This invention provides a flash lighting input apparatus and driving method. According to this invention, the flash lighting input apparatus can be a flash lighting keyboard. The flash lighting apparatus comprises a micro control unit, a pulse width modulation unit electrically connects to the micro control unit, a light control unit electrically connects to the pulse width modulation unit, and a lighting unit electrically connects to the light control unit. The micro control unit produces a control signal to the pulse width modulation unit, and the pulse width modulation unit produces a modulation signal according to the control signal. The lighting control unit receives the modulation signal and produces a driving signal according to the modulation signal, and transfers the driving signal to the lighting unit to drive the lighting unit.
