Title: Innovations of Jeffrey MacDonagh-Dumler
Introduction
Jeffrey MacDonagh-Dumler is an accomplished inventor based in Cambridge, MA (US). He is known for his innovative contributions to the field of light emission technology. His work focuses on the development of methods and apparatuses that enhance the efficiency of visible light production.
Latest Patents
One of his notable patents is the "Barium light source method and apparatus." This invention allows for visible light emission obtained from a plasma containing elemental barium, which includes neutral barium atoms and barium ion species. The neutral barium provides a strong green light emission in the center of the visible spectrum, achieving a highly efficient conversion of electrical energy into visible light. By selectively exciting barium ionic species, the invention enables the simultaneous emission of visible light at longer and shorter wavelengths alongside the green emission from neutral barium, effectively producing light that is visually perceived as white. The discharge vessel contains elemental barium and a buffer gas fill, with a discharge inducer utilized to induce the desired discharge temperature and barium vapor pressure to produce visible light emission.
