Definitions
- Control device for transmitting control information to a lamp unit and method
- the invention relates to a control device for transmitting control information to at least one lamp having at least one lamp operated with alternating current lamp unit, which control device a switchable output stage, a power supply, a Null shedgangserken- tion device, a modulator for generating a modulation voltage for impressing the control information to that of the lamp unit ü over the control unit supplied AC voltage and a logic unit comprises. Furthermore, the invention relates to a method for determining the time of commencement of a modulation phase subsequent to an operating phase in which a lamp unit receives the energy necessary for its operation.
- Control devices and methods for driving lamp units are well known. It is thus known to drive a plurality of electrical structures, including lamp units, via a bus system.
- a bus system transmits signals in digital form, which are decoded by a processor assigned to the respective consumer, for example also a lamp unit, in order to control the power consumption or other properties of the respective consumer.
- a processor assigned to the respective consumer for example also a lamp unit
- control signals over the same line that is needed for the energy transfer for each consumer. This procedure requires that each consumer has a unique address.
- Such systems are not readily suitable for the operation of lamp units, for example in the living area, in which a simple change of the lamp unit must be possible. For the lighting of rooms, the requirement is frequently made to change or regulate the brightness of light sources.
- incandescent lamps dimmers are used for this purpose, which are usually designed as two-wire devices. Due to one opposite light bulbs different behavior of alternative light sources, such as gas discharge lamps, LEDs or OLEDs are suitable for incandescent dimmers only with considerable additional effort for dimming the aforementioned alternative light sources.
- DE 10 2009 051 968 describes a method for transmitting control information to a lamp unit, a suitable lighting system, a lamp unit and a control unit for this, with which method or devices also energy-saving lamps, especially in a two-wire application user-friendly and the electromagnetic Compatibility requirements can be operated accordingly.
- the method described in this document makes use of the property that alternative light sources, such as eg gas discharge lamps, ie: energy-saving lamps, only pick up the energy necessary for their operation over a certain section of a half-wave.
- the portions of a half-wave not used for such an operating energy input of the lamp unit are used for the power supply of the control unit upstream of the lamp unit and for the transmission of the control information from the control unit to the lamp unit.
- the transmission of the control information is effected by impressing a modulation voltage in the manner of a digital signal on such a part of the half-wave in which the lamp unit receives no operating energy.
- a power supply of the control unit takes place in a first part of each half-wave before the lamp unit starts with its operating energy consumption, while control information is transmitted in the last part of each half-wave. This can basically be provided in reverse order.
- the phase of the transmission of the control information is referred to as modulation phase in the context of this embodiment.
- the phase of each half cycle in which the lamp unit receives the energy necessary for its operation is addressed as the operating phase.
- control device in which this has a switchable parallel branch, via which, when switched, an impedance can be added, which is greater than the impedance of the output stage, the parallel branch, when switched, a shunt on the power supply is such that the internal resistance of the power supply or in the presence of multiple internal resistance Stands in the power supply these represent all or part of the usable impedance.
- control device in which this has a comparator for zero-crossing detection and in which is connected to at least one input of the comparator switchable by the logic unit biasing branch for biasing the comparator.
- the invention is also achieved by a method for operating such a control device, in particular for determining the time of commencement of a modulation phase, which adjoins an operating phase, in which the output stage is deactivated in the control unit before the beginning of the lamp unit side switched bypass current and the parallel branch are activated and with the detection of the bypass current, the output stage is activated and the parallel branch is deactivated before the data transmission begins.
- an impedance can be added or provided by the switchable parallel branch to increase the measurement contrast of the level to be evaluated of a particularly commercially available comparator for the purposes of the zero-crossing determination. Then, a zero crossing detection performed by a comparator is not or not solely responsible for the otherwise common impedance provided by the final stage. To detect a zero crossing, the output stage is deactivated and the parallel branch is activated. If the output stage is implemented by MOSFET bridges, which is not uncommon in such control devices, the voltages applied to the comparator, which are also shared with a voltage divider, are typically below the offset voltage of commercially available cheaper comparators.
- the switchable parallel branch which is preferably designed to be current-limited, the level at the comparator can be increased.
- the internal resistance of a device already present in the control device is expediently used.
- the already existing power supply be used.
