Greetings & Salutations,
I am trying to make an LED light Board if you will. I want to pack about 100-200 LEDs onto a PCB board. The intended use case is described in this video. I cannot figure out a few basic things which is understandable since I am a n00b.
1. How does one apply power to a PCB? Is there designated bus? I've seen people attached aligator clips to some but I cannot get this to work.
2. I think I want to deploy the LEDs in parallel allowing the other LEDs to function if one goes out. Series=one big loop where one point of failure causes everything to fail doesn't make too much sense.
3, I'd like to have portable PS like a battery but I am not sure how to calculate how much power my 100 LEDs simultaneously require. Can I power 100 LEDs of some type of battery?
4. The longer-lead on the LED is the POS as I understand it. Do i have to put these in a certain way on the board?
5. Do I need resistors?
6. Do I solder the 2 leads to solely to the PCB or do solder them to the board and each other? If so, then POS lead to POS Llead?
Right now I've only been able to solder 4 LEDs to my board. I did so in 2 sets with 2 LEDs each. 2 are connected horizontally and 2 vertically. I can take my 22AGE leads from the PS and make the LEDs light up by touching the leads to the solder leads from the LED. I can get them all to light up but not all at once.
I thought I would be able to somehow take my power supply leads and attach them to the PCB would would then supply power to all LEDs on the boards.
Parts:
Grid-Style PC Board with 750 Holes Radio Shack 276-0158
LED Uni-Color Red 660nm 2-Pin T-1 3/4
Power Supply: 2AMP Regulated DC PS MW122A | Set @ 3V
22 AWG solid wire
Here are a few photos of what I'm doing. Warning...very rudimentary.
