDs...

[zephyr1220]

I've intalled leds for my cousins psp but something weird happened...
The blue leds had a faint green coloring even the white ones,
It emits green light why is this happening?
Should i be bothered about this...

bad batch of LEDs. it happens.

when they dope the semiconductor material sometimes it doesn't mix well and there is an unevenly blended semiconductor.

Another cause is the forward voltage could be too high and the led changes color because of too much heat. (use a resistor).

Finally today they all sparked hehehe...
I think its bad batch of leds, i am using the batt to test it.
well gonna buy a new one, thanks

if they sparked as in "popped" you are using too much voltage...

yeah it goes like this:
Blue light then blue and faint green then i think i saw a spark then poof!

Anyway thanks for the info guys good thing is psp is still alive.

thanks

you need a resistor.
