Description

Pulsed gas-filled lamp

The present invention relates to electric light source technology.As everyone knows, gas-filled lamp is can independently operate after a kind of energized and produce the electric light source of visible light or invisible light, it comprises that feeder equipment (has and starts or triggering, the electric device of function such as the current limliting or the change of current or electronic installation), electric lighting device is promptly inflated fluorescent tube/bulb, annex (base, lampshade etc.), circuit diagram can be represented its major technology feature, and the circuit that is adopted depends on operation scheme, the electro-optical characteristic of inflation fluorescent tube/bulb, kind of power supply (AC/DC) and specification (high/low voltage), whether lay particular emphasis on some index such as reliability, economy, volume etc.

Improvement and innovation to gas-filled lamp, carried out a large amount of research both at home and abroad, have energy-saving fluorescent lamp, electrodeless fluorescent lamp that the comparatively ripe person of characteristics and technology has electric ballast formula fluorescent lamp, adopts highly effective fluorescent tube, the former two's electric light transfer ratio is that luminous efficiency also is that light efficiency increases, latter's life-span is extremely long, easy to use, as if the light efficiency peak of existing gas-filled lamp is about 100 lumens/watt, difficult again the raising.

The objective of the invention is, provide and adopt the high gas-filled lamp of brand-new operation scheme, light efficiency and supporting with it lock streaming/coaxial type/the have various inflation fluorescent tube/bulbs and the incorporate pulsed gas-filled lamp bubble of thermal insulation layer.

Accompanying drawing 1 is an operation scheme schematic diagram of the present invention, accompanying drawing 2 is circuit diagrams of lock streaming inflation fluorescent tube/bulb, and accompanying drawing 3 is circuit diagrams of 5 kinds of circuit arrangements, and accompanying drawing 4/5/6/7/8 is 5 kinds of practical circuits, hereinafter will be in conjunction with the accompanying drawings, describe technical scheme of the present invention in detail.

Accompanying drawing 1 is that operation scheme schematic diagram of the present invention is lamp power-time spy The property figure, the longitudinal axis for the inflation fluorescent tube lamp power P G, transverse axis is time t, feed Install periodically feed and give the inflation fluorescent tube and have following characteristics, be i.e. each week Lamp power waveform in the portion of time Tc of phase T is that rectangular pulse, numerical value are Pmax, the lamp power in another part time T o be zero or very little be Pmin, Cycle T=Tc+To makes Tc much smaller than To, and then lamp power virtual value is far away Less than flashlight power, namely flashlight power is much larger than lamp power virtual value, and Produce the optical parameters such as corresponding pulsed light flux, because human eyes are to this The sensation of high light postpones if having time, so light efficiency is improved unusually, shows Right Tc is littler, more then light efficiency is higher for To and T, and the shortening of Tc is filled The restriction of the factors such as the electrical characteristics of gas lamp pipe and circuit, the prolongation in its cycle are frequently namely The reduction of rate is subjected to people's vision spy in general applications is the electric light source of pure illumination The property restriction---film per second kind flash of light 48 times (show 24 frames each second, every Frame projection 2 times), TV glisten 50/60 time each second (field frequency 50/60Hz), Fluorescent lamp glistens each second, and 100/120 time (mains frequency 50/60Hz, fluorescent tube is every Week conducting and cut-off each 2 times), the equal flicker free sense of human eye under the normal condition, it is former Because being, when instantaneous photoperiodism took place intermittently, human eye was to instantaneous light once Feel that extending to next instantaneous light takes place the time, then human eye perceives only continuously and Non-intermittent be the flicker free sense, still, fluorescent lamp at line voltage very low or/ When old and feeble with the very low or/and fluorescent tube of temperature, human eye perceives light has certain degree Flicker, when above-mentioned three kinds of deadly conditions took place, fluorescent tube was per half of alternating current The conducting phase in week shortens, the off period prolongs is lamp current and lamp power and light Dutycycle reduce, repetition rate does not become (mains frequency does not become), this shows, Make human eye to periodically interrupted instantaneous smooth flicker free sense, certain lamp power Will match