Definitions

  • the invention relates to an arrangement for controlling LEDs, which are used to partially illuminate pattern cutouts embedded in the floor, ceiling and/or wall panels and tiles.
  • Such a system for illuminating sections of rectangular or square panels or tiles laid in a composite, which have pattern cutouts that can be illuminated, is from the DE 20 2020 000 827 U1 known to the applicant.
  • LEDs are supplied with energy via a power supply; if colored light is used, a controller is required, with a pulse width modulating controller and RGB LEDs being used. If running lights are to be used, programmable LEDs are used. This differs significantly from the previous solutions, as a data signal is required here, which is provided by special controllers in the form of digital multiplex or serial peripheral interface signals.
  • the LEDs and thus the power supply are only controlled with a voltage of 5 V, otherwise the chips inside the LEDs would be damaged.
  • the data signal is a square wave voltage and no higher than 5 V.
  • the DE 10 2007 044 567 A1 describes a lighting device with several controllable light-emitting diodes (LEDs) that emit light in different wavelengths.
  • the device contains at least one lighting module with a module carrier on which a light source with the LEDs connected to a circuit board and self-sufficient module electronics that control the LEDs. Controlling digital LEDs with integrated circuits is not possible here.
  • the DE 10 2018 201 365 A1 deals with a circuit arrangement for operating at least two LED strands at one voltage for the purpose of color or color temperature mixing of the light emitted by the LEDs.
  • the starting point is a circuit arrangement for operating at least two LED strands at a voltage that includes a first LED strand and at least a second LED strand, each of which has a number of cascade-connected LEDs, the first and second LED strands being parallel are connected to each other between a common input node and a common reference node to which the voltage is applied.
  • the method includes generating a modulated optical signal and transmitting the modulated optical signal between the LED module and converter.
  • the LED module includes a module communication device for communicating with the LED converter using the modulated optical signal, while the LED converter includes a converter communication device for communicating with the LED module using a modulated optical signal.
  • the DE 10 2016 102 409 A1 includes an LED driver, a lighting system and a light.
  • the LED driver (light-emitting diode driver) is configured to control (energize) an LED light source and a lighting system with LED light sources.
  • the US 2018/295695 A1 relates to an apparatus and associated methods for providing lighting commands for a curtain-shaped decorative lighting system.
  • the curtain configuration of decorative string lights is achieved through the use of string light distribution elements, each of which receives an input signal via a conductive line.
  • the input signal indicates multiple lighting commands.
  • the fairy light distribution element then provides an output signal to a branch connection to which a decorative fairy light can be connected.
  • the output signal provided indicates lighting commands corresponding to a variety of lighting elements distributed along the associated decorative string of lights.
  • the multiple lighting elements of the attached decorative string lights each light in response to one of the lighting commands specified by the output signal.
  • the US 2012/155888 A1 relates to an optical modulator and in particular to a reduced size optical modulator and an optical transmitter containing the same.
  • the optical modulator includes a light input/output unit that receives an incident optical signal that has not been modulated and splits the incident optical signal into a first optical signal and a second optical signal and each splits the first and second optical signals into a first one Path transmits a second path of an optical fiber.
  • the EP 3 118 748 A1 refers to a method for unidirectional data transmission from a safety-critical system to an unsafe system using a data diode.
  • the US 6,292,901 B1 relates to a method for powering a light module, comprising providing a light module, the light module comprising a processor and an LED system, a data signal for the light module, the processor and the LED system of the light module responding to the data signal and withdrawing Power from the data signal to power the light module.
  • the GB 2 501 770 A refers to lighting devices, and in particular to lighting devices that have additional components and circuitry to enable the lighting device to emit light using electrical energy from a secondary power supply (e.g. a battery) when the primary power supply (e.g. B. a battery) is used Mains supply) is interrupted.
