Abstract

The utility model relates to a capacitor ignitor for fluorescent lamps. The starting is controlled by a contact of a relay and is formed by having a starting bypass and a relay coil power supply bypass connected in series. Current-limiting resistances are connected in series with a relay coil, which enables fluorescent lamps to be lightened in a single time without twinkling and further lengthens the service life of fluorescent tubes.

Description

Fluorescent lamp condenser type starter

The utility model relates to a kind of starter for fluorescent, especially a kind of fluorescent lamp condenser type starter.

Use the daylight lamp circuit of inductance type ballast must use starter to make tube starting luminous, traditional bimetal leaf starter since during starter fluorescent tube need flash several times could be normally luminous, can make fluorescent tube shortening in useful life, and the contact of bimetal leaf is more fragile, and influence is normally used.

The purpose of this utility model provides a kind of fluorescent tube that can prolong can make the fluorescent lamp fast starting again useful life, and non-damageable fluorescent lamp condenser type starter.

In order to achieve the above object, the utility model fluorescent lamp condenser type starter adopts relay contact control starter, and it is to be formed in parallel by starter branch road and relay coil power supply branch road, it is characterized in that described starter props up the normally opened contact formation of route relay; A relay coil power supply route rectifier diode, piezo-resistance, relay coil serial connection form, and are parallel with a delay capacitor at the two ends of relay coil.

The utility model fluorescent lamp condenser type starter is current-limiting resistance of serial connection on relay coil also, and the big I of adjusting this resistance changes the time that filament of fluorescent lamp adds electric preheating.

The utility model adopts relay contact to trigger starter, and more durable than bimetal leaf starter, warm-up time is abundant, and starter of fluorescent tube is lighted, and does not have scintillation, has prolonged the useful life of fluorescent tube.

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

Fig. 1 is the circuit theory diagrams of the utility model fluorescent lamp condenser type starter.

In Fig. 1, A, B are two tie points of starter and daylight lamp circuit, between two tie points of A, B and be connected with starter branch road and relay coil power supply branch road.The starter branch road is the normally opened contact J by relay _KForm, two contacts directly are parallel between A, B, relay coil power supply route rectifier diode D, piezo-resistance R ₁, current-limiting resistance R ₂J is in series with relay coil, at relay coil J and current-limiting resistance R ₂Be parallel with delay capacitor C on two outer point of serial connection.

The course of work of the present utility model is as follows: closed daylight lamp power source K switch, 220 volts of civil powers are added on two end points of A, B of starter through the filament of ballast L and fluorescent tube H, because this moment, fluorescent tube H end starter was lighted, line voltage almost all is added between A, B two-end-point, makes piezo-resistance R behind diode rectification D ₁Puncture conducting, to delay capacitor C charging, the voltage on the capacitor C raises gradually, and when this voltage was elevated to the pick-up voltage of relay, normally opened contact J was connected in the relay adhesive _K2 of A, B are switched on, filament of fluorescent lamp is powered preheating, this moment, relay coil J kept adhesive by delay capacitor C discharge, keep voltage when following up to what capacitor C both end voltage dropped to relay, the tripping of relay decompression disconnects the starter branch road, and ballast L produces instantaneous high pressure lights starter of the enough fluorescent tube H of preheating.The time of fluorescent tube preheating is by capacity and the resistance R of capacitor C ₂Resistance decision, suitably choose capacity and the resistance R of capacitor C ₂Resistance can make the fluorescent lamp can a luminous time that as far as possible reduces the fluorescent tube preheating again of starter.

Its both end voltage of the normal luminous back of tube starting reduces, and A, B two-end-point voltage are lower than piezo-resistance R ₁Puncture voltage, after rectifier diode D rectification, can not puncture pressure-sensitive resistance R ₁, relay coil power supply branch road is in off-state, makes fluorescent tube keep normally luminous.
