Problems solved by technology

[0005] What the present invention aims to solve is the problem that the current electronic ballast has a single output characteristic and cannot match the characteristics of different types of fluorescent lamps. By using the tap technology in the inductance coil, a general-purpose inductor is provided, which can produce A variety of inductances enable the ballast to produce a variety of output characteristics to match the characteristics of a variety of fluorescent lamps, prolong the life and efficiency of fluorescent lamps, and reduce the pollution of the earth's environment caused by frequent replacement of ballasts

Embodiment Construction

[0022] Example 1: A general-purpose inductor for electronic ballasts with 4 tap points, the material of its magnetic core 1 is Siemens N27, specification EE25, gap: pad insulating paper 1.2mm, Siemens N27 technical parameters are listed in Table 2 below:

[0023] Table 2:

[0024]

[0025] The wire diameter Φ of coil 2 is 0.30mm, and the number of coil turns between each tap point is listed in the following table 3:

[0026] table 3:

[0027] endpoint

[0028] In this way, the general-purpose inductor for electronic ballasts of the present invention is formed, and the four tap points form three kinds of inductances, which can meet the requirements of fluorescent lamps commonly used in domestic daily life and work, and have extensive general-purpose characteristics.

Abstract

A general inductor of electronic ballast, belonging to an electron component, especially an inductor applied to the electronic ballast, capable of adjusting the inductance and being applied to fluorescent lamps with each power. The general inductor of electronic ballast of this invention is composed of a magnetic core and a coil surrounded on the magnetic core, wherein more than two of tapping points are on the coil, different tapping points generate different inductances which are matched with the corresponding feature of the fluorescent lamp. Due to the commonality, the general inductor of electronic ballast of this invention is able to enable the single one electronic ballast to generate plural features which are satisfied to match with the fluorescent lamps with each feature, and the service life of the fluorescent lamp is enlarged and the best light efficiency can be developed, at the same time the target of saving energy can be achieved, and the waste caused by unmatched features can be avoided; at the same time, the service life of the electronic ballast can be correspondingly enlarged and the back repair rate is reduced.

Description

technical field [0001] The invention belongs to an electronic component, in particular to an inductor used in electronic ballasts, adjustable inductance, and commonly used in fluorescent lamps of various powers. Background technique [0002] Since the advent of fluorescent lamps, because their luminous efficiency is much higher than that of incandescent lamps and tungsten halogen lamps, they have become the most energy-saving electric light source and have been widely used. A main electric light source. Correspondingly, ballasts used with fluorescent lamps to stabilize the current of fluorescent lamps have become a hot research topic in the field of power electronics. Before the 1980s, traditional low frequency (50hz) inductive ballasts were widely used. This kind of ballast has the characteristics of mature technology, high reliability, and low price, but it needs a "starter" to start to work, and it is large in size, heavy in weight, high in power consumption, noisy, and...
