Publication number: 20080135861Abstract: Light-emitting devices (e.g., LEDs) and methods associated with such devices are provided. In some embodiments, the device includes a distribution of light-generating portions (including active regions) that are spatially localized and separated (e.g., horizontally or vertically) from one or more patterned light extraction portions. This arrangement can allow light generated by the device to propagate and pass through regions of low absorption (e.g., light-extraction portions) rather than in regions of high absorption (e.g., light-generating portions), which can enhance light emission. In some instances, the devices include one or more series of light extraction portions with features arranged in a first and/or second pattern, which may be formed on one or more interfaces of the device (e.g., an emission surface). Patterns can be defined by a series of features (e.g., holes) having certain characteristics (e.g.Type: ApplicationFiled: December 8, 2006Publication date: June 12, 2008Applicant: Luminus Devices, Inc.Inventors: Alexander L.
