Definitions

  • the present invention relates to an LED module and an electronic ballast that is set up to operate the LED module, and a lamp that has these components.
  • the requirements for the lighting task can change over the course of the service life of a light, especially an outdoor light, such as technical street and tunnel lights or parking lights.
  • Changeable road layouts, peripheral buildings or additional pedestrian or cycle paths can change the requirements for an already installed luminaire in such a way that there is a need to integrate additional functions into the luminaire.
  • Luminaires with Zhaga or Nema sensor interfaces and electronic ballasts according to the D4i standard are known in the prior art, which can be adapted to a certain extent to changing requirements for the lighting task if corresponding additional components, eg a corresponding sensor system, are retrofitted.
  • additional components eg a corresponding sensor system
  • An electronic device can be mechanically and electrically connected to the light via a Zhaga/Nema socket.
  • the light provides a standardized power supply according to DIN EN 62386 Part 150 (AUX power supply) to operate the additional electronic device (described in DIN EN 62386 Part 351).
  • the D4i light has a communication interface according to DIN EN 62386 (corresponding to DALI-2) with the D4i-specific extensions Part 250 (Integrated bus power supply), Part 251 (Memory bank 1 extension), Part 252 (Energy reporting) and 253 (Diagnostic maintenance).
  • the communication protocol provided therein enables a large number of specified lamp operating parameters to be read out, in addition to the familiar DALI-2 control functions.
  • single-channel drivers are used without communication between the driver and the LED module, the possibilities for functional expansion are severely limited.
  • EP 2 676 527 B1 System Another improvement is the in EP 2 676 527 B1 System.
  • data relating to the parameterization of the light are stored in a module memory of the LED module and in an operating memory of the ballast. If the LED module or the operating device is replaced, the data can be transmitted to the new device in each case in order to receive the parameterization of the luminaire. As a result, the lighting task can be performed exactly again without the need for manual parameterization of the luminaire when replacing a component.
  • Object of the present invention is an LED module for a lamp and an electronic ballast and a Provide light that allow an adjustment of the light to new lighting tasks can be done without having to make a complete replacement of the light.
  • the object is achieved by an LED module according to claim 1 and by an electronic ballast according to claim 8 and a luminaire according to claim 10.
  • the LED module of the present invention includes an array of LEDs connected to a line interface in the LED module to supply electrical power from an electronic ballast to the LED array.
  • LEDs Light Emitting Diodes
  • a special feature of the embodiment of the LED module according to the invention is a data bus interface, which enables the electronic ballast and the LED to communicate with one another in order to forward the range of functions of the LED module to the electronic ballast.
  • the range of functions has one or more of the following functional features that are available in the LED module: changeable light color, changeable light distribution, and/or changeable dimming level. This allows, for example, the lighting task to be adapted to a changed road layout or to a peripheral development.
  • the range of functions also includes that the LED module provides measured values from one or more sensors that are integrated in the LED module or are connected to the LED module, wherein the sensors can include the following types in particular: environmental sensors, eg: for temperature, brightness of ambient light of the lamp or humidity, and/or traffic flow sensors, eg IR sensors for detecting people or vehicles, or speed sensors for measuring vehicle speeds.
  • Luminaires are often initially installed without sensor technology and it is only later that the need to use the luminaires as sensors is recognized, for example to change the light output of the luminaire according to the measured values. In the prior art, it has required such a retrofitting with sensor technology, including that To change control of the LED module by the electronic ballast.
  • the range of functions further includes a function of the LED module for projecting symbols or text information through the LED group in the LED module, for generating an acoustic signal via an LED module integrated in or with the LED module connected speakers and/or to transmit messages via a wireless interface, e.g. via a mobile network or via WLAN.
  • a wireless interface e.g. via a mobile network or via WLAN.
  • the LED module also includes a memory for storing configurations of the LED module, the data interface being set up to transmit information from the memory to a connected LED module.
  • the LED module according to the invention is backwards compatible with the LED modules from the prior art, for example in the EP 2 676 527 B1 are described.
  • the data bus interface is set up to receive a firmware update in order to update firmware for the LED module To update.
  • the LED module is upgraded without having to replace the LED module.
  • the luminaire can receive a corresponding upgrade of the firmware from a system outside the luminaire via the electronic ballast and transfer it to the LED module for installation via the data bus interface.
