Title: Innovations of Hongyan Gu in High Efficacy Lighting
Introduction
Hongyan Gu is an accomplished inventor based in Lexington, MA (US). He has made significant contributions to the field of lighting technology, particularly with his innovative designs that enhance the efficiency and quality of light sources.
Latest Patents
Hongyan Gu holds a patent for a "High efficacy pulsed, dimmable high pressure cesium lamp." This dimmable electrical discharge lamp provides radiation with a Color Rendering Index (CRI) of over 90 and a color temperature ranging between about 3000-4000° K, even when dimmed by up to 40% of its rated power. The lamp features a fill of a mixture of cesium, mercury, and a rare gas, all enclosed in a hermetically sealed polycrystalline alumina arc tube. This arc tube contains an electrode at each end and is further protected by an outer jacket. The lamp is equipped with a circuit that supplies current to the arc tube, utilizing a low-frequency wave simmer current along with one or more current pulses superimposed on the simmer current. The design ensures a short gradient of the leading edge of the pulse, generating a high electrical field that promotes a high degree of ionization of the cesium.
