Fig. 1 shows the circuit diagram of a lighting device, and this lighting device preferably is connected on the controller by at least one wiring route, and this lighting device is provided with the light fixture (being preferably LED) of a plurality of different colors.The input of controller 17 (operator, executive component) connects the phase line L and the zero line N of AC power 15 (230V alternating voltage).The output voltage that obtains at the output of controller 17 is expressed as rectification phase line (aufbereitetePhase) L ' hereinafter, and this output voltage is equivalent to the input voltage of lighting device 1.In addition, lighting device 1 is also connected on the zero line N.
The lighting device 1 that is made of RGB-LED lighting device (R=is red/G=is green/B=indigo plant) comprises two primary clusterings or the functional unit that fits together, promptly, build-in components 2 and a plurality of light fixture (being preferably LED) 9,10,11, wherein, these two primary clusterings removably interconnect by the plug-in connector that corresponds to each other.
Build-in components 2 is provided with a power supply 3 (AC/DC frequency converter) that comprises charging capacitor at input, this power supply is powered by rectification phase line L ' and zero line N, the cathode output end of this power supply (direct current or direct voltage) connects the emitter terminal of transistor 5,6,7, transistor 5 is used for the particularly feed of red LED 9 of red light fixture, transistor 6 is used for the particularly feed of green LED 10 of green light fixture, and transistor 7 is used for the particularly feed of blue led 11 of blue light fixture.Transistor 5 or 6 or 7 collector terminal connect the anode terminal of LED 9 or 10 or 11.The cathode terminal of three LED 9,10,11 is connected on the cathode output end (direct current or direct voltage) of power supply 3.
Certainly, for example shown in transistorized position on, can also adopt other controlled semiconductor element or semiconductor switch.
For the operation of the controller 17 that adopts control lever, the described possibility of the document EP 1575341B1 that begins to mention can realize by the swing/rotation/pushing of described control lever, for example,
-Spin Control bar, thus brightness changed;
-control lever is swung on the different positions, thus the intensity of different color channels regulated;
-push control lever rapidly, or control lever is remained on the fixed position for a long time, thus determine thus closed/open/preserve needed value.
The circuit that is provided with many lighting devices has been shown among Fig. 2.Two lighting devices 1,13 that are made of the RGB-LED lighting device shown in the figure, these two lighting devices are connected with the rectification phase line L ' and the zero line N of controller 17 by a wiring route.The lighting device that can also connect other certainly.The parallel connection of many lighting devices can arrive controller 17 maximum load capability, and for example gross power is 400W.Controller 17 is connected on the phase line L of AC power 15, preferably is also connected on the zero line N of AC power.
The most basic is, every lighting device 1,13 all is provided with an independent power supply 3, and the power of this power supply is enough to satisfy the power supply of at least three light fixtures (LEDs) 9,10,11, and each LED for example is 1W.These three light fixtures (LEDs) 9 or 10 or 11 are triggered by the pulse width modulation with constant current (Pulsweitenmodulation) by transistor 5 or 6 or 7.Can provide different power to light fixture (LEDs) 9,10,11 by pulse width modulation.Can be implemented in the constant photochromic brightness of generation down thus changes.
In addition, the influence of going up the phase line traffic control by means of the time by controller 17 realizes the required brightness and/or the required photochromic adjusting of illumination apparatus 1,13, thereby can make controller 17 be otherwise known as " special dimmer ".Change as required in brightness and the photochromic process operating personnel, like this short time influences supply voltage U on the output lead (being expressed as L ') of this controller to controller 17 just, promptly, to pass to the lighting device 1,13 that is connected with the form of rectification phase line L ' from the information voltage characteristic curve, that be used for required brightness, this voltage characteristic curve be in time and order about by controller 17.
Near before the generation that arrives the voltage characteristic curve and calculating, at first should the basic concept of the information transmission advised be described.A kind of dimmer of common general knowledge is output as the user who is connected at it usually phase line section voltage (Phasenanschnittspannung) or the cross-section voltage of phase line (Phasenabschnittspannung) is provided.According to the phase line angle, brightness either large or small on the lighting device that is connected is regulated.Different therewith is, " the special dimmer " of being advised, and just controller 17, and the most of the time produces sinusoidal voltage fully insusceptibly.Only be for the brightness that changes lighting device and/or photochromic, that is to say that controller 17 voltage to its output in the time period that limits rapidly exerts an influence, and produces rectification phase line L ' thus in the time of operating personnel's operation control 17.The lighting device 1,13 that connects can detect described influence by the control module 4 of himself, and can convert corresponding required brightness and/or photochromic to by corresponding controlled power model.
In order to realize synchronously (noting: not only refer to the transmission energy from this, also refer to additionally transmit information), controller 17 has locked the complete all-wave of supply voltage U---referring to the synchronizing signal T shown in following Fig. 3-6
SyncThe charging capacitor of the power supply 3 in the lighting device 1,13 that connects takes advantage like this, that is, can the time upward be eliminated voltage fluctuation by this charging capacitor, and can not take place because voltage fluctuation makes the user perceive the situation of interference.Yet control module 4 recognizes synchronizing signal T
Sync, and beginning to start handling procedure, this handling procedure calculates three ensuing all-waves of supply voltage U, hereinafter referred to as information electrical network ripple (Informations-Netzwellen).
In these information electrical network ripples, controller 17 influences by the short time to the phase line angle and is provided for three kinds of photochromic brightness, and for example provides so just, that is,
● at synchronizing signal T
SyncThe phase line angle of first information electrical network ripple is afterwards represented the required brightness of red light or red light fixture (LED) 9;
● at synchronizing signal T
SyncThe phase line angle of second information electrical network ripple is afterwards represented the required brightness of green light or green light fixture (LED) 10;
● at synchronizing signal T
SyncThe phase line angle of the 3rd information electrical network ripple is afterwards represented the required brightness of blue light or blue light fixture (LED) 11.
The calculated example of the phase line angle of being surveyed by control module 4 for example limits this like this as obtaining by information electrical network ripple being formed the calculating that produces the time of electric current in the process, that is,
● the 1ms current time is corresponding to output (AUS) state or 0% control of related transistor;
● the 10ms current time is corresponding to input (EIN) state or 100% control of related transistor;
● current time is selected and the corresponding linear median of control under the situation between 1ms and the 10ms, and just 5ms is expressed as 50% control therewith adaptably.
Certainly, in this relation, it also is feasible selectively adopting other scheme.Importantly, make and detect required brightness by phase line angle or current time and be respectively each light fixture (LEDs) and be kept in the control module, so long as the control one of each light fixture (LEDs) produces, just up to one of controller 17 upgrade operation till, and produce updated information electrical network ripple thus.In order to improve the repetition that redundancy can also realization information be transmitted, this is to repeat because information electrical network wave energy is enough carried out one or many.Adapt therewith, voltage is not affected once more, pre-determines out next lighting device brightness and/or photochromic required variation up to controller.
In order to disconnect lighting device, controller 17 stops its output voltage L ' fully, and its advantage is not have idling consumption to produce in lighting device in the lighting device that disconnects.
In the connection process of lighting device, the operation of the controller 17 by correspondence (connecting supply power voltage L ', N), on purpose make in last opening operation, generate, be used for lighting device brightness and/or photochromic value receives by control module, and regulate soon by power.
