Patentschrift
Aufgabe der Erfindung ist es, eine Bremsleuchte, insbesondere eine hochgesetzte dritte Bremsleuchte, eines Kraftfahrzeugs, mit mindestens einem Leuchtenkörper aus Kunststoff, in den ein Leuchtmittel, insbesondere ein LED-Chip, eingebettet ist, und mit einer Lichtscheibe, zu schaffen, die einfach und kostengünstig herstellbar ist.task The invention is a stop lamp, in particular a raised third brake light, of a motor vehicle, with at least one luminaire body made of plastic, in which a light source, in particular an LED chip, is embedded, and with a lens, to create that simple and cost-effective can be produced.
Die Aufgabe ist bei einer Bremsleuchte, insbesondere einer hochgesetzten dritten Bremsleuchte, eines Kraftfahrzeugs, mit mindestens einem Leuchtenkörper aus Kunststoff, in den ein Leuchtmittel, insbesondere ein LED-Chip, eingebettet ist, und mit einer Lichtscheibe, dadurch gelöst, dass der Leuchtenkörper mit dem eingebetteten Leuchtmittel und die Lichtscheibe von verschiedenen Komponenten eines Mehrkomponentenspritz gießteils aus einem thermoplastischen Kunststoff gebildet sind. Durch die Ausbildung der Bremsleuchte als Mehrkomponentenspritzgießteil kann die Anzahl der benötigten Bauteile deutlich reduziert werden. Dadurch verringert sich der Kosten-/Logistik-/Montage- und Handlingaufwand erheblich. Eine unerwünschte Toleranzaufsummierung wird vermieden. Dadurch kann eine bessere Passung und Abdichtung zum Rohbau des Kraftfahrzeugs hin erreicht werden. Die Bremsleuchte besteht aus einem Teil, das mehrere Komponenten umfasst.The Task is with a brake light, in particular a high set third brake light, a motor vehicle, with at least one lamp body Plastic into which a light source, in particular an LED chip, is embedded, and with a lens, thereby solved that the lamp body with the embedded bulb and the lens of different Components of a multi-component injection molding of a thermoplastic Plastic are formed. Due to the design of the brake light as a multi-component injection-molded part can the number of needed Components are significantly reduced. This reduces the Cost / logistics / assembly and handling effort considerably. An unwanted tolerance accumulation is avoided. This can provide a better fit and seal to the shell of the motor vehicle can be achieved. The brake light consists of a part that includes several components.
Ein bevorzugtes Ausführungsbeispiel der Bremsleuchte ist dadurch gekennzeichnet, dass die Lichtscheibe aus einem transparenten, insbesondere roten Polymethylmethacrylat gebildet ist. Mit diesem Material wurden im Rahmen der vorliegenden Erfindung die besten Ergebnisse erzielt. Es ist jedoch auch der Einsatz von anderen thermoplastischen Werkstoffen denkbar.One preferred embodiment the brake light is characterized in that the lens from a transparent, in particular red polymethylmethacrylate is formed. This material was used in the present Invention achieved the best results. But it is also the one Use of other thermoplastic materials conceivable.
Ein weiteres bevorzugtes Ausführungsbeispiel der Bremsleuchte ist dadurch gekennzeichnet, dass die Lichtscheibe eine längliche Gestalt mit einer umlaufenden Nut aufweist. Die Nut dient zur Aufnahme einer Dichtung, die entweder als separates Teil eingelegt oder angespritzt werden kann.One Another preferred embodiment the brake light is characterized in that the lens an elongated one Having shape with a circumferential groove. The groove is used for recording a seal, either inserted as a separate part or molded can be.
Ein weiteres bevorzugtes Ausführungsbeispiel der Bremsleuchte ist dadurch gekennzeichnet, dass an den Enden der Lichtscheibe jeweils eine Zentriernase ausgebildet ist. Die Zentriernasen dienen dazu, die Bremsleuchte beim Einbau zu zentrieren.One Another preferred embodiment the stop lamp is characterized in that at the ends of Lens each have a centering nose is formed. The centering noses serve to center the brake light during installation.
Ein weiteres bevorzugtes Ausführungsbeispiel der Bremsleuchte ist dadurch gekennzeichnet, dass der Leuchtenkörper aus einem transparenten, insbesondere farblosen Polymethylmethacrylat gebildet ist. Da der Leuchtenkörper aus demselben thermoplas tischen Kunststoff wie die Lichtscheibe gebildet ist, wird ein Recyceln der Bremsleuchte erheblich vereinfacht.A further preferred embodiment of the brake light is characterized in that the lamp body is formed of a transparent, in particular colorless polymethylmethacrylate. Since the lamp body gebil from the same thermoplas tical plastic as the lens is det, recycling the brake light is greatly simplified.
Ein weiteres bevorzugtes Ausführungsbeispiel der Bremsleuchte ist dadurch gekennzeichnet, dass der Leuchtenkörper eine längliche Gestalt aufweist, aus der Anschlussdrähte des Leuchtmittels herausragen. Über die Anschlussdrähte können die Leuchtenkörper an eine Stromversorgungsquelle angeschlossen werden.One Another preferred embodiment the brake light is characterized in that the lamp body a elongated Has shape, protrude from the connecting wires of the bulb. About the leads can the lamp body be connected to a power source.
Ein weiteres bevorzugtes Ausführungsbeispiel der Bremsleuchte ist dadurch gekennzeichnet, dass mehrere Leuchtenkörper einstückig mit einem länglichen Tragkörper ausgebildet sind. Es können zum Beispiel zehn bis zwanzig Leuchtenkörper von dem Tragkörper ausgehen.One Another preferred embodiment the brake light is characterized in that a plurality of lamp body integral with a longish one supporting body are formed. It can to Example ten to twenty luminaire body emanating from the support body.
Ein weiteres bevorzugtes Ausführungsbeispiel der Bremsleuchte ist dadurch gekennzeichnet, dass an dem länglichen Tragkörper Befestigungsmittel, insbesondere Schnapphaken, ausgebildet sind. Die Befestigungsmittel dienen dazu, den Tragkörper mit der Lichtscheibe an einem Kraftfahrzeug zu befestigen.One Another preferred embodiment the stop lamp is characterized in that on the elongated supporting body Fastening, in particular snap hooks are formed. The Fasteners serve to the support body with the lens to fix a motor vehicle.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung, in der unter Bezugnahme auf die Zeichnung ein Ausführungsbeispiel im Einzelnen beschrieben ist. Dabei können die in den Ansprüchen und in der Beschreibung erwähnten Merkmale jeweils einzeln für sich oder in beliebiger Kombination erfindungswesentlich sein.Further Advantages, features and details of the invention will become apparent the following description, with reference to the drawing an embodiment is described in detail. It can in the claims and mentioned in the description Features individually for each itself or in any combination essential to the invention.
