ABSTRACT:
A first LED array including a first capacitor, LED blocks, and a second capacitor that are connected in series with each other, a second LED array having a similar configuration to the first LED array, and a third LED array having a similar configuration to the first LED array are connected in parallel with each other and are connected to an AC power supply AC. Each of the LED blocks includes a first series circuit and a second series circuit that are connected in parallel with each other. The first series circuit includes two LEDs that are connected in series with each other in the same direction. The second series circuit includes two LEDs that are connected in series with each other in an identical direction opposite to the direction of the LEDs in the first series circuit. A connection point between the two LEDs in the second series circuit in one of the adjacent LED blocks is coupled to a connection point between the two LEDs in the first series circuit in the other one of the adjacent LED blocks.
