General LED packaging factory, 1, 3, 5 pins for the positive electrode of the three chips, 2, 4, 6 pins for the negative electrode of the three chips.
The triangle notch is the MARK point, and the RGB bead triangle side is the positive pole. Monochromatic light or white light sealed triangle edge is generally defined as the negative electrode, this is not absolute, depending on the supplier's acknowledgement. 1 to 2 pins are green\/blue LED chips, 3 to 4 pins are red LED chips, and 5 to 6 pins are green\/blue LED chips. Multiple LED lamp beads are generally connected by series and parallel circuits, so according to your power supply to design several series and several, but also add current limiting resistance on each chip circuit. Red light has the smallest VF, and the current limiting resistance is relatively larger, and green light and blue light VF are almost the same, and the current limiting resistance is the same
