Revolution in Lamps: A Chronicle of 50 Years of Progress, 2nd Edition

Text for designers, engineers, architects and others interested in lamp and lighting technology, educating readers about various light sources, their function and development, parts of their history, and the author's thoughts about the future of each lamp type. These include circuitry, ballasts, electrodeless lamps, and LEDs.

Annotation. Written for designers, engineers, architects and others involved with application of modern lamps and lighting systems, this book provides a comprehensive accounting of current lamp technologies, covering both the fundamental technologies on which they are based and trends in their use, both historical and current. You'll learn about how recent innovations such as those involving LEDs, electrodeless lamps, ballasts and circuitry are continuing to improve lamp efficacy, as well as how specialized lamp requirements have fostered development of special-purpose lighting, such as for non-visual, for health, and for high performance applications. The full spectrum of current lamp technologies are examined in clear, non-technical language with ample illustration Not changing fashions in shades and bases, nor such phenomena as lava lights, but the electronic and physical design of various light sources is the concern of the engineers here. For designers, engineers, architects, and general readers with some background in science, they look at developments since the end of world War II in the potassium secret behind modern tungsten wire production, the T3 quartz infrared lamp, the tungsten halogen lamp, lamp phosphors, the ballast, fluorescent lamps, mercury and metal halide lamps, and the high pressure sodium lamp. No date is mentioned for the first edition. Annotation copyrighted by Book News, Inc., Portland, OR Thomas Alva Edison did not invent the incandescent lamp-he commercialized it.
