Problems solved by technology

Although the filament with this structure has better anti-bombardment performance and more electronic powder storage capacity, the contact area of ​​the electronic powder is not large enough when the filament is energized and heats up, the cathode activation is relatively slow, and the life of the lamp tube is not very ideal; and if the power To achieve 300W, due to the large working current, the main tungsten wire must choose a thicker tungsten wire. The thicker tungsten wire increases the difficulty of winding, and is also prone to wire breakage. The product qualification rate is low, and it is reliable after being made into a lamp tube. Low sex

The product qualification rate is high.

Description

technical field [0001] The invention relates to a filament of an energy-saving lamp and a manufacturing method thereof, in particular to a dual-main-filament main-auxiliary type which is wound by two main tungsten wires, one molybdenum wire and one or more auxiliary tungsten wires. A three-helix energy-saving lamp filament and a manufacturing method thereof. Background technique [0002] Energy-saving fluorescent lamps are now the most important artificial light source and are widely used all over the world. Especially in the field of industrial and commercial lighting, its high efficiency, good light output, color variety and long service life make it an ideal choice in the above lighting fields. The service life of energy-saving fluorescent lamps is determined by the failure of the lamp tube and the emission of thermal electrons caused by the exhaustion of mercury for the energy-saving fluorescent lamps that meet the specifications after the causes of process defects such...
