A Novel Light Source Based on a RF-Driven High Intensity Discharge Plasma

January 6, 2009 - 12:00pm

Almost all the lighting news recently has been about advances in LED (Light Emitting Diode) lighting. But several companies are quietly developing new light sources that are based rather on improving the efficiency and longevity of “conventional” light sources, such as High Intensity Discharge (HID) lamps. Luxim Corporation, a Sunnyvale-based lighting technology company, has developed a Solid-State Plasma Light Source, LIFI, for street, architectural, and general area lighting applications. The LIFI platform is a fully encapsulated, electrodeless quartz vessel coupled to a resonator that is driven by a solid-state RF amplifier. This approach provides many benefits over traditional arc sources, LEDs, and other electrodeless technologies. LIFI combines the reliability and controls of solid-state devices with the full-spectrum and high output of an HID bulb. A single LIFI source produces 22,000 lumens with 120 L/W lamp efficacy and has lifetimes of 30,000 hrs. These features, combined with its directional and compact form factor, are driving innovative fixture designs and up to 2x higher fixture efficiencies. In this seminar, representatives of Luxim will provide a demonstration of the technology behind LIFI, discuss application case studies that harness all of LIFI’s benefits, and review synergies with energy-efficiency activities at LBNL.
