Description
The application is that application number is 200910153707.5 divisional application.
Technical field
The present invention relates to a kind of power saving fluorescent lamp, especially relate to a kind of quickly-starting power-saving fluorescent lamp with cover.
Background technology
Enter after 21 century, along with the continuous enhancing of people's " energy-conservation ", " environmental protection " consciousness, power saving fluorescent lamp is subject to people and praises highly widely.Particularly the profile band cover type power saving fluorescent lamp more similar with incandescent lamp, just receives concern especially behind the market that certainly exposes.Its growth momentum is powerful in recent years, is expected to become the main flow in market.But there is a general problem in band cover power saving fluorescent lamp: climbs slow, after lamp is lighted, need the long period just can reach specified brightness.The phenomenon of this " climbing slow " is to be determined by the inherent feature of band cover power saving fluorescent lamp.Because increased a glass outer cover outward at fluorescent tube, so heat radiation is subject to appreciable impact, the temperature of fluorescent tube exceeds much when not being with cover.For this low-pressure mercury discharge lamp of power saving fluorescent lamp, in order to obtain high light efficiency, the mercury vapor pressure in fluorescent tube must maintain on a rational numerical value.For this reason, in the time that lamp works is in hot environment, only select high temperature mercury alloy as the source that mercury vapour is provided.But the temperature of turning on light when initial in fluorescent tube is lower, the mercury vapor pressure that therefore high temperature mercury alloy can provide is also very low, and the brightness of lamp is also therefore very low.Only, along with the temperature of fluorescent tube progressively raises, in fluorescent tube, the luminous intensity of mercury vapor pressure and fluorescent tube could progressively improve.Conventionally, sustainable 30 seconds to 2 minutes of the process of climbing after switching on cover type power saving fluorescent lamp, can not " open bright " as incandescent lamp.Having lower cold junction temperature realizes and has lighted fast very important meaning band cover electricity-saving lamp.Because the brightness of fluorescent tube is affected by its inner mercury vapor pressure, and mercury vapor pressure is subject to the control of fluorescent tube cold junction temperature, so cold junction temperature can finally affect the brightness of fluorescent tube.Band cover type power saving fluorescent lamp is in the time of work, because glass bulb has stopped the diffusion of fluorescent tube heat, its fluorescent tube internal and external temperature, than the electricity-saving lamp with cover (being called for short " naked lamp ") is high not a lot, therefore can only obtain a suitable mercury vapor pressure that can ensure light efficiency with high-temperature amalgam.But after fluorescent tube is lighted, its temperature and mercury vapor pressure must experience a process that progressively raises, finally tends towards stability, meanwhile the luminous flux of fluorescent tube also will be followed a process of slowly climbing of mercury vapor pressure experience.Said process, if defined with the 80% needed time that reaches nominal light flux, generally at 60 seconds---between-120 seconds.For a lot of application scenarios, this is very inconvenient even unacceptable.
In a word, using high-temperature amalgam is to cause normal tape cover type power saving fluorescent lamp can not realize the basic reason of lighting fast.Must create an enough low cold junction temperature environment for this reason and make to be with cover type power saving fluorescent lamp can use Low temp amalgam, make with the faster light object of cover type power saving fluorescent lamp thereby reach.
Summary of the invention
It is enough low that technical problem to be solved by this invention is to provide a kind of cold junction temperature environment, can use Low temp amalgam, thereby reach faster light quickly-starting power-saving fluorescent lamp with cover.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of quickly-starting power-saving fluorescent lamp with cover, comprise lamp adapter assembly, fluorescent tube and glass case, the front end of described fluorescent tube is provided with the cold junction of a projection, described cold junction and described cloche shell joint touch, the surrounding of described cold junction outside is provided with adiabatic gum, in described cold junction, be provided with mercuryvapour source, described cold junction comprises a prominent bubble, on described prominent bubble, be provided with the third electrode through described prominent bubble wall, described third electrode the inner is stretched in described fluorescent tube, the outer end of described third electrode contacts with described glass case laminating, described mercuryvapour source sticks on described third electrode.
Described third electrode is two Dumet wire.
Compared with prior art, the invention has the advantages that the cold junction that a projection is artificially set at the front end of fluorescent tube, end and the cloche shell joint of cold junction are touched, and around cold junction outside, adiabatic gum is set, mercuryvapour source is arranged in cold junction, though make fluorescent tube be operated in hot environment, but can use low temperature mercuryvapour source (if working point is the spherical Bi-Sn-Hg mercury alloy ball of 1 millimeter lower than the diameter of 55 degree), and the light efficiency of guaranteeing fluorescent lamp is unaffected, it has fundamentally solved with the cover type power saving fluorescent lamp slower shortcoming of climbing, can make to be with cover type power saving fluorescent lamp to be realized lights fast, and being set around cold junction outside, adiabatic gum can make the hot-air in cold junction and glass case keep apart, stop cold junction heat dissipation channel by hot air, thereby can form larger temperature gradient on heat dissipation channel, and radiating effect is strengthened, therefore cold junction temperature is also further reduced, steep the third electrode of wall through dashing forward and be provided with on prominent bubble, third electrode the inner is stretched in fluorescent tube, the outer end of third electrode contacts with the laminating of glass case, amalgam sticks on third electrode, third electrode has formed cold junction heat dissipation channel, it can absorb the heat at this cold junction place, is then reached outer end, then by touching heat is passed on glass case and dispelled the heat with cloche shell joint, on the other hand, third electrode also has following effect: (a) in the time that mercuryvapour source is used liquid amalgam, have the effect of fixed support: when general fluorescent tube generation mechanical movement, the liquid amalgam particle of enclosing can roll back and forth at phosphor surface, this likely causes phosphor powder layer to come off, thereby have influence on luminous flux and lamp tube service life, and stick to third electrode place after the liquid amalgam of inclosure can being softened in the time of lamp processed, can effectively prevent that like this liquid amalgam occurrence positions from rolling, (b) further reduce mercury vapor pressure: in the fluorescent tube interior zone of special construction, third electrode is on the ion plasma marginal belt in fluorescent tube, its outside forms one deck " shell " because of the interaction of the charge carrier of electrode and ion plasma, the electrochemical action of the generation on the interface of " shell ", to further reduce near the concentration of charged mercury vapour electrode, thereby regulate mercuryvapour source mercury vapor pressure around, (c) reduce the effect that fluorescent tube cold junction inner surface tube wall is loaded: the quantity of the negative electrical charge adsorbing on cold junction inner surface phosphor powder layer can be effectively reduced at the tip that is positioned at the third electrode of fluorescent tube cold junction inside, thereby reduce the temperature of fluorescent tube cold junction inner surface tube wall load further reduction cold junction inside, third electrode is two Dumet wire, after in the time of lamp processed, the liquid amalgam of inclosure being softened, sticks on Dumet wire, can prevent that amalgam from rolling.
