I would like to ask the master to sell LED ceiling lamp, two lines are not divided into FireWire, zero how to connect security?
Due to step-down rectification, filtering into low-voltage DC to LE D lamp work. So you don't have to fire the zero line.
Each lamp has power, 2 wire light can, and if received, no matter, the current is very small, will not break the light, nor light.
The power supply 220V can be divided into FireWire zero line. Connect the positive and negative lines of the LED light.
220V alternating current into the line as long as the switch is off line, communication line is not part of the lamp wire and the zero line, but after driving after will be divided into DC, positive and negative, if it is to buy, directly connected to the line.
