Abstract
An LED filament module and an LED light bulb are disclosed. The LED filament module includes one or more LED filaments, a first connecting portion, and a second connecting portion. The LED filaments are spaced from each other. Each of the LED filaments includes a first conductive electrode and a second conductive electrode opposite to the first conductive electrode. The first connecting portion is connected with the first conductive electrodes. The second connecting portion is connected with the second conductive electrodes. The LED filament module has a first type. The LED filaments, the first connecting portion, and the second connecting portion of the first type are in a three dimensional form. One or two between the first connecting portion and the second connecting portion of the first type has a torus shape.
