Abstract:
1. A single-chip integrated LED for use with an AC power source comprising: a first plurality of series connected LEDs having a forward biased direction of current flow, a reverse biased direction of no current flow opposite said forward biased direction of current flow, and presenting positive and negative terminals, a second plurality of series connected LEDs having a forward biased direction of current flow, a reverse biased direction of no current flow opposite said forward biased direction of current flow, and presenting positive and negative terminals, said positive terminal of said first plurality of LEDs connected to said negative terminal of said second plurality of LEDs, said negative terminal of said first plurality of LEDs connected to said positive terminal of said second plurality of LEDs, and said terminals of said first and second plurality of LEDs adapted to be connected across said AC power source, whereby a current from said AC power source energizes said first plurality of LEDs in the forward biased direction during a first half cycle of the AC power source and said current from said AC power source energizes said second plurality of LEDs in the forward biased direction during a second half cycle of the AC power source.
