Description
[technical field]
The present invention relates to the LED lighting technical field, relate to a kind of LED fluorescent lamp in particular.
[background technology]
The LED lamp is just becoming the main flow electric light source with its high light efficiency, long-life, high plurality of advantages such as energy-conservation, adopts a plurality of LED lamps to be connected into one or more groups usually, and then is parallel-connected on the dc constant flowing power.And the tame electricity consumption of China is the alternating current of 220V, therefore needs power supply adaptor (industry is commonly called as driving power) that alternating current is converted to constant DC output.Power supply adaptor generally all includes rectifying part, filtering part, power transfer part and constant current control section.Rectification is that alternating current is converted into pulse direct current.Filtering partly is the characteristic of utilizing the electric capacity both end voltage not suddenly change, and pulse direct current is become relatively galvanic current.Power transfer part and constant current control section are by ON-OFF control circuit direct current to be converted into high-frequency ac power, and walking around through rectifying and wave-filtering and current feedback is changed to the constant DC source again.Up to now, have a variety ofly about the power supply adaptor of LED lamp, the electric capacity that its filter circuit adopts substantially all is electrochemical capacitor.But the life-span of electrochemical capacitor is shorter, and the life-span of general electrochemical capacitor has only 0.3 ten thousand hours, high-quality also have only 0.5 to 0.6 ten thousand hour, also be difficult to break through 10,000 hours even special electrochemical capacitor is applied to high temperature.It is reported that the electrochemical capacitor of present global longest-lived is the ruby that Japan produces, its life-span is about 20000 hours, and this needs still to guarantee that environment for use just can reach above-mentioned service life.But, the life-span of LED lamp generally all is 50,000 to 100,000 hours, be far longer than the life-span of electric capacity, according to " wooden barrel principle " as can be known, in the life-span of whole LED fluorescent tube, depend on that the shortest part of life-span in all parts, therefore, the life-span of electric capacity on the power supply adaptor is the greatest factor of restriction whole LED lamp tube service life.But the cost of power supply adaptor only accounts for about 20% of whole LED fluorescent tube cost, yet the electrochemical capacitor that filtering is used only account for whole LED fluorescent tube cost 5% less than, if abandon fluorescent tube because of the electrochemical capacitor fault on the power supply adaptor, can cause great waste, if change or the maintenance power supply adaptor, not only need the professional, and maintenance bothers, wastes time and energy.
For addressing this problem, two kinds of methods are arranged at present, a kind of is that equivalence is replaced, promptly adopt the non-electrolytic capacitor of same electrical capacity to replace electrochemical capacitor, but need several high withstand voltage electric capacity at least in the general driving power, have in addition need withstand voltage 400V, except electrochemical capacitor, be difficult to find other interchangeable electric capacity, therefore, equivalent replacement method is difficult to realize.Also has a kind of method, as application number is CN200810073564.2, the applying date to be the patent of invention that 2008.05.05, name are called the control method of power adapter of LED lamp without electrolysis capacitor, the scm software method is adopted in this invention, replace traditional energy storage electrochemical capacitor with active power electronics method, the constant-current supply of the required burning voltage of LED lamp, constant current is provided with digital mode.Though this method need not to use electrochemical capacitor, its anti-interference is relatively poor, stability is bad, and with high costs, and maintenance difficulties is big.
