Abstract
The invention discloses an electrodeless fluorescent lamp and a manufacturing method thereof. The electrodeless fluorescent lamp mainly comprises an exhaust pipe, a main amalgam, a coupling cavity, a bulb shell and an auxiliary amalgam, wherein a metal pipe is arranged in the exhaust pipe; one end of the metal pipe is a sealed end and the other end of the metal pipe is an opened end; small holes are formed in the metal pipe; a bump is arranged on the middle part of the metal pipe; the outer wall of the metal pipe and the inner wall of the exhaust pipe are tightly wedged through the exhaust pipe after the exhaust pipe is softened by heating; and after the outer end of the exhaust pipe is sealed, the main amalgam is limited in a set space through the metal pipe. The structure that the metal pipe is arranged in the exhaust pipe is adopted, one end of the metal pipe is sealed and the other end of the metal pipe is opened, and a hydrargyrum vapor conveying pipe is formed in a structure that a plurality of small holes are formed in the part close to the sealed end, so the main amalgam required to be fixedly arranged in an electrodeless bulb can be ensured not to flow into the bulb shell after being liquefied at a high temperature, and the exhaust pipe is not blocked in an exhaustion process, so high vacuum degree in the lamp is achieved, and the performance and the quality of the lamp are improved.
Description
Technical field
The present invention relates to a kind of lighting device, particularly relate to a kind of electrodeless florescent lamp and manufacture method thereof.
Background technology
Bulb-shaped integrated electrodeless fluorescent lamp is specular removal, the long-life new type light source that directly can replace conventional incandescent sources use.Electrodeless florescent lamp is also a kind of low-pressure mercury discharge lamp, and the main amalgam that its lamp internal fixtion is installed has high luminous efficiency for controlling mercuryvapour to keep lamp body.Non-polarized lamp with main amalgam more than 110 DEG C time can be converted to liquid state by solid-state, drop in foam thereupon, cause steeping the bad phenomenon such as interior fluorescent material comes off, foam blackout.Existing bulb-shaped Non-polarized lamp is typically employed in blast pipe and beats concave point, and this place's blast pipe internal diameter is reduced, and falls to stop the amalgam be arranged in blast pipe.The method works when amalgam is solid-state at normal temperatures, but amalgam post liquefaction is then invalid.Also there is the method for installing splendid attire amalgam device in advance in blast pipe in addition, the effect preventing liquid mercury from gliding can be played.But above-mentioned two schemes can cause exhaust duct passageway to block, and exhaust velocity slows down, lamp bulb vacuum degree declines, and causes Non-polarized lamp light efficiency and life-span to decline.Particularly can not effectively apply in the Non-polarized lamp of single tracheae.
Summary of the invention
The object of the invention is to for above-mentioned existing problems and deficiency, provide that a kind of structure is simple, processing is convenient, all effectively can apply in single tracheae and twin exhaust pipes, electrodeless florescent lamp and the manufacture method thereof of vacuum degree and the speed of evacuation can't be affected.
Technical scheme of the present invention is achieved in that
LED lamp of the present invention, form primarily of blast pipe, main amalgam, coupling cavity, cell-shell and Auxiliary amalgam, be characterized in that described blast pipe is in-built and be equipped with a metal tube, one end of this metal tube is blind end, and the other end is openend, and metal tube offers aperture, projection is had in the middle part of metal tube, its outer wall and blast pipe inwall are by closely agreeing with after blast pipe thermoplastic, and after being sealed blast pipe outer end, main amalgam is limited in the space of setting by metal tube.
The manufacture method of electrodeless florescent lamp of the present invention is: the metal tube of an external diameter about 1.2 millimeters of hollows is placed in position suitable in blast pipe, after exhaust terminates again by this place's blast pipe together with sealing by fusing in the middle part of metal tube, termination, wherein said metal tube one end is closed, towards the other end opening in foam, there is several aperture near the position of blind end, form mercuryvapour transfer passage.
The present invention is provided with the structure of metal tube in blast pipe owing to adopting, metal tube one end is utilized to close, other end opening, and have the structure of several aperture to form mercuryvapour feed track at the position near blind end, if now main amalgam liquefaction, its flow channel leading to foam is blocked completely, simultaneously because exhaust terminates rear ability closes vent passage, can not impact the speed of evacuation and vacuum degree.Structure of the present invention is simple, and processing is convenient, all can effectively apply in single tracheae and twin exhaust pipes Non-polarized lamp.Thus enable the present invention while guaranteeing that the hard-wired main amalgam of electrodeless bulb domestic demand can not flow in cell-shell after High-temperature Liquefaction, the blast pipe clogging in exhaust process can not be caused, thus obtain good vacuum degree in guarantee lamp, improve performance quality.
Below in conjunction with accompanying drawing, the present invention is further illustrated.

Embodiment
As Figure 1-Figure 4, electrodeless florescent lamp of the present invention and manufacture method thereof, form primarily of blast pipe 1, main amalgam 2, coupling cavity 3, cell-shell 4 and Auxiliary amalgam 5, described blast pipe 1 is in-built is equipped with a metal tube 6, one end of this metal tube 6 is blind end, the other end is openend, metal tube 6 offers aperture 61, projection is had in the middle part of metal tube 6, its outer wall and blast pipe 1 inwall are by closely agreeing with after blast pipe 1 thermoplastic, after being sealed blast pipe 1 outer end, main amalgam 2 is limited in the space of setting by metal tube 6.The present invention is provided with the structure of metal tube 6 in blast pipe 1 owing to adopting, metal tube 6 one end is utilized to close, other end opening, and have the structure of several aperture 61 to form mercuryvapour feed track at the position near blind end, if now main amalgam 2 liquefies, its flow channel leading to foam is blocked completely, simultaneously because exhaust terminates rear ability closes vent passage, can not impact the speed of evacuation and vacuum degree.Structure of the present invention is simple, and processing is convenient, all can effectively apply in single tracheae and twin exhaust pipes Non-polarized lamp.Thus enable the present invention while guaranteeing that the hard-wired main amalgam 2 of electrodeless bulb domestic demand can not flow in cell-shell after High-temperature Liquefaction, blast pipe 1 clogging in exhaust process can not be caused, thus obtain good vacuum degree in guarantee lamp, improve performance quality.
The manufacture method of electrodeless florescent lamp of the present invention is: the metal tube 6 of an external diameter about 1.2 millimeters of hollows is placed in position suitable in blast pipe 1, after exhaust terminates again by this place's blast pipe 1 together with sealing by fusing in the middle part of metal tube 6, termination, wherein said metal tube 6 one end is closed, towards the other end opening in foam, there is several aperture 61 near the position of blind end, form mercuryvapour transfer passage.
The present invention is described by embodiment, but the present invention is not construed as limiting, with reference to description of the invention, other changes of the disclosed embodiments, as the professional person for this area easily expects, such change should belong within the scope of the claims in the present invention restriction.
