934 results about "Low emissivity" patented technology

Low emissivity (low e or low thermal emissivity) refers to a surface condition that emits low levels of radiant thermal (heat) energy. All materials absorb, reflect and emit radiant energy according to Planck's law but here, the primary concern is a special wavelength interval of radiant energy, namely thermal radiation of materials. In common use, especially building applications, the temperature range of approximately -40 to +80 degrees Celsius is the focus, but in aerospace and industrial process engineering, much broader ranges are of practical concern.

Solar control coated glass

A solar-control glass that has acceptable visible light transmission, absorbs near infrared wavelength light (NIR) and reflects midrange infrared light (low emissivity mid IR) along with a preselected color within the visible light spectrum for reflected light is provided. Also provided is a method of producing the improved, coated, solar-controlled glass. The improved glass has a solar energy (NIR) absorbing layer comprising tin oxide having a dopant such as antimony and a low emissivity control layer (low emissivity) capable of reflecting midrange infrared light and comprising tin oxide having fluorine and / or phosphorus dopant. A separate iridescence color suppressing layer as described in the prior art is generally not needed to achieve a neutral (colorless) appearance for the coated glass, however an iridescence suppressing layer or other layers may be combined with the two layer assemblage provided by the present invention. If desired, multiple solar control and / or multiple low emissivity layers can be utilized. The NIR layer and the low emissivity layer can be separate portions of a single tin oxide film since both layers are composed of doped tin oxide. A method of producing the coated solar control glass is also provided.

Coated article including low-emissivity coating, insulating glass unit including coated article, and/or methods of making the same

Certain example embodiments relate to a coated article including at least one infrared (IR) reflecting layer of a material such as silver or the like in a low-E coating, and methods of making the same. In certain cases, at least one layer of the coating is of or includes nickel and / or titanium (e.g., NixTiyOz). The provision of a layer including nickel titanium and / or an oxide thereof may permit a layer to be used that has good adhesion to the IR reflecting layer, and reduced absorption of visible light (resulting in a coated article with a higher visible transmission). When a layer including nickel titanium oxide is provided directly over and / or under the IR reflecting layer (e.g., as a barrier layer), this may result in improved chemical and mechanical durability. Thus, visible transmission may be improved if desired, without compromising durability; or, durability may simply be increased.

Thermal control interface coatings and pigments

The invention provides an optical structure with low chroma and brightness in the visible region and low emissivity in the infrared region. The optical structure includes an interference structure having an infrared reflective layer and an infrared absorbing thin film layer. These layers are in turn separated by a thin film spacer of a dielectric or semiconductor material. The reflectivity and transmission of the layers are selectively controlled through the thickness of the layers such that the visual reflectivity and color is independent of the infrared properties of the absorber and reflector layers.

Cooling device, and apparatus and method for manufacturing image display panel using cooling device

The present invention provides a cooling device used for a process for heating and cooling a substrate constituting an image display apparatus that uses electron emitting devices. The cooling device includes a cooling plate located opposite the substrate to absorb radiation heat from the substrate. The cooling plate is provided with a high emissivity area in a pattern located opposite to a low emissivity area of the substrate. This suppresses a variation in a temperature distribution in the substrate during cooling, thus preventing the substrate from being distorted or damaged.

InactiveUS20090128893A1Increasing effective insulation valueDecreased emissivityMirrorsDecorative surface effectsGratingBlack-body radiation
A high-transparency, low-emissivity window film or coating is designed to maximize so-called greenhouse heating. This effect is achieved through the use of conductive grids and / or gratings whose width and spacing has been selected such that the grid appears as a uniform conductive film to long-wavelength infrared (blackbody) radiation. The conductive grid film reflects the blackbody radiation strongly, and such that the grid appears highly transparent to visible and near-infrared light, and therefore transmits it.
