Abstract
An LED filament light including a bulb, a support bar, at least two electrode wires and at least two LED filament strips. Each LED filament strip including a base, an LED chip is set on the base and an electrode chip is fixed at both ends of the base. One end of the electrode chip is electrically connected with an LED chip on the base, the other end of the electrode chip is electrically connected with an electrode chip of another LED filament or electrically connected to one end of the electrode wires so that the support bar is fixed to the bulb, and the other end is connected with at least one. As the support bar is set to replace the existing LED filament light core and metal wire, and creatively the LED filament electrode chips directly is connected to each other.
