Definitions

  • the invention relates to a method for influencing or changing at least one parameter of a
  • control information in particular an LED lamp, by means of control information, wherein the control information is effected by means of an AC supply voltage which forms the power supply of the lighting means.
  • control information for dimming luminaires such as e.g. Powerline method, coding method using phase angle, short-term power interruptions "double click", radio controls, etc.
  • “Retrofit LED lamps” are to be understood as lamps that use one or more LEDs as the light source, but are designed for mechanical and electrical connection such that they can be used as a substitute for other bulbs, such as incandescent or halogen lamps.
  • the latter are provided with screw or base bases, which are compatible with the versions designed for incandescent lamps.
  • this mechanical adjustment alone is not sufficient for replacement. Because of the different ways of operating light bulbs
  • phase angle dimmers For lighting systems with conventional incandescent lamps, phase angle dimmers have largely prevailed. This is particularly because they work largely lossless and stable. However, the latter is not true for operation with LEDs. In order to limit the power losses and to ensure the functionality, a considerable additional circuit complexity is required. In addition, phase-angle dimmers - even when operated with incandescent lamps - inevitably radiate unwanted harmonics into the network. However, modern operating devices are expected to have a largely sinusoidal current consumption. This can be achieved by the additional installation of PFCs, which however further increases the circuit complexity. The basic load required by a phase-control dimmer must also be simulated by the operating device, which leads to undesirable losses and also to heat generation.
  • phase-angle dimmers for the dimming operation of LEDs is not an ideal solution.
  • the invention has for its object to design a method of the type described above so that it requires little effort in particular when used for dimming retrofit LED lamps, works largely lossless and practically no harmonics reflected back into the network.
  • the invention has the content that a signal transmission to a supplied with AC voltage electrical load, in particular a light source, is effected in that at least the signal states
  • the core idea of the invention is to modify the AC line 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.
  • This is achieved by changing the polarity of selected mains half-waves, more precisely, by reversing them.
  • the polarity of each second mains half-wave is reversed in a sequence of mains half-waves, so that the sequence consists only of mains half-waves of the same polarity. So it forms a pulsating in this phase DC.
  • Control information to be modified For example, the number of successive mains voltage half-waves of the same polarity or their total time length can be a measure of a degree of dimming. Additional information lies in the polarity of the modified mains voltage half-waves, which can be selected as positive or negative.
  • the polarity of a series of mains voltage half waves of the same polarity can, for example, a dimming direction or a
  • dimming speed A predetermined sequence of polarities of mains voltage half-waves can for example trigger a predetermined dimming jump. It is understood that the consumer must have appropriate means to evaluate the control information.
  • Figure 2 shows the circuit structure of a control gear
  • a load preferably a retrofit LED lamp
  • Figure 3 is a schematic representation of a
  • FIG. 1 a shows a sequence of mains half-waves with alternating polarity, as it provides the alternating current network.
  • the alternating voltage network N is supplied to a load L via an operating device 1.
  • the load L becomes powered by the AC mains N powered.
  • the AC voltage termination is the only interface of the operating device 1, as is the case, for example, with bulb sockets.
  • an externally accessible power switch S and a push-button T which is also accessible from the outside.
  • the button T acts on two pairs of contacts Tal / Ta2 on the one hand and Tbl / Tb2 on the other hand, in opposite directions. This means that in the illustrated idle state of the button T, the first pair of contacts Tal / Ta2 open and the second pair of contacts Tbl / Tb2 is closed. If the button T depressed against the force of a (not shown) spring, the first pair of contacts Tal / Ta2 is opened, and the second pair of contacts Tbl / Tb2 is closed.
  • the operating device further includes four rectifier diodes Dl, D2, D3, D4. These are so connected to the two contact pairs valley, Ta2 and Tbl, Tb2, that the load L are supplied with closed power switch S and not pressed button T, the mains half-waves as shown in Figure la, so with alternating polarity.
  • Figure lb now shows the case that the power switch S is closed at time tl and the button T is pressed a little later at time t2.
  • the switching operation is completed.
  • the contact pairs Tal / Ta2 on the one hand and the contact pairs Tbl / Tb2 on the other hand need a certain, albeit short, time in which the mains voltage is interrupted. However, this interruption is so short that it can be buffered away.
  • the representation of the power interruption in Figure lb is not to scale and in connection with the basic operation of the operating equipment of minor importance.
