放電灯５は点灯を継続する。 Next, the operation will be explained. The interlock switch 6 is turned on when the discharge lamp 5 is attached to the fixture, and when the main power supply 1 is connected by turning on the main switch (not shown), the main power supply 1 is turned on.
A high voltage obtained by superimposing the voltage of the secondary coil 2b on the voltage of the secondary coil 2b is applied between the electrodes 5a and 5b of the discharge lamp 5 via the starting impedance circuit 4, and the discharge lamp 5 is started. Once started, the starting current creates a terminal voltage across capacitor C 1 which charges capacitor C 2 through resistor R 2 .
When the charging voltage reaches a certain value, the trigger semiconductor switch D breaks over and the semiconductor switch 8 is turned on, and the discharge lamp 5 is connected to the transformer 3.
A main current for steady lighting is supplied from the secondary coil 3b. The above operation is repeated every half cycle, and the discharge lamp 5 continues to be lit.

When FLR110H or FLR110H/100 is used, a 200V commercial power supply is used as the main power supply 1, and the output voltage of the secondary coil 2b is 400V.
The output voltage of each secondary coil 3b is selected to be 260V.

The steady lighting operation using the voltage b is repeated every half cycle, but this operation is performed without interfering with each other because transformers 2 and 3 are independent and separate transformers, and the discharge lamp The startup and lighting of the transformer 5 are performed normally and the lighting continues stably, and even if a circulating current flows between the transformers 2 and 3, its value is negligibly small.
