A light-reflecting article having an average total reflectivity of at least about 93%, e.g., at least about 95%, for light in a 400 to 700 nanometer wavelength range comprises a thermoplastic or thermoset polymer matrix, such as an acrylonitrile-butadiene-styrene-based matrix, in which is dispersed reflective filler particles such as rutile titania and a flame-retardant material. The flame-retardant material may contain a particulate metal oxide synergist, e.g., antimony trioxide or antimony pentoxide, and a quencher such as a brominated organic compound, e.g., bis(tribromophenoxy)ethane. The polymer matrix and filler may be selected so that their respective refractive indices and the size range of the filler particles satisfies a mathematical relationship having as a function thereof the mean freespace (vacuum) wavelength of the light range being reflected. The article may comprise a light-reflecting enclosure ( ) of an illumination source ( ), the enclosure ( ) having at least one linear aperture ( ) formed therein and enclosing a linear light source ( ).

Light-reflecting molded articles and methods of making the same

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.
