Beschreibung description
Die Erfindung betrifft eine Leuchte nach dem Oberbegriff des Schutzanspruchs 1. The invention relates to a lamp according to the preamble of claim 1.
Derartige Leuchten sind häufig so montiert, dass die sehr hellen, nahezu punktförmigen Halogenlampen den Benutzer blenden. Such lights are often mounted so that the very bright, almost point-shaped halogen lamps dazzle the user.
Der Erfindung liegt die Aufgabe zugrunde, die Blendfreiheit derartiger Leuchten zu verbessern. The invention has for its object to improve the glare-free of such lights.
Diese Aufgabe wird erfindungsgemäss durch das kennzeichnende Merkmal des Schutzanspruchs 1 gelöst. According to the invention, this object is achieved by the characterizing feature of the protection claim 1.
Es sind zwar langgestreckte Leuchten mit Blendschutzrastern grundsätzlich seit langem bekannt. Offensichtlich wurde es aber nicht für möglich gehalten, eine in einem zylindrischen Leuchtengehäuse angeordnete punktförmige Halogenlampe ohne Beeinträchtigung der Lichtwirkung, blendfrei zu machen. Es hat sich herausgestellt, dass die erfin-dungsgemässe Massnahme in einem zylindrischen Leuchtengehäuse diese Aufgabe ohne Beeinträchtigung der Beleuchtungswirkung einwandfrei löst. Elongated luminaires with anti-glare screens have basically been known for a long time. Obviously, however, it was not considered possible to make a point-shaped halogen lamp in a cylindrical luminaire housing glare-free without impairing the lighting effect. It has been found that the measure according to the invention in a cylindrical luminaire housing solves this problem without impairing the lighting effect.
Ein äusseres Schutzglas dient dem mechanischen Schutz des Rasters und auch des Leuchteninneren. An outer protective glass serves to mechanically protect the grid and also the interior of the luminaire.
Die Einspannung des Rasters zwischen zwei Glasscheiben gemäss den Ansprüchen 1 und 2 erhöht die Stabilität der Anordnung. Die innere Glasscheibe verhindert zudem eine zu starke Aufheizung der äusseren Glasscheibe. The clamping of the grid between two glass panes according to claims 1 and 2 increases the stability of the arrangement. The inner glass pane also prevents the outer glass pane from overheating.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 3 bis 5 unter Schutz gestellt. Further advantageous embodiments of the invention are protected in claims 3 to 5.
Anhand der Figuren werden zwei Ausführungsbeispiele der erfindungsgemässen Leuchte näher erläutert. Es zeigen Two exemplary embodiments of the luminaire according to the invention are explained in more detail with reference to the figures. Show it
Fig. 1 eine Aussenansicht in Axialrichtung des zylindrischen Leuchtengehäuses, wobei die linke und rechte Hälfte der Figur unterschiedliche Ausführungsformen darstellen, und Fig. 1 is an external view in the axial direction of the cylindrical lamp housing, the left and right half of the figure showing different embodiments, and
Fig. 2 einen Schnitt durch die beiden Ausführungsformen längs der Linie II-II in Fig. 1. FIG. 2 shows a section through the two embodiments along the line II-II in FIG. 1.
Bei beiden Ausführungsformen sind für gleiche oder entsprechende Teile gleiche Bezugszeichen verwendet. In both embodiments, the same reference numerals are used for the same or corresponding parts.
Bei der in den linken Hälften der Fig. 1 und 2 dargestellten Ausführungsform ist in einem im wesentlichen zylindrischen Leuchtengehäuse 10 eine nahezu punktförmige Halogeniampe 12 zentrisch angeordnet, die von einem Reflektor 14 in ihrer Lage gehalten wird. Der Reflektor 14 ist mittels Montageteilen 16 sowie zweier Sicherungsringe 18 am Leuchtengehäuse 10 festgelegt. Im Abstand vor der Halogenlampe 12 ist ein den ganzen Querschnitt des Leuchtengehäuses 10 ausfüllendes Blendschutzraster 20 mit quadratischem Rastermuster angeordnet. Das Blendschutzraster 20 ist zwischen einer inneren Glasscheibe 22 und einem äusseren Schutzglas 24 gehalten, wobei die innere Glasscheibe 22 von einem Sicherungsring 26 und das äussere Schutzglas (24) durch einen auf das äussere Ende 28 des Leuchtengehäuses 10 aufgesetzten Fassungsring 30 festgelegt ist. Zur wasserdichten In the embodiment shown in the left halves of FIGS. 1 and 2, an almost point-shaped halogen lamp 12 is arranged centrally in an essentially cylindrical lamp housing 10 and is held in position by a reflector 14. The reflector 14 is fixed on the lamp housing 10 by means of mounting parts 16 and two retaining rings 18. At a distance from the halogen lamp 12 is a glare protection grid 20 with a square grid pattern that fills the entire cross section of the lamp housing 10. The anti-glare grid 20 is held between an inner glass pane 22 and an outer protective glass 24, the inner glass pane 22 being fixed by a retaining ring 26 and the outer protective glass (24) by a frame ring 30 placed on the outer end 28 of the lamp housing 10. For waterproof
Abdichtung ist zwischen den Fassungsring 30, das Leuchtengehäuse 10 und das äussere Schutzglas 24 ein Dichtungsring 32 eingefügt. Der Fassungsring 30 ist mittels Schrauben 34 am Leuchtengehäuse 10 festgelegt. Sealing is inserted between the mounting ring 30, the lamp housing 10 and the outer protective glass 24, a sealing ring 32. The mounting ring 30 is fixed by means of screws 34 on the lamp housing 10.
Bei der in den rechten Hälften der Fig. 1 und 2 dargestellten Ausführungsform sind die innere Glasscheibe 22, der Fassungsring 30 und die Dichtung 32 weggelassen. An die Stelle der inneren Glasscheibe 22 tritt der Sicherungsring 26. In the embodiment shown in the right halves of FIGS. 1 and 2, the inner glass pane 22, the frame ring 30 and the seal 32 are omitted. The retaining ring 26 takes the place of the inner glass pane 22.
Im Blendschutzraster 20 ist bei dieser Ausführungsform eine der Halogenlampe 12 gegenüberliegende Blendkappe 38 mittig angebracht, durch die eine mögliche Blendung zusätzlich verringert wird. In this embodiment, a glare cap 38 opposite the halogen lamp 12 is mounted in the center of the glare protection grid 20, which additionally reduces possible glare.
