Definitions

  • the invention relates to a driver circuit and a method for controlling a dimmable lamp path.
  • the driver circuit supplies the lamp section, in particular an LED section with at least one LED, directly or indirectly electrically and permits the dimming of a lamp section connected or connectable to the driver circuit via a dimming area.
  • the lamp path is also to be understood as meaning at least one LED module which, in addition to the lamp, has further components such as a memory and / or a communication interface.
  • the illuminant path can also have one or more OLEDs.
  • the US 2012/0086701 A1 shows a dimming control for LEDs with combined digital modulation.
  • dimming by means of amplitude modulation takes place until a certain dimming level is reached, at which the amplitude is kept constant. Then switching to dimming using PWM modulation takes place in order to dim to dimming values below the specific dimming level, ie if, for example, a low dimming level is required.
  • the transition point between analog and PWM dimming i.e. the transition dimming value or dimming level at which switching from dimming to PWM dimming by means of amplitude change, advantageously depends on the design of the illuminant or the specific one Intended use should be discontinued.
  • the invention therefore proposes a driver circuit with an adjustable transition dimming value.
  • a method for operating an LED line is also disclosed.
  • the driver circuit and the method are the subject of the independent claims. Further developments of the invention are the subject of the dependent claims.
  • a system is provided with a driver circuit for the operation of an LED section which can be supplied by the driver circuit and is dimmable via a dimming range, the driver circuit being designed in such a way that the dimming range has at least a first range in which the dimming by means of amplitude change of the LED Current is carried out, and a second area which does not overlap the first area, in which the dimming is additionally or alternatively carried out by means of pulsed modulation, preferably PWM modulation, of the LED current, the second area lying below adjacent to the first area, and wherein a dimming value at which the transition from the first area to the second area takes place is adjustable.
  • the adjustable dimming value is also referred to below as the transition dimming value.
  • the driver circuit detects at least one test dimming curve using a connected sensor, e.g. by recording emission properties of the LED line over a certain period of time, and based on this, determine and set the adjustable dimming value.
  • the driver circuit can furthermore have an evaluation circuit that is functionally connected to it and that is used to evaluate recorded data / parameters.
  • the driver circuit can, in particular when there is a dynamic change in a predetermined dimming value to which the LED section is to be dimmed, the LED section in a limited range around the adjustable dimming value and / or for a limited period of time Combination of dimming by changing the amplitude and dimming by PWM modulation.
  • the driver circuit can set the adjustable dimming value depending on the LED path operated by the driver circuit.
  • the LED path can have at least one OLED.
  • the driver circuit can have a sensor interface, in particular for a connection to a photo sensor and / or a temperature sensor.
  • the driver circuit can be based on a direct, in particular by retrieving the information from the LED path, e.g. set the adjustable dimming value by accessing a memory, determined information and / or indirect information, in particular determined by acquiring parameters.
  • the driver circuit can use the information determined to determine the type of LED path to be operated and, depending on this, set the adjustable dimming value.
  • the driver circuit can store the at least one recorded test dimming curve in a memory which is functionally connected to the driver circuit.
  • an amplitude value can decrease towards the adjustable dimming value, and the dimming below the adjustable dimming value can be done using PWM modulation, preferably with the smallest one with respect to the adjustable dimming value Amplitude value and preferably with constant timing.
  • the driver circuit can communicate with the LED line via a communication interface.
  • the driver circuit can have a memory, in particular a look-up table, in which at least one adjustable dimming value, e.g. is stored in association with information about the LED path and / or parameters, and wherein the driver circuit can set the adjustable dimming value based on the direct and / or indirect information, and in particular can call it up from the memory.
  • a memory in particular a look-up table, in which at least one adjustable dimming value, e.g. is stored in association with information about the LED path and / or parameters, and wherein the driver circuit can set the adjustable dimming value based on the direct and / or indirect information, and in particular can call it up from the memory.
  • a method for the operation of an LED section which can be supplied by a driver circuit and dimmable over a dimming range, the driver circuit carrying out the dimming by changing the amplitude of the LED current in a first region of the dimming range and not in one with the first range overlapping second area carries out the dimming additionally or alternatively by means of PWM modulation of the LED current, the second area being below adjacent to the first area, and a dimming value at which the transition from the first area to the second area takes place can be set is.
