Problems solved by technology

[0002] With the improvement of living standards, people have relatively high requirements for daily lighting. At the same time of lighting, they also need relatively high processing requirements for fluorescent lamps. At that time, the previous aging process method was not perfect, resulting in insufficient pressurization method during aging, resulting in filament breakage in the lamp tube due to high pressure in a short period of time, resulting in defective products in the inspection process, reducing the qualified rate of product production and improving production cost

Abstract

The invention aims at providing an aging processing technology for a lamp filament of a lamp tube of a fluorescent lamp. The aging process comprises the steps of 1, conducting aging preparation on the lamp tube; 2, conducting preheating before aging of the lamp tube; 3, conducting high-voltage forced starting; and 4, then, conducting ignition and extinguishing treatment on the lamp tube obtained after high-voltage forced starting, and conducting secondary starting. The high voltage is raised more than once step by step, the lamp tube is preheated in advance, and therefore stability of voltage boosting conducted in the aging process can be improved; the situation that the lamp filament is ruptured due to the fact that the voltage is raised excessively fast is reduced; the defective product rate is decreased; the high-quality product rate of products is increased; and production cost is lowered.

Description

technical field [0001] The invention relates to the field of fluorescent lamp processing technology, in particular to the improvement of the filament processing of fluorescent lamp tubes, and in particular to a sophisticated processing technology for fluorescent lamp tube filaments. Background technique [0002] With the improvement of living standards, people have relatively high requirements for daily lighting. At the same time of lighting, they also need relatively high processing requirements for fluorescent lamps. At that time, the previous aging process method was not perfect, resulting in insufficient pressurization method during aging, resulting in filament breakage in the lamp tube due to high pressure in a short period of time, resulting in defective products in the inspection process, reducing the qualified rate of product production and improving production cost. [0003] Therefore, a aging processing technology for the filament of a fluorescent lamp tube is pro...
