    The invention relates to an electric lighting device, in particular electric lighting candle, with a luminous body and a light source, wherein the luminous body is formed as a cloudy glass.
    It has long been known in the prior art to replace candles with electric lighting devices - so-called electric lighting candles - especially since they are easier to handle and safer to use than conventional open-flame candles. In this regard, the imitation of the flame by the lighting device is difficult.
    The AT 11037 U1 shows a luminous candle, in which a luminous body is arranged in the form of a ram above a candle shaft, wherein a cavity is provided in the interior of the luminous body, at the boundary surfaces light from the candle shaft is totally reflected in the lateral direction.
    The AT 411 847 B represents an electric lighting device in the form of candles, in which the light emitted by a light source at least partially passes through a candle shaft in the above lying light section. The luminous portion has a shape such that the light exits mainly in the acute region of the luminous portion, since the geometric conditions for total reflection are no longer met here.
    With these lighting devices, however, it is only possible to imitate the geometric Abstrahfcharakteristik a candle. An imitation with regard to the flickering of a flame can also be achieved by a corresponding control of the LEDs.
    The object of the invention is to further improve the above lighting devices and to take into account in particular in the imitation of a flame also existing in a flame Temperaturgradlenten and the associated spectral emission characteristics.
    This is achieved by an electric lighting device having the features of claim 1. 68500 35 / sk 01/10 2010 FR 10:04 [SE / EM NO 5713] ®008 07/26 ^ 01/10/2010 09:02 + 43-512-563408 TORGGLER & HOFINGER page 4 4 · '»· t ··············································································································································································································· M * ·· · * " 2
    The electric lighting device has a luminous element and a light source, wherein light emitted by the light source is emitted via the luminous element into free space. The electrical Beieuchtungsvorrichtung may be formed in particular as an electric candle, wherein the luminous element in this case has a candle shaft and arranged at one end of the candle shaft luminous portion.
    The luminous body is formed as a turbidity, wherein the haze of this glass is achieved by arranged in a base glass opacifier. According to the invention, it is now provided that the luminous element has such a material thickness, at least in a direction of propagation of the light emitted by the light source, that a color conversion of the luminous element irradiated by the light source occurs in this propagation direction in the luminous element.
    The invention has realized that the opacifiers arranged in the base glass serve as scattering centers, whereby the short-wave part of the light emitted by the light source is preferably scattered by means of Rayleigh scattering. The longer, therefore, the path is at least in a propagation direction of the light emitted by the light source through the opaque glass, the more is scattered by the high-frequency component of the light, while the low-frequency component is less affected by the turbidity, so that the spectral composition of emerging from the luminous body Changes light along this direction of propagation, whereby the irradiated by the light source luminous body does not emit in a homogeneous color. In particular, along the propagation direction in which the material thickness is correspondingly large, a color gradient results when the illumination device is in operation.
    It is - except for the light in the body always present absorption of the light - the amount of light emitted by the light source is not significantly reduced by the filament. For this reason, the spectral composition of the total light emitted by the illumination device is also only insignificantly changed. Due to the turbidity, however, the portions of the light are selectively scattered on their way through the luminous body and, after this scattering, emerge from the luminous element at different points, so that the spectral composition changes along the luminous element and thus the color gradient according to the invention is divided. The local spectral composition of the light emitted by the luminous element is thus changed. The total amount of light emitted by the illumination device corresponds, except for the abovementioned absorption, to the amount of light emitted by the light source. 01/10 2010 FR 10:04 [SE / EM NO 5713] @ 007 01/10/2010 09:02 + 43-512-583408 TORGGLER & HDFINGER ......... s. 08/26 -1 • * * * * ** 3
    The so-called milky or opal glass bulbs known in the art are so thin that $$ such an effect is undetectable to the human eye. Such light bulbs made of milk or opal glass serve only to block off a portion of the light generated by the filament and to reduce the glare,
    In contrast, the invention has realized to use the above-described scattering effect to produce a color gradient when operating in the lighting device, by the filament has such a material thickness that a qualitative effect is recognizable to the human eye.
    Thus, with an appropriate selection of the light source, an elongated luminous element, for example in the lower region, which is arranged closer to the light source, can shine blue. Along the direction of propagation of light more of the short-wave blue portion of the light is scattered medium by the turbidity, so that with sufficient material thickness of the filament of the light source farther away end of the filament glows reddish. When the lighting device is not in operation, no color gradient can be detected in the case of homogeneous turbidity. This only results. when the light source of the lighting device is in operation.
