Definitions
- the invention relates to a circuit arrangement for cyclical activation of several consumers, with one Basic circuit that contains an oscillator and on several outputs successively generated pulses, the oscillator being a frequency-determining component having.
- Circuit arrangements with which consumers are known cyclically controlled in the form of light emitting diodes are, for example used in displays or in jewelry.
- the LEDs are controlled by a basic circuit, which, for example, as an integrated circuit, like the "Five Lamp / LED Flash Driver" HT 2051 the Holtek, is trained.
- the basic circuit points several outputs to which different LEDs be connected.
- the Basic circuit at the outputs cyclically pulses, so that the LEDs connected to different outputs illuminate cyclically.
- the repetition frequency with which the LEDs are activated depends on the value of a frequency-determining component that is externally connected the integrated circuit is connected. Here it is usually a resistance.
- the repetition frequency is low, and the value of the resistance is low, the repetition frequency of the pulses is high.
- All LEDs are used for the type of control Triggered pulses of the same duration. Have the LEDs different colors, so there are different Luminosity because the effectiveness, e.g. a blue light emitting diode, is less than that a red LED. The blue LEDs light up therefore less powerful than the red LEDs.
- DE-OS 40 00 954 is a programmer with selectable Duty cycle of lined up, the Program sequence defining impulses with electronic Counters and decoders disclosed.
- the width of the impulses can optionally by changing the resistance of the RC elements in the pulse generator are modified, whereby the pulse train generated in this way to a single output is issued. So within a program run created a large number of modifications that are of the different width of the Individual pulses and the number of individual pulses depends. A cyclical activation of several consumers, whereby assigned a certain amount of energy to each consumer is not described.
- the invention has for its object a circuit arrangement for cyclical activation of several consumers to create, which makes it possible with simple means that the individual consumers during a Control pulse supplied power individually dimensioned and thereby e.g. different efficiencies to balance the consumer.
- the circuit arrangement according to the invention is based on Principle on known circuits that the individual Control consumers with pulses of the same length.
- the frequency-determining component that determines the oscillator frequency, assigned a switch, with which the oscillator frequency changes temporarily can be, namely when the switch in the conductive state.
- This switch is used by the Outputs of the basic circuit controlled. So it is possible, for example an output of the basic circuit not to connect to the switch, so the Pulse generated at this output, the oscillator frequency not changed. Another exit of the Basic circuit can, however, be connected to the switch his. If there is a pulse of ground potential at this output occurs only for the duration of this pulse the oscillator frequency increases, causing the pulse sort of shortened itself.
- LEDs different colors for example the blue LEDs with a pulse duration operated that the normal (unchanged) Oscillator frequency corresponds to those Pulses that control the red LEDs at the same time increase the oscillator frequency and thus the pulse durations shorten the red LEDs. In this way it is achieved that the red LEDs are less electrical Power is supplied as the blue LEDs.
- the blue LEDs are a lot lower electro-optical and visual efficiency have than the red LEDs, both types appear of LEDs about the same brightness.
- the switch with which the oscillator frequency is changed, the frequency determining Component connected in parallel with a resistor.
- a preferred embodiment of the invention provides that the switch is switched as a current source is.
- Such a switch consists of a transistor in basic basic circuit. This transistor is used by the Output pulses of the basic circuit controlled and he generates an amperage that is unique to that particular Output that is currently activated depends. In this way, the duration of each pulse, with which the consumers are controlled, individually influenced, the oscillator its normal Fundamental frequency always assumes when the corresponding one Output pulse is ended.
- the usual circuit arrangements for driving LEDs generate pulses with a duty cycle of 1: 1, the pulse length being as long as that Impulse pause.
- This duty cycle is achieved by the invention individually changed.
- the invention is also the frequency determining Component a diode connected in parallel. This diode causes an additional change in the duty cycle, by shortening the pulse pauses.
- the circuit arrangement has a basic circuit 10 on, preferably as an integrated circuit is trained, e.g. the "Five Lamp / LED Flash Driver "HT 2051 from Holtek.
- This Basic circuit includes one Oscillator 11 with an inverting cut trigger 12, whose output via a resistor 13 on the Input is fed back, the amplifier input is also connected to a capacitor 14.
- the feedback branch of the cut trigger 12 is in series with the resistor 13 a frequency-determining component 15 provided in the form of a resistor that is external to the basic circuit 10 is connected to the consumer the fundamental frequency of the oscillator 11 by Choice of an appropriate resistance can set.
- the basic circuit 10 also has a plurality of outputs A1-A5 on. Each of these outputs is through a transistor T1-T5 controlled, a negative at this output Impulse (ground potential) sets when it is in the conductive State is controlled.
- the transistors T1-T5 are controlled by the oscillator circuit 11 one after the other, the transistor T1 providing a pulse, then an impulse pause of the same duration occurs, and the Transistor T2 provides a pulse, etc.
- the circuit arrangement described so far is known. It delivers pulses at the outputs A1-A5 equal durations, with the pulses at the outputs A1-A5 follow each other cyclically and then output A1 is activated again at output A5.
- the frequency-determining component 15 which is a resistor here, a switch 18 connected in parallel.
- the switch 18 is a transistor its emitter with one end and its collector with the other end of the frequency-determining component 15 is connected.
- the base is with resistors R1-R4 connected, of which the resistor R1 to the output A1, resistor R2 connected to output A2 etc. is.
- There is no corresponding one for output A5 Resistance is provided, i.e. Output A5 can do not control switch 18.
- the base of the switch 18 is also via a diode 22, which is the same as the emitter-base diode of the Switch 18 is switched, and a resistor R20 connected to the positive pole of the supply source 17.
- Resistor R1-R4 together with the resistor R20 a voltage divider through which a certain potential placed at the base of the switch 18 and this Switch is controlled in the conductive state.
- the Switch 18 forms together with the resistors mentioned R1-R4 and R20 a current source 19 which one Constant current supplies, the size of which is equal to the value of relevant resistor R1-R4 depends.
- the diode 22 serves the voltage drop of the emitter base diode of the switch 18 to compensate for that normally is not conductive.
- the resistors R1-R4 can be selected appropriately Pulse durations with which consumers L1-L4 are controlled be influenced individually.
- the switch 18 has a diode 21 connected in anti-parallel, i.e. connected in parallel with a polarity that that of the emitter-base diode of the switch 18 is opposite. This diode 21 shortens the pulse pauses between the pulses to almost zero, so that the pulses generated at the outputs A1-A5 be able to follow one another in immediate succession.
