Abstract
The utility model discloses a ballast for a fluorescent light, which is composed of an inductor coil and a capacitor. The utility model can be quickly started under the condition of low voltage without a starter, and is an ideal product for replacing an old type ballast.
Description
The utility model relates to a kind of fluorescent lamp ballast.
Fluorescent lamp ballast in the market is a lot, inductance type arranged with electronic type, but all exist starting difficulty, problem such as low-voltage can't start, and is fragile is not so to use also be so desirable to the fluorescent lamp ballast on the market now.
The purpose of this utility model designs a kind of low cost that has exactly, starts well under low voltage conditions, and the life-span is long, and does not need the daylight ballast for lamp of supporting use starter again.
The utility model adopts following design to realize: be connected in series by three inductance coils and form inductor, be connected to a capacitor C at the serial connection place of inductance coil L1 and L2, its mode of connection is such, one end of the unsettled termination 220V power supply of inductance coil L1, terminals of unsettled termination fluorescent tube one end of capacitor C, the other end of another wiring termination 220V power supply of this end filament.The terminals that a line connects fluorescent tube other end filament are drawn at the serial connection place of inductance coil L2 and L3, another terminals of this end filament of unsettled termination of inductance coil L3.
Its operation principle is such: the series circuit of being made up of inductance coil L1 and capacitor C is in the moment of energized, and L1 produces a higher induced voltage capacitor C is charged, and the glower end that is connected with electric capacity just has electric current to flow through, and makes the fluorescent tube preheating and starts.The circuit of L2 and L3 composition produces induced voltage to the power supply of other end filament simultaneously, and starts fluorescent tube.After fluorescent tube started, the serial resonant circuit of being made up of L2 and C provided supply current to fluorescent tube.
The design's advantage just is to guarantee that fluorescent tube starts fast under low voltage conditions, and does not need to connect in addition starter again, and cost is low.
Further specify the utility model below with reference to the accompanying drawings.
Accompanying drawing is the electrical schematic diagram and the winding diagram of ballast
L1, L2 and L3 are composed in series inductor, serial connection place at L1 and L2 is connected to capacitor C, the filament terminals of unsettled termination fluorescent tube one end of capacitor C, terminals of the unsettled termination 220V power supply of coil L1, another terminals of another filament wiring termination 220V power supply of this end fluorescent tube.The filament terminals that the serial connection place of inductance coil L2 and L3 is connected to the other end of a wiring and fluorescent tube link, and the free end of L3 is connected with another terminals of this end filament.
Claims (1)
- A kind of fluorescent lamp ballast, form by inductor and electric capacity, it is characterized in that: inductor is composed in series by coil L1, L2, L3, serial connection place at L1 and L2 is connected to capacitor C, another terminals of capacitor C are connected with the filament terminals of fluorescent lamp, another termination 220V power end of inductance coil L1, there is a lead-out wire to connect an end of tube filament, another terminals of the unsettled termination filament of inductance coil L3 at the serial connection place of inductance coil L2 and L3.
