• a control lever is to act as a control element, which can be tilted and / or rotated and / or pressed in different positions, so as to actuate switch contacts of a switching device, which control a controller, in addition to the aid of a per color channel separate power module in addition to the desired brightness to set the desired light color of a light source,

• the control lever is tiltable out of a middle position serving as a rest position into six different positions "upper left", "upper middle", "upper right", "lower left", "lower middle", "lower right", whereby the Intensity of three different color channels can be specified to the controller and is adjustable by the power modules and
• the controller has a time detecting member which detects the time duration of the application of a switching contact as a result of pressing the control lever, whereby by briefly pressing the control lever is switched on or off the dimmer and storing a predetermined minimum brightness occurs when the control lever for a predetermined period of time in its middle position is kept pressed.

Advantageously, therefore, the brightness and the light color of a modern light source, z. B. on LED basis, depending on the specific use in the desired manner and be set independently. However, it is kept open whether the operating element and the lighting means are arranged within a unit or connected to one another via installation lines. Separating the keypad and lamp requires several (at least four) installation leads, which requires relatively high installation requirements. Furthermore, the pulse width modulation PWM usually used for LED brightness control generates a non-negligible radio interference spectrum when using several meters long installation cables.

The invention has for its object to provide an optimized method for setting the control of multiple lights.

• wobei das empfangene Helligkeits-Informationssignal im Speicher des Steuerbausteins der angewählten Leuchte abgespeichert und für die Ansteuerung des Leuchtmittels verwendet wird.

This object is achieved by a method for adjusting the control of at least two connected to a common control device lights whose at least one light source is powered by its own power supply, which feeds a power module with at least one controllable semiconductor device, its control via a control module including evaluation unit and memory,

• wherein the control device from the phase of an AC voltage network generates a processed phase with signal sequences and the lights,
• wherein the processed phase is first provided with a synchronization signal, followed by at least one full wave,
• wherein the number of full waves transmitted after the synchronization signal together with the synchronization signal represents an individual addressing signal sequence to a specific, selected luminaire,
• the control device of the selected luminaire transmits a desired brightness information signal in an information signal sequence following the addressing signal sequence,
• wherein the received brightness information signal is stored in the memory of the control module of the selected luminaire and used for the control of the luminous means.

The achievable with the present invention consist in particular in that the full waves of the mains voltage can be used as quasi communication time slots both for addressing and for the information signals regarding the brightness and light color of each individual lamp of the system. The installation costs caused by additional devices or installation cables to be additionally laid is very small and, in comparison to the known state of the art, very reduced; in particular, the control unit does not necessarily have to be connected to the neutral conductor. The method is suitable both for lights with white light as well as for lights with any light color, formed from red / green / blue light colors each with the desired brightness.

The information transmission from the control unit to the lights is DC-free, ie it is at all times the conditions of an AC voltage met, in particular, the installation cables are not subjected to pulsating direct currents. For example, the DC components supplied to the phase due to a drive method would be very disturbing for the proper operation of RCCBs used in the installation system. The power supplies of the lights are continuously supplied with full line voltage, only interrupted by the very short time periods during which addressing signal frequencies and information signal frequencies are generated to change the brightness and / or light color of the lights. Accordingly, a good efficiency results. The EMC load (electromagnetic compatibility) is very low. The operation by means of actuation of the drive device is simple and clear. The power supply unit, the control module and the power module of the Lights on the one hand and the spatially separate control unit on the other hand can be designed in the form of flush-mounted device sockets (flush-mounted inserts).

Advantageous embodiments of the invention are characterized in the subclaims.

Thus, the end of an addressing signal sequence may be indicated by an incomplete full wave, e.g. B. by a 50% driven solid shaft.

The brightness information signal to be transmitted can be generated in the form of the temporal voltage curve of an information power wave by appropriately influencing a full wave.

The drive device can influence the phase angle of the mains voltage during this wave in order to generate an information power wave. The control module of the selected luminaire can determine the current flow time occurring during an information grid wave as a measure of the phase angle of this wave.

The control unit can block a complete full wave of the mains voltage to generate the synchronization signal.

The full waves of the mains voltage following the addressing signal sequence can serve as information network waves for the transmission of separate brightness information signals for the red respectively green respectively blue light color in the form of an information signal sequence.

Between two information power waves, at least one additional full wave for the recharging of the charge capacitor of the power supply can be inserted.

To increase the redundancy, the addressing signal sequences can be repeatedly transmitted together with the information network waves or information signal sequences.

