Abstract
A high-voltage light emitting diode (LED) circuit having a plurality of critical voltages and an LED device using the same are described. The high-voltage LED circuit includes a first substrate, at least a first LED formed on the first substrate, and at least an impedance element formed on the first substrate and electrically connected in series with one end of the first LED. The first LED is connected in parallel with at least a second LED based on the characteristics of the impedance element, and the second LED has a polarity opposite to that of the first LED, such that the high-voltage LED circuit may be operated in an AC power supply environment, thereby improving the convenience of using the LEDs.
