Abstract
The invention provides a high-frequency electrodeless lamp, comprising a high-frequency electronic generator (1), a glass blister (3) and a power coupler (2) which is arranged in the inner chamber of the glass blister (3); fluid body is filled in the power coupler (2); one end of the fluid is contacted with a heat dissipation device (4); the heat quantity generated when the power coupler (2) works is transferred to the heat dissipation device (4) via the fluid body filled in the power coupler and the heat dissipation device releases heat quantity to the outside world, ensuring that the power coupler works in a reliable temperature range. The technique adopted in the invention reduces power consumption, lowers cost, improves heat dissipation efficiency, prolongs service life and can manufacture high-power high-frequency electrodeless lamps.
Description
Technical field
The present invention relates to the electrical lighting light fixture, relate in particular to a kind of energy-saving electronic illuminating lamp tool.
Background technology
HF lamp without electrodes is a kind of new type light source of representing the high light efficiency of lighting technology, longevity, high-color rendering future thrust.High frequency plasma electrodless discharge be the sub-technology of current collection, photoelectric technology, vacuum technique in the high-tech lighting source product of new generation of one, mainly form by radio-frequency generator, power coupler and glass cell-shell three parts.
Main feature: electrodeless in the lamp, the life-span with overlength.Good energy-conserving effect.The luminous efficiency height.Flicker free helps vision health.Start and restart superior performance, can instantaneously light.High-color rendering can be applicable to all kinds of places.The reliability requirement that is particluarly suitable for throwing light on is higher, needs long-term illumination and the place of keeping in repair, change the light fixture difficulty is used.
From number of patent application 91102205.8,96240221.4,200520120335.3 the description of disclosed electrodeless lamp is as can be seen since electrodeless lamp is born, heat dissipation problem just is accompanied by it always, HF lamp without electrodes is along with power is increasing, prior art exists heat dissipation problem more and more outstanding, and a large amount of heats that power coupler produces can not in time distribute, and causes the magnetic core temperature to surpass Curie point and loses efficacy.At present typical technical scheme is that coupler magnetic core and higher temperature line produce high frequency magnetic field, and the unnecessary heat energy that coil produces is transmitted to the aluminum base outside by the copper heat conductive rod or the heat pipe of centre.Base has two kinds of functions: the one, guarantee being connected of bulb and coupler; The 2nd, unnecessary heat is passed to fin or light fixture.Such structure contact heat resistance is big, and the space is narrow and small, and heat flux is little, complex structure, and the power of doing maximumly in the market bubble shape 185W, annular 210W, thus limited the application of HF lamp without electrodes.
Summary of the invention
The technical problem to be solved in the present invention is the radiator structure of the existing electrodeless lamp of high-frequency high-power of improvement, allows the HF lamp without electrodes coupler be operated under the good temperature environment, improves power and efficient.
The present invention solves the technical scheme that the heat radiation of the electrodeless lamp of high-frequency high-power adopts, and manufactures and designs a kind of HF lamp without electrodes, comprising: high-frequency electronic generator, power coupler and electrodless discharge bulb; Described power coupler places electrodless discharge bulb inner chamber, and its induction coil is connected with the high-frequency electronic generator; Drum stand sleeve and heat abstractor form the cavity of a sealing, fill heat-transfer fluid in the cavity.Key technology of the present invention is: adopt the convective heat transfer mode, the coupler magnetic core is immersed in the heat-transfer fluid, the heat that produces during coupler work is absorbed rapidly by fluid, convection current is delivered to the heat abstractor of the other end in cavity, and by heat abstractor to extraneous distribute heat, guarantee that the coupler magnetic core is operated under the good temperature environment.
Described drum stand bush material is made for the insulation and thermal insulation material, and the coupler magnetic core is immersed in the fluid of filling in the cavity of drum stand sleeve and heat abstractor formation.
Described heat abstractor can be passive heat radiation, also can be the active heat removal mode.Construction for heat radiating device can also have a lot, can use as long as play the structure of thermolysis, and this paper does not enumerate one by one at this, is exactly these structures but can not therefore understand heat abstractor of the present invention.
Described fluid can be an organic liquid, inorganic liquid, and solid-liquid mixes body, flowable metal liquid or the like.
With prior art relatively, HF lamp without electrodes of the present invention has following advantage: owing to adopt convective heat transfer, the thermal transmission coefficient height, heat flux is big, and fluid does not have the gap with coupler magnetic core and heat abstractor and contacts, and the heat that power coupler produces at work exchanges with environment rapidly, thereby improved radiating efficiency greatly, make power coupler always work in good temperature environment, improved the power output of HF lamp without electrodes, can easily produce the above high-power high-frequency electrodeless lamp of 200W.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the vertical section structural map of first embodiment of HF lamp without electrodes of the present invention.
Fig. 2 is the vertical section structural map of second embodiment of HF lamp without electrodes of the present invention.
1. high-frequency electronic generators among the figure, 2. power coupler, 3. glass cell-shell, 4. heat abstractor, 5. drum stand sleeve, 6. induction coil, 7. magnetic core, 8. fluid.
Embodiment
In Fig. 1 Fig. 2, high-frequency electronic generator (1) self-maintained circuit switch produces high-frequency signal output and is loaded into induction coil generation high frequency magnetic field by the radioshielding line, excites the gas ionization in the glass cell-shell (3), causes fluorescent material to send visible light.Because power coupler (2) is when glass cell-shell (3) inner chamber is worked, induction coil (6) and magnetic core (7) have produced a large amount of heats, because magnetic core (7) is to be immersed in the fluid (8), induction coil (6) and magnetic core (7) have produced the direct heating fluid of a large amount of heats (8), convective heat transfer mode by fluid passes to heat abstractor (4) rapidly to outside distribute heat, the temperature that guarantees induction coil (6) and magnetic core (7) can be not too high, fluid does not have the gap with coupler magnetic core and heat abstractor and contacts, the heat that power coupler produces at work exchanges with environment rapidly, thereby improved radiating efficiency greatly, make power coupler always work in good temperature environment, improve the power output of HF lamp without electrodes, can easily produce the above high-power high-frequency electrodeless lamp of 200W.
