Abstract:
The invention proposes an assembly including a printed-circuit electronics card (2) mounted on a metal substrate (1), as well as a metal screening cover (3) electrically connected to the substrate (1). The substrate (1) exhibits a recessed gutter (4) in which the edge of the cover (3) is accommodated. The said edge is crimped onto the said substrate (1) in the gutter (4). The invention also proposes a method of producing such an assembly.
Abstract:
The present invention relates to a light device comprising in particular a complementary module receiving a set of signals via a first electrical connection, and a light element comprising at least one element generating electromagnetic interference, each element generating electromagnetic interference being supplied via a distinct complementary electrical connection, the first electrical connection and each complementary electrical connection being connected to a single connector. The connector comprises a first set of contact areas of the first electrical connection and at least one set of complementary contact areas, each set of complementary contact areas being intended to receive one of the complementary electrical connections, only the set of complementary contact areas being surrounded separately by an electromagnetic shielding element. The invention also relates to the motor vehicle equipped with such a light device.
Abstract:
The assembly has a metal sole plate forming a heat sink carrying a printed circuit card. The sole plate includes bearing surfaces which project slightly beyond the rest of the sole plate. The printed circuit is supported on these bearing surfaces and they include fixing means which interact with supplementary means of the printed circuit card to fix the printed circuit card onto the sole plate. A thermally conducting and electrically insulating material is interposed between the said card and the sole plate. The printed circuit card and the sole plate exert compression stress on the thermally conducting and electrically insulating material.
Abstract:
A method for managing a gas discharge lamp in particular for a motor vehicle headlamp. The method is of the type which consists in controlling initial and nominal supply powers of the lamp by means of control signals during the operating phases of the lamp which comprise a start-up phase, an ignition phase and a steady-state phase. The method is wherein the control signals comprise command signals which are generated externally of the ballast and which force each of the supply powers to a value selected from a set of predetermined powers as a function of each of the phases. The method makes it possible for example to manage the different modes defined by the new regulations of the AFS type, and to optimize the service life of the lamp.
