Incandescent lamp with integral controlling means
First Claim
1. An incandescent lamp assembly having a glass arranged with a recess wherein first and second electrical leads exit the envelope via gas tight seals, and wherein the envelope extends around the recess, the extension and recess arranged for receiving a socket, wherein the socket is arranged for receiving third and fourth electrical leads and continuing the electrical connections from the third and fourth electrical leads to two external power source connections, the lamp assembly further comprising:
- a circuit board molded to fit within the envelope recess, means for making electrical contact from the circuit board to at least one of the first and second electrical leads, means for making an electrical contact from to at least one of the third or fourth electrical leads to the circuit board, an electrical circuit arranged on the circuit board for controlling the power to the lamp filament, wherein the completed lamp assembly including the circuit board maintains and a metal base wherein the external physical dimensions of the assembly fits into standard incandescent light fixtures.

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.
