A multi-reflector lighting apparatus including a reflector having a reflecting layer deposited on a base layer. The multi-reflector lighting apparatus further includes a first oxide layer deposited on the reflecting layer. The multi-reflector lighting apparatus further includes a second oxide layer deposited on the first oxide layer. The multi-reflector lighting apparatus further includes an alternating plurality of a relatively low refractive index oxide layer material and a relatively high refractive index oxide layer material deposited on the second oxide layer.

Reflecting apparatus including enhanced aluminum optical coatings

Provided is a multi-layer reflective coating for application to a lighting housing assembly, including a polymer substrate adjacent a polymer base coat layer applied to the lighting housing. Atop the polymer base coat layer is an aluminum adhesion layer, followed by a diffusive barrier layer, and a silver reflective layer. The aluminum adhesion layer promotes adhesion between the polymer base coat layer and the silver reflective layer. The diffusive barrier layer prevents aluminum and silver interaction, which could form a silver and aluminum alloy. A spectrum tunable layer is applied atop the silver reflective layer for spectrum tuning the silver reflective layer for maximum compatibility with a light emitting diode (LED) lighting source.

A multilayer coating systems suitable for use as optical interference filters in lighting systems, for example, halogen lamps. Such an optical interference filter contains alternating layers of a high refractive index material and a low refractive index material. The high refractive index material consists of niobia, titania, and incidental impurities and contains either about 25 to less than 50 mol % titania and the balance niobia and incidental impurities, or contains about 60 to about 80 mol % titania and the balance niobia and incidental impurities.

Optical interference filters, and filament tubes and lamps provided therewith

Example embodiments relate to a method and apparatus for reducing electrostatic deposition of charged particles on wetted surfaces that are exposed, periodically or substantially continuously, to high velocity fluid flow within a coolant flow path in a nuclear reactor. The method may include depositing a first or base dielectric layer and a second or outer dielectric layer on a conductive surface that forms a portion of a high velocity flow path to attain the apparatus. The first dielectric layer material is selected to provide improved adhesion and insulation to the conductive surface and the second dielectric layer material is selected to provide suitable adhesion to the first dielectric layer and improved corrosion and/or mechanical resistance in the anticipated operating environment.

A reflector lamp has a generally parabolic shaped housing () with an interior surface coated with a layer () of silver having a protective layer () of a stable protective material, such as silica, disposed thereon. The thickness of the protective layer is selected such that at least one of the following relationships is satisfied: a color correction temperature of the lamp is no less than about 60 K below that of the light source, and a % reflectance of the reflective interior surface is no less than about 3% below that of an equivalent reflective interior surface without the protective layer.

Optimal silicon dioxide protection layer thickness for silver lamp reflector

An electric lamp assemblyfor emitting near infrared radiation includes a reflector housingand a lamp vesselpositioned within the reflector housing. A source of illuminationis enclosed within the lamp vessel. A continuous multi-layer interference filmon an exterior surfaceof the lamp vessel transmits near infrared radiation within the range of 850-1100 nm and is substantially non-transmissive towards visible radiation.

Lamp for night vision system

A reflector lamp has a generally parabolic shaped housing ( ) with an interior surface coated with a layer ( ) of silver having a protective layer ( ) of a stable protective oxide, such as silica, disposed thereon. An intermediate layer ( ), such as a layer of elemental silicon, protects the silver layer during deposition of the silica layer and is completely or substantially consumed during formation of the silica layer. The lamp includes a light source ( ) having a longitudinal axis (x) disposed on the parabolic reflector axis and preferably disposed outward of the parabolic focus (F). During lamp fabrication, the protective coating is preferably annealed to improve reflectance. The preferred lamp will have a lumens per watt greater than 14.

Protected coating for energy efficient lamp

A parabolic reflector lamp is provided wherein lamp efficiency is improved by more substantially approximating the shape of a complete parabola at the inner reflective surface. In a first embodiment, the heat shield is placed at the mouth of the opening at the base of the lamp, thereby &ldquo;filling in&rdquo; the opening and substantially completing the parabolic shape of the reflector. In a second embodiment, the opening at the base of the lamp is narrowed to minimize its cross-sectional area and maximizing reflective surface area. In a third embodiment, the glass shell of the lamp is provided in a two-piece configuration, allowing the size of the hole through the base of the glass shell to be reduced. The openings required to accommodate electrodes (and an exhaust tube in sealed lamps) are located in a second cup-shaped piece attached via a flange to the main body of the glass shell.

Reflector lamps

The invention is related to a reflector lamp comprising a parabolic primary reflecting section, a parabolic or spheric secondary reflecting section joined to the primary reflecting section, a parabolic or spheric tertiary reflecting section joined to the secondary reflecting section, and an incandescent or discharge light source. The secondary and tertiary reflecting sections have faceted surfaces which longitudinally extend along the surface thereof so that most (at least 50%) or substantially all the light reflected by the faceted surfaces avoids the light source and thus the light, which would be absorbed or scattered by the light source, is minimized or substantially eliminated.

Reflector lamp having a reflecting section with faceted surfaces

A magnetron sputtering device and method for applying an interference layer to a substrate includes a magnetron sputtering chamber (A) which houses a substrate carrying assembly (B). The substrate carrying assembly comprises a primary rotation table ( ), rotating about its central vertical axis ( ) and at least one secondary table ( ) mounted to an upper surface ( ) of the primary rotation table. Substrates ( ) are either horizontally or vertically loaded on to the secondary table. The substrates rotate about their symmetrical axis. First and second targets ( ) are housed by the chamber and are disposed on opposite sides of the chamber. The primary rotation table rotates the substrates between a position adjacent a first target where a layer having a low refractive index is applied to the substrates and a position adjacent a second target where a layer having a high refractive index is applied to the substrates.
