Description
Technical field
The present invention relates to the three-phase LED illumination high-performance rectifying power supply apparatus that LED (light-emitting diode) illumination and electronic curtain are used.
Background technology
The LED lamp is because its luminous efficiency is high, the life-span is long, color rendering is good, be convenient to again the light modulation toning, the series of advantages such as automatic control are encoded in implementation, gain great popularity, range of application is more and more wider, except as indicator light and various electronic curtain, also is widely used in the indoor and outdoor lighting device of various different purposes.Yet in actual applications, especially, also there are many problems in technical at rectifier power source, should cause and show great attention to, if not at the beginning of Popularization And Development the phase controlled and solved, will lead to serious future trouble.
One, the life-span of LED luminous tube and rectifying power supply apparatus does not mate.
The LED luminous tube belongs to direct current small-power low-voltage product, and the use voltage of single luminous tube is for below direct current 3～5V, and power is at present below 5W.With regard to single luminous tube, its life-span is very long, can be over 50,000 hours.Yet the VD that has many products to adopt is higher, and the luminous tube quantity of serial connection is more, due to the dispersiveness of each luminous tube internal resistance parameter, bestows the virtual voltage difference on each luminous tube, the luminous tube that voltage is higher can easily damage.After certain luminous tube damages disconnection, the luminous tube of all the other series connection also all extinguishes.So just greatly reduce reliability and the life-span of integral illumination device.
In addition, electrical network all adopts Alternating Current Power Supply at present, and LED should connect DC power supply.So in the LED lighting device, rectifying power supply apparatus must be arranged.According to currently used conventional art, the DC output end of rectifying power supply apparatus all is equipped with electrolytic capacitor filter.And easily dry Gu damage of the electrolyte in electrochemical capacitor, the life-span is 2-3 usually, 5 years at most.Having formed the LED lamp did not mate with the life-span of rectifying power supply apparatus.All things considered, the fault of LED lighting device 95% comes from rectifying power supply apparatus.
The higher harmonic current too high levels that two, LED lamp rectifying power supply apparatus produces.
In LED lamp rectifying power supply apparatus, the existence of filter capacitor, make the mains side alternating current become many arc impulse waves, contains a large amount of higher harmonic currents.The total harmonic current content of China national Specification LED lighting device alternating current source must not be greater than 33% of first-harmonic (50 hertz/sec) electric current.According to test, its harmonic current total content dispersiveness of the product of different manufacturers is very large, and good product harmonic wave total content can reach 25% left and right of fundamental current, and the overwhelming majority is about 40% left and right of fundamental current, and some product even surpasses 100%.Wherein the triple harmonic current of zero sequence accounts for main component.A large amount of harmonic currents causes the severe contamination to electrical network, can cause accessing that electronic installation in electrical network is burnt, communication signal is disturbed, electric energy loss increases greatly in power circuit.Generally say, in the electrical network that the every increase of harmonic current total content 10% causes, the electric energy loss meeting increases by the 50% electric energy loss amount caused higher than fundamental current.Especially the neutral harmonic current in the three phase mains circuit can superpose by the neutral line, and only this item neutral harmonic current value just may surpass the phase line operating current, if add the uneven fundamental current of three-phase zero sequence, will cause the neutral line seriously to transship.Not only greatly increase electric energy loss and the voltage drop of circuit, once and the neutral line be blown, can lead to serious loss of life or personal injury and electric equipment and damage or fire incident.And most LED lighting device does not take to suppress the effective measures of harmonic wave.If do not add control, such product is widely applied in electrical network at one's discretion, and its consequence is hardly imaginable.
Three, lightning protection properties is poor.
Rectifier diode in LED luminous tube and rectifying power supply apparatus thereof, current stabilization chip etc. all belong to electronic chip, very responsive to thunder and lightning.And current most LED supply unit does not have effective Lighting Protection Measures.(logically) is connected with earth connection with the light fixture metal shell to need in the electronic circuit of supply unit that Zero potential reference is arranged.If lightning arrester is housed on building, when it accepts thunderbolt when (comprising direct lightning strike and induction thunder), powerful lightning current, in lightning-arrest downlead and earthing device inflow place, can cause on earthing device to reach tens thousand of volts with the potential difference between greatly and even surpass more than 200,000 volts.High like this current potential passes on light fixture metal shell (ground connection because the light fixture metal shell needs protection) and electronic circuit by earth connection, then is connected to the transformer neutral point earthing device through AC power line, earth potential counterattack passage while forming thunderbolt.Electronic devices and components must damage undoubtedly.Also all there are same problem in indoor various electronic installation and outdoor illumination.This because the earth potential counterattack of when thunderbolt causes electronic installation to be damaged or fault-free is shut down accident at home and abroad all occurs again and again, however but by public building lightning protection standard and international electromagnetic compatibility standard, ignored.
Four, improve the power factor problem.
The power factor of national Specification LED lighting device must not be lower than 0.9.Power factor is lower, refers to that the reactive power of power consumption equipment consumption is more, and the electric energy loss in the electrical network caused therefrom is just larger.
The principal element that affects LED lighting device power factor height is the harmonic current content that rectifying power supply apparatus produces.Research shows, as long as LED rectifying power supply apparatus harmonic current content can be lower than the setting of national standard, power factor just can be up to standard.So usually will improve the power factor of LED lighting device, always combine with the measure that suppresses the rectifying power supply apparatus harmonic current.Because most of LED lighting device products lack the effective measures of administering harmonic wave, can only additionally increase the capacitor that compensating power is used, capacitor belongs to fallible component, has so not only increased volume and the cost of product, has also reduced reliability.
Five, the current stabilization of rectifying power supply apparatus and efficiency, power saving.
The voltage-current characteristic of LED luminous tube is nonlinear, and line voltage is little when fluctuation is arranged, and the electric current flow through in the LED luminous tube has larger fluctuation, easily causes the damage of luminous tube.Many products seal in current-limiting resistance (or current stabilization chip) in the circuit of luminous tube for this reason, and its numerical value often reaches more than 10% of the total series resistance of light source.
The current ACLED (without the AC power direct-furnish LED module of rectifying device) produced by TaiWan, China and South Korea Seoul gained great popularity, its series limiting resistor consumed power more reaches 20% of lighting device rated power, caloric value and electric energy loss have been increased in rain, reduced efficiency, be unfavorable for energy-conservation.And its DC output end voltage higher (about 200 volts), the LED crystallite pipe of series connection is a lot, as long as wherein any crystallite pipe damages, whole lamp just goes out, reliability is relatively low.Moreover, four rectifying bridge arms that formed by LED crystallite pipe, in service only have two simultaneously conductings, and utilance is not high, with adopting the general-purpose diode bridge rectifier to compare cost, has improved.
Therefore rectifying power supply apparatus is further improved.
