Visual and Non-Visual Effects of Light


Book Description

The introduction of artificial lighting extends the time of wakefulness after dark and enables work at night, thus disturbing the human circadian rhythm. The understanding of the physiological mechanisms of visual and non-visual systems may be important for the development and use of proper light infrastructure and light interventions for different workplace settings, especially for shift work conditions. Visual and Non-Visual Effects of Light: Working Environment and Well-Being presents the impact of lighting in the working environment on human health, well-being and visual performance. The physiological explanation of the visual and non-visual effects of light on humans which discusses the biological bases of image and non-image forming vision at the cellular level may be of particular interest to any professional in the field of medicine, physiology, and biology. It is one of the intentions of this book to put forward some recommendations and examples of lighting design which take into account both the visual and non-visual effects of light on humans. These may be of particular interest to any professional in the field of lighting, occupational safety and health, and interior design. "What effects on health can a light ‘overdose’ or light deficiency have? What is bad light? The authors of the monograph provide answers to these questions. Just as for a physicist, the dual nature of light comprises an electromagnetic wave and a photon, the duality of light for a physician comprises visual and non-visual effects." --------------------------------------------------------Prof Jacek Przybylski, Medical University of Warsaw "This is a unique publication in the field of lighting technology. The authors have skillfully combined both the technical and biomedical aspects involved, which is unprecedented in the literature available. As a result, an important study has been created for many professional groups, with a significant impact on the assessment of risks associated with LED sources." --------------------------------------------Prof Andrzej Zając, Military University of Technology, Warsaw

Human Factors in Lighting, Second Edition


Book Description

The availability of electric lighting has changed the lives of people the world over and lighting is a major consumer of energy, yet little has been written about the forms of lighting that can alter human visual capabilities and enhance productivity, ensure comfort and create appropriate lighting conditions. It is important to understand the forms of lighting available, and their appropriateness to specific activities, in order to apply the technology most effectively. This book is a comprehensive review of the interaction of people and lighting and supercedes the author's classic Human Factors in Lighting. The technology has changed markedly in recent years with the introduction of new light sources and new methods of light distribution. The significance of specialist lighting applications, such as photobiology, are now becoming better understood. The nature of work itself has changed, and hence so have lighting requirements. Equally, the development of the technology has created new opportunities for improving peoples' work and leisure environments.

Non-visual Effects of Light and Colour


Book Description

"Solar radiation has a profound effect on the human organism. This effect might be transformed by artificial illumination. The aim of this bibliography is to bring together in a comprehensive form the existing knowledge regarding the normal physiological and psychological effects of light and colour, including the following topics: Effects of solar radiation on the skin; physiological effects of daylight and artificial illumination entering the eye; preferences for light, colour and visual patterns ; the impact of culture and personality; light and colour in the built environment. Amongst others, the review indicates artificial light might cause stress-like reactions, if it is intense, if the spectrum considerably deviates from that of natural daylight, or if it is flickering and glaring." The bibliography was compiled at the Environmental Psychology Unit, Lund Institute of Technology, with financial support from the Swedish Council for Building Research. It constitutes a CIE TC 3.5 sub-committee report. (240 pages, 1.700 references).
