Abstract

The invention discloses a fluorescent tube ballast formed by combining a capacitor with a self-coupling boost transformer. According to the invention, the fluorescent tube ballast can rapidly start up the fluorescent tube ballast without filament preheating, the brightness is enough, and the fluorescent tube ballast can save more energies than an inductive ballast.

Description

A kind of fluorescent tube ballast

Technical field

Fluorescent lamp ballast

Background technology

Main illuminating lamp kind fluorescent lamp after incandescent lighting still accounts for the main status of illuminating industry all the time up till now, now remain the deal of in illuminating lamp kind about 2/3rds, the appearance of high-efficiency energy-saving LED lamp likely replaces the illumination of other lamp kinds later completely, but still cannot replace fluorescent lamp completely up till now, chief reason is that price is high, technology there also is not full maturity also not reach the inexpensive degree of user's requirement, so the stage that illumination history is exited in the illumination of fluorescent lamp completely also will treat the regular hour.

Current fluorescent lamp is lighted illumination and is mainly realized by two kinds of methods: a kind of is the most original Inductive ballast, and another kind is the electric ballast with progressive; But the advantages such as all also have certain defect in the middle of these two kinds of ballasts, Inductive ballast is that to have the life-span long, and brightness is enough, but defect is not too energy-conservation, and starting time is slow, is attached with starter; Electric ballast is more energy-conservation than Inductive ballast, but easily damages.

In order to solve the defect of the supporting original paper ballast of the fluorescent lamp lighting be in great demand in addition at present, I am very long in the life-span, and the Inductive ballast that brightness is enough is improved, and object improves above shortcoming existing for two kinds of ballasts.

Summary of the invention

A kind of fluorescent tube ballast, its feature: the self coupling step-up transformer being coiled into two groups of coils on iron core-closed, the multi-thread footpath of the number of turns of step-up coil is little, the few wire diameter of wire circle connecing power supply is thick, two coils around originating party to identical, the end of step-up coil is connected with the top of power coil, a wiring is exported at tie point, the polarity free capacitor of wiring again with one appropriate capacity is connected, the other end of electric capacity and the other end of power coil connect 220V AC power, fluorescent tube is the top receiving step-up coil, other end receives that one end that electric capacity connects power supply.

When the power supply winding coil of a series connection electric capacity received by 220V alternating current, in the induction of step-up coil, generate a high voltage lead to fluorescent tube, the electric capacity be meanwhile connected on the centre cap of the tie point of two coils also produces voltage superposition that the direction of sparking potential and step-up coil produce and generates a higher pulse voltage and lighted fluorescent tube, when fluorescent tube starter is lighted normally, all voltage drops are just born by the electric capacity be serially connected in two coil tie points, thus ensure that the normal work of fluorescent tube.

This spline structure is simple, starts fast ballast and just can instead of former Inductive ballast to employ.And higher than Inductive ballast efficiency, energy-conservation, eliminate original starter again, the life-span is long, durable.

Accompanying drawing illustrates:

Fig. 1 is the wiring block diagram of fluorescent lamp and ballast;

Fig. 2 is this ballast circuit figure.

Embodiment

A step-up transformer is coiled into coil, and the winding direction of two coils is identical, a top of two coils is connected with the end of another, junction wire picks out a centre cap, centre cap is connected an electric capacity again, just form a sight lamp ballast that can start fast, because this town ballast is formed by electric capacity and inductor combination, the capacity of its electric capacity and the number of turns inductance value of transformer are not fixing values, they can capacitance more greatly, and inductance value is few, also can lack by capacitance, and strengthen inductance value, so now can only provide a structure line map reference value, structure line map is as accompanying drawing, reference value is the ratio of step-up transformer, and to be 220:12 be exactly that high-tension coil receives the handing-over electricity that 220V AC power low-voltage coil can export 12V.Because the wattage of fluorescent lamp is also not of uniform size, so the power of transformer is probably chosen between 3W to 10W, capacitance is also choose between 1uf to 5uf.But the withstand voltage of electric capacity will at more than 400V.

Claims

1. a fluorescent tube ballast, its feature: the self coupling step-up transformer being coiled into two groups of coils on iron core-closed, the multi-thread footpath of the number of turns of step-up coil is little, the few wire diameter of wire circle connecing power supply is thick, two coils around originating party to identical, the end of step-up coil is connected with the top of power coil, a wiring is exported at tie point, the polarity free capacitor of wiring again with one appropriate capacity is connected, the other end of electric capacity and the other end of power coil connect 220V AC power, fluorescent tube is the top receiving step-up coil, other end receives that one end that electric capacity connects power supply.