In Fig. 1 is a schematic diagram with multiple, connected via at least one installation cable to a common control device, each having a plurality of light sources (preferably LEDs) of different colors exhibiting lights. The control unit 17 (operating unit, operating element) is connected on the input side to phase L and optionally also to the neutral conductor N of an AC voltage network 15 (230 V AC voltage). The output voltage which can be tapped on the drive unit 17 on the output side is referred to below as the conditioned phase L 'and corresponds to the input voltage of three lamps 1, 13, 14. The lamps 1, 13, 14 are furthermore connected to the neutral conductor N.

The in the form of a designed as RGB LED light (R = red / G = green / B = blue) lamp 1 is composed of two main components or functional units, namely a flush-mounted insert 2 and a plurality of light sources (preferably LEDs) 9, 10th , 11 containing LED module 8 composed, these two main components are detachably connected to each other via mutually corresponding plug contacts.

The flush-mounted insert 2 has on the input side an acted upon with the processed phase L 'and the neutral conductor N power supply 3 (AC / DC converter) including charging capacitor whose positive output (DC or DC) to the emitter terminals of a transistor 5 for Supply of a red light, in particular a red LED 9, a transistor 6 for supplying a green light, in particular a green LED 10 and a transistor 7 for supplying a blue light, in particular a blue LED 11 is connected. The collector terminals of these three transistors 5 and 6 and 7 are connected to the anode terminals of the LEDs 9 and 10 and 11, respectively. The cathode terminals of the three LEDs 9, 10, 11 are connected to the negative output (DC or DC voltage) of the power supply 3.

The luminaire 1 and here in particular the flush-mounted insert 2 has a control module 4 including evaluation and memory, which is connected to both outputs of the power supply 3 and the input side additionally treated with the phase L 'is applied. Optionally, an evaluation circuit 29 may be connected on the input side to L 'and N and on the output side to the control module 4. On the output side, the control module 4 is connected to the base terminals of the transistors 5, 6, 7. Furthermore, the flush-mounted insert 2 has a coding switch 12 (DIP switch) connected to the control component 4, so as to provide each luminaire with a fixed luminaire number or luminaire address - referred to below as I, II and III - within the system with several to assign to a common drive device 17 connected lights 1, 13, 14 can. By means of the coding switch 12, these different DIP switch positions are adjustable.

Of course, other controllable semiconductor components or semiconductor switches can be used instead of the transistors shown by way of example.

The further lights 13, 14 are formed in the same manner in the form of RGB LED lights as the above-described lamp 1.

Of course, other lights can be provided, and it is also possible to assign the same luminaire number or luminaire address I or II or III (or more) to different luminaires. A parallel connection of lights is to reach the maximum load capacity of the drive unit 17, total power z. B. 400 W, possible.

It is essential that each lamp 1, 13 has its own power supply 3, whose power to supply at least three light sources (LEDs) 9, 10, 11, power per LED z. B. 1 W, is sufficient. These three light sources (LEDs) 9 or 10 or 11 are operated via the transistors 5 and 6 or 7 with a pulse width modulation with a constant current. About the pulse width modulation, the lamps (LEDs) 9, 10, 11 variable power can be supplied. This makes it possible to change the brightness with a constant light color.

In this case, the setting of the desired brightnesses and / or the desired light colors of the lamps 1, 13, 14 by the control unit 17 by means of influencing temporal phase control, so that the control unit 17 can also be referred to as a "special dimmer". The control unit 17 now influences the mains voltage U on its output line - denoted by L '- in a change of brightness and / or light color desired by the operator, such that the connected lamps 1, 13, 14 receive the information for their desired brightness from the temporal, forced by the control unit 17 voltage waveform (information signal sequence) in the form of the processed phase L 'is transmitted.

Before the generation and evaluation of the voltage curve is discussed in greater detail, the basic idea of the proposed transmission of information will be discussed to be discribed. A well-known dimmer usually provides at its output a phase or phase voltage for the connected loads. Depending on the phase angle, a more or less high brightness is set on the connected luminaire. The proposed "special dimmer", ie the drive unit 17, in contrast to this, allows the feeding sinusoidal voltage to pass through completely uninfluenced for the greater part of the time. Only to change the brightness and / or light color of the lights, ie with appropriate operation of the control unit 17 by the operator, the drive unit 17 influences the voltage on its output side during a short defined period of time, whereby the processed phase L '(with an addressing signal Sequence and an information signal sequence) is generated. The connected lamps 1, 13, 14 can detect this phase influence by means of their control modules 4 and convert them via the correspondingly controlled power modules into the corresponding desired brightness and / or light color.

