Abstract

A current driver for powering an LED assembly comprises an input capacitor and a full wave rectifier. The LED assembly is connected to the rectifier output terminals. A driven LED assembly may be formed of series and parallel strings of individual LEDs. AC Line frequencies, e.g., 50 cycles, 60 cycles, non-line AC frequencies; and ranges of source voltages, e.g., 120 to 220 volts are accommodated by the driver. The driver provides essentially equal energy current pulses to the LED load, coincident with the time and the duration of the positive excursions of the input power. Energy is delivered to the LED load in a 50% duty cycle. Transfer of energy from an AC input power source to an LED assembly is independent of the output parameters of that source.
