Abstract

Die Erfindung betrifft einen Reflektor für eine Lampe, insbesondere mit einem Hochdruck-Gasentladungs-Leuchtkörper, mit einer Innenfläche und einer Außenfläche.The invention relates to a reflector for a lamp, in particular with a high pressure gas discharge filament, with an inner surface and an outside surface.

Um bei einem Bersten des Leuchtkörpers zu vermeiden, daß Partikel des Reflektors zentrifugal nach außen fliegen, wird gemäß der Erfindung eine Beschichtung aus temperaturfestem, zähem Kunststoff vorgesehen.To avoid bursting of the filament that particles of the Flying the reflector centrifugally to the outside is one according to the invention Coating made of temperature-resistant, tough plastic.
