History of Remote Phosphor

Thomas Edison files for U.S. Patent 865,367 for a lamp using X-Rays to excite phosphor.

Together with Friedrich Meyer and Hans Spanner, Edmund Germer patented an experimental fluorescent lamp.

General Electric Company offers the first commercial fluorescent lamps, using ultraviolet light in a vacuum tube to excite phosphor on glass and create visible light.

Artist Andy Warhol's painting 'Day-Glow Flowers' utilizes the surreal colors of phosphor paint.

Automotive vehicle displays move digital, utilizing phosphors applied remotely to create a more technologically advanced looking dash.

Philips introduces Fortimo remote phosphor module at Lightfair International 2008, validating the remote phosphor technology Intematix had been developing for years.

Karl Ferdinand Braun, a German physicist, invents cathode-ray tube using an electron gun firing through a phosphor-coated screen.

Robert and Joseph Switzer find some organic materials glow under black lights. They turn these materials into phosphor inks, inventing Day-Glo.

One million homes in the United States have television sets powered by cathode-ray tubes.

Narrow-band phosphors allow mixing for improved performance.

Intematix begins commerical sale of phosphor and begins commercialization efforts in applying that phosphor in remote systems for LED lighting.

Academic discussion of remote phosphor applications for LEDs includes "Improved performance of white LEDs" by Nadarajah Narendran, Ph.D. from SPIE Fifth International Conference on Solid State Lighting.

Intematix introduces ChromaLit™ remote phosphor light sources. Based on Intematix' patented technology and many years of research and development, ChromaLit is the first independently available remote phosphor light source.
