Description
Technical field
The present invention relates to the high-voltage gas discharging light trigger, specifically relate to a kind of high-frequency power supply type trigger that Metal halogen lamp starts that is used for.
Background technology
The technology that present high-voltage gas discharging light generally uses with electronic trigger is a pulse superimposed type trigger.The pulse voltage of this trigger is very high, generally at 4-5kV.Such high-voltage pulse can cause the sputter of lamp electrode, particularly is subjected to the high-voltage pulse effect under the situation that bulb can not start smoothly for a long time, can produce relatively its life-span to seriously influence; When the high-amplitude pulse trigger starts Metal halogen lamp, the electric light source expert all points out in their achievement in research: relatively good with low amplitude, broad pulse flip-flop toggle Metal halogen lamp, and influencing life-span of Metal halogen lamp with high-amplitude pulse meeting, especially U.S. standard gold halogen lamp more is not suitable for using the high-amplitude pulse enable.Experiment showed, with Inductive ballast+high-amplitude pulse trigger and light a lamp that the life-span of bulb is reduced 20-30% than lighting a lamp with leakage transformer+capacitor, wherein except the voltage ripple of power network factor, the high-amplitude pulse is a key factor to the influence of electrode.For realizing that starting Metal halogen lamp with low amplitude pulse (0.6-0.8kV or 0.6-1.0kV) had once done a lot of effort in the mode of lighting a lamp that replaces leakage transformer to add capacitor, the for example rich FCD-I that reaches, Philips's SI-51 trigger all belong to the low amplitude pulse, but owing to all be to utilize electronic switch to obtain the capacitor energy storage to realize the voltage on the capacitor and the technical scheme of supply voltage addition, the open circuit voltage that is obtained is not only on the low side, also can be unstable because of voltage ripple of power network, so practical application effect and bad.At present, the overwhelming majority remains with Inductive ballast and increases the amplitude pulses trigger and leakage transformer adds two kinds of modes of lighting a lamp of capacitor.We know, it should also be a kind of relatively mode of lighting a lamp of success that Inductive ballast increases that the amplitude pulses trigger lights a lamp, but truly have many weak points, for example, under the situation that bulb can not start smoothly, be subjected to the high-amplitude impulse action for a long time, can produce certain influence to its life-span, that have even also relatively more serious; Secondly high-amplitude pulse is subjected to the influence of the industrial grade of lead and distributed capacitance very big, and it is short to trigger distance, generally has only 0.5-1.5 rice.Leakage transformer+capacitor mode of lighting a lamp is to do something against one's will in the occasion of 220V power supply, though it has some special advantages, and is low as pulse amplitude, bulb power is subjected to voltage ripple of power network little, favourable to bulb life, but the cost height, the expense electricity be its significant disadvantages; Next leakage transformer manufacturing process more complicated, homogeneity of product is relatively poor, bulb is required than higher, thereby influence bulb manufacturing qualification rate.
The second, also corresponding higher to the requirement of withstand voltage of other electrical equipment such as lamp holder, lead etc. in the system, also can be because of the industrial grade and the distributed capacitance size of lead, influence is to the startup of lamp; Secondly, though because pulse amplitude is high, and pulse duration is very narrow, so it is very short to trigger distance; In addition, high voltage pulse sparking can be sent the whip sound, and this can upset people's mood in occasions such as industrial and mineral workshop, markets, influences work, sometimes even can have an accident.Therefore, design, making a kind of both favourablely to bulb life, good startability is arranged again, can be the problem that prior art need solve with low-voltage (0.6-0.8kV or the 0.6-1.0kV) trigger of Metal halogen lamp optimum Match.
Summary of the invention
Technical problem to be solved by this invention is at the deficiencies in the prior art, to provide a kind of low amplitude, broad pulse high-frequency power supply type trigger that is used for high-voltage gas discharging light, to reach the raising startability, the purpose of prolongation bulb service life.
Can recognize from the voltage-current characteristic of Metal halogen lamp, when 0.6-0.8kV, can enter glow discharging process.So, why can not effectively light lamp reliably with the low amplitude pulse trigger of 0.6-1.0kV?
This is one is worth the conscientiously problem of research.If this problem has been made clear, design, make a kind of can just can accomplishing certainly with low amplitude pulse (0.6-0.8kV or the 0.6-1.0kV) trigger of Metal halogen lamp optimum Match.Be with this problem, by having done a large amount of experiments.Found through experiments, between pulse amplitude and the open circuit voltage confidential relation is arranged when Metal halogen lamp starts, as shown in Figure 4.Though its mechanism is pulse can the active electrode emitting electrons, enters glow discharging process, if there are not enough follow-up energy supports can not enter the arc discharge process.This enough follow-up energy is exactly open circuit voltage (or equivalent open circuit voltage).Find also that in experiment the pulse of broad can have lower amplitude.Further research knows that the pulse of broad comes down to have promoted equivalent open circuit voltage.Can clearly be seen that from Fig. 4: open circuit voltage is high more, and desired pulse amplitude is low more; If open circuit voltage greater than 0.6kV, does not even want pulse can light lamp yet.At present, the supply voltage great majority that Metal halogen lamp is suitable for are 220V, generally also require can start when 198V, and open circuit voltage at this moment is 0.28-0.31kV just.Have only the high-amplitude pulse trigger of 1 μ S for pulse duration, the lifting that makes its open circuit voltage is inappreciable.Therefore, as can be seen from Figure 4, open circuit voltage starts Metal halogen lamp when 0.28-0.31kV to need pulse amplitude be 4.0-5.0kV.Because the pulse of broad can promote equivalent open circuit voltage, so the pulse of broad can have lower amplitude.But, special attention should be that lower amplitude must be corresponding with its equivalent open circuit voltage, otherwise just put the lamp that do not work.The very crux of problem that Here it is.Ignored this strict corresponding relationship when designing the action of low-voltage pulse trigger in the past, so insecure problem occurs starting.It can also be seen that from Fig. 4 if can make stable the rising to more than the 0.5kV of open circuit voltage, pulse amplitude just can be done very lowly (0.6-0.8kV or 0.6-1.0kV), realize perfect condition with low amplitude, broad pulse flip-flop toggle Metal halogen lamp.Can but for the line voltage that has only 220V, how lamp circuit obtain the above open circuit voltage of 0.5kV? because civil power has only 220V, but also require can start Metal halogen lamp when 198V, open circuit voltage at this moment is 0.28-0.31kV just.The first, be impossible if rely on pulse duration to have only the high-amplitude pulse trigger of 1 μ S to promote open circuit voltage; The second, existing low amplitude pulse trigger is because the restriction of design principle is difficult to also accomplish that low pulse amplitude is corresponding with the open circuit voltage of its lifting; The 3rd, it also is very difficult leaning on common Inductive ballast to promote sufficiently high open circuit voltage.Trigger must design with brand new concept, and Here it is to improve open circuit voltage is aim.Designing that this trigger wants can effectively stable lifting open circuit voltage.
