Zusammenfassung:When the temperature value detected by a temperature detecting circuit is lower than a previously designated set temperature value, cathode fluorescent lamps (CFLs) are operated to illuminate with a duty ratio of 100% so as to enhance the brightness. When the detected temperature value has become equal to or higher than the previously designated set temperature value, CFLs are operated to illuminate by changing the duty ratio into a user set value.
