Abstract
The invention relates to a method for injecting mercury for energy-saving light tubes, relating to the manufacturing field of energy-saving lights. The technical scheme adopted by the invention achieves the purpose of accurate mercury injection by the following steps of: (1) adding a certain amount of amalgam to a closed end, such as the end B of a light tube; (2) heating the light tube to volatilize the mercury to enter the light tube; (3) and stumping and closing the end B with amalgam residues at a point A when injecting the mercury. The invention has the advantages that, the quality is controlled by accurately injecting the mercury for naked lights, and liquid mercury can be directly used after selecting a long exhaust tube for hood lights, thereby not only solving the problem of low lighting with the amalgam, but also saving the cost.
Description
Technical field
The present invention relates to electricity-saving lamp and make field, particularly a kind of method for injecting mercury of power saving fluorescent lamps.
Background technology
Along with electricity-saving lamp more and more is used, people also just more and more pay close attention to the problem of the mercury in the electricity-saving lamp, in the prior art, in electricity-saving lamp, use mercury to be still inevitably, but the toxicity of mercury equally also is inevitable, therefore, how under the prerequisite that guarantees the electricity-saving lamp quality, less with mercury with make good use of mercury, just become the problem of our research. do not having on the cover electricity-saving lamp, in the prior art usually usefulness be liquid mercury, for friendly environmental protection, electricity-saving lamp is now only used the mercury about 1.8 milligrams, just become big problem and how can accurately annotate mercury, the instability of mercury content has caused the instability of product quality. and for the cover lamp is arranged, because tube wall heat load height, prior art often adopts amalgam, annotate the mercury amount though use amalgam to control, but the problem that " bright slowly " arranged. also have and want to use liquid mercury by bringing in long regulation of exhaust gas refrigeration, but can not accurately annotate mercury eventually when annotating mercury and can't solve and abandon because of the adhesion of elongated tubular makes liquid mercury be difficult to uniform problem, at last also can only utilize long blast pipe to select the amalgam of some LMPs with reduce cost (2007200675534), in addition, if when using liquid mercury, liquid mercury skewness in fluorescent tube also can influence luminous mass.
Summary of the invention
Technical problem to be solved by this invention is how the cover lamp to be arranged and do not having the problem of accurately injecting liquid mercury on the cover lamp, the technical solution adopted in the present invention is at notes mercury following step to be arranged, (1) presses Fig. 1 and add a certain amount of amalgam at the blind end such as the B end of fluorescent tube, (2) fluorescent tube is heated make mercury volatilization enter fluorescent tube, (3) the B end that will leave the amalgam residue is clipped and is sealed at the A point. and owing to what we injected in the first step is amalgam, therefore we are easy to control its injection rate, make the mercury volatilization with certain temperature heating regular hour then, evaporate into lamp equably among fluorescent tube, to leave the part of amalgam residue then clips and seals at [A] end. at this moment, we have been exactly liquid mercury to the actual injection of fluorescent tube, and deduct the residue amount with the amalgam amount of injecting, just can obtain the liquid mercury amount of our actual injection. as for heating-up temperature, should decide on different amalgam, alloy as Hg and Ti, make Hg volatilization in principle and the nonvolatile temperature of Ti all is fine, see that specifically technology of requirement selection is just passable, because these are normal practice technology, here just do not given unnecessary details, where unimportant on earth as for the A place, it is just passable to clip residue more conveniently.. for there not being the cover lamp, the bright effect of this law is to control quality well by accurate notes mercury, and for the cover lamp is arranged, after having selected long blast pipe routinely, (long blast pipe refer generally to 20mm above) needn't re-use amalgam, directly can use liquid mercury, does so not only thoroughly to have solved and use amalgam " bright must be slowly " problem, and saved cost, its progressive highly significant. (long blast pipe refers generally to more than the 16mm)
Description of drawings
Fig. 1 is a schematic diagram of the present invention, wherein A for can clip residue certain a bit, B is for adding a blind end of amalgam, C is the blast pipe of the other end, D is a lampshade, E is a fluorescent tube.Fig. 2 is the schematic diagram of the present invention after the A point is clipped residue.
Embodiment
Embodiment 1 choosing joint does not have one of cover power saving fluorescent lamps, it is mercurous 30% that at one end 7 milligrams of amalgam that Hg and Ti form inject in portion, and heating makes the mercury volatilization, and an end that leaves the amalgam residue is clipped and sealed, claim 5.2 milligrams of residues, can draw has 1.8 milligrams of liquid mercury in the fluorescent tube.
Embodiment 2 choosings have one of cover power saving fluorescent lamps, there is long blast pipe C to select 25mm as Fig. 1, at one end the amalgam of the B of portion injection Hg and Ti composition is 7 milligrams mercurous 30%, heating makes the mercury volatilization, an end that leaves the amalgam residue is clipped and sealed at the A place, claim 5.2 milligrams of residues, can draw has 1.8 milligrams of liquid mercury in the fluorescent tube, be mounted to whole lamp and conform to quality requirements fully through using.
Claims (3)
1. the method for injecting mercury of a power saving fluorescent lamps, it is characterized in that mainly by forming by following several steps, (1) blind end at fluorescent tube adds a certain amount of amalgam as [B] end, (2) fluorescent tube is heated make mercury volatilization enter fluorescent tube, (3) will be left [B] end parts of amalgam residue and locate to clip and seal at [A].
2. method for injecting mercury according to claim 1,, it is characterized in that being used to that the notes mercury that covers power saving fluorescent lamps is arranged.
3. method for injecting mercury according to claim 2,, it is characterized in that being used to containing the notes mercury that the cover power saving fluorescent lamps is arranged of long blast pipe.
