Abstract
A light bulb assembly is described. The light bulb assembly includes a bridge rectifier to perform full wave rectification of an alternating current (AC) power source, a capacitor to smooth a voltage from the bridge rectifier, and a plurality of light emitting diodes (LEDs) arranged in series. A number of LEDs included in the light bulb assembly is selected by substantially balancing the voltage from the AC power source with a predefined voltage drop associated with each of the LEDs to consume the voltage entirely using the LEDs to generate light.
