Description
Technical field
The present invention relates to the electric lighting technical field, particularly a kind of amalgam temperature control device for electrodeless lamp.
Background technology
Electrodeless florescent lamp is based on a kind of new type electro source that the known low pressure gaseous discharge of people and high-frequency electromagnetic induction principle combine.Because it does not have necessary filament of conventional electric light source or electrode, so the name electrodeless florescent lamp is called for short electrodeless lamp.Be a kind of of fluorescent lamp.Electrodeless lamp principle of luminosity is behind the supply voltage of input certain limit, produce high-frequency signal transmission to the coil that is wrapped in toroidal core by the ballast radio-frequency generator, making that magnetic core is inner forms closed induced field, thereby and further goes out the ring electric field excited inert gas and mercury vapour makes the fluorescent tube Discharge illuminating in the fluorescent tube induced inside.Be principle with the electromagnetic coupled promptly, can form the flash-over characteristic of electrodelessization, thereby make the generation of induction non-polar lamp become possibility.Forming plasma discharge by the toroidal inductive field coupled is the basis, excites Hg atom 253.7nm line emission, and then excites three primary colors fluorescent powder to send visible light.
In low-pressure gaseous discharge lamp field, particularly fluorescent lamp, all be added with a certain amount of mercury.Fluorescent lamp is worked by the mercury vapour of certain air pressure of exciting mercury and forming.Because very easy being evaporated to of mercury causes harm in the air, because: 1, evaporated in the time of 0 ℃, temperature is higher, and evaporation is more the more; 10 ℃ of evaporation rates of every increase increase by 1.2～1.5 times approximately, and evaporation is more during air flows.2, mercury is water insoluble, can be evaporated in the air by the water seal layer on surface.3, viscosity is little and mobile big, very easily is broken into little globule, resides in the slit of locating in workbench, ground etc. all-pervasively, and both difficult the removing makes surface area increase again and a large amount of evaporation, forms the secondary pollution source.4, mercury vapour is all adsorbed on the surface of ground, workbench, wall ten ceilings etc., and sometimes, the mercury job shop moves and uses it for anything else, the still residual problem that mercury harm is arranged.Pollution on workman's clothing and the skin can be taken to and cause harm in the family.
So eliminate gradually in field of fluorescent lamps at present and use liquid mercury, and use amalgam, usually amalgam is loaded in the blast pipe of fluorescent tube.Amalgam adopts titanium amalgam, zinc amalgam, indium amalgam (also claiming the indium net), the perhaps mixture of multiple amalgam usually.In the fluorescent tube that uses liquid mercury, the mercury control point that mercury vapour is pressed is to put by the minimum temperature of tube wall to control.And to be position temperature by main amalgam determined at the mercury control point that the fluorescent lamp mercury vapour that uses amalgam is pressed.Amalgam the mercury vapour air pressure when normal temperature used owing to fluorescent lamp is very low, causes the initial brightness of fluorescent tube very low like this, and luminous flux is set up slower.When temperature is lower than zero degree, often need the light that 10 fens clock times or longer time just can reach more than 70% logical.If temperature is lower than in subzero 10 degree or the open type light fixture, all can't reach the logical output of normal light always.
At present, the general method that when using main amalgam, increases Auxiliary amalgam that adopts.The general indium amalgam that adopts is as Auxiliary amalgam.Its effect is that the indium layer absorbs mercury atom when turning off the light, and fluorescent tube opens when jumping the indium layer release mercury atom that is heated, and helps fluorescent tube to open jumping, quickens luminous flux and sets up, and makes fluorescent tube bright sooner.But fusing point is very low, only 156.61 ℃.Fluorescent tube is after operate as normal, and the temperature of fluorescent tube can be than higher, and for example electrodeless lamp will reach more than 120 degree.The wriggling of indium is very strong like this, and long-term lighting can cause the fluorescent tube blackout, and special harm in this long-life lamp tube of electrodeless lamp is particularly evident, and the light decay of fluorescent tube and life-span are significantly shortened, can't the maximum advantage of bringing into play electrodeless lamp.And below subzero 10 degree, even use indium amalgam, the initial brightness of fluorescent tube is still very low, and luminous flux is set up still slower, is difficult to satisfy the requirement of using.When variation of ambient temperature, the temperature of amalgam can change thereupon in addition, and the mercury vapour in the fluorescent tube is changed thereupon, thereby the power of fluorescent tube is also and then changed.The power invariability of fluorescent tube in the time of can't accomplishing variation of ambient temperature, thus luminous flux also can't be constant, influences the luminous efficiency of fluorescent tube.Controlling the temperature of amalgam in the fluorescent tube well, is the problem that prior art need solve.
Summary of the invention