For synchronization ("Attention, from now on not only energy but also information will be transmitted"), the control unit 17 blocks a complete full wave of the mains voltage U - see the synchronization _signal T _sync in the following figures. The charging capacitors of the power supplies 3 in the connected lights 1, 13, 14 are dimensioned such that they can bridge this voltage fluctuation in time, without the user would notice a disturbance. However, the control module 4 detects this synchronization _signal T _sync and starts an evaluation routine, which evaluates the following full waves of the mains voltage U.

• ein Zeitschlitz T_A1 für die Adressierung der ersten Leuchte 1 entspricht der Signal-Sequenz "eine Vollwelle" nach Auftreten Synchronisationssignal T_sync und ist der ersten Leuchte 1 zugeordnet,
• ein Zeitschlitz T_A2 für die Adressierung der zweiten Leuchte 13 entspricht der Signal-Sequenz "zwei Vollwellen" nach Auftreten Synchronisationssignal T_sync und ist der zweiten Leuchte 13 zugeordnet
• ein Zeitschlitz T_A3 für die Adressierung der dritten Leuchte 14 entspricht der Signal-Sequenz "drei Vollwellen" nach Auftreten Synchronisationssignal T_sync und ist der dritten Leuchte 14 zugeordnet usw.

The control unit 17 generates now by influencing the mains voltage U respectively the processed phase L 'for setting / acting on a single, specific luminaire a sequence of signals in which the number of full waves after the synchronization signal T _sync the corresponding set luminaire number respectively the lights Address corresponds. This addressing signal sequence (synchronization signal T _sync + one or two or three, etc. full waves) is transmitted via the processed phase L '. An addressing of the lights can z. B. as follows:

• a time slot T _A1 for the addressing of the first luminaire 1 corresponds to the signal sequence "one full wave" after the occurrence of the synchronization signal T _sync and is assigned to the first luminaire 1,
• a time slot T _A2 for the addressing of the second light 13 corresponds to the signal sequence "two full waves" after the occurrence of the synchronization signal T _sync and is associated with the second light 13
• a time slot T _A3 for the addressing of the third light 14 corresponds to the signal sequence "three full waves" after occurrence of the synchronization signal T _sync and is associated with the third light 14, etc.

• mit Zeitschlitz T_A1 entsprechend Leuchten-Adresse respektive Leuchten-Nummer I,
• mit Zeitschlitz T_A2 entsprechend Leuchten-Adresse II respektive Leuchten-Nummer II,
• mit Zeitschlitz T_A3 entsprechend Leuchten-Adresse III respektive Leuchten-Nummer III
• usw.

erfolgt durch entsprechendes Einstellen des Codierschalters 12 einer jeden Leuchte.In the considered embodiment, the coding switch 12 of the first lamp 1 is accordingly to the addressing signal sequence "one full wave" after the occurrence of the synchronization signal, the coding switch 12 of the second light 13 accordingly to the addressing signal sequence "two full waves" after the Occurrence of the synchronization signal and the coding switch 12 of the third light 14 accordingly set to the addressing signal sequence "three full waves" after the occurrence of the synchronization signal. When control unit 17, these different time slots T _A1 , T _A2 , T _A3 , etc. are permanently stored for the addressing of different lights. The assignment of the individual luminaires to the different addressing signal sequences

• with timeslot T _A1 according to luminaire address or luminaire number I,
• with time slot T _A2 according to luminaire address II or luminaire number II,
• with time slot T _A3 according to luminaire address III or luminaire number III
• etc.

is done by appropriately setting the coding switch 12 of each lamp.

Immediately after the generation of the addressing signal sequences, the control unit 17 influences the mains voltage U or processed phase L 'as a function of a brightness and / or light color set by the operator in the form of information signal sequences in such a way that the connected lamps provide the information for their required brightness and / or required light color from the temporal, enforced by the control unit to detect and adjust voltage waveform.

In order to be able to determine the end of the addressing signal sequences, the following phase angle must be less than 100% in order not to select the next light with a renewed full wave. For example, the addressing signal sequence always follows the phase angle for the red light source at 50%. this shows the operator which luminaire he has selected.

