Abstract

Die Erfindung betrifft eine Hochdruckentladungslampe, insbesondere eine quecksilberfreie Hochdruckentladungslampe für einen Fahrzeugscheinwerfer, mit einem Lampensockel (1) und einem axialsymmetrischen Entladungsgefäß (30), in dessen Entladungsraum (300) eine Metallhalogenide enthaltende ionisierbare Füllung und Elektroden (31,32) zur Erzeugung einer Gasentladung angeordnet sind. Erfindungsgemäß ist das Entladungsgefäß (30) mit einer lichtdurchlässigen, partiellen Mattierung (37) versehen, die auf einen sich über einen Teil des Entladungsgefäßumfanges erstreckenden Abschnitt der Innenseite oder Außenseite des Entladungsgefäßes (30) beschränkt ist, wobei dieser Abschnitt eine wohldefinierte Lage bezüglich des Lampensockels (1) aufweist. Außerdem ist ein einfaches Herstellungsverfahren für die partielle Mattierung (37) angegeben, die auf der Innenseite des Entladungsgefäßes (30) angeordnet ist.

Figure imgaf001
The invention relates to a high-pressure discharge lamp, in particular a mercury-free high-pressure discharge lamp for a vehicle headlight, having a lamp base (1) and an axially symmetrical discharge vessel (30), in the discharge space (300) containing a metal halide ionizable filling and electrodes (31,32) for generating a gas discharge are arranged. According to the invention, the discharge vessel (30) is provided with a translucent, partial matting (37) which is limited to a portion of the inside or outside of the discharge vessel (30) extending over part of the discharge vessel circumference, this section having a well-defined position relative to the lamp cap (1). In addition, a simple production method for the partial matting (37) is provided, which is arranged on the inside of the discharge vessel (30).
