Abstract
Disclosed is an annular lamp tube of a double-cold-end low frequency electrodeless lamp. Two coil magnetic rings are symmetrically sleeved on the annular lamp tube, two cold-end tubes are arranged on the lamp tube and distributed at the upper edge and the lower edge of the same side of an optional coil magnetic ring, solid amalgam and an indium screen are arranged inside one cold-end tube, and the indium screen is located between the solid amalgam and an inner cavity of the lamp tube. The cold-end tubes which are disposed beside the coil magnetic ring are favorable for heating the solid amalgam, and after electronic ballast generates high-frequency current, a high-frequency magnetic field can be generated surrounding the lamp tube via the coil magnetic rings, thereby generating a high-frequency vortex electric field, accelerating free electrons in discharge space to be further imaged with mercury vapor atoms which are generated by heating so as to generate excitation and ionization and accelerating start of the electrodeless lamp. Simultaneously, the cold-end tubes disposed at the positions are favorable for vacuumizing and filling inert gas during a production process, thereby bringing convenience for processing, improving manufacturing process of the lamp tube, controlling current and voltage inside the tube better, and being favorable for increasing luminous efficacy and prolonging service life of the electrodeless lamp totally.
Description
Technical field
The utility model relates to electrodeless lamp annular lamp tube, relates in particular to the electrodeless lamp annular lamp tube of low frequency annular.
Background technology
Electrodeless lamp is to be made of annular lamp tube that scribbles fluorescent RE powder and wire coil magnet ring, fill mercury atom and inert gas in the annular lamp tube, the high frequency electrical signal that produces by electric ballast makes the wire coil magnet ring produce high frequency magnetic field around the glass ring-shaped fluorescent tube, 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 annular lamp 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 annular lamp 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 annular lamp tube manufacture craft, can compress into row control to Guan Liuyu pipe in managing better, 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 fluorescent tube, left coil magnet ring, right coil magnet ring, last cold junction pipe, following cold junction pipe, solid-state amalgam and indium net, left coil magnet ring and right coil magnet ring are sleeved on the fluorescent tube symmetrically, last cold junction pipe and following cold junction pipe are arranged on the fluorescent tube, it is characterized in that: go up the both sides up and down that cold junction pipe and following cold junction pipe are distributed in a side of coil magnet ring, solid-state amalgam and indium net are placed in the same cold junction pipe, and the indium net is between solid-state amalgam and fluorescent tube inner chamber.
Further, last cold junction pipe and following cold junction pipe are distributed in the outside of left coil magnet ring.
Further, last cold junction pipe and following cold junction pipe are distributed in the inboard of left coil magnet ring.
Further, last cold junction pipe and following cold junction pipe are distributed in the outside of right coil magnet ring.
Further, last cold junction pipe and following cold junction pipe are distributed in the inboard of right coil magnet ring.
Further, the monnolithic case of described fluorescent 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 annular lamp 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 annular lamp 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.
