Abstract: The invention relates to a base for a high-pressure discharge lamp comprising a transformer (300) that is disposed in a chamber (214) of the base (2). Sealing compound (6) is arranged in the interstice between the transformer (300) and the walls of said chamber (214). The terminal (301) of the secondary winding of the transformer (300), which is designed for high voltages, is embedded in the sealing compound (6). According to the invention, only some of the interstice is filled with the sealing compound (6).

Abstract: A circuit arrangement has a first input terminal for a first voltage potential; a second input terminal for a second voltage potential; a third input terminal for feeding a starting voltage; a first electrical connection, which provides at its first end a first output terminal for a high-pressure discharge lamp, and which is coupled at its second end to the first input terminal for the first voltage potential; a second electrical connection, which provides at its first end a second output terminal for a high-pressure discharge lamp, and which is coupled at its second end to the second input terminal for the second voltage potential; a first inductor arranged in the second electrical connection; and a starting device coupled on the input side at least to the third input terminal for feeding a starting voltage, and on the output side to one of the output terminals, and a second inductor together with a first inductor.
