Abstract

A lighting device for multiple input voltages is provided. The lighting device for multiple input voltages includes a plurality of driving circuits each being electrically connected with the light-emitting unit. Each of the driving circuits receives an AC input voltage, and converts the AC input voltage into a working voltage for use by the light-emitting unit. Each of the driving circuits includes a surge protection device and a rectifier. The surge protection device inputs the AC input voltage. The rectifier is electrically connected with the surge protection device, and rectifies the AC input voltage into the working voltage through the surge protection device for use by the light-emitting unit. A threshold voltage of each of the surge protection devices to prevent a surge is different from each other, so that the AC input voltage received by the driving circuits are different from each other.