• der Phasenwinkel der ersten, einen Kommunikations-Zeitschlitz T_R darstellenden Informations-Netzwelle die gewünschte Helligkeit der roten Lichtfarbe respektive des roten Leuchtmittels (LED) 9 angibt,
• der Phasenwinkel der dritten, einen Kommunikations-Zeitschlitz T_G darstellenden Informations-Netzwelle die gewünschte Helligkeit der grünen Lichtfarbe respektive des grünen Leuchtmittels (LED) 10 angibt,
• der Phasenwinkel der fünften, einen Kommunikations-Zeitschlitz T_B darstellenden Informations-Netzwelle die gewünschte Helligkeit der blauen Lichtfarbe respektive des blauen Leuchtmittels (LED) 11 angibt.

The control unit 17 now provides the information for the brightness of the three light colors in the five full waves following the addressing signal sequence over a brief influence on the phase angle, namely z. B. such that

• the phase angle of the first information power wave representing a communication time slot T _R indicates the desired brightness of the red light color or of the red light source (LED) 9,
• the phase angle of the third information power wave representing a communication time slot T _G indicates the desired brightness of the green light color or of the green light source (LED) 10,
• the phase angle of the fifth, representing a communication time slot T _B information network wave indicating the desired brightness of the blue light color or the blue light emitting device (LED) 11.

• der Phasenwinkel der ersten, einen Kommunikations-Zeitschlitz T_R darstellenden Informations-Netzwelle gibt die gewünschte Helligkeit der roten Lichtfarbe respektive des roten Leuchtmittels (LED) 9 an,
• der Phasenwinkel der zweiten, einen Kommunikations-Zeitschlitz T_G darstellenden Informations-Netzwelle gibt die gewünschte Helligkeit der grünen Lichtfarbe respektive des grünen Leuchtmittels (LED) 10 an,
• der Phasenwinkel der dritten, einen Kommunikations-Zeitschlitz T_B darstellenden Informations-Netzwelle gibt die gewünschte Helligkeit der blauen Lichtfarbe respektive des blauen Leuchtmittels (LED) 11 an.

In order to prevent an excessive drop in the voltage of the charging capacitors of the power supply units 3 during the individual communication time slots T _R , T _G , T _B , it is possible, but not necessary, for the activation device 17 to switch between the communication time slots T _R , T _G , T _{B in} each case an additional full wave W are inserted, ie between the two communication time slots T _R and T _G and between the two communication time slots T _G and T _B , which will take into account by the evaluation of the control module 4 respectively. This measure is recommended for higher LED powers or when using relatively small charging capacitors of the power supplies, but not mandatory. These inserted full waves W are only advantageous for recharging the charging capacitors of the power supplies. Without such additional full waves results for the information signal sequences:

• the phase angle of the first information power wave representing a communication time slot T _R indicates the desired brightness of the red light color or of the red light source (LED) 9,
• the phase angle of the second information power wave representing a communication time slot T _G indicates the desired brightness of the green light color or of the green light source (LED) 10,
• the phase angle of the third, representing a communication time slot T _B information network wave indicates the desired brightness of the blue light color or the blue light emitting device (LED) 11 at.

• dass 1 ms Stromflusszeit dem Zustand AUS respektive 0% Ansteuerung des relevanten Transistors entspricht,
• dass 10 ms Stromflusszeit dem Zustand EIN respektive 100% Ansteuerung des relevanten Transistors entspricht,
• dass bei Stromflusszeiten zwischen 1 ms und 10 ms der entsprechende lineare Zwischenwert für die Ansteuerung gewählt wird, d. h. 5 ms würden danach als 50% Ansteuerung zu interpretieren sein.

The evaluation of the detected by the control module 4 phase angle can, for. B. done by evaluating the occurring during the information-wave power flow time, including z. B. is defined,

• that 1 ms current flow time corresponds to the state OFF or 0% activation of the relevant transistor,
• that 10 ms current flow time corresponds to the state ON or 100% activation of the relevant transistor,
• that at current flow times between 1 ms and 10 ms, the corresponding linear intermediate value for the control is selected, ie 5 ms would then be interpreted as 50% control.

Of course, other definitions can be implemented alternatively in this context. It is important that the desired brightness detected via the phase angle or the current flow time is respectively stored for the individual lamps (LEDs) in the respective control module and used for the control of the individual lamps (LEDs) until a renewed adjustment is made by the control unit 17 and so that information network waves are generated again. To increase the redundancy and a repetition of the information transmission is possible by the information network waves are repeated simply or repeatedly. Thereafter, the voltage is again completely unaffected until the next desired change in brightness and / or light color of the lights set by the control unit 17.

To turn off the lights, the drive unit 17 locks its output voltage L 'complete, which has the advantage that no stand-by losses incurred in the lights when lights are off.