- the parallel branch is preferably connected by an electronic switch, for example, a transistor, which is controlled by the logic unit, which is preferably designed as a microcontroller.
- the internal resistance of a typical power supply is about 100 ohms while the impedance of a MOSFET is only about 1 ohms.
- a modulation phase can serve a timing, starting from a detected mains voltage zero crossing and by calculating the time the expected next zero crossing to begin data transmission.
- a synchronization of the data transmission can be affected by disturbances in the supply network, such as by ripple control signals, which in turn has a shift of the zero crossings result.
- the switchable parallel branch is also used, preferably combined with a time control.
- This method uses the fact that a shunt is switched on the lamp unit side after the operating phase in which the lamp unit has taken up the energy necessary for its operation has been completed.
- the shunt is detectable in the control unit upstream of the lamp unit.
- the output stage is deactivated and the parallel branch is activated. tivated.
- the power amplifier is activated and the parallel branch is deactivated before the data transmission begins.
- a predefined time is awaited with the beginning of the detection of the sidestream flow (for example, ⁇ ⁇ ⁇ ), before the data transmission begins.
- the data transfer is coupled to the beginning of the lobe flow phase of the lamp unit and not to an expected zero crossing, from which, calculated back in time, the beginning of the modulation phase is calculated.

- FIG. 3a shows a schematic representation of a comparator as part of the control unit of the illumination system of FIG. 1 according to a further embodiment, FIG.
- FIG. 4 A schematic representation of a part of the control device of FIG. 1 and FIG. 5: A representation corresponding to that of FIG. 2c with the status display of further devices of the control device.
- the illumination system illustrated schematically in FIG. 1 comprises a control unit 1 with an operating element 2, which may be designed, for example, as a pushbutton or as a rotary knob.
- the control unit 1 is connected on the input side to the supply line of the load - the phase L - of an AC network, typically the usual house network with 230 volts of effective AC voltage.
- the control unit 1 On the output side, the control unit 1 is connected via a supply line 3 to a control gear 5, which is additionally connected on the input side to the neutral conductor N and which in turn operates a light source 6.
- an energy-saving lamp (ESL) is provided as the light-emitting means 6.
- a converter 4 converts electrical energy from the AC voltage network into a form for operating the luminous means 6.
- the converter 4 as part of the energy-saving lamp 6 comprises the necessary units for operating the same.
- Operating device 5 and 6 bulbs form the energy saving lamp as a lamp unit 7, for example, designed as a compact fluorescent lamp.
- a control information can be entered, for example by turning a knob or pressing a button, which is converted by the control unit 1 in a modulation, with the forwarded via the line 3 supply voltage to the lamp unit 7 is transmitted.
- the modulation is decoded on the lamp side by a decoder assigned to the operating device 5 and used to control the light source 6.
- the control unit 1 and the operating device 5 corresponding signal processing units, such as processors, such as microprocessors.
- the control unit 1 comprises a modulator (not shown in the figures) for modulating control information on specific portions of the half-waves of the alternating voltage network L, N conducted to the lamp unit 7.
- the control information itself is set via the operating element 2, as already briefly explained above , This may be, for example, a brightness information and / or another operating setting of the lamp unit 7, in particular of the lighting unit 6 assigned to the lamp unit 7.
- the operating device 5 of the lamp unit 7 comprises a shunt resistor 9 which can be activated via a switch 10.
- the decoder assigned to the operating device 5 for decoding the transmitted control information is identified by the reference numeral 11.
- the lamp unit 7 On the input side, the lamp unit 7 has a full-bridge rectifier 12, which is connected to the line 3 and the neutral conductor N.
- the decoder 1 1 acts with the decoded control information to the illuminant 6 acting on the converter 4.
- the decoder 1 1 also controls the switch 10 at.
- the lamp unit 7 can comprise further circuits which may be necessary for the operation of the luminous means 6, for example for limiting the current or for generating a higher frequency, which are usually realized in a converter as integrated ballast of a compact fluorescent lamp.
- the control unit 1 is further associated with a circuit only symbolically represented capacitor 8 as energy storage, with which the control unit 1, if necessary, as explained below, is supplied with operating voltage. If the control unit 1 relates its operating voltage via the shunt of the lamp unit 7, the capacitor 8 is charged. The operating energy is output in those operating states of the lighting system in which the control unit 1 does not absorb energy.
