Download or read book Color Science and Photometry for Lighting with LEDs and Semiconductor Nanocrystals written by Talha Erdem and published by Springer. This book was released on 2019-01-18 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the application of semiconductor nanocrystals also known as colloidal quantum dots (QDs) to LED lighting for indoors and outdoors as well as LED backlighting in displays, summarizing the color science of QDs for lighting and displays and presenting recent developments in QD-integrated LEDs and display research. By employing QDs in color-conversion LEDs, it is possible to simultaneously accomplish successful color rendition of the illuminated objects and a good spectral overlap between the emission spectrum of the light source and the sensitivity of the human eye at a warm white color temperature – something that is fundamentally challenging to achieve with conventional sources, such as incandescent and fluorescent lamps, and phosphor-based LEDs.

Download or read book Light The Shape of Space written by Lou Michel and published by John Wiley & Sons. This book was released on 1995-10-27 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light: The Shape of Space Designing with Space and Light Lou Michel Every design professional who touches a space shapes the light and the feeling of that space. Architect, lighting engineer, interior designer, lighting or home furnishing manufacturer: each contributes an aesthetic layer, sometimes yielding unexpected results. All too often the best laid plans of one professional are unintentionally subverted by another. Removing surprises and guess work from design, Lou Michel, honored architectural lighting educator, has created Light: The Shape of Space, showing how to design with the effects of light rather than light itself. The book is a revolutionary resource for all design professionals and manufacturers of surfacing materials. Drawing on over fifteen years’ experience of research and teaching in the architectural Space and Light Laboratory at The University of Kansas, Michel masterfully examines the interrelationship of lighting and the design of architectural space as perceived not in architectural photos or paint chips and fabric swatches, but by human vision — the gateway to emotional response. The book was written for professionals who care about how people feel in the spaces they design, and focuses on the humanization of architecture. Taking a non-stylistic approach to design, Michel analyzes architecture from the perspective of how the users see their surroundings as they move through space. The reader will learn what pleases and what disturbs people based on how the human visual system responds to color, texture, pattern, and brightness. The book features principles of design for the student and professional, and is generously supported by illustrations and research. Michel also provides a method for evaluating the visual effectiveness of building materials and lighting systems, including those that will appear on the market long after this book is dog-eared. Michel unveils a groundbreaking luminance brightness rating system (LBR) and a nine-zone brightness scale to aid designers in previsualizing the appearance of surfacing materials at every stage of the design process, from schematics to development to refinement. Among the topics treated are: the interaction of lighting and spatial design color theory for space and light the luminance relationships between free-standing objects and the surrounding spatial boundaries against which they are seen the appearance of building materials in color and brightness when modified by light and spatial location lighting spatial connections, including the perception of rooms adjacent to the observer lighting and perception of spaces screened by architectural grilles creating lighted space Designing with the effects of light is both an art and a science. No other book on the market bridges that gap as successfully as Light: The Shape of Space.

Download or read book Sustainable Indoor Lighting written by Paola Sansoni and published by Springer. This book was released on 2014-12-29 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Encompassing a thorough survey of the lighting techniques applied to internal illumination characterized by high efficiency, optimized color and architectural integration, a consolidated summary of the latest scientific, technical and architectural research is presented in order to give the reader an overview of the different themes with their interactions and mutual effects. This book describes light principles, methodologies and realisations for indoor illumination at low consumption. Power efficiency, color characteristics and architectural aspects are analyzed in terms of their practical application, with the interactions between scientific, technological and architectural features considered in order to supply a complete overview, which can be read both at technical level and at user level. Introducing photometric and radiometric quantities and laws, the book first discusses tests and measurements assessing lighting and color characteristics before examining in detail artificial light sources with particular attention paid to measures to reduce consumption and optimize efficiency. Key sources are illustrated with producers and suppliers with technical details and use specifications included. Serving to maximize reader insights into the use of sunlight – considering light transfer, application to indoor illumination and in particular to museum lighting – in the color rendering properties of light sources and the architectural aspects for natural indoor lighting, the final part of this boo collects other related but important elements including architectural issues, environmental integration and the possibility of changing the light color by introducing suitable coatings. The physiological effects of internal illumination quality on user comfort is discussed and several possibilities for energy saving using domotics are outlined.

This book was released on 2014-08-08 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: The integrated and advanced science research topic man-machine-environment system engineering (MMESE) was first established in China by Professor Shengzhao Long in 1981, with direct support from one of the greatest modern Chinese scientists, Xuesen Qian. In a letter to Shengzhao Long from October 22nd, 1993, Xuesen Qian wrote: “You have created a very important modern science and technology in China!” MMESE primarily focuses on the relationship between man, machines and the environment, studying the optimum combination of man-machine-environment systems. In this system, “man” refers to people in the workplace (e.g. operators, decision-makers); “ machine” is the general name for any object controlled by man (including tools, machinery, computers, systems and technologies), and “environment” describes the specific working conditions under which man and machine interact (e.g. temperature, noise, vibration, hazardous gases etc.). The three goals of optimization of man-machine-environment systems are to ensure safety, efficiency and economy. Proceedings of the 14th International Conference on Man-Machine-Environment System Engineering are an academic showcase of the best papers selected from more than 400 submissions, introducing readers to the top research topics and the latest developmental trends in the theory and application of MMESE. These proceedings are interdisciplinary studies on the concepts and methods of physiology, psychology, system engineering, computer science, environment science, management, education, and other related disciplines. Researchers and professionals working in these interdisciplinary fields and researchers on MMESE related topics will benefit from these proceedings.
