The Competitive Technology Environment for LED Lighting

Abstract

Solid state lighting (SSL) systems are set to begin competing with a number of mature lighting technologies in mainstream markets for narrow-and wide-area illumination. The paper provides a summary overview of the present state of the established i]lvmination iighting sector In terms oi its scale and globa[ energy usage, and its core technologies and their major performance characteristics. The estabiished technologies are themselves stiii evolving in response geneTally to growing, world-wide, legis]ative and environmental pressures, and also, no doubt, to the stimu]us provided by the rapid advances in the pe ormance of white-LED modules. Several promising new thermal and discharge iamp technologies are identified and discussed briefly.
