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 vehicle lighting system receives power from a power supply and includes a lighting control module, a lamp, and a ballast having a bias control circuit. The lighting control module provides a remote enable signal to the ballast in response to an input. The bias control circuit of the ballast receives a supply voltage from a power supply and the remote enable signal and selectively energizes a bias regulator circuit of the ballast as a function of the remote enable signal. When the bias regulator circuit is energized, a controller of the ballast operates the ballast to provide power from the power supply to the lamp.

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.

Abstract: Zinc coated steel strip is produced by passing a strip through a molten zinc bath containing from 0.15% to 0.18% aluminum, controlling zinc coating weights to produce a relatively light coating of 0.20 oz./sq.ft. maximum on one side and a relatively heavy coating of 0.20 oz./sq.ft. minimum in the other side, and then uniformly heating both sides for a time and temperature sufficient to completely form an iron-zinc alloy on the light coated side and yet retain the essentially unalloyed zinc coating on the heavy coated side.