with quite high frequency with the dutycycle of light, its rule is duty Bigger than, lower-frequency limit is lower (such as film, TV), dutycycle is littler, frequently Rate lower limit higher (such as fluorescent lamp) is so if try hard to adopt minimum lamp among the present invention Power duty cycle also will be equipped with sufficiently high frequency when seeking high light efficiency Rate, namely the lower limit of frequency should be take human eye to its light flicker free sense as limit, light The extreme of effect improves so is restricted, and even so, fills with respect to existing It is to realize easily that gas lamp, light efficiency improve more than the several times; In addition, some is special The flash of light electric light source of purposes utilizes human eye that the flickering of light is made and induces one to annotate The objective vision effect, flash lamp, ambulance and the police car used such as the noon Room and noon platform With flash-mode warning lamp, commercial advertisement lamp, traffic mark lamp and indoor security logical The floating lamp of road mark lamp, navigation usefulness and beacon projecting lamp etc. are if adopt this Bright, its upper frequency limit take human eye to its light have flickering as limit (with above-mentioned The lower-frequency limit of lighting electric light source of general applications adjacent), practical Good frequency is decided according to the purposes of product, have or even very low frequencies; Of the present invention Operation scheme has utilized inflation fluorescent tube energy instantaneous light emission and its duration to manage Accomplish extremely short characteristic and human vision property, because electric light source is in the overwhelming majority The fine service of eye for the mankind in the situation, with the visual experience of the people in the scene Be final purpose, so the present invention's application is very wide, meaning is quite big, certainly also do not arrange Except relating to the purposes of other animals, as lure worm, kill mosquito ultraviolet lamp.

Above-mentioned electrodeless fluorescent lamp, claim the induction type fluorescent lamp again, comprise higher-order of oscillation power supply and load-sensing coil thereof, fluorescent lamp bulb, annex, fluorescent lamp bulb is made by the traditional fluorescent lamp tube manufacturing technology, as at glass cell-shell inner surface coated fluorescent material etc., its center is provided with induction coil, the part of higher-order of oscillation power supply is assembled in the shell of garden cylindricality to high-density, an one end face electrically connects and mechanical attachment normal lamp holder such as screw cap, another end face electrically connects and mechanical attachment induction coil and fluorescent lamp bulb, become the integral lighting source that profile is similar to incandescent lamp bulb, the common lamp socket of packing into can use, load and unload very easy, the volt-ampere electrically conducting manner of its operation scheme and common gas-filled lamp is completely different---and higher-order of oscillation power feed produces the electromagnetic field of high frequency to induction coil, mercury vapour in the ionization fluorescent lamp bulb and produce ultraviolet ray, excitated fluorescent powder and send visible light again, it is ripe that this new type electro source has become technically, that has reported has E type lamp (United States Patent (USP) product) and QL lamp (Philip light company) and an altar lamp (PANASONIC) etc., because of there not being electrode in the fluorescent lamp bulb, its life-span only depends on that so the decline of fluorescent material is extremely long, it is said and to reach 2-6 ten thousand hours, light efficiency equates with the conventional fluorescent lamps of equal-wattage grade or is low slightly, can be improved in conjunction with feature of the present invention by (referring to accompanying drawing 1)---change former higher-order of oscillation power supply into periodically higher-order of oscillation power supply interrupter duty or periodic amplitude-modulated, very big and its envelope waveform of amplitude is a rectangle in the portion of time Tc of each interruption period or amplitude modulation period T, the failure of oscillations or amplitude are very little in another part time T o, the envelope waveform of high-frequency sasser is that the shared time T c of the part of rectangle is much smaller than the failure of oscillations or the very little shared time T o of part of amplitude, so just make the former flashlight power promptly improve light efficiency significantly much larger than lamp power effective value, this pulsed electrodeless fluorescent lamp has the advantage of the two concurrently, and promptly light efficiency is high, life-span is extremely long, use very easy.

