Description
Technical field: belong to electronic circuit and gas discharge technical field
Background technology: high-intensity discharge (High Intensity Discharge-H.I.D) lamp is meant the arc discharge lamp that electric current is big, and high-pressure sodium lamp, high-pressure mercury lamp, high pressure xenon lamp, metal halide lamp etc. are arranged.Its power be 20 watts to last myriawatt, the power of common illuminating H.I.D lamp is 35 watts to 400 watts, these lamps can provide very high radiance, what have has a good color rendering index, is the important light source of present illumination market.Conventional H.I.D lamp work will have match appliance-Inductive ballast, building-out capacitor and electronic trigger.Electronic trigger is that the H.I.D lamp starts and the crucial matching component of operate as normal, and its performance directly affects the startup of H.I.D lamp, make lamp from aura to the electric arc transition, arrive normal steady operation.
The startup of H.I.D lamp need have sufficiently high voltage in moment, makes gas ionization conduction in the lamp, needs enough big electric current and will make the H.I.D lamp can enter the arc discharge operate as normal, therebetween through the glow discharge zone of a high voltage, low current.From gas discharge basic process, how to make the H.I.D lamp from trigger starting, successfully entering arc discharge through glow discharge is that the H.I.D lamp can successfully be lighted a critical process with operate as normal.From lamp circuit, requirement has enough strong electronic trigger can provide suitably, and high pulse voltage can synchronously provide enough strong pulse energy again, make the quick ionization of gas in the H.I.D lamp, allow the arc current in the discharge lamp increase sharply, and effectively from aura to the electric arc transition.
But at present the electronic trigger that adopts has two kinds of modes to start the H.I.D lamp, and a kind of be the high-tension pulse stamp, and another kind is wide spoke degree, low-voltage type, more than jointly the technical barrier of existence be, obtain pulse height, just lost pulse duration.Obtain pulse duration, just lost pulse height, can't satisfy pulse height simultaneously has enough wide pulse duration again.After the fluorescent tube triggering and conducting, lack continuity high voltage level current potential, influence high-intensity discharge lamp and reliably use.
Summary of the invention:
The present invention will provide a kind of trigger that circuit produced that can reliably trigger the method for various high-intensity discharge lamps and constitute in this way.
The technical scheme that the reliable method that triggers various high-intensity discharge lamps is taked is:
(a 1) big electric capacity utilizes civil power to this capacitor charge and discharge characteristic, produces the low-frequency oscillation of broad pulse;
(2) little electric capacity utilize big electric capacity to produce low-frequency oscillation moment, produce a higher-order of oscillation;
(3), implement effective triggering to high-intensity discharge lamp by two kinds of pulses of high and low frequency;
(4) utilize diode characteristic, make alternating voltage before zero crossing, produce back-emf, implement power back-off, obtain reliably to trigger discharge lamp.
The reliable technical scheme that triggers the physical circuit of various high-intensity discharge lamps is:
Adopt at least 8 electronic components to form, by 2 electric capacity, 2 diodes, the autotransformer of 1 band tap, the alternating-current bidirectional conducting diode of 1 high conduction value, 1 resistance and 1 choke are formed.
Concrete connected mode is:
Trigger exit and autotransformer tap and 1 electric capacity one end join, the some of autotransformer tap and choke one end join, another of autotransformer tap partly leading-out end is second exit of trigger, one end of the choke other end and alternating-current bidirectional conducting diode joins, its other end is connected with a capacitance-resistance end of forming parallel connection and the other end of last electric capacity, the capacitance-resistance other end in parallel and an end of 2 positive and negative diodes that join join, and its other end connects the 3rd exit (earth terminal) of trigger.
The electric capacity in parallel with resistance, capacitance is greater than the capacity of the electric capacity that joins with the autotransformer tap.The number of turns of the autotransformer that joins with second exit of trigger is greater than the number of turns of the autotransformer that joins with choke.
After implementing the present invention, because trigger can produce the high amplitude pulse of high frequency, make the quick ionization of gas in the high-intensity discharge lamp, after have the pulse of low frequency wide cut to remove to keep high-intensity discharge lamp bigger conducts energy is arranged, and by diode characteristic, make alternating current before zero crossing, produce back-emf, implement power back-off discharge lamp, thereby make high-intensity discharge lamp can reliably trigger startup, steady operation.

Now in conjunction with the accompanying drawings operation principle of the present invention is explained
Civil power exchanges initial, and load H.I.D lamp needs thousands of volt high pressure, could the conducting fluorescent tube.Voltage is through T2, T1, and C1, the C2 integration, when the magnitude of voltage in the C2 half cycle during greater than trigger tube operating voltage VO, the C2 electric charge is through the SD1 conducting, and producing frequency is the low-frequency pulse voltage of f1.This pulse voltage, input T1, the low-frequency pulse electromotive force that T1 is subjected to excitatory generation electromotive force E1 to boost and obtain thousands of volts through T2, the input fluorescent tube makes fluorescent tube obtain conducting voltage.When the C2 electric charge through T3, SD1 when discharge, the almost nil impedance of C2.C1 is immediately through D1D2 ground connection, constitutes L/C resonance with the T1 that is connected in series, and produces another frequency and be the high-frequency impulse electromotive force input lamp tube electrode that the high-frequency impulse electromotive force E2 of f2 boosts and obtains thousands of volts through T2.This high-frequency energy helps ionisation of gas, reduces flashing potential.Because the C2 discharge, simultaneously, C1T1 just can constitute L/C resonance.F1, f2 comes from the time over the ground together, synchronized oscillation, synchronous fading has produced the energy gain effect.
After fluorescent tube started, trigger was in level state because of the load tube voltage drop stops to produce high pressure.Will zero passage and zero passage not also at alternating voltage, when voltage will be near 0.6～0.7V,, make positive and negative D1 that joins or D2 conducting because of the semiconductor diode characteristic of pressure drop forward.With the capacitor C 2C1 end that diode joins, voltage instantaneous is 0, and the physical characteristic of tandem electric inductance produces back-emf, and T1 produces a self induction electromotive force E3 immediately, and the E3=-L Δ
1/ Δ t boosts through T2, obtains an electromotive force E4 and is input to lamp tube electrode, and when making alternating voltage zero-crossing point, tube load power is compensated.
