Patent number: 10980132Abstract: LEDs for an illumination system may be mounted on a PCB. The PCB may be provided with alignment features such as oversized holes for connection to a support surface. Using optical sensing of the position of the mounted LEDs, the space made available by the alignment features may be reduced and aligned to create modified alignment features. The modified alignment features may be created by adding a modifying component and aligned based on the sensed positions of the mounted LEDs. The positioning of the modifying component may offset misalignment of the LEDs with the PCB. An opening in the modified alignment feature may receive a bolt or alignment pin for connection to the support surface. The support surface may be aligned with the secondary optics, resulting in the LEDs being aligned with the secondary optics irrespective of misalignment of the LEDs with respect to the PCB.Type: GrantFiled: July 14, 2020Date of Patent: April 13, 2021Assignee: Lumileds LLCInventor: Axel Mehnert

Patent number: 10340432Abstract: A light emitting device is provided that includes an integral heat dissipation element. This heat dissipation element is included in the leadframe that is used to facilitate fabrication of the light emitting device, to provide a single common substrate that forms both the heat dissipation element and the conductive elements for coupling the light emitting device to external sources of power. The heat dissipation element may extend beyond the protective structure that surrounds the light emitting element to facilitate heat dissipation to the surrounding medium.Type: GrantFiled: December 30, 2015Date of Patent: July 2, 2019Assignee: Lumileds LLCInventors: Axel Mehnert, Dusan Golubovic, Marcus Franciscus Donker, Hendrik Jan Eggink, Rene Van Honschooten, Theodoor Cornelis Treurniet

Patent number: 10237980Abstract: A patterned conductive layer on a flexible substrate includes pads for mounting an array of LEDs, conductive strips, and conductive tabs that couple the conductive strips to the pads. The desired circuit configuration is created by removing select tabs by punching holes or otherwise piercing the flexible substrate at the location of the tabs. In some embodiments, the patterned conductive layer is arranged to permit each LED to be mounted in either of two mirrored orientations, and in some embodiments, the patterned conductive layer is arranged to permit a separation between LEDs that is not predefined by the pattern. In some embodiments, the unmodified patterned conductive layer is arranged to provide a parallel circuit configuration, and the modified patterned conductive layer is arranged to provide a series or series-parallel configuration.Type: GrantFiled: December 16, 2014Date of Patent: March 19, 2019Assignee: Lumileds LLCInventors: Frederic Stephane Diana, Patrick Allen Bournes, Walter Daeschner, Yong Seok Choi, Axel Mehnert, Mohiuddin Mala

Publication number: 20180358527Abstract: Cathode and anode electrodes are located on the bottom surface of an LED submount along a center line of the bottom surface. Two thermal pads are located on either side of the electrodes along opposite sides of the bottom surface. This configuration results in less stress on solder bonding the electrodes to a circuit board. Further, since the heat conducted by the two thermal pads is not choked by the electrodes, the heat spreads more uniformly into the circuit board. Further, since the metal design is symmetrical in that the outer thermal pads are identical, the molten solder will have the same shape over both thermal pads, causing the LED die and submount to be not tilted with respect to the surface of the circuit board. Other configurations are described that also improve the thermal and electrical characteristics of the LED die.Type: ApplicationFiled: November 23, 2016Publication date: December 13, 2018Applicant: Lumileds Holding B.V.Inventor: Axel MEHNERT

Patent number: 8717827Abstract: Data bits are programmed in cells of a flash memory which is divided into a multiplicity of separately erasable physical blocks, which are in turn split into individual physical pages to which the data bits can be written. The data bits are held in multilevel cells that store one lower bit and one upper bit per cell. The four states of which are distinguished by three voltage threshold values. The lower states are associated with the lower bit and the upper states are associated with the upper bit. The pages are distinguished by lower pages allocated to the lower bits, and upper pages allocated to the upper bits. Lower and upper pages which contain the same cells are combined by a pairing table to form paired pages. Reliable storage of data bits is achieved by programming paired pages with the same data bits and listing them as reliable paired pages in management data for the flash memory.Type: GrantFiled: February 22, 2013Date of Patent: May 6, 2014Assignee: Hyperstone GmbHInventors: Axel Mehnert, Franz Schmidberger, Christoph Baumhof

Publication number: 20140068390Abstract: An apparatus and a method for correcting data errors in a data block. The data block contains original data which are supplemented by such a security syndrome that the data block effects a correction of at most t data errors, wherein a parallel-operating quick corrector is used. The quick corrector is only designed for a correction of a subset t1 of the set of the at most t data errors, and the quick corrector includes a test encoder, which sets a first test state flag P1 which, in the event of a complete correction of a processed data block, outputs this data block and secondly activates a series-operating post-corrector for at most t data errors. The output signal of the post-corrector is output as an alternative.Type: ApplicationFiled: October 13, 2011Publication date: March 6, 2014Applicant: HYPERSTONE GMBHInventors: Franz Schmidberger, Christoph Baumhof, Axel Mehnert, Steffen Allert

Patent number: 7679843Abstract: The invention relates to an adjustment method, especially for adjusting optical or fiber optical components. According to an embodiment of the invention, a first adjustment process is carried out in which, after a cooling process, the regions of the actuator in which the tensile stresses or compressive strains are frozen following the cooling process are brought to a critical temperature in relation to the operational temperature range of the actuator, at least until the flow processes of the material at said critical temperature are largely completed. A second adjustment process is then carried out.Type: GrantFiled: June 12, 2002Date of Patent: March 16, 2010Assignee: Finisar CorporationInventors: Burkhard Arthur Seitz born Müller, Klaus Strol, Axel Mehnert
