Title: Innovations of Roger A. Johnson
Introduction
Roger A. Johnson is an accomplished inventor based in Grafton, NH (US). He has made significant contributions to the field of lighting technology, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is for a lamp assembly utilizing a shield and ceramic fiber mesh for containment. This double-enveloped lamp assembly includes a light-source capsule that is subject to burst on rare occasions. A light-transmissive shield surrounds the light-source capsule, absorbing and dissipating energy when a burst occurs. The mesh of nonconducting ceramic fibers reinforces the shield, minimizing sodium migration and making it particularly useful for high wattage lamps where thick-walled outer envelopes are impractical.
Another notable patent is for an electrode feedthrough assembly for an arc discharge lamp. This ceramic arc tube assembly features openings for electrode feedthroughs at opposite ends. Each feedthrough comprises a niobium tube with a tungsten electrode welded to it. The connection wire is pre-welded to the feedthrough, allowing for a shorter design without risking damage during welding. This innovation significantly reduces feedthrough material costs.
