Bei der Lampe gemäß des oben beschriebenen, bevorzugten Ausführungsbeispiels handelt es sich um eine Bremslicht- oder Blinklichtlampe für ein Kraftfahrzeug. Diese Lampe kann auf mehrere verschiedene Arten montiert werden und ist daher universell im Kraftfahrzeug einsetzbar. Sie kann sowohl als Blinklichtlampe in einen Frontscheinwerfer des Kraftfahrzeugs als auch als Blinklicht- oder Bremslichtlampe in einer Heckleuchte des Kraftfahrzeuges montiert werden. Drei unterschiedliche Montageoptionen werden nachstehend kurz erläutert. In the lamp according to the preferred embodiment described above is a brake light or turn signal lamp for one Motor vehicle. This lamp can be assembled in several different ways are and can therefore be used universally in motor vehicles. It can both as a flashing light bulb in a headlight of the motor vehicle as also as a flashing light or brake light lamp in a rear light of the motor vehicle to be assembled. There are three different mounting options explained briefly below.

Montage auf einer PlatineMounting on a board

Zur Montage auf einer Leiterplatine in einer mit einem Reflektor ausgestatteten Leuchte (z.B. in einer Kfz-Heckleuchte), wird die Lampe durch Hineinstecken der Lampe in den Reflektor vormontiert. Dabei verrasten die Rastnasen 8a im Leuchtenreflektor. Die Unterkanten der Rastnasen 8a dienen als Referenzebene für die Justage der Lampe im Reflektor. Die Leiterplatine ist nach der Montage zwischen den Unterkanten der beiden Rastnasen 8a und den vier abgespreizten Federelementen 10 angeordnet. Die abgespreizten Enden 5a der beiden Kontaktfahnen stellen den elektrischen Kontakt zu den Leiterbahnen auf der Leiterplatine her. Zum Entfernen der Lampe wird der Befestigungsring 6 so weit gedreht, daß sich die Rastverbindung der Rastnasen 8a im Reflektor löst.For mounting on a printed circuit board in a one equipped with a reflector Lamp (e.g. in a motor vehicle rear light), the lamp is inserted into it the lamp pre-assembled in the reflector. The latches snap into place 8a in the light reflector. The lower edges of the locking lugs 8a serve as Reference plane for the adjustment of the lamp in the reflector. The circuit board is after assembly between the lower edges of the two locking lugs 8a and the four spread spring elements 10 are arranged. The spread Ends 5a of the two contact tabs make electrical contact with the Conductor tracks on the circuit board. To remove the lamp, the Fastening ring 6 rotated so far that the locking connection of the locking lugs 8a in the reflector releases.

Montage in einem Scheinwerfer an einem SteckerInstallation in a headlight on a plug

Zur Montage der Lampe an einem Stecker in der rückwärtigen Reflektoröffnung eines Kraftfahrzeugscheinwerfers wird die Lampe zunächst in der rückwärtigen Reflektoröffnung mittels der Rastnasen 8a verrastet. Die Kante der rückwärtigen Reflektoröffnung ist dabei zwischen der Unterkante der Rastnasen 8a und den vier abgespreizten Federelementen 10 angeordnet. Der wird auf den Lampensockel 3 aufgesteckt. Dabei greift ein zapfenartiges Steckerteil in die Aussparung 3b des Lampensockels. Die beiden Steckerkontakte sind nach der Montage in den Kammern 3c des Sockels angeordnet und befinden sich im elektrischen Kontakt mit den Kontakfahnen der Lampe. Der Stecker weist einen umlaufenden Dichtungsring auf, der an der Außenwand des Reflektors anliegt und die rückwärtige Reflektoröffnung gegen Luftfeuchtigkeit abdichtet. Zum Auswechseln der Lampe wird zunächst der Stecker abgezogen und anschließend der Befestigungsring 6 so weit gedreht, daß sich die Rastverbindung der Rastnasen 8a im Reflektor löst. For mounting the lamp on a plug in the rear reflector opening of a motor vehicle headlight, the lamp is first in the rear reflector opening locked by means of the locking lugs 8a. The edge the rear reflector opening is between the lower edge of the Lugs 8a and the four spread spring elements 10 are arranged. The is attached to the lamp base 3. A pin-like grips Plug part in the recess 3b of the lamp base. The two plug contacts are arranged after assembly in the chambers 3c of the base and are in electrical contact with the contact tabs of the lamp. The connector has a circumferential sealing ring on the outer wall of the reflector abuts and the rear reflector opening against Humidity seals. To replace the lamp, first the Disconnected plug and then turned the fastening ring 6 so far, that the locking connection of the locking lugs 8a is released in the reflector.

Montage auf einer MontageplatteMounting on a mounting plate

Zur Montage der Lampe auf einer Montageplatine mit zapfenartigen Fassungsteilen wird die Lampe auf die Montageplatte aufgesteckt. Dabei greift ein zapfenartiges Fassungsteil in die Sockelaussparung 3b und die federnd ausgebildeten Fassungskontakte der Montageplatine werden dabei in die Kammern 3c eingeführt, so daß sie einen elektrischen Kontakt zu den Kontaktfahnen der Lampe herstellen. Anschließend wird die Montageplatte mit der bzw. den aufgesteckten Lampen in dem Leuchtenreflektor befestigt. Die Rastnasen 8a und der Befestigungsring 6 sind bei dieser Art der Montage funktionslos.For mounting the lamp on a mounting board with peg-like socket parts the lamp is attached to the mounting plate.