Compare with above-mentioned operation scheme, fairly simple effective, easy to implement is dc pulse current operation scheme (referring to accompanying drawing 1): feeder equipment is periodically fed intermittently and is inflated the fluorescent tube dc pulse current and have following characteristics, lamp current waveform in the portion of time Tc of each interruption period T is a rectangular pulse, stopping feed in another part time T o is that fluorescent tube ends, the conducting phase Tc of fluorescent tube is much smaller than off period To, so just make the flashlight electric current very big with the ratio of lamp current effective value, though because the negative resistance charactertistic of fluorescent tube, the ratio of flashlight power and lamp power effective value is less than the ratio of flashlight electric current with the lamp current effective value, but still greater than in addition much larger than existing gas-filled lamp, promptly light efficiency is improved significantly.

It is that energy-storage capacitor is to having the gas-filled lamp tube discharge of negative resistance charactertistic that a storage has the capacitor of quite high voltage, promptly produce peak value is very big, the duration is very short dc pulse current, flashlight power, pulsed light flux, the electronic camera photoflash lamp promptly so; Most of inflation fluorescent tube/bulb is in very big current range, and tube voltage drop reduced when its voltage-current characteristic showed as the electric current increase, tube voltage drop increased when electric current reduced, i.e. negative resistance charactertistic; As everyone knows, by DC power supply, resistor, capacitor, two ends or three end negative resistance devices can be formed relaxation oscillator, be commonly used for the trigger of thyristor SCR, if be used for the present invention, because the resistor loss is bigger, then replace resistor with low-frequency choke coil or transistor converter and and energy-storage capacitor, inflation fluorescent tube with negative resistance voltage-current characteristic is formed relaxation oscillator, fluorescent tube is the negative resistance device with breakdown voltage value of one of three elements of formation relaxation oscillator, again the electro-optical conversioning device electric lighting device during conducting, and the conducting phase is much smaller than its off period, dc pulse current numerical value is very big, become a kind of simple of above-mentioned dc pulse current operation scheme and effective embodiment, should be understood that, energy-storage capacitor should adopt the capacitor of distribution-free inductance, tend to sinusoidal wave otherwise the waveform of lamp current will depart from square wave, in addition, the inflation fluorescent tube also must configuration flip-flops be triggered.Suppose in above-mentioned relaxation oscillator, to adopt existing inflation fluorescent tube, because the lamp current effective value is much smaller than rated value, for the low-pressure mercury fluorescent tube, can not produce thermoelectricity and give emission so can not adopt, for xenon lamp pipe etc., to make the thermionic emission wretched insufficiency, cause electro-optical characteristic and dynamic range extremely unstable, be difficult to practicality, in addition, because existing inflation fluorescent tube is the very big gas diode of electrode spacing, so be difficult to start and regulation and control, according to above-mentioned analysis and relevant experimental result, show that existing inflation fluorescent tube can not be used for dc pulse current operation scheme and relaxation oscillator circuit, must be improved; Improved way is to draw the characteristics of thyratron, is lock streaming inflation fluorescent tube from former gas diode architecture advances for the gas-filled triode structure, its architectural feature is, an end in space in the fluorescent tube, from end top order heated filament and equipotential cathode assembly are set, grid is promptly controlled the utmost point and is used respectively outside the lead extraction tube, the outer surface of the grid lead wire in the pipe should insulate properly to prevent to contact the grid characteristic that gas promptly guarantees its setting, the other end in space is provided with anode also with outside the lead extraction tube in the fluorescent tube, accompanying drawing 2a is the circuit diagram of lock streaming inflation fluorescent tube, A is an anode, G is that grid is promptly controlled the utmost point, K is a negative electrode, H is a heated filament, round dot represents that gas-filled tube is to be different from vacuum tube, energising heated filament and electric heating negative electrode promptly produce sufficient and stable thermionic emission, the grid positive pulse of feeding voltage (with respect to negative electrode) and trigger the peak pressure value that fluorescent tube makes it conducting will