摘要： The invention relates to a circuit arrangement which is used to operate a low pressure discharge lamp (EL), wherein the discharge lamp receives power. Said circuit arrangement is embodied in such a manner that power-determination components (C2a, L2a) of the circuit arrangement are embodied in a temperature-dependent manner such that the power consumption of the lamp is limited when the temperature rises. Capacitors (C2a) and throttles (L2a) can be embodied in a temperature-dependent manner in a control circuit (AS) of the circuit arrangement.

摘要： The invention relates to an electronic ballast comprising a converter which is used to operate a discharge lamp, for example, a low pressure discharge lamp, for selectively operating, in a direct manner, the supply network or a phase section dimmer. Jumps in the supply voltage are decoupled by a differential which is connected between at least one of the network lines and the reference potential of the ballast and transmitted to a control of the ballast, such that the control of the converter can distinguish between the operation on the phase section dimmer and on the network supply.

摘要： The invention relates to a circuit which comprises a voltage-controlled transistor (T4) and is used to switch the same. Said circuit is embodied in such a way that the connection of a first transistor (T1) triggered by a control signal causes a first current to flow through a series connection (R4, T1) and starts to reload a control gate of the voltage-controlled transistor (T4). The first current passing through the series connection (R4, T1) causes a first potential shift at the connection node (V1). Said first potential shift switches on the second transistor (T2), thus causing a second current to flow through the contact gap of the second transistor (T2) into the control gate of the first transistor (T1), amplifying the first current. The increasing reloading of the control gate of the voltage-controlled transistor (T4) causes a second potential shift at the connection node (V1). The second transistor (T2) is switched off by said second potential shift, while the first transistor (T1) remains switched on and the voltage-controlled transistor (T4) is maintained in the new switching state thereof.

摘要： The invention relates to an electronic ballast presenting an input capacitor (C) and comprising and step-up chopper (LH, DH, SH, CH) for operating a load, for example a discharge lamp(CFL), on a phase control dimmer (DIM) having an integrated or parasite inductance (L). According to said invention, excessive voltage after connection with a phase control can be reduced by adjusting currents by means of the step-up chopper (LH, DH, SH, CH).
