LED UPDATE 3) 4) 5) 6) 7) learn semiconductor lighting; it’s also a comprehensive resource for other relevant information. The supply chain for LED modules and luminaires. By providing detailed, thermal-simulation methods and results, the book describes the importance of integrated designs for LED-lamp modules that comprise various components, including heat sinks, electrical drive and secondary-optical elements. Comprehensive quantification and qualification methods for lamps. The book offers LED evaluation methods and terms in complete sync with lightingindustry norms. Lamp properties to suit major lighting applications. It explains the unique challenges LEDs face to meet the demands of many general lighting applications. The illumination challenges of LED lighting explained in scientific and mathematical terms with detailed optical simulations and a new theory. Readers can point to reasons why LED are directional and look harsh, and can also visualize why LEDs are naturally suited to illuminate planar surfaces such as signs. A new method to make LED illumination as beautiful as incandescent radiation, while also maintaining the energy-saving benefits of SSL (U.S. Patent 8,348,467 issued to me on January 8, 2013). Imagine the attractive possibility of having energy-efficient LED lamps that won’t blind us when we look at them. The book provides readers with a solid text on LED and other lighting technologies, so they can make good choices toward illuminating our environment. It’s a practical resource for readers involved in any aspect of lighting technology and provides the necessary background by connecting science, art and human psychology. Although certain features are comparable to Edison’s lightbulb, LED lighting is a new technology. It uses technologies similar to modern electronics, a relatively new technology that has changed the world dramatically by underlying communication technologies and gadgets that combine video, sound and interaction for all users – from anywhere in the world. Electronic technologies’ core elements also enable LED lighting. And, like any technology, LEDs involve hard science and engineering, and continuous advancements that ensure meaningful benefits and cost savings. “Understanding LED Illumination” offers the hope that we can light up the world better than ever before. It addresses lighting by combining science, art and human psychology – the same way light has touched us since the dawning of humankind. n LEDs look much better in uniform. Makrolon® LD polycarbonate sheets deliver uniform light diffusion for today’s LED signage. They feature an advanced light diffusion technology that provides excellent light uniformity. LED hot spots and shadowing are eliminated in ﬂat or formed applications. Makrolon LD is available in a range of standard sign colors and can be custom matched to industry colors. Don’t limit your design ﬂexibility with LEDs. Makrolon LD delivers now. Call 800-254-1707 for samples or visit www.shefﬁeldplastics.com to locate your local, authorized distributor.