be than little 1～3 order of magnitude of existing inflation fluorescent tube, grid current is very little in addition, so it is very little to trigger power, the two is as far apart as heaven and earth, sufficient and the stable thermionic emission and the sensitivity of grid and reliably control performance make its dynamic range very big and can arbitrarily set, the stability of the operating state of fluorescent tube and relaxation oscillator greatly improves, even the very high flashlight current waveform trend of the current-rising-rate after fluorescent tube conducting rectangle, the conducting phase is compressible to the utmost point short, there is not resistance (for fluorescent tube) in current circuit so can move to the saturation region and have the requirement that pure negative resistance charactertistic promptly satisfies relaxation oscillator fully in the fluorescent tube, has prepared impeccable condition for farthest improving light efficiency; Among the accompanying drawing 2a, for making anode breakdown voltage enough low, anode and gate pitch should be enough little, then can much bigger (being that saturated tube voltage drop and lamp power can be much bigger) among the accompanying drawing 2b, setting up one in the fluorescent tube arranges by anode A-grid G direction, resistive layer exposes can contact with gas in the pipe, the end-to-end distance anode A is quite near and the latter two resistance R that electrically connect apart from grid G is quite near for head end, during triggering, first conducting between grid and negative electrode, puncture subsequently between the head end of resistance R and grid and the breakdown region postpone to the resistance end until anode, finish rapidly like this process blast, so anode breakdown voltage is still quite low, so without the electrode of non-resistance value, is for fear of the axial ionized gas of short circuit with resistance R; If normal temperature solids such as built-in certain halide of fluorescent tube or sulphur also makes it gasification with electric heating when requiring work, appropriate location that then can be in fluorescent tube be provided with the heated filament that is no less than 1 group and with lead with outside its two ends extraction tube or with extraction tube after the heated filament in the equipotential cathode assembly is in parallel outside, accompanying drawing 2c/d divides in addition corresponding to accompanying drawing 2a/b, one group of heated filament H1 is as electric heating negative electrode K, and another group heated filament H2 is as normal temperature solids such as electric heating sulphur; The visual series of products of making the lock streaming inflation fluorescent tube shown in the accompanying drawing 2a of three kinds of lock streaming inflation fluorescent tubes shown in the accompanying drawing 2b/c/d, all identical to the requirement of circuit, they will be that representative appears in each circuit diagram that hereinafter relates to the circuit diagram of accompanying drawing 2a.

Above-mentioned lock streaming inflation fluorescent tube is if adopt coaxial configuration, to have some advantage, its architectural feature is, the straight shape glass outer tube that its body is increased gradually by a straight shape glass inner tube and the diameter that is no less than 1 forms (its cross section is a concentric circles) by the structure and the ascending order suit of diameter at same axis center, the mouth of pipe of inner and outer pipes all seals space outerpace, space has following characteristics in it, one end of interior pipe is made as left end, from end top order heated filament and equipotential cathode assembly are set, grid is also used respectively outside the lead extraction tube, the outer surface of the grid lead wire in the pipe insulate properly, the mouth of pipe that the other end of interior pipe is made as right-hand member communicates with the right-hand member mouth of pipe of the 1st outer tube, the 1st, the left end mouth of pipe of 2 outer tubes communicates, the 2nd, the right-hand member mouth of pipe of 3 outer tubes communicates ... one end of the remainder of last root outer tube is provided with anode and uses outside the lead extraction tube, for the current density that makes inner and outer pipes equates that the cross-sectional area of interior pipe equates with the cross section net area of each outer tube; The direct result of this coaxial type lock streaming inflation fluorescent tube is into several times ground and shortens pipe range, if its draw ratio narrows down to a certain degree, promptly become tubular lamp bulb, its ion flow length will greater than in addition much larger than existing gas-filled lamp bulb such as high-pressure mercury bulb, its saturation voltage drop and lamp power also correspondingly increase, if xenonlamp, because of its power density big, the great point-source of light of luminous flux be will become, flood light, pulse laser etc. can be used for.

