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.

Abstract: The invention relates to a thin, nano-structured coating that provides optical light efficiency enhancement. The dried coating contains nano-structures that provide a very low haze level of less than 2 percent, and a light transmission improvement of at least 1% over the non-coated substrate. For the nano-structured coating on an acrylic substrate the transmission is greater than 93 percent, and preferably greater than 94 percent. The coatings of the invention are especially useful for optical electronic displays and photovoltaic modules.

Abstract: The invention relates to an acrylic layer (in the form of a coating, film or sheet) useful as part of a photovoltaic module backsheet. The acrylic layer contains at least 40 percent of one or more acrylic polymers, including an acrylic polymer matrix and optionally acrylic impact modifiers. The acrylic polymer is preferably a polymer, copolymer, or terpolymer containing at least 50 weight percent of methylmethacrylate monomer units. The acrylic layer is flexible and optionally contains high levels of white pigment. It may also contain fluoropolymers such as polyvinylidene fluoride to improve weathering, processibility and film formation. The acrylic layer adheres to a polymer support layer such as polyethylene terephthalate (PET). A preferred substrate is PET that is pre-treated to improve adhesion, but unprimed PET can also be used. The backsheet provides excellent weatherability, environmental stability and reflectivity as part of a photovoltaic module.

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.
