Abstract

The utility model relates to a glow-starting ballast for a fluorescent lamp. Comprising an iron core (silicon steel sheet) wound with two coils or a ferrite core (ferrite core) and an electric condenser, wherein, one coil has the current limiting action, and the other coil and the electric condenser are connected in series having the glow-starting and automatic voltage regulation actions. The utility model has the advantages of fast starting, noiselessness, big luminous flux, saving energy by 50 %, extending the service life of a lamp tube, not having influence on an electric network, wide starting voltage range (85-220 v) and starting service voltage range (65-220 v), etc.

Description

Glow-starting ballast

The utility model relates to a kind of fluorescent tube starter ballast device.

At present, the ballast of selling on the market mainly contains two kinds of electronic type and inductance types, the shortcoming of inductance type ballast is that starting resistor scope and operating voltage range are too little, electronic ballast adopts diode multiplication of voltage ballast, saved starter, but its life-span is not long, and luminous flux is not enough, and fluorescent tube is had certain infringement.

The purpose of this utility model is a kind of long service life of design, the starter ballast device that has starter and ballast double action simultaneously.

Its technical solution is: the starter ballast device is made up of an iron core (silicon steel sheet) that is wound with two coils or ferrite core (ferrite core) and a capacitor, insert fluorescent tube after one of them coil and the capacitors in series, another coil one termination is gone into power supply, and the other end inserts fluorescent tube.

The utility model has the advantages that: start fast, one open promptly bright, but preheating (1-3 second) is arranged, do not have the process of flashing, operating voltage range (65-220V) and starting resistor scope (85-220V) are wide, noiselessness, luminous flux is big, energy-conservation 50%, electrical network there is not influence, temperature, humidity do not have influence to starting.

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is the utility model outside drawing;

Fig. 2 is the utility model circuit theory diagrams.

Fluorescent tube 3 is inserted in capacitor C and coil 1 series connection back, and coil 2 one terminations are gone into power supply, and the other end inserts fluorescent tube 3, and behind power connection, electric current carries out preheating through coil 2, filament, coil 1, capacitor C and the filament of starter ballast device to filament.Because 90 ° of the voltage leading currents at coil 1 two ends, capacitor C both end voltage lags behind 90 ° in electric current again, and two voltages add together altogether about 410V, enough light fluorescent tube 3.After the starting, 2 metering functions of coil, coil 1 and capacitor C play the automatic Regulation effect.Capacitor C parameter is about 2.4 μ F.According to the fluorescent tube of different capacity, mix the starter ballast device of corresponding power respectively.

Claims

1, a kind of fluorescent lamp starter ballast device, it is characterized in that forming by an iron core (silicon steel sheet) that is wound with two coils or ferrite core (ferrite core) and a capacitor, one of them coil one termination power, the other end inserts fluorescent tube, inserts fluorescent tube after another coil and the capacitors in series.