Lamp power effective value among the present invention is much smaller than its pulse value, so the heat power consumption and the body temperature rise of inflation fluorescent tube are also quite little, this is for the xenon lamp pipe, its life-span will prolong to some extent, do not need artificial cooling, but for the mercury lamp pipe, then can reduce light efficiency in certain degree ground, must set up a thermal insulation layer, promptly outside inflation fluorescent tube or inflation tubulose bulb, press the bigger straight shape glass outer tube or the outer glass cell-shell that the bodily form is bigger of diameter of structure suit at same axis center, its two ends mouth of pipe or cell-shell end all are melt into one to the sealing of inflation fluorescent tube/bulb and space outerpace and with the respective end of inflation fluorescent tube/bulb and stay to bleed and chew, space is evacuated in it, this scheme can be used for ultraviolet mercury lamp pipe/bulb etc., if straight shape glass outer tube or outside the inner surface coated fluorescent material of glass cell-shell, fluorescent tube/bulb; The setting of thermal insulation layer can be reduced or remitted the negative influence to light efficiency of the heat dissipation of inflation fluorescent tube/bulb, the temperature rise that improves the inflation body and external factor such as light efficiency, deduction and exemption temperature and air-flow, create conditions for being applied to the open air, and fundamentally eliminate a class disadvantage of traditional fluorescent lamp tube incidental lamp tube ends uneven luminance when low temperature and dc pulse current operation.

Among the accompanying drawing 3a, meet energy-storage capacitor C and lock streaming inflation fluorescent tube TG behind the DC power supply DC series connection low-frequency choke coil LFC, its connection should make the latter (TG) obtain anode A for just, negative electrode K is negative voltage, vibration trigger T and negative grid voltage power supply-UG are set, output circuit (generally being coil) and the latter of the former (T) (UG) connects respectively or the two connects grid G and the negative electrode K (being tandem-type connection among the figure) of fluorescent tube TG after connect again, its connection should make the negative pole of the positive pole of pulse voltage of vibration trigger I output and negative grid voltage power supply-UG be connected to or extend to the grid G of fluorescent tube TG, and the heated filament H of fluorescent tube TG is generally powered by low-voltage AC/DC power supply; After the energising, DC charges (between charge period through LFC to C, provide negative grid voltage by-UG and TG is ended), through setting-up time (being the off period To of TG), the voltage of C reaches set point, the T voltage pulse output is offset negative grid voltage and is triggered TG and make it conducting (establishing its thermionic emission has reached normally), C promptly discharges until end to TG, because the conducting phase of TG is the charge period of C much smaller than its off period, so the recharge current of C and voltage have little time to increase, end so TG transfers to, then C recharges, T triggers TG again, TG is conducting again, C discharges again, TG ends again ... go round and begin again, form the Zhang Zhen that speeds and swing; This circuit can be described as L.C.T.T circuit/relaxation oscillator (LFC.C.TG.T), is one of typical circuit scheme of dc pulse current operation scheme of the present invention.Among the accompanying drawing 3b, DC power supply DC is the single-ended blocking oscillator B0 power supply of unsymmetrical oscillation waveform to converter, among the latter's (B0) the ferritic transducing transformer of the use T pulse voltage output winding being set is charge coil L3, connect the anode A of energy-storage capacitor C and lock streaming inflation fluorescent tube TG behind the positive pole of its pulse voltage positive terminal (round dot mark) order series diode D, the negative pole, the other end of another termination energy-storage capacitor C and the negative electrode K of fluorescent tube TG, vibration trigger T and negative grid voltage power supply-UG preamble are stated, are omitted; After the energising, B0 produces intermittent oscillation, between its off period, L3 produces pulse voltage, charge to C through the D rectification, through several all after dates, the voltage