Patent number: 10260705Abstract: An LED module combines a heat sink portion and an LED arrangement. The heat sink portion is a first part of a multiple part heat sink having at least this first part and a second part. The heat sink portion is not sufficient alone to provide the required cooling for the operation of the LED arrangement so it can be small and low cost. A user can simply replace the LED module as a single unit, without the significant waste and cost of disposing of the full heat sink.Type: GrantFiled: March 31, 2016Date of Patent: April 16, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Jürgen Gerhard Mertens, Astrid Marchewka, Ralph Hubert Peters, Benno Spinger, Georg Friedrich Alfons Henninger

Patent number: 9414473Abstract: A lamp 10 is described comprising a burner 14 fixed to a lamp base 12. An operating circuit 50 is arranged within the lamp base 12 for supplying electrical power to the burner 14. The operating circuit 50 is electrically connected to at least one elongate contact path element 70 extending within the base. The contact path element 70 is supported within the base 12 and comprises a first portion 70a fixed within the base and a second portion 70b slidably received within the base 12. The contact path element 70 is fixed to the operating circuit 50 at a position arranged in longitudinal direction from the second portion 70b. This allows a manufacturing method, where the contact path element is fixed to the operating circuit 50 at a position arranged in longitudinal direction from the second portion, so that a longitudinal movement of the second portion is possible to compensate for manufacturing tolerances.Type: GrantFiled: April 9, 2013Date of Patent: August 9, 2016Assignee: Koninklijke Philips N.V.Inventors: Lars Dabringhausen, Juergen Gerhard Mertens, Anton Duschl

Publication number: 20150142399Abstract: In a computational environment including at least one processor, an example method of reducing the number of symbolic parameters in a model of a physical system includes receiving an initial model such as a system of differential algebraic equations (DAEs), eliminating isolated symbolic parameters (if any) from the initial model, extracting parameter sub-expressions from the DAEs, establishing minimal disconnected clusters of parameter sub-expressions, and for each cluster, attempting to generate a reduced cluster having a reduced number of symbolic parameters using one or more algorithms. If more than one approach is successful, that which is most successful in reducing the number of symbolic parameters is selected. A revised model is created having fewer symbolic parameters than the initial model and based on simulation results obtained from the revised model, a prototype of a physical system is manufactured and/or changes are made to an existing physical system.Type: ApplicationFiled: December 15, 2014Publication date: May 21, 2015Inventors: Erik Jelle Postma, Jürgen Gerhard, Elena Shmoylova, Austin Duncan Roche
