Abstract
The present invention relates to glow-switch starters, lighting devices therewith and use thereof. The glow-switch starteris suitable for use with three phase supply voltages substantially higher than the common 230V supply voltage. This allows more efficient gas discharges in e.g. fluorescent lamps, and/or more lamp power, and/or less energy losses in ballastsand lamp electrodes. To make the glow-switch starter suited for such use, according to the invention, the gas fillingof the starteris adapted. An important criterion is that the glow current in the steady state operation of the fluorescent lamp that is started by the starter is small enough to prevent closing of the (bimetallic) switch.
