Definitions

  • the invention relates to a method for operating an arrangement designed to emit light whose brightness and/or color location can be adjusted and which has at least two electrically controllable LED light sources which differ from one another in a dominant wavelength of the light they generate in each case, wherein the light emitted by the arrangement is generated by additively mixing the light generated by the individual LED light sources, the LED light sources being supplied individually in such a way that a predetermined dominant wavelength of the light emitted by the arrangement is independent of the respective brightness of this light is constant and/or that a predetermined brightness of the light emitted by the arrangement is constant independently of the respective dominant wavelength of this light.
  • the invention also relates to a system for generating light whose brightness and/or color location can be adjusted, having at least one arrangement for emitting light whose brightness can be adjusted and at least one electronic control unit configured to control the arrangement, the arrangement having at least two electrically has controllable LED light sources which differ from one another in a dominant wavelength of the light they generate in each case, the LED light sources being designed to be controllable and arranged in relation to one another in such a way that the light emitted by the arrangement is produced by additively mixing the light emitted by the individual LED Light sources each light generated is generated, the control unit being set up in such a way that the LED light sources are supplied individually in such a way that a predetermined dominant wavelength of the light emitted by the arrangement is independent of the respective brightness of this light s is constant and/or that a predetermined brightness of the light emitted by the arrangement is constant independently of the respective dominant wavelength of this light.
  • a dominant wavelength provides a way of describing a polychromatic mixture of light in terms of a monochromatic light that produces a similar hue perception to the polychromatic mixture of light.
  • a line which corresponds to that in the white point contained in the CIE chromaticity diagram and a point representing the color of a polychromatic light mixture produced by a light source can be extrapolated in such a way that the line intersects the edge of the CIE chromaticity diagram at two points of intersection.
  • the point of intersection that is closer to the point for the color of the polychromatic light mixture represents the dominant wavelength of the color of this light mixture as a wavelength of a monochromatic light or a certain pure spectral color.
  • the dominant wavelength depends on the entire course of the optical spectrum, which the light to be characterized with regard to the color locus has.
  • a spectrum is often characterized by Parameters such as peak wavelength and FWHM are described.
  • the color locus is only clearly defined by these parameters if further information about the spectrum is known, such as symmetry properties. For example, if an LED has a Gaussian curve, the spectrum and thus the dominant wavelength is clearly determined by specifying the peak wavelength and the half-width. However, this does not apply to any other, in particular asymmetrical, spectra. For this reason, in the present description, the color locus is described by the dominant wavelength and not by other spectral parameters.
  • Arrangements for emitting light whose brightness can be adjusted which have at least two LED light sources, are known.
  • This pulsed driving of corresponding arrays causes the light emitted by the arrays to be pulsed.
  • the dominant wavelength or the color locus in the CIE standard chromaticity diagram of a light generated by an LED light source is highly dependent on the amperage of the current with which the LED light source is supplied. Not only the peak wavelength can change, but also the shape and/or the width of the spectrum.
  • the amperage of the current supplying the LED light sources is constant during a pulse width, as a result of which the light generated by the LED light sources of the arrangement or the light emitted by the arrangement during a pulse width is essentially a constant dominant wavelength or has a constant color locus.
  • a disadvantage of the conventional arrangements is that the pulsed light emitted by these arrangements is unsuitable if it leads to undesirable effects when used. This is the case in particular when such lighting is used for film recordings, since the frequency of the pulsed light with the image refresh rate can lead to beats. This effect could be eliminated by synchronizing the pulse frequency of a light emitted by the arrangement with the frame rate, ie the frame refresh rate with which the images of a film recording are generated. However, this would lead to an undesirably high level of technical complexity.
  • the different pulse widths of the different LED light sources can lead to disturbing image segments with the wrong color or black stripes in the image display.
  • long-term exposure to pulsating light with frequencies ⁇ 1 kHz is perceived by the human eye as disturbing and questionable in terms of well-being.
  • the object of the invention is to make it possible to emit a light that can be adjusted in terms of its brightness and/or its color location with an arrangement of the type mentioned at the outset, in which the above-mentioned disadvantages do not occur.
  • the LED light sources of the arrangement are supplied with a direct current, ie with an unpulsed current, so that the light emitted by the arrangement is not pulsed—as is conventional—but is continuous. This avoids the disadvantages described above with reference to the prior art. Controlling the brightness and/or the color locus of the light emitted by the arrangement is achieved by controlling the current strength of the direct current individually supplying the individual LED light sources.
  • the LED light sources are supplied with direct current in such a way that a predetermined dominant wavelength of the light emitted by the arrangement is constant regardless of the respective brightness of this light or - in the entire range in which the brightness of the light, i.e. the photometric radiant power (i.e the luminous flux measured in lumens) can be adjusted only varies by a predetermined maximum amount.
  • the set dominant wavelength or the color locus of the light emitted by the arrangement is always the same, regardless of the brightness set in each case. This can be achieved by individually supplying the individual LED light sources of the arrangement with direct current.
  • the LED light sources are individually supplied with direct current in such a way that a predetermined brightness of the light emitted by the arrangement is constant regardless of the respective dominant wavelength of this light or - in the entire range in which the brightness of the light, i.e. the photometric Radiant power (i.e. the luminous flux measured in lumens) can be adjusted, only varies by a predetermined maximum amount.
