Definitions

  • the invention relates to a supply unit for LED units and a method for recognizing the identity of LED units, in particular for recognizing of parameters necessary for the power supply of the LED unit, and a corresponding LED unit.
  • supply units work of LED units with different loads.
  • the term LED light emitting device
  • OLEDs organic light emitting device.
  • supply units only supply an output voltage to supply power to a connected LED unit. Should several or different LED units supply power experience the supply unit, so the supply unit for the power supply be designed by several or different LED units and the information required for the power supply about nominal parameters of the power supply Get LED units.
  • the object of the present invention is therefore a supply unit LED unit and a method of recognizing LED units that create with regard to the supply of various LED units by one supply unit is improved.
  • a supply unit for at least an LED unit has a detection unit, which are designed to recognize the identity of the LED unit via electrical quantities is, as well as supply connections for the power supply of the LED unit the supply unit.
  • the identity is recognized the LED unit via the supply connections.
  • the supply connections can serve the power supply, at the same time be used to connect the identity Recognize LED units and determine which ones, for example Power supply for the LEDs is necessary. This makes the supply unit more compact and be kept simple, so that the required installation effort is significantly reduced.
  • control unit in the supply unit included based on the recognized identity of the LED unit controls the power supply of the LED unit.
  • This enables evaluate the recognized identity of the connected LED units and accordingly control, so that the supply unit automatically always the right one Provides power supply when, for example, a new or additional one LED unit with possibly different nominal load connected to the supply unit becomes.
  • the control unit can also supply power prevent and feedback on the status of the connected Output the LED unit if it is defective, for example, or with the supply unit is not compatible.
  • the detection and the power supply take place preferably exclusively via two supply connections.
  • the LED unit has the following steps: providing a first electrical variable for the LED unit to be recognized, recognizing the identity of the LED unit based on one provided by the LED unit in response to the first electrical quantity second electrical quantity. Identity is recognized via supply connections for the power supply of the LED unit.
  • the method further comprises controlling the Power supply to the LED unit based on the recognized identity of the LED unit. This means that not only the identity of a connected LED unit can be recognized, but the information about the identified identity can processed and the power supply controlled accordingly.
  • the method can additionally be carried out repeatedly when the LED unit is in operation become.
  • the necessary power supply checked and adjusted if necessary.
  • the LED unit is recognized and supplied with power exclusively via two supply connections.
  • a voltage which is small in relation to the power supply is preferably applied as the first electrical variable, and the LED unit is recognized as a second electrical variable by an impedance of an identification unit.
  • the impedance of the identification unit is small compared to the LED impedance effective when the small voltage is applied. The consequence of this is that the supply unit essentially only " sees” the identification unit from the LED unit and only evaluates the second electrical variable provided by the identification unit, without the influence of downstream LEDs significantly influencing the returned second electrical variable.
  • the impedance can be an ohmic resistance.
  • active components are also possible that generate an electrical quantity by themselves. Digital components can also be used for the purpose mentioned.
  • the identification unit is preferably a component which is separate from the LEDs and which can be connected upstream of the LEDs in the LED unit, for example.
  • the LED unit according to the invention for connection to the above-mentioned supply unit has at least one LED, supply connections for power supply the supply unit, and an identification unit with the detection the technical properties of the identity of the LED unit.
  • the identification unit can be identified via the supply connections.
  • the detection and power supply can preferably be carried out exclusively via two supply connections are made via which the LED unit with the supply unit is connected.
  • the identification unit can be switched off. This is an advantage as it is used in the actual power supply is not required and thus unnecessary power consumption is avoided.
  • the impedance of the identification unit is preferred compared to the one in relation to the power supply applied to the LED unit small voltage effective led impedance small.
  • the figure shows a system consisting of a supply unit 1 and an LED unit 2, which are connected to one another via the supply lines 4a, 4b.
  • optional 2 additional connections 8 can be connected to the LED unit for connecting further LED units 2 are provided, which are then also provided by the supply unit 1 can receive the required power supply.
  • the supply unit 1 contains a recognition unit 7, by means of which the supply unit 1 can recognize information about the connected LED units 2, for example the supply voltage or the like required for the power supply by the supply unit 1 for operating the LED unit 2.
  • an identification unit 3 is provided in the LED unit 2 according to the invention in addition to the LEDs 9.
  • the identification unit 3 returns information about the identity of the corresponding LED unit 2 to the recognition unit 7 in the supply unit 1. This is done in that the detection unit 7 first outputs an electrical quantity (generally a small voltage compared to the supply voltage for the connected LEDs) to the LED unit 2 via the supply lines 4a, 4b (position A of the switch 13).
  • the identification unit 3 can only consist of an impedance, an ohmic resistance, which is characteristic of the LED unit.
  • This impedance is preferably small compared to the effective impedance of the LEDs 9 at a low voltage, so that, for example, when a voltage is applied, a current only flows through the identification unit 3 and the detection unit 7 therefore does not “ see” the LEDs 9 and thus exclusively receives feedback from the Identification unit 3 to the recognition unit 7.
  • the detection unit 7 detects a small voltage in the supply unit 1 applied to the LED unit 2 (switch position A), then flows in Current through the identification unit 3, in particular the resistor 11, via the Connections 4a, 4b back to the detection unit 7 and is measured there, and the Resistance 11 in the identification unit 3 can be determined in this way.
  • the identification unit can also resist other electrical or electronic ones Contain (also active) components that are suitable for a for the identification unit 3 of the corresponding LED unit 2 characteristic signal in Responding to one of the recognition unit 7 via the supply connections 4a, 4b output electrical quantity provided.
  • the recognition unit 7 can now be the one for the connected one LED unit 2 required power supply (supply voltage) determine.
  • the information about the power supply can be supplied via an optional control unit 6 subsequent to one provided in the supply unit 1
  • Output unit 5 are forwarded, for example, the necessary supply voltage generated and output for the LED unit (s) 2.
  • the control unit switches 6 in the switch state B, and that generated by the output unit 5 Power is supplied to the LED unit (s) 2 via the supply connections 4a, 4b.
  • the identification unit 3 also represents a power consumer, it can optionally switched off via a switch 12 triggered by a control element 10 when the power supply begins. For example happen that the control element 10 one of the supply unit 1 recognized supply voltage and then detects the switch 12 in the open state switches so that a supply current only through the LEDs 9 flows.
  • switch position A While the power supply is in the detection mode (switch position A) are switched over, for example to check whether an LED unit 2 is defective or has been replaced. As a result, the supply parameters during the Operation redefined and in output mode (switch position 2) accordingly be adjusted.
  • the structure according to the invention can both supply the LED units 2 as well as identity recognition, d. H. the supply parameters, of the LED units 2 take place exclusively via the supply connections 4a and 4b. Additional lines or connections are not necessary, so use complicated and complex circuits for LED supply is avoided.
