    The invention relates to a sighting device, in particular reflex sight or telescopic sight, which has a lighting device for generating or illuminating a Ziel¬ mark, wherein the lighting device comprises a light guide of photoluminescent, in particular fluorescent material and a light guide coupled to the radioluminescent light source, wherein the Optical fiber is ausgebil¬det to take along at least a portion of its longitudinal extension Umge¬bungslicht and convert it into photoluminescent light, and winne the absorption spectrum of the photoluminescent material of the light guide and the emission spectrum of the radioluminescent light source in the visible range in each case by a spectral bandwidth and a mean wavelength cha ¬rakterisierbar are.
    Known sighting devices use ambient light (daylight) to produce a target mark, also called reticle, e.g. in the form of a crosshair, a Maßsta¬bes or a point to produce or illuminate. The ambient light is captured by means of a light collecting conductor and converted into fluorescent and / or phosphorescent light by a photoluminescent dye in the light collecting conductor.
    In order to obtain a target mark with sufficient luminosity even at night or at dusk, known sighting devices have a radioluminescent light source whose light is fed into the optical waveguide and likewise converted there into photoluminescent light.
    The photoluminescent light generated by the light guide can now be guided or reflected in the beam path of the sighting device. In other sighting devices, the photoluminescent light may comprise an already existing aiming marker illumination, e.g. Rear sight and / or grain.
    EP 0 830 559 B1 discloses a sighting device with a light collecting conductor and a Triga light coupled to the light collecting conductor as the radioluminescent light source.
    The disadvantage of such lighting devices is that due to unzu¬reichende light yield by the conversion of the light in fluorescence lights a radioluminescent light source of high light intensity must be selected. This not only increases the costs, but also the space required for larger Radiolicht¬ sources. A fundamental problem is that visible light to the human eye, e.g. In the green wavelength range, an excitation corresponding fluorescent dyes in the blue or violet range requires. The generation of excitation light of this initially dark color in sufficient measure would require a space-demanding (correspondingly large-sized light source) and complex (lossless as possible feed of the excitation light into the light guide ) Require construction. Especially with sighting devices, however, the available space is severely limited, so that this problem could not yet be solved satisfactorily.
    The object of the invention is therefore to eliminate these disadvantages and to provide a sighting device which provides a high luminosity for the target mark, both in daylight and at twilight and at night. The construction should be space-saving and cost-effective.
    This object is achieved with a sighting device of the type mentioned in that the mean wavelength of the emission spectrum of the radioluminescent light source is greater than the average wavelength of the absorption spectrum of the photoluminescent material of the light guide.
    As a result, light emitted by the radioluminescent light source is no longer used primarily for exciting the photoluminescent material in the optical waveguide. Instead, a high proportion of the light emitted by the radioluminescent light source is passed through the light guide, without its Wel¬lenlänge changes significantly in the light guide. Thereby, the light of the radioluminescent light source is used directly for the generation or illumination of the target.
    Accordingly, the average energy of the light emitted by the radioluminescent light source is less than the average energy of the absorption spectrum of the photoluminescent light guide.
    However, the ambient light collected by the light guide is still converted into photoluminescent light, in particular fluorescent light. Of course, phosphorescent dyes would also be conceivable in the light guide, which is why the term "photoluminescence" is used in the present application.
    A further effect of the invention is that the mean wavelength of the emission spectrum of the radioluminescent light source is now much closer to the central wavelength of the emission spectrum of the photoluminescent material of the light guide, so that at least adjacent or at least very similar shades can be obtained whose superposition already leads to a significant luminosity gain. In a preferred embodiment, the light emitted by the radioluminescent light source and the photoluminescent light of the light guide even have the same color, whereby the visibility of the target can be further increased. Usually, the absorption spectrum of the photoluminescent material of the light guide and the emission spectrum of the radioluminescent light source in the visible range are not limited to a single wavelength but can be described by a wavelength distribution. This is by a maximum or. characterized a maximum range, the side drops more or less strong. The wavelength distribution is characterized in each case by a spectral Bandbrei¬te and an average wavelength. The bandwidth depends on the lateral fall of the curve and corresponds to the width at half the height of the peak of the wavelength distribution. This width is also called full width at half maximum (FWHM). The mean wavelength in the visible range results from the formation of the mean value of the corresponding wavelength distribution.
