- a single-pin fluorescent lamp with only a single pin as well as with a two-pin fluorescent lamp a special rotary socket, which these two pins Shorting in the socket is preheating the electrodes not allowed and also not technically possible.
- preheatable electrodes are an ignition source for flammable gases that would cause explosions of the surrounding atmosphere when the vitreous breaks Fluorescent lamp could lead.
- the safe ignition will in such lights because of the lack of preheating compensated by a higher starting voltage.
- the resonant circuit according to EP 0 257 600 B1 a capacitor parallel to the fluorescent lamp, and the Parallel connection of the capacitor with the fluorescent lamp is a choke and a coupling capacitor (in the patent with L1 or C11) connected upstream; in the execution according to EP 0 257 600 B1 must a lamp fuse should be provided for the lamp.
- the object of the invention is an electronic ballast of the type mentioned at the beginning, which complies with and complies with explosion protection regulations the familiar in the function and mode of action and significantly improved in particular with regard to security has been.

- a resistor the current limit of the current flowing to the base.
- these resistors warmed. Accordingly, according to claim 3 one of these resistors a temperature sensitive fuse in the form of a PTC thermistor or a temperature fuse assigned.
- this resistance carries too high a current, it leads that to a heating of the resistance, and with one Inadmissibly high heating increases the resistance value the PTC thermistor or releases the temperature fuse and interrupts the control to the controllable Switches so that the lamp current is switched off. If a double ballast is provided, only one Branch broken and the other branch can be normal continue working. If a PTC thermistor is provided, can after replacing the defective fluorescent lamp, the defective one Continue branching normally.

- the fuse F 3 is thermally and spatially assigned to the controllable switches V 25 and V 26 , as indicated by the broken line 23 and the edges 21 and 22.
- the fuse F 3 is assigned to the cooling vanes of the controllable Schlater V 25 , V 26 .
- Mains voltage is present at the network terminals L, N.
- the mains voltage is filtered in the harmonic filter formed from the inductor L 4 and the capacitor C 1 , rectified in the rectifier circuit V 1 and sieved through the capacitor C 12 , which is designed as an electrolytic capacitor.
- the capacitor C 5 charges via the resistors R 1 and R 21 .
- the diac V 7 switches through and outputs a current pulse limited by the resistor R 4 on the basis of the controllable switch V 26 , which is designed as a transistor, so that it becomes briefly conductive.
- the capacitor C 9 had previously been charged to the rectified mains voltage via the resistors R 17 and R 12 . Due to the short-term conduction of the transistor V 26 , the resonant circuit 13, which contains the inductance or the limiting inductor L 1 and the capacitance C 10 , is triggered from the capacitor C 9 with the aid of the capacitor charging.
- the limiting inductor L 1 has the control windings L 11 and L 12 , which are switched when the resonant circuit vibrations begin so that the transistors V 26 , V 25 alternately become conductive. As a result, the circuit continues to oscillate independently and, owing to the high resonance voltage at the capacitor C 10 , the fluorescent lamp 10 is ignited. The lamp current is limited by the limiting choke L 1 .
- the reactive current from the limiting choke L 1 flows back to the capacitor C 12 via the diodes V 13 , V 19 .
- the diodes V 12 and V 18 prevent the inverse operation of the transistors V 25 and V 26, respectively. If the resonant circuit vibrates, then further control signals are suppressed since the capacitor C 5 is continuously discharged via the diode V 6 in time with the oscillation frequency.
- the voltage coming from the limiting choke L 1 results in a current through the inductance L 3 , the resistors R 15 and R 16 into the base of the transistor V 26 .
- the voltage drop across resistor R 16 charges capacitor C 14 , which is limited by Zener diode V 17 to a voltage value which is approximately 5.6 volts.
- the capacitor C 8 charges via the resistors R 64 , R 15 , R 14 and R 65 .
- the transistor V 27 becomes conductive and, with the aid of the capacitor charge of the capacitor C 14 , switches a negative voltage to the base of the transistor V 26 , which changes into the blocking state, as a result of which the voltage direction at the Inductor L 1 reverses, so that the winding of the limiting inductor switches a positive voltage, which then controls the other transistor V 25 in the conductive state.
- the resistors R 11 and R 14 are wire jumpers and are used to adjust the power of the electronic ballast. If the output power is too low, the wire bridges are severed, as a result of which the charging time of the capacitor C 8 is increased and the frequency is reduced. This results in a higher output current or a higher output power of the electronic ballast.
- the capacitor C 15 charges via the diode V 21 , the diode V 22 and the resistor R 18 . After about three seconds, a voltage of 32 volts is reached, so that the diac breaks through V 23 and a current pulse flows, which flows through the resistor R 19 into the gate of the thyristor V 8 , which is turned on and through the resistor R 3 and the diode V 5 switches the transistor V 25 into the blocking state. As a result, the converter is switched off, thereby avoiding an impermissibly long voltage load on the lines coming from the ballast.
- the holding current for the thyristor V 8 supplies the rectified mains voltage via the resistor R 2 . After briefly interrupting the terminals L, N, the device is ready to start again.
- the voltage time area of the bre limiting choke L 1 on the control windings L 11 and L 12 is measured with the aid of an integration element which consists of the two components, the resistor R 64 and the capacitor C 8 , is composed, measured.
- the result is that when the DC voltage increases due to the higher mains voltage, the transistor V 26 is switched off earlier. A relatively stable oscillation frequency of the transducer is thus achieved.
- the Zener diodes V 2 , V 3 and the resistor R 6 serve as a further measure for stabilizing the lamp and thus also the luminous flux. If the Zener voltage is exceeded, an additional current flows into the capacitor C 8 . As a result, transistor V 27 becomes more conductive and switches transistor V 26 off earlier. In the control circuit of the transistor V 25 , the diode V 4 , V 30 and the resistor R 8 do this. As a result, the oscillation frequency changes as the input voltage increases, which means that the lamp current remains relatively stable.
- the switched between the fuse F 1 and the inductance L 4 fuse F 3 is connected in accordance with thermally-spatially the line of action 23 to the controllable switches V 25 and V 26, so that heating of the two control switches V 25 and V 26 leads to the fuse responding.
- a temperature-limiting element F 4 which can also be either a fuse or a PTC thermistor, so that the controllable switch V 25 is switched off.
- the capacitor C 11 which is designed according to the invention as a safe capacitor and thus as a film capacitor, helps to make the resonance circuit 13 safe, so that a fuse, such as is present in the ballast according to EP 0 257 600 A1, can be omitted .
