Abstract

The indicator light has its colour produced by the colour of its reflector (10). The outer transparent cover (16) of the assembly has a gridwork comprising totally reflecting prisms (19) and lenses (18). An inner window (17) is located between the outer cover and the light-bulb and has lenses (20) to direct the light onto the lenses of the outer cover. External light incident on the totally-reflecting prisms (19) is reflected back outwards. The gridwork ensures that when the light is off, the colour of the indicator light is not visible. The outer cover may be replaced by a plane outer window with an extra window facing its inside surface. The extra window comprises a matrix of totally-reflecting prisms and holes. The holes take the place of the lenses in the original outer cover.

Description

Es zeigen Fig. 1 abschnittsweise in Axialschnitt das erste Ausführungsbeispiel mit Reflektor, eingesetzter Glühlampe und davor gesetzter Optik in vergrößertem Maßstab; Fig. 2 abschnittsweise das zweite Ausführungsbeispiel jedoch nur die Optik, ebenfalls in Axialschnitt und vergrößertem Maßstab; Fig. 3 ausschnittsweise den Raster in Blinkrichtung gemäß Pfeil II in Fig. 1 in noch vergrößertem Maßstab als die Fig. 1 und 2.DRAWING Two exemplary embodiments of the invention are shown in the drawing and explained in more detail in the following description. 1 shows the first exemplary embodiment with reflector inserted in sections in axial section Incandescent lamp and optics placed in front of it on an enlarged scale; Fig. 2 in sections the second embodiment, however, only the optics, also in axial section and enlarged scale; 3 shows a section of the grid in the blinking direction according to Arrow II in FIG. 1 on an even larger scale than FIGS. 1 and 2.

Beschreibung der Ausführungsbeispiele Fig. 1 zeigt von einer Blinkleuchte einen Reflektor 10 mit einer gelb eingefärbten Reflexionsschicht 11 und eine in deren Scheitelbereich eingesetzte Glühlampe 12, deren Glühwendel 13 im Brennpunkt des Reflektors 10 angeordnet ist, so daß das Signallichtbündel - versinnbildlich durch die drei Strahlen 14 - parallel zur optischen Achse 15 reflektiert wird.DESCRIPTION OF THE EXEMPLARY EMBODIMENTS FIG. 1 shows a flashing light a reflector 10 with a yellow-colored reflective layer 11 and one Incandescent lamp 12 inserted in the apex area, the incandescent filament 13 in the focal point of the reflector 10 is arranged so that the signal light beam - symbolically is reflected by the three rays 14 - parallel to the optical axis 15.

Eine Abdeckscheibe 16 aus farblosem Kunststoff hat an ihrer Innenseite einen Raster aus total reflektierenden Flächen 19 und Linsen 18 angeordnet, wobei die Linsen rechtwinklig zur optischen Achse 15 und optisch unwirksam sind. Die total reflektierenden Flächen 19 sind sogenannte Tripel, die das von außen einfallende Fremdlicht - versinnbildlich durch die Strahlen 21 bis 23 - nach außen reflektieren.A cover plate 16 made of colorless plastic has on its inside arranged a grid of totally reflective surfaces 19 and lenses 18, wherein the lenses are perpendicular to the optical axis 15 and optically ineffective. The total reflecting surfaces 19 are so-called triples, which are incident from outside External light - symbolized by the rays 21 to 23 - reflect outwards.

Eine Sammellinsenscheibe 17 aus ebenfalls farblosem Material hat an ihrer der Abdeckscheibe 16 zugewandten Seite Sammellinsen 20, wobei jede Linse derart angeordnet und bemessen ist, daß die parallel eintretenden Strahlen 14 gebündelt und auf die dahinterliegende planparallelen Linsen 8 gerichtet werden und optisch unbeeinflußt nach außen hindurchtreten.A converging lens disk 17 made of likewise colorless material has on its side facing the cover plate 16 convergent lenses 20, each lens in such a way is arranged and dimensioned so that the beams 14 entering parallel are focused and are directed to the plane-parallel lenses 8 lying behind and optically step through unaffected to the outside.

Das zweite Ausführungsbeispiel in Fig. 2 zeigt die Sammellinsenscheibe 17 mit den Sammellinsen 20, eine Rasterscheibe 24 und die Abdeckscheibe 26 mit optisch wirksamen Mitteln 25.
