With four patents to his name, McMillan's work focuses on enhancing the performance and safety of electric lamps, showcasing his dedication to innovation and engineering excellence.

Latest Patents

Among McMillan's latest patents is the groundbreaking "Electric Lamp with External Fuse Lead." This innovative design outlines an electric lamp construction that utilizes a pair of conductive inlead wires made from dispersion-strengthened copper alloy, ensuring that these wires serve as the primary means of physical support for the resistive incandescent filament. A notable feature of this invention is the incorporation of a fuse lead made from a copper solution alloy with nickel and tin, which minimizes arc damage during lamp operation compared to other commercial fuse metals.

Another recent patent is the "Inlead Construction for Electric Lamp," which introduces an improved inlead wire construction utilizing an iron alloy. This alloy's sufficient silicon content prevents the transformation of the inlead from the alpha ferrite phase to the gamma austenite phase at operational temperatures. By doing so, McMillan's invention addresses issues of debilitating deformation caused by on-off cycling of the lamp, thereby reducing the risk of structural or operational failures during use.
