At present, the large power compact type cold cathode-fluorescent lamp of prior art, when adopting sealing printing opacity cell-shell, lamp hole temperature can be up to more than 120 ℃, and at this moment, if use liquid mercury in the fluorescent tube, then luminous efficiency can obviously descend because of mercury vapor pressure is too high.For this reason, generally adopt the amalgam of controlled mercury vapor pressure to do the mercury source, thereby guarantee when lamp hole temperature is higher, mercury is not pressed and can be surpassed the certain limit that best mercury is pressed in the pipe, thereby guarantees that high-power lamp has higher luminous efficiency.But the optimum working temperature scope of amalgam is high more, and its mercury is at normal temperatures pressed just low more, and promptly when the lamp power connection, lamp brightness meeting is low very low because of mercury vapour.Simultaneously, the interior mercury of fluorescent tube presses the temperature with lamp hole temperature and amalgam to rise and slowly rise, and therefore, a bright speed of lamp is very slow.For this reason, in the hot cathode compact fluorescent lamp, near cathode filament, place an auxilliary amalgam usually, for example, coated has the nickel screen of indium, behind the lamp power connection, filament temperature is up to 900 ℃, under the heating of filament high temperature, auxilliary amalgam heats up rapidly, and the mercury that is adsorbed on the indium is discharged rapidly, make mercury pressure rising rapidly in the fluorescent tube, thereby it is bright that lamp is risen fast.Yet in cold-cathode fluorescence lamp, do not have the heated filament negative electrode of working temperature, can't adopt the auxilliary amalgam of aforesaid way heating, thereby it is often slower to play bright speed up to 900 ℃.
The objective of the invention is to overcome the deficiency of above-mentioned existence, and provide a kind of can be made into to play bright large power compact type cold cathode-fluorescent lamp fast.
The objective of the invention is to finish by following technical solution, it comprises at least one cathode fluorescent tube, printing opacity cell-shell, driver and shell thereof, a lamp holder; At least two electrodes and at least one main amalgam and at least one auxilliary amalgam are arranged in the described fluorescent tube, and main amalgam is positioned at the proper temperature place of lamp, is used to control the mercury vapor pressure in the fluorescent tube, makes lamp obtain best luminous efficiency; Auxilliary amalgam is positioned at the place that the easy rising of fluorescent tube temperature can't produce metal sputtering, and behind the lamp power connection, auxilliary amalgam heats up rapidly and discharges mercury, and it is bright that lamp is risen rapidly, thereby played bright high-power compacting fluorescent lamp soon.
Described main amalgam can be bismuth indium amalgam, bismuth slicker solder amalgam or other amalgam, is positioned at the lamp hole temperature lower, for example, near the lower drive enclosure top of the temperature electrode, the lamp of different capacity, different cell-shell size and structure can be selected different amalgam for use, to obtain best luminous efficiency.
Described auxilliary amalgam is one thisly at high temperature to release the amalgam that mercury, low temperature are inhaled mercury down, and for example, coated has the material of releasing suction mercury mercury low temperature under under nickel screen, stainless steel cloth or other high temperature of indium.It is positioned at fluorescent tube and is rapidly heated easily and releases the place that mercury can't produce metal sputtering, and it is bright to be used to make lamp to rise fast.For example be wrapped on the electrode outer surface or be placed in the bucket of garden and and electrode insulation, or be placed in the preceding discharge channel of electrode, or be placed on other discharge channel place in the fluorescent tube, or directly material coateds such as indiums on the electrode outer surface, or the powder distribution of materials such as indium in luminous bisque, also can above several modes use simultaneously.
But coated has electronic emission material on the inner surface of described garden bucket, to reduce cathode drop, improves luminous efficiency; At this moment described electrode has enough big surface area, for example electrode emission current＜0.2mA/mm
2, can be to guarantee electronic emission material because of the electrode sputter does not consume very soon, thus the high efficiency of obtaining, long-life lamp.
