The "two switched in Heilie, per 100 cm long fluorescent tubes 1 have a diameter of 22 mm IUF and contain cylindrical electrodes 2 of purified, 0.2 ism 'thick sheet iron, and their long is 70 mm, its diameter 16 mm contain the tubes. Furthermore, a noble gas base filling of 7-8 Torr from 75 $ neon and 25 fi argon, as well as "some mercury 3, so that a low-pressure mercury discharge develops during operation of the drilling stimulates radiation.

The bores 1 are connected to the secondary winding 5 of the high-voltage transformer 6 designed as a Mpnteltype, which is arranged on the center yoke of the transformer between the two primary winding parts 8, 9 connected in series via the line 7. The primary winding consisting of the two parts 8 and 9 is fed with 220 V via the Uetz switch 10. The no-load voltage of the secondary winding 5 is 1000 Vj. When the eyes are ignited, this voltage drops by 200 V; The total tube operating voltage is at a discharge current of 100 mA 800 Y. The ratio of the transformer voltage drop all, that is, the difference between the open circuit voltage and the tube operating voltage, for the tube operating voltage, is 20-80, the two parts of the primary winding have the same size ratio on ι part 8 contains $ 20, part 9 $ 80 of the primary winding.

"The weight of the transformer 6 is about 2.6 kg. In operations, the lighting system shown results in a cos 5 of about 0.85-0.9. This unusually high power factor means a considerable advantage because of the low current load on the Uetz.
