Definitions
- the invention generally relates to a system for an elongated light band or for a light line luminaire according to the preamble of claim 1 and a functional module, in particular for such a system, according to the preamble of claim 7.
- the invention relates in particular to a light band system or a light band that is equipped with a data line and a functional module for data transmission for a light band system.
- Lighting devices for large areas are often implemented in the form of light strip systems.
- a plurality of elongated lights are typically provided, mostly in the form of a continuous band of elongated modules, typically in several parallel rows next to one another, corresponding to the desired room lighting.
- such light strips are typically suspended from the ceiling of the room or mounted directly on the ceiling.
- light line systems enable a high degree of flexibility in the arrangement and selection of the lamps and components used, so that a wide variety of lighting tasks can be implemented according to customer requirements.
- modular continuous-row systems can also be relatively easily adapted later to changed requirements, e.g. if the room is used differently.
- light strips offer further advantages, for example in terms of safety and cost-effectiveness.
- a typical light line system comprises at least one light line luminaire, usually with a number of elongated support profiles for attaching light modules to the support profiles.
- the support profile also called carrier profile
- the support profiles can be designed as support rails and are usually offered in different lengths, usually with a profile cross section that remains the same throughout the system.
- the desired modules or modules selected from the modular system, in particular light modules, are attached to the support profiles.
- Light modules with LED light sources, for example, are common today.
- the multi-wire supply is typically a multi-phase supply with at least three phase conductors for load balancing, the neutral conductor and the protective earth conductor. If necessary, additional conductors, e.g. for the emergency power supply and/or lines for lighting control, e.g. according to the DALI protocol, can be provided in the support profile.
- WO 2021/043921 A1 a light line system with a data transmission function was proposed, which primarily transmits data between components of the light line system, but can also provide a WLAN access point, for example.
- this system has a data connection for receiving data and an adapter connected thereto, which is designed to transmit the data to a second adapter using a modulation method via electrical conductors of the supply.
- WO 2021/043921 A1 proposes the use of a powerline adapter (also called PLC—Powerline Communications), which modulates data onto existing power lines and demodulates them again. In this system, the electrical supply itself is used for data transmission.
- PLC Powerline Communications
- a function module for WLAN data transmission is known from patent EP 2512209 B1.
- this is suitable for mounting on a light strip and can provide a WLAN access point as an adapter and for this purpose be integrated into an existing LAN network, for example.
- a first object of the present invention is therefore to provide an alternative, sustainable solution for data transmission in to propose a light line system, which allows to keep the installation effort low, but enables reliable and robust information technology (IT).
- This object is achieved by a system according to claim 1 or, independently thereof, also by a function module according to claim 7.
- a future-proof, IT-capable or IoT-capable light line system should be proposed.
- the system should provide high or sustainable data transmission capacity, be able to be implemented comparatively inexpensively and/or be comparatively easy to install.
- the proposed solution should preferably also enable existing light strips to be retrofitted with sustainable data transmission technology.
- the main feature according to which at least one optical fiber optic cable (LWL) is used as the data line, contributes to the solution of the first-mentioned object.
- a POF (polymeric optical fiber) optical fiber can be used as the optical fiber optic cable.
- the abbreviation POF here means a plastic fiber optic cable for data transmission, i.e. a data line with an optical fiber core comprising or consisting of plastic or a so-called "polymer optical fiber” (also Engl, "plastic optical fiber”).
- the POF fiber-optic cable can be designed in accordance with IEC 60793-2-40, e.g. type IEC 60793-2-40 subclass A4a.2.
- a large core POF line is particularly preferred, with a typical core diameter of approx. 980 ⁇ m to 1000 ⁇ m or 1 mm core diameter of the optical fiber.
- the data line can in particular comprise at least one pair of conductors made from two polymer optical fibers as an optical waveguide, in particular as a duplex POF data line or in particular for duplex data transmission. If necessary, several pairs of conductors made of optical waveguides can be provided, depending on requirements. Instead of a pair of fibers with one fiber each for sending and receiving direction, a single fiber or individual POF fiber-optic cables can be used, on which, for example, the transmission and reception directions are implemented using two different wavelengths, for example using optical wavelength division multiplex technology (wavelength division multiplex, WDM or wavelength division multiple access, WDMA).
- WDM wavelength division multiplex
- WDMA wavelength division multiple access
- At least one active data coupling unit e.g. an active data network device
- at least one data interface for optical data transmission via optical fibers in particular via the POF - LWL or the POF conductor pair
- the data coupling unit can compensate for the attenuation behavior of a POF data line and/or provide flexibility through additional interfaces to other wired or wireless data lines, in particular to any IoT devices in the broadest sense.
