Publication number: 20100238633Abstract: A power circuit (10) for activating a drive unit for a wiper system of a motor vehicle has a circuit breaker (14) for activating the drive unit. According to the invention a heat accumulator (16) for absorbing heat accumulating in the circuit breaker (14) when the drive unit is in the blocked state is thermally connected to the circuit breaker (14). In the event of sudden heat generation in the circuit breaker (14) a majority of the resulting heat can be discharged quickly to the heat accumulator (16) such that the circuit breaker (14) can be smaller in size and the power circuit (10) enables use of a higher-ohm circuit breaker (14).Type: ApplicationFiled: October 27, 2008Publication date: September 23, 2010Applicant: ROBERT BOSCH GMBHInventors: Gebhard Michenfelder, Stephan Pauli

Patent number: 7800909Abstract: A lamp base having a heat sink is connected to a bulb having two electrodes. The lamp base includes a heat sink, a first electrically conductive piece, a second electrically conductive piece, and leads. The heat sink comprises a heat-dissipating base formed with a trough for accommodating the bulb therein. The first electrically conductive piece is fixed in the trough and is electrically connected to an electrode of the bulb. The second electrically conductive piece is fixed in the trough and is electrically connected to the other electrode of the bulb. The second electrically conductive piece is electrically insulated from the first electrically conductive piece. The leads are electrically connected to the first electrically conductive piece and the second electrically conductive piece respectively. With the heat sink dissipating the heat generated by the bulb, the lamp base has extended lifetime.Type: GrantFiled: October 27, 2008Date of Patent: September 21, 2010Assignee: Edison Opto CorporationInventor: Tsung-Ting Sun
