    Default Can anyone identify this LED?

    Hello!

    I've been looking for this LED for a while now, I used to have a link to a site which sells it, but I lost the link when I converted to windows 7. So far I can't find anything on it , nor can two other people.

    If anyone could help me that would be great. It's a 12A ( Per die I believe ) RGBW LED. Looks like this :



    Any help would be greatly appreciated.

    Cheers!

    Adam

    hi


    I got the email reply , the led is 380-RGBW-D11QF 100 company that makes them is luminaus and uk diributer is EBV EleKtroniK


    Good luck with them


    Regards

    I have some of these, actually I have three of the single color ones. The quad die was not released when I bought mine.

    The tough part is driving them. Mine need up to 19A at 2.6v to 3.5v. I had to buy the demo boards and they are not cheap. The diodes themselves are not that bad, mine were about $100.00 each.

    They are stupid bright! Never thought I would see a led smoke plastic.

    Sorry for the bad picture, My Iphone does not like them one bit.

    Nice! is that a picture of the single emitter ones? Were they the ones at $100? I'm thinking of getting them ( PT-120s ). Plan to drive it with an RGB controller chip, MOSFETS, huge resistors and 5V. TEC cooled.

    That's crazy that they smoke plastic!! You make me want them more!

    yup.

    When you do the math I think you will find that big ass resistors becomes an understatement. It really needs to be a buck converter. Also pwm dimming 19A at a couple of volts is harder than it sounds. Lots of inductive problems.
    They also get real hot. You need to have pretty good cooling, especially the red. Don't bother with a tec, just find a good pc cpu heatsink works fine for me.

    I really cannot convey just how fricking bright these are.

    Vari*light just released a wash fixture that is using these.

    Buck converter eh? What buck converter setup did you use? I could probably use a setup with a MOSFET and a dual op amp to do it, I'd just need to work on modulation then. I could probably use an opto isolator before the FET on the LED so that the gate voltage is high enough and to amplify the modulation signal to be large enough for the op amp circuit . Sorting out the inductive problems may be hard, but I'll have a look into it.

    I have a circuit just now that may do the trick, just need to work on inductive problems. I can shield the control circuit with a wire mesh type thing which is tied to ground. That may help.

    Any suggestions?
