Title: Charles F McConaghy: Innovator in Ultraminiature Light Sources
Introduction
Charles F McConaghy is a notable inventor based in Livermore, CA (US). He has made significant contributions to the field of light source technology, holding a total of 5 patents. His work focuses on ultraminiature light sources that utilize innovative filament designs.
Latest Patents
One of McConaghy's latest patents is for an ultraminiature broadband light source with a spiral-shaped filament. This invention features a double-spiral tungsten filament with end contact portions that are separated to allow for both radial and length-wise unwinding of the spiral. The design ensures that the filament does not make contact with itself upon expansion, which enhances its functionality. The light source is constructed by fabricating the filament from tungsten foil and housing it in a ceramic package that has a reflective bottom and a well for filament suspension. A vacuum furnace brazing process is used to attach the filament to the ceramic package's contacts. Finally, a cover with a transparent window is soldered onto the top of the package, creating a complete hermetically sealed unit.
Another patent by McConaghy is for an ultraminiature broadband light source and method of manufacturing the same. This patent shares similar features with the previous one, emphasizing the innovative use of a double-spiral tungsten filament and the meticulous construction process that ensures the light source's efficiency and reliability.
