Abstract
A system is described for providing unconditioned power using an alternating current (AC) power source in order to power light emitting diodes (LEDs). The system may include a plurality of light emitting diodes (LEDs), a microprocessor to send pulse-width modulated power signals to power the plurality of LEDs, a zener diode to limit a voltage provided to the microprocessor from the AC power source, and a varistor in series with the zener diode to clamp down the voltage from the AC power source to a pre-defined value to resist current in rush to the microprocessor.
