Definitions

  • ballast is mainly used when the at least one lamp, in particular in the form of a spotlight or spotlight, is used at a greater distance from the ballast. This is the case, for example, with film and television recordings.
  • the task of the ballast is to supply the lamp with the operating voltage for the lamp and also to ensure a safety shutdown if, for example, a glass breakage occurs in the glass pane of the lamp, which means that the lamp would no longer be safe to touch with regard to the operating voltage. It is also known to continuously measure electrical parameters of the connected lamp in the ballast when the ballast is switched on in order to adapt the output power of the ballast to the power consumption of the light source.
  • the known lighting arrangements are designed in such a way that they withstand rough field operation and require connecting cables with as few conductors as possible.
  • analog circuit technology was used, which enabled implementation with the existing conductors of the cable.
  • EP 2 434 207 A1 it is generally known to provide bidirectional data transmission between a lighting unit and a control device on the one hand and between the control device and an energy supply device formed, for example, by a photovoltaic system on the other hand.
  • the energy supply device produces a direct current
  • the lighting means of the lighting means unit can be operated with the direct current.
  • LEDs are used in particular as light sources.
  • the problem of a lamp arrangement that is operated with AC voltage signals, has a lamp that can be ignited by ignition pulses and must be suitable for rough field operation is not addressed by the previously known lighting system.
  • the present invention is based on the object of expanding the application possibilities of the known lighting arrangements, preferably with a technology that does not necessarily require additional conductors or the use of special cable technologies.
  • the task is solved by the lighting arrangement with the features of claim 1 .
  • the lamp has at least one sensor and a microcomputer and the ballast has a microcomputer and that between the microcomputers, a bidirectional digital data exchange is provided with a data transmission circuit and a data reception circuit in the ballast and in the lamp via conductors of the cable that are not intended for the transmission of the operating voltage for the lamp and that the data transmission circuits as a current source with a high internal resistance and the data reception circuits are designed with a low internal resistance and with low-pass filters.
  • the ballast contains the essential circuit technology in the usual lighting arrangements and the lighting arrangement has only included the light source and an ignition circuit for this purpose
  • the concept of the invention provides that the light of the lighting arrangement receives its own intelligence from a microcomputer. This makes it possible to determine essential parameters of the lamp during operation. These include, for example, the burning voltage of the lamp, in particular the arc of an arc lamp, the temperature of the lamp socket, the temperature of the reflector, the temperature of the ignition device, the orientation of the lamp in the gravitational field to prove improper operating positions of the lamp, a count of operating hours and, if necessary, monitoring safety devices. Since the lamp should continue to be controlled and monitored by the ballast, the bidirectional digital data transmission according to the invention is provided via the cable. In this way, controlled by the ballast, information from the lamp reaches the ballast and is stored there and/or used to initiate suitable control and/or signaling measures.
  • the supply voltage for the microcomputer and the data transmission circuit and data reception circuit of the lamp is via conductors of the cable transmitted, which are not intended for the transmission of the designed as AC voltage operating voltage of the lamp. In principle, it would be obvious to derive the supply voltage from the operating voltage of the lamp of the lamp.
  • the microcomputer, data transmission circuit and data reception circuit of the lamp would then only be active when the operating voltage for the lamp is being transferred from the ballast to the lamp.
  • this would significantly limit the usability of the microcomputer and the sensors that can be connected to it.
  • the operating voltage can be provided as a pulsed AC voltage by reversing the polarity. It is advantageous if direct current is switched with a full bridge circuit in an inverter stage in such a way that the voltage potential is applied alternately to one line or the other on two output lines, so that a current with alternating polarity can flow on the two output lines.
  • the data transmission circuit of the lamp can be activated by a transmission of data from the ballast.
  • the microcomputer can temporarily store data from the sensors connected to it and transmit it to the ballast after a corresponding request by the ballast.
