Abstract

PURPOSE: To ensure a highly efficient lighting for the luorescent lamp and thus to obtain the proper video output by giving preheating to the fluorescent lamp so that the tube wall temperature may feature a prescribed level before lighting of the fluorescent lamp.
CONSTITUTION: The tube wall temperature detected by temperature detector 3 is applied to arithmetic comparator 5 via amplifier 4. Flip-flop 6 is set by the output of comparator 5 and then switch 7 is turned on. And the power source is connected to high frequency lighting device 8 to light up fluorescent lamp 1. On the other hand, the wakeup signal is applied to the picture information reading device to turn on switch 9. At the same time, flip-flop 6 is reset to turn off switch 7. When signal S falls down after the picture information reading device reads the prescribed original, the power supply is cut off to device 8 to turn off lamp 1.
