Energy saving lamp bead

The utility model discloses an energy saving lamp bead which is simple in structure, high in light brightness and long in service life. The lamp bead comprises a filament and a glass casing. The cavity of the glass casing is equipped with a metal support bar to support and fix the filament. The top of the metal support bar is fixedly mounted on the top of the glass casing while the bottom of the metal support bar is connected to a molybdenum foil sheet I. The top of the filament is fixed on the upper portion of the metal support bar while the bottom of the filament is connected to a molybdenum foil sheet II. The molybdenum foil sheet I and the molybdenum foil sheet II are connected respectively with a lamp base I and a lamp base II. To support and fix the filament, the lamp bead of the utility model uses the fine metal support bar which at the same time, may also play the role of a conductive line so that the internal structure of the lamp bead is simplified, the light brightness is improved, the stability of
