Definitions

  • the invention relates to an arrangement for controlling LEDs, which can be used to illuminate the floor, ceiling and / or wall panels and tiles in sections, the panels having pattern cutouts that can be illuminated.
  • Such a system for the section-wise illuminating of rectangular or square panels or tiles laid in a composite and having illuminable pattern sections is from the DE 20 2020 000 827 U1 of the applicant known.
  • LEDs are supplied with energy via a power supply unit; if colored light is used, a controller is required, 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, since here a data signal is required which is provided by special controllers in the form of digital multiplex or serial peripheral interface signals.
  • the control of the LEDs and thus the power supply takes place exclusively with a voltage of 5 V, since the chips inside the LEDs would otherwise be damaged.
  • the data signal is a square wave voltage and not 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 light module with a module carrier on which a light source with the LEDs connected to a circuit board and an autonomous module electronics that control the LEDs. Control of 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 strings 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 strings at a voltage, which comprises a first LED string and at least one second LED string, each of which has a number of cascaded LEDs, the first and second LED strings in parallel are connected to each other between a common input node and a common reference node to which the voltage is applied.
  • a voltage which comprises a first LED string and at least one second LED string, each of which has a number of cascaded LEDs, the first and second LED strings in parallel are connected to each other between a common input node and a common reference node to which the voltage is applied.
  • the method comprises generating a modulated optical signal and transmitting the modulated optical signal between the LED module and converter.
  • the LED module comprises a module communication device for communication with the LED converter using the modulated optical signal, while the LED converter comprises a converter communication device for communication 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 lamp.
  • the LED driver (light emitting diode driver) is configured to control (energize) an LED light source and a lighting system with LED light sources.
  • control arrangement for fault-tolerant and electromagnetically compatible control of a large number of execution units.
  • the control arrangement advantageously allows execution units, which are segmented into a plurality of serial partial chains, to be controlled in such a way that both a high level of so-called common-mode stability and a high level of reliability even with a large number of execution units are achieved.
  • the object of the invention is to provide an arrangement for controlling digital LEDs with an integrated circuit, which are arranged in sample sections of floor, ceiling and / or wall panels, which is fault-tolerant in the broadest sense and largely through little technical effort is marked.
  • the fault tolerance is based on electromagnetic compatibility and seizure safety.
  • the ranges 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 by external induction.
  • an arrangement for driving LEDs which are used for the section-wise lighting of pattern cutouts embedded in floor, ceiling and / or wall panels and tiles, as in FIG DE 20 2020 000 827 U1 described by the applicant, with a power supply, an LED controller and at least one converter, which is each connected to PCB tapes or LED strips.
  • the arrangement according to the invention comprises an LED controller that generates an SPI signal and converts it into an optical signal, and at least one LED converter by converting the optical signal back into an SPI signal and for controlling the LEDs in the PCB - forwards ribbons or LED strips.
  • the LED controller is connected to a power supply, for example a protective 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 comprises a main board with a processor and processing of setpoint information that is sent to the LED controller by an app via Bluetooth or W-LAN. Settings for the light properties are made in the app and the resulting setpoints are created.
  • the main board of the LED controller uses the transmitted setpoint information to generate and output a time-critical SPI signal. This takes place 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 z. 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, no second data line is required
  • the output time-critical SPI signal is converted into an optical signal via a modulator and passed on to the downstream LED converter via 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 by means of a voltage converter and output via contact lines to the LEDs on the PCB strips or LED strips.
  • the modulated optical signal is converted into an SPI signal in a demodulator and this signal is fed to the integrated circuits of the LEDs via a signal line (SPI).
  • SPI signal coming from the LEDs is fed to a modulator which converts the SPI signal into an optical signal and feeds this 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 to the evaluation circuit arranged in the LED converter 2 via the BMA signal line.
  • BMA fire alarm system
  • the SPI signal output by the demodulator to the evaluation circuit is switched off and, after an alarm program has been run in the evaluation circuit, a new SPI signal is output to the LEDs on the PCD strips or LED strips.
  • the LEDs can be operated, for example, as running lights to mark the escape direction of the escape routes.
  • the LED converters can be equipped with additional functions, which consist in switching to battery operation in the event of a power failure.
  • the LED converters have an accumulator charge control and the option of connecting at least one accumulator to the LED converter via a plug contact.
  • the Figure 1 shows the structure of the arrangement for controlling LEDs 3 in PCB strips or LED strips 5.
  • the arrangement comprises a DC voltage source 6 which is connected to the LED controller 1 and three downstream LED converters 2 via the lines.
  • 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 strips 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 in floor, ceiling and / or wall panels and tiles and in the end strips.
  • the Figure 2 shows the structure of the LED controller 1 including the connecting lines DC voltage supply minus pole 100, DC voltage supply plus pole 101 coming from the voltage source 6 , a motherboard 7 with processor for receiving signals from an APP via Bluetooth or W-Lan, a modulator 8 for Conversion of an SPI signal into an optical signal.
  • the output of the main board 7 is connected via the signal line SPI 112 to the input of the modulator 8 , the output of which is connected to the optical signal conductor 4 .
  • the LED controller 1 is connected to a protective extra- low voltage source 6 (max. 75 volts direct current) and also conducts this through.
  • the main board 7 can receive data via radio and contains the program for controlling the LED technology.
  • the board outputs an SPI signal. This SPI signal is converted by the modulator 8 into an optical signal and output.
  • the Figure 3 shows the structure of an LED converter 2 comprising the DC voltage supply minus pole 100, DC voltage supply plus pole 101, the optical signal conductor 4, a demodulator 9, a voltage converter 10 and a modulator 8.
  • the demodulator 9 converts this via the optical signal line 4 from LED controller 1 converts incoming optical signal into an SPI signal and feeds this to the LEDs 3 via the signal line 112 .
  • the LED converter 2 receives the supply voltage (eg 48 volts) and an optical signal from the LED controller 1.
  • the supply voltage 5 is converted into 5 volts by means of a voltage converter 10 and for the LED strip 5 via the contacts 110 and 111 issued.
  • the optical signal is converted back into an SPI signal by means of the demodulator 9 and is also provided via the signal line 112 for connecting an LED strip 5 .
  • the data output of the LED strip 5 is converted back into an optical signal by means of the modulator 8 and made available for the connection of a further converter.
  • the Figure 4 shows another embodiment of an LED converter 2.
  • This also includes an evaluation circuit that is connected to a fire alarm system or its system.
  • This LED converter 2 fulfills the same functions as the one in Figure 3 described LED converter 2, but with an extended function.
  • the evaluation circuit 11 which is connected to the fire alarm system via the signal line 120, evaluates the signals coming from the fire alarm system using a program loaded onto the processor of the evaluation circuit 11.
  • the SPI signal is switched off by the demodulator 9 and an alarm program is played and the SPI signal to the LEDs 3 can then be operated, for example, as running lights to mark escape routes.