- the rectifier 12 By the rectifier 12, the positive and negative components of the phase AC and neutral N voltage applied AC voltage are rectified so that two positive half-waves are transmitted within an AC voltage period.
- the illuminant 6 At low voltage, d. H. in the lower part of the rising part of a half-wave, the illuminant 6 does not pick up any energy, at least no energy essential to its operation.
- the current consumption of the lamp unit 7 is shown by way of example in the diagram of FIG. 2a. From this it can be seen that the lamp unit 7 and thus the light source 6 serving as the light source and the ballast receive their operating energy at an interval between about 50 degrees to about 100 degrees of each half wave.
- the curve of the power consumption is shown in Figure 2a by the reference F, and while at an operation of the bulb 6 at full power.
- the dashed curve F 'in FIG. 2a describes the operating current consumption in the dimmed state.
- a shunt phase PN is shown schematically in FIG. 2a.
- the shunt phase PN is completed before the lamp unit 7 receives operating energy, which is the case when a phase interval of about 60 ° is reached.
- the last part of the half wave is designed as a modulation phase P M.
- control unit 1 can absorb operating energy and charge its energy store (in this case: capacitor 8) when the shunt switch 10 is closed. If, however, the shunt switch 10 is opened, the control unit 1 can lose no power from the applied AC voltage. This is intended to not affect the power consumption of the lamp unit 7. In order nevertheless to supply the control unit 1 with the switch 10 open with the necessary energy, the capacitor 8 is used, which supplies the control unit 1 with energy in these phases.
- the following half-waves which are no longer shown in FIG. 2a, likewise each have a further modulation phase, since the control information to be transmitted is subdivided into a plurality of consecutive half-waves.
- the shunt phase P N is designed such that in a first part of the shunt phase P N a higher shunt current flows than in a subsequent, shorter shunt phase, from which second level the shunt phase is terminated.
- a higher shunt current flows than in a subsequent, shorter shunt phase, from which second level the shunt phase is terminated.
- the first part of the shunt phase is used to charge the control unit 1 associated energy storage 8.
- the termination of the shunt phase, starting from the higher current flow to form an intermediate level here: about 20 mA ).
- FIG. 2b shows the voltage profile at the energy-saving lamp 6 or the Lamp unit 7.
- the control information modulated in the illustrated embodiment with constant modulation voltage.
- the shunt created in the lamp voltage becomes noticeable by a voltage drop.
- FIG. 2c shows the voltage curve during the above-described different phases of a half-wave at the control unit 1. It can clearly be seen that in the shunt phase P N, the controller 1 allows more voltage than during the modulation phase P M in the last part of the half-wave.
- the control unit 1 has a comparator 1 3 for detecting a zero crossing of the voltage applied to the control unit 1 AC voltage. Schematically shown in Figure 3, connected to the line L and the supply line 3, the comparator 1 3 of the control unit 1 is shown.
- the comparator 1 3 is connected to a logic unit 14.
- the comparator 1 3 in those half-wave components in which it is not needed, biased so that at this input side a defined signal is applied and there is no risk that it begins to oscillate.
- bias branch 1 5, 15.1 is connected at each input of the comparator 1 3.
- the bias branches 1 5, 1 5.1 are switchable by the logic unit 14 and are activated in the illustrated embodiment after detecting a zero crossing to bias the comparator 1 3, and deactivated to detect the subsequent zero crossing in time before the expected next zero crossing.
- the two bias branches 1 5, 1 5.1 are typically activated immediately after the start of the bypass phase PN- which adjoins a zero crossing.
- the bias branches 1 5, 1 5.1 are deactivated after completion of the modulation phase P M - biasing of the comparator 1 3 is applied to this on the input side defined signal, especially if, as seen in Figure 2a, in certain parts of the half-wave no or only a minimal current flows, as this between the shunt phase PN and the beginning the operating phase of the lamp unit 7 (curve F or F ') and the end of the operating phase and the beginning of the modulation phase P M bridged.
- a symmetrical biasing of the comparator 1 3 is provided. Therefore, a bias branch 1 5 or 1 5.1 is connected to each input of the comparator 1 3. In a simplified alternative embodiment, only one input of the comparator is connected to a bias branch. This too leads to the desired success.
