    摘要： The invention relates to a ballast for at least one gas-discharge lamp, having a load circuit, to which the gas-discharge lamp is to be connected, a preferably switched-mode heating circuit controlled by means of a switch for at least one coil of the gas-discharge lamp, and a control circuit, wherein the control circuit directly or indirectly detects a temperature of at least one coil on the basis of a preferably electrical temperature parameter, such as for example, a voltage and/or a current at the at least one coil, and the control circuit uses the determined temperature parameter as an actual value for a control of a heat output in order to control the electrical heat output supplied to the coil according to the temperature parameter by activating, preferably pulsing, the switch of the heating circuit. The invention further relates to a method for controlling a coil voltage of a gas-discharge lamp and to a circuit for carrying out the method.

    摘要： The invention relates to a method and to an operating device for operating a lighting means (61), wherein the current flowing through the lighting means (61) is regulated. The lighting means (61) is provided with an alternating power output from an inverter (4). To regulate the current, a measurement signal UL is generated which corresponds to the voltage across the lighting means (61), said signal being sent to the control circuit section (7). The power output from the inverter (4) to the lighting means (61) is measured in the form of a measurement signal PI which drops across a shunt resistor (43) and is fed to the control circuit section (7). The control circuit section (7) determines the actual value of the current flowing through the lighting means (61) from the power and from the voltage drop across the lighting means (61), and compares said value with a current setpoint. The control circuit section (7) generates clock signals for the electronic switches (41, 42) of the inverter as a control value.
