Abstract

The utility model discloses an industrial fluorescent lamp ballast, it is mainly established ties through ballast inductance and starter electric capacity, starter inductance to parallelly connected compensation electric capacity and assemble and constitute in the shell in the power supply circuit, simple to operate uses reliably, and is longe-lived, and is energy-conserving, is the necessary renewal product of the large-scale occasion installation fluorescent tube of an ideal.

Description

The industry fluorescent lamp ballast

The utility model relates to the ballast that a kind of fluorescent lighting is used, particularly a kind of ballast that ballast and starter is designed to one with circuit, have waterproof, fire prevention, moisture-proof function, be applicable to that subway, aircraft factory, station, harbour, factories and miness, key state project and family's fluorescent lighting start.

At present, the ballast starter of known fluorescent lamp, mainly contain two types, a kind of is that ballast and starter are used and can work, another kind is an electric ballast newly developed, as two 40 watts of electric ballasts (patent No. is 92202660.2), electronic ballast for high-pressure discharge lamp (patent No. is 92213758.7), transistor stepless dimming ballast (patent No. is 91222419.3), all adopt electronic line structure, preceding a kind of starter easily goes wrong, use inconvenience, a kind of spoilage height in back, the life-span is short, the high-altitude is the change poles inconvenience more, has all brought the trouble of many uses to the user.

The industrial fluorescent lamp ballast that the purpose of this utility model provides a kind of starter and ballast to be integrated, it is made of one by lc circuit, and easy-to-connect is installed, and the life-span is long, and good reliability is energy-conservation, and power factor reaches more than 0.85.

The purpose of this utility model is achieved in that in the iron-clad of standard, capacitor C 1 and power supply 220V be line parallel mutually, electrical network is carried out power factor compensation, inductance L 1 one ends appoint single line to link to each other with power supply 220V ± utmost point, inductance L 1 other end is connected with capacitor C 2, inductance L 2 by fluorescent tube, link to each other with power supply 220V ± utmost point any wire by the fluorescent tube other end again, like this, design of the present utility model has just been finished.When using, the power supply power supply, L1, C1, L2 phase shift by the filament series resonance of fluorescent tube, produce 420-500V voltage lamp tube starting, and behind the lamp tube starting, L1 plays the ballast effect to fluorescent tube, and the internal resistance of fluorescent tube is less than L2 and C2.L2 and C2 also have certain compensating action to fluorescent tube.

Owing to adopted the technical solution of the utility model, reduced starter, only adopt inductance, capacity cell to replace, ballast and starter are integrated, the components and parts that adopt in the entire circuit are still inductance durable in the original Inductive ballast, but because of design innovation, the utility model has been realized electric network active rate factor is compensated, have economize on electricity, low-voltage starter, the advantage of long service life.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is circuit theory diagrams of the present utility model.

Wiring schematic diagram when Fig. 2 uses for the utility model.

Dash number in the accompanying drawing is power line (1), shell (2), building-out capacitor C1 (3), ballast inductance L1 (4), starter inductance L 2 (5), starting capacitor C2 (6), fluorescent tube one end connecting line (7), fluorescent tube other end connecting line (8), shell bottom plate (9).

With reference to Fig. 1, Fig. 2,, power line (1) 220V phase line shunt compensation capacitor C 1 (3), ballast inductance L1 (4) one ends and power supply 220V ± extremely arbitrary linking, the other end is connected with build-up of luminance capacitor C 2 (6), build-up of luminance inductance L 2 (5) by fluorescent tube one end connecting line (7), form the loop by fluorescent tube other end connecting line (8) and power supply 220V ± extremely arbitrary linking again, after being assembled into one, embedding insulation filling material, then shell (2) is loaded onto, refill shell bottom plate (9), promptly finished making of the present utility model.

During use, with reference to Fig. 2, the utility model is connected with the mains, fluorescent tube one end connecting line (7) and fluorescent tube other end connecting line (8) are connected with fluorescent tube and got final product, and be easy for installation, uses reliable.

Claims (1)

1, a kind of fluorescent lamp ballast of forming by shell and dress inductance within it, it is characterized in that in power supply 220V phase line, being parallel with capacitor C 1, ballast inductance L1 connects with build-up of luminance capacitor C 2, build-up of luminance inductance L 2 by the filament of fluorescent tube, forms the loop by the filament of fluorescent tube again and constitutes.
