Background technology
Xenon flash lamp is widely used in laser sub-marker, laser-beam welding machine, laser beautifying machine.The features such as xenon flash lamp selects high-quality filter ultraviolet quartz tube as fluorescent tube material, and the electrode take high-quality density electrode as xenon lamp, has load capacity strong, and pumping efficiency is high, and laser beam quality is good, and the life-span is long.
But, xenon flash lamp puncture voltage is very high, and representative value is 10kV, or higher, and there is no stable repeatability, give xenon flash lamp application especially the realization of flash effect brought inconvenience.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of drive circuit of realizing the good flash effect of xenon flash lamp, there is feature easy to use simple in structure.
To achieve these goals, the technical solution used in the present invention is:
Realize a drive circuit for the good flash effect of xenon flash lamp, at the outer wall of xenon lamp 1, trigger impulse transformer 2 is set, the secondary level of trigger impulse transformer 2 acts on the outer wall of xenon lamp 1, and the main of trigger impulse transformer 2 is by discharge capacity C
1contact hair device 3, discharge capacity C
1also by discharge resistance R
1ground connection, the positive pole of xenon lamp 1 is connected to power supply by inductance L and protective resistance R, and protective resistance R is also by storage capacitor C and voltage-stabiliser tube D ground connection in parallel, and trigger 3 receives the pulse signal through photoisolator transmission from single-chip microcomputer.
Compared with prior art, the present invention utilizes a capacitor charging of forcing down than breakdown potential that voltage is provided, during work, utilize the high pressure trigger pulse circuit being connected to around on the trigger silk of photoflash lamp outer wall, can obtain stable output, and can produce at short notice very strong light, respond well.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is carried out to more detailed explanation.
As shown in the figure, the present invention is a kind of drive circuit of realizing the good flash effect of xenon flash lamp, at the outer wall of xenon lamp 1, trigger impulse transformer 2 is set, the secondary level of trigger impulse transformer 2 acts on the outer wall of xenon lamp 1, and the main of trigger impulse transformer 2 is by discharge capacity C
1contact hair device 3, discharge capacity C
1also by discharge resistance R
1ground connection, the positive pole of xenon lamp 1 is connected to power supply by inductance L and protective resistance R, and protective resistance R is also by storage capacitor C and voltage-stabiliser tube D ground connection in parallel, and trigger 3 receives the pulse signal through photoisolator transmission from single-chip microcomputer.
The typical trigger impulse voltage of trigger impulse transformer 2 is wide is 1 μ s, and amplitude is 10～20kV.Electricity power supply charges to storage capacitor C, and when the voltage at its two ends reaches preset value, voltage-stabiliser tube D starts working, and makes voltage constant constant.When needs glisten, by Single-chip Controlling trigger 3, discharge capacity C
1through discharge resistance R
1repid discharge, produce heavy current, through trigger impulse transformer 2, in its secondary level, produce the high electric field pulse of volts up to ten thousand, by the gas ionization in xenon lamp 1, the internal resistance of xenon lamp 1 is reduced greatly, the a large amount of electric energy that store in storage capacitor C are emitted by xenon lamp 1 in a short period of time, have just produced strong flash effect.
