Definitions
- the invention relates to a method and a ballast for operating a lamp provided with a fluorescent lamp.
- ballasts are known from EP 0 889 675 A1, with which several different types of lamps of fluorescent lamps be operated under optimized operating conditions can. The degree that can be achieved with these ballasts Optimizing the operating conditions of a fluorescent lamp however leaves something to be desired.
- ballasts according to EP 0 889 675 A1 sees one Preheat phase of the electrodes. It is a ballast for warm started fluorescent lamps. At a such are those at the ends of the discharge tube Fluorescent lamp preheated in the tube protruding electrodes. In doing so, they encounter those with an emitter material Electrodes ion out, causing the contained in the discharge tube Gas filling becomes electrically conductive. Only after this The so-called discharge path of the fluorescent lamp becomes the preheating phase by ignited. With this procedure spared the electrodes. During the preheating phase, the electrode resistance of the fluorescent lamp measured, to indirectly infer the electrode temperature and perform the preheating carefully.
- the measured Electrode resistance to the lamp type of the fluorescent lamp getting closed The fluorescent lamp is initially with a low power supply and the electrode temperature measured indirectly. If the initial current is not enough to to heat the electrodes to an expected temperature, so the current is increased in stages until the electrode resistance repectively the expected electrode temperature has been reached.
- the electrode resistance is not clear criterion for differentiating the lamp types. Optimal operating conditions can be achieved with the known ballast can only be set if the lamp types to be recognized are only those whose electrode resistances differ significantly.
- ballast known from EP 0 889 675 A1 is used to determine the lamp type of the fluorescent lamp instead of the more complex measurement of the electrode resistance the simple procedure of lamp voltage measurement applied. Since the indirectly to be carried out via the electrode resistance This measurement is effective if temperature measurement is saved back to the simple procedure of lamp voltage measurement. due to the lack of optimized preheating, the Electrodes of the fluorescent lamp in this ballast increased wear. Furthermore, different Lamp types when they are the same or close to each other Have lamp voltages, also not clear be distinguished. Also the setting of optimal operating conditions is only possible with this ballast if the lamp types to be recognized are such deals, the lamp voltages differ significantly.
- the Circuit also includes a measured value evaluator, a lamp voltage measuring device as well as a DC voltage generator, with which a logic voltage can be generated.
- EP 0 759 686 describes a method and a circuit arrangement for operating an electric lamp of a predeterminable Lamp type disclosed.
- the procedure shows the steps the detection of a lamp which indicates the lamp type of the lamp first information and the step of driving the lamp in Dependence of the lamp type-specific first information.
- This initial information can be provided by a sensor that has an individual lamp type Operating state detected, or by a Input device must be specified.
- the invention is therefore based on the task of a simple one Method and a ballast for performing the method to propose a variety of common Lamp types of fluorescent lamps under a higher one Have the degree of optimization run.
- the object is achieved by a method for operating a lamp provided with a fluorescent lamp, the operating data of certain recognizable lamp types at least their nominal lamp voltage, the nominal lamp current and Preheating currents and preheating times for heating the electrodes in are stored in a register, the preheating currents being predetermined Assigned areas of the electrode resistance are the electrode resistance during a preheating phase measured and the associated with the measured electrode resistance Preheating current and the assigned preheating time set the fluorescent lamp within one of the preheating phase downstream start phase for a predetermined time is operated with a dimming current of known amperage after the present phase of the lamp voltage of the fluorescent lamp is measured, then that nominal lamp voltage in the register is searched for, the measured lamp voltage comes closest to the fluorescent lamp, and then the one for Operation of the fluorescent lamp required operating data can be set which corresponds to the measured lamp voltage per Registers are assigned.
- the lamp type recognition of the present invention is based on the principle of lamp voltage measurement during the start phase the fluorescent lamp. In addition, however, comes the knowledge of Electrode resistance due to the pre-heating phase has been determined and another selection criterion to determine the exact lamp type. With the invention The process is thus an electrode-sparing Warm start of the fluorescent lamp made and also a enables precise determination of the lamp type.
- the invention also includes the possibility of operating data to be able to change and adjust the fluorescent lamp directly or indirectly via sizes legally linked to them to be able to adjust.
- the dimming current and the lamp current for example can be changed by changing the AC frequency adjust that applied to the fluorescent lamp during operation is.
- a predetermined operating time should be can be understood, which range from a few seconds to a few minutes can.
- the dimming current set at the start of the start phase corresponds the lowest nominal lamp current stored in the register or is bigger than this. It corresponds to the least of the saved ones Nominal lamp currents, a fluorescent lamp can with low nominal lamp current even after long-term operation these conditions are not overloaded. Since the start phase but it only takes a few seconds to minutes, failure too not such fluorescent lamps whose nominal lamp currents are lower are than the dimming current.
