Abstract:
1. An alternating current (AC) light emitting diode (LED) apparatus comprising: a substrate; a first bonding pad disposed on the substrate and configured to receive a first voltage; a second bonding pad disposed on the substrate and configured to receive a second voltage; a first row of LEDs disposed on the substrate and electrically connected to the first and second bonding pads, a portion of the LEDs configured to emit light only when the first voltage is received, and the remaining LEDs configured to emit light only when the second voltage is received; a second row of LEDs disposed on the substrate, electrically connected to the first and second bonding pads, and configured to emit light when the first voltage is received and when the second voltage is received; a third row of LEDs disposed on the substrate and electrically connected to the first and second bonding pads, a portion of the LEDs configured to emit light only when the second voltage is received, and the remaining LEDs configured to emit light only when the first voltage is received; and a first conductor to directly electrically connect anode terminals of a corresponding pair of the LEDs in the first row with cathode terminals of a corresponding pair of the LEDs in the third row, the first conductor being electrically insulated from the LEDs in the second row, wherein the second row is arranged between the first row and the third row.