  • the first and second areas do not overlap.
  • the driver circuit adjusts the adjustable dimming value at which the transition from the first to the second dimming range takes place, using a directly determined information and / or an indirectly determined information, the driver circuit detecting at least one test dimming curve by means of a connectable sensor and determining the adjustable dimming value based thereon and hires.
  • the dimming of the lamp path by changing the amplitude of the lamp current is also referred to as analog dimming or amplitude dimming, while the dimming by means of pulse width modulation of the lamp current is also referred to as PWM dimming.
  • the adjustable dimming value or the transition dimming value can be set depending on various criteria.
  • dimming values that are above the transition dimming value a purely analog dimming takes place, while in the lower range, i.e. Pure PWM dimming takes place below the transition dimming value.
  • dynamic dimming it may happen that the dimming methods overlap, in particular at the transition dimming value, or in a limited range around the transition dimming value or for a limited time.
  • the lowest, constantly clocked amplitude value can be selected, that is to say the amplitude value which is assumed for the transition dimming value when the amplitude is dimmed (ie the Amplitude value which results when a dimming value approaches the transition dimming value when dimming with an amplitude change).
  • One possibility is to provide a user interface on the driver circuit, for example a controller that is accessible to a user and via which the transition dimming value can be determined.
  • the dimming value can also be set on the production side, for example depending on a customer-specific application.
  • the driver circuit captures information and, depending on this, sets the transition value accordingly during operation or when connecting an illuminant path.
  • the driver circuit can be designed such that it can call up information from the lamp path, e.g. by accessing a memory of the lamp path, which in particular identifies the type and / or configuration of the lamp. This information is referred to as direct information in the following, since the driver circuit accesses the illuminant path directly.
  • the driver circuit can, however, also be designed to indirectly determine information and thus to infer the type of the connected illuminants or ambient conditions.
  • the driver circuit can thus be set up to detect electrical parameters of the lamp path and / or evaluate.
  • the driver circuit can use an integrated circuit (IC, ASIC) which is functionally connected to the driver circuit for evaluations.
  • IC integrated circuit
  • ASIC integrated circuit
  • the type / configuration of the lamp path to be operated can be inferred on the basis of the recorded electrical parameters or based on their evaluation.
  • environmental parameters can be detected and included, for example, using additionally or alternatively provided sensors, for example temperature or photo sensors. The detected and / or evaluated electrical and / or environmental parameters are referred to below as indirect information.
  • the driver circuit can then set the transition dimming value.
  • the driver circuit can also access a memory assigned to it, in which data for setting the transition dimming value are stored.
  • a transition dimming value associated with this can be selected on the basis of a look-up table and on the basis of the information.
  • at least one function can also be stored in the memory assigned to the driver circuit, so that a transition dimming value is determined functionally as a function of the detected information.
  • the driver circuit can therefore also have a sensor interface, via which it can be connected to a temperature and / or a photo sensor, in particular to record or measure test dimming curves. This can be done in a Configuration phase of the driver circuit or at the factory under conditions that simulate those that will prevail during later use. This can also be adapted to certain lamps. It can also be provided that the configuration phase is initiated again manually or automatically, for example in order to adapt to changed environmental conditions and / or lamps. The latter can also occur without replacement, for example due to signs of aging in the lamps.
  • Measurements can thus be made by the driver circuit in which the driver circuit detects light properties of the illuminant path as a function of various dimming values and determines an optimal transition dimming value from analog dimming to PWM dimming on the basis of the detected properties or the behavior of the illuminant path.
  • the driver circuit is also able to distinguish different lamp paths based on their electrical properties.
  • a lamp path with LED lamps can thus be distinguished from a lamp path with OLED lamps, since the electrical characteristics of OLEDs and LEDs are different.
  • a color change is more pronounced with an analog dimming of OLEDs than with an analog dimming of LEDs.
  • the transition dimming value is therefore chosen differently than when operating a lamp path with only LEDs.
  • the transition dimming value is then included OLEDs, in particular, are higher than when an illuminant section is operated with only LEDs.
  • the adjustable transition dimming value can be set on the basis of a signal / command that is supplied to the driver circuit.