    As a measure of the color impression of a light source, the Correlated Color Temperature (CCT) can serve, which is defined as the temperature of a black body, which belongs to a specific light color of this radiation source, which temperature prevails at the same brightness and under observation conditions closest to the color to be described.
    In addition, the Color Rendering Index (CRI) is a photometric quantity that can be used to describe the quality of the color reproduction of light sources with the same correlated color temperature.
    If, in a propagation direction of the light, a sufficiently high material thickness of the luminous body, consisting of turbid glass, is present, so that a visible color conversion takes place for the human eye, this means that light which propagates laterally in this propagation direction, e.g. Depending on the distance of the light source from the exit point of the luminous body has a different color, so that in a measurement of the correlated 01/10 2010 FR 10:04 [SE / EM HP. 5713] @ 008 01/10/2010 09:02 + < 33-512-583408 TORGGLER & HOFINGER p. 09/28 " 7

    Color temperature or the color rendering index of light emerging from the luminous body such a change along the filament in this
    Propagation direction results, which is also comprehensible to the human eye.
    Further advantageous embodiments of the invention are defined in the dependent claims.
    In one embodiment of the invention, the luminous body has an oblong shape, so that a longitudinal direction exists and the extension in the longitudinal direction exceeds the dimensions of the filament in perpendicular directions, the illuminating device is designed such that light is emitted from the light source in the direction of this longitudinal direction , there is sufficient material thickness so that there is a sufficient number of dispersing opacifiers to provide visible color conversion.
    Although a visible color conversion already takes place at a material thickness of at least 5 mm, depending on the degree of turbidity, which represents a measure of the density of the opacifiers in the luminous body, it is preferable to use an elongated body with a longitudinal extent of between 10 and 100 mm to use the lighting device.
    The average diameter of a filament of elongated shape may be between 10 and 30 mm, with no necessarily constant diameter. Sexy optical and aesthetic effects can be realized by elongated bodies, which are not constant in cross-section along the longitudinal direction, and which have a longitudinal curvature.
    Another aesthetic effect, with which the imitation of a candle can be further improved, results when the filament has a stylized flame shape. A facetted ground luminaire results in further attractive refraction effects at the edges between the facets. In addition, a facetted ground luminaire looks visually appealing even when the lighting device is not in operation.
    In a preferred embodiment, the luminous body is formed as a solid body, which can be realized in a simple manner, the necessary material thickness in a propagation direction of the light. The light source can be placed at one end of the filament. 01/10 2010 FR 10:04 [SE / EM NR 5713] @ 009 01 / 1.0 / 2010 09:02 + 43-512-583408 TORGGLERSHOFINGER Ξ. 10/26 • · · * • »» *

If a part of the luminous element is in the form of a candlestick, on the outer wall of which the light rays propagate by means of total reflection to form a luminous portion, or if the outer wall is mirrored, then the light source can be arranged below the candlestick. However, it can also be provided to provide one or more recesses for arranging light source (s) in the luminous element or in the candlestick.
    The light source is preferably designed in the form of one or more light-emitting diodes. Light-emitting diodes are characterized by their compact size, low energy consumption, low heat emission and long service life. In the case of several light emitting diodes can be provided that these LEDs emit light of the same color. However, it can also be provided that light-emitting diodes are used which each emit light of a different color. In particular, it can be provided that the color and / or the brightness or intensity of the emitted light of the light source, in particular of the light emitting diodes, can be varied with a control device.
    In a further embodiment of the invention, an optical element is arranged between the luminous element and dBr light source. This optical element is at least partially transparent to light of the visible spectrum and also has a number of scattering centers, from which light of a certain wavelength is scattered. This reduces the proportion of light in this spectral region that reaches the luminous element. The optical element serves as a "pre-wire". It can serve to reduce the color temperature and the luminance of the radiation used in the luminous body, provided that the scattering centers preferably scatter light higher frequency. In this case, this optical element may be arranged in a housing of the illumination device, so that it is not recognizable under normal viewing angles. The optical element can also be part of the luminous element or even formed integrally with the luminous element. In particular, this optical material can be made of the same base glass as the luminous body, and also be mixed with opacifiers. The degree of turbidity of the optical element can be substantially the same as the turbidity level of the luminous element but also different.
