Description

A kind of electroluminescent energy-saving circuit that is used for fluorescent tube
Technical field:
The utility model relates to a kind of start-up circuit that is used for fluorescent tube, relates in particular to a kind of electroluminescent energy-saving circuit that is used for fluorescent tube.
Background technology:
In the existing technology, fluorescent lamp is the illuminating lamp tube of a kind of electricity consumption as its energy, and it has high conversion rate than incandescent lamp, and is photochromic also near daylight, has been subjected to people's welcome for this reason, is widely used in the routine work life.But, old-fashioned fluorescent lamp tool adopts reactance type ballast mostly, this kind ballast has bigger induction reactance, make reactive power bigger, the overall power factor of its light fixture is 0.4-0.5, the fluorescent lamp of a 40W adds the oneself power consumption (being about 6-11W) of reactance type ballast, and actual power consumption is about 55W.Heating easily, so energy-saving effect is poor.On the other hand, the frequent starting of starter not only causes self easy damage, and is also very unfavorable to filament, has a large amount of reports to point out, the every startup of fluorescent lamp of adopting reactance type ballast once, lamp tube service life reduces 3-4 hour.After tube filament blew, fluorescent-lamp tube just can't continue to use.This kind fluorescent lamp also has that volume heaviness, electromagnetic interference, noise are big, the more high shortcoming of failure rate.
Current, the energy-saving fluorescent lamp of multiple electronic type has appearred on the market, improves to some extent than the fluorescent lamp that adopts reactance type ballast, energy-saving effect has also had significantly and has improved, with respect to the circuit of the reactance type ballast 20%-30% that can economize on electricity.But, adopting the fluorescent lamp tool of electronic ballast, surge current was bigger to the impact of circuit elements device moment when it was opened; and owing to after the fluorescent tube decreased performance, may can't normally start, and lack indispensable abnormity protection function because of starting resistor is on the low side; therefore, failure rate is very high.The energy-conservation day type light modulation of general electronic type exists also that its circuit and manufacture craft thereof are complicated, cost is higher, useful life is relative not high yet and can't make it shortcoming such as luminous to the fluorescent tube of the disintegration of filament again.
Also have a kind of capacitive ballast, adopted current-limiting resistance in its circuit, when current-limiting resistance is bigger than normal, frequently glimmer during lamp luminescence, very easily be damaged; When current-limiting resistance is less than normal, will influence the operate as normal and the light fixture working life of peripheral element again because of the heat of resistance heating generation.
The utility model content:
The purpose of this utility model is to propose a kind of electroluminescent energy-saving circuit that is used for fluorescent tube at the deficiencies in the prior art, and it cooperates with existing commercially available fluorescent tube, can normally use.
Electroluminescent energy-saving circuit of the present utility model is made of following circuit unit:
Rectification/filter unit: its input inserts civil power, and output is connected to high frequency oscillation unit, the effect of this unit be to dock into civil power carry out rectification and filtering, and export the high direct voltage that obtains after rectification and the filtering to high frequency oscillation unit;
High frequency oscillation unit: its input inserts high direct voltage, and output is connected to boosting unit, and the effect of this unit is to produce the high direct voltage of utilizing rectification/filter unit to provide the self-excitation high-frequency oscillation voltage, and export boosting unit to;
Boosting unit: its input inserts high-frequency oscillation voltage, output is connected to fluorescent tube, the effect of this unit is the high-frequency oscillation voltage of high frequency oscillation unit output is promoted, and the high frequency voltage output behind the booster tension is connected to fluorescent tube, and it is luminous that it is lighted.
Input at rectification/filter unit is connected to the protection component that suppresses surge current, and surge current is had certain inhibitory action.At boosting unit the output of fluorescent tube is connected to thermally sensitive protection component, can changes parameter, limited abnormal current to a certain extent with the effect of its electric current of flowing through.The access of protection component makes the functional reliability of circuit improve.
The high frequency voltage of its boosting unit output selectable with the two-tube pin of each pipe end of fluorescent tube in any pin output join.
Circuit of the present utility model with after fluorescent tube is connected, is inserted civil power again, just constituted complete electric circuit loop.When inserting the initial of civil power, it is that the fluorescent lamp pipe is not when constituting the load of high frequency voltage that fluorescent tube is not lighted, the high frequency voltage of boosting unit output is higher, two ends at fluorescent tube form the high-frequency and high-voltage electric field, are enough to the gas in the ionization fluorescent tube, and it is luminous that it is lighted, in case fluorescent tube light luminous after, the load that it just becomes high frequency voltage obviously reduces the high frequency voltage of boosting unit output, but still can keep the luminous of fluorescent tube.As long as the energy that civil power provides can be kept the higher-order of oscillation of this circuit, the high frequency voltage of this circuit output just can keep the luminous of fluorescent tube.
The protective measure that input of this circuit and output are taked can improve the functional reliability of the utility model circuit.In addition, adopt the utility model circuit that fluorescent tube is lighted when luminous, need not to light its filament, therefore, the temperature rise of fluorescent tube is less, can improve the working life of fluorescent tube greatly, and then the fracture of wire fluorescent tube that can't use on other daylight light fixtures also can continue luminous.
