Description

Ignition device for incandescent lamp

The utility model belongs to lighting technical field, relates in particular to a kind of apparatus for igniting fulorescent lamp that adopts electronic circuit to combine with inductance.

Existing ballast of fluorescent lamp owing to start by starter, serious stroboscopic often occurs, when voltage hangs down, starts very difficultly, greatly affects service life of fluorescent lamp; Though and electric ballast improves Inductive ballast, replace Inductive ballast to open soon power savings advantage, because it can not current limliting and zero load, the shortcomings such as power factor is low, cause itself low in service life, easily burn fluorescent tube, make energy-conservation applying be subjected to certain limitation.

The purpose of this utility model is to overcome deficiency of the prior art and proposes a kind of apparatus for igniting fulorescent lamp, the employing high voltage direct current starts, and current limit by inductance reaches the purpose that opens durable energy saving soon, in the useful life of prolonging lamp tube, make the fluorescent lamp also can operate as normal under low-voltage state.

The purpose of this utility model is such realization: a kind of apparatus for igniting fulorescent lamp, by the unilateal conduction effect of diode and the effect that discharges and recharges of electric capacity, to capacitor charging, and generation electrion, resistance by inductance exchanges perfectly straight stream effect, the instantaneous generation HVDC of fluorescent tube is started, and inductance plays again metering function after starting; Capacitor C wherein ₁With diode D ₁Series connection is same capacitor C again ₂With diode D ₂Series circuit form relation in parallel; D ₁Conducting, C ₁Charging; D ₂Conducting, C ₂Charging; And exchanging perfectly straight stream effect by the limit of inductance, instantaneous generation HVDC pressurizes to lamp tube ends, makes fluorescent tube produce electric arc, the glimmering powder generation daylight that is stimulated.

The utlity model has low-voltage and start, without starter, one opens promptly brightly, starts no stroboscopic, has the function of vision protection and elimination eyes muscular fatigue; It is wide to adapt to voltage range, normally starts at 130V__250V, at 100V _～Operate as normal in the 280V has prolonged useful life of fluorescent tube, be a times of Inductive ballast fluorescent lamp, and old fluorescent tube needs only air tight reusing; Power savings is remarkable, than Inductive ballast economize on electricity 51%, than electric ballast economize on electricity 10__20%, and itself in life-span all improve greatly than preceding two kinds.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a circuit structure diagram of the present utility model.

As shown in Figure 1, the utility model is by capacitor C ₁With diode D ₁After the series connection again with capacitor C ₂With diode D ₂Series circuit parallel connection, parallel circuit two ends 1,2 add power supply voltage 220V, along with the variation of alternating current, and when 2 ends are positive pole, D ₁C is given in conducting ₁Charging; When 1 end is positive pole, D ₂C is given in conducting ₂Charging; D ₁D ₂Play unilateal conduction and charging rectifier effect, to improve the voltage on two electric capacity; In capacitor C ₁C ₂Output is drawn at the discharge circuit two ends that form again, and 4 is output cathode, and 3 is output negative pole, and the effect of inductance L is instantaneous raising voltage, and resistance exchanges perfectly straight stream; Behind the plugged, by output 4 output HIGH voltage direct currents, by inductance L connecting tube 7 one ends 6, electron emission, filament produce electric arc under action of high voltage, fluorescent material is stimulated by mercuryvapour launches daylight; The fluorescent tube other end 5 receives electronics, and connects with electric capacity output negative pole 3, forms the loop, and energising produces clean electricity after resistance R, connect by 8 ends and lamp bracket, and low-voltage can be started fast; During line, will have the lamp tube ends crosspointer now and merge into a pin, connect with output both positive and negative polarity of the present utility model again.

Claims (1)

1, a kind of apparatus for igniting fulorescent lamp is interconnected and is formed by capacitor C, inductance L, resistance R, diode D, it is characterized in that: with capacitor C ₁With diode D ₁Same capacitor C again after the series connection ₂With diode D ₂The series circuit parallel connection, circuit two ends 1,2 in parallel add power supply voltage 220V, again from C ₁C ₂The discharge circuit that forms is drawn output cathode 4 and output negative pole 3, after output cathode 4 connects with inductance L again, links to each other with fluorescent tube 7 one ends 6, and the fluorescent tube other end 5 connects output negative poles 3, forms the loop, and the clean electricity of generation is abutted against 8 by 9 ends through resistance R and connects with lamp bracket.
