Abstract
A lamp assembly includes a sealed lamp envelope enclosing a filament, a screw shell connected to the lower portion of the envelope, and electrical leads extending from the filament into the screw shell. The screw shell has a bottom opening, in which is mounted an electronic control module. The electronic module is retained in the screw shell by an insulator. A spring is compressed between the electronic module and an exhaust tube on the lower portion of the envelope. One electrical lead is electrically coupled from the module through the spring to the filament, allowing the module to control the filament. The insulator defines a cavity for retention of the electronic module in a fixed position.
