1. A lighting apparatus, comprising:
a control circuit operating according to a default setting when the control circuit is started;
a light source controlled by the control circuit;
a reset sensor for detecting a status variation, wherein the status variation is caused by an external device outside the lighting apparatus; and
a reset circuit coupled to the reset sensor for generating a reset signal to the control circuit to reset the control circuit when the status variation satisfies a predetermined triggering condition, wherein the status variation comprises a magnetic field variation, wherein the sensor is a Hall effect device for converting the magnetic field variation to a response voltage, wherein the reset circuit determines whether to generate the reset signal by checking the response voltage.
