Abstract

The utility model relates to a quick-starting ballast for fluorescent lamps, comprising coils and a rectifier which is connected with the coils, and the coils are composed of an iron core, a primary coil and a secondary coil. One end of the primary coil is connected with one input end of the rectifier, and one end of the secondary coil is connected with the output end of the negative electrode of the rectifier. The utility model has the advantages of quick starting, low starting voltage (can normally start when the voltage is 150V ), no strobo-flash, etc. and can extend effectively the service life of the fluorescent lamp.

Description

Quick-starting ballast for fluorescent lamp

The utility model relates to that a kind of gaseous discharge lamp burning-point auxiliary equipment---fluorescent lamp starts ballast fast.

Fluorescent lamp is the energy-efficient light source that a kind of output is big, use is wide., fluorescent lamp is different from incandescent lamp, and its burning-point needs auxiliary equipment---ballast and starter, the quality good or not of auxiliary equipment and and the fine or not result of use that directly influences lamp of fluorescent tube coupling.At present the Inductive ballast that fluorescent lamp is commonly used exist stroboscopic effect and line voltage when on the low side fluorescent tube start the shortcoming of difficulty.

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of and does not have stroboscopic effect, fluorescent lamp that starting resistor is low starts ballast fast.

The purpose of this utility model realizes by the following technical solutions: additional filament heating circuit in ballast makes fluorescent tube work under direct current simultaneously.The coil that is made of iron core, primary coil and secondary coil, the rectifier that links to each other with coil are formed fluorescent lamp and are started ballast fast.One of primary coil is terminated at an input of rectifier, and one of secondary coil is terminated at "-" utmost point output of rectifier.

Description of drawings:

Fig. 1 starts ballast outward appearance terminals schematic diagram fast for fluorescent lamp.

Fig. 2 starts the ballast circuit schematic diagram fast for fluorescent lamp.

Fig. 3 starts the ballast wiring schematic diagram fast for fluorescent lamp.

With reference to the accompanying drawings, in conjunction with the embodiments the utility model is described in further detail.

A kind of fluorescent lamp starts ballast fast, and cored M, coil, coil have primary coil L ₁With secondary coil L ₂Constitute, coil links to each other with rectifier G, primary coil L ₁D be terminated at the input of rectifier G, secondary coil L ₂B be terminated at "-" utmost point output of rectifier G.Rectifier G selects diode bridge rectifier for use.Primary coil L ₁Two-end-point A, D and rectifier G do not meet primary coil L ₁Another input to draw two terminals B, C be four input terminals of ballast, secondary coil L ₂Two-end-point a, b and "+" utmost point output of rectifier the G two terminals a ', the b ' that draw be four outlet terminals of ballast.

The embodiment ballast has two kinds of band shell and open types.

During use, the input terminal A of ballast connects power supply respectively by a K switch and B end, and starter S is connected to C end, D end; Outlet terminal a, the b of ballast connects fluorescent lamp L one end filament, and fluorescent lamp L other end filament is connected to a ', b ' end.

The utility model has been compared with prior art owing to added the filament heating loop, and fluorescent lamp is worked under direct current and have start fast, starting resistor low (150V still can normally start), the light flicker free does not namely have the advantages such as stroboscopic phenomenon. In addition, this ballast preheat curent is not more than the disconnected head lamp silk of operating current, fluorescent tube and still can uses, and can effectively prolong fluorescent lamp service life.
