LED panel, step 1

I received 1000 clear white, daylight balances LED’s today in the mail and quickly set about screwing some of them up.  Apparently, when you have an LED that is rated for 3.4 volts(V) and you hook it up to a 9V battery, well, it burns it out.  So, I now have 996 LEDs.  Anyways, Im wading through all of the electrical connections and the math involved with it and I think that I have it down.  I still need to decide on either a 12V power supply or a 20V supply.  Its not a huge deal and I guess I will go with the 12V to be safe.  I have also figured out that I need to run these in parallel rather than series.  All in all, almost ready to start soldering.

Still on the shopping list…

About 400 resistors

Main Wire

Electrical tape

Soldering Gun/Solder

Some sort of perforated board to hold the LED’s (ideas here?  Unfortunately peg board will not work)

Power supply

    • So far the LED”s were $55.00. I have to buy resistors (about 200) and that will be $10.00 and a power supply ($20.00) and a soldering iron and solder ($20.00). Im thinking of putting a variator on it ($10.00) so I can dim it and still have to figure out a material to use as the board that they will all mount to ($30.00 ?). All told, a hell of a lot less than they are to buy. Want to buy one if they turn out well?

  1. Lite Panels are priced extremely high for what they are but they’re used all the time now in the motion picture world. I’ve got friends who own them and rent them on every job.
    Lite Panels has a source for high quality led’s that are color matched quite well. The problem with bulk led’s that we can buy is the color matching from led to led. I hope yours work out well.

    • I can’t really understand why they cost so much other than the fact that wring them is time consuming. I’m sure the LEDs I bought cost much, much less but all told, the components in a litepanel are really not that expensive. As far as the color accusrcy goes, I’m nor really too concerned about it. In fact, I was thinking about wiring in a 60/40 mix of daylight an warm white LEDs so as to mix the light a bit and warm things up. Maybe next time.
