Description
Lampenreflektor. Die Erfindung bezieht sich auf Lampenreflektoren, welche aus verschiedenen Spiegelteilen zusammengesetzt sind, insbesondere zur Verwendung für Straßenfahrzeuge. Die Erfindung bezweckt, eine gleichmäßige Verteilung der Lichtstrahlen über den zu beleuchtenden Querschnitt zu erzielen und gleichzeitig das störende Blenden zu vermeiden. Zu diesem Zweck ist der obere Teil des Reflektors als Teil einer Kegelfläche ausgebildet, während der untere Teil zwei oder mehr aneinanderschließende, vorzugsweise flache und etwa dreieckige Flächen bildet. Die Kegelfläche kann auch in der Längsrichtung nach außen gekrümmt ausgeführt werden.Lamp reflector. The invention relates to lamp reflectors, which are composed of different mirror parts, especially for use for road vehicles. The invention aims at a uniform distribution of the light rays to be achieved via the cross-section to be illuminated and at the same time the disruptive Avoid glare. To this end, the upper part of the reflector is part of it a conical surface, while the lower part has two or more adjoining, preferably flat and approximately triangular surfaces. The conical surface can also are designed to be curved outward in the longitudinal direction.
Die Zeichnung zeigt zwei Ausführungsformen der Erfindung, und zwar ist Abb. i eine Vorderansicht eines Reflektors, dessen obere Hälfte in der Querrichtung gekrümmt und in der Längsrichtung gerade ausgebildet ist.The drawing shows two embodiments of the invention, namely Fig. i is a front view of a reflector with its upper half in the transverse direction is curved and straight in the longitudinal direction.
Abb. 2 ist ein Längsschnitt in Richtung der Linie x-x durch Abb. i.Fig. 2 is a longitudinal section in the direction of the line x-x through Fig. I.
Abb. 3 ist eine schaubildliche Darstellung einer abgeänderten Ausführungsform, bei welcher die obere Hälfte der Reflektorfläche nach außen und in der Längsrichtung gekrümmt ausgeführt ist.Fig. 3 is a perspective view of a modified embodiment, in which the upper half of the reflector surface outwards and in the longitudinal direction is performed curved.
Abb. q. ist ein Längsschnitt in Richtung der Linie y-y in Abb. 2.Fig.q. is a longitudinal section in the direction of the line y-y in fig.
Bei der in Abb. i und 2 dargestellten Ausführungsform ist die obere Hälfte a der reflektierenden Fläche ein halber Kegel mit halbkreisförmigem Querschnitt, und die untere Hälfte besteht aus zwei aneinanderschließen den, vorzugsweise flachen, dreieckigen Flächen b und c. Die zusammentreffenden Spitzen der Dreiecke und des halben Kegels sind weggeschnitten, so daß innen an dem Reflektor eine Öffnung entsteht, durch welche die elektrischen Leitungsdrähte o. dgl. hindurchgehen können.In the embodiment shown in Fig. I and 2, the upper Half a of the reflecting surface is a half cone with a semicircular cross-section, and the lower half consists of two adjoining, preferably flat, triangular faces b and c. The meeting points of the triangles and the half cone are cut away so that an opening is created on the inside of the reflector, through which the electrical lead wires o. The like. Can pass.
Der Reflektor besitzt einen vorderen Flansch d, durch den er an dem Rahmen oder dem Gehäuse der Lampe befestigt wird.The reflector has a front flange d through which it is attached to the Frame or the housing of the lamp is attached.
Bei der in Abb. 3 und q. dargestellten Ausführungsform ist die obere Hälfte e der reflektierenden Fläche in der Längsrichtung nach außen gekrümmt, die untere Hälfte ist aus zwei aneinanderschließenden, im wesentlichen flachen und dreieckigen Flächen f und j gebildet.With the in Fig. 3 and q. illustrated embodiment is the upper one Half e of the reflective surface curved outward in the longitudinal direction, the lower half is made up of two adjoining, essentially flat and triangular Areas f and j are formed.
Der Reflektor gemäß der Erfindung kann an bereits vorhandenen Lampen angebracht werden, er kann aber auch bei der Neuherstellung von Lampen aus einem Stück mit der Lampe angefertigt werden.The reflector according to the invention can be used on existing lamps be attached, but it can also be used in the manufacture of new lamps from a Piece to be made with the lamp.