    In the region of the light source and of the adjoining part of the luminous element, a reflector can additionally or alternatively be arranged in order to deflect the radiation scattered in this region of the luminous element from the luminous element and, if appropriate, the radiation which is scattered by the optical element acting as prefixer. This distraction can then be reduced to 01/10 2010 FR 10:04 [SE / EM HR 5713] @ 010 01/10/2010 09:02 + 43-512-583408 TGRGGLERSHOFINGER · * s. 11/26 ^ • ft

In one embodiment of the invention, the luminous body has a substantially homogeneous turbidity. This is achieved by a homogeneous distribution of the scattering centers in the luminous body. As a result, an equal proportion of short-wave light is scattered along the entire luminous body.
    Alternatively, the luminous element may have a turbidity profile, that is to say a turbidity varying in particular along a longitudinal direction of the luminous element. This is achieved by an inhomogeneous concentration of clouding agents in the luminous body serving as scattering centers. This makes it possible, for example, to distribute the scattering centers in such a way that initially only very little light is scattered with high-frequency radiation, while in the region of the end of the luminous body remote from the light source, this scattered fraction increases. As a result, particularly attractive optical effects can be realized. In addition, such a turbidity profile can be seen even when not in operation lighting device.
    In homogeneous turbidity as well as in a turbidity course, the luminous body can have an almost invisible opal color, an opaline or cloudy milky appearance, alabaster-like or a pure white color when the illumination device is not in operation. In addition, it may be provided additionally to color the luminous element, whereby the color conversion produced by the opacifiers acting as scattering agents in the luminous element is changed, for example because the additional color applied to the luminous element as a color layer filters out a spectral component dependent on the color layer. By an additional coloring of the entire filament, for example by introducing special dyes into the melt to produce the filament, the color conversion produced by the opacifier is also changeable.
    The degree of turbidity, i. the concentration of opacifiers in the luminous body, can be selected depending on the geometric shape of the filament to achieve a desired effect. 01/10 2010 FR 10:04 [SE / EM NO 5713] @ 011 01/10/2010 09:02 + 43-512-583406 TORGGLERSHOFINGER s. 12/26 ή «« * * * * «4 7
    The turbidity of the luminous body can be effected by clouding the constituents of a base gas with opacifiers, e.g. be incorporated in the form of solid particles. Preferably, these are fluorine carriers. In particular, these fluoro-promoters may comprise cryolite. In the course of the fusion of the components of the base glass, solid particles, which arise from the admixed substances, embed themselves in the glass. As a result, the glass becomes cloudy, with the embedded particles, after shaping and curing of the glass, acting as scattering centers for light propagating in the luminous body.
    In the case of fluoro-carriers, e.g. Sodium fluorides excreted, which are then ultimately responsible for the turbidity. However, it is also possible, as clouding agent, to incorporate non-dissolving, hard-fusing oxides such as SnOs, T1O2 or ZrOz into the base glass and thereby to produce a desired opaque glass.
    In a further embodiment of the invention, the opacifiers are in the form of an emulsion, which is formed by the formation of at least two glass phases in the addition of phosphates or other emulsion formers.
    The basic glass is preferably lead-free glasses are used, wherein a turbid glass according to the invention can also be produced with lead-containing base glasses. An example of the possible constituents of a base gas and of possible opacifiers together with their respective percentages by weight is listed in the following table:

    If an additional coloring of the opaque glass is desired, it is possible to add to the base glass per se known, coloring constituents in the customary dosages, for example cadmium or copper oxides, for a red coloring.
    In addition, by means of certain additives incorporated in the base glass, the opacifier may have desired physical properties, e.g. a certain refractive index or coefficient of expansion. Such additives are e.g. La, Nb, Ta, Y, Rb, Sc, W or Bi.
    The invention further relates to a luminous element for a lighting device as explained above, wherein the luminous element is designed as described above.
    The invention further relates to a method for producing a luminous body as described above, wherein the constituents of a base glass are mixed with opacifiers and then fused.
