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 uses a material with a matched ∈ and μ.
Claims16
A high-pressure discharge lamp comprising a discharge vessel accommodated in an outer bulb, wherein a starting device is integrated into the lamp and it generates the high-voltage pulses in the lamp, characterized in that the starting device is accommodated in the outer bulb, wherein the starting device is a spiral pulse generator which is made from a heat-resistant material, in particular from LTCC, wherein this material comprises ceramic films and metallic wetting agent, and wherein the ceramic material is a mixture of two materials, of which the first material has a relative permittivity ∈r of 2 to 1000 and the second material has a relative permeability μr of 1 to 5000.
A high-pressure discharge lamp with a discharge vessel and an associated starting device, wherein the starting device generates high-voltage pulses and comprises a spiral pulse generator, characterized in that the spiral pulse generator is made from an LTCC material.
A compact high-voltage pulse generator based on a spiral pulse generator, characterized in that the spiral pulse generator is designed as an LTCC component made of ceramic films and metallic conductive paste as wetting agent on the film.