- FIG. 3 a shows an alternative embodiment of a comparator circuit which functions in the same way as the comparator circuit of FIG. 3, but only has a smaller component complexity and can be implemented in a more space-saving manner.
- the logic unit 14. 1 is assigned the comparator. Consequently, the comparator is part of the logic unit 14.1, which is preferably designed as a microcontroller.
- the logic unit 14.1 which is preferably designed as a microcontroller.
- each bias branch 1 5.2, 5.3 each have a capacitor turned on. These capacitors are designed so that they do not distort the zero point in the time domain or only insignificantly.
- FIG. 4 shows parts of the control unit 1 in the manner of a schematic block diagram.
- the control unit 1 is connected with its input 16 to the load line L and with its output 17 to the supply line 3 connecting the control unit 1 to the lamp unit 7.
- the control unit 1 has a switchable output stage 18, which is realized in the illustrated embodiment by a MOSFET bridge.
- the two MOSFETs 19, 19.1 of the MOSFET bridge are in turn connected to the logic unit 14 of the control unit 1, which controls these power switches.
- Part of the control unit 1 is also a power supply
- control unit 1 further has a switchable parallel branch
- the parallel branch 21 has a control branch 23 with an electronic switch embodied as a transistor Ti in the exemplary embodiment shown, which is connected to the logic unit 14, as shown diagrammatically in FIG. Thus, the transistor Ti is driven by the logic unit 14.
- the control branch 23 has a second transistor T 2 for switching through the parallel branch 21 to the power supply 20 for activating the parallel branch 21.
- the internal resistance of the power supply can be used for certain purposes by the bypass characteristic of the parallel branch 21 closed via the control branch 23
- the usable in this regard provided by the power supply 20 impedance results from the sum of the resistors R 1, R 2 and the impedance of an arranged between the two resistors R 1, R 2 in the illustrated embodiment electronic switch 22, as a MOSFET in the The electronic switch 22 is actuated by the control branch 23 or by the switching transistor T 2 contained therein
- the shunt provided by the parallel branch 21 is current-limited.
- subsequent modulation phase PM in which an applied to the lamp unit 7 AC voltage control information is transmitted control unit side is the beginning of the lamps - Unit-side shunt phase expected.
- the MOSFETs 19, 19.1 of the output stage 18 are deactivated. With the deactivation of the output stage 18 of the drive branch 23 and thus the parallel branch 21 is activated simultaneously. It is now possible to detect the timing of the switching of the lamp-side shunt N L on the control unit side.
- the lamp-side shunt N L is the control unit side detected in the illustrated embodiment in Figure 5 at time t 2 .
- the control unit-side detection of the lamp-side closed shunt N L is the control command for the control unit 1 that the modulation phase P M has begun.
- a certain time interval from the detection of the shunt current N L of the lamp unit 7 will be defined at the time t 2 .
- the actual data transmission in the modulation phase PM begins at time t 3 .
- the output stage 18 is part of the modulation stage of the control unit 1 and is thus switched on and off according to the data to be transmitted.
- the parallel branch 21 is deactivated at time t 3 by switching off the control branch 23.
- the time interval between the control unit detection of the start of the bypass flow N L of the lamp unit 7 at time t 2 and the beginning of the data transmission at time t 3 is dimensioned such that the time defined in terms of their length data transmission is completed before the expected next zero crossing, with a certain temporal distance to the expected Zero crossing (here: at time t 4 ). This ensures high reliability in data transmission.
- the voltage applied to the comparator 13 bias is turned off, the power amplifier 18 is deactivated and the parallel branch 21 activated. This adjustment is made before the expected zero crossing of the half-wave, in the illustrated embodiment at the time t 4 . Since the parallel branch 21 is activated, the comparator 13 then has a higher level K P.
- the current limit in the power supply 20 can be switched. This serves the purpose of keeping the current conducted by the power supply 20 smaller than the secondary current flow provided on the lamp unit side so that the voltage at the end of the bypass phase P N across the control unit 1 does not collapse uncontrollably. This may be required to comply with standards. Such switching over of the current limitation takes place via the power supply 20, which for this purpose has a switchable circuit with different zener diodes for limiting the current.
- Such a configuration of the switchable current limiting in the power supply 20 as described above, can also be used independently of the other measures described in connection with the control unit 1 and is therefore also suitable for use in other control devices.
