Publication number: 20200062630Abstract: Methods of producing a glass article include melting a first glass composition and feeding a second glass composition into the melter. Both glass compositions include the same combination of components but at least one component has a concentration that is different in each. At least three glass articles may be drawn from the melter, including: a first glass article formed from the first glass composition; at least one intermediate glass article composed of neither the first nor the second glass composition; and a final glass article not composed of the first glass composition. The concentration of the at least one component in the intermediate glass article may be between the concentration in the first and second glass compositions. The first glass article and final glass article may have differing values for certain properties, and the intermediate glass article may have an intermediate set of values for the same properties.Type: ApplicationFiled: August 16, 2019Publication date: February 27, 2020Inventors: Indrajit Dutta, Jean Marc Galea, Melinda Ann Hourihan, Lisa Ann Lamberson, Robert Michael Morena, Jian-Zhi Jay Zhang

Publication number: 20190202730Abstract: A method of strengthening an alkali aluminoborosilicate glass. A compressive layer extending from a surface of the glass to a depth of layer is formed by exchanging larger metal cations for smaller metal cations present in the glass. In a second step, metal cations in the glass are exchanged for larger metal cations to a second depth in the glass that is less than the depth of layer and increase the compressive stress of the compressive layer. Formation of the compressive layer and replacement of cations with larger cations can be achieved by a two-step ion exchange process. An alkali aluminoborosilicate glass having a compressive layer and a crack indentation threshold of at least 3000 gf is also provided.Type: ApplicationFiled: March 7, 2019Publication date: July 4, 2019Inventors: Sinue Gomez, Lisa Ann Lamberson, Robert Michael Morena

Patent number: 10158057Abstract: Packaged chip-on-board (COB) LED arrays are provided where a color conversion medium is distributed within a glass containment plate, rather than silicone, to reduce the operating temperature of the color conversion medium and avoid damage while increasing light output. A lighting device is provided comprising a chip-on-board (COB) light emitting diode (LED) light source, a light source encapsulant, a distributed color conversion medium, and a glass containment plate. The COB LED light source comprises a thermal heat sink framework and at least one LED and defines a light source encapsulant cavity in which the light source encapsulant is distributed over the LED. The glass containment plate is positioned over the light source encapsulant cavity and contains the distributed color conversion medium. The light source encapsulant is distributed over the LED at a thickness that is sufficient to encapsulate the LED and define encapsulant thermal conduction paths.Type: GrantFiled: March 14, 2013Date of Patent: December 18, 2018Assignee: CORNING INCORPORATEDInventors: Timothy James Orsley, William Richard Trutna, Nicholas Francis Borrelli, Lisa Ann Lamberson, Robert Michael Morena

Patent number: 9540278Abstract: An ion exchangeable glass that is free of lithium and comprising 0.1-10 mol % P2O5 and at least 5 mol % Al2O3. The presence of P2O5 enables the glass to be ion exchanged more quickly and to a greater depth than comparable glasses that do not contain P2O5.Type: GrantFiled: June 24, 2014Date of Patent: January 10, 2017Assignee: Corning IncorporatedInventors: Christy Lynn Chapman, Matthew John Dejneka, Sinue Gomez, Lisa Ann Lamberson

Patent number: 9496521Abstract: Opal glass compositions and devices incorporating opal glass compositions are described herein. The compositions solve problems associated with the use of opal glasses as light-scattering layers in electroluminescent devices, such as organic light-emitting diodes. In particular, embodiments solve the problem of high light absorption within the opal glass layer as well as the problem of an insufficiently high refractive index that results in poor light collection by the layer. Particular devices comprise light-emitting diodes incorporating light scattering layers formed of high-index opal glasses of high light scattering power that exhibit minimal light attenuation through light absorption within the matrix phases of the glasses.Type: GrantFiled: December 11, 2015Date of Patent: November 15, 2016Assignee: Corning IncorporatedInventors: George Halsey Beall, Ivan A Cornejo, Adam James Ellison, Glenn Eric Kohnke, Lisa Ann Lamberson

Publication number: 20160236966Abstract: Strengthened glass substrates with glass frits and methods for forming the same are disclosed. According to one embodiment, a method for forming a glass frit on a glass substrate may include providing a glass substrate comprising a compressive stress layer extending from a surface of the glass substrate into a thickness of the glass substrate, the compressive stress having a depth of layer DOL and an initial compressive stress CSi. A glass frit composition may be deposited on at least a portion of the surface of the glass substrate. Thereafter, the glass substrate and the glass frit composition are heated in a furnace to sinter the glass frit composition and bond the glass frit composition to the glass substrate, wherein, after heating, the glass substrate has a fired compressive stress CSf which is greater than or equal to 0.70*CSi.Type: ApplicationFiled: April 21, 2016Publication date: August 18, 2016Inventors: Melinda Ann Drake, Lisa Ann Lamberson, Robert Michael Morena

Patent number: 8822032Abstract: The disclosure is directed to glass frits materials containing phosphors that can be used in LED lighting devices and for methods associated therewith for making the phosphor containing frit materials. Suitable non-lead glasses have a composition, in mol %, in the range of 20-24% K2O, 8-12% ZnO, 2-6% Al2O3, 35-41% B2O3 and 22-28 SiO2. Suitable leaded glasses have a composition, in wt %, in range of 72-79% PbO, 8-13% Al2O3, 8-13% B2O3, 2-5% SiO2 and 0-0.3% Sb2O3. Commercial high-lead glass can be used in practicing the disclosure. Among the unique advantages are the ability to blend two or more phosphors within the same frit layer which will yield a multi-phosphor-containing glass after firing; the ability to deposit the phosphor onto a substrate into a desired geometric pattern; and the fluorescing layer can be applied to the active plane, with the glass serving as protective substrate.Type: GrantFiled: October 26, 2011Date of Patent: September 2, 2014Assignee: Corning IncorporatedInventors: Nicholas Francis Borrelli, Lisa Ann Lamberson, Robert Michael Morena, William R Trutna