  • Data is transmitted from the ballast to the lamp and from the lamp to the ballast via conductors in the cable that are not intended for transmitting the operating voltage for the lamp.
  • the data transmission circuit and data reception circuit of both the ballast and the lamp are connected to conductors of the cable that are not intended for the transmission of the operating voltage.
  • the data transmission circuit and data reception circuit of both the ballast and the lamp can be connected to the same two conductors of the cable, so that the bidirectional data transmission takes place in both directions on the same two conductors.
  • These conductors can be those conductors which are connected to the terminals of the ballast for the sensor circuit and to the two terminals of the luminaire which are connected to the at least one switch.
  • These conductors can be connected to a differential circuit both in the ballast and in the luminaire, so that the useful data signal is obtained by forming the difference. A superimposed interference signal affecting both conductors would then be eliminated in the known manner when the difference is formed.
  • the data transmission circuits are designed as current sources with a high internal resistance and the data receiving circuit with a low internal resistance in order to reduce the effects of inductively coupled interference.
  • the interference is kept away from the respective data receiving circuit even if the interference coupled in inductively or by transformer is in the data transmission band in terms of frequency.
  • the data receiving circuits can have low-pass filter circuits with such a limit frequency that higher-frequency, capacitively coupled crosstalk interference is separated from the useful data signal.
  • figure 1 shows the basic structure of a ballast 1, a lamp 2 and a cable 3 connecting the ballast 1 to the lamp 2.
  • the ballast is connected to a standard AC voltage supply with the conductors L1, N and PE (protective conductor connected to the housing).
  • the AC voltage transmitted on the conductors L1, N is rectified and smoothed in a rectifier circuit 4.
  • a direct current is generated and controlled in a known manner.
  • the direct current is switched in a known manner with a full bridge circuit 7 in such a way that the voltage potential is applied alternately to one line or the other on two output lines, so that a current with alternating polarity can flow on the two output lines.
  • the output lines are connected to lines LH and LL of the cable 3 via a safety switch 8 via an EMC filter 9 .
  • the lines LH and LL lead to two electrodes of a lamp 10, through which current thus alternately flows in one direction and in the other direction.
  • the illuminant 10 can be embodied in different embodiments, according to current technology it is preferably a high-pressure discharge lamp, for example a high-pressure metal halide lamp. Inductances are used in the lines leading to the illuminant 10, via which current surges generated by an ignition pulse generator 11 reach the electrodes of the illuminant 10 as ignition pulses in order to ignite the illuminant 10.
  • a conductor Z of the cable 3 in the ballast is connected to an ignition switch 12 with the conductor LH or the corresponding output of the inverter stage 6 .
  • the conductor Z is connected to the conductor LL via a primary coil of a transformer 13, so that a capacitor 13a connected to the secondary winding of the transformer 13 is charged to the breakdown voltage of a spark gap 14, which is also arranged on the secondary side of the transformer 13 .
  • a spark gap 14 With the ignition of the spark gap 14, an oscillating circuit is formed from the capacitor 13a and the connected inductance, in which a heavily damped oscillation of typically 1 to 5 MHz is caused by the charge introduced in the capacitor 13a.
  • This oscillation is connected in series with the electrodes of the illuminant 10 Inductances are coupled in, as a result of which a very high voltage is superimposed in a pulsed manner on the supply voltage of the lamp, which leads to the lighting means 10 igniting.
  • ignition device 11 there is already an internal connection between ignition device 11 and terminal LH, which is controlled by an integrated timer. If this version is used, the line marked Z can be omitted or is no longer connected to the lamp 2.
  • the cable also contains two lines D+, D-, which serve to loop through a potential and form a sensor circuit for at least one switch 15, 16 contained in the lamp 2.
