Light emitting diodes for high AC voltage operation and general lighting

A light source comprising:

• a single-chip integrated LED device having a first plurality of series connected LEDs having a forward biased direction of current flow, and a second plurality of series connected LEDs having a forward biased direction of current flow,
• said first and second pluralities of LEDs connected together such that said respective forward biased directions of current flow are opposing,
• structure for connecting said first and second pluralities of LEDs across an AC power source, and
• wherein said first plurality of series connected LEDs and said second plurality of series connected LEDs are flip-chip bonded to a submount,
• whereby said first and second pluralities of LEDs are alternatively energized by said AC power source.

A light source comprising:

• a single-chip integrated LED device having an array of series-connected LEDs having a forward biased direction of current flow and presenting positive and negative terminals,
• said terminals of said single-chip integrated LED device adapted to be connected across an AC power source, and
• wherein said array of series-connected LEDs are flip-chip bonded to a submount,
• whereby a current from said AC power source energizes said array of series-connected LEDs in said forward biased direction during a first half cycle of the AC power source cycle.

A light source comprising:

• a single-chip integrated device having a plurality of pairs of LEDs, each of said pairs of LEDs a first LED having a first forward biased direction of current flow and a second LED having a second forward biased direction of current flow, said first LED connected to said second LED opposite said second forward biased direction of current flow, said plurality of pairs of LEDs connected in series,
• structure adapted to connect said plurality of pairs of LEDs across an AC power source, and
• wherein said plurality of pairs of LEDs are flip-chip bonded to a submount,
• whereby a current from said AC power source energizes said plurality of first LEDs in said first forward biased direction during a first half cycle of the AC power source cycle and said plurality of second LEDs in said second forward biased direction during a second half cycle of the AC power source cycle.
