  • 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.
  • the operating element and the luminous means are arranged within a unit or connected to one another via installation lines. If the control unit and the lamp are separated, several (at least four) installation cables are required, which requires a relatively high installation effort.
  • the pulse width modulation PWM usually used for LED brightness controls generates a non-negligible radio interference spectrum when using installation cables several meters long.
  • the invention has for its object to provide an optimized method for controlling a lamp.
  • the achievable with the present invention consist in particular in that the full waves of the mains voltage can be used as quasi as communication time slots for the information signals.
  • 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 transfer from the drive unit to the luminaire is DC-free, ie the conditions for an AC voltage are met at all times, in particular the installation lines are not subjected to pulsating direct currents.
  • 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 supply of the luminaire is continuously supplied with full mains voltage, interrupted only by the very short time periods during which information power waves are generated in order to change the brightness and / or light color of the luminaire. Accordingly, a good efficiency results.
  • the EMC load electromagtic compatibility
  • the operation by means of actuation of the drive device is simple and clear.
  • the power supply, the control module and the power module of the lamp 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).
  • the drive device for generating an information power wave can influence the phase angle of the mains voltage during this wave.
  • the control module can determine the current flow time occurring during a particular information power 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 three full waves of the mains voltage following the synchronization signal can serve as information grid waves for the transmission of separate brightness information signals for the red respectively green respectively blue light color.
  • the information grid waves can be transmitted repeatedly. At least one additional full wave can be inserted between the synchronization signal and an information network wave and / or between two information network waves in order to effect a recharging of capacitors of the power supply.
  • Fig. 1 is a schematic diagram of a preferably connected via at least one installation line to a control unit, a plurality of light sources (preferably LEDs) having different color having light.
  • the drive unit 17 (operating unit, operating element) is connected on the input side to phase L and neutral conductor N of an AC voltage network 15 (230 V AC voltage).
  • the output side tapped at the drive unit 17 output voltage is hereinafter referred to as conditioned phase L 'and corresponds to the input voltage of the lamp 1.
  • the lamp 1 is further connected to the neutral conductor N.
  • 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. On the output side, the control module 4 is connected to the base terminals of the transistors 5, 6, 7.
  • controllable semiconductor components or semiconductor switches can be used instead of the transistors shown by way of example.
  • Fig. 2 a circuit with several lights is shown.
  • Two luminaires 1, 13 designed as RGB LED luminaires can be recognized, which are connected via an installation line to the processed phase L 'of the drive device 17 and to the neutral conductor N. Of course, more lights can be provided.
  • a parallel connection of several lights is to reach the maximum load capacity of the drive unit 17, total power z. B. 400 W, possible.
  • the drive unit 17 is in turn connected to phase L and optionally also to the neutral conductor N of the AC voltage network 15.
  • 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.
  • 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 for a short time such that the connected lamp 1, 13 receives the information for its desired brightness from the temporal, from the control unit 17 forced voltage waveform in the form of the processed phase L 'is transmitted.
  • 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 connected lamps 1, 13 can detect this influence by means of their control components 4 and convert them via the correspondingly controlled power modules into the corresponding desired brightness and / or light color.
  • the drive unit 17 blocks its output voltage L 'completely, which has the advantage that no stand-by losses in the lamp arise when the lamp is switched off.
  • the values set for the brightness and the light color of the lamp during the last switch-off are expediently adopted by the control module and adjusted by means of the power module.
  • Fig. 4 is the phase characteristic in a control example "red LED OFF / green LED 50% control / blue LED 100% control" shown.
  • Fig. 5 is the phase characteristic in a control example "red LED OFF / green LED 100% control / blue LED 100% control" shown. Again, the below apply Fig. 3 explained specifications.
  • Fig. 6 is the phase characteristic in such an alternative driving example Fig. 3 with "red LED off / green LED 50% control / blue LED off” shown.
  • Fig. 3 explained definitions, wherein each an additional full wave W between the synchronization signal T sync and the communication time slot T R , between the two communication time slots T R and T G and between the two communication time slots T G and T B can be seen.
  • These inserted solid waves W are advantageously used to recharge the charging capacitors of the power supplies.
  • the control module 22 connected to the base of the transistor 23 receives the processed phase L '.
  • drive unit 17 are also used for this embodiment, which has the advantage that with a drive unit 17 both monochrome lights and as (multi-colored) RGB LED lights trained luminaires can be controlled.
  • illuminant (LED) 25 each of the same color
  • these luminous means are preferably connected in series, so that the power supply unit 21 requires only one transistor output.
  • the control module 22 only pays attention to the first information network wave after the occurrence of the synchronization signal T sync , ie the communication time slot T R , while ignoring the information of the following information network waves.
  • the phase angle of the first information power wave after the synchronization signal T sync accordingly indicates the desired brightness information signal of the light-emitting means (LED) 25. Accordingly, the drive of the transistor 23 via the pulse width modulation, as also explained above.
  • Fig. 8 a schematic diagram of a lamp is shown with the use of potential-free phase detection, which in all embodiments according to the FIGS. 1 . 2 . 7 Can be used.
  • an optocoupler 27 is connected in series with the series resistor 26 on the primary side between the processed phase L 'and the neutral. On the secondary side, the optocoupler 27 is connected between the negative output of the power supply 3 or 21 and the intended for the phase detection input of the control module 4 or 22.
  • the drive unit 17 is connected to the neutral conductor N.
  • the supply of the lamp 1 can also be done via the circuit in the flush-mounted insert 2. This is very advantageous when retrofitting an existing lighting, since a conventional light switch can be exchanged for the control unit 17 in a simple manner. In the flush-mounted box of a standard light switch, there is no neutral N in most cases.
  • the adjustable power depends on the driving device and not on the lamp.
