Hi all
I'm looking for some assistance as I've been unable to find anything online for what I'm trying to do. I would say I'm a noob when it comes to electronic although I have built a few led lighting fixtures for aquariums, DJ equipment, etc.
What I want to do is build a 200 LED light panel that will strobe in sync with music for my brother's DJ career/birthday. The plan is to run 200 20,000mcd LEDs. Stats are 3.2 voltage drop at 24ma. Voltage source is 15vdc. The array will be 4x50 strings using 100ohm 1/4 watt resistors.
My question is: I found the signal circuit online which uses the tip31 transistor. I picked up a few at radioshack which say they are rated for 5v reverse drop. 40 watts max/3.0 amps.
The designed array will draw 1200MA @ 15 volts which I think turns out to somewhere around 18 watts. I found this circuit diagram off another thread and I'm wondering if this would work.
Any help would be GREATLY appreciated!
