H05B 41/288 - Circuit arrangements in which the lamp is fed by power derived from DC by means of a converter, e.g. by high-voltage DC using static converters with semiconductor devices and specially adapted for lamps without preheating electrodes, e.g. for high-intensity discharge lamps, high-pressure mercury or sodium lamps or low-pressure sodium lamps
Disclosed is a position sensor, in particular a rotor position sensor, comprising a base. A track that is provided with a conducting coating is formed within the surface of the base relevant for evaluating signals. Since the track is formed within the base, the desired position-dependent modulation of the eddy current behavior is obtained by design measures, resulting in low manufacturing tolerance and reduced production costs.

HOUSING FOR AN IGNITION TRANSFORMER, TRANSFORMER DEVICE AND BALLAST ELECTRONICS FOR A GAS DISCHARGE LAMP
A housing for an ignition transformer for a gas discharge lamp comprises a cavity designed for accommodating the ignition transformer. The cavity has an opening for inserting the ignition transformer into the housing. The housing additionally comprises a primary voltage connection, which has two primary voltage contacts arranged such that they can be soldered to a printed circuit board arranged parallel to a first side of the housing. In addition, the housing comprises a high-voltage connection, which is situated on a second side of the housing, said second side being different from the first side, and has two high-voltage contacts, each of which can be connected to a plug. The primary voltage contacts and the high-voltage contacts are fed through a wall of the cavity into the cavity and can be connected to the ignition transformer.
