Latest Patents

One of her latest patents is for a mercury-free metal halide arc lamp. This lamp features an arc vessel made of fused silica, an aspect ratio greater than 5, and contains noble gases such as xenon, argon, or krypton along with metal halides. In a preferred embodiment, the arc vessel has a diameter of 8 mm and a length of 80 mm, filled with sodium/scandium iodides and a buffer gas of xenon. Another significant patent involves a chemical composition for mercury-free metal halide lamps. This invention demonstrates that rare-earth halides can replace scandium halides in mercury-free discharge arc lamps, provided that modifications are made to the lamp design and operating temperatures. The unique chemical compositions of the discharge medium enhance color rendition index values. Furthermore, it has been found that during operation, rare earth iodides do not significantly react with the fused silica arc tube, leading to longer lifetimes and superior illumination characteristics compared to conventional discharge lamps.