    Although a certain turbidity may be present even after these process steps, it may further be provided to carry out a further temperature treatment step after cooling of the fused substances, wherein the cooled fused substances are in turn heated to a certain temperature for a certain time. This temperature treatment step is generally known as tempering. By starting, the turbidity is adjusted to a desired extent. In the case of a turbidity course, it may be provided, for example, to make the turbidity of the illuminating body almost unclouded to almost opalescent running along the illuminating body. If the outer geometric shape of the luminous element is already produced before tempering, the tempering process also serves to adapt the turbidity to the geometry of the luminous element. The design can also be done after or during the annealing. 01/10 2010 FR 10:04 [SE / EM HR 5713] @ 013 01/10/2010 09:02 + 43-512-58340B TORGGLER & HOFINGER 14/26 7 01/10/2010 09:02 + 43-512 -58340B TORGGLER & HOFINGER 14/26 7

    In one embodiment of the invention, the tempering is carried out at a temperature which is between the transformation temperature of the base glass and a temperature which is 100 ° C above the transformation temperature of the base glass. The transformation temperature corresponds to the temperature of the transformation point and depends on the constituents of the glass. In this case, the transformation temperature may also correspond to a certain temperature range, since the transformation of the glass occurring at the transformation point does not necessarily take place at a single point, but also within a certain narrow range.
    Further details and advantages of the present invention will be explained in more detail below with reference to the description of the figures with reference to the drawings. It shows:

    Diagrams of FIGS. 3a to 3c,
    2, and FIG. 4 shows a schematic representation of the measuring arrangement for measuring the correlated color temperature of the light rays emerging laterally from a luminous element
    1 shows a lighting device 1 according to the invention, comprising a housing 3, in which a light source 5, preferably comprising one or more light emitting diode (s), and a luminous body 2 having an elongate shape. The light source is shown purely schematically. The luminous element 2 is designed as a faceted ground solid body. The luminous element 2 consists of turbid glass. This is represented by the clouding means 4 shown schematically, which are distributed in the luminous body 2. Within the housing 3, a reflector 6 is further arranged, are deflected with the light emitted from the light source 5 in the lateral direction of light beams 8 at least partially in the longitudinal direction A of the filament 2, and thereby also can serve for illumination. The color of these light beams 8 which do not propagate through the luminous body 2 corresponds to the color of the light emitted by the light source 5,
    Between the luminous element 2 and the light source S, an optical element 11 is arranged, into which the majority of the light rays emitted by the light source 5 enters and 01/10 2010 FR 10:04 [SE / EM NR 5713] @ 014 15/26 '/ 01/10/2010 09:02 + 43-512-583408 TDRGGLER & HOFINGER S. * I «► * * * ·· ** * ·« * · »·« * * t «· I» «I · * * »* Φ · · *« t * «· · * i« ·· «« * «• · | "I CI" · · · 10 which is at least partially transparent to light of the visible spectrum. The optical element 11 is in this embodiment an integral part of the luminous body 2 and formed as a cylindrical part, which is arranged below the upper housing edge of the housing 3 and may have the same degree of turbidity as the luminous body 2. In contrast, the luminous body 2 according to the invention is arranged above the upper housing edge of the housing 3, so that light beams emanating therefrom can reach an observer directly.
    In this embodiment, light of shorter wavelength is preferably scattered by the optical element 11 and does not reach the luminous body 2, as a result of which its proportion in the luminous body 2 and thus the color temperature is already reduced upon entry into the luminous element 2. The optical element 11 thus serves as a "pre-scatterer", the scattered light beams being deflected via the reflector 6 in the longitudinal direction A of the luminous body 2. Instead of the optical element 11, however, the light source can also adjoin the luminous body 2 directly.
    The light rays propagating in the optical element 11 and in the luminous body 2 are scattered at the opacifying means 4 serving as scattering centers, whereby mainly Rayleigh scattering occurs in which light of a higher frequency is scattered more strongly than light of a lower frequency. As a result, the higher-frequency component of the light emitted by the light source 5 during the propagation, in particular in the longitudinal direction A of the filament 2 and the optical element 11 due to multiple scattering is significantly reduced, while the low-frequency component of the light emitted by the light source 5 as it propagates through the optical Element 11 and the luminous body 2 is less affected by the opacifiers 4. Because of this, the spectral composition of a light beam along its direction of propagation - for example, in the longitudinal direction A - by the luminous body 2, if in this propagation direction sufficient material thickness and thus a sufficient number of serving as scattering turbidity opacifiers is present.
