Patent number: 11424394Abstract: LED packages are disclosed that are compact and efficiently emit light, and can comprise encapsulants with planar surfaces that refract and/or reflect light within the package encapsulant. The LED package are also directed to features or arrangements that allow for improved or tailored emission characteristic for LED packages according to the present invention. Some of these features or arrangements include, but are not limited to, higher ratio of light source size to submount size, the used of particular materials (e.g. different silicones) for the LED package layers, improved arrangement of a reflective layer, improved composition and arrangement of the phosphor layer, tailoring the shape of the encapsulant, and/or improving the bonds between the layers. There are only some of the improvements disclosed herein, with some of these resulting in LED packages the emit light with a higher luminous intensity over conventional LED packages.Type: GrantFiled: October 25, 2019Date of Patent: August 23, 2022Assignee: CreeLED, Inc.Inventors: Arthur Pun, Jeremy Nevins, Jesse Reiherzer, Joseph Clark

Publication number: 20060276038Abstract: Disclosed is a method for removing a layer of native oxide from a surface of a substrate without altering the smoothness of the substrate surface comprising: 1) depositing on the substrate surface a thin sacrificial layer of the substrate surface material, having a thickness sufficient to react with all of the native oxide when the substrate surface is subjected to thermal oxide desorption conditions, and 2) subjecting the substrate to thermal oxide desorption conditions for a time sufficient for all of the native oxide layer to react with the deposited sacrificial layer of substrate material to form volatile reaction products and evaporate from the substrate surface.Type: ApplicationFiled: June 3, 2005Publication date: December 7, 2006Inventors: Arthur Pun, Jian-Ping Zheng
