Definitions

  • the invention relates to a circuit arrangement for adjusting the brightness current-controlled light-emitting diodes for illuminating a display, in particular for illuminating displays, buttons and switches in vehicles.
  • the Proposed circuit arrangement can be both active for control Display elements as well as backlighting or lighting be applied.
  • Active display elements can e.g. segment displays or status display fields of an instrument cluster in the dashboard of a Vehicle.
  • the invention is based on an arrangement according to DE 196 02 891 A1.
  • the determination and adjustment of the Correction factor is carried out with the help of a light meter, which by the Illuminant emitted brightness measures, as well as using an over connect a diagnostic interface to the control unit of the display external test computer.
  • the measured brightness value is shown with a Compare the table value in a memory belonging to the display is deposited.
  • the correction factor can also be limited to a table value Map that characterizes the lighting characteristics of the lamp, be removed.
  • Map that characterizes the lighting characteristics of the lamp
  • the one taken from a table or a map Correction factor is then used to control the lamp influenced by a change in current or voltage such that the measured brightness value at the setpoint value specified in the memory Brightness value is adjusted.
  • the setting made in this way the control of the illuminant should according to DE 196 02 891 A1 for the The lamp's service life is preserved.
  • DE-A 195 40 326 is a headlight for vehicles with a gas discharge lamp as a light source with an electrical Ballast device for the gas discharge lamp is known, which the gas discharge lamp to operate with electric Power supplied. This ballast detected the cumulative total operating time of the gas discharge lamp and supplies the gas discharge lamp with increasing total operating time with higher electrical power.
  • control unit can also Information about the electrical power and / or the operating temperature of the LEDs are detected and registered, so that the determination of the Degradation value for setting the control current for the LEDs according to the data stored in the memory for the Degradation behavior not only depending on the registered Operating time, but also depending on the electrical Power and / or the operating temperature of the LEDs can take place.
  • the degradation value for setting the Control current for the light emitting diodes should only be dispensed with then if that is from the control unit via the input interface recorded signal for the desired brightness of the LEDs relative is constant, i.e. if one during the period of use of the display Change in the brightness of the LEDs once set not to expect or is not provided.
  • the inclusion of the operating temperature of the LEDs is therefore one quite reasonable option because aging, i.e. the degradation behavior the light-emitting diodes is temperature-dependent to a considerable degree and with many especially the automotive applications for the proposed Circuit arrangement with an operation in a wide temperature range with frequent temperature fluctuations must be expected.
  • the solution found can be designed such that the Degradation behavior of the data reflecting light-emitting diodes not only in Form of individual discrete and therefore relatively less punctual values in the Storage can be stored, but in the form of a data sheet taken curve or by a formula or by parameters for a specific, but not detailed here, the Degradation behavior descriptive algorithm, whereby the of the Control unit to determine the degradation value in even finer coordination can reflect the actual degradation behavior of the LEDs. In this way, a possibly with the proposed tracking of Control current associated undercompensation or overcompensation the degradation behavior for the LEDs avoided even better become.
  • the main advantage of the solution found is that a constant brightness of the LEDs during a reasonable The service life of the display can be ensured without this external measuring equipment or test equipment are required.
  • the control current of the light emitting diodes is based on a Degradation value tracked that the brightness of the LEDs for one Users of the ad despite their physical and therefore unavoidable degradation behavior remains constant.
  • the update takes place in that the Control unit as the operating parameters of the LEDs their operating time and preferably also registers the electrical power with which the LEDs have already been operated, and then based on those in the memory stored data that characterize the degradation behavior, which degradation value is typically based on the registered Operating parameters currently results.
  • This update of the degradation value will only be carried out in practice at reasonable intervals in order to Control unit not overly burdened with calculations.
  • the control unit saves the determined Degradation value preferably in one assigned to the control unit Memory and performs all desired until the next update Brightness settings for the LEDs based on this currently applicable Degradation value through by the control unit the control current for the Set the light emitting diodes taking this degradation value into account.
