Abstract
A lighting device with fault detection and self-locking control function, which includes a light-emitting module, a power module, a voltage detection module, a signal conversion module, a self-locking control module and a signal control module. The power module drives the light-emitting module. The voltage detection module detects the driving voltage of the light-emitting module to generate a detection signal. The signal conversion module converts the detection signal into an operating status signal. The self-locking control module controls the power module. The signal control module controls the self-locking control module according to the operating status signal. The signal control module activates the self-locking control module when the operating status signal is in an abnormal state, and the self-locking control module controls the power module to stop driving the light-emitting module and enter a self-locking state.
