Abstract
The utility model relates to a fluorescent lamp ballast, particularly a capacitor inductor type ballast. The capacitor inductor type ballast is formed by the connection of an inductor and a capacitor. The capacitor inductor type ballast is characterized in that the inductor is formed by the connection in series of an inductor L1, an inductor L2, and an inductor L3; one end of the inductor L1 is communicated with one end of an AC input terminal, and the other end of the inductor L1 and a joint of the inductor L2 are connected to one end of the capacitor; the other end of the capacitor and the AC input terminal form a connection in series loop through filaments on one end of a fluorescent lamp tube; the joints of the inductor L2 and the inductor L3 and the other end of the L3 form a connection in series loop through filaments on the other end of the fluorescent lamp tube. The utility model has the advantages of safety, high durability, electricity saving, high efficiency, low manufacturing cost, and long service life.
Description
The utility model belongs to fluorescent lamp ballast, particularly about a kind of appearance sense formula ballast.
Known Inductive ballast, though experience all sorts of durablely, the life-span is long, and is noiseless to radio, its power consumption is big; Though the outfit starter can not start at once.If it is on the low side to run into voltage, more be difficult to start and work.And electric ballast, although low energy, the disposable startup of energy, wide voltage power supply, its deadly defect is that main electric elements burn easily, the life-span is difficult to guarantee.So electric ballast economizes on electricity again, not only do not save money but also trouble as reliability is low.
The purpose of this utility model provides the ballast of a kind of not only safety durable but also electricity-saving high efficiency, and production cost is low, long service life.
The technical solution of the utility model is: it comprises that inductance, electric capacity constitute, it is characterized in that: inductance is composed in series by inductance L 1, inductance L 2, inductance L 3, inductance L 1 one ends are communicated with an end of ac input end, the other end is connected electric capacity one end with the joint of inductance L 2, the other end of electric capacity and ac input end constitute series loop by the filament of fluorescent tube one end, and the joint of inductance L 2 and inductance L 3 and the other end of L3 constitute series loop by the other end filament of fluorescent tube.
Product of the present utility model with the pure inductance ballast with the characteristics of comparing with electric ballast is:
1, the pure inductance ballast starts the raising starting resistor by starter, and product of the present utility model is to improve the voltage one-shot.Start back pure inductance ballast tube wall fluorescence and make conductor and form the loop, product fluorescent tube of the present utility model both sides filament all is provided with the loop, and stature both end voltage balance, but both prolonging lamp tube service life can guarantee that again circuit is stable.
2, electric ballast uses at limiting edge for reducing the material cost device parameters because the cost height, so damage easily when big or fluorescent tube is old and feeble in voltage fluctuation.And product required device of the present utility model is few, and used device parameters is much larger than the parameter of normal use, thus in practicality not can because of the fluctuation of voltage or fluorescent tube aging cause damage and also cost low.
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
Accompanying drawing 1 is the embodiment electrical block diagram.
Among the figure: 1, inductance; 2, electric capacity; 3, fluorescent lamp; 4, filament.
Inductance 1 is composed in series by inductance L 1, inductance L 2, inductance L 3, inductance L 1 one ends are communicated with an end of ac input end, the other end is connected electric capacity 2 one ends with inductance L 1 with the joint of inductance L 2, the other end of electric capacity 2 is held filament 4 with the A that ac input end connects fluorescent tube 3, inductance L 2 connects the B end of fluorescent tube 3 with the joint of inductance L 3 and the other end of L3, and forms the polyphone loops with B end filament 4.
In the circuit that inductance and electric capacity are arranged, the voltage of induction reactance always is ahead of electric current 90 degree, and the voltage delay of capacitive reactance is in electric current 90 degree.
During startup, electric capacity 2 compensates, and with the induction reactance formation 50MZ in inductance 1 coil, 600～800V voltage is lighted inner fluorescent tube, makes lamp luminescence.Owing to the compensation of electric capacity 2 is arranged, so when low-voltage, can start in the same old way.
After the lamp luminescence, the anti-and capacitive reactance of the electric current inductance in the circuit suppresses mutually, so the electric current in the circuit is in stable state all the time, and in order to economize on electricity, the electric current in the circuit is no more than 300mA, than pure inductance circuit economize on electricity 30%.Inductance value is controlled at 2～2.2 henries, and electric capacity 2 is controlled at 3～5 μ F, and line is through adopting 0.25～0.47 to satisfy the 300mA electric current fully, and ac voltage withstanding is at 600～1000 volts.
This product on the make material therefor all stream abundant surplus is arranged, the logicality of circuit is good in addition, so, even frequently use or long-time use still keeps the long-life.
