I've been swapping out some of the LEDs in my case but my TFT flat panel and CDRW both have 3 leg, Green/Orange bicolour LEDs. I've looked about for 3 legged bicolour Blue/Red LEDs but no luck. Does anyone know where I can get these in the UK?
You can't get them in the UK. Believe me, I tried. Try FrozenCPU, or The LED Museum which happens to have some spare on the For Sale page.
This may or may not help, but if they have 3 legs than they are tri-color (2 leds with common anode or cathode), for example a red/green one will appear yellow/orange if both are on at the same time. A Bi-Color is 2 diodes in opposite polarity so when current is one way one color is on, when current is the other way the other color is on.
Have you checked? Do they sell them? (lexeon.com certainly doesn't, because it's a dead link.) Does this actually refer to his question? Sorry to seem pedantic, but really, guys. Let's try to specifically answer his question.
3 Legged LED's aren't always Tri-colored And yes RS stocks bi-color, 3 legged LED's. However NO red/blue ones, which i have never seen before. I'm sure Farnell has bi-colors too, but their online products search is a biatch. I'll have a peek in their almighty 2004 catalogue tomorrow, perhaps they have blue/red ones.
Another option is to use a true RGB LED, and use only the Red and Blue color. These should be widely available. RS p/n: (quite expensive, sure they can be had cheaper elsewhere) 247-1511 diffused 247-1505 clear
No red/blue bi-colors at Farnell too So best bet would be a RGB LED and use only the Red and Blue portion. Found a German shop for these RGB's, way cheaper than RS or Farnell. /perhaps interesting, they have RGB auto-fading led's too, i wonder how that would look when used with the 10 LED HDD activity circuit
There's no red/blue bi- tri-coloured LEDs in the UK anywhere. I've looked thoroughly, and found none. www.ultraleds.co.uk sells some bi-coloured red/blue ones (two legs, swap polarity to change colour) but they are of no use for Awoken's application. ... and then they say Disco is dead...
