Abstract
The utility model relates to a starter of fluorescent lamps, which comprises a rectification power supply (1), which is characterized in that the output end of the rectification power supply (1) is connected with a starting relay J, a capacitor is connected in parallel with the two ends of the starting relay J, and the normally open contact K of the starting relay is connected in parallel with the rectification power supply (1). The present starter starts rapidly and works reliably, and no multiple flashes occur when fluorescent lamps are started, prolonging the service life of fluorescent lamp tubes. The structure of the starter is relatively simple and durable.
Description
Technical field
The utility model relates to a kind of starter for fluorescent.
Background technology
At present, when using the fluorescent lamp system of inductance oscillator, generally adopt neon bulb starter to light fluorescent tube, but this starter has following shortcoming: when one, this starter feeding electric current, need a period of time to heat to sheet metal, therefore, its start-up time is longer.When starting fluorescent lamp during two, owing to this starter, cause the repeatedly flicker of fluorescent tube, thereby make the lost of life of fluorescent tube.Three,, burnt easily in the use, so traditional starter is shorter useful life because the bimetal leaf in this starter is extremely thin.
Technology constitutes
The utility model is in order to overcome above-mentioned shortcoming, provides that a kind of good reliability, starter are fast, the starter of the startup fluorescent tube of long service life.
The utility model is to realize like this.It comprises a rectifier power source, and the output termination starter relay of this rectifier power source is parallel with capacitor C at the two ends of starter relay, the normally open contact of starter relay and the rectifier power source formation that is in parallel.
Its operation principle is: when fluorescent lamp rigidly connected energize, the lamp tube ends filament resistance was very little, and powerful electric current reaches starter by the starter filament, and be full of electricity for starter electric capacity, simultaneously, make the relay contact contact, make the starter short circuit, at this moment, the starter filament spot.Because starter is short circuit, electric capacity can't charge.When capacitance voltage was very little, relay contact disconnected, at this moment lamp tube starting.The resistance of starter filament strengthens thereupon, and starter still can't charge to electric capacity, and at this moment, startup finishes, if but this moment fluorescent tube do not have or not exclusively light, so, the electric current of starter increases once more, and to capacitor charging, starter once more ....
Because the utility model adopts the starter of starter fluorescent tube of the principle design of relay, not only start rapidly, reliable operation, and repeatedly glimmer when fluorescent tube is started, can prolong the useful life of fluorescent tube.This starter structure is also fairly simple, and is durable.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
Execution mode
The said rectifier power source 1 of the utility model can adopt any of half-wave, all-wave or bridge rectifier.The output termination starter relay J of rectifier power source 1, capacitor C in parallel at the two ends of starter relay J, the normally open contact K of starter relay J and rectifier power source 1 formation that is in parallel.
In order to regulate the start-up time of this starter, in the two ends of capacitor C capacitor C 1 in parallel, and one many grades speed-regulating switch K1 of series connection, at this moment, the starter relay J is connected with a shelves of many grades of speed-regulating switch K1 with the parallel circuits that D2, D4 constitute through diode D1, D5; The starter relay J is connected with the b shelves of many grades of speed-regulating switch K1 through the series circuit that diode D2, D6 constitute; The starter relay J is connected with the e shelves of many grades of speed-regulating switch K1 through the series circuit that diode D1, D3 constitute.The negative pole of capacitor C is connected between diode D2, the D6; The negative pole of capacitor C 1 is connected between diode D1, the D3 and constitutes.
Claims (2)
1, relay starter, it comprises a rectifier power source (1), it is characterized in that: the output termination starter relay J of this rectifier power source (1) is parallel with capacitor C at the two ends of starter relay J, the normally open contact K of starter relay and rectifier power source (1) formation that is in parallel.
2, relay starter according to claim 1, it is characterized in that: in the two ends of capacitor C capacitor C 1 in parallel, one the many grades speed-regulating switch K1 that connect, the starter relay J is connected with a shelves of many grades of speed-regulating switch K1 through the parallel circuits that diode D1, D5 and D2, D4 constitute; Wherein, the starter relay J is connected with the b shelves of many grades of speed-regulating switch K1 through the series circuit that diode D2, D6 constitute; The starter relay J is connected with the e shelves of many grades of speed-regulating switch K1 through the series circuit that diode D1, D3 constitute; The negative pole of capacitor C is connected between diode D2, the D6; The negative pole of capacitor C 1 is connected between diode D1, the D3 and constitutes.
