Abstract
Improved linear illumination sources are disclosed which utilize external, highly reflective enclosures containing one or more linear openings and thereby achieve improved source efficiency, output irradiance and/or output radiance. Such improved illumination sources may be combined with additional optical elements to produce more complex illumination systems.
