- These dimmable control gears have one Control input that is used as a setpoint for brightness control Voltage can be applied.
- the control input is usually a 1-10V interface educated. In the simplest case, this control input is used Dimming potentiometer connected to the brightness of those operated on the control gear Set lamps to the desired value. With the help of the dimming potentiometer and with the help of one with a periodically changing voltage excited transformer, a voltage with a Value generated between 1V and 10V, which is the setpoint for the desired brightness setting represents.
- This voltage is applied by means of the transformer transmit an evaluation device in the operating device.
- the evaluation device generates with the help of a peak value rectifier the setting on the dimming potentiometer appropriate signal for controlling the lamp current or the power consumption the lamp or for controlling the output power of the control gear.

- the sample and hold element is advantageously part of an analog-digital converter trained to provide a digital control signal for a microcontroller or to generate an integrated circuit that serves to regulate the operating device.
- the transformer serving as a transformer advantageously has a first one Winding connected to the control input and at least one second Winding, which is connected to the evaluation device and magnetically the at least one first winding is coupled. This creates a galvanic Separation between the control input and the evaluation device guaranteed.
- an AND gate As a device for frequency adjustment of the sequence signal to the time periodically changing electrical voltage and to produce the constant time shift an AND gate is advantageously used. In this way any voltage spikes can be generated inexpensively and with simple means Hide the voltage transmitted by the transformer.
- the output voltage of the sample and hold element is advantageously used for control of the operating parameter of the at least one electric lamp or previously converted into a digital signal by means of an analog-digital converter.
- the embodiment of the invention shown in FIG. 1 is a dimmable control gear for a fluorescent lamp.
- the control gear has two mains voltage connections 1, 2 and a downstream DC voltage supply 3 for a half-bridge inverter 4.
- the DC voltage supply 3 usually contains a radio interference filter and a rectifier for the AC mains voltage. In addition, it can also have a harmonic filter in order to achieve the best possible To ensure sinusoidal mains current draw.
- the half-bridge inverter 4 comprises two alternating switching transistors 5, 6, two coupling capacitors 7, 8 and a half bridge branch designed as a series resonant circuit, the contains the choke 9, the capacitor 10 and the fluorescent lamp 11, the Discharge path of the fluorescent lamp 11 connected in parallel to the capacitor 10 is.
- the half-bridge inverter does not necessarily have to be a symmetrical half-bridge inverter 4 with two coupling capacitors 5, 6, but can instead also have only one coupling capacitor and thus as asymmetrical Half-bridge inverter should be designed.
- Transistors 5, 6 of the half-bridge inverter 4, which are preferably field effect transistors acts are controlled by a microcontroller 12.
- the microcontroller 12 generates pulse-width modulated signals that indicate the switching clock of the transistors 5, 6 determine and thereby a power control or brightness control enable the fluorescent lamp 11.
- the pulse width modulated signals for the transistors 5, 6 are dependent on the microcontroller 12 the DC voltage present at the connections 13, 14 of the control input is generated.
- the control input 13, 14 can have a DC voltage with values between 1 V and 10 V can be impressed.
- a transformer 15 is used to impress the control input 13, 14 Transfer voltage to an evaluation device 16.
- the Primary winding 15a of the transformer 15 via a rectifier diode 17 with the Control input 13, 14 connected, while the secondary winding 15b to the voltage input the evaluation device 16 is connected.
- Between the primary 15a and the secondary winding 15b of the transformer 15 is magnetic Coupling.
- Parallel to the control input 13, 14 and to the primary winding 15a an input capacitor 18 is connected. So that the transformer 15 the Control input 13, 14 impressed DC voltage to the evaluation device 16 can be transmitted, the transformer 15 is of a substantially rectangular shape Excitement. This, essentially rectangular voltage will generated by means of an oscillator 19 and a frequency divider 21 and via a Voltage divider resistor 20 applied to the secondary winding 15b.
- the evaluation device 16 therefore detects on the one connected to the secondary winding 15b Voltage input is a substantially rectangular voltage whose Amplitude is determined by the DC voltage impressed on the control input 13, 14 is.
