摘要： A broadband, omnidirectional, multi-layer, dielectric reflector for an LED in a white light emitting device provides both near 100% reflectivity across the visible spectrum of light, and electrical insulation between the substrate and the electrical circuitry used to power and control the LED. When a sealant material, having a higher index of refraction than air, is used to protect the LED and the accompanying electrical circuitry, an aluminum reflector layer or substrate is provided to make up for the loss of reflectivity at certain angles of incidence. The dielectric reflector includes two separate sections with two different thicknesses, a thinner section below the LED providing better heat conductivity, and a thicker section surrounding the LED providing better reflectivity.

摘要： Multilayer chromatic diffractive pigment flakes and foils are provided having diffractive structures thereon. The diffractive pigment flakes can have a symmetrical stacked coating structure on opposing sides of a reflective core layer, an asymmetrical stacked coating structure on one side of a reflective layer, or can be formed with one or more encapsulating coatings around the reflective core layer. The diffractive pigment flakes can be interspersed into liquid media such as paints or inks to produce diffractive compositions for subsequent application to a variety of objects. The foils can be laminated to various objects or can be formed on a carrier substrate. The diffractive pigment flakes and foils can be formed with a variety of diffractive structures thereon to produce selected optical effects.

摘要： A color shifting multilayer interference film is provided which may be used to produce flakes for use in colorants having color shifting properties. The flakes can be interspersed into liquid media such as paints or inks which can subsequently be applied to objects or papers to achieve color variations upon shifts in angle of incident light or upon shifts in viewing angle. A five layer design of the interference film includes a first absorber layer, a first dielectric layer on the first absorber layer, a reflector layer on the first dielectric layer, a second dielectric layer on the reflector layer, and a second absorber layer on the second dielectric layer. The first and second dielectric layers are formed to have an optical thickness at a design wavelength that provides a color shift as the angle of incident light or viewing changes.

摘要： A linear aperture deposition apparatus and process are provided for coating substrates with sublimed or evaporated coating materials. The apparatus and process are particularly suited for producing flexible films having an optical interference coating with a very high surface thickness uniformity and which is substantially free of defects from particulate ejection of a source material. The apparatus includes a source box containing a source material, a heating element to sublime or evaporate the source material, and a chimney to direct the source material vapor from the source box to a substrate. A flow restricting baffle having a plurality of holes is positioned between the source material and the substrate to confine and direct the vapor flow, and an optional floating baffle is positioned on the surface of the source material to further restrict the vapor flow, thereby substantially eliminating source material spatter.