  • the power interface is arranged to be connected to a single-channel driver in the TOE in order to receive the electrical power of the TOE via only one channel at the power interface.
  • a frequent problem when expanding the range of functions of an existing luminaire is that the LED module cannot be replaced with a new module with a more complex range of functions, e.g. with changeable light colors or changeable light distribution, because an electronic ballast is required to operate the new LED module with multiple channels is required. In many existing lights, however, only one electronic ballast with one channel is installed. Since in the system according to the invention the new range of functions can be integrated into the luminaire solely through the LED module, it is possible in these embodiments to continue to operate the new LED module with a single-channel ballast.
  • the data bus interface is set up to receive control data for operating the LED module within the scope of the available range of functions of the LED module, wherein the control data can relate in particular to one or more of the following functions of the LED module: changeable dimming level related to a maximum luminous flux of the LED group in the LED module, changeable fading time, in particular encoded according to a DALI sequence scheme; changeable light colour, in particular color temperature, for example between 1,000 K and 10,000 K; selectable light distribution from a selection of predefined light distributions; and timing of light scenes including a dimming level, a light distribution and/or a light color.
  • the electronic ballast can fully support the expansion of the range of functions of the LED module.
  • an electronic ballast which has a data bus interface which is set up to communicate with an LED module as described above.
  • a further aspect of the invention relates to a lamp which has an LED module as described above and an electronic ballast as described above.
  • figure 1 shows a schematic structure of a lamp according to an embodiment of the present invention.
  • Embodiments of the present invention can be implemented in various types of luminaires.
  • Luminaires for outdoor use are preferred, in particular street luminaires, because with this type of luminaire the requirement often arises that the lighting task of the luminaire has to be adapted to changed environmental conditions, e.g.
  • the lamp is designed as a street lamp and includes a lamp housing 3 which is placed on a lamp post 5 .
  • An LED module 4 is integrated in the lamp housing 3 and has the lighting means in the form of a group of LEDs (not shown in the figure).
  • an electronic ballast 1 which is primarily intended to provide the electrical power for the LED module 4 .
  • the LED module 4 has a power interface (not shown in the figure), which is connected to a power output interface of the electronic ballast 1 .
  • the electronic ballast 1 and the LED module 1 exchange information via the data bus, in particular information relating to the range of functions that the LED module 4 provides.
  • the electronic ballast 1 is thus able to recognize all functionalities of the LED module 4 and, if required, to make them available to a higher-level system outside of the light.
  • the LED module 4 thus becomes the functional component of the light and therefore differs from common light concepts in which the LED module 4 brings variant-dependent properties such as light distribution, luminous flux and light color into the system, but does not bring its own functions into the system.
  • the LED module 4 functions such as changeable light color, changeable light distribution, sensors for example environmental and or traffic flow, wireless interfaces or Add functions that are not yet known to an existing luminaire without having to replace electronic ballast 1.
  • lamp functions were only brought into the lamp via new electronic ballasts 1 (e.g. DALI, D4i), it is now possible to expand the range of functions of the lamp or adapt it to new conditions by replacing the LED module 4.
  • the system is also designed to be both upwards and downwards compatible, which means that lights in an existing system are given functions by replacing the LED module that were not yet available on the market at the time the light was commissioned.
  • the system consisting of ECG 1 and LED module 4 is backwards compatible with the in EP 2 676 527 B1 described system and in turn offers the functional integrity of the lighting system in the event of replacement (LED module or electronic ballast) without requiring intervention in the firmware and parameterization.
  • the in EP 2 676 527 B1 described system is characterized by the fact that the intelligence of the system is in the form of firmware in the electronic ballast 1 and the LED module 4 only has a memory that contains the technical data for the description of the LED module 4 and is used to back up all data, which the system needs after a failure and replacement of the electronic ballast 1 in order to enable functional maintenance including all settings (parameterization), the present invention relies on distributed intelligence in the LED module 4 and electronic ballast 1.
  • the LED module 4 thus becomes an independent functional unit with functions such as tunable white or RGB. While prior art fixtures require a multi-channel driver to drive an RGB or TW module, the embodiment of the invention can still use a single-channel driver without any intervention in the firmware of the electronic ballast 1 can communicate directly with an RGB module, for example.
