Es wird ein Scheinwerfer oder eine Leuchte in Rechteckform für Fahrzeuge vorgeschlagen,, dessen Kunststoffreflekvor die beiden achsparallelen, optisch unwirksamen Abschnitte ausgespart hat und dessen zur Horizontalmittelebene des Scheinwerfers symmetrischer Lampenträger zwei Lappen aufweist, welche den der Strahlungswärme der Glühlampe ausgesetzten kritischen Bereich der beiden achsparallelen Abschnitte des Gehäuses abschirmen.It becomes a spotlight or a lamp in a rectangular shape proposed for vehicles, whose Kunststoffreflekvor the has left out two axially parallel, optically ineffective sections and its to the horizontal center plane of the headlight symmetrical lamp holder has two lobes which are exposed to the radiant heat of the incandescent lamp Shield the critical area of the two axially parallel sections of the housing.

Scheinwerfer und Leuchten in Rechteckform, die zusätzlich an der Karosserie oder an der Stoßstange anzubringen sind, haben eine verhältnismäßig niedrige Bauhöhe. Deren Gehäuse und zumeist auch deren Reflektoren bestehen dabei aus Kunststoffen mit jeweils entsprechender Temperaturbeständigkeit. Insbesondere bei Reflektoren aus Kunststoff sind die achsparallelen Abschnitte aus fertigungstechnischen und optiscuen Gründen zumeist überwiegende ausgespart , so daß die Strahlen der Glühlampe in diesen beiden ausgesparten Bereichen direkt auf die Innenseite der beiden anliegenden Gehäuseabschnicte fallen. Da der für das Gehäuse verwendete Kunststoff gegenüber dem des Reflektors aus Kostengründen eine niedrigere Wärmeformbeständigkeit aufweist, sind die der Glühlampe nächstliegenden Gehäuseabschnitte temperaturmäßig noch oder sogar überbelastet. Dies kann zu einer Deformation oder Zerstörung des Gehäuses führen.Headlights and lights in rectangular shape, which in addition are to be attached to the body or to the bumper, have a relatively low overall height. Their housing and mostly their reflectors are made of plastics, each with a corresponding temperature resistance. In the case of reflectors made of plastic, in particular, the axially parallel sections are made of manufacturing technology and optiscuen reasons mostly spared, so that the rays of the incandescent lamp in these both recessed areas fall directly onto the inside of the two adjacent housing sections. Since the For cost reasons, the plastic used for the housing has a lower heat resistance than that of the reflector has, the housing sections closest to the incandescent lamp are still or in terms of temperature even overloaded. This can lead to deformation or destruction of the housing.
Mit dem Scheinwerfer nach der Neuerung wird das im vorerwähnten Stand der Technik erörterte Problem im wesentlichen mit einfachen Mitteln gelöst. Der Neuerung liegt 3er Gedanke zugrunde, den masseführenden Lampenträger gleichzeitig als Schirm zu verwenden. Hierdurch wird die direkte Wärmeeins trQ.hlung auf den oberen und unteren Gehäuseabschnitt abgeschirmt, so daß zum «inen die niedrige Bauform beibehalten werden kann und zum andern weiterhin Kunststoffe mit niedriger Wärmefornbeständigkeit für das Gehäuse verwendbar sind.With the headlight according to the innovation, the problem discussed in the aforementioned prior art is essentially solved with simple means. The innovation is based on the idea of 3 to use the mass-carrying lamp holder as a screen at the same time. Thereby, the direct heat one is Q tr .hlung on the upper and lower housing portion shielded so as to "inen the low profile can be maintained and, secondly, further plastics can be used with low Wärmefornbeständigkeit for the housing.

Die Neuerung wird im folgenden anhand schematischer Zeichnungen näher erläutert. Fig. 1 ist ein Vertikalschnitt einer Nebelschlußleuchte, und Fig. 2 ist die Frontansicht des Lampenträgers. Die recheckförmige Nebelschlußleuchte in Fig. 1 besteht im wesentlichen aus einem Gehäuse 10 aus Kunststoff, einer davor gesetzten lichttechnisch v/irksamen Abdeckscheibe 11, einem am Gehäuse 10 befestigten Reflektor 12 und einem metallenen Lampenträger 13 mit eingesetzter Glühlampe Ik. Ein nur abschnittsweise dargestellter Bügel 15 sichert über eine Schraube 16 die Leuchte in ihrer Funktionslage,unc dessen nicht gezeichneter Abschnitt ist an der Karosserie oder der Stoßstange befestigt.The innovation is explained in more detail below with reference to schematic drawings. Fig. 1 is a vertical section of a rear fog lamp, and Fig. 2 is the front view of the lamp holder. The rectangular rear fog light in Fig. 1 consists essentially of a housing 10 made of plastic, a light technically v / ineffective cover plate 11 placed in front of it, a reflector 12 attached to the housing 10 and a metal lamp holder 13 with an inserted incandescent lamp Ik. A bracket 15, shown only in sections, secures the lamp in its functional position via a screw 16, and its section (not shown) is attached to the body or the bumper.
Der aus hochhitzebeständxgem Kunststoff hergestellte Reflektor 12 hat einen paraboloiden Teil 17 mit einem die Glühlampe Ik aufnehmenden Durchbruch 18 und zwei zur optischen Achse 20 parallelen Rippen 19· Mithin tritt der Lichtstrahl 21 und die in Richtung Abdeckscheibe 11 nach unten und oben fallenden Lichtstrahlen in den Innenraumteil 22.The reflector 12 made of hochhitzebeständxgem plastic has a parabolic part 17 with an opening 18 that accommodates the incandescent lamp Ik and two ribs 19 parallel to the optical axis 20 22nd

I bezüglich der vertikalen und horizontalen Hittelebene I 23, 2k symmetrisch ausgebildet. Sein I-iittelabschnitt 25 ■ f< nimmt den Lampensockel nasseführend auf, und eine Polzunge 26 drückt gegen den Polkontakt der Glühlampe 14. Zwei Öffnungen 27 dienen für die Befestigung mittels der Schraube Io bzw. zur Lagefixierung über einen Nocken 28 des Gehäuses 10.I formed symmetrically with respect to the vertical and horizontal central plane I 23, 2k . Its middle section 25 f <receives the lamp base in a wet-guiding manner, and a pole tongue 26 presses against the pole contact of the incandescent lamp 14.

Der Lampenträge 13 hat zwei Lappen 29> die im funktionsgemäßen Zustand an der Innenseite der beiden achsparallelen Abschnitte 30 des Gehäuses 10 anliegen, wobei die Endabschnitte 31 in Richtung optischer Achse 20 abgewinkelt sind. Die beiden Lappen 29 schirmen folglich den der Strahlungswärme der Glühlampe 1*1 ausgesetzten kritischen Bereich der beiden achsparallelen Abschnitte des Gehäuses 10 ab.The lamp holder 13 has two tabs 29> which, in the functional state, rest against the inside of the two axially parallel sections 30 of the housing 10, the end sections 31 are angled in the direction of the optical axis 20. The two flaps 29 consequently shield the radiant heat The critical area of the 1 * 1 incandescent lamp exposed two axially parallel sections of the housing 10.
