Available in PDF, EPUB and Kindle. Book excerpt: Light Emitting Diodes (LEDs) are no longer confined to use in commercial signage and have now moved firmly, and with unquestioned advantages, into the field of commercial and domestic lighting. This development was prompted in the late 1980s by the invention of the blue LED, a wavelength that had previously been missing from the available LED spectrum and which opened the way to providing white light. Since that point, LED performance (including energy efficiency) has improved dramatically, and now compares with the performance of fluorescent lights - and there remain further performance improvements yet to be delivered. The book begins with the principles of LED lighting, then focuses on issues and challenges. Chapters are devoted to key steps in LED manufacturing: substrate, epitaxy, process and packaging. Photoelectric characterization of LEDs, Lighting with LEDs and the imposition of a certain level of color quality, are the subject of later chapters, and finally there is a detailed discussion of the emergence of OLEDs, or organic LEDs, which have specific capabilities of immediate interest and importance in this field.

Available in PDF, EPUB and Kindle. Book excerpt: Since the first light-emitting diode (LED) was invented by Holonyak and Bevacqua in 1962, LEDs have made remarkable progress in the past few decades with the rapid development of epitaxy growth, chip design and manufacture, packaging structure, processes, and packaging materials. LEDs have superior characteristics such as high efficiency, small size, long life, low power consumption, and high reliability. The market for white LED is growing rapidly in various applications. It has been widely accepted that white LEDs will be the fourth illumination source to substitute the incandescent, fluorescent, and high-pressure sodium lamps. With the development of LED chip and packaging technologies, the efficiency of high power white LED will broaden the application markets of LEDs while changing the lighting concepts of our lives. In LED Packaging for Lighting Applications, Professors Liu and Luo cover the full spectrum of design, manufacturing, and testing. Many concepts are proposed for the first time, and readers will benefit from the concurrent engineering and co-design approaches to advanced engineering design of LED products. One of the only books to cover LEDs from package design to manufacturing to testing Focuses on the design of LED packaging and its applications such as road lights Includes design methods and experiences necessary for LED engineers, especially optical and thermal design Introduces novel LED packaging structures and manufacturing processes, such as ASLP Covers reliability considerations, the most challenging problem for the LED industry Provides measurement and testing standards, which are critical for LED development, for both LED and LED fixtures Codes and demonstrations available from the book’s Companion Website This book is ideal for practicing engineers working in design or packaging at LED companies and graduate students preparing for work in industry. This book also provides a helpful introduction for advanced undergraduates, graduates, researchers, lighting designers, and product managers interested in the fundamentals of LED design and production.

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.

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: LED Lighting is a self-contained and introductory-level book featuring a blend of theory and applications that thoroughly covers this important interdisciplinary area. Building on the underlying fields of optics, photonics, and vision science, it comprises four parts. PART I is devoted to fundamentals. The behavior of light is described in terms of rays, waves, and photons. Each of these approaches is best suited to a particular set of applications. The properties of blackbody radiation, thermal light, and incandescent light are derived and explained. The essentials of semiconductor physics are set forth, including the operation of junctions and heterojunctions, quantum wells and quantum dots, and organic and perovskite semiconductors. PART II deals with the generation of light in semiconductors, and details the operation and properties of III-V semiconductor devices (MQWLEDs and μLEDs), quantum-dot devices (QLEDs & WOLEDs), organic semiconductor devices (OLEDs, SMOLEDs, PLEDs, & WOLEDs), and perovskite devices (PeLEDs, PPeLEDs, QPeLEDs, & PeWLEDs). PART III focuses on vision and the perception of color, as well as on colorimetry. It delineates radiometric and photometric quantities as well as efficacy and efficiency measures. It relays the significance of metrics often encountered in LED lighting, including the color rendering index (CRI), color temperature (CT), correlated color temperature (CCT), and chromaticity diagram. PART IV is devoted to LED lighting, focusing on its history and salutary features, and on how this modern form of illumination is deployed. It describes the principal components used in LED lighting, including white phosphor-conversion LEDs, chip-on-board (COB) devices, color-mixing LEDs, hybrid devices, LED filaments, retrofit LED lamps, LED luminaires, and OLED light panels. It concludes with a discussion of smart lighting and connected lighting. Each chapter contains highlighted equations, color-coded figures, practical examples, and reading lists.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This book explores how lighting systems based on LED sources have the ability to positively influence the human circadian system, with benefits for health and well-being. The opening chapters examine the functioning of the human circadian system, its response to artificial lighting, potential health impacts of different types of light exposure, and current researches in circadian photometry. A first case study analyzes the natural lighting available in an urban interior, concluding that it is unable to activate the human circadian system over the entire year. Important original research is then described in which systems suitable for artificial circadian lighting in residential interiors and offices were developed after testing of new design paradigms based on LED sources. Readers will also find a detailed analysis of the LED products available or under development globally that may contribute to optimal artificial circadian lighting, as well as the environmental sensors, control interfaces, and monitoring systems suitable for integration with new LED lighting systems. Finally, guidelines for circadian lighting design are proposed, with identification of key requirements.
