1. A life prediction system for a fan of a lamp, comprising:
a fan signal detecting module configured to detect at least one working parameter of the fan, comprising:
a current detecting unit configured to detect a working current of the fan and output a working current signal;
a temperature detecting unit disposed at at least one of an air inlet or an air outlet of the fan, the temperature detecting unit being configured to detect a working environment temperature of the fan and output an environment temperature signal;
a rotation speed detecting unit configured to detect and output a working rotation speed signal of the fan; and
a communication device to transmit the working current signal, the environment temperature signal and the working rotation speed signal of the fan to a micro control unit located remote from the fan signal detecting module, the micro control unit comprising a storage unit configured to store a life model for a particular model of the fan;
wherein the micro control unit is configured to confirm that the fan has the particular model and, responsive to conforming that the fan has the particular model, calculate a predicted residual life of the fan based on the working current signal, the environment temperature signal, the working rotation speed signal and the life model for the particular model of the fan, the micro control unit transmitting the predicted residual life value for delivery to at least one client in conjunction with a fan replacement signal when the predicted residual life is less than or equal to a pre-set life threshold.
