Architectural lighting design
""The Sun never knew how great it was until it hit the side of a building."" Louis KahnArchitectural lighting design is a field within architecture, interior design and electrical engineering that is concerned with the design of lighting systems, including natural light, electric light, or both, to serve human needs.The design process takes account of: the kind of human activity for which lighting is to be provided. the amount of light required. the colour of the light as it may affect the views of particular objects and the environment as a whole. the distribution of light within the space to be lighted, whether indoor or outdoor. the effect of the lightened system itself on the user.It is important to appreciate that the ultimate criterion of success in lighting is the human response, that is. whether what is to be seen clearly, easily and without discomfort."" Lighting designers are often specialists who must understand the physics of light production and distribution, the physiology and psychology of light perception by humans, the anatomy of the human eye, and the response of the rods and cones to light.
