摘要： 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.

摘要： The present invention relates a diagnosis device for detecting an end of lamp life of a lamp, a diagnosis method, and a lamp ballast circuit using the same. The diagnosis device generates a reference lamp voltage by adding a predetermined reference voltage to a distributed voltage corresponding to a lamp voltage applied to a lamp and generates an integrated lamp voltage by integrating the reference lamp voltage. The diagnosis device compares the integrated lamp voltage with a normal range that an integrated lamp voltage has when the lamp is in a normal state.