    The radioluminescent light source is preferably a tritium light source. Gaseous tritium is enclosed in a capsule, in particular a glass tube. The capsule is coated with a phosphor. The radiation emitted by the radioactive tritium is converted by the phosphor into visible light of a certain wavelength range, e.g. green, blue or purple. The phosphor is also a fluorescent dye which can be selected according to the teachings of the invention (color).
    The light guide is preferably made of plastic, in particular polymethylmethacrylate (PMMA) or polystyrene (PS), and contains fluorescent and / or phosphorescent dyes. Depending on the desired color, different dyes are used. Thus, e.g. Green fluorescent light (~ 480nm to 560nm) can be obtained by Cu + - and AI3 + -doped zinc sulfide as Fluoreszenzfarb-. The selection of a corresponding dye can be made by the skilled person without further difficulties.
    Technical fluorescent dyes are e.g. from substances such as the very commonly used zinc sulfide and chemically similar compounds or oxides of rare earth metals. If these compounds are doped with so-called activators, different colors can be produced. As activators divalent and trivalent lanthanide cations are frequently used. For example, divalent europium cations generate blue light while the trivalent red light emit. Green light is produced, for example, by Cu + and Al3 + -doped zinc sulfide. At this point it should be noted that these dyes are given as examples only, but do not represent any limitation of the invention. Any dye formed according to the specifications of the invention and its Ausführungs¬ forms can be selected. This also presents no difficulties for the person skilled in the art.
    In a section of its longitudinal extent, the light guide is exposed to the ambient light (directly or indirectly). For example, the light guide runs on an outer side of the sighting device or sits behind a window through which ambient light can pass into the light guide. Also conceivable are light-conducting and / or light-deflecting and / or Lichtfokussiermittel that lead the ambient light to the light guide. The ambient light is usually recorded in the radial direction in the light guide.
    The term target can be understood to mean both a light pattern (for example directed into the beam path) and a mechanical target mark (for example, sight and / or grain). Type, shape, size and pattern are not subject to any restrictions here. The target (also called reticle) may e.g. a crosshair, a quantified or unsized scale, a target point or a target window.
    Preferably, the mean wavelength of the emission spectrum of the radioluminescent light source is at least 30 nm, preferably at least 50 nm, greater than the mean wavelength of the absorption spectrum of the photoluminescent material of the light guide. As a result, the spectra are shifted sufficiently relative to one another, which prevents a high proportion of the light emitted by the radio-luminescent light source from being absorbed by the dye in the light guide.
    The spectral bandwidth of the emission spectrum of the radio-luminescent light source and the spectral bandwidth of the absorption spectrum of the photoluminescent material of the optical waveguide are preferably at most 100 nm, preferably at most 80 nm. By this measure, which is achieved by appropriate selection of dyes as photoluminescent material, for example by Cu + and Al3 + -doped zinc sulfide in the case of green light, the individual spectra can be well separated so that the least possible overlap exists.
    The spectral bandwidth of the emission spectrum of the radioluminescent light source and the spectral bandwidth of the absorption spectrum of the photoluminescent material preferably do not overlap. This measure also causes a high proportion of the light emitted by the radioluminescent light source to be unaffected by the light guide, i. unchanged in its wavelength, passes through. The absorption ratio can thereby be kept small.
    Preferably, in the visible region at most 30%, preferably at most 20%, of the emission spectrum of the radioluminescent light source overlap with the absorption spectrum of the photoluminescent material of the light guide.
