Description
Technical field
The utility model belongs to the photoelectric source technical field, is specifically related to a kind of electricity-saving lamp stem stem of built-in amalgam block piece.
Background technology
Compact fluorescent lamp (hereinafter to be referred as electricity-saving lamp) is one of best light source of eliminating the poor efficiency illuminating product." about prevent to use the instruction of some harmful substance in electric equipment " according to environmental requirement promulgation is the ROHS instruction, must adopt solid-state mercury (amalgam) to substitute traditional liquid mercury during electricity-saving lamp is produced, and limits the quantity of and be lower than 5mg.When using amalgam to produce electricity-saving lamp, Auxiliary amalgam (sheet) is welded on the filament below of stem stem, and main amalgam must be placed on a certain fixed position in the stem stem blast pipe, guarantees that promptly the distance between main amalgam and the filament is a fixed value.Under the filament pre-heating temperature, the mercury vapour that Auxiliary amalgam discharges is pressed and need be controlled in certain scope, usually account for 0.2% of ar pressure, utilize the Penning effect principle to reduce the starting resistor requirement of lamp, reach loss that reduces electronic emission material on the filament and the purpose that prolongs the life-span of lamp.After lamp started, the temperature at each position rose in the lamp, and the mercury amount that mercury amount that this moment, main amalgam discharged and Auxiliary amalgam discharge has guaranteed the best mercury atmospheric pressure value that different tube diameters requires together, and the light efficiency of lamp reaches maximum from making.
Utility model patent CN201000874 and CN201181686 disclose the electricity-saving lamp stem stem that adopts the glass exhaust tube flattening method to make, when using, reality finds to still have amalgam to be subjected to displacement phenomenon, its reason is that the amalgam solid mercury under the influence of filament temperature behind the release mercury can be out of shape, even can roll in the fluorescent tube from steam vent.
Utility model patent CN201465996U discloses a kind of method of shelving the main amalgam in location of woven wire in blast pipe, but do to be shifted under the impact of time spent wire mesh sheet at main amalgam as external force, can't guarantee the reliably spacing of main amalgam, distance can change between promptly main amalgam and the filament, when main amalgam displacement when the filament, under the effect of filament temperature, can influence Penning effect, make the light efficiency of fluorescent tube reduce the lost of life.
Summary of the invention
The utility model provides and can guarantee the normal toggle speed of fluorescent tube, the light efficiency and the useful life of having improved fluorescent tube to the electricity-saving lamp stem stem of the built-in amalgam block piece of the correct spacing and permanent location of main amalgam.
The utility model has adopted following technical scheme: a kind of electricity-saving lamp stem stem of built-in amalgam block piece, it is by oviduct, blast pipe and sealing-in seal wire sintering form, described blast pipe is arranged in oviduct, described blast pipe is provided with steam vent, on the blast pipe between the steam vent and the loudspeaker mouth of pipe, be provided with, following two place's indents, be provided with the amalgam block piece in the blast pipe passage in two between the recess, main amalgam is positioned at the outside of recess under the blast pipe passage, described amalgam block piece and main amalgam by the spacing moving type that is of indent, are discharged and are charged into the gas that guarantees blast pipe in the blast pipe passage.
The interior recess of upper and lower blast pipe can be a concave side wall in the utility model, also can two pairs of wall while indents.The position that blast pipe two concaves can be positioned at same perpendicular, also can be positioned at different perpendiculars to.
The blast pipe passage ovalize of recess in described, described amalgam block piece is cylindric, the diameter of described amalgam block piece and main amalgam is less than the major axis of described oval-shaped passageway, greater than the minor axis of oval-shaped passageway.
The material of described block piece is glass, pottery or metal.
The beneficial effects of the utility model are as follows: blast pipe is provided with down indent, main amalgam is undertaken spacing by following indent, the distance that is maintained fixed between main amalgam and the filament, main simultaneously amalgam is active state in blast pipe, can not influence the normal exhaust and the inflation of electricity-saving lamp, thereby guarantee that electricity-saving lamp obtains stable mercury vapour and presses, it is constant that the toggle speed of fluorescent tube keeps, and improved the light efficiency of fluorescent tube.After electricity-saving lamp service time is long slightly, main amalgam discharges mercury gradually, the amalgam volume can diminish gradually, cause amalgam to skid off from interior recess, but owing to be provided with the amalgam block piece in the blast pipe passage between the recess in two, the amalgam block piece can prevent that the amalgam that diminishes from continuing to be subjected to displacement, and realizes the permanent location of main amalgam, the useful life of having improved electricity-saving lamp.One-sided wall of blast pipe or two inwall indents can, as long as can be to main amalgam and the spacing normal use that just can guarantee electricity-saving lamp of amalgam block piece.The position that upper and lower two places of blast pipe concave can be positioned at same perpendicular, also can be positioned at different perpendiculars, as long as the displacement of main amalgam that can block and amalgam block piece can guarantee again that exhaust and inlet channel are unimpeded to get final product.The material of described block piece can be glass, pottery or metal, only otherwise poisonous chemical reaction takes place just with mercuryvapour.The block piece of employing cylindrical structure can guarantee the circulation of gas better, and the space of cylinder side can be used as gas passage.
