Definitions

  • the invention relates to an operating device for operating lamps, in particular LED lamps, and to a method for controlling a lamp with the aid of the operating device.
  • the operating device converts the supply voltage into a voltage and power supply adapted to the respective illuminant, for example and in particular an LED or a plurality of LEDs. This adjustment can also be made variably, i.e. Settings can be made with the aid of which the illuminant can be dimmed, for example, or can be adapted with regard to the emitted color spectrum.
  • Usually separate control devices are used to interact with the control gear.
  • the operating device has control connections via which the command signals are received. It becomes problematic when such lamps, which require an operating device, are used in exchange for conventional lamps, for example light bulbs. Usually there is no control line on the building side and retrofitting is correspondingly expensive.
  • lamps have been developed in the past in which the control gear is housed in a screw base. This means that the illuminant and the control gear are integrated together in a lamp similar to an incandescent lamp.
  • a separate control line is of course not available in such a case. Therefore, possibilities have already been created in the past to also transmit information to the operating device via lines with which a voltage and power supply takes place.
  • Such a system is for example from the DE 10 2012 206 056 A1 known. It is described here that the pulsating supply voltage is a Information can be impressed, for example by temporarily rectifying the AC voltage. As an alternative, it is also described to use phase gates or phase segments. In principle, any change in the voltage curve can be used to transmit information as long as the receiving side, in this case the operating device, is able to recover the information.
  • a current flow is generated via a measuring resistor and the associated voltage drop is measured.
  • Different voltage drops at the measuring resistor are generated for the positive and for the negative half-wave of the supplied supply voltage, since two resistors of different dimensions are provided between the L-wire and the N-wire.
  • the center of these two resistors is connected to the measuring resistor in order to generate the current flow already described.
  • only one of the two resistors is in series with the measuring resistor in the current path.
  • phase sections or phase sections cannot always be carried out reliably. Interferences, such as those caused by parasitic capacitances, in particular in the region of the zero crossing of the pulsating supply voltage, make it difficult to reliably detect a phase cut.
  • the US 2013/320880 A1 discloses an RMS voltage converter for LED lights.
  • the US 2010/072903 A1 discloses color and intensity control over power cables.
  • the CN 2016/39823 U discloses a PWM chopper LED driver circuit.
  • the WO 2014/176617 A2 discloses a control device for a lighting device, a programming device and a method for configuring the control device.
  • Phase section of the supply voltage is impressed.
  • the operating device according to the invention and the method can also readily recognize, for example, the transition from a pulsating supply voltage to a DC voltage. This can occur if, due to a power failure, a switchover to an emergency power supply takes place, which is generally operated from an accumulator or a battery and thus feeds a DC voltage into the supply network. A targeted switching of polarities in the pulsating voltage supply can also be recognized.
  • the object of the invention is achieved by an operating device according to claim 1 and a method according to claim 2.
  • the operating device has a first input connection and a second input connection. By means of these connections, the operating device can be connected to a pulsating supply voltage source in order to supply the operating device with electrical power, with which a lamp connected to the operating device can be supplied.
  • the operating device also has detection means which enable separate detection of a first voltage, that of a positive half-wave, and a second voltage, which corresponds to a negative half-wave of the supply voltage.
  • the measurement signals generated by the detection means on the basis of the first voltage and the second voltage are used for further determination of the information. For this purpose, an evaluation unit is provided for evaluating these measurement signals.
  • a first voltage divider is now arranged between the first input connection and a ground potential of the operating device as detection means and a second voltage divider is arranged between the second input connection and the ground potential.
  • a first measurement signal for the first voltage is generated with the aid of the first voltage divider and a second measurement signal for the second voltage is generated with the aid of the second voltage divider.
  • the measurement signals are the voltages tapped at the respective center points of the voltage dividers. These are fed to the evaluation unit.
  • the advantage of the described procedure is that two independent signals are present, each signal being assigned to a half-wave of the supply voltage. The difference between these two signals enables an exact representation of the original supply voltage to be obtained.
  • parasitic capacitances therefore do not have a negative effect. The robustness of the detection is thus considerably improved, in particular when using phase gates or phase segments for the transmission of information to the operating device.
  • each input signal being assigned to a half-wave of the pulsating supply voltage.
  • a difference signal is then formed in the evaluation unit.
  • the further evaluation can then take place on the basis of this difference signal, it being particularly advantageous that the signal errors described can be avoided by parasitic effects, in particular in the region of the zero crossing.
  • rectification of the difference signal is preferably carried out.
  • the processing carried out in the evaluation unit is preferably carried out digitally, for which purpose the two measurement signals are digitized before further processing, in particular before the difference signal is formed.
  • the rectified difference signal is fed to a comparator, an integrating circuit or a differentiating circuit.
  • the information which was impressed on the supply voltage supplied to the operating device can be recognized more easily in the control unit.
  • the resulting waveforms are characteristic of the imprinted information and are made visible with the aid of the comparator, the integrating circuit or the differentiating circuit.
  • retrofit LED lamps which can replace e.g. of incandescent lamps or halogen lamps.