    Preferably, in the visible range at least 50%, preferably at least 70%, of the emission spectrum of the radioluminescent light source overlaps with the emission spectrum of the photoluminescent material of the light guide. This action causes the light of the radioluminescent light source and the photoluminescent light of the light guide to have at least similar hues adjacent in the spectrum, whereby the visibility of the target can be increased. Particularly preferred is that variant in which the light of the radioluminescent light source and the photoluminescent light of the light guide have the same color. So there are no color differences between day and night. In addition, the user seems much brighter to the target.
    The emission spectrum of the radioluminescent light source is preferably in the green and / or yellow wavelength range. The sensitivity of the human eye is greatest in the green wave region. Also, the photometric luminance and the radiometric radiance of green (i.e., in the green Wel¬lenbereich emitting) or green-yellow tritium light sources is much higher than those of blue or violet light sources of the same size. Since according to the invention the absorption spectrum of the light guide is attempted to be as close as possible and on the other hand to provide a clearly visible target for which green light is most suitable, a green radioluminescent light source represents a particularly preferred embodiment.
    The main advantage is that you can use green to yellow-green tritium light sources ("Triga lights"). The green and yellow-green tritium light sources are generally markedly brighter (in photometric terms for the eye and radiometric in terms of the number of photons) than the blue and orange and red. Thus, with the green to yellow-green tritium light sources, more light is lost addition than the other colors. Thus, with the inventive principle of equal radioactivity (GBq tritium), more recognizable light can be generated compared to the prior art. For the production of green fluorescent light (clearly visible to the eye) in the light guide, it would have to be excited with a blue tritium light source (very dark) with a corresponding fluorescent dye. When using green light sources (bright), orange or red fluorescent light (not easily visible to the eye) would be generated in the light guide with the corresponding fluorescent dye.
    The principle according to the invention differs now in that the effect of the photoluminescence excitation in the optical waveguide is kept as small as possible by the light emitted by the radioluminescent light source and that a possibly high proportion of the light emitted by the radioluminescent light source is uninfluenced, i. unchanged in wavelength, used for the target.
    It is thus particularly preferred to have a green or green-yellow tritium light source (bright) together with a green light guide, i. with a green photoluminescent dye (well visible from the eye). The principle can also be used for other colors. However, the efficiency advantage of green light is particularly high. The use of other efficient phosphors than green is of course included in the invention. In the presence of such an efficient fluorescent dye, the functional principle of the invention can also be applied to this color (e.g., yellow, red, orange, etc.).
    Preferably, the emission spectrum of the photoluminescent material of the optical waveguide is in the green wavelength range. Here, the same advantages as already mentioned above result, the superimposition of the light emerging in the light guide green light and fed by the Radioluminszent light Lich¬tes causes a very good visibility of the target.
    Preferably, the radioluminescent light source is disposed on an end face of the light guide, whereby light of the radioluminescent light source is coupled through the end face into the light guide. By such coupling, light losses can be efficiently avoided, especially since the light of the radioluminescent light source is to be conducted through the light guide as uninfluenced as possible (i.e., the absorption spectrum promptly).
    Preferably, the end face of the light guide is glued to the radioluminescent light source by means of a transparent adhesive. This prevents light losses and provides a mechanically stable solution. The adhesive used is preferably a so-called .reflection index matching adhesive. The refractive index is adjusted via the adhesive so that the light can pass through the boundary surfaces with minimal losses.
    Preferably, the radioluminescent light source has a longitudinal extension (i.e., it has elongated shape), which is transverse to the axis of the light guide in its Endbe¬reich. The light source thus protrudes beyond the end face. Thus, light losses can be kept low even with inaccurate positioning of the light source relative to the light guide.
    The end face of the light conductor facing the radioluminescent light source is preferably a polished surface, whereby the light enters without undesired reflections on the end face. It is preferably a highly polished surface.
    The sighting device preferably comprises a reversing prism arranged in the beam path, preferably a Schmidt-Pechan prism, and the end face of the light guide facing away from the radioluminescent light source is aligned with an especially circular opening in a mirrored plane surface of the reverse prism. Here, the target can be generated as a light pattern of high intensity.
