Definitions

  • the present invention relates to a method and a device for carrying out a functional test of a lamp of a luminaire for lighting or display purposes.
  • the lamp comprises at least two lamps that can be switched to a first or a second state. In the first state, the illuminants emit a first light output specific to the illuminant. In the second state, they emit a specific second light output. The first light output is greater than the second light output.
  • the lamps can preferably be LEDs.
  • LEDs light-emitting diodes
  • vehicles with autonomous or semi-autonomous states require, for example, an illuminant or LED diagnosis capability in the case of optical status displays (for example LED light strips).
  • optical status displays for example LED light strips.
  • At least the states "LED lights up” or “LED does not light up” should be able to be recognized in order to avoid failures Diagnosing and recognizing LEDs so that the user or driver can be informed and the affected LEDs can be replaced.
  • DE 100 18 760 A1 discloses a circuit for monitoring the function of a light emitting diode.
  • a disadvantage of the prior art is that the actual function of the light emission or the light emission of the lamps is not checked.
  • the object of the present invention is therefore to propose an improved method for precisely checking the function of a lamp, in particular an LED, which in particular avoids the disadvantages known from the prior art.
  • the method according to the invention for carrying out a functional test of a lamp of a lamp for lighting or display purposes requires at least two lamps.
  • the functional state of a lamp is determined, a possible functional state being a defect and the state thus meaning "defective".
  • Another functional state reflects the correct functioning of the lamp and is referred to as "intact”.
  • the functional state thus allows a statement to be made about the illuminant, in particular about its luminous emissivity.
  • the illuminants required for the method can be wired in such a way that they emit a specific first light output in a first state and emit a specific second light output in a second state.
  • the first light output is greater than the second light output.
  • “specific light output” means a light output that is related to the respective illuminant.
  • the light output can therefore depend on the type of illuminant and can be different for each illuminant.
  • the specific light output can depend on the respective LEDs or illuminants, for example depending on whether it is a blue, red or green LED.
  • the first illuminant is switched to the first state.
  • the second illuminant is switched to the second state.
  • a measured value of an electrical parameter caused in the second illuminant is measured, the measured value being caused by the first light output of the first illuminant.
  • the measured value is evaluated so that a functional state can be determined.
  • the functional state of one of the two lamps is detected, which allows a statement about the light emissivity of the lamp.
  • a third illuminant is used, which can also be switched to a first or second state in which a first or second light output is emitted.
  • the first light output is greater than the second light output.
  • the third illuminant is also switched to the second state, in which a specific second light output is emitted.
  • a measured value of an electrical parameter is determined, which is caused by the first light output emitted by the first illuminant in the third illuminant.
  • This measured value referred to as the second measured value, is evaluated, whereby it can optionally be related to the (first) measured measured value of the second illuminant. From the second measured value of the third illuminant and the measured value of the first illuminant, conclusions can be drawn about the functional state or a possible error of one of the three illuminants.
  • a defect of the first illuminant is recognized if the measured values of the second illuminant and / or the third illuminant lie below a threshold value specific for the respective illuminant.
  • the threshold value is preferably set such that a measured value that lies above the threshold value represents an intact state of the illuminant. A light output radiated in from outside is recognized in the respective illuminant, since the measured value lies above the threshold value.
  • the first illuminant radiates with the first light output into the other illuminant (s), the measured value detected in the respective illuminants remaining below the threshold value, it can be assumed that the first illuminant has not emitted sufficient light output. It can thus be concluded that the first illuminant is defective and in particular that the first illuminant is faulty or defective.
  • the functional state of the second lamp which is switched to the second state, can be determined. If the measured value measured in the second illuminant lies below the specific threshold value and at the same time the measured value measured in the third illuminant lies above the specific threshold value, there is a defect in the second illuminant.
  • the third illuminant has recognized the emitted light output of the first illuminant because the measured value lies above the threshold value. At the same time, however, the second illuminant receives no or too little light output, so that the measured value remains below the threshold value. A malfunction of the second illuminant can be recognized from this.
  • an intact behavior and complete functionality of the first illuminant is recognized if the measured value is above the respective specific threshold value in the two other illuminants which are switched to the second state, that is to say the second and third illuminants.
  • the second and third illuminants recognize the emitted light emission from the first illuminant.
  • the intact function and emissivity of the second and third lamps are detected because they absorb enough light.
  • the functional state of one of the two lamps switched into the second state is recognized as intact if the difference between the measured value measured and the associated specific threshold value has the same sign for both lamps. Either the measured value lies above the respective threshold value, so that the light emission emitted by the first illuminant is detected, or both illuminants (second and third illuminant) do not detect any light emission, the two illuminants being classified as intact. If the measured values of both lamps are below the threshold value, it can be concluded that the emitting lamp or LED is faulty.
  • the second light output of the lamps is so low that there is no or significantly lower light emission than the first light output of the lamps.
  • the second light output of each lamp is preferably lower than the first light output of any lamp.
  • a significantly lower light output or significantly lower light emission in the second state means in Within the scope of the invention, that a light output radiated by the light emission of a lamp in the first state into a lamp is greater than the (significantly lower) light output of the received lamp, in particular an LED.
  • the light output received in a light source which is switched in the second state and emits a second light output is preferably so much greater that a predetermined signal-to-noise ratio is achieved, for example that the received light output is larger, preferably significant and distinguishable in practice is greater than the emitted light output of the illuminant in question. In this case, it can be guaranteed that a received light output is detected and recognized as such.

  • the LEDs used particularly preferably emit all different colors.
  • the first LED emits a blue color
  • the second LED a green
  • the third LED a red color.
  • the LEDs preferably have different focal wavelengths, the focal wavelength being the wavelength in the wavelength spectrum at which an intensity maximum of the corresponding LED or the corresponding light source occurs.
  • the electrical parameter measured in the method is preferably a photo voltage or a photo current.
  • the photo voltage is the voltage applied to the LED, which is generated by a photo current that arises due to the received emission of light. In the case of an LED, the photo voltage is sometimes also called LED voltage.
  • the product of photo current and photo voltage corresponds to the light energy converted into electrical energy in the irradiated LED or illuminant.
  • the energy is preferably measured with an external impressed voltage of 0 volt (0 V) as pure photo current or with an external impressed current of 0 ampere (0 A) as pure photo voltage.
  • the person skilled in the art can also determine the energy generated in other operating points, the determination being more complex is.
  • Photo current and photo voltage can be used as a measure of the light output that shines on a lamp or an LED.
  • the lamp has two groups of lamps, each group of lamps comprising at least one lamp and one lamp of the first group of lamps being switched to the first state and one lamp of the second group of lamps being switched to the second state.
  • the functional state is therefore detected between two groups of lamps.
  • a lamp in which at least two groups of lamps each comprise three lamps.
  • a lamp of the first group of lamps is switched to the first state, while a lamp of the second group of lamps is switched to the second state.
  • Two lamps of the second group of lamps are preferably switched to the second state; all lamps of the second group of lamps are particularly preferably switched to the second state.

  • the LED can also be switched to the second state and emit no light or an insufficiently large amount of light for measurement in an adjacent LED.
  • at this time at least one other LED must be in the on state, i.e. emit light (with a sufficiently large light output), which also corresponds to the second state of the illuminant.

  • this electrical parameter is preferably a photo voltage of the second LED, which it generates as a result of the irradiation, or a photo current of the second LED, which generates as a result of the irradiation.
  • the value of the selected parameter depends on the lighting in the form of the light output radiated into the second illuminant. Irradiation brings the second illuminant into a state in which this dependency can be measured.
