Nowadays cities are bathed in light. Ever since man began travelling in space and satellites beamed back photographs, like mirror images of the earth from thousands of miles of miles away, we have been able to see that large urban concentrations look like enormous pool of light in the darkness. Light could be used to convert a simple fa?ade into an interface between the city and the world. Advances in illumination systems, and, above all, the continually increasing use of LED technology have created works of art from the facades of corporate buildings, museums, institutions and commercial centres as well as landscapes and urban spaces. This book features a selection of projects which were designed around the idea of how light should be used in a certain space. Each of them presents a special and unique concept of illumination, developed with the intention of transmitting emotions, artistic expression or information or to create an area using light, spaces, colour and shadows. In their wide variety, they all assert the essential role light plays in creating an architectural space.
