    • The present invention relates to a preheating control device controlling lamp preheating, a lamp driving device including the same, and a preheating control method thereof. A preheating control device according to an exemplary embodiment of the present invention generates a preheating control voltage that is changed according to a passage of a preheating time of a lamp and generation of a lamp current of the lamp. An oscillator signal having a frequency according to a preheating control voltage is generated, and if the lamp current is generated in the lamp, the preheating control voltage is changed to more than a predetermined reference voltage such that the frequency of the oscillator signal may be decreased.
    • 本发明涉及一种控制灯预热的预热控制装置,包括该预热控制装置的灯驱动装置及其预热控制方法。 根据本发明的示例性实施例的预热控制装置产生根据灯的预热时间的经过和灯的灯电流的产生而改变的预热控制电压。 产生具有根据预热控制电压的频率的振荡器信号,并且如果在灯中产生灯电流,则预热控制电压被改变到大于预定参考电压,使得振荡器信号的频率可能减小 。
