Description
Technical field
The present invention relates to field of illumination lamp technology, refer more particularly to a kind of electrodeless lamp of physical isolation formula of avoiding so-called " electrodeless lamp starts Disturbance in Power Net ".
Background technology
HF lamp without electrodes is the integrated application power electronics, and plasma is learned, the new high-tech product that the up-to-date scientific and technological achievements in field such as magnetic material are developed out.Be the high light efficiency of a kind of representative lighting technology, the new type light source of high-color rendering future thrust.The illumination expert is called " beginning of the new revolution of lighting field " with this green illumination new light sources.From the invention of " electrodeless lamp " so far, more than 100 year history has been arranged, during the road of passing by, difficult and tortuous.And China begins research and development and produces " electrodeless lamp ", also more than ten years.
Electric light is from having filament to no filament, and the lamp life-span is greatly improved, because filament and electrode life are short, is the main cause that influences lamp life, and therefore, people expect " no filament " naturally, the desirable light fixture of " electrodeless ".Therefore electrodeless lamp arises at the historic moment.
Electrodeless lamp is not owing to there is electrode, filament, and theoretical calculate, its life-span can reach more than 1,000,000 hours.This is the great advantage of " electrodeless lamp ", but up to the present all adopts owing to the whole world: " Philip structure " (this structure is asked for an interview Fig. 1) just do not have isolated electrodeless lamp technology as ballast basic structure.This technology causes electrodeless lamp to produce on using:
1, the very long problem of short lamp tube service life of electroless lamp ballasting device life-span:
Electrodeless lamp utilizes high-speed ion impact fluorescence powder luminous, and will make the solid mercury in the fluorescent tube become the high-frequency and high-voltage (some modulating voltage) that ion needs one make its snowslide, and it is bright never not having this lamp." Philip structure " utilizes fluorescent tube coil formation in parallel with electric capacity resonance (LC resonance) to make it reach a modulating voltage, and the fluorescent tube coil presented high-impedance state when condition of resonance was cold lamp, uses as a lamp just to be in the middle of the off resonance when bright.The electric capacity of LC has certain withstand voltage, and electric capacity is breakdown when voltage surpasses its withstand voltage.Resonance can make voltage constantly increase that voltage does not constantly raise as long as lamp works, and the energy that ion avalanche needed in the fluorescent tube when ambient temperature was low can strengthen.The characteristics of resonance are the increases of uncontrollable voltage.So short lamp tube service life of electroless lamp ballasting device life-span is very long.
2, no isolated electrodeless lantern festival produces the problem of disturbing to electrical network:
It is that an AC becomes the process that DC becomes AC again not have isolated electrodeless lamp employing Philip structure, and last AC voltage does not have isolation will return electrical network, and it is even more serious to the interference of electrical network especially to put modulating voltage.I did will not have isolated electrodeless lamp and computer and be inserted in test in the same supply socket, open no isolated electrodeless lamp after opening computer earlier, and computer must " crash ", such test ten times repeatedly, and none is not like this.Sort circuit has increased filtering in the place of power supply input in fact, but still can't suppress its interference to electrical network.
3, the powerful heat dissipation problem of no isolated electrodeless lamp:
Have isolated electrodeless lamp utilization up and down the driven MOS pipe produce square wave, enter in the LC resonant tank that electrodeless lamp solenoid and electric capacity constitutes by capacitive coupling again.The string wave power loss of becoming a full member of powerful like this square wave is very big, and it can cause electrodeless lamp solenoid heating, and heating had both influenced luminous efficiency and also influenced its life-span simultaneously.Can only so just not cause the increasing of metal-oxide-semiconductor switching loss to cause heating with the transformer isolation drive-type thereby also have owing to there is the driving of isolating metal-oxide-semiconductor, this problem also suppressing the high-power of electrodeless lamp.Heating simultaneously also directly makes its lifetime.
Yet electrodeless light fixture has advantages such as the at present high light line of luminous efficiency is soft, will be the optimal product of the 4th generation light source if can overcome above-mentioned shortcoming.
Based on several weak points of above-mentioned existing electrodeless lamp, the inventor has designed the present invention's " isolated electrodeless lamp ".
Summary of the invention