  • the set brightness of the light emitted by the arrangement is always the same, regardless of the respective, in particular changeable, dominant wavelength of this light. This can be achieved by individually supplying the individual LED light sources of the arrangement with direct current.
  • An arrangement operated according to the method according to the invention can also have three or more LED light sources.
  • a plurality of LED light sources, in particular connected in series with one another, can also be present from each type of LED light source.
  • the arrangement can be set up to emit colored, white and/or variable light in terms of its color locus.
  • the LED light sources of the arrangement can be supplied with a direct current by means of a driver circuit, the current intensity of which can be set via the driver circuit, but is kept constant at a desired value after the respective setting.
  • At least one LED light source is supplied with direct current, taking into account a predetermined dependence of the dominant wavelength of the light generated by this LED light source on a current intensity of a direct current supplying this LED light source.
  • a characteristic can be used for this purpose, which reflects the dependency of the dominant wavelength of the light generated by the LED light source on the current intensity of the direct current supplying this LED light source.
  • Such a characteristic curve can additionally contain a predetermined dependency of the dominant wavelength of the light generated by the LED light source on a temperature of this LED light source and/or on a temperature of the arrangement.
  • the predetermined dependency can contain coordinates of the CIE standard color table with regard to the dominant wavelength or the color locus of the light generated by the respective LED light source.
  • the individual drive currents for the individual LED light sources can be determined in a variety of ways from the individual characteristic curves or characteristic curve fields for all individual LED light sources .
  • a multidimensional dependency of the luminous flux which defines the brightness, of the light generated by the entire arrangement can be established from the associated individual drive currents for the individual LED light sources.
  • a value for the luminous flux can then be specified with a manipulated variable (e.g. the resistance value of a potentiometer or a digital value of a control signal).
  • the individual drive current for the individual LED light sources can then be determined immediately from the known dependency and selected or set accordingly.
  • the multidimensional dependency can also include and take into account the temperature dependency of the dominant wavelengths of the individual LED light sources. The aging or degradation of the LED light sources can also be taken into account in this way.
  • the brightness control can also be effected in such a way that an LED light source, which can be referred to as a lead LED light source, is supplied with an arbitrary current. Since the dependency of the dominant wavelength of this guide LED light source is known, all other LED light sources can be controlled with a direct current selected in such a way, taking into account their dependencies of the respective dominant wavelength on the respective supply direct current, that the specified dominant wavelength of the entire arrangement emitted light remains constant or only fluctuates within a tolerated value range. Here, therefore, it is not the luminous flux of the light generated by the entire arrangement that can be specified, but rather the amperage of the drive current for the guide LED light source.

  • the luminous flux PHI measured in lumens, can also be used for the brightness Q.
  • a normalized brightness for example between zero (or a lower limit, e.g. 10% of the maximum achievable brightness) and 100% of the maximum achievable brightness (this can also depend on the color point).
  • the currents I 1 to I n are real independent parameters (within specified value ranges).
  • the parameters ⁇ d and Q depend on the independent parameters I 1 to I n and result from the independent parameters.
  • the parameter T is also not completely independent of the independent parameters I 1 to I n .
  • the independent parameters I 1 to I n influence the junction temperature of the respective LED light source 1 to n.
  • the respective junction temperature also depends on the respective ambient temperature and the respective heat transfer resistance, which is decisive for the release of heat from the respective junction to the environment is.
  • starting values for currents I0 1 to I0n can be determined as a function of specified values for the color locus or ⁇ d and the desired brightness Q (eg 80% of the maximum brightness). These starting values can be taken from the large characteristic diagram for a normal temperature T, for example. Instead, a separate characteristic map can be used for this, which links the values for I0 1 to I0 n , ⁇ d and Q for a specific temperature T (eg room temperature).
  • the influence of temperature can then be taken into account, where a temperature sensor 7 supplies a temperature value which initially deviates from an initial temperature. New values for the direct currents I 1 to I n for the new temperature value can then be taken from the characteristics map, or from a separate characteristics map, and the LED light sources 1 to n can be controlled accordingly.
  • the second step can also be divided into two sub-steps, with only the temperature influence on the direct currents I 1 to I n being corrected in a first sub-step in order to retain ⁇ d .
  • a characteristic map used for this purpose can only take into account the temperature dependency, without taking into account the influence of the changed direct currents I 1 to I n on the color locus of the light emitted by the arrangement 2 .
  • Such a characteristic field can be sufficient for the control/regulation of LED light sources 1 to n driven in a pulsed manner since there is no dependence of the color locus of the light emitted by the arrangement 2 on the direct currents I 1 to I n of temperature effects.
  • the changed direct currents I 1 to I n can then be corrected by means of a further characteristic diagram, in which the dependence of the color locus of the light emitted by the arrangement 2 on the direct currents I 1 to I n is taken into account, so that the desired Color point of the light emitted by the arrangement 2 is achieved or maintained.
  • the changed direct currents I 1 to I n will then again have an influence on the temperature T, etc. In the manner described, a desired state of equilibrium can be achieved after three such iterative steps.
