Abstract

The utility model relates to an energy-saving compensator for a fluorescent lamp. The utility model is characterized in that a series resonant circuit composed of an inductance element L and a capacitance element C is connected in series in a fluorescent lamp filament circuit. The utility model can replace original fluorescent lamp starter to achieve once glow starting ignition without bouncing when meeting the condition of the fluorescent lamp glow starting ignition, which can save electrical energy and prolong the service life of a fluorescent tube and a compensator.

Description

Energy-saving compensater for fluorescent lamp

The utility model relates to fluorescent lamp starter device, a kind of energy-conservation compensator that is used for substituting original fluorescence lamp starter of more specifically saying so.

At present, for the fluorescent lamp that adopts inductance type ballast, all be that series connection inserts starter in filament loop.But,, not only cause waste of electric energy, and be restricted the useful life of starter itself owing in the starter process a bigger short circuit current is arranged.The frequent damage of starter brings problems such as use cost increase, maintenance capacity increasing.In addition, the repeatedly spring in the starter process makes the fluorescent tube negative electrode very easily impaired aging, greatly influences the useful life of fluorescent tube.Experiment showed, that the every spring of fluorescent lamp once was equivalent to use two hours.

The purpose of this utility model is to avoid the deficiencies in the prior art part, provides a kind of fluorescent lamp energy-conservation compensator, to substitute original fluorescence lamp starter.When satisfying the fluorescent lamp starter and lighting condition, reach disposable starter and light, with saves energy, prolong useful life of fluorescent lamp tube and compensator itself.

The purpose of this utility model realizes by following technical solution.

The utility model constitutes series resonant circuit by inductance element and capacity cell, and this series resonant circuit is connected in series in the Filament of fluorescent lamp loop, replaces former fluorescence lamp starter.

Compared with the prior art, the utlity model has following advantage.

1, in the utility model starter process, spring is lighted, do not had to disposable starter.When supply voltage is 220V ± 10%, starting time≤0.4 second.Prolonged the useful life of fluorescent tube.

2, use the utility model can improve power factor, improve grid voltage waveform, saves energy.

3, simple in structure, the dependable performance of the utility model, long service life.After the original starter of cancellation, can save use cost, reduce maintenance load.

4, the utlity model has automatic compensation function, when line voltage is too high or too low, all can make fluorescent tube luminous stable.

Fig. 1 is the utility model circuit theory diagrams.

Fig. 2 is the wiring schematic diagram of the utility model in filament loop.

Number in the figure: 1, compensator, 2, fluorescent tube, 3, ballast.

By the following examples, in conjunction with the accompanying drawings, the utility model is further described.

Embodiment:

Referring to accompanying drawing, compensator 1 replaces traditional fluorescence lamp starter, is connected in series in the filament loop of fluorescent lamp.Compensator 1 is to constitute series resonant circuit by inductance component L and capacity cell C, wherein inductive reactance xl=capacitive reactance XC.Energized instantaneous, fluorescent tube 2 presents high-impedance state, since XL=XC, circuit resonance.Under capacitor C charge and discharge effect, between the negative electrode of fluorescent tube 2, form starting voltage.In case starting voltage is set up, the current point pipe of lighting a lamp is arranged promptly; Behind the starter, fluorescent tube presents low resistive state, and resonance disappears, and the loop is the operating state of soft resonance.Fluorescent tube 2 constitutes loops with ballast 3, two cathode stabilization under 108～120V voltage, fluorescent tube 2 normal luminous work.

Claims (1)

1, the energy-conservation compensator of a kind of fluorescent lamp is characterized in that constituting series resonant circuit by inductance component L and capacity cell C, and described series resonant circuit is connected in series in the Filament of fluorescent lamp loop.
