摘要： The disclosure relates to a life prediction system for a fan of a lamp. The system comprises a fan signal detecting module to detect at least one working parameter of the fan; and a micro control unit to receive the working current signal, the environment temperature signal and the working rotation speed signal of the fan. The detecting module comprises a current detecting unit to detect a working current of the fan and output a working current signal; a temperature detecting unit to detect a working environment temperature of the fan and output an environment temperature signal; and a rotation speed detecting unit to detect and output a working rotation speed signal of the fan. The micro control unit calculates a predicted residual life of the fan based on the received working current signal, the environment temperature signal, the working rotation speed signal, through the life model of the fan.

摘要： A relamping circuit topology to provide a lamping signal in ballast circuits used to power heated filament gas discharge lamps. The relamping circuit includes a low level DC power source, a differential capacitance and a switching device coupled to the differential capacitance. The differential capacitance is configured to produce a relamping signal. The relamping circuit topology also includes an electric current path configured to direct a flow of direct current from the low level DC power supply through a filament of the gas discharge lamp, and to the differential capacitance such that breaking and restoring the electric current path activates the relamping signal.
