Abstract
The utility model relates to a multifunction fluorescent lamp ballast used for the start-up and light of a fluorescent lamp, composed of an inductance and capacitors. A ballast coil L1 connected with a low voltage lighting coil L2 in series is connected with one end of a lamp tube, a filament heating coil n is connected with the filament of one end of the lamp tube, both heads of the filament are connected with one end of capacitors C1 and C2. The utility model has the advantages of high reliability, low proper loss, etc., not only can directly start in a low voltage, but also can regulate light, as well as can be used for a single tube to work, and can also be used for multi-tubes to work.
Description
The utility model is a kind of multi-functional fluorescent lamp ballasting device that is used for various fluorescent lamp startings and lights, and belongs to the electric lighting technical field.
Existing fluorescent lamp ballast has inductance type ballast and electric ballast two classes.Inductance type ballast is simple in structure, but needs usually just can make the fluorescent lamp operate as normal with the starter cooperation, often is difficult to start when voltage is low, particularly winter, makes troubles to the user.Electric ballast has low voltage starting and does not need the characteristics of starter, but generally electric ballast all has high order harmonic component and causes electronic pollution, influences the electrical network waveform, and the cost height, and reliability is relatively poor, thereby is difficult to generally promote.
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of starter that do not need to start the multi-functional fluorescent lamp ballasting device of lighting with regard to the direct low pressure of energy, and reliable operation, no electronic pollution, and cost is low.
The utility model is made up of inductance and electric capacity, and its characteristics are inductance B
1By ballast coil L
1, low pressure lights coil L
2Constitute L with filament heater coil n
1And L
2The series connection back is connected with an end of fluorescent tube, and n is connected capacitor C with the filament of fluorescent tube one end
1And C
2An end and L
1And L
2Link link to each other C
1And C
2The other end be connected with filament two of the fluorescent tube other end respectively.When the power turn-on switch, fluorescent tube is unlit moment still, and device work is in the humorous formula transformer state of string, coil L
1And L
2Produce high voltage for self coupling boosts, coil n produces the filament heating current of fluorescent tube, and two kinds of effects are lighted fluorescent tube very soon, approach one open promptly bright; After fluorescent tube is lighted, device automatically is transformed into limited current state (promptly also humorous choked flow hold concurrently current transformer) immediately, and the filament that continues as fluorescent tube provides heating current, and overcurrent does not diminish, its phase place is also inconsistent with lamp current, and the opposite end voltage over zero repeats to light effect very much.Capacitor C
1, C
2For adjusting the usefulness of electric current proportioning.In order to make device have dimming function, coil L
2Adopt tapped coil, and be connected with each tap, so that realize the requirement of different brightness by the light modulation selector switch; Enlarge dimming scope if desired, can set up a tapped coil L
3, L
3An end and L
2Series connection, the other end is connected with the light modulation selector switch.In order to make device can be used to light many fluorescent tubes, the filament heater coil can have a plurality of coils to constitute, for example n
1, n
2, n
3, n
4, promptly 1~4.
The utility model compared with prior art, have advantages such as reliability height, cost is low and power factor (PF) is high, own loss is low, do not need starter just can directly start, and can under the lower situation of voltage, light, both can be used for single tube work, also can be used for multitube work, also can realize light modulation, old fluorescent tube helps prolonging lamp tube service life, even also can utilize.
Fig. 1 is the structural representation that is used for single tube work; Fig. 2 is used for the structural representation that four plumbers do.
The utility model can take scheme shown in the drawings to realize.The ballast device that is used for single tube as shown in Figure 1, U
0Be 220 volts of AC power, K
1Be mains switch, fluorescent tube D is the 40W fluorescent lamp, coil L
1And L
2Series inductance increases by 10~20% than common ballast, C
1And C
2Total capacity be 3~4 microfarads, coil n can get L
15~10%.The ballast device that is used for multitube can adopt scheme shown in Figure 2, D
1, D
2, D
3, D
4Can be four 20W fluorescent lamps, L
1And L
2Series inductance increases by 40~60% than common ballast, B
2Be the light modulation inductance, its coil inductance L
3Can design K according to the scope of light modulation
2Be the light modulation selector switch, can adopt wave band formula switch, C
1And C
2Total capacity can be 5~6 microfarads, n
1, n
2, n
3And n
4Inductance value can get L
15~10%, U
0Be 220 volts of AC power, K
1Be mains switch.