  • These switches 15, 16, which are designed using analog technology, can be closed in the operating state, so that the closed state of the switches 15, 16 in the ballast 1 can be seen. If one of the switches is opened, for example if the glass pane of the light 2 breaks or by a door contact switch that gives access to the light 2, a safety shutdown can take place in the ballast by the safety switch 8 being opened, for example by a relay, so that the lamp 10 of the lamp 2 is no longer supplied with an operating voltage.
  • a data module 17 with a microprocessor 18 and a data module 19 with a microprocessor 20 are arranged on the conductors D+ and D- of the cable 3 in the ballast 1 .
  • a bidirectional data exchange takes place between the data modules 17, 19, which takes place on the conductors D+, D- already present for the sensor circuit, so that the cable 3 does not require any additional conductors for the data exchange.
  • the voltage for the data module 19 in the light 2 is also supplied via the conductors D+, D-.
  • Figure 2a schematically illustrates the conductors combined in cable 3, with the in figure 1 The number of conductors shown can easily be increased, as shown in figure 2 is shown in dashed lines.
  • Figure 2b shows that the conductors LH and LL provided for supplying the lamp 10 with the operating voltage and the protective conductor PE are designed with a significantly larger cross-section than the conductors D+, D- and Z, which are designed for a lower current, and possibly .additional ladder.
  • the conductors are in the cable 3 within a stable cable sheath 21.
  • the arrangement of the conductors in the cable 3 has the consequence that the conductors D+ and D- provided as data conductors have different distances to the conductors LH on the one hand and LL on the other hand provided for the high powers. Due to its design, the conductor system forms a system of coupled inductances 22 that Figure 3a is illustrated.
  • FIG. 3b The diagram shown shows the curve 23 of the lamp current I L on the conductors LH and LL.
  • the diagram arranged below according to Figure 3c shows the resulting course 24 of the interference pulses resulting from inductive coupling.
  • the lamp current in the example of a 9 kW lamp 10 in a typical application changes between -55 A and +55 A in a period of about 20 to 30 ⁇ s ( Figure 3b ) creates an induced voltage pulse with a width of typically 20 to 30 ⁇ s.
  • the typical maximum pulse voltage U max is around 7 V for a cable length of 15 m and reaches values of up to 50 V for a cable length of 100 m.
  • figure 4 shows schematically a capacitive coupling 25 that is also present between the conductors of the cable 3, which is why in Figure 4a symbolically discrete capacitances are drawn in between the conductors, which of course do not exist as such. Rather, the conductors form capacitances distributed over the length.
  • FIG 4b shows schematically a capacitive coupling 25 that is also present between the conductors of the cable 3, which is why in Figure 4a symbolically discrete capacitances are drawn in between the conductors, which of course do not exist as such. Rather, the conductors form capacitances distributed over the length.
  • FIG 4b shows schematically a capacitive coupling 25 that is also present between the conductors of the cable 3, which is why in Figure 4a symbolically discrete capacitances are drawn in between the conductors, which of course do not exist as such. Rather, the conductors form capacitances distributed over the length.
  • figure 6 shows an example of a schematic structure of the data transmission circuit 26 of the ballast 1 and a data receiving circuit 30 of the lamp 2 connected via the conductors D+, D- of the cable 3.
  • the data transmission circuit 26 and the data receiving circuit 30 are basically the same in the ballast 1 and in the lamp 2.
  • figure 6 therefore shows the essential parts of the circuit for data transmission from the ballast 1 to the lamp 2, while figure 7 the corresponding circuit parts for the return of data from the lamp 2 to the ballast 1 illustrate.
  • the microprocessor 18 For the transmission of data from ballast 1 to luminaire 2 ( figure 6 ) the microprocessor 18 generates ( figure 1 ) Corresponding data contents TX B that reach a control circuit 31.
  • the control circuit 31 is activated with a start signal (enable signal En B ).
  • the control signals A, B, C, D required for switching a current source 33 designed as a full bridge 32 are provided at the output of the control circuit 31 .