of C reaches set point, the T voltage pulse output is offset negative grid voltage and is triggered TG and make it conducting (establishing its thermionic emission has reached normally), C promptly discharges to TG, TG transfers to and ending during end, then C recharges, T triggers TG again, TG is conducting again, C discharges again, TG ends again ... go round and begin again, the Zhang Zhen that speeds swings in formation, the charging interval that the B0 that sets transform power charges to setting voltage value with C is that the charge period of C also is the off period To of TG, and To is the conducting phase TC of TG much larger than C to discharge time of TG, because C carries out between the off period at B0 the discharge of TG, so the intermittent oscillation of B0 is not had direct influence, this also is can not adopt the push-pull type oscillator of symmetric oscillations waveform and the reason that must adopt the single-ended blocking oscillator; This circuit can be described as B.C.T.T circuit/relaxation oscillator (B0.C.TG.T), is one of typical circuit scheme of dc pulse current operation scheme of the present invention.Accompanying drawing 3C is the special case of accompanying drawing 3b, DC power supply DC is low-voltage (as 12V) and the heated filament H that meets lock streaming inflation fluorescent tube TG, setting up a pulse voltage output winding among the ferritic transducing transformer of the use of the blocking oscillator B0 T is trigger winding L4, connect the grid G of fluorescent tube TG after its pulse voltage positive terminal (round dot mark) string resistor R, the negative pole of another termination DC power supply DC, the negative electrode K of fluorescent tube TG connects the positive pole of DC power supply DC, charging circuit preambles such as charge coil L3 have been stated, are omitted; Between the off period of B0, the pulse voltage of L3 is charged to C through the D rectification, through several all after dates, the voltage of C raises gradually, in certain B0 off period, the voltage of C is increased to set point, the pulse voltage of L4 also reaches set point, and (waveform as shown in the figure, To is the off period of TG), offset negative grid voltage and trigger TG and make it conducting (the R restriction triggers grid current, TG ends because of DC provides negative grid voltage before this), C is promptly to the TG discharge, and discharge finishes back TG and ends, and then repeats said process again and again, the formation Zhang Zhen that speeds swings, and electric circuit characteristic is that the heated filament of fluorescent tube and negative grid voltage are by DC power supply, the vibration trigger of transducing transformer double as fluorescent tube and farthest simplify circuit.If lock streaming inflation fluorescent tube is bigger by negative grid voltage, then the negative grid voltage power supply must be set separately, among the accompanying drawing 3d, it is negative grid voltage coil L5 that above-mentioned transducing transformer T sets up a pulse voltage output winding again, its pulse voltage positive terminal (round dot mark) meets the negative electrode K of lock streaming inflation fluorescent tube TG, the negative pole of other end order series diode D2, anodal, meet the negative electrode K of fluorescent tube TG after the resistor R 2, the positive pole of diode D2 and the series connection point of resistor R 2 contact the negative electrode K that meets fluorescent tube TG behind the pulse voltage negative pole end of hair line circle L4/the connect capacitor C2 respectively, other circuit are same as accompanying drawing 3C, are omitted; The pulse voltage of L5 becomes the negative grid voltage of TG after D2 rectification, C2 filtering, R2 and C2 provide and trigger the grid current path.If the DC power supply battery in the accompanying drawing 3b/c/d circuit, then its voltage is comparatively stable, the transform power of single-ended blocking oscillator B0 constant substantially (it is constant to establish loading condition), if DC power supply be high-tension direct current network or by the voltage of AC network through rectification, filtering and getting, its magnitude of voltage may fluctuate bigger, B0 must adopt degenerative sampling, error amplifier is regulated and control, optimize the circuit of accompanying drawing 3d for this reason and obtain the circuit of accompanying drawing 3e, among the ferritic transducing transformer of the