Description

Scheinwerfer für FahrzeugeHeadlights for vehicles

Die Neuerung bezieht sich auf einen Scheinwerfer für Fahrzeuge mit einer Kunststoff-Streuscheibe. The innovation relates to a headlight for vehicles with a plastic lens.

Im Fahrbetrieb kann sich an der Streuscheibe eine elektrostatische Aufladung bilden. Durch die Aufladung werden Schmutzpartikel angezogen, die den Transmissionsgrad der Streuscheibe verringern. Zusätzlich kann es zu Entladungserscheinungen kommen, die die Schädigung elektrischer Bauteile im Fahrzeug nach sich ziehen kann.An electrostatic charge can build up on the lens when driving. The charge attracts dirt particles, which reduce the degree of transmission of the lens. Discharge phenomena can also occur, which can damage electrical components in the vehicle.

Der Neuerung liegt die Aufgabe zugrunde, einen Scheinwerfer der eingangs genannten Art zu schaffen, bei dem die Gefahr elektrostatischer Aufladungen beseitigt ist.The innovation is based on the task of creating a headlight of the type mentioned above in which the risk of electrostatic charges is eliminated.

Die Neuerung löst diese Aufgabe durch die Merkmale des Anspruchs 1.The innovation solves this problem by the features of claim 1.

2020

Durch die elektrische Verbindung zwischen der Streuscheibe und der Fahrzeugmasse können ggf. auftretende elektrische Ladungen abfließen. Die Gefahr einer Aufladung ist damit beseitigt. Damit wird der Transmissionsgrad der Streuscheibe nicht beeinträchtigt und elektronische Bauteile des Fahrzeugs vor den Folgen elektrostatischer Entladungen geschützt.The electrical connection between the lens and the vehicle ground allows any electrical charges to flow away. This eliminates the risk of charging. This means that the degree of transmission of the lens is not impaired and the vehicle's electronic components are protected from the consequences of electrostatic discharges.

Die elektrische Verbindung zwischen der Streuscheibe und der Fahrzeugmasse kann auf unterschiedliche Weise gestaltet sein. Sie kann in Form eines Drahtleiters realisiert sein, der mit der Streuscheibe und der Fahrzeugmasse elektrisch kontaktiert ist. Er kann auch eine Kontaktplatte sein, die mit der Innen- und/oder der Außenseite der Streuscheibe kontaktgebend verbunden ist. Besonders vorteilhaft istThe electrical connection between the lens and the vehicle ground can be designed in different ways. It can be implemented in the form of a wire conductor that is electrically connected to the lens and the vehicle ground. It can also be a contact plate that is connected to the inside and/or outside of the lens. It is particularly advantageous

die Ausführungsform, die in Anspruch 2 angegeben ist. Dadurch entfallen gesonderte Mittel zur Kontaktierung der Streuscheibe.the embodiment specified in claim 2. This eliminates the need for separate means for contacting the diffuser.

Anhand der Zeichnung ist die Neuerung dargestellt. In der einzigen Figur ist ausschnittsweise und im Schnitt ein Scheinwerfer gemäß der Neuerung dargestellt. Der nicht im einzelnen gezeigte Scheinwerfer besitzt eine Streuscheibe 1, die in einem Rahmen 2 gehalten ist. Der Rahmen ist mit der Fahrzeugmasse elektrisch verbunden (nicht dargestellt). Zur Fixierung der Streuscheibe 1 im Rahmen 2 dient ein Kleber 3, der in einem Aufnahmeprofil des Rahmens 2 sitzt und der nach seiner Aushärtung die Streuscheibe 1 fixiert.The innovation is shown in the drawing. The only figure shows a detail and a cross-section of a headlight according to the innovation. The headlight, which is not shown in detail, has a lens 1 which is held in a frame 2. The frame is electrically connected to the vehicle ground (not shown). An adhesive 3 is used to fix the lens 1 in the frame 2. This adhesive sits in a receiving profile of the frame 2 and fixes the lens 1 after it has hardened.

Der Kleber ist elektrisch leitfähig. Dadurch ergibt sich eine elektrische Verbindung zwischen der Innen- und der Außenseite der Streuscheibe 1 über den Rahmen 2 zur Fahrzeugmasse. Dadurch werden ggf. auftretenden elektrische Ladungen unmittelbar zur Fahrzeugmasse abgeführt. Die Streuscheibe befindet sich damit stets auf Massepotential. Elektrostatische Aufladungen können nicht mehr auftreten.The adhesive is electrically conductive. This creates an electrical connection between the inside and outside of the lens 1 via the frame 2 to the vehicle ground. This means that any electrical charges that may occur are immediately conducted to the vehicle ground. The lens is therefore always at ground potential. Electrostatic charges can no longer occur.