- optical waveguides and data coupling units according to ISO/IEC/IEEE 8802, in particular according to ISO/IEC/IEEE 8802-ands3:2017/Amd.9:2018(E) and/or for implementing a data connection in Gigabit ETHERNET technology, are preferred be of the 1000BASE-RHx type, particularly preferably 1000BASE-RHA or possibly also 1000BASE-RHB.
- the system be set up in such a way that it also supplies the required power supply to the active
- Data coupling unit can provide or effect by means of the provided or existing supply in the support profile.
- the invention relates to a light band or light band system with an active optical data network, preferably with POF as the optical waveguide, and the individual system components that are essential for this.
- data coupling units which are designed as active network devices, can be connected by line segments each consisting of at least one optical fiber, in particular POF optical fiber, in particular in line or daisy chain topology.
- the power supply for the active network devices is preferably provided by the light strip itself.
- the system can supply power to the active data coupling unit in particular using a suitable contact device and predetermined conductors of the supply in the support profile or using a supply connection of a component of the continuous-row system that is supplied via the supply.
- the system can thus achieve the power supply of the active data coupling unit directly through the supply inherent in the support profile, in particular through predetermined conductors of this.
- the active data coupling unit preferably has its own power supply unit, in particular a switched-mode power supply unit (also referred to as SMPS).
- SMPS switched-mode power supply unit
- a switched-mode power supply with a DC voltage converter is particularly preferably provided for providing different operating voltages.
- the term electrical supply is understood here to mean a supply device which has at least conductors for the power supply or is used for the power supply.
- the supply can in principle have any design suitable for a light band and is preferably in the Support profile arranged.
- the supply can also include a data line, eg a pair of DALI conductors.
- the system can also indirectly provide or effect the power supply of the active data coupling unit from the supply, in particular via a supply connection intended for this purpose of a component provided in the light strip system, which is intended to be supplied from the supply.
- a supply connection of an operating device for light sources in particular a D4iTM connection according to the DALI-2 specification (cf. https://www.dali-alliance.org/d4i/), can be considered for this.
- the active data coupling unit in such a way that it is supplied by the actual supply connections of an operating device, e.g. with 48 V DC voltage for LED modules.
- An indirect supply can noticeably reduce hardware expenditure for the supply in the active data coupling unit, e.g. operating voltages required for suitable DC-DC converters. A cheaper and more compact data coupling unit can thereby be made possible.
- POF fiber optic cables as a data line offers a number of advantages.
- POF fiber-optic cables are generally not susceptible to electromagnetic interference and, conversely, do not cause any electromagnetic interference in surrounding electrical lines, e.g. for lighting control, or sensitive components, e.g. the LED driver or control gear.
- CAT-7 copper data lines POF data lines have a noticeably smaller cross-section.
- POF fiber optics have a significantly lower length-specific weight than copper data cables. The POF fiber optics can thus be routed more simply, easily and space-savingly at any point of the cross-section, in particular in the mounting rail, or also on the outside of the mounting rail. This is particularly advantageous if several data lines may have to be laid.
- POF fiber optic cables are inexpensive, especially in Compared to fiber optic data lines, they still offer comparatively high bandwidths and data transmission rates.
- POF optics are comparatively easy to handle and can be installed with simple tools without any additional effort during the manufacture or installation of the light strip.
- POF LWL in particular of the ETHERNETE 100OBASE-RHA type, can be processed and installed by fitters using comparatively simple tools and without special knowledge.
- State-of-the-art POF data lines can achieve data rates of lGbps or more over distances of up to 50m.
- the length can also be further increased by means of suitably arranged data coupling units, e.g. Thanks to one or more data coupling units, longer distances with a high data rate are possible, possibly despite connections or couplings with increased attenuation between individual line segments and/or with devices.
- the data line is therefore preferably a non-wired line, in particular not a copper-wired line, specifically in particular an optical waveguide (LWL) and very particularly preferably a POF optical waveguide.
- the proposed data coupling unit can, for example, comprise an active network device, such as a POF switch or the like, or form such or be designed as such.
- the data coupling unit can be installed in the continuous-row system and supplied with power from it with comparatively little effort.
- the data coupling unit can be designed in particular as a communication device for the transmission or exchange of network data or user data.
- the housing design of the data coupling unit is preferably suitable for integration, installation or embedding in a light strip.
- the supply can be designed, for example, as an electrical supply line or through-wiring, busbar, current-conducting profile, or the like.
- the supply is typically multi-wire, i.e. it includes several conductors, in particular conductor wires, at least for the power supply of the light modules of the light strip. If the support profile, e.g. as a conductor rail, is itself used as a protective conductor, the supply always has at least two conductors or wires for the power supply.
- existing multi-wire supplies for example a multi-wire power rail or a multi-wire current conducting profile or the like, can offer an inherently suitable power supply that is available at any desired longitudinal position along a light strip.
- Existing, predetermined conductors can be used for this purpose, which only supply devices of the data network, in particular also the one or more data coupling units, in a dedicated manner in the sense of an IT supply.