  • transistor "A” allows a defined current flow into the D+ conductor
  • transistors “B” and “C” block
  • transistor “D” causes a defined current flow into the D- conductor, so that on the bridge diagonal D+ goes up and D - be pulled down.
  • current flow is now generated up through transistor “B” in D- and down out of D+ through transistor “C”, and in state 3 the full bridge is passive, then data can be received.
  • the bipolar transistors shown can be designed, for example, as MOSFETs or as JFETs, or other components or component groups with comparable properties.
  • control means that the base of the respective transistor is connected to a voltage that is slightly different from the respective supply voltage, so that minus the emitter-base voltage, a voltage drops across the resistor such that a defined current flow at the collector can be removed.
  • a filter 36' is placed between this current driver circuit and the conductors D+, D- in the cable.
  • the conductors D+ and D- are connected via the series-connected switches 15, 16 to a first filter 36 which is designed in such a way that it is suitable for transmitting the supply power of the data module 19.
  • a first filter 36 which is designed in such a way that it is suitable for transmitting the supply power of the data module 19.
  • This is followed by a second filter 37 before the signals on the two lines D+, D- are fed to a subtraction stage 38 (D+-D-).
  • This subtraction stage 38 eliminates those interferences which are injected into the two conductors D+, D- in the same way and in phase.
  • the received signal RX L formed in this way then reaches the microprocessor 20 of the lamp.
  • a voltage supply stage 39 is connected to the output of the first filter 36 in parallel with the second filter, which voltage supply stage 39 obtains a supply voltage VDD L from the transmitted data signals using a full bridge circuit and a downstream storage capacitor.
  • an operational amplifier 41 as a detector for the Switch state of the switches 15, 16 connected. If one of the switches 15, 16 in the lamp 2 is open, no current flows when the diagonal connections A, D or B, C are activated, so that no voltage drops across the base point resistor 40. This is detected by the operational amplifier 41, which in this case lowers its level at the output so that the relay in the safety circuit 8 ( figure 1 ) opens the switching contacts and interrupts the operating voltage for the illuminant 10.
  • the operational amplifier module 41 is equipped with a low-pass filter so that during the brief interruption in the current flow (enable signal En B deactivated), as occurs during data transmission from the radiator back to the ballast, the "D ok" signal at the output of the operational amplifier 41 is still uninterrupted remains set.
  • FIG 7 shows the data receiving circuit 30 in the ballast 1 and the data transmission circuit 26 in the lamp 2.
  • the microprocessor 20 of the lamp 2 receives a data signal from the ballast 1, with which the transmission of certain data is requested, it generates the corresponding data signals as transmission signals TX L and generates a switch-on signal En L for the controller 31.
  • the data signal reaches the conductors D+, D- via the current source 33 and the filter arrangement 36.
  • the processing in the data reception circuit 30 takes place with the filters 36' and 37' as well as with the subtraction circuit 38', as explained with reference to the data reception circuit 30 for the lamp 2.
  • the microprocessor 18 of the ballast sets the enable signal En B to zero, so that the data transmission circuit 26 of the ballast 1 is switched off and the received signals are not affected.
  • the data transmission circuits 26 and data receiving circuits 30 in the ballast 1 and in the lamp 2 are constructed in the same way in principle, there are minor functional differences. While the voltage swing in the passband of the first filter is limited to VDD L in luminaire 2, overshooting in the ballast must be allowed. A regulator (not shown) is used in the lamp 2 to prevent the voltage VDD L from rising above a limit. For this purpose, the storage capacitor, which provides the energy for sending the data back from the lamp 2 to the ballast 1, is discharged somewhat when the target voltage is exceeded, until the target voltage is reached again. The discharge can take place via a connected ohmic resistor.
  • FIG 8 a schematic complete circuit for the data module 17 of the ballast 1 and the data module 19 of the lamp 2 is shown. It becomes clear that the filter 36 is used both for the transmission and for the reception of the digital signals.