    A preferred embodiment is characterized in that the end face of the light guide facing away from the radio-luminescent light source is a polished surface, which preferably faces a prism for coupling the light into a ray path of the sighting device. This prism may be the prevalent reversing prism but may also be e.g. only one (upstream) deflecting prism.
    Both ends of the light guide are polished in the optimal case. This increases the Lichtef¬fizienz. This can be further improved with a .reflection index matching adhesive. The polished surfaces at the ends of the light guide represent a preferred embodiment, but are not absolutely necessary for the realization of the inventive idea.
    The radioluminescent light source is preferably enveloped by a particularly opaque coating, wherein preferably the coating is a white color, particularly preferably a color pigmented with TiO 2. This increases the efficiency of the light source. Only in a limited area, which faces the light guide direkt¬, a light exit opening remains free of the opaque Beschich¬. The coating is a reflection layer that reflects the light generated by the radiolucent light source back to it.
    The coating is preferably applied to the surface of the radioluminescent light source. In an alternative embodiment, the coating is attached to the inside of a housing surrounding the radioluminescent light source.
    The radioluminescent light source and an end section of the light guide which borders on the radioluminescent light source are preferably surrounded by a housing in a form-fitting manner. This represents a compact, space-saving solution that provides the necessary mechanical stability of the connection between the light source and the light guide and ensures optimum protection against damage and contamination.
    Preferably, the housing is formed from two parts, wherein preferably the two parts are mutually pivotable or held together by means of a Schnappein¬richtung. This measure facilitates the insertion and assembly of the light source and the light guide, and the subsequent closing of the light source and the connection point between the light source and the light guide.
    Preferably, the housing has at least one opening, which leads from the outside to the An¬kopplungsstelle between the radioluminescent light source and the light guide, in particular for the introduction of an adhesive. Thus, the light guide and the light source can be precisely aligned and remain positioned before they are glued miteinander. The assembly is considerably simplified.
    Preferably, at least one screw in a screw thread is seated in the housing, through which the radioluminescent light source and / or an end section of the light guide adjacent to the ra-dioluminescent light source is / are clamped. This allows a simple and reliable fixation of the parts in the desired position.
    The radioluminescent light source and an end section of the light guide which borders on the radioluminescent light source are preferably surrounded by a shrink-fit tube, in particular T-shaped. This allows a space-saving and easy to be accomplished connection.
    The radioluminescent light source is preferably cast into a material together with an end section of the light guide which borders on the radio-luminescent light source. This also creates a reliable and durable connection that keeps out dirt and contamination.
    In the following, further preferred aspects are enumerated in a cursory manner, which can each be realized separately or together:
    The light guide consists of a green fluorescent plastic;
    At least on one end, the light guide is highly polished; By polishing the end faces of the light guide and the special coupling of the tritium light source and the light collection in the region of the tritium light source with the opa ken layer optimal energy utilization of tritium light for the imaging of the target in the (reflex) visor is achieved become;
    The light guide is aligned with an annular opening in a mirrored Planflä¬che a Schmidt-Pechan prism;
    On the opposite end, a tritium light source is coupled by means of radiation (reflection reflection index matching);
    The Triga-Light is enveloped with an opaque reflection layer until the beginning of the light guide; the optimal solution being a white opaque coating; but there are also other reflective layers such as silver or Verspiegelungen possible;
    The coupling of the tritium light source or the connection of the tritium light source to the light guide is followed by a section of the light guide via which the daylight can enter the light guide in the radial direction;
    The energy of the light emitted by the tritium light source should now be as small as possible the absorption energy of the dye in the light guide; i.e. the tritium light source should as far as possible not excite the fluorescent and / or phosphorescent substances in the light guide in order to avoid energy loss;
    The ambient or daylight, on the other hand, should stimulate these fluorescent and / or phosphorescent substances in order to enable imaging in the (reflex) sphere;
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    Furthermore, individual features or combinations of features from the different embodiments shown and described can also represent solutions that are inventive, inventive or inventive.
