When transformer occurs abnormal by the signal that energy storage rectifier circuit exports in lighting device, based on the abnormal signal
Carry out energy accumulation storage；
When the energy of accumulative storage is more than preset energy threshold, the power illuminating device is cut off in control.
9. according to the method described in claim 8, it is characterized in that, the energy in accumulative storage is more than preset energy cut-off
When value, control cuts off the power illuminating device and includes:
When the energy of accumulative storage is more than preset energy threshold, the control circuit of Xiang Suoshu lighting device sends control letter
Number, so that the control circuit after receiving the control signal, controls the disconnection of the conversion circuit in the lighting device, from
And cut off the power illuminating device.
