Description Lighting device, in particular a flush-marker light with spatially orientated light distribution The invention relates to a lighting device, in particular a flush-marker light with spatially orientated light distribution, for airport runways and taxiways, which has, in a housing which can be run over, at least one reflector lamp for generating light and at least one lens or a prism acting like a lens for guiding the light exit.
A lighting device corresponding to the above is known from DE 690 17 682 T2. For a portion of the light emitted by the lamp, this known lighting device has in the interior a reflecting mirror which disadvan-tageously constitutes a separate part which has to be mounted and adjusted individually.
It is the object of the invention to specify a lighting device, in particular a flush-marker light with spatially orientated light distribution for airport runways and taxiways which, by contrast, can be designed to be simpler, more cost-effective and lower.
Moreover, an embodiment as a flush-marker light emitting on both sides or radiating omnidirectionally is also to be possible.
The object is achieved by virtue of the fact that a part of the lens surface or prism surface on the lamp side has a coating having reflecting properties.
As a result of this advantageously simple embodiment, a component which is to be separately mounted and adjusted is eliminated, and the overall volume of the lighting device can advantageously be reduced.
One embodiment of the invention provides that the coating is constructed to totally reflect the light of the reflector lamp. Reflecting coatings are not necessarily constructed to be CA 022~981 1998-11-20 , totally reflecting; it can also prove to be advantageous for specific applications if the reflecting layer is only partially reflecting, for example if the light is to be emitted in bright and dark zones. A totally reflecting coating according to the invention is, however, advantageous for emitting light with a particularly high intensity.
In a further embodiment of the invention, it is provided that the coating is composed of metal, in particular aluminum, for example in a vapor-deposited finish. The result is a reflecting layer having particularly good long-term use characteristics. It is also possible to use another metal, for example a silver alloy, instead of aluminum. However, from the point of view of cost aluminum is the most favorable.
It is furthermore provided that the direction in which the light of the lamp is reflected points into the reflector interior. Renewed emission of the reflected portion of the light in a simple way is thereby ensured.
The lens or the prism can be constructed differently using the principle of retroreflecting a portion of the light emitted by the lamp in the reflector of the lamp. It is possible, for example, in this case for the lens or the prism to have individual surface elements which are geometrically separated from one another and cooperate optically in an active fashion. It is thereby possible, for example, for the lens or the prism to be constructed so as to generate a belt-lens effect. This produces a construction which is particularly suitable for a flush-marker light at airports which may have particularly favorable emission characteristics.
The construction of the lighting device as an omnidirectional radiator is also possible. A
particularly favorable illumination of the surface can be achieved thereby, in particular for instances of .. .. . ..... . ~

but also for traffic routes, footpaths etc.
Particularly for the use of the lighting device according to the invention as a runway end light or as a stop bar light, it is provided that the lens or the prism has a red, in particular dichroic, coating, preferably at least in the region which is constructed to be non-reflecting. The result is an advantageous, compact construction of a flush-marker light for the abovementioned applications which emits at high intensity.
Of course, the lighting device according to the invention is suitable not only for emitting white or red light. Blue, green or yellow light, as well, can likewise advantageously be emitted. In this case, color can be generated in all known ways.
The invention is explained in more detail with the aid of drawings from which, as well as from the subclaims, further details also essential to the invention can be gathered, and in which:
Figure 1 shows the beam path in the case of a reflecting layer on a prism, Figure 2 shows the beam path in a lighting device emitting in several directions, Figure 3 shows an enlarged representation of the region III in Figure 2, Figure 4 shows a side view of an emitting prism having a filter layer with partial cover by a reflecting layer, Figure 5 shows a perspective representation of a prism having an angled-off reflector surface, Figure 6 shows a section through a flush-marker light of particularly low construction which operates using the beam guidance according to the invention, and Figure 7 shows a plan view of a flush-marker light in accordance with Figure 6.
, . ~ ... , . , . . . . ,, _ CA 022~981 1998-11-20 ~.
In Figure 1, 1 denotes an emitting prism having a stop collar 2. A layer 3, a reflecting one in the example, is arranged on the lamp side of the prism 1.
This layer is, for example, a vapor-deposited one. Such a layer can, however, also be sprayed on or bonded on.
The lamp with the reflector 4 and the filament 6 generates light which is reflected at least partially in accordance with the illustrated beams 5 by the reflecting layer 3, re-reflected by the reflector 4 and emitted as a directed light beam 7.
In Figure 2, 8 denotes an optically active body having prismatic surfaces, or similar, which advantageously emits in several directions. The principle according to the invention is implemented by applying reflecting layers 9 and 10, which either reflect the beams 11 into the lamp 12 having the filament 13, or deflect them in such a way that they advantageously emerge directly from the illuminating device as directed beams 20 or, after passing the reflector 12 again, as beams 21. As may be seen in Figure 3, the reflecting layer 9 is advantageously divided and exposes an exit diaphragm 23. The upper part serves in this case as reflecting surface for the light 11. The reflecting layer 10 can optionally also be constructed in its upper part to retroreflect directly by means of optically active surfaces (stages), and in its lower part, as in the first-named embodiment, to emit in accordance with the law of "angle of incidence = angle of reflection", that is to say singly coated, for example.
In Figure 4, 14 denotes a prism, seen from the side, having the collar 15. On the entrance site, the prism 14 has, for example, a red, dichroic layer 16 on the outside of which a reflecting layer 17 is arranged.
On the entrance side, the prism 14 is advantageously switched off to be simply flat.
In Figure 5, 18 denotes the prism and 19 the reflecting layer, 22 denoting a bend in the entrance , . CA 02255981 1998-11-20 GR 96 P 3374 P - 4a -surface. On the inside, such prisms do not, CA 022~981 1998-11-20 advantageously as the case may be, have a flat entrance surface, as represented in Figure 1 and Figure 4, for the light. In order to be able to fashion the optical properties yet more favorably, a flat or lens-shaped entrance surface is joined to an angled-off reflecting surface, for example. The bend is relatively slight in this case, for example below 1~. The result is a lens-prism combination having optimum properties for the respective task of emission, which can advantageously be mounted in the simple way which is customary.
In Figure 6, 24 denotes the cover of a flush-marker light which is of particularly low construction and which snow-clearing vehicles can roll over effectively. 25 denotes the housing of the flush-marker light, which has a cable bushing 32. The lamp 29, emitting through the prism 26, is arranged with the reflector 28 on a plate 31 in a vibration-damped fashion. The optical axis of the lamp 29 extends, advantageously as the case may be, asymmetrically relative to the mechanical axis of the prism, and can, just like its angle of inclination, be modified, for example by means of special lamp mounts, depending on the specification. The beam path is visible from the arrows drawn in. Despite the fact that the light is emitted in accordance with airport specifications, the elevation 30 is only approximately 5-7 mm.
By way of example, Figure 7 shows the flush-marker light according to the invention - the principle according to the invention can be used to produce all flush-marker lights used at airports - in a 3-lamp, bidirectional finish seen from above. The light is emitted through the exit openings 35, 36 and 37, and is indicated by the arrows drawn in. The cover 33 is fastened to the lower part (not visible) by means of screws 34.
