Description

Tube standard of fluorescent lamp with Energy-saving, Life-prolonging and quick glow starter

The utility model relates to a kind of pipe support that is used for the energy-saving, service life prolonged fast starting of fluorescent lamp.

Existing fluorescent lamp, majority is lighted by neon bulb starter and Inductive ballast, during startup, neon bulb starter often needs to beat and fluorescent lamp could be lighted for several times, more is difficult to start when voltage is low, and this certainly will cause the overheated of filament, even the easy disintegration of filament, and this neon bulb starter produces stronger spark interference, the easy scaling loss bonding in its contact, life-span weak point when starting.Traditional daylight lamp circuit is when operate as normal, and its operating current can only be from the end circulation of each filament, and filament effective resistance and heating loss are big so on the one hand, the filament heating is inhomogeneous on the other hand, cause local temperature rise too high, incandescent spot occurs, the easy scaling loss in joint.So the red-hot high temperature of filament localized sustained all can make electron emission substrate (triplex carbonate) volatilization loss on filament surface big when causing the overheated and operate as normal of filament in start-up course, fluorescent tube blackout easily is aging, directly influences the life-span of fluorescent tube.

Chinese patent CN85204213 number a kind of " fast starter for prolonging service life of fluorescent lamp and saving energy " disclosed, the various existing problems of existing neon bulb starter have been solved preferably, but owing to adopted no-voltage triggering and conducting silicon controlled mode, the time on turn-on lamp silk thread road is very short in each cycle scope of voltage like this, the time of preheating filament is inevitable longer, even may cause filament pre-heating insufficient and influence the startup of fluorescent lamp, and circuit is complicated, element is more, cost is higher, is preventing the inhomogeneous easy scaling loss in joint that makes of filament heating, fluorescent tube easily blackout aspect does not have big change.

The purpose of this utility model is to design a kind of energy-saving, service life prolonged fluorescent lamp pipe support simple in structure, replace traditional neon bulb starter, can accelerate the toggle speed of fluorescent lamp, can avoid filament overheated again, reduce the loss of filament wattage under the operating state and the volatilization loss of filament surface electronic emitting substance effectively, save electric energy, life-saving.

The purpose of this utility model realizes as follows: the utility model is on the basis of traditional fluorescent tube, Inductive ballast, lamp tube socket and housing of maintenance, adopted the crest voltage of forming by one-way SCR and resistance to open the two ends that brightness device And is associated in fluorescent tube, replace traditional neon bulb starter, guaranteed fluorescent tube the startup stage abundant preheating and start fast.Also be connected with the balanced bridge of the heater current of forming by semiconductor diode at the two ends of every filament, overcome that the filament heating is inhomogeneous, local temperature rise is high, the easy shortcoming of blackout of joint easy scaling loss, fluorescent tube, also be provided with combustion-supporting in addition, further quickened the toggle speed of fluorescent lamp.

The utility model is simple in structure, and is with low cost, and fast, the contactless spark of starting speed disturbs, and compares with traditional fluorescent tube circuit, can reduce about 75% of filament power consumption, and extended day light modulation tube lifetime is more than at least three times, and power savings is good.Tube filament is difficult for overheated, and the lamp tube joint place is difficult for scaling loss, and it is aging that fluorescent tube is difficult for blackout, still can guarantee quick startup in voltage, occasion that temperature is lower.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing:

Fig. 1 is a shape assumption diagram of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

With reference to Fig. 1～2, wherein S is a fluorescent tube, and J is a lamp tube socket, and P is a housing, and L is an Inductive ballast, and H is combustion-supporting electrode, and E is by crest voltage starter and the balanced bridge assembling of heater current all-in-one-piece energy-saving unit for prolongating service life.

The crest voltage starter is supply voltage peak value or conducting during near peak value, a kind of noncontacting switch that turn-offs after the supply voltage zero passage, by one-way SCR T and resistance R 1, R2 forms, the balanced bridge of heater current is made up of semiconductor diode D1～D4, after connecing, D2 negative pole and D3 Zheng Ji And meet an end M of AC power, D2 positive pole and D3 negative pole connect 3 of filament respectively, 4 two ends, D1 is anodal to be connect after Inductive ballast L meets the other end N of AC power with D4 Fu Ji And, D1 negative pole and D4 positive pole connect 1 of filament respectively, 2 two ends, resistance R 1, R2 series connection connects 2 of filament respectively again with behind the anode A of one-way SCR T and the negative electrode K And connection, 3 two ends, the control utmost point G of T is connected between R1 and the R2.

After AC power was connected, if when transient voltage is positive half cycle, AC power was by 1,2 two ends of N end by Inductive ballast L, D1, filament, through 3,4 ends of R1, R2, filament, the D2 other end M to AC power.When positive half cycle voltage rises to peak value or during near peak value, by resistance R 1, the dividing potential drop effect of R2, when the voltage that is assigned at the R2 two ends is enough to trigger one-way SCR T, T is conducting immediately, make the filament energising preheating of fluorescent tube two ends, a period of time behind positive half cycle voltage zero-cross, under the effect of power-half cycle voltage, force T to turn-off, so repeatedly, provide periodically wide pulsed preheat curent to filament, in case filament pre-heating is to ignition temperature, subsequently in shutoff moment of T, fluorescent tube ignites immediately, after igniting, lamp tube ends voltage descends, and promptly voltage descends between the anode of T and the negative electrode, this moment is by resistance R 1, the control pole tension that the R2 dividing potential drop is added on T can not trigger the T conducting again, and T is in off state always.

Resistance R 1, R2 resistance are selected according to different model one-way SCR T, the resistance difference, and the angle of flow of T is also different, generally is adjusted at peak value or triggers near peak value, to guarantee that lighting back T is in off state.

The balanced bridge of the heater current that D1～D4 forms, after fluorescent tube is ignited, the positive-negative half-cycle of its operating current is respectively in the alternately circulation of the two ends of every filament, on heating effect, the effective value of 1～4 end of its filament is balanced equivalence, therefore reduce filament effective resistance and the heating loss under the normal operating conditions, overcome the drawback that filament heating filament surface electronic emitting substance volatilization loss inhomogeneous and that the red-hot high temperature of localized sustained causes is big, fluorescent tube easily turns black.

The present invention also is equipped with combustion-supporting, forms by capacitor C and combustion-supporting electrode H, and the combustion-supporting electrode H of capacitor C one termination, any end of the balanced bridge of another termination AC power or crest voltage starter and heater current preferably connects the live wire end of AC power.H is the one section electric conductor that axially is provided with along fluorescent tube, can be arranged in outside the fluorescent tube, near fluorescent tube, also can utilize the combustion-supporting electrode H of housing P double as far as possible.The effect of combustion-supporting is to arrive ignition temperature when filament pre-heating, constantly subsequently in the shutoff of one-way SCR, high frequency composition in the line voltage distribution (comprising the induced electromotive force that Inductive ballast L produces) is added on the combustion-supporting electrode H by capacitor C, produce high-frequency electric field, under the acting in conjunction, further guarantee igniting immediately of fluorescent tube, make the warm-up time error be no more than 20 milliseconds, therefore avoided the mistake cause thermal damage of filament.For the fluorescent tube below the 20W, can be without combustion-supporting.
