- the core idea of the invention is to modify the AC mains voltage, here also referred to as AC voltage, which in any case must be supplied to the consumer for its operation in such a way that it contains the control information for influencing or changing at least one parameter of the consumer.
- AC voltage AC mains voltage
- This is achieved by selectively applying only voltage halfwaves (mains half-waves) of one polarity to the load for evaluation.
- mains half-waves voltage halfwaves
- the intervening half-waves are filtered out in the operating mode.
- the half waves of one polarity then generate a pulsating DC voltage.
- control information By determining the number of half-waves in the said sequence or the total time length thereof, the control information can be modified. Additional information lies in the polarity of the half-waves, which can be chosen as positive or negative. It is understood that the consumer must have appropriate means to evaluate the control information.
- the method works practically without interference, i. without the reverberation of harmonics in the AC mains.
- the energy storage is designed to store the necessary energy to compensate for the missing half-waves.
- the circuit complexity for implementing the method is relatively low, so that the costs can be kept low.
- FIG. 1 shows by way of example an AC voltage and a one-way rectified (pulsating) DC voltage.
- Fig. 2 is an evaluation of different types of voltage
- FIG. 3 shows schematically an embodiment of a
- Figs. 4a and 4b possible waveforms for the AC voltage and resulting voltage half-waves.
- 5a and 5b schematically each a further embodiment of a circuit according to the invention.
- FIG. 6 is a schematic representation of an operating device block with an external one
- Fig. 7 is a schematic representation of a
- the AC voltage (AC voltage) is applied to a load, e.g. an LED module or a retrofit LED lamp, fed via a phase conductor.
- the load is powered from the phase conductor.
- the consumer may be an LED module or a LED track and in particular is a retrofit LED lamp.
- phase conductor-load neutral conductor (neutral, ground) is on the phase side of the consumer an actuator, preferably a dimming switch and optionally a switch (power switch) provided in series. Parallel to the actuating element, a diode is connected, which can be selectively bridged by the actuating element.
- the consumer is supplied with an AC voltage with half-waves of alternating polarity. This is shown, for example, in Fig. 4a above. If, for example by actuation of the actuating element, the bridging is canceled, for example by the actuating element being depressed against a force of a spring (not shown) and a pair of contacts Tal / Ta2 being opened, then only one half-wave supply of one polarity, for example positive polarity ( as shown for example in Fig. 4a below).
- the AC voltage termination is the only interface of the operating device of the consumer, as is the case, for example, with bulb sockets.
- the switch and the actuator can be connected to the operating device or integrated in this and accessible from the outside.
- the consumer After a reset of the actuating element, for example after releasing the actuating element, and closing the pair of contacts Tal / Ta2, the consumer again the AC voltage half-waves are supplied with the predetermined polarity of the network, ie with alternating polarity (see Figs. 4a and 4b each at the top).
- the total length of the sequence of voltage half-waves with the same polarity that can be defined by the actuating element determines the degree of influencing or the change of a parameter for the operation of the consumer.
- the parameter is in particular the dimming level or the brightness of a retrofit LED lamp. For example, it can be evaluated by the operating device of the retrofit LED lamp that the operating parameter is continuously or gradually changed with increasing length.
- the control information may also be used, for example, to adjust the color of the consumer / lamp to be controlled. Another way to transmit additional control information is to repeat the sequence of mains half-waves with the same polarity, with a certain repetition rate.
- Fig. 5a shows a further embodiment of a circuit according to the invention.
- selectively either the voltage half-waves of one or the other polarity can be filtered out.
- the two actuators are designed so that a simultaneous operation is not possible.
- the actuators can be summarized eg in a rocker switch. However, it can also be provided that a simultaneous actuation is possible, and by simultaneous operation, the function of a power switch is realized.
- the actuator and the switch is replaced by an integrated power and dimmer switch.
- the integrated mains and dimmer switch can here, in particular between the states off, ie no voltage is supplied to the consumer, on, ie the consumer is supplied with the AC voltage, and dim, ie the consumer is operated with voltage halfwaves of only one polarity, to get voted.
- the consumer can switch to a mode in which the lighting means is successively dimmed and dimmed again until the dimming process is terminated, for example, when it is switched back to the on position, and thus a dimming value, or a brightness value, is set with which the light source is operated.
- the integrated power and dimmer switch has three states. Depending on the position of the integrated power and dimmer switch, it is in the Off state, i. interrupts the power line. In the ON state, it directly connects the phase conductor to the load, i. the load is supplied with the AC voltage.