    The light beam 7a is scattered on the turbulence means 4 arranged in the pre-scattering optical element 11 and thus no longer enters the luminous body 2, as a result of which the color temperature of the light entering the luminous body 2 is reduced. Since the optical element 11 is disposed inside the housing 3, the scattered light beams 7a can not be directly viewed in the lateral direction. By the reflector 6, the light beams 7a are deflected in the longitudinal direction of the filament 2. Since the way 01/10 2010 FR 10:04 [SE / EM NR 5713] ®015 01/10/2010 09:02 + 43-512-583408 TORGGLER & HOFINGER P. 16/26
    11 of the light beam 7a in the optical element 11, which may be formed with respect to the turbidity as the luminous body 2, until the scattering is small, the light beam 7a substantially the color of the light beam 8 emitted from the light source 5, which is not in the optical element 11 has occurred.
    By contrast, the light beam 7b emerges from this after scattering approximately in the middle region of the luminous body 2. Along its propagation path in the luminous element 2, multiple high-frequency fractions of turbidity agents 4 have been scattered so that the light beam 7b has a different spectral composition than the light beam 7a and thus represents a different color visible to the human eye. The light beam 7c emerges from the luminous element 2 in the upper region of the luminous element 2 after scattering at a clouding agent 4. Due to the larger propagation path in the luminous body 2, this light beam has an even lower proportion of high-frequency light, so that it in turn has a different spectral composition and thus a different color than the light beams 7a and 7b. In the direction of propagation, for example in the longitudinal direction A of the luminous element 2, a color conversion of the luminous body 2 irradiated by the light source 5 is therefore visible to the human eye, since this is formed by the light rays 7a, 7b, 7c emerging from the luminous element 2.
    Fig. 2 shows the construction of the measuring device for measuring the correlated color order (CCT) and the color rendering index (CRi). For this measurement, e.g. a cylindrical filament 2 with a diameter of 20 mm and heights of 20, 40, 60 and 80 mm chosen. A light-emitting diode is arranged symmetrically on a cover surface of the cylindrical luminous body 2 and emits light beams into the luminous body 2. A detector 9 is arranged at a distance d of one meter from the top surface of the cylindrical filament 2 remote from the light source 5, the detector 9 being accurate is placed on the symmetry axis of the cylindrical filament 2. With the detector 9, light beams can thus be detected which are emitted by the light source 5 and propagate in the direction of the longitudinal direction A along the symmetry axis through the luminous body 2.
    3 a to 3 c show the results of the measuring arrangement according to FIG. 2 for determining the correlated color temperature for cylindrical luminous bodies 2 with heights of 20, 40, 60 and 80 mm and a diameter of 20 mm. This correlated color temperature is a measure of the color of the emerging from the top surface of the cylindrical Leuchtkorpers 2 01/10 2010 FR 10:04 [SE / EM NR 5713] ®016 01/10/2010 09:02 + 43-512-583408 TORGGLER & HOFINGER Ξ, 17/26 'h 12
    Light beams. A comparison with the correlated color temperature of the light emitted by the light source 5, without passing through the luminous body, gives a measure of the color conversion along the luminous element 2. The height of the cylindrical luminous body 2 is plotted on the abscissa axes. On the ordinate axes the measured correlated color temperature.
    In each case four different types of homogeneous opaque glass were used. A first embodiment of the opaque glass is a so-called "light white opal". The measuring points for this luminous element 2 are characterized by rhombuses. A second embodiment of the opaque glass is the so-called "white opal" whose measuring points are represented by squares. A third embodiment of the opaque glass is the so-called "white opal platinum white" whose measuring points are represented by triangles. A fourth embodiment of the opaque glass is the so-called "platinum white", whose measuring points are represented by an x. These embodiments of turbid glass are shown in Figures 3a to 3c with the same symbols.
    These embodiments differ by increasing turbidity, with the transparency of the filament 2 decreasing for visible spectrum light when the illumination device is not in operation. The lowest degree of turbidity is indicated by "light white opal" bordered by "white opal". on. The embodiment "white opal platinum white" has a greater degree of turbidity, while "platinum white" has the highest turbidity, and thus the highest concentration of opacifiers serving as scattering centers.
