Abstract
An electronic starter is characterized in that coils and a voltage-sensitive element Rv of a relay J are connected in series with two ends of connectors (A1 and A2), and contacts of the relay J are connected in series with a diode D2 and then connected to two ends of the connectors (A1 and A2). Its advantages are wide range of working voltage, reliable starting of fluorescent lamp in 160-250V range, no flash, long service life and high starting speed.
Description
The utility model relates to a kind of electronic starter that is used for glow starting fluorescent lamp.
Existing normal starter is the break-make of stretching light modulation preheat curent on controll day of utilizing the thermometal sheet.Need during its work that starting time is long, easily flicker, life-span are short, can't starter when voltage is low.
The purpose of this utility model just provides the electronic starter that a kind of starting time is lacked, do not glimmered, the life-span is long, operating voltage range is wide.
Solution of the present utility model is such: at joint (A1, A2) two ends are serially connected with relay] coil, pressure cell Rv, the contact of relay J with receive joint (A1 after diode D2 also connects, A2) two ends, be connected to capacitor C 1 at relay J coil two ends, at diode D2 two ends and be connected to capacitor C 2, with the said elements device in shell 1, just constitute the utility model, after the fluorescent lamp energized, when joint A1 voltage is timing, not conducting of diode D1, when joint A1 voltage when negative, diode D1 conducting, the positive half cycle of voltage is added to the two ends of pressure cell Rv, when voltage reaches certain value, pressure cell Rv conducting, electric current flows through from the coil of relay J, makes its contact adhesive, diode D2 conducting during the positive half cycle of voltage, capacitor C 2 chargings during negative half period, filament of fluorescent lamp obtains heating.Because diode D2 conducting, at this moment pressure cell Rv two ends pressure reduction reduces, almost no current passes through, the former voltage that is filled with is by the coil discharge of relay J on the capacitor C 1, voltage progressively descends, and makes relay J can't keep adhesive and discharge very soon, and the filament of fluorescent lamp preheat curent is interrupted, since the induced voltage effect of ballast, the fluorescent lamp build-up of luminance.Behind the fluorescent lamp build-up of luminance, the voltage of joint (A1, A2) drops to about 108 volts, and still less than the conduction value of pressure cell Rv, the electric current that therefore flows through the relay J coil is very little for its peak value, and relay J still is in release condition, and fluorescent lamp is kept operate as normal.
The utility model has the advantages that operating voltage range is wide, can reliable glow starting fluorescent lamp in 160v-250v scope, do not glimmer, the life-span is long, starting speed is fast.
Accompanying drawing is embodiment of the present utility model:
Accompanying drawing 1 is circuit theory diagrams.
Accompanying drawing 2 is to be used in the fluorescent lamp electrical schematic diagram.
In the present embodiment, resistance R has been the choked flow effect, and capacitor C 1 has been filtering and time-lag action.Pressure cell Rv adopts piezo-resistance, also can adopt voltage stabilizing didoe.
Claims (4)
1, a kind of electronic starter is characterized in that being serially connected with at joint (A1, A2) two ends coil, the pressure cell Rv of relay J, the contact of relay J and the two ends of also receiving joint (A1, A2) after diode D2 connects.
2, electronic starter according to claim 1 is characterized in that pressure cell Rv can be a piezo-resistance, also can be voltage stabilizing didoe.
