An illumination apparatus includes a power supply, a pulse width modulation (PWM) circuit, a switching unit, and an illuminating unit. The power supply supplies a supply voltage to the PWM circuit and the illuminating unit. The PWM circuit outputs a first level voltage by being fully charged by the voltage of the power supply and outputs a second level voltage by being fully discharged. The switching unit is turned off according to the first level voltage and controls the illuminating unit to stop emitting light. The switching unit is turned on according to the second level voltage and controls the illuminating unit to emit light.

A method protects personal data of an electronic device. Different capacitance values between a plurality of points of a fingertip and an electrode layer of a capacitive touch screen of the electronic device are detectable when the capacitive touch screen is touched by the fingertip, and a representation of a fingerprint is acquired according to distribution of the detected capacitance values. If the acquired fingerprint does not match with any predetermined fingerprint, predetermined personal data of the electronic device is protected. If the acquired fingerprint matches with at least one of the predetermined fingerprints, the protection of the personal data is released.
