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

Abstract: Optically transparent, conductive polymer compositions and methods for making them are claimed. These conductive polymer compositions comprise an oxidized 3,4-ethylenedioxythiopene polymer, a polysulfonated styrene polymer, single wall carbon nanotubes and/or metallic nanoparticles. The conductive polymer compositions can include both single wall carbon nanotubes and metallic nanoparticles. The conductive polymer compositions have a sheet resistance of less than about 200 Ohms/square, a conductivity of greater than about 300 siemens/cm, and a visible light (380-800 nm) transmission level of greater than about 50%, preferably greater than about 85% and most preferably greater than about 90% (when corrected for substrate). The conductive polymer compositions comprising single wall carbon nanotubes are made by mixing the oxidized 3,4-ethylenedioxythiopene polymer and polysulfonated styrene polymer with single wall carbon nanotubes and then sonicating the mixture. The conductive polymer compositions comprising metallic nanoparticles are made by a process of in situ chemical reduction of metal precursor salts.

Abstract: The invention relates to optical light diffusers for use with point light sources, such as LED lighting. The optical diffusers achieve an optimum balance of light transmission and hiding power. The optical light diffuser is a transparent plastic matrix, such as Plexiglas® resin from Arkema Inc., having organic particles dispersed within the matrix. The particles are crosslinked beads having specific particle sizes and loading. Different beads can be combined to provide added properties such as a textured surface, and to optimize hiding power and light transmission. The invention also relates to a luminous device containing at least one light-emitting diode and a cover made of the optical light diffuser. The invention further relates to a method for assessing hiding power.
