Available in PDF, EPUB and Kindle. Book excerpt: What kind of people does it take to change the light bulb? That is the question Bob Johnstone addresses in this follow-up to Brilliant!, his critically acclaimed book on the origins of the LED revolution. The answer is passionate individuals determined to make the world a better - and better-lit - place. The book tells the story of what has been called "one of the fastest technology shifts in human history." It is a shift that affects us all. Lighting accounts for up to twenty percent of the electricity we consume. LEDs use much less electricity than incandescent light bulbs, leading to huge reductions in our energy consumption, and helping to slow down climate change. But the LED revolution also encompasses light for better health and year-round crops, as well new, previously undreamed-of applications.

Book excerpt: The book is organized in four chapters. Chapter 1 deals with an introduction to light and lighting. As a power electronics engineer working on LEDs and lighting systems in general, I think it is important for the reader to have the basic knowledge about lighting systems, which I have tried to summarize in this chapter. Because of the extremely interesting possibilities of LEDs to generate different light colors, Chapter 1 includes a section related to the understanding of color quantification and measurement in different color spaces. The Chapter also includes several examples on light and color calculations.In order to develop and implement a suitable LED driver, it is necessary to have a good knowledge about LED behavior and characteristics. Thus, Chapter 2 aims at providing the reader with the most important issues related to LED operation and modeling from a practical point of view. The most common LED structures and materials are presented in this chapter together with the most relevant electrical, thermal and optical characteristics, making special emphasis on those characteristics provided by LED manufacturers in their datasheets. Special sections are dedicated to light dimming and color mixing. The chapter is closed with a brief review of organic LED (OLED) technology, which is another promising LED technology nowadays.Chapter 3 is devoted to DC LED drivers, which are those LED drivers intended to supply the LED from a DC voltage source, like a battery or a DC bus. This chapter covers the three most relevant technologies that are being used to implement DC LED drivers at the present time, which are those based on linear regulators, switched capacitor regulators and switching regulators. The most relevant solutions to implement DC LED drivers are reviewed from a practical point of view. The chapter also reviews the most common control methods applied to DC LED drivers. Examples are included by means of computer simulations based on LTspice, which is a free but powerful SPICE-based simulation software developed by former Linear Technologies Company, now part of Analog Devices. The chapter ends with a section devoted to LED configurations, namely, series, parallel and matrix configurations, which are employed to implement high-power LED lamps.Finally, Chapter 4 is dedicated to off-line LED drivers. This is the denomination given to LED drivers that are intended to operate from an AC grid voltage. These are the most complicated LED drivers since they usually require the implementation of a front-end power-factor-correction (PFC) stage followed by a downstream DC-DC converter to adapt voltage levels and provide regulated current to the LED lamp. The most important standards and regulations related to this type of LED drivers are presented at the beginning of the chapter. Then, single-stage LED drivers are studied, which can be used as a stand-alone off-line LED driver or as a first stage in a two-stage off-line LED driver. The highly-relevant problem of requiring a large storage capacitance in single-stage off-line LED drivers to cope with the double-line-frequency pulsating power originated from line voltage rectification is addressed in this chapter. Finally, integrated two-stage off-line LED drivers are presented and studied as a solution to reduce the storage capacitance of off-line LED drivers, aiming at using high-reliability film-capacitors instead of less reliable electrolytic capacitors. LTspice simulation examples are also provided in this chapter to allow the reader to have a better idea about the design and operation of this type of LED drivers.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Color & Light is an essential practical guide to how color works in light. Written from the perspective of a theatrical lighting designer, it discusses how to see color, how to construct effective lighting palettes, and how to make use of both color filters and color-mixing LED fixtures to create compositions that work well with scenery and costumes to tell compelling stories. We are presently at the leading edge of a revolution in theatrical lighting, redefining how it can be used to create and communicate. Today's LED-based additive color-mixing fixtures require new methodologies and new ways of thinking, and Color & Light directly addresses this technology's potentials and challenges. But underpinning lighting's many recent technological changes is the fundamental language of color that artists have worked with since the birth of humanity's artistic urges.