  • retrofit lamps have connection bases with which they are introduced into known lamp holders, e.g. screwed or plugged in.
  • the invention can always be used when information is to be transmitted to an operating device, but only supply lines are available for the transmission of the information. Of course, this can also be the case with an external control gear.
  • LED lamps have one or more LEDs, at least one of which emits white light, preferably with color conversion.
  • white LED preferably with color conversion.
  • monochromatic LEDs preferably emitting in the red spectrum, may also be present.
  • the retrofit LED lamp L comprises a screw base 2, a glass bulb 3 and lamps, for example one or more inorganic LEDs or OLED lamps 8.
  • lamps for example, one or more inorganic LEDs or OLED lamps 8.
  • Other lamps such as, for example, halogen lamps or gas discharge lamps, can also be operated by the operating device.
  • the screw base 2 is suitable for a version of a corresponding incandescent lamp, which is to be replaced by the retrofit LED lamp L.
  • a metal screw thread 5 and an end pole 4 of the lamp L form connection contacts via which the retrofit LED lamp L is supplied by a signal generator 1 with a supply voltage Vmains.
  • the supply voltage Vmains is generated on the basis of the mains alternating voltage VN by the signal generator 1.
  • the signal generator 1 comprises a switch S and a button T.
  • the switch S When the switch S is actuated, the signal generator 1 is separated from the mains AC voltage VN, so that there is no supply voltage Vmains on the output side.
  • the button T is responsible for manipulating the mains voltage VN. If this button T is not pressed, the supply voltage Vmains corresponds to the mains voltage VN. In contrast, the shape of the supply voltage Vmains is changed as long as the button T is pressed.
  • buttons can also be provided, so that several different forms of the supply voltage Vmains can also be generated.
  • the mains voltage is manipulated in accordance with a specific protocol which specifies which information to be transmitted is to be transmitted by means of which voltage curve.
  • the arrow 9 indicates that and how the supply voltage Vmains, for example in the form of alternating voltage half-waves, is passed on to an operating device 6 located in the LED lamp L.
  • the operating device 6 generates a DC voltage, which - as indicated by the arrow 10 - is supplied to an LED module 7 on which the LEDs 8 emitting the light sit.
  • FIG Fig. 2 the problems in determining information impressed by the supply voltage are explained.
  • information is impressed on the supply signal by using phase gates or phase segments.
  • other options such as temporary rectification of the supply voltage, are also permitted and can also be evaluated particularly safely and easily with the aid of the invention.
  • the supply voltage Vmains is composed of positive and negative half-waves, which are labeled "lpar” and “npar” in the diagram. These half-waves are positive in relation to the internal ground potential of the control gear. It can be seen that the half-waves labeled "lpar” are each distorted as they rise from 0 volts. Such deformations in the signal curve arise, for example, from parasitic capacitances and are therefore unavoidable in practice. If the further evaluation were based on a common mode signal, as is the case in the Fig.
  • the Fig. 2 uses a 220 volt AC voltage, as is standard in Europe, for example.
  • FIG. 3 An operating device 6 according to the invention is now shown in a greatly simplified illustration.
  • the operating device 6 is supplied with a supply voltage Vmains, as shown by the arrow 9.
  • an LED module 7 is supplied with an LED lamp 8 with electrical power via the operating device 6.
  • at least one further LED module 7 ′ can also be provided, the structure of which is either the same as the LED module 7 or different from the LED module 7. So that the LED modules 7, 7 'can be operated on the supply voltage Vmains, rectification of this AC voltage is necessary.
  • the supply voltage Vmains is supplied to an AC / DC converter 11 and the rectified AC voltage is then passed on to a DC / DC converter 12.
  • the DC / DC converter 12 is controlled by a control unit 15, which specifies parameters whose implementation by the DC / DC converter 12 enables, for example, dimming.
  • the basic procedure for dimmer or for changing a color value of the emitted light of the LED module 7 does not differ from systems known per se, in which information about this is transmitted to the operating device 6 via separate control lines.
  • the information is not transmitted via separate control lines, but rather is impressed on the supply voltage by manipulating the temporal voltage curve and then extracted again from the supply voltage in the operating device 6. From this, a control command is generated by the control unit 15 and, as indicated by the arrow 16, fed to the DC / DC converter 12 for implementation.
  • detection means 13 are now provided, with which a first voltage and a second voltage are determined separately from one another.
  • the first voltage is the voltage of the first connection of the operating device 6, ie the L-conductor, compared to the ground potential of the operating device 6.
  • the second voltage is accordingly the voltage of the second connection of the operating device 6, ie the N-conductor, compared to the ground potential of the control gear 6.
  • Measurement signals are generated from the voltages in the manner described below. These measurement signals, referred to as mains1 or mains2, then become the evaluation unit 14 supplied, in which the measurement signals mains1 and mains2 are further processed. Through the further processing of the measurement signals in the evaluation unit 14, a signal curve which is characteristic of the originally impressed information is generated and is evaluated in the control unit 15.
  • the control unit 15 determines the control command on which this signal is based and generates a control signal for controlling the DC / DC converter 12.