- the state Dim in which consumers are operated with voltage half-waves of only one polarity, is achieved in that here the integrated power and dimmer switch is in a position in which the phase conductor is connected via a series connection with a diode to the consumer.
- the connection between phase conductor and load can be made here via two parallel branches by means of the integrated power and dimmer switch, depending on the switch position either a direct connection or a connection is made via a diode.
- the actuator is only as an example of a signal generator which is manually / automatically operable (eg., A switch, button, rotary dimmer, etc.) or non-manual control signals supplied to an interface or generates this itself (eg., Sensor, such as. Daylight sensor, Color sensor etc.). It can also be used a relay, which is triggered for example by a button.
- a signal generator which is manually / automatically operable (eg., A switch, button, rotary dimmer, etc.) or non-manual control signals supplied to an interface or generates this itself (eg., Sensor, such as. Daylight sensor, Color sensor etc.). It can also be used a relay, which is triggered for example by a button.
- This signal generator is basically designed to selectively a supplied bipolar AC voltage he as supply voltage to one or more
- Operating gear continues to selectively disposable rectified.
- arbitrarily complex signals or data can be transmitted to the operating device.
- the signal generator can be connected externally or internally in the operating device.
- the signal transmitter is functionally connected to several lamps which belong to one or more operating devices, can be carried out on the selective disposable rectification also addressed grouping of the bulbs.
- the signal states mentioned are then recognized by one or more connected operating devices in the sense of addressing. It can thus set up an addressed bus system. Possible groupings are, for example:
- Illuminants in particular LEDs of different colors
- a control unit is provided, which is realized by an evaluation (eg microcontroller and / or ASIC).
- the control unit can thus detect the states "regular AC supply voltage” or “one-way rectified AC voltage” and possibly also the polarity of the rectification, in order then to further forward the AC voltage to the energy supply and secondly a control signal depending on the detected signal state to create.
- this control signal is a dimming signal.
- up and down dimming may be performed cyclically during rectification until the user stops manual operation and thus one-way rectification again.
- the duration of the rectification can also be evaluated.
- the simplest state is cyclical up and down dimming for the duration of the rectification.
- a short period of one-way rectification could mean a first signal state and a longer period of one-way rectification a second signal state.
- Phase control dimmers in existing lighting systems should be replaced with retrofit LED lamps and matching control gear as far as possible without additional circuitry. This is possible if the housing of the operating equipment externally the same dimensions as that of the Phasenanterrorismsimmer, and if the button T and the power switch S are accessible from the outside. A change of the wire installation is then usually unnecessary.
- the phase angle dimmers can be easily exchanged for operating devices 1, as shown in Fig. 6.
- the operating device 1 also has the following advantages. It does not generate any power loss and does not radiate harmonics back into the alternating voltage network N. Because it is built on switch contacts, it can be cost effective getting produced. The simulation of a basic load is not required.
- Fig. 6 also shows the basic structure of a retrofit LED lamp.
- This consists of a screw base 2 and a glass bulb 3.
- the screw base 2 is suitable for a socket of a corresponding light bulb, which is to be replaced by the retrofit LED lamp.
- the metal screw thread and the end pole form connection contacts, via which the Retrofit LED lamp from the operating device 1, the AC half-waves are supplied.
- the driver circuit 6 generates a DC voltage, which - as indicated by the arrow
- the driver circuit 6 shown somewhat more in detail but nevertheless schematically illustrated includes an AC / DC converter 11, a DC / DC converter 12 and a polarity sensor 13, to which the mains voltage half-waves are supplied by the operating unit 1.
- the AC / DC converter 11 directs the AC / DC converter 11 in a first phase.
- Mains voltage half-waves of alternating polarity equal and provides a pulsating DC voltage consisting of sinusoidal mains half-waves of the same polarity to the DC / DC converter 12. This reduces the DC voltage to a value suitable for the LEDs 8 and leads them to the LED module 7, on which the LEDs 8 sit.
- the polarity sensor 13 reports this e.g. a timing device 14, which measures the total time length of this phase.
- the measurement result is transmitted to a control unit 15, which generates a dimming signal therefrom.
- This is fed to the DC / DC converter 12, whose output signal is varied accordingly.
- the brightness of the retrofit LED lamp accordingly corresponds to the number of recognized in terms of their polarity mains voltage half-waves or their total time length. This can be set on the operating device 1 by correspondingly short or long pressing of the button T. However, by pressing the T button, the power transmission between the operating device 1 and the load L, i. the retrofit led lamp, untouched.