When the luminaires are switched on by corresponding actuation of the drive unit 17, the values set for the brightness and the light color of the luminaires at the last switch-off are expediently adopted by the control modules and adjusted by means of the power modules.

In Fig. 2 are for further explanation in the upper portion of the unprocessed and in the lower portion of the prepared by the driver 17 phase characteristic in a driving example for the first lamp 1 with "red LED OFF / green LED 50% control / blue LED OFF" shown. The addressing signal sequence is T _sync + TA ₁ . The information signal sequence is T _R + T _W + T _G + T _W + T _B (this applies to all FIGS. 2 to 5 ).

• Unterputz-Einsatz 20 mit einem Netzteil 21 (AC/DC-Konverter) inklusive Ladekondensator, Steuerbaustein 22 inklusive Auswerteinheit und Speicher, Codierschalter 23 und Transistor 24 (Halbleiterschalter) sowie
• LED-Modul 24 mit drei weißen, in Serie geschalteten LEDs 26, 27, 28 (selbstverständlich kann alternativ lediglich eine einzige LED oder eine größere Anzahl LEDs vorgesehen sein),

wobei diese beiden Hauptkomponenten über zueinander korrespondierende Steckkontakte lösbar miteinander verbunden sind. Die Installation, d. h. die elektrische Verbindung zwischen Ansteuergerät 17 und Leuchte 19 über aufbereitete Phase L' und Nulleiter N ist unverändert zu der vorstehend erläuterten Konfiguration. Optional kann wiederum die Auswerteschaltung 29 eingangsseitig an L' und N und ausgangsseitig an den Steuerbaustein 22 angeschlossen sein.It is always assumed above that the lamps 1, 13, 14 have several LEDs of different colors. However, the invention is not limited to this specific application, but can also be used in monochrome lights, which have a light source or more bulbs (one or more LEDs) of a color, especially the color white. In Fig. 6 For this application, a schematic circuit diagram of only one single color LEDs (in particular white) exhibiting lamp 19 is shown, consisting of the two main components

• Flush-mounted insert 20 with a power supply unit 21 (AC / DC converter) including charging capacitor, control module 22 including evaluation unit and memory, coding switch 23 and transistor 24 (semiconductor switch) and
• LED module 24 with three white, serially connected LEDs 26, 27, 28 (of course, alternatively, only a single LED or a larger number of LEDs can be provided),

wherein these two main components are releasably connected to each other via mutually corresponding plug contacts. The installation, ie the electrical connection between control unit 17 and lamp 19 via processed phase L 'and neutral conductor N is unchanged from the configuration explained above. Optionally, in turn, the evaluation circuit 29 may be connected on the input side to L 'and N and on the output side to the control module 22.

The control module 23 connected to the base of the transistor 24 in turn receives the processed phase L '. It can be under the Figures 1 - 5 used Control unit 17 are also used for this embodiment, which has the advantage that with a control unit 17 both monochrome lights and (multicolored) RGB LED lights trained lights can be controlled.

If more than one light source (LED) of the same color is provided in each case, these light bulbs are preferably connected in series, so that the power supply unit 21 requires only one transistor output, as well as in FIG Fig. 6 shown. After detection / identification of the luminaire address, the control module 22 then only takes into account the information network wave following the luminaire address, ie the communication time slot T _R , while the information of the following information grid waves is ignored. The phase angle of the first information network wave after the luminaire address accordingly indicates the desired brightness information signal of the luminous means (LED) 26, 27, 28. Accordingly, the drive of the transistor 24 via the pulse width modulation, as also explained above.

Fig. 5 shows the phase curve for a control example for the first light with "red LED 50% control / green LED OFF / blue LED OFF". While the information transmitted in the time slot T _{R is used} to drive the transistor 24, the information transmitted in the time slots T _G and T _{B is} ignored.

In Fig. 7 a schematic diagram of a lamp is shown with the use of potential-free phase detection, wherein the embodiment according to Fig. 6 Reference is made. By way of example for an evaluation circuit 29 for detecting the magnitude of the phase angle, an optocoupler 30 with a series resistor 31 connected in series is connected on the primary side between the processed phase L 'and the neutral conductor N. On the secondary side, the optocoupler 30 is connected between the negative output of the power supply 21 and the input of the control module 22 intended for phase detection. Of course, this development is also according to the embodiment Fig. 1 can be used in an analogous manner for the evaluation circuit 29.

As the above explanations show, the adjustable power depends on the driving device and not on the lights.
