Insulated glass units (IGUs) are fabricated from the electrochromic panes and optionally one or more of the panes of the IGU are strengthened.Type: GrantFiled: November 8, 2010Date of Patent: April 24, 2012Assignee: Soladigm, Inc.Inventors: Mark A. Collins, Ronald M. Parker, Robert T. Rozbicki, Dhairya Shrivastava

Publication number: 20110310458Abstract: A transparent smart light source capable of adjusting an illumination direction is provided. The transparent smart light source includes a reflectance/transmittance tunable device that adjusts an illumination direction by reflecting or transmitting light emitted from a transparent organic light-emitting diode (OLED) according to applied voltage, and thus can simply adjust the illumination direction according to purpose. Accordingly, it is possible to prevent optical loss in an unnecessary direction, and power consumption can be reduced. Furthermore, the transparent smart light source can serve as a curtain blocking out external light, as well as a lighting device, and also can be combined with a solar cell to generate electric power.Type: ApplicationFiled: June 16, 2010Publication date: December 22, 2011Applicant: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Jeong Ik LEE, Hye Yong CHU, Jong Hee LEE
