<p>The filament 3 is attached to leads 4 and 5 which are joined at one end by an insulating bead 6. This forms a self-supporting filament mount with the lead 5 extending from the bead 6 arround the filament 3 in a generally helical or angled path to minimize obstruction of the emitted light. A free end 7 of the lead 5, extending beyond the filament 3, passes through one end of the bulb 1 to form one terminal. At the other end a press seal is formed in which the end of the lead 5 is embedded while the lead 4 passes through to form a second terminal of the lamp.</p> |