  • a dimming value can be set for the driver circuit via its electrical supply, for example by supplying a supply voltage of alternating and / or different polarity, or by means of a switch-on / switch-off sequence.
  • the signal can also be supplied via a bus interface.
  • a bus interface of the driver circuit can preferably be connected to a DALI or DSI bus.
  • the driver circuit can also use the bus interface to inform other bus participants, for example, of the set or adjustable transitional dimming value. It is thus possible, for example, for the driver circuit to determine information and data which are relevant for setting the transition dimming value by means of measurements and / or sensory detection. If the transition dimming value is determined by the driver circuit, the driver circuit can transmit this transition dimming value to be set to other driver circuits which, for example, do not have the possibility of acquiring / determining the corresponding information or data, that is to say, for example, do not have a sensor interface.
  • the dimming methods are mixed at the adjustable switchover dimming value for a limited period or within a limited range.
  • the Fig. 1 shows two examples in which the transition dimming value is changed by the driver circuit.
  • the transition dimming value on the one hand to x% ( Fig. 1 left) or on the other hand to a higher dimming value y% ( Fig. 1 right) can be set in order to set the ranges of the dimming using PWM modulation (PWM) or amplitude modulation (AM).
  • PWM PWM modulation
  • AM amplitude modulation
  • dimming can also be carried out, for example, only by changing the amplitude or exclusively by means of PWM dimming. This is the case if the transition dimming value is set to zero percent (0%) or a minimum dimming value (e.g. 5%) or to 100 percent (100%) or a maximum dimming value (e.g. 80% - 95%). In the first case, dimming can then only be carried out by changing the amplitude, in the second case only using pulse width modulation, or vice versa. As said, the transition dimming value can be set by a user or based on the connected illuminant.
  • Fig. 2 shows an example of how the driver circuit TS supplies the lamp path LM on the one hand, but on the other hand additionally data D with the Can replace the lamp path.
  • the lamp path has a memory S which contains information about the lamp path.
  • the driver circuit TS thus directly acquires information about the lamp path LM in order to set the adjustable transition dimming value accordingly.
  • a bus interface bus and a sensor interface Sens are also shown schematically on the driver circuit, as is an optional memory TSS associated with the driver circuit.
  • the illuminant path LM can also have a coded plug or a coded socket for connection to the driver circuit or an operating device having the driver circuit, the driver circuit then being able to recognize the type of illuminant path depending on the plug / socket.
  • bidirectional communication can take place between the driver circuit TS and the lamp section LM, so that the driver circuit TS can change or adapt parameters of the lamp section LM, for example.
  • the communication between driver circuit TS and lamp path LM can of course take place either analog or digital. Communication via a separate communication interface to driver circuit TS and / or illuminant path LM is, however, not absolutely necessary, since communication via supply V can also take place, for example by modulating the supply parameters.
  • FIG. 3 Another exemplary embodiment is exemplary in Fig. 3 shown, in which the driver circuit TS only communicates with the lamp path via the supply V.
  • the driver circuit TS points in Fig. 3 a detection circuit / detection circuit, which can be provided in addition or as an alternative to components of the driver circuit TS already described.
  • This detection circuit is preferably set up to detect electrical parameters, such as current or voltage parameters or capacitance values, which are used directly or indirectly to supply V to the lamp path LM.
  • the parameters can also be recorded continuously, so that when the illuminant path changes, for example due to signs of aging, and a resultant change in the electrical parameters of the illuminant path LM and / or when the ambient parameters change, the transition dimming value can be changed.
  • the leakage current can also be measured as an electrical parameter if OLEDs are used as the illuminant of the illuminant path.
  • the adjustable transition dimming value can be set in that the driver circuit TS detects or monitors saturation of the LEDs and detects them by their measurement. At which dimming value the colored LEDs no longer conduct / are no longer active.
  • the driver circuit TS can also use the optional photo sensor use. The driver circuit can then set the adjustable transition dimming value in such a way that it lies above the dimming value at which the colored LEDs no longer conduct, so that dimming takes place below this dimming value only with PWM modulation.
  • pulsed modulation As an alternative to PWM modulation, other types of pulsed modulation can also be used according to the invention, for example pulse duration modulation or pulse code modulation.