    The different degrees of turbidity can be infinitely converted into each other by a suitable choice of the parameters of the tempering process, as well as the amount and type of added to the base glass additives and adapted to the particular application. The tempering temperature is determined by the glass composition and opacifier chosen. The tempering time, ie the time during which the glass is exposed to the tempering temperature, is adjusted as a function of the desired degree of turbidity, with a greater turbidity setting with increasing tempering time. After a certain tempering time, which depends on the amount of opacifier added, saturation sets in, from which the degree of dryness can not be increased, even with a further increase in tempering time. 01/10 2010 FR 10:04 [SE / EM NO 5713] © 017 01/10/2010 09:02 + 43-512-583408 TORGGLERSHOFINGER ·· «·« · · · · · «♦ ··« * »« ········································································································································································································ the measurement according to FIG. 3a, a light-emitting diode was used whose correlated color temperature, which can be measured with the detector 9 when the luminous body 2 is removed from the measuring apparatus, is 5900 K. For those in the curves 10a, b, c, which connect the measuring points in each case one embodiment of the opaque glass for different heights of the cylindrical filament 2, it can be clearly seen that the correlated color temperature CCT measured by the detector 9 increases with increasing height H of the cylindrical filament 2 decreases. This applies to the last measuring point (at a height of the cylindrical luminous body 2 of SO mm) also for the connecting curve 10d of the measuring points of the "platinum white" opaque glass.
    The lower the correlated color temperature, the lower the proportion of high frequency light, i. Light of blue color has a higher correlated color temperature than light of red color. Thus, the higher the cylindrical luminous element 2 and the longer the path of the light propagating in the longitudinal direction of the luminous element 2 in the luminous element 2, the more the high-frequency component is scattered away and the lower the measured correlated color temperature CCT. This color conversion is the stronger, the higher the cylindrical filament, so the longer the propagation path of the light in the filament 2 is.
    FIG. 3b shows the same measurement as FIG. 3a, with the difference that the color temperature of the light-emitting diode 5 has a value of about 4340 K. The same effect of the decreasing correlated color temperature measured by the detector 9 with increasing height H of the cylindrical luminous element 2 occurs for all embodiments of the opaque glass up to the last measuring point of the curve 10d. FIG. 3 c shows the same measuring arrangement as FIGS. 3 a and 3 b, but with the difference that the correlated color temperature of the light-emitting diode used has a value of approximately 3120 K. Again, essentially the same effects occur.
    4 shows a measuring arrangement for measuring the correlated color temperature, wherein the detectors 9a, 9b, 9c are arranged at different angles around the illuminating body 2 consisting of opaque glass and can thereby detect light beams which have traveled various long propagation paths in the luminous body 2. The detectors 9a, 9b, 9c are arranged at a distance of 1 m from the luminous element 2.

    Haze level corresponds to the "white opal". FIGS. 3a to 3c. The LED itself has a correlated color temperature of 3100 K. The detector 9a is the same as in the measuring arrangement of Fig. 2, ie arranged in the extension of the longitudinal axis of the cylindrical filament 2 with respect to the luminous body 2 and can detect light rays 7 which have erroneously spread in the longitudinal direction filament 2. Compared to the output color temperature of the light emitting diode is carried out by the scattering along the entire length of the cylindrical filament 2, a strong color conversion, since a large proportion of high-frequency light was scattered away. The value of the correlated color temperature measured by the detector 9a is 2200 K.
    The detector 9b is inclined by 45 ° with respect to the longitudinal axis of the cylindrical filament 2. arranged offset, and can therefore detect light rays 7 ', which have covered a smaller path in the luminous body 2 than the light beams 7. Accordingly, a lower proportion of high-frequency light was scattered away, so that the light beams 7 'have a higher proportion of low-frequency light and thus a higher correlated color temperature and thus a different color than the light beams 7, this color has a higher Biauanteil. The value of the correlated color temperature measured by the detector 9b is 2200 K.
    The detector 9c is offset with respect to the longitudinal axis of the cylindrical filament 2 by a further 45 ° and thus arranged perpendicular to the longitudinal axis of the cylindrical filament 2, and can therefore light rays 1 " detect that have traveled an even smaller path in the luminous body 2 than the light rays T. Accordingly, an even lower proportion of high-frequency light was scattered away, so that the light beams 7 "have an even higher proportion of low-frequency light and thus an even higher correlated color temperature than the light beams 7 '. The color of the light rays 7 "thus has an even higher proportion of blue color. The value of the correlated color temperature measured by the detector 9b is 3100 K.
    The lighting device 1 according to the invention thus also allows illumination in which the color of the angle at which the luminous body 2 is considered in operation of the lighting device 1, whereby a special aesthetic impression is generated.