    The problem underlying the independent inventive solutions can be taken from the description. All statements on ranges of values in the description given herein are to be understood as including any and all subsections thereof, for example, the indication 1 to 10 should be understood as encompassing all subranges, starting from the lower bound 1 and the upper bound 10, i. all subregions begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1, or 5.5 to 10.
    Above all, the individual embodiments shown in the figures can form the subject of independent solutions according to the invention. The relevant objects and solutions according to the invention can be found in the detailed descriptions of these figures.
    For the sake of order, it should finally be pointed out that for a better understanding of the structure of the sighting device and the lighting device diesebzw. some of the components of which have been shown to be incomplete and / or enlarged and / or reduced in size.
    1 to 7 show a lighting device 2 for generating or illuminating a target mark in a sighting device 1. An example of a sighting device is shown purely schematically in FIG. In the beam path those optical elements are shown, which cooperate with the lighting device 2. Other (also existing elements) have been omitted for the sake of clarity.
    The light-emitting device 2 comprises a light guide 3 made of photoluminescent, in particular fluorescent, material and a light-emitting light source 7 coupled to the light guide 3. The light guide 3 is designed to record ambient light along at least one section 4 of its longitudinal extent and to convert it into photoluminescent light.
    The absorption spectrum 10 of the photoluminescent material of the light guide 3 and the emission spectrum 9 of the radioluminescent light source 7 in the visible region are essentially characterized by a spectral bandwidth (B) and an average wavelength (FIGS. 9 and 10). As can be seen from FIGS. 9 and 10, the mean wavelength of the emission spectrum 9 of the radioluminescent light source 7 is greater than the mean wavelength of the absorption spectrum 10 of the photoluminescent material of the light guide 3. The band width results from the .full width at half maximum '(FWHM) and the mean wavelength by forming the mean value of the wavelength distribution.
    In Fig. 9, the emission spectrum 9 of the radioluminescent light source 7 and the emission spectrum 11 of the photoluminescent material of the light guide 3 are spaced from each other (i.e., they do not overlap or only slightly).
    It is preferred if, as can also be seen from FIG. 10, the mean wavelength of the emission spectrum 9 of the radioluminescent light source 7 is greater than the mean wavelength of the absorption spectrum 10 of the photoluminescent material of the light guide 3 by at least 30 nm, preferably by at least 50 nm.
    In this case, the spectral bandwidth of the emission spectrum 9 of the radioluminescent light source 7 and the spectral bandwidth of the absorption spectrum 10 of the photoluminescent material of the light guide 3 are preferably at most 100 nm, preferably at most 80 nm.
    It is particularly preferred if, as can be seen from both FIGS. 9 and 10, the spectral bandwidth of the emission spectrum 9 of the radioluminescent light source 7 and the spectral bandwidth of the absorption spectrum 10 of the photoluminescent material of the light guide 3 do not overlap. That the Bandbrei¬tenbereiche the spectra 9 and 10 are completely outside of each other.
    It can also be seen that in the visible range at most 30%, preferably at most 20%, of the emission spectrum 9 of the radioluminescent light source 7 overlaps with the absorption spectrum 10 of the photoluminescent material of the optical waveguide 3.
    The particular embodiment of FIG. 10 shows (unlike FIG. 9) that the visible region overlaps at least 50%, preferably at least 70%, of the emission spectrum 9 of the radioluminescent light source 7 with the emission spectrum 11 of the photoluminescent material of the light guide 3.
    In this case, the emission spectrum 9 of the radioluminescent light source 7 lies in the green or in the green-yellow wavelength range and the emission spectrum 11 of the photoluminescent material of the optical waveguide 3 in the green wavelength range.
