The utility model has advantages of firm structure, great storage capability of a filament electronic powder, good start-up performance, and long service life.
Description
Technical field
The utility model relates to a kind of filament, particularly the dual main and auxiliary type clubbed filament of a kind of how auxiliary silk.
Background technology
The life-span of power saving fluorescent lamp negative electrode depends primarily on the ability of the resistance to Ions Bombardment of its filament and the ability of quick excitation electron, when filament can not heat up or heat up the electron deficiency that slowly causes cathode emission when lighting fluorescent lamp maybe the electronic powder on being attached to filament exhausts, filament is because being subject to Ions Bombardment to produce fracture of wire, the life-span of the fluorescent lamp knot that comes to an end.Therefore, how to strengthen the ability of the resistance to Ions Bombardment of filament, the storage capacity of the intensification usefulness of raising filament and raising electronic powder has become and has extended filament and the key in power saving fluorescent lamp life-span.
At present, the multi-helical structure that the filament of the power saving fluorescent lamp on market adopts is around to the clubbed filament becoming, and structure is firm not, the electronic powder of storage is also insufficient, cause cathode activation difficulty, filament energising to start slow, electricity-saving lamp is occurred early stage yellow black, the useful life of fluorescent tube is undesirable.
Utility model content
The purpose of this utility model is, provides a kind of how auxiliary silk dual main and auxiliary type clubbed filament.The utlity model has sound construction; Filament electronic powder reserves are large, and startability is good, the advantage that the life-span is long.
The technical solution of the utility model: the dual main and auxiliary type clubbed filament of how auxiliary silk, is characterized in: it comprises by winding body of filament and is wound in the shape of a spiral the spiral club shaped structure forming on two main tungsten filaments of secondary side by side and a secondary molybdenum filament; Two main tungsten filaments of secondary side by side and secondary molybdenum filament between two near; Winding body of described filament comprises side by side one once main tungsten filament and a molybdenum filament, and is spirally wrapped around once main tungsten filament side by side and two above auxiliary tungsten filaments on a molybdenum filament; Described two above auxiliary tungsten filaments are side by side near shape.
In the above-mentioned dual main and auxiliary type clubbed filament of how auxiliary silk, the diameter of described once main tungsten filament is 0.0363～0.0406 ㎜; The diameter of the main tungsten filament of described secondary is 0.0513～0.0574 ㎝; The diameter of described auxiliary tungsten filament is 0.0197～0.0222 ㎜; The diameter of a described molybdenum filament is 0.05～0.08 ㎜; The diameter of described secondary molybdenum filament is 0.18～0.22 ㎜.
Compared with prior art, winding body of filament that the utility model adopts how auxiliary thread master-slave type to be wound around is again wrapped on two main tungsten filaments of secondary and forms bar-shaped helical structure, and this structure has also coordinated the size of each main tungsten filament and auxiliary tungsten filament, make filament more firm; Also greatly increased the ability of filament store electrons powder simultaneously, make electronic powder reserves higher, cathode activation is more prone to, shortened filament preheating time, filament energising starts faster, has improved the bombardment resistance energy of filament, and resistance to bombardment ability is stronger, avoid the filament phenomenon of turning black in early days, extended the useful life of filament.
Accompanying drawing explanation
