Patent number: 8217589Abstract: A method is provided for driving at least one lamp unit, which is connected to an AC voltage power supply system. The method comprises modulating a control information item for the operation of the lamp unit onto the supplied AC voltage, decoding of the modulation received on the lamp unit side for reading the control information item and driving the light-emitting device in accordance with the control information item. Provision is made for a shunt to be produced in the line used for transmitting the control information item prior to or at the beginning of the modulation of the control information item. The disclosure also provides a lamp unit and a control device for implementing the method. The disclosure also provides a lighting system.Type: GrantFiled: January 22, 2010Date of Patent: July 10, 2012Assignees: Osram Gesellschaft mit beschrankter Haftung, Insta Elektro GmbHInventors: Helmut Endres, Klaus Fischer, Friedhelm Holtz, Karl-Heinz Krause, Josef Kreittmayr, Friedhelm Wehlmann

Patent number: 8139335Abstract: A protective circuit for electrical connection to solar cells of a solar cell module is provided with a protective circuit that has a controlled electronic circuit arrangement. In this way, only minimal heating of the protective circuit for electrical connection of solar cells of a solar cell module occurs in operation. The controlled electronic circuit arrangement can have a trigger circuit and a switching arrangement which can be triggered by the trigger circuit, the switching arrangement being connected parallel to at least one solar cell, and in the case of shading of the solar cells, is at least temporarily activated by the trigger circuit so that a current bypass for the shaded solar cell is achieved.Type: GrantFiled: November 29, 2010Date of Patent: March 20, 2012Assignees: Guenther Spelsberg GmbH & Co. KG, INSTA Elektro GmbHInventors: Dirk Quardt, Volker Grosch, Thomas Grossen, Harald Mundinger
