| Zusammenfassung: | PURPOSE: A lamp driving device is provided to perform miniaturization by detecting an abnormal state through a lamp control part composed of a first diode and a second diode. CONSTITUTION: A lamp driving device(100) includes a power supply part(10), a converting part(20), a lamp part(30), and a lamp control part(40). The power supply part converts an input voltage supplied from outside into an AC voltage. The converting part converts the AC voltage from the power supply part into a driving voltage of a lamp. The lamp part is operated by a driving voltage of the converting part. The lamp control part receives a voltage of the lamp part, and determines an abnormal state of the lamp part. |
