| 摘要 |
The invention concerns an energy-saving light marking device with low power consumption comprising a head transformer (10) whereof the primary winding (12) is powered by an alternating current source and a plurality of marking lamps in series (14-1 to 14-3) connected to the terminals of the secondary winding (13) of the head transformer, each of the marking lamps consisting of a fluorescent lamp (16-1 to 16-3) powered by the secondary winding of a second transformer (18-1 to 18-3), the primary windings of all the secondary transformers of the marking lamps being connected in series between the terminals of the secondary winding (13) of the head transformer. According to the main characteristic of the invention, the starting of each of the fluorescent lamps (16-1 to 16-3) is provided by the voltage surge generated at the terminals of the secondary winding of the secondary transformers (18-1 to 18-3) when the primary winding of the secondary transformers is powered while the lamps are not yet started.
