1. Zero live wire connection does not distinguish (that is, live wire and zero wire are casually connected).
2. Distinguish between neutral wire and connection mode. The fire line is generally red or white, and the zero line is generally black. Double ballast connection: two brown wires are connected to the live wire, two blue wires are connected to the zero wire, and the other two wires (the grounding colors of the double ballasts can be the same or different) are grounded.
I don't know if your LED full-color bead is anode or cathode, so it should be used with the corresponding anode or cathode controller. * * * Anodes are used more. Under normal circumstances, the four lines on the LED colored beads are yellow, red, green and blue. The yellow is connected to the male * * * pole (* * * Yang is the positive pole+,* * Yin is the negative pole-), the red line is connected to the red control line on the controller (generally marked as R), the green line is connected to the green control line on the controller (generally marked as G), and the blue line is connected to the blue control line on the controller (generally marked as B). Red, green and blue can't be connected casually. If you connect them casually,
If there are four wires, you must know whether your lamp is polychromatic or monochromatic. If it is a multi-color lamp, the driver must also have four output leads, one of which is a * * * positive electrode (positive electrode) or a * * * negative electrode (negative electrode), and the other three are colored wires. If it is a monochromatic light, is there any touch or other function? Generally, three wires are connected to live wire, neutral wire and ground wire, and the other wire is connected to functional wire (connected to driver).
