We’re on the brink of a lighting revolution with light-emitting diodes—the tiny LEDs you’ve seen in electronic devices for years. With this practical guide, you’ll go behind the scenes to see how and why manufacturers are now designing LED devices to light everything from homes and offices to streets and warehouses. Author Sal Cangeloso shows you the working parts of a “simple” LED bulb and explains the challenges electronics companies face as they push LED lighting into the mainstream. You’ll learn how you can use LEDs now, and why solid state lighting will bring dramatic changes in the near future. Explore the drivers, phosphors, and integrated circuits in a typical LED bulb Understand the challenges in producing LED bulbs with acceptable brightness, color temperature, and power consumption Learn about non-bulb LED applications, including lamps, street lights, and signage Discover the market forces driving—and impeding—the adoption of LED lighting Compare LEDs to compact fluorescent lamps (CFLs) and electron-stimulated luminescence (ESL) bulbs Gaze into the future of intelligent lighting, including networked lighting systems

Too many companies are managed not by leaders, but by mere role players and faceless bureaucrats. What does it take to be a real leader—one who is confident in who she is and what she stands for, and who truly inspires people to achieve extraordinary results? Rob Goffee and Gareth Jones argue that leaders don’t become great by aspiring to a list of universal character traits. Rather, effective leaders are authentic: they deploy individual strengths to engage followers’ hearts, minds, and souls. They are skillful at consistently being themselves, even as they alter their behaviors to respond effectively in changing contexts. In this lively and practical book, Goffee and Jones draw from extensive research to reveal how to hone and deploy one’s unique leadership assets while managing the inherent tensions at the heart of successful leadership: showing emotion and withholding it, getting close to followers while keeping distance, and maintaining individuality while “conforming enough.” Underscoring the social nature of leadership, the book also explores how leaders can remain attuned to the needs and expectations of followers. Why Should Anyone Be Led By You? will forever change how we view, develop, and practice the art of leadership, wherever we live and work.

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.

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.
