Latest Patents

One of his latest patents is the "Pulsed Alkali Metal Vapor Discharge Lamp with Ceramics Outer Envelope." This innovative lamp operates in a pulsed mode and features an inner envelope made of first ceramics and an outer envelope made of second ceramics. The design allows for the inner envelope, which contains cesium, mercury, and a rare gas, to be enclosed under a vacuum or inert atmosphere. The vapor pressure of cesium is specifically selected to range from 400 to 1000 Torr, while the outer envelope is made of alumina ceramics.

Another significant patent is the "Metal Vapor Discharge Lamp." This lamp operates using high voltage generated by a heat-sensitive switch in an outer bulb. It is designed to maintain a relatively low pressure of sealed gas or mercury in the outer bulb, which helps control the surge voltage and prevents insulation breakdown of the ballast and operation circuit.
