LED filament module and LED light bulb

An LED light bulb, comprising:

• a bulb shell;
• a bulb base connected with the bulb shell;
• a driving circuit disposed in the bulb base;
• two conductive supports installed in the bulb shell and electrically connected to the driving circuit;
• an LED filament module installed in the bulb shell, comprising:
• a first connecting portion and a second connecting portion, the first and the second connecting portions electrically connecting to the two conductive supports both of the first connecting portion and the second connecting portion have a shape surrounding the center axle of the bulb base;
• a plurality of LED filaments, each of the LED filaments comprising a first conductive electrode and a second conductive electrode opposite to the first conductive electrode, the first conductive electrodes being connected to the first connecting portion, and the second conductive electrodes being connected to the second connecting portion;
• and
• a plurality of filament brackets, wherein the filament brackets are connected between the first connecting portion and the second connecting portion, and each of the LED filaments is respectively attached to each of the filament brackets,
• wherein, the first connecting portion comprises insulation portions, the second connecting portion comprises insulation portions, the first connecting portion and the second connecting portion are made by conductive materials except the insulation portions, and the insulation portions of the first connecting portion and the second connecting portion are arranged in a staggered manner to allow currents to flow through each of the LED filaments in one direction.
