Definitions

  • the present invention relates to an operating circuit for a low-pressure discharge lamp. It deals specifically with the behavior of one Low pressure discharge lamp immediately after the discharge ignition in a start-up phase and with a start-up circuit adapted to this behavior.
  • German patent 195 46 588.1 A practicable way is shown in the German patent 195 46 588.1. There is the described difficulty with the start-up behavior of a mercury-containing one Low pressure discharge lamp has been tackled by increasing the lamp current setpoint of a lamp current regulating in operation Control IC during the start-up phase. For further details reference is made to the document.
  • the invention is based on the technical problem of an operating circuit according to the preamble of claim 1 with regard to an improved To further develop reliability and improved operating characteristics.
  • a circuit for operation a low-pressure discharge lamp with a start-up circuit for Lamp current control during a start-up phase characterized in that that the starting circuit is a sensor device for one of the luminous flux or the temperature of the lamp dependent size and the Lamp current depends on the luminous flux or the temperature of the lamp controls.
  • the invention therefore provides for the lamp current to be dependent on the start-up phase to be controlled by a measurement parameter that indicates the operating state characterized the lamp.
  • a deviating from the continuous operating state Operating state that currently characterizes the start-up phase a Lamp current control that result in a luminous flux in the Continuous operating state results in at least approximate luminous flux of the lamp.
  • the operating status can be recognized in the start-up phase via a lamp temperature that deviates from the continuous operating temperature of the lamp or one that does not correspond to the desired continuous luminous flux Luminous flux.
  • the startup behavior described above of mercury-containing low-pressure discharge lamps requires one too low lamp temperature a too low luminous flux, what about a Increase in the lamp current in the start-up phase can be compensated can.
  • the present invention gives way to the characterizing part of claim 1 accordingly - from the concept of the document cited above in that the lamp current control from a measurement parameter depends on the luminous flux or the lamp temperature.
  • the lamp current control from a measurement parameter depends on the luminous flux or the lamp temperature.
  • the described prior art is namely one in the circuit design adjustable time period for a fixed lamp current increase is also used.
  • the increased lamp current is approached via a continuous ramp and returned at the end of the given time; however, that is Entire schedule of times for start-up, stop and return of the excessive lamp current and for the degree of excessive in the Sense of current regardless of the actual operating condition of the Lamp fixed and unchangeable in individual cases.
  • this Rigid "lamp current control not only leads to a relatively poor adaptation of the luminous flux in the start-up phase.
  • the rigidly specified increase in lamp current can lead to damage to the lamp or the operating circuit each time the lamp is started. For example, a restart of a mercury-containing low-pressure discharge lamp After a brief interruption in operation, the lamp is still warm. The operating temperature can now rise above the setpoint temperature for continuous operation, so that the luminous flux of the lamp is reduced again by the too high mercury vapor pressure.
  • the start-up circuit achieves exactly this for this case
  • the excessive temperature also accelerates the aging and thus the probability of failure of the lamp and the electronic components in its immediate vicinity.
  • An analogous reasoning also applies to the increase due to the excessive lamp current temperature of the operating circuit, even if it is not arranged directly next to the lamp.
  • the lamp current control and in the example described made the lamp current increase dependent from the measurement parameter characterizing the operating state of the lamp. Accordingly, the lamp current control can be relative, according to duration Elevation or humiliation or by sign and after activation or deactivation can be controlled.
  • one or more measurement parameters which are either the luminous flux of the Label the lamp or the lamp temperature directly or indirectly.
  • a temperature sensor is provided which is not directly the lamp temperature but one of the lamp temperature dependent temperature measures. This affects e.g. B. measuring points in the lamp base and / or in the operational circuit or at other points that are thermally coupled to the lamp. In a special case it is one Temperature sensor integrated with a control IC of the operating circuit executed. Control ICs are preferred in this invention because the Combination with a control circuit in the operating circuit offers. Then the start-up circuit and the sensor device, i. H. the Temperature sensor, to be integrated in the IC.
  • a photodetector can be used, the luminous flux the lamp measures.
  • Luminous flux detection should take place via the photodetector at least in the case of discharge lamps containing mercury, preferably additionally for temperature detection. Otherwise an overheating operating condition cannot be safely distinguished from a cold start because the luminous flux with excessive Hg vapor pressure as well as with too low one Hg vapor pressure decreases.
  • the Measure the burning voltage of the lamp instead of the lamp luminous flux, the Measure the burning voltage of the lamp.
  • the lamp current control can be simple and effective Variant of the invention by changing the duration of a lamp current increase or decrease. happenss in the more complex case this together with a change in the current intensity, in simplest case, however. Deactivation can be done by zeroing or a very large reduction in the duration.
  • the necessary timer circuit on the one hand a combination of a clock and a counter with possible Change in the clock frequency or the final count that determines the time of the counter. It can also change the rank of the clock input in the Counters are changed so that the counter accordingly at a higher Digit counts and thus a value defining a time period earlier reached.
  • there is a combination of an RC element and a comparator in question again the time constant of the RC element and the threshold value of the comparator can be changed.
  • Another embodiment of the invention relates to that already mentioned above Temperature detection.
  • the desired measuring point can be the measuring point on one that generates heat independently of the lamp in lamp operation Component be arranged.
  • This component can e.g. B. part of the mentioned Control IC or the whole IC. But there are z. B. also power transistors an oscillator and similar heat-generating components on.
  • FIG. 2 The figure corresponds to FIG. 2 of the cited application and shows one Function block diagram of a control IC with one of the present Extension corresponding to the invention compared to the aforementioned FIG. 2 the earlier registration.
  • a new block TM for a temperature sensor inserted which detects the temperature of the silicon IC shown.
  • the block TM is via a new entrance ZE4 to the one already mentioned from the application known counter Z connected. Both blocks can be found in the Figure in the upper left corner.
  • the temperature sensor compares TM the measured value with a reference value in order to determine a digital signal, whose two possible values (1 or 0) for an IC temperature above or below the reference value. This digital signal is entered into the ZE4 input of the Z counter.
  • the counter Z reacts to the value of the signal from the temperature sensor TM in that the already known from the earlier application Clock generator TG predetermined clock pulses to count up the Counter Z at another position (in the sense of a multi-digit binary number) or with a different rank.
  • the clock pulses are therefore not on the least significant element but on a predetermined factor given higher value element.
  • the counter Z can consist, for example, of a chain of a number of flip-flops (eg 22) whose output frequency halves the input frequency in each case.
  • the main advantage of the solution according to the invention is that the the rest of the circuit remains technically completely unchanged, i.e. the other conventional ones Setpoint levels (shown in Figure 4a of the cited application) be run through so quickly that the start-up phase is practically eliminated.
