Promoting the design, application and evaluation of visually and electrically effective LED light sources and luminaires for general indoor lighting as well as outdoor and vehicle lighting, this book combines the knowledge of LED lighting technology with human perceptual aspects for lighting scientists and engineers. After an introduction to the human visual system and current radiometry, photometry and color science, the basics of LED chip and phosphor technology are described followed by specific issues of LED radiometry and the optical, thermal and electric modeling of LEDs. This is supplemented by the relevant practical issues of pulsed LEDs, remote phosphor LEDs and the aging of LED light sources. Relevant human visual aspects closely related to LED technology are described in detail for the photopic and the mesopic range of vision, including color rendering, binning, whiteness, Circadian issues, as well as flicker perception, brightness, visual performance, conspicuity and disability glare. The topic of LED luminaires is discussed in a separate chapter, including retrofit LED lamps, LED-based road and street luminaires and LED luminaires for museum and school lighting. Specific sections are devoted to the modularity of LED luminaires, their aging and the planning and evaluation methods of new LED installations. The whole is rounded off by a summary and a look towards future developments.

The Handbook of Advanced Lighting Technology is a major reference work on the subject of light source science and technology, with particular focus on solid-state light sources – LEDs and OLEDs – and the development of 'smart' or 'intelligent' lighting systems; and the integration of advanced light sources, sensors, and adaptive control architectures to provide tailored illumination which is 'fit to purpose.' The concept of smart lighting goes hand-in-hand with the development of solid-state light sources, which offer levels of control not previously available with conventional lighting systems. This has impact not only at the scale of the individual user, but also at an environmental and wider economic level. These advances have enabled and motivated significant research activity on the human factors of lighting, particularly related to the impact of lighting on healthcare and education, and the Handbook provides detailed reviews of work in these areas. The potential applications for smart lighting span the entire spectrum of technology, from domestic and commercial lighting, to breakthroughs in biotechnology, transportation, and light-based wireless communication. Whilst most current research globally is in the field of solid-state lighting, there is renewed interest in the development of conventional and non-conventional light sources for specific applications. This Handbook comprehensively reviews the basic physical principles and device technologies behind all light source types and includes discussion of the state-of-the-art. The book essentially breaks down into five major sections: Section 1: The physics, materials, and device technology of established, conventional, and emerging light sources, Section 2: The science and technology of solid-state (LED and OLED) light sources, Section 3: Driving, sensing and control, and the integration of these different technologies under the concept of smart lighting, Section 4: Human factors and applications, Section 5: Environmental and economic factors and implications

People have always wanted light, and until the nineteenth century the only useful source of light was flame. Electricity brought clean light without flame, and sometimes even without much heat. This book is about the ways in which people have made light to lengthen their day. It explains howoil lamps, candles, and gas lights work and, drawing on writings of the time, shows how the available lights affected daily life. The principles of all the main types of electric lights now available are described. Alongside this technical history, quotations from Aristophanes to Jane Austen, fromJames Boswell to Kenneth Grahame, illustrate the social importance of lighting.

Anyone working with lighting in the entertainment industries will find this an immensely readable source of information. The authors, themselves experienced lighting practitioners, have collected a wealth of essential lighting technology and data into one comprehensive reference volume in an accessible, jargon-free style. The new edition of this popular text covers the very latest technology, including advances in lamps, motorised lights, dimmers and control systems and current safety regulations.

Recent improvements in LED technology have made them as ubiquitous as cell phones. In fact, LEDs light up almost all cell phones screens. The technology's myriad applications and low energy use have made it nearly impossible to get through daily chores without coming in contact with LEDs. Probable advances include increased ability of the technology to support more efficient lighting and enhanced communications. With balanced coverage of the basics and future developments, Introduction to Light Emitting Diode Technology and Applications takes you on a tour of the LED evolution. The book begins with a brief history of the effort to enable the device that generates light through modern organic LEDs and reviews the fundamentals and principles of light prior to a detailed explanation of how LEDs generate different colors. After forming this basic foundation, the book examines the key LEDs in lighting and communications. It then discusses the latest opportunities and advancements in high brightness (HB) LED technology, solid state lighting, and handheld electronic applications. As we approach a new decade the role of LEDs is literally set to explode, with organic light emitting diodes emerging as a leading next generation technology for electronic displays and lighting. Challenges still exist, including light extraction, luminosity, and white light generation, not to mention non-technical obstacles such as IP disputes and the lack of standards. This book provides a foundation for resolving these issues and developing new applications for LEDs in the promising general illumination market.

Published to celebrate the awarding of the 2014 Nobel Prize in physics to Shuji Nakumura, this newly revised edition of a 2007 book profiles the gifted Japanese engineer who is largely responsible for the coming revolution in lighting technology. He came out of nowhere to stun the world with his announcement that he had created the last piece in the puzzle needed for manufacturing solid-state white lights. The invention of this holy-grail product, which promises to make Edison's light bulb obsolete, had eluded the best minds at the top electronic firms for twenty-five years. Thanks to Nakamura's work, the technology of light emitting diodes (LEDs) is ready for widespread implementation. Its impacts will include a reduction in energy consumption for electric lighting by up to 80 percent. This revised edition contains a new preface and an afterword that summarizes Nakamura's most recent accomplishments. In 2008, he and two other scientists founded a company called Soraa (which means sky in Japanese). In 2012, the firm debuted a new technology, based on improved crystal growth (using a technique pioneered by Shuji). It enables second-generation LEDs that are much smaller, more energy-efficient, produce better color, and most likely will replace halogen lights. Besides the Nobel Prize, Nakamura is also the winner of the prestigious $1.5 million Millennium Technology Prize and Japan's Order of Culture Award. Veteran technology writer Bob Johnstone is the first Western journalist to meet and interview Nakamura and he has received the brilliant engineer's full cooperation through a series of exclusive interviews given for the book.

First published in 2005. Advanced Lighting Controls is edited by Craig DiLouie and written for engineers, architects, lighting designers, electrical contractors, distributors, and building owners and managers. Advanced lighting controls, indicated by research as the "next big thing," are now mandated by the ASHRAE/IES 91.1-1999 energy standard, the basis for all state energy codes in the U.S., and are becoming the norm rather than the exception in new construction. This book provides in-depth information about the major trends, technologies, codes, and design techniques shaping the use of today's lighting control systems, including dimming, automatic switching, and global as well as personal control.

Using case studies, such as the use of candlelight and energy saving lightbulbs in Denmark, this book unravels light’s place at the heart of social life. In contrast to common perception of light as a technical and aesthetic phenomenon, Mikkel Bille argues that there is a cultural and social logic to lighting practices. By empirically investigating the social role of lighting in people's everyday lives, Mikkel Bille reveals how and why people visually shape their homes. Moving beyond the impact of its use, Bille also comments on the politics of lighting to examine how ideas of pollution and home act as barriers for technological fixes to curb energy demand. Attitudes to these issues are reflective of how human perceptions and practices are central to the efforts to cope with climate change. This ethnographic study is a must-read for students of anthropology, cultural studies, human geography, sociology and design.
