Description
Technical field
The utility model relates to the energy-saving illumination technical field, refers to especially a kind of ballast, especially a kind of intelligent chip frequency converting and preheating type electric ballast.
Background technology
Ballast is the equipment that plays metering function on fluorescent lamp and produce instantaneous pressure, it is to twine enamelled wire on the iron core of manufacturing at silicon steel to be made, and the coil of such ribbon core, when moment, ON/OFF powered on, will self-induction produce high pressure, be added on the electrode (filament) at the two ends of fluorescent tube.This action hockets, and when starter (jump bubble) is closed, the filament of fluorescent tube is by ballast current limliting conducting heating; When starter is opened a way, ballast will self-induction produces high pressure and is added on the two ends filament of fluorescent tube, and the phosphor powder of filament emission electronics bombardment tube wall is luminous, and starter is break-make several times repeatedly, will be repeatedly such action several times, thereby get through fluorescent tube.Although existing ballast has possessed some advantages, it still exists the some shortcomings part, the ballast that two kinds of main Types are arranged extensively adopted at present, the first is traditional inductance type ballast, and the power loss of this ballast self is large, and noise is large, cost is high, and weight is large.The electric ballast that the second is comprised of discrete component; this ballast, in the process of manufacturing, debug more difficultly, and the device matching screening bothers; serviceability is unstable; fail safe, reliability and homogeneity of product are poor, and power is with the voltage ripple of power network respective change, and defencive function is single; single overload protection point is difficult to accurate setting; preheating can only adopt thermistor (PTC) to realize, preheating poor reliability and consumption relatively high power, and whole ballast life is shorter.
The utility model content
The purpose of this utility model is for the problems referred to above, provide a kind of reasonable in design, simple and compact for structure, can extend the incandescent lamp intelligent chip frequency converting and preheating type electric ballast in useful life.
For achieving the above object, the utility model has adopted following technical proposal: a kind of intelligent chip frequency converting and preheating type electric ballast, comprise the rectification unit be connected with power input, it is characterized in that, the described rectification unit other end is connected with chip, comprise interconnective controller and oscillator in described chip, the controller other end is connected with internal or external driven MOS unit, and the opposite side of driven MOS unit connects output.
In above-mentioned intelligent chip frequency converting and preheating type electric ballast, described driven MOS unit is connected with for preheating and permanent power adjustments unit.
In above-mentioned intelligent chip frequency converting and preheating type electric ballast, described oscillator also is connected with respectively capacitance-resistance oscillating unit and preheat curent and operating current detecting unit.
In above-mentioned intelligent chip frequency converting and preheating type electric ballast, described preheat curent and operating current detecting unit also are connected with regulon warm-up time.
Compared with prior art, the utility model has the advantage of: the omnibearing protection function is carried out reliably protecting to various abnormalities; Adjustable pre-thermal parameter can realize best pre-heat effect, prolonging lamp tube service life; The work of wide-voltage constant power, minimum peripheral components is realized whole low-cost; Debug easy to maintenance, high conformity.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The operation principle schematic diagram that Fig. 1 is utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of intelligent chip frequency converting and preheating type electric ballast, comprise the rectification unit 1 be connected with power input, rectification unit can convert high-voltage ac power to high-voltage DC power supply, the described rectification unit other end is connected with chip 2, chip can be controlled and be driven links, comprise interconnective controller 3 and oscillator 4 in described chip, described oscillator can be regulated whole ballast operating power, lamp current, light tube electric voltage and resonance frequency etc., the controller other end is connected with internal or external driven MOS unit 5, described driven MOS unit is connected with for preheating and permanent power adjustments unit 6, the opposite side of driven MOS unit connects output.
Described oscillator also is connected with respectively capacitance-resistance oscillating unit 7 and preheat curent and operating current detecting unit 8, and described preheat curent and operating current detecting unit also are connected with regulon 9 warm-up time.The capacitance-resistance oscillating unit is for regulating frequency of oscillation, warm-up time, regulon was for regulating ballast warm-up time, preheat curent and the operating current detecting unit operating current size during for detection of preheating and during work, the technical program can be applied in the T5 fluorescent lighting fixture, and T8 turns T5 support, electric ballast, grid lamp disc, the T8 fluorescent lighting fixture, the T5/T8 twin-tube stent, on the entities such as electricity-saving lamp.
During work, rectification unit is sent high voltage direct current into chip and drive circuit, under chip controls, in the preheating of setting, enter with upper frequency to drive and supply with filament radio-frequency preheating electric current, make the abundant preheating of filament rubescent, finish warm-up time, chip is regulated frequency of oscillation to resonance frequency downwards and is made the fluorescent tube igniting, after having lighted a fire, with operating frequency, enters steady-working state.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
