This book is a comprehensive guide to the theory and practice of lighting. Covering the physics of light production, light sources, circuits and a wide variety of lighting applications, it is both suitable as a detailed textbook and as thoroughly practical guide for practising lighting engineers. This fourth edition of Lamps and Lighting has been completely updated with new chapters on the latest lamp technology and applications. The editors ahve called upon a wide range of expertise and as a result many sections have been broadened to include both European and US practice. The book begins with a description of the fundamentals of light, vision, colour and measurement. Part II, the main section of the book, deals with lamps and control equipment and includes descriptions of all lamp types in use today. Part III on lighting covers both interior and exterior applications.

A comprehensive guide to the therapeutic benefits of light and color and how they affect our physical and psychological well-being • Shares scientific research on how different wavelengths of light influence our cells, brain function, sleep patterns, and emotional stability • Examines several forms of light therapy, including chromotherapy, heliotherapy, actinotherapy, and thermotherapy • Explains how to use light and color therapy, maximize the benefits of sunlight, and avoid the health risks of new light sources such as compact fluorescents and LEDs Beginning with sun worship in prehistory and sunshine therapies in ancient Egypt, Greece, and India, light has long been associated with the sublime, the divine, and healing. Yet only recently have we begun to understand how different parts of the light spectrum, from infrared to ultraviolet, can affect our physical and psychological well-being. Covering the historic, scientific, and spiritual aspects of light and its role in energy medicine, Anadi Martel explores the vibrational nature of light and the interaction between light, biology, and consciousness. He demonstrates light’s incredible effects on the physical, energetic, and cognitive dimensions of life and examines several forms of light therapy, including chromotherapy (color therapy), heliotherapy (sun therapy), actinotherapy (ultraviolet therapy), and thermotherapy (infrared therapy). He details how to use light therapy daily, get optimal benefits from sunlight, and avoid the health risks of new artificial lighting such as compact fluorescents and LEDs. Combining his own 30 years of research with practical insight from the many phototherapy pioneers he’s encountered, the author examines scientific studies on how specific wavelengths of light influence our cells and DNA, brain function, sleep patterns, and emotional stability; speed the healing of wounds; and are effective in the treatment of disease, including arthritis, stroke, Alzheimer’s, Parkinson’s, and brain and nerve injuries. Exploring the spiritual aspects of light, the author explains why auras and halos have been used to represent sages and saints of all traditions, revealing the intimate link between light and consciousness. Investigating the many laser, monochrome, audiovisual, and infrared machines designed to heal disease and treat emotional disorders, Martel also reveals promising medical applications for light that are currently in development, inviting the reader not only to appreciate the complexities of light but to maximize its therapeutic dimensions.
