Abstract
The utility model relates to a low frequency electrodeless induction lamp, comprising a high frequency generator, a coupler and a bulb, wherein the coupler comprises an iron oxygen magnetic core arranged on the bulb and an induction coil wound on the iron oxygen magnetic core, the induction coil is connected with the high frequency generator through wires, the bulb is provided with a bulb housing, the bulb is filled with low pressure mercury and inert gases therein, the bulb housing is provided with main amalgam and auxiliary amalgam thereon, the auxiliary amalgam is arranged in one glass tube, the tube cavity of the glass tube is communicated with the bulb housing, the joint of the glass tube and the bulb housing is also provided with an indium net, and between the indium net and the auxiliary amalgam there is provided a porous ceramic body playing a part of separation. The low frequency electrodeless induction lamp has a simple structure; the high temperature resistant porous ceramic body is used to separate the auxiliary amalgam from the indium net, thereby preventing the indium net from being stained by mercury, and preventing the auxiliary amalgam from dropping in the bulb housing; and the glass tube contracts inside the bulb housing, thereby shortening the external length of the auxiliary amalgam and accelerating starting speed.
Description
Technical field
The utility model relates to a kind of low frequency electrodeless sense light.
Background technology
Electrodeless lamp belong to the 4th generation illuminating product; No filament, electrodeless be the abbreviation of electrode-less gas discharge fluorescent lamp, electrodeless lamp is the new high-tech product that the up-to-date scientific and technological achievements in field such as Application Optics, power electronics, plasma, magnetic material are developed out.The characteristics that long-life, high light efficiency, high-color rendering are arranged.Electrodeless lamp is made up of radio-frequency generator, coupler and bulb three parts.It is that electromagnetic field through radio-frequency generator is coupled in the lamp with the mode of induction, makes the gas avalanche ionization in the bulb, forms plasma.The plasma-excited atom gives off ultraviolet ray when returning ground state.The fluorescent material of bulb inner wall receives ultraviolet ray excited generation visible light.Electrodeless lamp is divided into HF lamp without electrodes and low frequency electrodeless lamp, and its principle of luminosity is the same basically, but very big difference is also arranged.The developing direction of electrodeless lamp is lower frequency, the longer life-span.No matter the high frequency low frequency all need detect through electromagnetic interference (EMI) electrodeless lamp product.
Radio-frequency generator is that coupler provides a high-frequency energy to excite and keeps the gas discharge in the bulb; In radio-frequency generator input bulb, it mainly comprises magnetic core and the induction coil on the magnetic core to coupler energy, and induction coil is connected through cable with radio-frequency generator, and the effect of induction coil and magnetic core is the generation high frequency magnetic field; Bulb mainly is a glass bulb, mainly comprises the cell-shell that scribbles diaphragm and three primary colors fluorescent powder, interior pipe, amalgam, Auxiliary amalgam and lamp holder, and inside is filled with low-pressure mercury and inert buffer gas.Two kinds of amalgam are arranged in the electrodeless lamp, and main amalgam is arranged in the short tube of cell-shell bottom, in case the lamp steady operation it mercury atom just is provided.It is online that Auxiliary amalgam is placed on an indium of being close to cavity, and the indium net is contacted with heat discharge, and mercury atom is evaporated from Auxiliary amalgam very soon during energising, and when power-off, the indium net cools off fast, collected most of mercury atom in the bulb, in order to starting next time.Main amalgam is guaranteed the stable light output of maintenance in a wider temperature range, and Auxiliary amalgam guarantees to export fast and stable.Auxiliary amalgam is often fallen into the cell-shell internal influence and is normally used in the prior art, and toggle speed waits not enough slowly.
The utility model content
The technical problem that the utility model will solve is: in order to solve the deficiency of prior art, the utility model provides a kind of low frequency electrodeless sense light, separates Auxiliary amalgam and indium net, prevents that the indium net is stained with mercury, prevents that Auxiliary amalgam from calling in the cell-shell.
The utility model solves the technical scheme that its technical problem adopted: a kind of low frequency electrodeless sense light, comprise radio-frequency generator, coupler and bulb, and coupler comprises the iron oxygen magnetic core that is arranged on the bulb and the induction coil on the iron oxygen magnetic core; Induction coil is connected through lead with radio-frequency generator; Bulb has cell-shell, is filled with low-pressure mercury and inert gas in the cell-shell, has main amalgam and Auxiliary amalgam on the cell-shell; Described Auxiliary amalgam is positioned in the glass tube; The tube chamber of described glass tube is communicated with cell-shell, and glass tube and cell-shell junction also are provided with the indium net, also is provided with dividing porous ceramic bodies between indium net and the Auxiliary amalgam.
As preferably, described porous ceramic bodies is cylindrical, and glass tube is cylindrical, and the face of cylinder of porous ceramic bodies is connected with the contact of the inwall of glass tube.
For improving the toggle speed of electrodeless lamp, described glass tube and cell-shell junction are recessed in the cell-shell housing.
As preferably, described glass tube and cell-shell junction are recessed in cell-shell housing 3-5mm.
The beneficial effect of the utility model is; The low frequency electrodeless sense light of the utility model is simple in structure, separates Auxiliary amalgam and indium net with high temperature resistant porous ceramic bodies, prevents that the indium net is stained with mercury; Prevent that Auxiliary amalgam from falling into cell-shell; It is inner with cell-shell to contract in the glass tube, to shorten the outer length of Auxiliary amalgam, accelerates toggle speed.
