Abstract
An illumination system is provided. The illumination system comprises an array of light emitting elements, an array of directional optical elements and a light deflecting means arranged to provide a fan of light cones. A position detector senses the retroreflection from an observer's eyes and a control system reduces the intensity of light directed towards the retroreflection region. Such a system achieves glare reduction for a line-of-sight illumination apparatus.