- the evaluation device 16 provides with the microcontroller 12 connected voltage output a corresponding signal for the microcontroller 12 ready for power or brightness control of the fluorescent lamp 11.
- the evaluation device 16 has a sample and hold element 22, which is a component an analog-digital converter 23 is formed, and an AND gate 24. With With the aid of the sample-and-hold element 22 and the AND gate 24, those of the Stray inductance of the transformer 15 caused voltage peaks on the rising Flank of the rectangular voltage of the secondary winding 15b is hidden. This situation is explained in more detail below with reference to FIG. 2.
- Curve A in FIG. 2 shows the time course of the rectangular voltage U, which is used to excite the transformer 15.
- This rectangular Voltage is generated by means of the oscillator 19 and the frequency divider 21, which is a frequency halving causes, generated and via the resistor 20 to the secondary winding 15b. As has already been mentioned above, this will change in time periodically changing, exciting voltage needed to transmit the Control input 13, 14 impressed DC voltage through the transformer 15 enable.
- Curve B in FIG. 2 shows the time course of the on the secondary winding 15b and detected by the voltage input of the evaluation circuit 16 Voltage U.
- This voltage applied to the secondary winding 15b has the periodicity of the exciting voltage (curve A).
- Your amplitude - that means the height of the rectangular pulses - but is due to the value of the control input 13, 14 determined DC voltage.
- the sample-and-hold member 22 With the help of the sample-and-hold member 22, the disturbing Voltage pulses are hidden.
- the duration and the Start of the sequence signal (also called sample signal) of the sample-and-hold element 22 adapted to the voltage on the secondary winding 15b.
- Curve C in FIG. 2 shows the time course of the sequence signal of the sample-and-hold element 22.
- the duration of the sequence signal (curve C) is exactly half as long as a rectangular pulse of voltage (curve B) on the secondary winding 15b and that follow signal is in sync with the second half of the square wave voltage on the secondary winding 15b. This causes the disturbing voltage pulses hidden on the rising and falling edge of the square wave voltage.
- This tuning of the sequence signal to the voltage on the secondary winding 15b is by means of the frequency divider 21, which is designed as a JK flip-flop AND gate 24 and the oscillator 19 performed.
- the oscillator 19 generates both the voltage exciting the transformer 15 (curve A) and the follow signal (Curve C).
- the square-wave voltage generated by the oscillator 19 becomes on the one hand the first voltage input of the AND gate 24 and on the other hand fed to the voltage input of the frequency divider 21, which is a frequency halving of the square-wave voltage supplied to it.
- the one at the voltage output of the frequency divider 21 applied, frequency-halved square wave voltage on the one hand supplied to the second voltage input of the AND gate 24 and on the other hand applied to the secondary winding 15b via the voltage divider resistor 20, to excite the transformer 15.
- the output voltage of the AND gate 24 is supplied to the sample-and-hold element 22 as a sequence signal (curve C) for controlling the follow and hold signal (also called sample & hold signal) of the sample and hold member 22 is used.
- the sample-and-hold link signal 22 (curve C) is therefore synchronous to the second half of the rectangular pulse of the stimulating Voltage (curve A) and thus also in sync with the second half of the voltage pulse the voltage applied to the secondary winding 15b (curve B).
- the curve D in FIG. 2 shows the time course of the output voltage U des Sample-and-hold member 22, which is converted by the analog-digital converter 23 into a digital Signal for the microcontroller 12 for pulse-width modulated control of the transistors 5, 6 is converted.
- the output voltage of the sample and hold element 22 a DC voltage, the value of which only from that of the control input 13, 14 depends on the impressed DC voltage. Because of the losses in the sample and hold link 22 has the output voltage of the sample and hold element 22 (curve D) a ribbed structure.
- the oscillator 19 is identical to the half-bridge inverter 4.
- the sample and hold element 22, the analog-to-digital converter 23 and the AND gate 24 are preferably formed as part of the microcontroller 12.
- control input does not necessarily have to be an analog one Control input, which can be acted upon by a DC voltage.
- control input can also be designed as a digital control input, with digital signals for specifying a setpoint for brightness control the at least one lamp can be acted upon.
