Thread: Led pannel with rebel led's

    Default Led pannel with rebel led's

    hi there im new here and couldnt find what i was looking for in other threads

    im making a led panel with rebel led all 3w

    im using 3 x led drivers which produce 20-40 v

    i have split the panel into 3 sections to run 3 sets of 10 leds per led driver.
    i have 2 of the 3 sets working but the last set is just flickering when i turn it on.
    if i switch off the power they flicker for 5 seconds then light up propperly for a split second then turn off.
    if i turn the power back on the split second they light up they come on as normal.
    just wondering if any1 knows where im going wrong here as the other 2 sets work fine.
    ive tried the other led drivers but i get the same flickering problem.
    thanks.

    What is your power source? It's possible your power source can't push enough current to run that many LEDs at the same time.
    We all have to start somewhere. The journey is all the more impressive by our humble beginnings.

    hi silver cheers for the response.
    the led driver is working from the mains (AC) which i believe is 230v (UK) and the led driver converts the ac to dc which is 20-40v.
    just cant under stand why 2 sets of 10 leds work with the other led drivers but this set doesnt.

    think i found the problem.
    i added another led to the 1 set that wasnt working (11 instead of 10 led's)
    and it appears to be working now.

    cheers anyway.

    Glad to hear you got it working.
