Abstract
The invention relates to blend materials useful in LED lighting applications. The diffusing particle blend is a synergistic mixture of selected organic particles and selected inorganic particles of specific composition, loading, and a refractive index difference with the matrix polymer, that provide excellent light diffusion, high hiding properties and good light transmission. Articles made of this blend are useful in commercial and residential lighting, motor vehicle illumination (lights, panels), street lighting, displays and signs.
