Förfarande och strömkällenhet för stabiliserad drift av en natrium-högtrycksurladdningslampa

摘要

In the case of the method and the power supply unit for the stable operation of a high-pressure sodium discharge lamp using saturated vapour, the power supply unit is controlled in such a manner that the quotient of lamp voltage and lamp current or the impedance of the high-pressure sodium discharge lamp assumes a specific value which results in optical lamp data for the corresponding type of high-pressure sodium discharge lamps.
