Title: The Innovative Contributions of Edward Chen
Introduction
Edward Chen is a notable inventor based in Glen Rock, NJ (US). He has made significant contributions to the field of artificial illumination, holding a total of 2 patents. His work focuses on enhancing the efficiency and quality of lighting technology.
Latest Patents
One of Edward Chen's latest patents is a high-intensity-discharge lamp of the mercury-metal halide type. This innovative lamp efficiently illuminates objects with excellent color appearance. The arc tube filling includes an inert, ionizable starting gas and mercury, which is essential for providing a predetermined operating voltage drop between the lamp electrodes. The metal halide filling consists of thallous iodide, stannous iodide, and calcium iodide, with the stannous iodide enhancing the emission of calcium iodide while limiting the generation of continuous tin emission. The resulting discharge emits concentrated wavelengths in the visible spectrum, providing good efficiency and excellent color appearance for illuminated objects.
Another significant patent by Chen is a method and apparatus for expressing the relative brightness of artificial illumination. This invention measures illumination by extracting narrow bands of blue, green, yellow, and red-orange light. It generates signals based on the energy in these bands, which are then combined to express a number indicative of the relative brightness as perceived by the average observer.