- an optimized one is made during the starting phase Dimming current set, its amperage for operation a fluorescent lamp is sufficient, the nominal lamp current is higher than the optimized dimming current and a fluorescent lamp is not destroyed, the lamp nominal current is lower than the optimized dimming current.
- the optimized dimming current provides sufficient Energy to generate sufficient light intensity.
- a dimming setting from a few seconds to a few minutes can be accepted as there is sufficient brightness is achieved.
- Preheating phase at the beginning of a first stage the lowest in Stored preheating current set after the first Preheating stage with a first YES / NO query checks whether the electrode resistance in one of the predetermined Ranges of electrode resistance falls, and at a YES decision a further stage of the preheating phase triggered, maintaining the preheating current of the previous stage and then the start phase is initiated.
- a NO decision triggers another stage of the preheating phase, at the beginning of this stage the next higher one in the register stored preheating current set and either after a predetermined time initiated the start phase or another YES / NO query is performed using the same process steps as follows after the first YES / NO query.
- each YES decision triggers a further stage of the preheating phase, whereby the preheating current of the previous preheating stage is maintained. Every NO decision triggers another stage in the preheating phase with the next higher preheating current.
- the last one in Process flow provided YES / NO query triggers if it if the decision is NO, an increase in the preheating current is selected and then after a predetermined time the start phase without a another YES / NO query is carried out.
- a further improvement in the process is achieved if the stored operating data of the recognizable lamp types in the register are divided into lamp groups, with inside only one fluorescent lamp with different lamps Nominal lamp voltages are included that each lamp group by registering one of the areas of the electrode resistances and a preheating current is assigned that over the determined Electrode resistance or the last one during the preheating phase set is determined, which group of lamps the fluorescent lamp belongs to that during the subsequent start phase within the determined Lamp group of the register searched for the nominal lamp voltage is that of the measured lamp voltage of the fluorescent lamp comes closest, and then the one to operate the Fluorescent lamp required operating data set are assigned to the measured lamp voltage via register are.
- start-up phase can also be summarized the recognizable lamp types in lamp groups can be improved.
- Each lamp group in the register has a dimming current for this assigned, the one to be set for the start phase Dimming current during the preheating phase due to the detection the lamp group.
- the process sequence is an advantageous further development a three-stage preheating phase with two possible YES / NO queries before, a NO decision of the second YES / NO query triggers the third stage of the preheating phase, whereby compared to the previous stage of the preheating phase highest preheating current stored in the register and the start phase is initiated after a predetermined time.
- the three-stage process sequence offers three specified preheating currents, the, starting with the least, in consecutive Stages of the preheating phase can be increased.
- the three-stage process for preheating is an advantageous one Compromise with which to preheat the multitude of Lamp types is sufficiently differentiated and the design effort for the required ballast in one reasonable framework.
- Lamp voltage can be stored in the register. While the operation of the fluorescent lamp is then checked whether the lamp voltage present in operation the maximum Lamp voltage exceeds. If the maximum lamp voltage then a safety shutdown the fluorescent lamp. Checking the lamp voltage can, for example, take place continuously or in predetermined Time intervals are carried out.
- a minimum lamp voltage in the register can also be analog be saved and checked whether the present Lamp voltage falls below the minimum. In the event of a shortfall turn off the fluorescent lamp performed.
- the stored maximum lamp voltage is expediently above the highest of the lamp voltages stored in the register. Alternatively, for each individual or for Groups of lamp types have different maximum lamp voltages be saved.
- the start phase is assigned by actuating one of the lights ON / OFF switch carried out or useful when the lamp is switched on by inserting a Fluorescent lamp inserted into an empty lamp holder. On this prevents one from being on fluorescent lamp put into operation with the lamp incorrect operating data is operated. The same applies the preheating phase. This can also be done by pressing ON / OFF switch or by inserting a fluorescent lamp lead into an empty lamp holder.
- the invention also consists in a particularly simple one Design of a ballast for performing the inventive method, with a frequency generator and a control circuit which cooperates with this and which Fluorescent lamp over power transistors with an AC voltage supplied, the lamp current through a limiter is adjustable, a register in which the operating data several lamp types are registered, a sequence control which the timing of the during a start phase of Controls fluorescent lamp process steps to be carried out, a measured value evaluator, a lamp voltage measuring device and a DC voltage generator with which a logic voltage can be generated.
- the lamp current can z. B. indirectly via the frequency the AC voltage, by changing the DC voltage or can be adjusted by changing impedances.
- ballast is advantageous. Its construction allows only the control circuit as well as the downstream power transistors by the DC generator with high energy supply to operate the fluorescent lamp.
