Publication number: 20070295981Abstract: Light-emitting devices (e.g., LEDs) and methods associated with such devices are provided. The devices may include a first pattern and a second pattern which are formed at one or more interfaces of the device (e.g., the emission surface). The patterns may be positioned such that light generated by the device passes through the interfaces of the patterns when being emitted. The patterns can be defined by a series of features (e.g., vias, posts) having certain characteristics (e.g., feature size, depth, periodicity, nearest neighbor distance, etc.) which may be controlled to influence properties of the light emitted from the device, including improving extraction and/or collimation of the emitted light.Type: ApplicationFiled: February 9, 2007Publication date: December 27, 2007Applicant: Luminus Devices, Inc.Inventors: Alexei Erchak, Michael Lim, Elefterios Lidorikis, Jo Venezia, Robert Karlicek, Nikolay Nemchuk

Patent number: 7196354Abstract: A light-emitting device is provided. The device may include a thermally conductive region in contact with a wavelength-converting region (e.g., a phosphor region). The thermally conductive region may aid in the extraction of heat resulting from light absorption in the wavelength-converting region, which, if excessive, may impair device operation. The presence of a thermally conductive region can enable devices including wavelength-converting regions to operate even at high power levels (e.g., light generated by the light-generating region and/or by the light-emitting device having a total power greater than 0.5 Watts) for long operating lifetimes (e.g., greater than 2,000 hours).Type: GrantFiled: September 29, 2005Date of Patent: March 27, 2007Assignee: Luminus Devices, Inc.Inventors: Alexei A.
