Description
Technical field
The utility model relates to a kind of driving power of solid luminous lamp, more particularly, relates to a kind of drive electric power unit of ballast formula LED lamp.
Background technology
The LED semiconductor lighting is the new industry that State Council accelerates cultivation and development strategy.In the recent period, the Department of Science and Technology has worked out " semiconductor lighting development in science and technology " 12 " ad hoc planning ", in the application technical research of the key task of ad hoc planning, has proposed efficient, low-cost, the highly reliable LED driving power of exploitation.This has illustrated the importance of LED driving power in the technology of semiconductor illumination application field.
The LED driving power mainly contains alternating current 220V civil power supply load after commutation inversion is used at present, the rectifier bridge that the most frequently used rectifier system is comprised of 4 diodes is transformed to direct current by alternating current, become again controlled direct current after inversion, supply with the LED lamp.The shortcoming of this method is, the non-linear of DC transfer circuit formed due to diode and electric capacity can produce a large amount of current harmonics and reactive power, causes the pollution of electrical network.This harmonic pollution not only can make the line voltage distorted, but also can cause fault and the damage of power consumption equipment.Therefore, need to take very complicated means that the waveform of input current is approached sinusoidal wave.This complex process can exert an influence to the useful life of LED driving power naturally.LED is widely used with its environmental protection, luminous efficient characteristics, and especially aspect illumination, application is more and more extensive.With regard to current development, what everybody was concerned about the most is the life problems of lamp, and be that lamp user or factory are all seen now, the life-span of lamp is depended on driving power, lamp failure more than 99% is all because driving power causes, the life-span of LED reaches 50 000h, so but the life-span of supporting driving power is only that one of key link that can 10 000h. LED lamp lighting apparatus application is its driving power problem with it.The problem existed for prior art, Chinese patent application publication No. CN102523674A has proposed the brand new technical scheme of the driving power of ballast formula LED lamp, uses the driving power of ballast formula LED lamp to have following advantage:
1, oneself power consumption is little, temperature rise is low, long service life.These characteristics are above-mentioned patented technology advanced places compared with prior art, the little energy efficiency factor that can improve system of oneself power consumption in These characteristics; The low characteristic of temperature rise is particularly important for the LED lamp, what well-known LED lamp was feared most is exactly temperature rise, if the temperature rise of LED lamp is very high, add the high temperature rise driving power, the performance of lamp will sharply descend (prior art is all like this), uses the driving power of ballast formula LED lamp, and the temperature rise Δ t of the element Inductive ballast that it can generate heat can be controlled in 10 degree, the driving power of the LED lamp of this specific character, will improve the combination property of LED lamp greatly; Useful life, because the temperature rise of Inductive ballast is extremely low, useful life that so Inductive ballast has very long (foundation was IEC920 ballast working temperature and concerned chart useful life at least 50 years), capacitor in circuit is according to national GB/T 18504-2001 relevant regulations, and the life-span of its continuous operation is at least 10 years.
2, to meet requirement, the functional reliability of LED lamp fully high for superior performance.The driving power of ballast formula LED lamp has the characteristic of relatively constant electric current and dynamic voltage adjustment, and the function of dynamic voltage adjustment is that underload (as 1 LED lamp) and full load (as nominal load power is a plurality of LED lamps) LED lamp can work.And the driving power of the LED lamp of prior art is due to certain LED because the quality reason of self is damaged thereby form short circuit, its original voltage drop is just married again on other LED lamps, can make other LED lamps also will be because overvoltage damages.Because the element of the driving power rapid wear of ballast formula LED lamp of the present invention is few, the reliability of work will improve greatly.
3 harmonic contents are few.The driving power of ballast formula LED lamp is electric capacity and inductance series circuit, and electric capacity coordinates with inductance, makes the current waveform of circuit approach sine wave, and shape factor is in 1.5 left and right, so harmonic content is few, pollution-free to electrical network.
Yet, the driving power of ballast formula LED lamp also exists some to need perfect place, and the driving power that the patent that is 201220477856.4 as application number is just the ballast formula LED lamp of CN102523674A for public announcement of a patent application number has proposed the corrective measure during in wide variation at input voltage.Because this corrective measure realizes constant current by the switching over capacitor, suppose just not to be discharged input again after the capacitor excision, if just in time the voltage-phase of Shi road electric capacity (C) and the condenser voltage that excises contrary moment, will bear the voltage surpassed at road electric capacity (C) on institute's excision capacitor, maximum even may reach the overvoltage of nearly twice of the magnitude of voltage of electric capacity (C), makes charging current very large.Also have, due to outdoor thunder and lightning, or large load is opened, shutoff, and the surge voltage of voltage clutter and so on, also need to take measures.
