Abstract

The invention relates to a lighting load abnormality detecting device, the device including a power supply module, which is configured to provide power supply for the detecting device and the lighting load connected with the detecting device; a detecting circuit is configured to detect the abnormal state of the lighting load; a control module is configured to judge whether the lighting load is abnormal or not according to the detecting circuit feedback detection information; the detecting circuit includes a parallel PWM detection circuit and a static detection circuit; the static detecting circuit is configured to independently detect anomalies when the abnormality detecting device has no pulse loading or to cooperate with the pulse width modulation detecting circuit to jointly detect anomalies when there is pulse loading.