  • inductively coupled interference has no effect on the data transmission if the data is transmitted using a current source 33 with a high internal resistance at the transmitter end.
  • Capacitively coupled interference as in figure 8 are indicated, have an effect on the transmission circuit in that the coupling capacitances 25 of the cable 3 with the receiver resistance 28, 29 ( figure 5 ) form a high pass.
  • the capacitively coupled interference is at a frequency ⁇ 300 kHz. Accordingly, the filters 36, 37 and 36', 37' serve as low-pass filters, with which, in particular with the filters 37, 37', the high-frequency interference is strongly damped.
  • the subdivision of the filter into the first filter 36 and the second filter 37 is based on the fact that the first filter 36, 36 'can also be used for transmission and is suitable for the transmission of larger powers, while the second filter 37, 37' for the damping of the capacitively coupled interference are designed for interference-free data reception. Examples of the filters are in the figure 9 shown.
  • the filter 36' shown is designed for the transmission of power for transmission and reception in the ballast 1. Consequently, the coil L1 forms a low-pass filter with the capacitors C1, C2 and the resistor R1, which keeps large voltage swings away from capacitive coupling.
  • the switch SW1 is open, so that R1 and C2 act as attenuators to lower the quality factor of the L1-C1 combination in order to prevent excessive voltage increases in the range of the resonant frequency.
  • D+ and D- have a high resistance to one another, as required for the current source concept.
  • SW1 In receive mode, SW1 is closed and R1 and R1' operate as terminating resistors.
  • the resonance of the L1-C1 filter is damped, but it remains low-impedance below the L1-C1 cutoff frequency.
  • Figure 9b shows an embodiment of the first filter 36 in the lamp 2.
  • This filter is also designed for power transmission and keeps voltage drops small because a low-pass filter is formed with the coil L2.
  • L2 low-pass filter
  • large voltage swings from capacitively coupled interference are kept away from the current source by the low-pass filter L2, C3.
  • the receiving voltage VDD L is reached by charging the storage capacitor using a bridge rectifier, the lines D+, D- are evaluated with low resistance by the receiver.
  • the data is sent back in a time interval determined by the stored energy of the storage capacitor, the voltage VDD L is reduced. This means that there is no switchable termination and the downstream combination of R2-C4 is used exclusively to suppress the resonance of the upstream L2-C3 combination.
  • Figure 9c shows an embodiment of the filter 37, which is no longer suitable for power transmission, but is used to set a low-pass cut-off frequency.
  • the filter can be implemented with inexpensive RC low-pass filter chains. Since this filter follows the first filter 36, the connection between R2, C4 ( Figure 9b ) of the first filter 36 is effectively the first low-pass filter of the low-pass chain of the filter 37.
  • the filter 37' shown also consists of inexpensive RC low-pass filter chains.
  • the connection point for filter 37' to filter 36' is between L1, C1 and R1 ( Figure 9a ), since the connection point between R1 and C2 is connected to R1', C2' during reception.
  • the signal filter 37' is designed one order higher than the signal filter 37.
  • the filters are designed in such a way that capacitively coupled interference is effectively dampened.
  • the consequence of this is that the data transmission rate has to be adapted to the passband of the low-pass filters 36, 37 and 36', 37'. Since the amount of data to be transmitted is limited, this does not mean that there are any significant limitations in the application for data exchange between ballast 1 and luminaire 2.
  • the exemplary embodiment shown is based on the fact that when data signals are transmitted via the conductors D+, D- from the ballast 1 to the luminaire 2, a storage capacitor is charged from these transmitted signals in the luminaire 2 after rectification, the stored energy of which is used for the return of the the data signal of the ballast 1 requested data volume is sufficient.
  • the data can therefore only be sent back in a short time interval after the request by means of a data signal from the ballast 1 . In this way, the lamp does not need its own power supply for the purpose of data transmission.
