Definitions

  • the invention generally relates to the field of interfaces for transmitting communication signals for operating devices of building technology, in particular for lighting (gas discharge lamps, halogen, LED, OLED, ).
  • the invention relates to a communication interface for operating devices for lighting means having two communication terminals.
  • an interface for lighting means has a reception branch for incoming signals, for example from a bus, and optionally also a transmission branch.
  • the interface can be designed to receive digital and/or analog signals.
  • the signals may have amplitudes in the low-voltage range (for example below 15 volts) and/or mains voltage range (220 V to 250 volts).
  • the incoming signals can be DC or AC signals.
  • WO 2006/010416 a bidirectional interface is known, via which an operating device for a lighting means can exchange digital data via a bus with a control center.
  • the interface consists of a receiving channel with subsequent potential separation element and a transmission channel.
  • the reception branch and the transmission channel are combined at the ports intended for connection to the bus. This allows the receive channel to read the data given by the transmit channel onto the bus, which is also desirable. Namely, the receiving channel should check the data output from the transmitting channel and - if time errors are detected - correct.
  • the function poweredDALI was used for the first time. This means that the LED power supplies its own DALI power. Due to the use of the function poweredDALI it was not possible to combine communication standards using a selectively applied (rectified) mains voltage with DALI, since DALI should be isolated and the mains voltage based approaches need a ground GND potential.
  • phase of a simple, standard mains voltage sensor with control input DA/L and the neutral conductor with DA/N may be connected at the interface.
  • the invention relate to a communication interface for lighting means, comprising two communication terminals:
  • the communication interface comprises a DALI-Power-Supply-circuit.
  • the communication interface comprises a diode configured to interrupt a current flow between the first terminal and the second terminal.
  • the communication interface comprises an evaluation circuitry for the mains voltage cycles signal, wherein the evaluation circuitry comprises a rectifier in order to generate a rectified mains signal.
  • the evaluation circuitry is connected to the first or to the second terminal.
  • the evaluation circuitry is configured to detect the number of the cycles of the rectified mains signal.
  • the communication interface comprises a jumper, wherein the jumper selectively connects one of the communication terminals to the ground.
  • the communication interface further comprises a switch for dimming connected to the jumper.
  • the digital signal is a DALI signal.
  • the invention relates to an LED driver comprising a communication interface according to the first aspect or any one of the implementation forms thereof.
  • the LED driver is dimmable with the mains voltage cycles or digital signal, respectively.
  • the invention relates to a method for a communication interface for lighting means, wherein the communication interface comprises two communication terminals, the method comprising the steps of: supplying a first communication terminal with mains voltage cycles signal; and supplying a second terminal with a digital signal, wherein in order to set the communication interface in a state for processing the mains voltage cycles signal, the first terminal is selectively connected to ground, and in order to set the communication interface in a state for processing the mains voltage cycles signal, the first terminal is not connected to ground.
  • LED luminaire shall mean a luminaire with a light source comprising one or more LEDs. LEDs are well-known in the art, and therefore, will only briefly be discussed to provide a complete description of the invention.
  • the aspect of the present invention might contain integrated circuits that are readily manufacturable using conventional semiconductor technologies, such as complementary metal-oxide semiconductor technology, short "CMOS".
  • CMOS complementary metal-oxide semiconductor technology
  • the aspects of the present invention may be implemented with other manufacturing processes for making optical as well as electrical devices.
  • Fig. 1 shows a schematic diagram of communication interface 100 for lighting means 102 according to an embodiment of the invention.
  • the communication interface 100 for lighting means 102 comprises two communication terminals 100a and 100b.
  • the first communication terminal 100a is designed for being supplied with a mains voltage cycles signal, while the second terminal 100b is designed for being supplied with a digital signal.
  • the first terminal 100a In order to set the communication interface 100 in a state for processing the mains voltage cycles signal, the first terminal 100a is selectively connected to ground, and in order to set the communication interface 100 in a state for processing the mains voltage cycles signal, the first terminal 100a is not connected to ground.
  • Fig. 2 shows a schematic diagram of a circuit 200 of the communication interface 100 for lighting means 102 according to an embodiment of the invention.
  • the circuit 200 is composed of three different circuitry components: a DALI circuit 204, a switchDIM circuit 202, and a jumper 206;
  • the DALI bus connects to connections X1-b and X1-c.
  • a microcontroller can be connected to the signals DALI_IN_OPTO and DALI_OUT_OPTO.
  • the upper part of the DALI circuit 204 contains the transmission part of the DALI. It is created around the resistors R142, R145, R148 and R149, the transistors Q140, Q141 and Q145, the capacitors C146 and C148, and the optocoupler U141.
  • the lower part of the DALI circuit 204 contains the reception path of the DALI. It is created around the optocoupler U140, the capacitors C142, C140, C144, the resistors R143, R147, the transistor Q142 and the Zener diode Z140.
  • the optocoupler U140 can signal the level of the DALI bus to the microcontroller via DALI_OUT_Opto.
  • the current source can limit the maximal current load the circuit creates when not in transmission mode.
  • the Zener diode Z140 and the bridge rectifier D140 can drop the received bus voltage to a level to guarantee that a low level voltage does not drive the optocoupler U141, U140.
  • an isolation is created between the microcontroller side and the DALI bus.
  • the isolation is sufficient for evaluation of the DALI software track when the microcontroller is connected in a non-isolated way to the mains supply.
  • a jumper 206 and a mains control voltage circuit 202 can be connected.
  • the jumper 206 selectively connects a terminal of the two communication terminals to the ground of the communication interface 100.
  • the mains control voltage circuit 202 Since the mains control voltage circuit 202 is used in very rare applications, it can be set on the same pin via the jumper 206. That is, in order to use the mains control voltage circuit 202, the jumper 206 has to be place on the circuit 200.
  • a DALI power supply circuit 300 may be deactivated and it may be deactivated if the jumper 206 is placed on the circuit 200.
  • This option could be used if there is no space for a separate pin for mains control voltage circuit 202.
  • the device automatically detects the connected signal and automatically switches to the correct operating mode. Even a connected sensor on the smart interface is detected automatically.
  • the two communication terminals 100a and 100b can be connected to a common reception branch in the communication interface 100 for a digital signal. Furthermore, an evaluation circuit for the looped mains voltage may be connected to one of the two terminals 100a, 100b. For example, this evaluation circuit can detect the number of looped through power waves.
  • the evaluation circuit for the loop-through mains voltage supply can comprise a rectifier (diode circuit), so that the switch dimming signal is then a rectified AC signal for further evaluation and the number of cycles can be detected on the software side.
  • a terminal can be saved, which otherwise would have to be provided by passing out of the device of the terminal X1-a in the mains control voltage circuit 202.
  • the above illustrated embodiments are functional for a DALI interface without the DALI power supply 300.
  • a diode D161 can be provided, which can be designed to be 230 V in a voltage-proof manner in order to prevent a current flow between the two terminals 100a, 100b.
  • Fig. 4 shows a schematic diagram of a method 400 for a communication interface 100 for lighting means 102, wherein the communication interface 100 comprises two communication terminals 100a and 100b, according to an embodiment of the invention.
  • the method 400 comprises the steps of:
