Vacuum sealed incandescent lamp with filament support structure |
摘要 |
A subminiature incandescent lamp has a substantially cylindrical base to which a glass envelope enclosing the interior of the lamp is sealed. A pair of contact wires or pins are made of a metal alloy that has substantially the same thermal expansion coefficient as the glass base. The contact pins are embedded and sealed to the glass base in a gas-tight manner, with a glass-to-metal seal. The contact pins extend below the base to provide external connections of the lamp to a power source. The pins also extend into the interior of the lamp, and provide electrical contact to a filament which is mounted between them. A filament support wire is anchored in the glass base at one end thereof and has a loop at its other end in which the mid-section of the filament rests and is mechanically supported. |
