I think the connection is made at the actual negatives of the SMD LEDs. I drew up what I theorized the connection to be a while ago in CAD:
You can have 4 separate contacts on the board, one for each LED, and by shorting the two adjacent ones with a small amount of solder during the SMD soldering process you can use the same star layout for stars with 2 negative wires or 4. This, for me, explains how the company could not only use the same LED star for RGBA, 6/6/12 and single color LEDs, and may also explain why the single color modules use two negative wires. If this is the case, either pad could be used for each side of the module. Snakeeyz99, I found a post by Kouri on a different topic that might explain a few things: From "A Great Deal To Learn About LED's I Have" Thread Kouri wrote:
All positives are linked on the X2/X4 stars, so it doesn't matter if you use one, the other, or both positive pads.
That said, I think what you have is an X2, not an X4 star. The naming's a bit confusing, because either is capable of holding 4 LEDs, but the X2 has only two selectable channels (with negatives doubled up on each channel). If this was an X4, the star would have one positive and all four negatives soldered... ...based on this, there are 2 different star (LED board) configurations. Wonder if we can request X2 or X4 boards when we purchase SF 12W+ LED modules... |
