Description

The plug-in electric ballast

The utility model relates to a kind of electronic ballast for fluoresent lamp, particularly relates to a kind of electric ballast that utilizes plug and socket to be installed on the light fixture and be convenient to maintain and replace.

Fluorescent lamp is a lighting commonly used in people's daily life, owing to its luminous efficiency height, photochromic getting well and long service life, thereby is widely used in the illumination in various places.Fluorescent lamp is a kind of low-pressure discharge lamp, and the starting voltage and the normal working voltage of lamp tube ends differ greatly, and need use ballast to stablize its operating current when therefore working.In general, all elements with positive voltage-current characteristic all can be used as fluorescent lamp ballast; The efficient height of inductance coil, energy loss is little, is a kind of comparatively desirable ballast.But the volume ratio of inductance type ballast is bigger, and it is also more to consume copper material and iron material; And power factor is very low, generally all below 0.6, have in addition less than 0.4, use inductance type ballast will cause the many unnecessary burden of electrical network in a large number.

People utilize high-frequency ac electrically-ignited fluorescent lighting fixture that many advantages are arranged through discovering, therefore are that the electric ballast of feature also just arises at the historic moment with the frequency conversion.Though also to adopt the inductance coil ballast in the electronic ballast circuit, because frequency thousandfold ground increase, thus when induction reactance is identical, the also corresponding reduction of inductance value, the volume of inductance coil can reduce thereupon.In addition, compare with inductance type ballast, electric ballast also has energy-efficient, no stroboscopic, noiseless, and to series of advantages such as the adaptive capacity of low quality power supply are strong, the low-voltage startability is good, and its power factor can be up to more than 0.9.Therefore, it will be inevitable replacing inductance type ballast with electric ballast.Electric ballast of the prior art, the pattern of its ballasting circuit is a lot, and the ballast performance also has difference, but a common characteristic is arranged, and promptly mostly is installed in the inside of light fixture.In case ballast is damaged, must be with can maintain and replace after the light fixture dismounting, thereby bring great inconvenience to the user.

The purpose of this utility model promptly is the improvement suitable in addition to the structure of fluorescent lamp ballast, to make things convenient for its maintenance and replacing.

To achieve these goals, the utility model utilizes socket and the housing that has ballasting circuit plate and plug to constitute a kind of plug-in electric ballast.Have positioning jack and conductive jack on the socket and be fixed on the light fixture, each conductive jack links with the associated contacts of glimmering lamp lamp base and power supply respectively by lead; The outside of plug has the reference column and the conductive pole of working in coordination with socket positioning jack and conductive jack, and each conductive pole links with the associated contacts of ballasting circuit respectively by lead.After the housing that will have ballasting circuit plate and a plug is extracted, can keep in repair and change electric ballast easily from socket.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model plug-in electric ballast.

Accompanying drawing 1 is the STRUCTURE DECOMPOSITION figure of the utility model middle shell.

Accompanying drawing 2 is the structural representation of socket in the utility model.

Accompanying drawing 3 is the ballasting circuit figure in the utility model.

With reference to the accompanying drawings 1,2,3, the utility model plug-in electric ballast mainly is made of housing, ballasting circuit plate and plug and socket.Housing 1 is the rectangular box of an end opening, is made by cast aluminium or aluminum alloy materials, pushes up on it and the medial surface of going to the bottom has the caulking groove 2 that is used for chimeric installation ballasting circuit plate.The ballasting circuit plate 3 of arranging ballasting circuit be a rectangle, chimeric be installed on that housing pushes up on interior and the caulking groove 2 of the medial surface of going to the bottom in.Plug 4 is square, make by the hard electrical plastics, be fixed on the openend of housing 1 and the shell nozzle end is sealed by screw 5, its outside has the reference column that can insert in the socket and be used for locating 6 and most the conductive poles 7 that can insert socket, each conductive pole 7 by lead 8 respectively with ballasting circuit in associated contacts link.Socket 9 is made and is fixed on the light fixture by the hard electrical plastics, its outside has respectively the positioning jack 10 and the conductive jack 11 of working in coordination with plug reference column 6 and conductive pole 7, and each conductive jack 11 links with the associated contacts of fluorescence lamp base S and power supply respectively by lead 12.

The utility model is simple in structure, maintenance and change convenient, so be particularly suitable for electric ballast as fluorescent lamp.
