Patent number: 8831060Abstract: The invention relates to a laser (1) for emitting laser light in the visible spectral range. A rare earth doped anisotropic crystal (2) comprising a 5d-4f transition is arranged within a laser resonator (7, 8), and a pumping light source (3) pumps the crystal (2) for generating laser light in the visible spectral range by using the 5d-4f transition. The 5d-4f transition of the rare earth doped anisotropic crystal comprises an absorption band extending over several nm. Thus, pump light having a wavelength within a relatively broad wavelength range can be used. This reduces the requirements with respect to the wavelength accuracy of the pumping light source and, thus, more pumping light sources of an amount of produced pumping light sources can be used for assembling the laser, thereby reducing the amount of rejects.Type: GrantFiled: June 10, 2011Date of Patent: September 9, 2014Assignee: Koninklijke Philips N.V.Inventors: Ulrich Weichmann, Matthias Alexander Wilhelm Fechner, Fabian Reichert, Herbert Walter Klaus Petermann, Gunter Huber

Patent number: 7821196Abstract: An illumination device with at least one LED as the light source, the LED emitting primary radiation in the range from 370 to 430 nm of the optical spectral region (peak wavelength), this radiation being partially or completely converted into radiation of a longer wavelength by three phosphors which are exposed to the primary radiation from the LED and which emit in the blue, green and red spectral regions, so that white light is formed. The conversion is achieved at least with the aid of a phosphor which emits blue light with a wavelength maximum at 440 to 485 nm, and with the aid of a phosphor which emits green light with a wavelength maximum at 505 to 550 nm, and with the aid of a phosphor which emits red light with a wavelength maximum at 560 to 670 nm.Type: GrantFiled: March 20, 2007Date of Patent: October 26, 2010Assignees: OSRAM Gesellschaft mit beschränkter Haftung, OSRAM Opto Semiconductors GmbHInventors: Dieter Bokor, Andries Ellens, Günter Huber, Frank Jermann, Manfred Kobusch, Michael Ostertag, Wolfgang Rossner, Franz Zwaschka

Patent number: 7265487Abstract: A discharge lamp (1) having a discharge vessel (2) which surrounds a discharge medium which emits electromagnetic radiation in the VUV region when the lamp is operating has, on the inner side of the discharge vessel wall, a first phosphor layer, which faces the discharge medium and comprises a UVA component which can be excited by the VUV radiation and is intended to emit electromagnetic radiation in the UVA region. A second phosphor layer, which can be excited by the UVA radiation and is intended to emit electromagnetic radiation in the visible region either lies beneath the first phosphor layer or is applied to the outer side of the discharge vessel wall. This results in a lower color locus shift compared to a conventional phosphor mixture, which can be excited directly by VUV radiation.Type: GrantFiled: May 25, 2004Date of Patent: September 4, 2007Inventors: Günter Huber, Frank Jermann, Ulrich Müller, Martin Zachau
