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 11):
The driverless LED light engine as defined in  claim 8  in which at least a third rectifier diode is connected in antiparallel with an LED substring disposed between a connection of said first capacitor and the midpoint of the LED string, and at least a fourth rectifier diode is connected in antiparallel with a separate LED sub string disposed between a connection of said second capacitor and the midpoint of the LED string.
