Abstract

The utility model relates to a durable starter for fluorescent lamps. The base of the durable starter is provided with a midget relay J, a resistor R, a diode D, a capacitor C1 and a capacitor C2. The positive pole of the diode D is connected with a binding post 3, and the negative pole is connected with the resistor R, a midget relay J coil and a binding post 4 in sequence. One end of the normally open contact of the midget relay J is connected with the negative pole of the diode, the other end is connected with the capacitor C1 on the binding post 4 and connected with the midget relay J coil in parallel. The capacitor C2 is in bridge connection with the binding post 3 and the binding post 4. The utility model has the advantages of more than 15 years' long service life, fluorescent tube starting with high efficiency and safety under low voltage and normal work between voltage range of 170V to 240V.

Description

The long-lived starter of fluorescent lamp

The annex that starter is used on a kind of fluorescent lamp.

General starter for fluorescent is to utilize neon bulb can carry out glow discharge under the voltage of the 220v left and right sides, causes bimetal leaf to be heated closure and finishes and start the fluorescent tube function, and its defective is to use the life-span short, generally can only use 1 year; When line voltage is lower than 190v.Forfeiture starts function, causes the fluorescent tube flicker maybe can not light.

The patent No. is that 92235315.8 patents " the fluorescent lamp low-temp low-pressure starter " that propose are though can work under low-temp low-pressure.But still need to use neon bulb, still exist the shortage in useful life to fall into.

The purpose of this utility model provides the long-lived starter of a kind of fluorescent lamp.Accomplish long service life, still can operate as normal under the low-voltage condition.

The purpose of this utility model is achieved in that and is mounted with midget relay J, resistance R, diode D, capacitor C on the base with two binding posts ₁And C ₂, the positive pole of diode D links to each other with a binding post, is serially connected with resistance R, midget relay J coil and another binding post on its negative pole successively.Midget relay J normally opened contact one terminating diode negative pole, the other end are connected on the binding post that links to each other with midget relay J coil, capacitor C ₁With midget relay J coils from parallel connection of coils, capacitor C ₂Be connected across on two binding posts.

Fig. 1 is the long-lived starter structural representation of fluorescent lamp, and 1 is shell among the figure.2 is base, and 3,4 is binding post.

Fig. 2 is the long-lived igniter circuitry schematic diagram of fluorescent lamp, and Q is a fluorescent tube among the figure.

Operation principle is as follows: energized, electric current through ballast L, fluorescent tube Q filament, diode D, resistance R to capacitor C ₁Charging.Work as capacitor C ₁Both end voltage rises when causing electric current by midget relay J coil greater than attract current, midget relay J adhesive.Normally opened contact J ₁Closure makes source current directly through ballast L, diode D, normally opened contact J ₁Fluorescent tube Q filament is carried out preheating.When making electric current by midget relay J coil less than release current owing to the short circuit of normally opened contact, midget relay J discharges, normally opened contact J ₁Disconnect, ballast L produces transient high voltage and lights fluorescent tube Q, and fluorescent tube Q lights its both end voltage of back and quickly falls to below the lamp works voltage 125v, and the electric current of the midget relay J coil that keeps flowing through is less than attract current, be that starter is failure to actuate after fluorescent tube Q lights, guarantee the fluorescent lamp operate as normal.Capacitor C ₂Effect be in order to improve power factor and to suppress high frequency radiation.

Compared with the prior art, the utlity model has and reach service life more than 15 years, low The characteristics of efficient under the voltage conditions, clean boot fluorescent tube, line voltage 170～Fluctuation in the 240v scope, still normal operation.
