摘要：The invention relates to high efficiency diffusion lighting coverings useful in LEDlighting applications. The diffusing lighting coverings are made of organic diffusingparticles homogeneously dispersed in a transparent polymer matrix. The primary organicdiffusing particles are refractive index mis-matched to the matrix polymer. The refractiveindex contrast between the polymer matrix and diffusion particles, and particle size areselected to provide a high efficiency (minimized particle loading). The high efficiencydiffusion coverings provides excellent light diffusion, high hiding properties and high lighttransmission. The secondary diffusion particles may optionally be added to furtherimprove selected target properties of the covering. Nano-sized ZnO inorganic particlesmay also function as diffusion particles and optical brighteners as well UV stabilizers.Articles made of this translucent composition are useful in commercial and residentiallighting, motor vehicle illumination (lights, panels), street lighting, displays and signs,desktop monitors, and LCD/LED TVs.
