Description
Technical field
The utility model relates to electronics circulation accelerating type plasma fluorescent lamp, belongs to lighting technical field.
Background technology
Common Non-polarized lamp is when work, inspire energy field by magnetic field or electric field, make the mercury evaporation form mercury vapour, and by the ionizing energy field, the heating mercury vapour, thus make mercury atom in the situation that accelerated collision mutually by energy field, produce a large amount of electronics and cation, and excited ultraviolet in this course, ultraviolet ray inspires visible ray after shining the fluorescent material be applied on tube wall.As the patent publication No. patent that is CN101894732.But the shortcoming of this light fixture maximum is, mercury is the material with certain toxicity, and fluorescent tube is made by glass mostly, very easily broken, once fragmentation appears in tube glass, mercury vapour can leak, the user is caused damage, and the mercury vapour leaked also easily causes environmental pollution.
The patent that publication No. is CN102543657 discloses a kind of without the mercury Non-polarized lamp, has filled neon and Krypton in fluorescent tube, has avoided the use of mercury.But this patent has only replaced to neon and Krypton by the mercury in original fluorescent tube basically simply at traditional Non-polarized lamp, and dwindle the distance of inner tube and power coupler, made ultraviolet ray and fluorescent material be easier to excite.Although be the use of having avoided mercury, brought new shortcoming, the effect that neon and Krypton are excited in the energy field of traditional structure is less than mercury, therefore the light efficiency of this Non-polarized lamp is low, and because inner tube and power coupler distance is little, can't make high power, poor for applicability.
The utility model content
The utility model, for solving the prior art problem, provides a kind of without mercury, and possesses the electronics circulation accelerating type plasma fluorescent lamp of high light effect and Energy Efficiency Ratio.
The technical solution of the utility model is: electronics circulation accelerating type plasma fluorescent lamp, the magnetic control chamber of being made by transparent material that comprises the emitting cavity of the sealing of being made by transparent material and be arranged at described emitting cavity inside and mutually seal with described emitting cavity, be filled with inert gas in described emitting cavity, described magnetic control chamber is cylindrical, in this magnetic control chamber, is provided with driver module; Described driver module comprises the line bag of two certain distances that interfix and have each other, and described line bag is by forming with the coaxial magnetic core in described magnetic control chamber and at least two group coils that are wound on this magnetic core.
The maximum difference of the Non-polarized lamp that the utility model electronics circulation accelerating type plasma fluorescent lamp and traditional electric field excite is, the utility model adopts electronics circulation synchrotron principle, the High Rotation Speed electromagnetic field that the one equally distributed electric field changed by high frequency excites is set in the magnetic control chamber, and form the magnetic field of High Rotation Speed in emitting cavity, inert gas in emitting cavity is accelerated by this magnetic field, round magnetron, forms eddy current.When inert gas is accelerated to certain speed, can produce a large amount of charge carriers, while being initial condition, inert gas contains a small amount of free electron, after free electron is subject to accelerating neutral gas atom of rear collision, the latter is ionized, thereby produce a new free electron and a cation that quality is larger, cation and new free electron are reversed respectively acceleration, continue the more neutral gas atom of collision, produce more cation and more free electron, the avalanche effect of generation current thus, form electric arc, electric arc ionization inert gas, produce a large amount of ultraviolet ray and white, blue, purple light, the probability of simultaneously impelling the atom-exciting of inert gas to return to ground state is surged, produce more electric arc.Because adopting by magnetic field, fluorescent lamp of the present utility model accelerates inert gas, and make free electron self-excitation in inert gas produce electric arc and ionize inert gas, until dynamic equilibrium, therefore the utility model can be in the situation that consume less electrical energy, can produce a large amount of electric arc, the ionization inert gas, produce a large amount of ultraviolet rays and visible ray, and Energy Efficiency Ratio is high.And the Electric and magnetic fields that high speed of the present utility model changes is synchronized with gas circulating in the course of the work, therefore in emitting cavity of the present utility model, probability, scope and the density of electron stream and cation shock intert-gas atoms all obtain larger raising, greatly strengthened the intensity of the interior electron stream of emitting cavity and cation stream, thereby effectively promote discharge rate, increase arc density, light efficiency promotes successful.Simultaneously, do not use mercury in lamp body of the present utility model, eliminated the pollution to environment, environment protecting is good.
