Beschreibung
Zusammenfassung:	The invention discloses a method for manufacturing a core column special for an LED filament lamp. The method includes the steps that a horn, a guide filament, an air exhausting rod and a solid bar are placed into a utensil corresponding to a core column machine table, the core column without sticking the filament is manufactured by preheating, heating, flattening forming, blowing, holing and annealing, and then the solid bar heats the sticking filament to manufacture the core column special for the LED filament lamp. The method has the advantages that the LED filament lamp has the effects of energy saving and emission reduction, the LED filament lamp has the characteristics of low currents and high voltages, hence, the LED lighting heating and driver cost can be effectively lowered, consumed energy is reduced by 80% compared with an incandescent lamp with the same lighting effect, and the effect is striking.