above-mentioned use T 3 pulse voltage output windings being set is charge coil L3, trigger winding L4, negative grid voltage coil L5, the pulse voltage negative pole end ground connection (GND) of charge coil L3, the positive pole of other end order series diode D1, meet anode A and the energy-storage capacitor C1 of lock streaming inflation fluorescent tube TG behind the negative pole, the latter's (C1) the other end connects positive pole/resistor R 2 of the negative electrode K/ electrolytic capacitor C4 of fluorescent tube TG respectively, back (C4, R3) the equal ground connection of the other end, the pulse voltage positive terminal of negative grid voltage coil L5 (round dot mark) ground connection, the negative pole of other end order series diode D2, anodal, resistor R 2, ground connection behind the capacitor C3, the series connection point of the positive pole of diode D2 and resistor R 2 connects ground connection behind the capacitor C2, resistor R 2 and the series connection point of capacitor C3 connect anodal and its minus earth of voltage stabilizing didoe D3/contact the pulse voltage negative pole end of hair line circle L4 respectively, connect the grid G of fluorescent tube TG behind the latter's (L4) the other end string resistor R1; The pulse voltage of L5 is through the D2 rectification, after the C2 filtering, again by R2, supply with the TG negative grid voltage after the D3 voltage stabilizing, make L4 stablize constant (grid characteristic of establishing TG is constant) to the triggering and conducting voltage peak of the grid of TG, TG is triggered and C1 reaches during conducting magnitude of voltage is also stablized constant, thereby make the conducting phase TC of TG, the flashlight electric current, flashlight power, the pulsed light flux is all stablized constant, if the off period To of TG is the charge period of C1, charging current effective value and the voltage drop on R3 thereof (C4 filtering ripple) are stablized constant, cycle then, frequency, lamp power effective value is that the transform power of B0 is also stablized constant, if change is arranged, the voltage drop of R3 changes thereupon, so with the voltage drop of R3 sampling voltage as the negative feedback error amplifier NFA among the B0, carrying out negative feedback regulates automatically, just can make B0 keep the constant output characteristic of output, avoid mains fluctuations and make the electro-optical properties change, the variation of temperature and fluorescent tube characteristic is also had the compensation of certain degree; After after turning on light, promptly switching on, to just produce thermionic emission through the negative electrode of TG after considerable time and tend to normal gradually, therebetween, still can not can not discharge because of TG in C1 charging back in conducting, charging current trend zero, the R3 voltage drop also tends to zero, NFA is with out of control, if same situation also can take place in components and parts such as TG when damaging, consequently, B0 underloading and operation out of control, the pulse voltage of each coil of T all outclasses set point, can cause oscillating tube among the B0 ill effect such as to smash, thus among the figure with the pulse voltage of negative grid voltage coil L5 through the D2 rectification, C2 filtering and the direct voltage that obtains as the sampling voltage of negative feedback error amplifier NFA (from other coils of T or set up a coil sampling also can), make B0 in the warm-up time of TG or during deadly condition such as TG damage, press the state operation of switching regulator stabilized voltage power supply.

The switching regulator stabilized voltage power supply of color TV set has many kinds of circuit, all adopt the single-ended blocking oscillator of band transducing transformer, its main difference is the design difference of oscillating tube base circuit, length is respectively arranged, difficult branch uncle stretches, vibration trigger T in 5 kinds of circuit arrangements of accompanying drawing 3 and single-ended blocking oscillator B0 also can have many kind designs, be difficult to exhaustive, B0 can revise slightly with some the switching regulator voltage-stabilized power supply circuit of color TV set even thick film integrated circuit and form, former the pulse voltage output circuit with the transducing transformer of B0 provides, in the practical circuit hereinafter, T and B0 respectively have a routine circuit.

