Abstract:
A spiral pulse generator is used to start the high-pressure discharge lamp, and is accommodated directly in the outer bulb of the lamp. The spiral pulse generator is surrounded by a ferritic material so that it acts as a starting transformer.
Abstract:
The invention relates to a compact high-voltage pulse generator based on a spiral pulse generator, with the spiral pulse generator being entirely or partially surrounded by a ferritic material. The invention likewise relates to a dip-coating method for coating a spiral pulse generator with a ferritic layer, in which the spiral pulse generator is dipped into a low-viscosity slip and, once the slip has dried, is sintered at temperatures of 500 to 900°C. The invention also relates to a high-pressure discharge lamp having a discharge vessel which is accommodated in an outer bulb, with a starting apparatus being integrated in the lamp and producing high-voltage pulses in the lamp, with the starting apparatus being a spiral pulse generator which is accommodated in the outer bulb, with the generator acting as a starting transformer, since it is entirely or partially surrounded by a ferritic material.
Abstract:
The invention relates to a compact high-voltage pulse generator based on a spiral pulse generator, wherein the spiral pulse generator is configured as an LTCC component and wound of at least two ceramic foils and metal layers applied thereon, and wherein between the metal layers of the spiral pulse generator a multi-layer structure comprising at least one first layer having a capacitively acting ceramic with high permittivity of at least er = 10 and at least one second layer having an inductively acting ceramic with high permeability of at least µr = 1.5 is provided, wherein the at least one inductively acting ceramic layer is insulated by the at least one capacitively acting ceramic layer. The invention also relates to a high-pressure discharge lamp having such a spiral pulse generator. The invention further relates to a method for producing ceramic spiral pulse generators.
Abstract:
The invention relates to a compact high-voltage impulse generator based on a spiral impulse generator which is entirely or partially surrounded by a ferritic material. The invention also relates to a coating method for coating a spiral impulse generator with a ferritic layer, according to which the spiral impulse generator is either immersed into a low-viscosity slurry, and sintered at temperatures of between 500°C and 900°C once the slurry has been dried, or is surrounded by a ferritic casting compound which is then hardened thermally or by UV radiation. The invention also relates to a high-pressure discharge lamp comprising a discharge vessel which is received in an outer piston. An ignition device generating high-voltage impulses in the lamp is built into the lamp and is a spiral impulse generator received in the outer piston and acting as an ignition transformer due to the fact that it is entirely or partially surrounded by a ferritic material.
Abstract:
The invention relates to a ceramic electrode having a shaft and a head, wherein at least a part of the head is made of ceramic material, in particular LaB6 or carbides of HF and/or tantalum.
Abstract:
The associated electrode system is made of tungsten material in four parts, comprising the following four segments: an electrode head, an electrode shaft, a central feedthrough part, and a terminal feedthrough part. The terminal feedthrough part is surrounded by a ceramic collar.
Abstract:
Die vorliegende Erfindung betrifft ein Leuchtmittel (1) mit LEDs (23) auf einem Substrat (2), einem Hüllkolben (23), in welchem das Substrat (2) mit den LEDs (23) angeordnet ist, und einem Sockel (4), wobei mindestens zwei Teilflächen (2a) des Substrats (2) gegenüber dem übrigen Substrat (2b) jeweils um einen Brückenbereich (25), über welchen die jeweilige Teilfläche (2a) mit dem übrigen Substrat (2b) verbunden ist, herausgeklappt und so schräg zu dem für sich flächigen übrigen Substrat (2b) angestellt sind, wobei je Seitenfläche des übrigen Substrats (2b), welche Seitenflächen einander in Bezug auf eine Dickenrichtung des übrigen Substrats (2b) entgegengesetzt liegen, jeweils mindestens eine Teilfläche (2a) herausgeklappt ist, und wobei auf jeder der Teilflächen (2a) mindestens eine der LEDs (23) angeordnet ist.