- the individual conductors of the supply are preferably wires, in particular copper wires, in particular with a cross section in the range from L0.5 mm 2 to ⁇ 2.5 mm 2 .
- the or each data coupling unit preferably has its own switching power supply, preferably with suitable connection means for connection to selected conductors of the supply of the light strip.
- Switching power supplies have, among other things, a low no-load power loss.
- an electronic SELV switching power supply with a transformer for galvanic isolation of the secondary side from the primary supply is preferably provided.
- the switched-mode power supply is preferably designed as an integrated assembly and part of the data-coupling unit, in particular accommodated in the housing of the data-coupling unit.
- the data coupling unit in particular the switched-mode power supply that may be integrated, is preferably designed specifically in accordance with one or more relevant standards for lighting devices, similar to drivers for lighting devices.
- the data coupling unit, in particular the switched-mode power supply can in particular be generally compliant with EN/IEC 60598-1:2018.9 or DIN EN 60598-1:2018-09 (corresponds to VDE 0711-1).
- the data coupling unit and in particular the switched-mode power supply should have a suitable rated service life, among other things.
- the integrated switching power supply of the data coupling unit preferably conforms to EN/IEC 55015:2019-08 (corresponds to VDE 0875-15-1) and/or EN/IEC 61000-3-2:2014 (corresponds to VDE 0838-2) and/or EN /IEC 61547:2009 (corresponds to VDE 0875-15-2).
- the switched-mode power supply of the data coupling unit can preferably be designed specifically for a lighting application or lighting devices, particularly with regard to radio interference, undesired harmonic currents and/or EMC immunity.
- the switched-mode power supply of the data coupling unit can in particular be designed with means for power factor correction, for example a PFC circuit or PFC stage (English for power factor correction).
- the switched-mode power supply can be multi-stage or single-stage be. It can advantageously include an input-side EMC filter stage.
- the switched-mode power supply includes, in particular, a DC-DC converter, which can preferably be embodied as a flyback converter or flyback converter (also buck-boost converter).
- the switched-mode power supply preferably also provides a 48 V DC supply voltage for a PSE unit, in particular for a PoE unit provided in a preferred embodiment in the data coupling unit.
- Selected components of the switched-mode power supply have a rated service life that is sufficiently dimensioned for lighting equipment, e.g. according to EN/IEC 60598-1:2018.9 or DIN EN 60598-1 (VDE 0711-1):2018-09.
- the housing of the active data coupling unit preferably has a tc point on its outside which is marked in a visually recognizable manner.
- the tc point is placed, for example, directly above components, for example the storage capacitor mentioned above, which are critical for temperature and service life.
- the fiber optic data line itself can be arranged as a separate line, for example independently of the supply on or in the support profile and can also be easily retrofitted if necessary. However, the fiber optic data line can also be attached together with the supply, for example pre-installed in a so-called current conducting profile or else be relocated here later.
- the light strip itself can also be used as a protective or mounting device for the optical fiber optics, so that the material and time required to produce the data infrastructure is reduced overall because, for example, significantly fewer cable ducts or the like are required.
- the spatial position of the light bands also offers advantages, including additional security against mechanical damage, e.g. from mobile equipment in a warehouse.
- antenna positioning for wireless networks e.g. via WLAN, WiFi or promising standards such as WiFi 6 or IEEE standard 802.11ax, light strips mounted or mountable at a suitable height already allow good network coverage of large areas, without additional installation work for antenna positioning.
- the antenna characteristics are basically independent, it is comparatively easy to achieve relatively good radio coverage in a large area from the position of the light band, without any additional effort for mounting and wiring the radio network devices.
- the proposed solution thus offers a cost-effective and yet future-proof option for providing data networks, in particular mixed wireless data networks and fiber-optic data networks, in large areas, both for new installations and for retrofitting.
- Data lines integrated into the light line system allow numerous other advantages, e.g. the integration of control and analysis functions and components, such as sensors for heat mapping, asset tracking, indoor positioning, etc. or sensors and actuators, e.g. for building management in general and specifically for lighting control eg using an Ethernet-to-DALI adapter, or for connecting other IoT components to a data network.
- control and analysis functions and components such as sensors for heat mapping, asset tracking, indoor positioning, etc. or sensors and actuators, e.g. for building management in general and specifically for lighting control eg using an Ethernet-to-DALI adapter, or for connecting other IoT components to a data network.
- the light line system extended with a data line can also be easily and cost-effectively integrated into sustainable IoT or Industry 4.O applications via suitable interfaces and/or provide relevant infrastructure, in particular data network infrastructure, for this at low cost.
- the light line system proposed here is particularly suitable for use as part of an IoT system.
- the fiber optic data line in particular POF data line, can be used here in particular for the transmission of non-system data (user data), e.g. for any IT or IoT application, IIoT application or the like.
