Abstract:
AC LED light engines powered directly from the AC power line contain circuitry of resistors, capacitors, diodes and transistors which enables an array of LEDs to efficiently produce light with a relatively low level of flicker as perceived by the human eye. The LEDs are driven by a current which is alternately capacitively-limited and resistively-limited. Capacitively-limited pulses of current are combined with resistively-limited pulses of current so that the resulting output current ripple is at frequencies of 240 Hz or above which the human eye cannot perceive. The combination of resistively-limited current and capacitively-limited current results in a current drain from the power line which is generally sinusoidal and can have a power factor in excess of 0.90, and a flicker index below 0.2.

Claim (Index 4):
The driverless LED light engine defined in  claim 1  further comprising:\n a second bridge rectifier; and \n a second plurality of LED devices connected in series to form a second LED string, connected to the ac power line through the second bridge rectifier, which is activated during any portion of the power line voltage cycle when the current in the first LED string is at a minimum.
