Understanding LED Illumination - M. Nisa (iem Led Lighting Technologies Khan - Bog - Taylor & Francis Inc - Plusbog.dk

Understanding LED Illumination - M. Nisa (iem Led Lighting Technologies Khan - Bog - Taylor & Francis Inc - Plusbog.dk

Understanding LED Illumination elucidates the science of lighting for light emitting diodes. It presents concepts, theory, simulations, and new design techniques that shine the spotlight on illumination, energy efficiency, and reducing electrical power consumption. The text provides an introduction to the fundamentals of LED lamp design, and highlights the principles of large-space and 3D object illumination for developing competitive LED lamps. The first part of the book discusses lamp output metrics and characterization methods, while the second part of the book explores certain retail and prototype lamp comparisons with theory, simulations and experiments It details the light propagation and distribution characteristics of LED light sources for general illumination applications, and presents design and simulation requirements for LED lamps suited for real-world applications. It also addresses light generation, efficiency, theoretical limits, efficiency limiting factors, and LED lamp design elements. - - Emphasizes the lighting aspects for LED lamps: quality and improvement - - - Describes the basics of junction diode and the intricacies of compound semiconductor optoelectronic properties including the thermal, electrical, optical, and mechanical aspects - - - Explains the challenges of LED lighting in scientific and mathematical terms - - - Includes case studies from Osram Optosemiconductors, Sylvania, and Phillips, GE, and others - The book characterizes several LED replacement lamps for household and commercial lighting and discusses a novel design for improving tubular LED replacements. It takes the mysteries out of solid-state lighting for lighting designers, and helps LED scientists and engineers effectively design their products to provide high-quality illumination.

Cultural Foundations of Political Psychology - Paul Roazen - Bog - Taylor & Francis Inc - Plusbog.dk

Cultural Foundations of Political Psychology - Paul Roazen - Bog - Taylor & Francis Inc - Plusbog.dk

Over the centuries all of the great philosophers made psychology central to understanding social life. Indeed, the ancient Greeks thought it impossible to conceive of political life without insight into the human soul. Yet insuffficient professional legitimization attaches to the central importance of modern depth psychology in understanding politics. Cultural Foundations of Political Psychology explores the linkages between psychology and politics, focusing on how rival conceptions of the good life and unspoken moral purposes in the social sciences have led to sectarian intolerance. Roazen has always approached the history of psychoanalysis with the conviction that ethical issues are implicit in every clinical encounter. Thus, his opening chapter on Erich Fromm''s exclusion from the International Psychoanalytic Association touches on a host of political matters, including collaboration as opposed to resistance to Nazi tyranny. Roazen also brings a public/private perspective to such well-known episodes as the Hiss/Chambers case, the circumstances of Virginia Woolf''s madness and suicide, and the matter of CIA funding of the monthly Encounter . He deals with the reaction to psychoanalysis on the part of three major philosophers--Althusser, Wittgenstein, and Buber--and looks at the link between psychology and politics in the work of such political theorists as Machiavelli, Rousseau, Burke, Tocqueville, Berlin, and Arendt. A chapter grappling with Vietnam and the Cold War illustrates how political psychology should be concerned with questions of an ethical or "ought" character. In examining the social and psychological bases for political theorizing, Roazen shows how both psychology and politics must change and redefine their methodologies as a result of their interaction. Roazen concludes with a chapter on how political psychology must deal with issues posed by changing conceptions of femininity. This volume is a pioneering exploration of the intersection of psychology and politics.
