Abstract (en)
An LED light bulb (1) and a fabrication method thereof are provided. A plurality of power wires (111,112) for supplying electricity to an LED filament (12) are fixed to form a power wire supporting structure for supporting and fixing the LED filament (12) in position, without using a stem of a conventional LED light bulb, thereby simplifying fabrication processes of the LED light bulb (1) and reducing fabrication costs thereof. Moreover, the LED light bulb does not require an internal space for accommodating the stem, and thus its length can be effectively reduced to ideally become a small-size light bulb.
