Publication number: 20120298888Abstract: In at least one embodiment of the semiconductor light source (1), the latter comprises at least two planar elements (2). The planar elements (2) each contain a semiconductor material for producing ultraviolet or visible radiation (R) when the semiconductor light source (1) is in operation. The radiation (R) is in this case emitted at precisely one major face (3) of the planar elements (2). The reflectivity of the planar elements (2) for visible radiation, when the semiconductor light source (1) is not in operation, amounts to at least 80%. The planar elements (2) furthermore exhibit an average diameter (L) of at least 10 mm. Furthermore the major faces (3) of the planar elements (2) are arranged at an angle (?) to one another and facing one another. The angle (?) between the major faces (3) amounts in this case to between 30° and 120° inclusive.Type: ApplicationFiled: June 30, 2010Publication date: November 29, 2012Inventor: Benjamin Claus Krummacher

Patent number: 8314547Abstract: An optoelectronic device comprises an organic layer sequence (1), which emits an electromagnetic radiation (15) having a first wavelength spectrum during operation, and also a structured layer (2) which is disposed downstream of the organic layer sequence (1) in the beam path of the electromagnetic radiation (15) emitted by the organic layer sequence (1) and has first and second regions (2A, 2B). In this case, the first regions (2A) each have a wavelength conversion layer (3) designed to convert at least partially electromagnetic radiation (15) having the first wavelength spectrum into an electromagnetic radiation (16) having a second wavelength spectrum. Furthermore, the second regions (2B) each have a filter layer (4), which is opaque to an electromagnetic radiation having a third wavelength spectrum, which corresponds to at least one part of the second wavelength spectrum.Type: GrantFiled: August 4, 2008Date of Patent: November 20, 2012Assignee: Osram Opto Semiconductors GmbHInventors: Markus Klein, Norwin Von Malm, Benjamin Claus Krummacher
