Below some physical circuits in the foregoing description are further specified:
One, power-supply filter
Power-supply filter has two kinds of effects; One is to prevent that the lamp power supply noise from scurrying people's power network, disturbs other power consumption equipments; Its two, can stop the defeated thin and weak man's power supply of noise in the power network, influence the operate as normal of lamp.Its circuit as shown in Figure 2.
The two-stage type power filter network that power-supply filter is made up of inductance and electric capacity, the frequency that suppress mainly are about 50kHz of the operating frequency of PFC and DC/AC switching frequency 2.65MHz, and the high order harmonic component of these two frequencies.CX1, CX2, CX3 also are X electric capacity, and the differential mode interference noise is bypassed.LF1, LF2 are common mode choke, suppress common-mode noise.CY1, CY2 also are Y electric capacity, are used to suppress the radio noise of power transmission line secondary.RV1 is a varistor, is used for absorbing the spike overvoltage.Power-type NTC themistor of serial connection in power circuit, the surge current in the time of suppressing to start shooting effectively.R1, R2 are the bleeder resistances of X electric capacity.
Also comprise following three kinds of circuit in the power-supply filter:
One, power factor corrector (PFC)
MC33262 is a power factor correction chip reliable and with low cost, and its application circuit as shown in Figure 3.
Civil power obtains Rectified alternating current through power-supply filter and rectifier.When C2 charged to 10V, IC's electric current 1 started working by starting resistance R10.Dc pulse moving voltage after the rectification is failed people multiplier as sampled signal through the 3. pin of IC1 in the dividing potential drop of R5.The dividing potential drop of VD on R6 and WR transported to the anti-phase input end of error amplifier through 1. pin, relatively amplifies direct-flow error voltage of back output with the reference voltage of 2.5V, and also defeated simultaneously people is to multiplier.Electric current by power switch MOSFET is converted to voltage signal on source resistance R9, defeated people is to the 4. pin of IC 1, and compares with the output voltage of multiplier.Pass through the output voltage control IC of multiplier with AC voltage to peak value from zero sinusoidally. the threshold values of pin, thus make the peak current of Q1 follow the tracks of the defeated people's voltage of AC, cause the load of correcting circuit to be resistive.Because the control action of MC33262, make defeated people's electric current tightly follow AC voltage and change, be level and smooth sine wave.Simultaneously, pfc circuit is again a kind of booster type switching power supply, and the power of electromagnetism lamp and luminous flux can not changed with the fluctuation of line voltage.
Two, the inverter of lighting a lamp
Inverter circuit such as Fig. 4, it is transformed to the high-frequency alternating current that uses for velocitron with the high voltage direct current of pfc circuit output.The skilful permission of the CISPR of International Electrotechnical Commission is 2.2MHz-3.0MHz to the frequency range of magnetic field induction standard, and its centre frequency is 2.6MHz.As shown in Figure 6:
PFC output dc voltage after the energized, by R19, R18 is added on the capacitor C 12, and C12 begins charging.When institute's charging voltage on the C12 reached the breakover voltage of trigger tube (DIAC) D8-D16, DIAC transferred conducting state to by shutoff.The stored electric charge of integrating capacitor C12 is added on elementary～winding W20 of oscillation transformer BT1 through DIAC, relies on W22, and two windings of W21 make W-}Q81, and Q82 acquisition amplitude equates, phase phasic difference 180o O, drive signal.Q81 is compelled to turn-off and ends when the Q82 conducting; During the Q81 conducting, Q82 is compelled to again turn-off and ends.
The frequency of oscillation of inverter is by winding W21, the inductance value of W22 and field effect transistor Q81, defeated people's electric capacity and building-out capacitor C81, the C82 of Q82 determine that jointly the resonance frequency of lamp loop network must be identical with the resonance frequency in defeated people loop, and for example: resonance frequency is 2.65MHz.Also will optimize Q81 as possible, the amplitude of Q82 drive signal and waveform make himself power consumption drop to minimum.Diode D8 ' has two effects: the electric charge on the C12 that is used for during forward releasing prevents that inverter circuit from because of " common conducting " phenomenon appears in false triggering, shielding; In the time of oppositely, utilize the reverse current of reverse recovery time to be the defeated people's pumping signal of oscillation transformer.LZ among Fig. 3, C14, C15 are resonant inductance and resonant capacitance, they are important parameters in the design.The startup stage, the equivalent resistance of bulb is very big, Lz, series resonance takes place in C14, C ingeniously, resonant circuit can form the ignition voltage of very high (about 3000V) at the lamp two ends.After velocitron ignites, advance people's normal operating phase, in the foam electric arc equivalent resistance at hundreds of ohms, after lamp current generates, the resonant tank off resonance, C14, the resonance potential on C is skilful drops to the operating voltage of lamp.Lamp is lighted lamp is stablized in the back by Lz arc current.Meanwhile, because the frequency-selective filtering effect of output loop, the electric energy of lighting a lamp is the voltage and current of a cosine wave, and its frequency is the fundamental frequency of pumping signal.
Three, abnormity protection circuit
When occurring that the bulb wiring comes off or during abnormality such as bulb gas leakage, velocitron can not normally start, the resonance circuit of igniting is in resonance condition always, and the 3-5 that the electric current of inverter output increases to normal current doubly.If do not take effective safeguard measure, will cause light a lamp inverter and prime element circuit to burn because of overload, even cause smolder, accident such as explosion.Abnormity protection circuit as shown in Figure 5.
When abnormality: at resonant capacitance C14, the mid point of C15 is drawn the abnormal protection sampled voltage, by capacitor C 16, and the dividing potential drop of C18 and D18, D19; Become control voltage after the R24 rectification, pass through R25, R21 and C19 delay circuit, the direct voltage that on C19, is risen in time, when this voltage just breakdown during greater than the voltage stabilizing value of DZ1, controllable silicon MCR conducting with Q82 grid and ground short circuit, forces half-bridge inversion circuit to quit work by blocking diode D17.And under normal condition, the voltage on the C19 does not also rise to the voltage stabilizing value of DZ1, and lamp has just been lighted, and lamp is lighted the just off resonance of back resonant circuit, thereby DZ1 is in cut-off state always.The numerical value of R20 can not be obtained too big, and its electric current is generally 1-2mA, and can not obtain too big the operate time of protective circuit, is generally 1--2 second.C20, R23 play anti-interference effect, prevent that unidirectional silicon is because of the interference signal misoperation.
The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
