H05B41/14 - CPC Classification

Classification description:

Circuit arrangements or apparatus for igniting or operating discharge lamps Circuit arrangements

Sub-classes:

H05B41/16 » in which the lamp is fed by dc or by low-frequency ac, e.g. by 50 cycles/sec ac, {or with network frequencies} 44
H05B41/24 » in which the lamp is fed by high frequency ac, {or with separate oscillator frequency} 120
H05B41/26 » in which the lamp is fed by power derived from dc by means of a converter, e.g. by high-voltage dc 4
H05B41/30 » in which the lamp is fed by pulses, e.g. flash lamp 49
H05B41/36 » Controlling 271
H05B41/46 » Circuits providing for substitution in case of failure of the lamp 29
