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

Embodiment 1

[0025] Example 1. Such as image 3 , 4 As shown, it is spirally wound by the filament secondary winding body 4, wherein the filament secondary winding body 4 is spirally wound by the filament primary winding body 3, as shown in Figure 5 shown. The primary winding body 3 of the filament is wound by three main tungsten wires 1 and one molybdenum wire 7 that are close in parallel, and an auxiliary tungsten wire 2 that is spirally wound on the three main tungsten wires 1 and molybdenum wire 7. into, the three main tungsten wires 1 have the same diameter, such as figure 1 , 2 shown. The diameter and spiral coefficient of the main tungsten wire 1 and the auxiliary tungsten wire 2 should be selected according to the power of the lamp. The diameters of the three main tungsten wires 1 can also be different, and the resistance can be adjusted through different combinations of the diameters of the three main tungsten wires 1 .

Abstract

The invention discloses a filament of a main-auxiliary type triple-helix energy-saving lamp with a plurality of main wires; the filament is formed by winding a quadric winding body (4) of the filament in a spiral shape, the quadric winding body (4) of the filament is formed by winding a once winding body (3) of the filament in a spiral shape, and the once winding body (3) of the filament is formed by winding three or more main tungsten filaments (1), three or more molybdenum filaments (7) and one or more auxiliary tungsten filament(s) (2) which is / are wound on the three or more main tungsten filaments (1) and molybdenum filaments (7) in a spiral shape. The filament of the invention has the characteristics of higher storage quantity of electronic powder, stronger bombardment resistant capacity, high pyrometric effect, more rapid temperature raise and long service life; furthermore, when in production, the winding speed is higher, and the wire winding efficiency is also higher; therefore, filament breakage hardly occurs when winding, and the qualification rate of products is improved.

Description

technical field [0001] The invention relates to a filament of an energy-saving lamp and a manufacturing method thereof, in particular to a multi-main filament wound by three or more main tungsten wires, one molybdenum wire and one or more auxiliary tungsten wires Main and auxiliary triple-helix energy-saving lamp filaments 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...
