Abstract (en)
A fuse for a lamp (10) is formed in a flare (40) of the lamp. Leads (26) for an energizable light source (28), such as a tungsten filament, pass through a cavity (58) in the flare. A portion (60,62) of each lead within the flare cavity is fusible. Arcing is dissipated by an arc-quenching filler material (76), such as glass beads, which fill the flare cavity and surround the fusible portions. A sealant (86) retains the beads in the cavity. <IMAGE>