  • the button T is released again. From t3 to t4, mains voltage half-waves of the same polarity are now supplied to the load. After releasing the button T at the time t4 again followed by the switching of the pairs of contacts Tal / Ta2 on the one hand and Tbl / Tb2 on the other conditional short interruption of the mains voltage. From time t5 to the load, the mains voltage half-waves are again supplied with the specified by the network N polarity to the load L, ie with alternating polarity.
  • the temporal total length tges. T4-t3 of the series of mains voltage half-waves with the same polarity which can be determined by means of the push-button T determines the degree of influencing or changing of a parameter of the load L.
  • the parameter is the dimming degree or the brightness of a Retrofit LED lamp. It is understood that by reversing the circuit arrangement of the rectifier diodes Dl to D4 and the polarity of the mains half-waves between the times t3 and t4 can be reversed. So here is an additional degree of freedom for the transferred Control information that can be used, for example, to adjust the color of the 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.
  • the dimming direction of a dimming operation of the light source can be predetermined by the polarity of a sequence of mains half-waves of the same polarity. So can be successive
  • the upward or downward dimming can take place continuously and is continued, for example, as long as successive mains half-waves of the same polarity are generated. Continuously may mean that the same for each predetermined number of successive mains half-waves
  • Polarity of the dimming level is increased or decreased by a minimum possible dimming level.
  • control information about the number or the specific sequence of mains voltage half-waves of the same or different polarity is transmitted.
  • a first predetermined number of mains half-waves of the same polarity or a first sequence of mains half-cycles of alternating priority may activate up-dimming, another number or another sequence may enable down-dimming.
  • dimming jumps can also be coded by a specific number or a specific sequence of polarities of mains voltage half-waves or such a dimming jump can be triggered thereby.
  • Mains voltage half-waves could cause a non-continuous change in the degree of dimming by a first predetermined value.
  • a second predetermined combination of polarities could cause a non-continuous change in the degree of dimming by a second predetermined value.
  • Another way to exploit the different polarities of mains half-waves is to set a dimming speed. So could for example first determine a first sequence or number of polarities of line voltage half-waves, whether in the following an up-dimming or down-dimming is to be performed. Thereafter, for example, mains half-waves of a first polarity could perform a faster dimming operation, mains voltage waves of a second polarity a slower dimming operation. It is also conceivable to specify a specific sequence of polarities of mains voltage half-waves, which the
  • Dimming speed changed during a dimming process For example, a given first sequence could increase the dimming speed by a certain percentage or absolute amount, a second predetermined sequence could decrease the dimming speed by a certain percentage or absolute amount.
  • mains half-waves or polarities of mains half-waves it is also possible to use complex sequences or patterns of mains half-waves or polarities of mains half-waves to alter or configure operating parameters other than the brightness of a light source.
  • An example is the color or color temperature of the light source.
  • Another example would be an adjustment of whether the light is emitted continuously or pulsed from the light source.
  • the button is only as an example of a signal generator which is manually operated (for example, a switch, rotary dimmer, etc.) or non-manual control signals an interface gets supplied or this generated itself (eg. Sensor, such as. Daylight sensor, color sensor, etc.).
  • a button and a relay can be used, which is triggered for example by a button.
  • This signal generator is basically designed to selectively rectify a supplied bipolar AC voltage, which he further grids as a supply voltage to one or more operating devices, rectified.
  • 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, selective addressing can also be used to carry out an addressed grouping of the lamps.
  • 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.
  • Illuminants in particular LEDs of different colors
  • Phase control dimmer and when 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-control dimmers can easily be used against operating devices
  • Figure 3 also shows the basic structure of a retrofit LED lamp. This consists of a screw base
  • the screw 2 is suitable for a version 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 arrow 9 indicates that and how the alternating voltage half-waves are forwarded to a driver circuit 6 located in the lamp. This will be explained in more detail later in connection with FIG.
  • the driver circuit 6 generates a DC voltage, which - as indicated by the arrow 10 - is supplied to an LED module 7, on which sit the light emitting LEDs 8.
  • 4 - but still schematically illustrated - driver circuit 6 includes an AC / DC converter 11, a DC / DC converter 12 and a polarity sensor 13 to which the mains voltage half-waves shown in FIG , In the first phase between tl and t2, the AC / DC converter 11 rectifies the mains voltage half-waves of alternating polarity and supplies a pulsating DC voltage consisting of sinusoidal
  • the polarity sensor 13 determines that the device supplies mains halfwaves of similar polarity.
  • the polarity sensor 13 reports this to 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 therefore corresponds to the number of line voltage half-waves changed in terms of their polarity or their total time length.