Accompanying drawing 4 is the circuit arrangement of 3a with reference to the accompanying drawings and the practical circuit that designs: connect the main coil of input/heater transformer HT of bridge rectifier D 1-D4 and the heated filament H that its pair coil meets lock streaming inflation fluorescent tube TG behind 2 AC power (AC) inlet wire series lamp switch S and the fuse F respectively, connect the two ends of filtering behind the output series connection limit peak flow resistor R1 of bridge rectifier (D1-D4) with electrolytic capacitor C1, the positive pole of capacitor (C1) is termination resistor R2/ low-frequency choke coil LFC respectively, the latter's (LFC) the other end meets anode A/energy-storage capacitor C3 of fluorescent tube TG respectively, negative electrode K and the ground connection (GND) of another termination fluorescent tube TG of capacitor (C3), the other end of resistor R 2 is the main coil L1 of termination resistor R3/R6/ capacitor C6/ pulse transformer T respectively, anode and its minus earth of another termination thyristor SCR of the latter (L1), its control utmost point and negative electrode indirect resistance device R5, the other end ground connection of capacitor C6, the negative pole of the other end order series diode D13 of resistor R 6, anodal, resistor R 7, ground connection behind the capacitor C8, the series connection point of the positive pole of diode D13 and resistor R 7 connects ground connection behind the capacitor C7, the series connection point of resistor R 7 and capacitor C8 connects anodal and its minus earth that coil L2/ meets voltage stabilizing didoe D14 of paying of pulse transformer T respectively, the other end of paying coil L2 of pulse transformer T is the grid G that meets fluorescent tube TG behind the pulse voltage positive terminal resistors in series R8, the positive pole of the other end order series diode D9 of resistor R 3, the negative pole of negative pole and voltage stabilizing didoe D10, meet negative pole/bidirectional trigger diode D12 of capacitor C4/ voltage stabilizing didoe D11 behind the positive pole respectively, the control utmost point of another termination thyristor SCR of the latter (D12), the negative pole of another termination electrolytic capacitor C1 of capacitor C4, the positive pole of voltage stabilizing didoe D11 connects the collector electrode of NPN type triode Q, its base stage string is protected with ground connection behind the resistor R4, its emitter connects the negative pole of electrolytic capacitor C1, between the negative pole of ground connection (GND) and electrolytic capacitor C1, the forward diode D15 and the D16/ backward diode D17 of two series connection of difference shunt capacitor C5/; After connecting AC power, obtain direct voltage U2, through LFC C3 is charged, through R2 C6 is charged simultaneously, D10 punctured after C6 voltage rose to certain numerical value, through R3, D9, D10 charges to C4, the former two's charging current is at D15, voltage drop on the D16 makes Q conducting and saturated, the voltage of C4 is clamped at the breakdown voltage value of D11, the latter is lower slightly than the breakdown voltage value of bidirectional trigger diode D12, C3, after the charging of C6 all finishes, Q ends, the voltage of C4 rises to rapidly and punctures D12, trigger SCR (R5 shunts the leakage current of the two), pass through SCR, C6 discharges to L1, and the resonance current that peak value is the very big L1 that flows through, L2 voltage pulse output offset negative grid voltage and trigger TG (R8 limits grid current) and make it conducting, C3 promptly discharges to TG, end back TG transfers to and ending, and behind C6 and the L1 resonance half cycle, C6 is reversed charging, SCR is subjected to reverse voltage and ends, the negative pressure over the ground of C6 is through D13 rectification (R6 current limliting), after the C7 filtering again through R7, D14 voltage stabilizing and supply with the stable negative grid voltage UG of TG, D14, C8 provides path, C5 for triggering grid current, D17 improves transient response, after this circuit repeats said process again and again, forms the Zhang Zhen that speeds and swings; The charge period that generally is set at LFC and C3 is greater than the charge period of R2 and C6 and be the off period of TG (C4 is seldom time-consuming from the breakdown voltage value that the breakdown voltage value of D11 rises to D12), because of the charging of C3 being had resonance characteristic through LFC, the less influence that is subjected to external cause is so the stability of the off period of TG and speed a period of oscillation and frequency better; The equivalent inductance of L1 and C6, the relaxation oscillator of compositions such as SCR is made the vibration trigger of TG, its advantage is to export bigger pulse power (the moment overcurrent multiple of SCR is very big) in the extremely short time, this point is better than the oscillator of other types, but because of L1, the loop Q value of C6 is relatively low, if SCR conducting when the voltage of C6 hangs down, the situation that C6 does not have reverse voltage can take place, SCR conducting and not ending this moment, entire circuit is blocked and can not be moved, after turning off the light, turn on light immediately or AC power moment like this when interrupted, so insert 310, D10 is just breakdown and C4 is charged when the voltage of C6 is quite high, SCR just is triggered, and has avoided above-mentioned disadvantage.
