H05B41/2886 - CPC Classification

Classification description:

Circuit arrangements or apparatus for igniting or operating discharge lamps; Circuit arrangements in which the lamp is fed by power derived from dc by means of a converter, e.g. by high-voltage dc using static converters with semiconductor devices and specially adapted for lamps without preheating electrodes, e.g. for high-intensity discharge lamps, high-pressure mercury or sodium lamps or low-pressure sodium lamps; Static converters especially adapted therefor; Control thereof comprising a controllable preconditioner, e.g. a booster
