Description

The The invention relates to a dimmer system with multiple multidimmers and on a multidimmer according to the preamble of claim 2, which universally as a master dimmer as a slave dimmer or can be used as an extension.

From the DE 100 25 368 A1 is a dimmer for brightness control of lighting devices having a power switch for switching a load circuit within a dimming phase angle range, adjusting means for adjusting a dimming phase angle, and control means for driving the power switch in response to a dimming phase angle set by the setting means or a transmitted one Dimming control command known. A control input of the dimmer exchanges bidirectional dimming control commands with additional dimmers. The different dimmers have equal rights and can send and receive dimmer control commands. The brightness can be set on any dimmer that sends the corresponding dimmer control commands to the other dimmers. The dimmer control commands contain information data regarding the desired phase angle. The dimmer can be connected in parallel with other identically constructed dimmers for power expansion to a common load or for simultaneous dimming of separate load circuits.

From the EP 0901 313 B1 a dimmer system for controlling lighting devices is known, which has a master dimmer and at least one slave dimmer, the master dimmer sets the brightness value via its processing and control device and the control signals formed in the processing and control device of the master dimmer power section of the master dimmer and also via control lines be supplied to all connected slave dimmers. The slave dimmer therefore require no processing and control device. The controlled power outputs of power units of all dimmers are connected together by electrical parallel connection to form a common controlled output (to which a load is connectable).

since Long are on-market bleed and section dimmer performance enhancements with circuit principles known from the load outputs of Masterdimmers generate the phase angle control for performance enhancements. Essentially, the current and voltage characteristics of the Load output of the master dimmer evaluated in the power extension and further processed for phase angle control of the power extension.

From the DE 103 15 554 B3 a dimmer module is known, with a programmable processing and control device for controlling a power section, which is the output side connected in parallel with a master dimmer. The dimmer module has a phase detector, by which the time course of the master half-waves can be determined. The processing and control device generates temporally shortened dimmer half-waves, which are connected in parallel to the master phase to the consumer. The dimmer module can be used both as a master dimmer and as a slave dimmer. By the phase detector and an upstream of the processing and control interface is checked whether there is a change in the voltage to the power lines or applied to the control lines, a drive signal. Accordingly, the dimmer module acts as a master dimmer or as a slave dimmer.

From the DE 10 2004 055 748 B3 is a dimmer arrangement, consisting of a control dimmer and at least one parallel dimmer power addition known thereto, wherein a circuit of measured values of a voltage sensor and a current sensor, the zero voltage crossing, the current zero crossing and switching and control operations of the control dimmer due to variations in voltage and load voltage preset and current waveform recognizes, evaluates and immediately triggers appropriate switching or control operations in the associated load switch.

Of the Invention is based on the object, a dimmer system with several Multidimmers and a multidimmer specify which one universal the function of a master dimmer or a slave dimmer or a Substitute on the fly, and so the change the brightness of the (common) load can trigger.

• – wobei eine Bedienung an einem beliebigen Multidimmer automatisch zur temporären Übernahme der Funktion als Masterdimmer führt, wodurch das Steuersignal des Bedienelementes den aktuellen Sollwert für das Dimmersystem vorgibt und der Phasenwinkel dementsprechend in gewünschter Weise verändert wird,
• – wobei die weiteren Multidimmer des Dimmersystems über ihre Verarbeitungs- und Steuereinrichtungen die Differenz zwischen gegenwärtigem und neu eingestelltem Phasenwinkel erkennen, folglich automatisch und temporär die Funktion von Slavedimmern übernehmen und ihre Phasenwinkel nachregeln,
• – wobei ein Stromdetektor das Stromsignal des eigenen Lastanschlusses erfasst und der Verarbeitungs- und Steuereinrichtung zuleitet und Letztere das Stromsignal mit dem Signal eines Phasendetektors vergleicht, aus dem Verhältnis der Signale zueinander die eigene Abweichung vom eingestellten Phasenwinkel ermittelt und gegebenenfalls durch entsprechende Beaufschlagung das eigene Leistungsteil nachregelt.

This object is achieved with respect to the dimmer system according to the invention by a dimmer system with multiple mains and load side parallel multidimmers, which can automatically and temporarily take over the functions as a master dimmer, as slave dimmer and as an extension,

• - Wherein an operation on any Multidimmer automatically leads to the temporary takeover of the function as a master dimmer, whereby the control signal of the control element sets the current setpoint for the dimmer system and the phase angle is changed accordingly in the desired manner,
• - Wherein the other multidimmer of the dimmer system recognize the difference between current and newly adjusted phase angle through their processing and control devices, thus automatically and temporarily the function take over from slavedimmers and readjust their phase angles,
• - Wherein a current detector detects the current signal of its own load terminal and the processing and control device zuleitet and the latter compares the current signal with the signal of a phase detector, determined from the ratio of the signals to each other's own deviation from the set phase angle and optionally readjusted by appropriate application of their own power unit ,

The Task is in relation to the multi-dimmer in conjunction with the Features of the preamble according to the invention by in the plate of the Claim 2 specified features solved.

The particular advantages of the invention are that for example for 500 W designed multi-dimmer universal and without any additional Facilities as a main office (master dimmer), as a service extension (Additional power, slave dimmer) and as extension (only for Operation) can be used. Therefore all different applications one and the same multi-dimmer can be used, arise despite the more complex structure of the individual device Overall cost advantages, eg. B. lower order and logistics costs, simplified planning and installation for the installer.

In needed its simplest version the Multidimmer only has two connections, namely Phase and controlled phase. Optionally, control cables, operating inputs and the neutral conductor are connected.

It is in a simple way using two, three and more identical multi-dimmers in versions for flush-mounted, built-in or Distribution assembly possible, Multi-master dimming systems for centralized or decentralized control of lighting systems with large To realize connected services. Operation is via bus systems and / or remote controls and / or attachable controls and / or Extensions. A symmetrical distribution of the load current to all Parallel Multidimmer, d. H. a synchronous control is ensured. In contrast to other known master / slave systems is a distinction in master dimmer / slave dimmer no longer necessary, because each Multidimmer handles and controls the load can. The system can thus also have several local operations are operated on the multidimers, also PBX operation is unrestrictedly possible.

Also while the operation, the operation can be changed or yourself to change independently, d. H. a master dimmer turns into a slave dimmer or extension, a slave dimmer becomes a master dimmer or an extension, Your extension becomes a master dimmer or a slave dimmer.