  • a secondary power supply e.g. a battery
  • Mains supply Mains supply
  • the object of the invention is to provide an arrangement for controlling LEDs on LED strips or PCB tapes, which are used to partially illuminate pattern cutouts embedded in floor, ceiling and/or wall panels and tiles, comprising a voltage source, an LED Controller and at least two LED converters, each connected to LED strips or PCB tapes, which is fault-tolerant in the broadest sense and is largely characterized by low technical effort and uses a different type of data transmission.
  • the fault tolerance is based on electromagnetic compatibility and seizure safety.
  • the range between the LED controller and the LED converters and thus the LED strips or the PCB tapes should be significantly extended without there being a voltage drop and/or interference, such as external induction.
  • an arrangement for controlling LEDs on LED strips or PCB tapes which are used to illuminate sections of floor, ceiling and/or Pattern cutouts embedded in wall panels and tiles, as in DE 20 2020 000 827 U1 described by the applicant, comprising a voltage source, an LED controller and at least at least two LED converters, each of which is connected to PCB tapes or LED strips.
  • the arrangement according to the invention comprises an LED controller, which generates an SPI signal and converts it into an optical signal, and at least one LED converter, in which the optical signal is converted back into an SPI signal and for controlling the LEDs in the PCB -tapes or LED strips.
  • the LED controller is connected to a power supply, for example a safety extra-low voltage source, which supplies the LED controller with a direct voltage of a maximum of 75 V DC, preferably 48 V DC.
  • the LED controller includes a motherboard with a processor and processing setpoint information that is sent to the LED controller by an app via Bluetooth or WiFi. Settings for the light properties are made in the app and the resulting target values are created.
  • the LED controller motherboard uses the transmitted setpoint information to generate and output a time-critical SPI signal. This happens at exactly the right time intervals (time-critical SPI signal), so that the integrated circuit within the digital LEDs knows what to do. Depending on the number of colors there are e.g. B. for RGB (red, green, blue) a 24 bit combination and for RGBW a 52 bit combination. Since a time-critical SPI signal is generated, a second data line is not required
  • the output time-critical SPI signal is converted into an optical signal via a modulator and forwarded to the downstream LED converter using an optical signal conductor.
  • the LED converter receives the supply voltage (for example 48 V DC) as well as the modulated optical signal.
  • the supply voltage is converted into a low voltage of 5 V DC using a voltage converter and output via contact lines to the LEDs of the PCB tapes or LED strips.
  • the modulated optical signal is converted into an SPI signal in a demodulator and this is transmitted via a Signal line (SPI) feeds the integrated circuits of the LEDs.
  • SPI Signal line
  • the SPI signal coming from the LEDs is fed to a modulator, which converts the SPI signal into an optical signal and feeds it to the subsequent LED converter via an optical signal conductor.
  • another LED converter also includes an evaluation circuit that is coupled to a fire alarm system (BMA). Corresponding signals are sent from the fire alarm system via the BMA signal line to the evaluation circuit arranged in the LED converter 2.
  • BMA fire alarm system
  • the SPI signal output by the demodulator to the evaluation circuit is switched off and, after running through an alarm program in the evaluation circuit, a new SPI signal is output to the LEDs of the PCD tapes or LED strips.
  • the LEDs can be operated as running lights, for example, to indicate the direction of escape on the rescue routes.
  • the LED converters can be equipped with additional functions, which consist of switching to battery operation in the event of a power failure.
  • the LED converters have an accumulator charging control and the option of connecting at least one accumulator to the LED converter via a plug contact.

  • the arrangement includes a DC voltage source 6, which is connected via the lines to the LED controller 1 and three downstream LED converters 2 connected is.
  • the arrangement is not limited to the three following LED converters.
  • the LED converters 2 are each connected to the LEDs 3 of the PCB tapes or LED strips 5 via the signal lines 112.
  • the LEDs 3 are designed as digital LEDs 3 with an integrated circuit.
  • the LEDs 3 are used to illuminate pattern sections that are inserted into floor, ceiling and/or wall panels and tiles as well as in the end strips.