  • the Control current for the LEDs is inversely proportional to Degradation value tracked.
  • the Control current is initially set so that a tracking of his Amount is possible without overdriving the LEDs.
  • the working range for the control current of the LEDs must therefore be chosen be that the limit of the LEDs by tracking the Control current during the planned period of use of the advertisement if possible is not reached.
  • the proposed Circuit arrangement intercepting the initially strong degradation Burn-in for the LEDs is unnecessary.
  • the collection and registration of information about the for the determination of the operating parameters required in each case i.e. the Information about the operating time, the electrical power and / or the Operating temperature
  • the Information about the operating time and the electrical power of the LEDs therefore generally no independently working sensory measuring equipment needed because the control unit through appropriate programming both the duration of the current flow to the LEDs as well as an indication of can register the amount of the control current.
  • the control unit can easily the electrical power of the LEDs as soon as they indicate the amount of the Control current can fall back. Because the control current is direct in many cases is provided by the control unit, the control unit only needs by storing a corresponding information in the one assigned to it Memory to register how much of it in a given unit of time provided control current was. Once the control unit does that Behavior of the one provided by her at her exit Control current logged, essential information about the Operating parameters are available to work with them based on the in memory stored data on the degradation behavior of the LEDs the current To determine the degradation value. As a really additional measuring device to the already existing components for the proposed Circuit arrangement is only one near the light emitting diodes arranged temperature sensor required to give an indication of the Win operating temperature of the LEDs, then this information is fed to the control unit for further processing.
  • the ones to be stored in the memory connected to the control unit Data for setting the control current of the light emitting diodes can be found at Manufacturing process of the display to be illuminated with the light-emitting diodes get saved. All you need is the manufacturer 's information LEDs in the form of suitable data in the memory of the Circuit arrangement to transmit. This data can be very easily through an appropriate program selection to the exact specification of the Adjust used LEDs so that always optimal for each display Data are used. This also makes the Manufacturing process for a generic display simplified because a depending on the component-specific specification the selection in the Manufacturing process of the display used LEDs can be omitted.
  • the proposed solution will be briefly explained again using a simplified block diagram.
  • the figure shows a display 1 with light-emitting diodes, the control current of which is set by a control unit 2.
  • the control is to be carried out by means of a pulse width modulated signal (PWM).
  • PWM pulse width modulated signal
  • the control could of course also take place analogously with a continuously running current.
  • the control unit 2 receives a signal via an input interface 6 is a measure of the desired brightness of the LEDs. That about the Input interface 6 recorded signal can be from a dimmer be tapped with which the desired brightness for the LEDs from User of display 1 is set. However, this signal can also be a default value that e.g. via a CAN data bus from another control unit to the one containing the display 1 Device is transferred. To meet this requirement for brightness in the sense of The objective of responding appropriately for this invention is the Control unit 2 taking the control current into account Degradation value.
  • the control unit records and registers 2 the operating time of the LEDs and preferably also their electrical power and - if necessary - its operating temperature.
  • the control unit 2 can signal a near the light emitting diodes arranged temperature sensor 5 are supplied. The information about the recorded operating parameters are fed to the control unit and there continuously accumulated and updated and in one of the control unit 2 assigned memory 7 filed.
  • the control unit 2 now checks using the current information on at least one of the recorded operating parameters, what degradation value to you based on the data stored in memory 7 is assigned to the degradation behavior of the LEDs and provides this Degradation value then for a corresponding setting of the control current to disposal. Whether the control unit receives the control current directly at its output or via suitable drivers is for the present invention not significant. In practice, you don't get the degradation value all the time, but only update at reasonable intervals, e.g. in Depending on the load on the LEDs, it may be daily or depending on brightness reductions in the respective Operating environment of the display from the human eye at all as different brightnesses can be perceived.
