Abstract
The utility model is a kind of operating state that changes conventional fluorescent, and can obviously improve the novel energy-conserving ballast of energy-saving effect.Form by rectification circuit, electric capacity, bleeder resistor, retardation coil.It has effectively overcome poor, the stroboscopic of the startability of existing product, and influence by voltage illumination descends, serious fraud point such as Harmonic Interference, it mainly is made up of bridge rectifier and switching circuit, can under the optimum Working of fluorescent tube, effectively control the input of electric energy, reach purpose of energy saving.And realized not producing second harmonic by starter under the low-voltage, but the very good effect in prolonging lamp tube useful life.
Description
The invention relates to the operating state that changes fluorescent lamp ballast, and can obviously improve a kind of novel florescent lamp Energy-saving ballast of energy-saving effect.
The purpose of inventing this ballast is: effective energy savings, reduce its production cost, and change the operating state of fluorescent lamp ballast to such an extent that more drive in reasonable simple.Especially under the general situation on the low side, can change the disadvantage that original ballast does not start and do not work with voltage at domestic lighting, but and the useful life of prolonging lamp tube, reduce or eliminate humorous high frequency the hindering and damaging of involving to electrical network, communication etc.
This is a synthetic circuit of being made up of full-wave bridge rectifier circuit and multiplication of voltage all-wave start-up circuit.In this circuit, when (220V interchange) after the energized direct voltage about 500V of AB end generation, make lamp tube starting, fluorescent tube enters normal operating conditions thereupon, and both end voltage is reduced to about 110V thereafter.
Its operation principle is: in this circuit, by D

4Form a bridge rectifier.When not connecting load (when lamp does not work), connect the 220V AC power, this moment, circuit A end was negative pole, the B end is for anodal.But owing to incorporate capacitor C in the bridge rectifier
2And C
3, it except normal full-wave rectification function is arranged, the multiplication of voltage of also having had full-wave rectification function.The effect of multiplication of voltage full-wave rectification function is that the startup (being starter) that is used for fluorescent tube is used.We know that the starting resistor of fluorescent tube requires to reach more than the 450V in moment, therefore incorporate C in bridge rectifier into
2And C
3Forming voltage doubling rectifing circuit is easy to start and is provided with for reaching fluorescent tube.
When energized (220V interchange), if this moment, the C point was positive half cycle, then electric current passes through D

3Become loop, at this moment capacitor C

2Two ends have a 240V left and right sides direct voltage to exist, because C

3Two electric capacity are series connection, just C
2And C
3Two direct voltages are additions, so just produce a 500V left and right sides starting resistor at the AB two ends.Can regard the lamp tube ends filament as an end this moment is electron emitter (being negative electrode); The other end is that electron collector (being anode) electronics is flown to by emitter in fluorescent tube that the luminescent substance in the bump fluorescent tube makes lamp tube starting in the process of collector electrode.Fluorescent tube enters operating state thereupon, and the AB both end voltage is reduced to about 100～110 thereafter.Among the figure, C

3Bleeder resistor.Coil L is a choking coil, and the parameter that changes L can be controlled at lamp current under the optimum Working.
This kind ballast than existing ballast (inductance, electronics) have more advantage as:
1, saves copper material more than 40%.Existing inductance type ballast coil windings enamelled wire with φ 0.5～0.6 line directly.And this kind ballast choking coil winding wire diameter is that φ 0.25～0.3 gets final product.Silicon steel sheet amount ratio inductance type is saved more than 20%.
2, working voltage is wide, exchanges 150～240V and all can use.
3, fluorescent tube prolongs several times useful life, and reason is that it need not light filament, and filament only uses as electron emitter and collector electrode.
4, because its operating state is the direct current low frequency, so can not produce higher second harmonic, the IEC standard is 5%, and this kind ballast is 1.4%.
5, owing to do not light filament, therefore bad fluorescent tube (except the lamp tube air leaking etc.) is as long as still can continue the lamp base short circuit to use.
6, economize on electricity more than 20% no stroboscopic.
7, starter must be installed, and one open promptly bright.
The present invention is effective energy savings not only, saves raw material, reduces production costs, and can impel ballast and light fixture manufacturing process that bigger improvement and raising are arranged.