    The choice of the corresponding radioluminescent light sources and the associated light guide according to the specifications of the invention is not a difficulty for the expert. Light sources and light guides are available on the market in any embodiments.
    FIGS. 1 to 7 show that the radioluminescent light source 7 is arranged on an end face 6 of the light guide 3, whereby light of the radioluminescent light source 7 is coupled through the end face 6 into the light guide 3.
    The radioluminescent light source 7 may have a longitudinal extent which is transverse to the axis of the light guide 3 in its end region. The light source 7 and the end portion of the light guide 3 thus together form a T-shape.
    The radioluminescent light source 7 (also called "triga-light") does not necessarily have to be oblong. It is preferred that the contact surface of the radioluminescent light source 7 is larger than the entrance surface of the light guide. Square and round radioluminescent light sources would also be useful.
    The radioluminescent light source 7 is enveloped by an opaque coating 8, wherein preferably the coating 8 is a white color, particularly preferably a color pigmented with TiO 2. The radioluminescent light source 7 facing end face 6 of the light guide 3 is a polished surface. The front side 6 of the light guide 3 is glued to the radioluminescent light source 7 by means of a transparent adhesive.
    In the embodiment shown in Fig. 2, light source 7 and light guide 3 are positioned on a disposable jig and fixed by clips. The disposable teaching is poured in. As a result, a reliable connection between the light source 7 and the light guide 3 is obtained. It goes without saying that the radioluminescent light source 7, together with an end section of the light guide 3 bordering on the radioluminescent light source 7, could also be cast into a material without positioning means, such as the one-way jig.
    In the embodiment shown in FIG. 3, the radioluminescent light source 7 and an end section of the light guide 3 bordering the radioluminescent light source 7 are surrounded by a housing 13 in a substantially form-fitting manner. Openings for introducing light source 7 and light guide 3 are provided. The housing 13 has at least one further opening 14, which leads from outside to the coupling point between the radioluminescent light source 7 and the light guide 3, in particular for the introduction of an adhesive.
    A similar embodiment but with a different housing shape is shown in FIG. 4.
    In the embodiment shown in FIG. 5, the housing 13 is formed from two parts, which are joined or held together by means of a snap-action device 15.
    In the embodiment shown in FIG. 7, the two housing parts are pivotable relative to one another in order to move from an open position into a closed position.
    In the embodiment shown in Fig. 6 it can be seen that in the housing 13 at least one screw 16 is seated in a screw thread through which the radioluminescent light source 7 and / or an end portion of the light guide 3 bordering the radioluminescent light source 7 is / are clamped.
    In an alternative embodiment, the radioluminescent light source 7 and an end section of the light guide 3 which borders on the radioluminescent light source 7 are surrounded by a shrink-fit tube, which is in particular T-shaped.
    In all the above-described embodiments of the lighting device 2, it is preferable that the efficiency can be increased by attaching or providing a reflection layer (e.g., a white, silver, etc.) around the radioluminescent light source 7. The reflection layer could be an outer coating of the light source 7. Alternatively, the reflection layer may be formed on the inside of the housing 13 surrounding the light source 7, that is, the housing already has these reflective properties.
    Finally, FIG. 8 shows a sighting device 1, in particular in the form of a re-focussing sight or telescopic sight, which has a lighting device 2 for generating or illuminating a target mark. The representation is purely schematic and should only be one of many possibilities.
    The sighting device 1 from FIG. 8 comprises an objective 17, an eyepiece 18 and an inverted prism 12 arranged in the beam path 19, in the form of a Schmidt-Pechan prism, through which the light from the lighting device 2 is coupled into the beam path 19. The end face 5 of the light guide 3, which faces away from the radioluminescent light source 7, is aligned with a particularly circular opening in a mirrored plane surface of the reversing prism 12.
    It should be noted that any other suitable optical element could be used to introduce the light of the lighting device 2 into the beam path 19. As already mentioned at the outset, the invention can also be applied to sighting devices in which the lighting device 2 illuminates a mecha¬ nese target.
