Abstract
Traditionally, architectural lighting has been engineered to deliver horizontal illuminance to they workplane in order to provide adequate illumination for visual tasks. Gradually, lighting designers and manufacturers began to consider the aesthetic as well as psychological effects of light, such as perceived brightness of a space, and developed techniques to distribute the light not just on the horizontal surfaces of a room, but on the vertical ones as well. More recently, the scope of architectural lighting has broadened further to include the physiological effects of light, specifically how light affects the human circadian system and alertness.
