Abstract
An incandescent lamp has incorporated a circuit board within a recess in the bulb, wherein the circuit board contains connections and circuitry to control power to the lamp filament while maintaining the attachment of the bulb to the metal base, wherein the completed lamp assembly including the circuit board and the metal base maintains the external physical dimensions to fit into standard incandescent light fixtures. The circuitry on the circuit board contains performance-modifying or performance-monitoring electronic circuitry configured to reflect the restrictive size and thermal considerations while employing designs and manufacturing processes most typically found in such products.
