Abstract
A filament structure and a bulb having the filament structure. The filament structure comprises at least three filament substrates. Each of the at least three filament substrates has a first end and a second end spaced apart from each other. Respective sections between the first ends and the second ends of the at least three filament substrates rotatably extend around an axis. An angle at which the sections of the at least three filament substrates between the first ends and the second ends are wound around the axis is not greater than 720 degrees. The filament structure and the bulb having the filament structure are convenient to process and install, achieve multi-angle omni-directional illumination, and meet the requirements of heat dissipation. The filament structure has an attractive appearance that is easily used for decoration.
