Fault detection apparatus and fault detection method thereof
A fault detection apparatus coupling with a lamp module includes a current detector and a controlling module. The controlling module is coupled with the current detector. A fault detection method of a fault detection apparatus is also provided in the present disclose. The method includes providing a current detector to detect a current variation of one lamp of a lamp module in a period, and provide a controlling module to compare the current variation with a reference value stored in the controlling module to determine a state of the lamp module.
