Definitions

  • the present invention relates to methods for optical signal output of operating parameters in an operating device with an LED light source controlled by the latter, which is formed by at least three LEDs, which are individually intended for the emission of light of different colors and together for the emission of white cumulative light.
  • an LED for emitting light of a color is “determined”, this is to mean that the LED can only produce light of that color.
  • This operating address may differ from an optionally provided by the manufacturer's source address in the device.
  • each bus subscriber will be assigned an operating address, or each bus subscriber has himself assigned an address from the defined address supply.
  • it In order to be able to proceed in a targeted manner in the following actual operation of the lighting system controlled by means of the bus system, it must be learned how the operating address of each connected bus subscriber is. This takes a long time since an operator must physically go to each connected bus subscriber to then typically visually inspect address assignment in place.
  • this installation step is particularly cumbersome if the bus subscribers are widely distributed in a building or possibly over several buildings.
  • so-called emergency lighting devices which, if a mains voltage supply is battery-powered, thus ensure a defined emergency lighting and which are usually distributed particularly widely spaced from each other over buildings. If, therefore, the installer has to move over large areas of the installation area, especially in the case of emergency lighting devices, then at least the in-experience of the assigned addresses should proceed as swiftly as possible.
  • the WO 2006/136236 starts at this point and proposes to provide, in addition to the light source controlled by the operating device, additional optical and / or acoustic signal transmitters which can reproduce the bus address in coded form.
  • additional optical and / or acoustic signal transmitters which can reproduce the bus address in coded form.
  • an acoustic signal generator for example LEDs can be used, which are preferably connected to the operating device.
  • the EP 1 098 550 A2 discloses the possibility of reducing the hardware complexity compared to the prior art described last, in the case of optical indication of the operating time of an operating device. This is achieved by driving the LED light source forming RGB LEDs, which are intended for the emission of monochrome (non-white) light, for the optical signal output of the operating time.
  • the inventive solution additional optical and / or acoustic signal generators are dispensable for the reliable display of the result of a self-test of the operating device.
  • the invention relates to a lighting arrangement according to claim 8.
  • the invention relating to the lighting arrangement has the same object and the same solution principle as the invention relating to the method described above. The corresponding statements are therefore made to avoid repetition.
  • the LEDs selected for signal output should be intended to emit a selected color, but they need not and may also emit a non-monochromatic mixed color. It is essential that the selected LEDs emit a non-white light total light, which differs clearly in terms of its color from the white light that is intended to emit the LED light source intended for the illumination of their environment.
  • the LED light source may consist of three LEDs, one of which is intended to emit red light, a second to emit green light and a third to emit blue light.
  • At least one specific for the emission of monochromatic light LED is controlled so that it transmits information, for example, after the Morse code by short and long illumination.
  • Another variant may be that the LEDs intended for the emission of colored light and forming a subgroup are driven in such a way that they Represent numbers, digits or other symbols, by means of which the signal output is realized.
  • the inventions are suitable for displaying an originating address or an operating address of an operating device for the LED light source or another light source.
  • the operating device from a remote control center - possibly via a bus system - are called for a signal transmission.
  • the invention also relates to a lighting system, comprising at least two lighting arrangements controlled via a bus line, for example according to the DALI standard, and preferably connected to a central unit.
  • each lighting arrangement can be assigned an individual and / or a group address, wherein the light signals representing the particular operating parameters reproduce the allocated address of the associated lighting arrangement.
  • Different addresses can be reproduced by light signals of different spectrum, in particular different color.
  • the output of the assigned address by means of the light signals may be triggered by a command from the central processing unit or by a manual user activity.
  • the only figure shows a lighting arrangement with a gas discharge lamp, a ballast for this, and an emergency light module with LED light source, all controlled by a (not shown) center of a bus system.
  • the sole FIGURE shows an electronic ballast which controls a gas discharge lamp 2 for illuminating an unspecified space.
  • the ballast 1 draws its electrical energy from the network.
  • an emergency light module 3 fed by a battery 5 becomes active and sets an LED light source 4 into operation.
  • the latter is particularly well suited for emergency lighting operation, because it can be operated with low voltage, in contrast to the gas discharge lamp 2, so that conversion losses are eliminated.
  • the energy efficiency of the LED light source 4 is cheaper than that of the gas discharge lamp 2, which is an important factor in battery operation.
  • Such an operating parameter can be, for example, the result of a self-test of the emergency light module 3, which can be initiated by pressing a button 6 provided on the emergency light module 3.
  • the self-test may, for example, refer to the state of the battery of the emergency light module.
  • the optically output operating parameters can indicate operating states and / or errors of the light source.
  • a self-test can be carried out beforehand by the operating device, which is triggered by an internal control and / or by external signals can be.
  • An example of an error indication is an exceeding and / or falling below of a limit value by the (mains) supply voltage.
  • operating data such as the number or duration of operation of the light source or a component aging can be displayed.
  • These parameters can be determined by means of a counter and / or by means of this parameter determined measuring circuit, wherein the measuring circuit can perform a monitoring measurement.
  • the LED light source 4 is a white light source. In the present example, it consists of three groups of LEDs. The LEDs 4a of the first group are intended to emit red light. The LEDs 4b of the second group are intended to emit blue light. And the LEDs 4c of the third group are for emitting green light. If the LEDs 4a, 4b, 4c of all three groups are driven by the emergency light module 3 for light emission, then the cumulative light emitted by them is white as intended.
  • the display of the operating parameters takes place in the present case in that only a partial number of the LEDs of the LED light source is driven for the optical signal output, the way that they differ from a regular one Illuminate monochrome light or also a buzzing mixed light, which is not white.
  • one or more LEDs 4c can be controlled, which are intended for the emission of monochrome green light.
  • one or more LEDs 4a which are intended to emit red light, can be actuated.
  • An address may be conveyed by one or more selected LEDs destined to emit one of the three colors being driven to flash / blink.
  • the blinking can take place in short or long luminous phases, so that the information is transmitted, for example, with the Morse code.
  • the LED light source instead of producing white light by triples of LEDs 4a, 4b, 4c designed to emit red, blue and green light, it is also possible for the LED light source to consist of only two groups of LEDs together, one of which comprises color-converted white light LEDs, and the other one for monochromatic red light emission, which supplement the color spectrum of the white light LEDs to produce a white sum light that is closer to room lighting requirements than the white light emitted only by the white light LEDs. Because white light is not monochromatic, there are many variants of it. It is important in this context that the LEDs which are intended for the emission of red light are activated for the signal output.
