High pressure discharge lamp e.g. sodium high pressure lamp, has igniter with spiral-pulse-generator and charging resistor, where charging resistor is made from low temperature co-firing ceramic-material

摘要

The discharge lamp has a discharge receptacle placed in an external piston and kept by a frame, where an igniter is integrated in the discharge lamp and a high voltage pulse is produced in the lamp. The igniter consists of a spiral-pulse-generator (1) and a charging resistor (18), where the charging resistor is made from a low temperature co-firing ceramic (LTCC)-material. The charging resistor is placed in the external piston. Independent claims are also included for the following: (1) a high voltage pulse generator on the basis of a spiral-pulse-generator (2) an igniting unit on the basis of the high voltage pulse generator.
