Abstract
A modular LED light bulb is presented. The bulb comprises a bulb envelope and a removable screw base. A power supply within the bulb envelope connects to an electrolytic capacitor within the screw base. When the electrolytic capacitor in the screw base requires replacement, the screw base is detached from the bulb envelope, the depleted electrolytic capacitor is discarded, and a new electrolytic capacitor is connected to the power supply. The various embodiments increase the useful life of the LED light bulb. In another aspect, the screw base may be adapted to accept swappable modules to provide the light bulb with additional functionality. The swappable modules may provide the light bulb with wireless control and motion sensing.
