Abstract
A light bulb apparatus includes a light bulb shell, a bulb head, and a heat sink cup. The heat sink cup has a first end connected to the light bulb shell, and a second end connected to the bulb head. The light bulb apparatus includes a flexible filament and a central support. The flexible filament has a first terminal and a second terminal, and the central support provides a first electrode electrically connected to the first terminal, and provides a second electrode for electrically connected to the second terminal. The light bulb apparatus includes an expanding structure and a driver module. The expanding structure is mechanically coupled to the central support, and includes a plurality of holding portions for holding the flexible filament. The driver module is electrically connected to the bulb head and the central support for providing electrical power to the flexible filament.
