Abstract
The utility model discloses an annular lamp tube of a double cold junction low-frequency electrodeless lamp. The annular lamp tube is sleeved with two coil magnet rings symmetrically, two cold junction tubes are arranged on the lamp tube, one cold junction tube is arranged on one side of each coil magnet ring, and one cold junction tube is filled with solid amalgam and indium net. The cold junction tubes are arranged beside the coil magnet rings to facilitate the heating of solid amalgam; after an electronic ballast generates high-frequency current, a high-frequency magnetic field is generated around the lamp tube by the coil magnet rings, so as to generate a high-frequency vortex electric field and accelerate free electrons in a discharge space, further lead free electrons to collide with mercury vapor atoms generated through acceleration and to generate excitation and ionization, and accelerate the start of the electrodeless lamp; and meanwhile, the arrangement of the cold junction position facilitates the operations of evacuation and inert gas filling during the production process, the processing is convenient, the lamp tube fabrication process is improved, the tube flow and the tube pressure in the tube can be better controlled, and the utility model overall facilitates the improvements on the lighting effect and the service life of the electrodeless lamp.
Description
Technical field
The utility model relates to electrodeless lamp fluorescent tube, relates in particular to the low frequency electrodeless lamp fluorescent tube.
Background technology
Electrodeless lamp is to be made of fluorescent tube that scribbles fluorescent RE powder and wire coil magnet ring, fill mercury atom and inert gas in the fluorescent tube, the high frequency electrical signal that produces by electric ballast makes the wire coil magnet ring produce high frequency magnetic field around glass lamp, thereby generate the high frequency eddy electric field, cause that free electron quickens, these free electrons bump to produce with mercury vapor atoms and excite and ionization, excite back radiation 253.7nm ultraviolet ray in energy level transition, change into visible light behind the fluorescent material of ultraviolet ray by interior surfaces of glass.Because electrodeless lamp does not use filament or electrode in the course of the work, has avoided the export license problem of conventional light source.At present, existing electrodeless lamp fluorescent tube cold junction is provided with form and mainly contains single cold junction and two cold end structure on the market.Single cold end structure no matter at present, still two cold end structure, the setting of all cold junctions is not only bad for the making of fluorescent tube, and on handling, still have some deficits, to processing technology particularly exhaust air technique have relatively high expectations, can not well compress into row control, thereby influence the light efficiency and the useful life of light source pipe stream and pipe in managing.Therefore, address the above problem, have practical significance.
The utility model content
The purpose of this utility model is to provide a kind of pair of cold junction low frequency electrodeless lamp annular lamp tube, and it can improve the fluorescent tube manufacture craft, better Guan Liuyu pipe in managing is compressed into row control, thus the light efficiency and the life-span of improving electrodeless lamp.
The technical solution adopted in the utility model is as follows:
A kind of pair of cold junction low frequency electrodeless lamp annular lamp tube, comprise annular lamp tube, left coil magnet ring, right coil magnet ring, left cold junction pipe, right cold junction pipe, solid-state amalgam and indium net, left coil magnet ring, right coil magnet ring are sleeved on the annular lamp tube symmetrically, left side cold junction pipe, right cold junction Guan Jun are arranged on the annular lamp tube, it is characterized in that: left cold junction pipe is arranged on one side of left coil magnet ring, right cold junction pipe is arranged on one side of right coil magnet ring, solid-state amalgam and indium net are placed in left cold junction pipe or the right cold junction pipe, and the indium net is between solid-state amalgam and annular lamp tube inner chamber.
Further, left cold junction pipe is arranged on the outside of annular lamp tube, and right cold junction pipe is arranged on the inboard of annular lamp tube.
Further, left cold junction pipe is arranged on the inboard of annular lamp tube, and right cold junction pipe is arranged on the outside of annular lamp tube.
Further, the monnolithic case of described annular lamp tube is circle or ellipse or rectangle.
After the utility model adopts said structure, the cold junction pipe is arranged on that the coil magnet ring is other to be helped solid-state amalgam and be heated, after electric ballast produces high-frequency current, the coils magnet ring produces high frequency magnetic field around fluorescent tube, thereby produce the high frequency eddy electric field, cause that the discharge space free electron quickens, further bumping to produce with the mercury vapor atoms that heats generation excites and ionization, makes electrodeless lamp accelerate to start; Simultaneously this cold junction position be provided be beneficial in process of production vacuumize, the filling inert gas, convenient processing improves the fluorescent tube manufacture craft, can compress into row control, the light efficiency and the life-span that help improving electrodeless lamp generally to Guan Liuyu pipe in managing better.
