Lighting Engineering Applied Calculations

'Lighting Engineering: Applied Calculations' describes the mathematical background to the calculation techniques used in lighting engineering and links them to the applications with which they are used. The fundamentals of flux and illuminance, colour, measurement and optical design are covered in detail. There are detailed discussions of specific applications, including interior lighting, road lighting, tunnel lighting, floodlighting and emergency lighting. The authors have used their years of experience to provide guidance for common mistakes and useful techniques including worked examples and case studies. The last decade has seen the universal application of personal computers to lighting engineering on a day-to-day basis. Many calculations that were previously impracticable are therefore now easily accessible to any engineer or designer who has access to an appropriate computer program. However, a grasp of the underlying calculation principles is still necessary in order to utilise these technologies to the full. Written by two of the leading authorities on this subject, 'Lighting Engineering' is essential reading for practising lighting engineers, designers and architects, and students in the field of lighting.

This comprehensive reference provides a practical, fully illustrated guide to design, specification, and application of state-of-the-art lighting, from the fundamentals of illumination to hands-on application. The full scope of light sources is examined and basic design methods for both indoor and outdoor lighting are presented, along with optimum application strategies for merchandise, offices, industrial settings, floodlighting, parking lots and street lighting. The second edition features a new chapter on skylights for industrial buildings, covering layout parameters and daylight availability calculations used to predict skylight performance. The chapter on lighting retrofits has been revised to emphasize methods for analyzing potential retrofits, examining how retrofit results can be predicted, how to evaluate retrofit proposals, and how to avoid common mistakes. Lighting maintenance, as well as the economics of lighting design, including life cycle cost analysis, are also covered.

International Series of Monographs in Electrical Engineering, Volume 1: Lighting Fittings Performance and Design details the advances in the design and prediction of the performance of lighting fittings. The title first covers luminous intensity and flux, and then proceeds to tackling illumination from line and area sources. Next, the selection deals with the direct flux, interreflections, and optical design. The text also deals with the application of the principles of optical design, along with the mechanical, thermal, and electrical design and testing. The seventh chapter discusses photometric measurements, while the eighth chapter covers the applied lighting calculations. The book will be of great use to designers, lighting engineers, and photometricians.

Conservation scientists in museums and galleries have a clear understanding of the damage that light can inflict on an object, but what of the designers that create exhibitions to display these precious items? Light for Arts Sake provides a basis for a level of professional expertise for lighting practice in museums. Rather than portraying conservation and display as having diametrically opposed objectives, the central concept is that the interaction of light and art media is the source for both the visual experience and the degradation of the artwork. Optimal solutions derive from understanding and controlling the interaction process, and the need is for the level of understanding among lighting professionals to be brought closer to that found among conservation scientists.

This book describes active illumination techniques in computer vision. We can classify computer vision techniques into two classes: passive and active techniques. Passive techniques observe the scene statically and analyse it as is. Active techniques give the scene some actions and try to facilitate the analysis. In particular, active illumination techniques project specific light, for which the characteristics are known beforehand, to a target scene to enable stable and accurate analysis of the scene. Traditional passive techniques have a fundamental limitation. The external world surrounding us is three-dimensional; the image projected on a retina or an imaging device is two-dimensional. That is, reduction of one dimension has occurred. Active illumination techniques compensate for the dimensional reduction by actively controlling the illumination. The demand for reliable vision sensors is rapidly increasing in many application areas, such as robotics and medical image analysis. This book explains this new endeavour to explore the augmentation of reduced dimensions in computer vision. This book consists of three parts: basic concepts, techniques, and applications. The first part explains the basic concepts for understanding active illumination techniques. In particular, the basic concepts of optics are explained so that researchers and engineers outside the field can understand the later chapters. The second part explains currently available active illumination techniques, covering many techniques developed by the authors. The final part shows how such active illumination techniques can be applied to various domains, describing the issue to be overcome by active illumination techniques and the advantages of using these techniques. This book is primarily aimed at 4th year undergraduate and 1st year graduate students, and will also help engineers from fields beyond computer vision to use active illumination techniques. Additionally, the book is suitable as course material for technical seminars.
