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.

Download or read book The Heart Led Leader written by Tommy Spaulding and published by Crown Currency. This book was released on 2015-10-06 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: New York Times bestselling author Tommy Spaulding shows you how looking inwards--and leading with your heart--can transform your life. In his New York Times bestseller, It’s Not Just Who You Know, world renowned leadership speaker and former CEO of Up with People Tommy Spaulding talked about the power of building genuine and lasting relationships both personally and professionally. In The Heart-Led Leader, Spaulding turns his focus to ourselves--to who we are. Authentic leaders, Spaulding says, live and lead from the heart. The values and principles that guide our lives and shape our ability to lead others is far more important than our title, or our ability to crunch numbers, or the impressive degrees we display on our walls. To effect true transformational change, heart-led leaders draw on the qualities of humility, vulnerability, transparency, empathy and love. Illustrated with stories from his own life, and from some of the exceptional leaders he has met and worked with over the years, Spaulding unpacks what those qualities mean, talks about the 18-inch journey from the head to the heart--from our intellect to our emotions--and shows us how to incorporate them into our careers, into how we manage and lead others, and into how we live our lives. It is a vision of leadership that has the power to transform everything we do, and the lives of everyone we touch.

Download or read book Power Supplies for LED Driving written by Steve Winder and published by Newnes. This book was released on 2016-12-28 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power Supplies for LED Driving, Second Edition explores the wide use of light-emitting diodes due to their efficient use of power. The applications for power LEDs include traffic lights, street lamps, automotive lighting, architectural lights, theatre lighting, household light replacements, signage lighting (replacing neon strip lights and fluorescent tubes), LCD display backlighting, and many more. Powering (driving) these LED's is not always simple. Linear driving is inefficient and generates far too much heat. With a switching supply, the main issues are EMI, efficiency, and of course cost. This book covers the design trade-offs involved in LED driving applications, from low-power, to UB-LEDs and beyond. - Provides a practical, hands-on approach to power supply design for LED drivers - Contains detailed examples of what works throughout the design process - Presents commentary on how the calculated component value compares with the actual value used, including a description of why the choice was made

Download or read book L e d written by Bob Johnstone and published by Createspace Independent Publishing Platform. This book was released on 2017-05-19 with total page 334 pages. 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.

Download or read book How Ike Led written by Susan Eisenhower and published by Macmillan + ORM. This book was released on 2020-08-11 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: How Dwight D. Eisenhower led America through a transformational time—by a DC policy strategist, security expert and his granddaughter. Few people have made decisions as momentous as Eisenhower, nor has one person had to make such a varied range of them. From D-Day to Little Rock, from the Korean War to Cold War crises, from the Red Scare to the Missile Gap controversies, Ike was able to give our country eight years of peace and prosperity by relying on a core set of principles. These were informed by his heritage and upbringing, as well as his strong character and his personal discipline, but he also avoided making himself the center of things. He was a man of judgment, and steadying force. He sought national unity, by pursuing a course he called the "Middle Way" that tried to make winners on both sides of any issue. Ike was a strategic, not an operational leader, who relied on a rigorous pursuit of the facts for decision-making. His talent for envisioning a whole, especially in the context of the long game, and his ability to see causes and various consequences, explains his success as Allied Commander and as President. After making a decision, he made himself accountable for it, recognizing that personal responsibility is the bedrock of sound principles. Susan Eisenhower's How Ike Led shows us not just what a great American did, but why—and what we can learn from him today.
