Background technology
Brief overview is the history of illuminating lamp once, and new light sources such as incandescent lamp, tungsten halogen lamp, fluorescent lamp, high-pressure mercury lamp, Metal halogen lamp, fluorescent lamp emerge in an endless stream, and with regard to principle, incandescent lamp, tungsten halogen lamp belong to heat radiation light source, and it is arc discharge lamp that the latter belongs to.But no matter be that a kind of light source, a similarity is all arranged, that just has been to use filament or electrode, and this limits the central factor of light source life just.The light source of every kind of existence all has its unique distinction, but also shows the defective of self simultaneously, promptly can not take into account simultaneously aspect environmental protection and the energy-conservation quality of lighting such as height such as grade.All gaseous discharge lamp great majority can not start and restart immediately, have shortcomings such as power factor is low.In addition, these light sources have also brought very important light pollution to the mankind, i.e. dazzle, ultra-violet radiation and stroboscopic effect etc.
Popular in the market all is high-power, split type HF lamp without electrodes, does not match owing to the power height and with traditional lamp holder, so can not substitute electricity-saving lamp commonly used.
Summary of the invention
To above-mentioned prior art, the utility model provides a kind of integrated high-frequency electrodeless lamp, and it can be adaptable across places such as family, office building, dining room, hotel, museum, market, classroom's illuminations.
The utility model is realized through following technical scheme:
Integrated high-frequency electrodeless lamp comprises double glazing foam, power coupler, high frequency ballast and lamp holder, wherein; High frequency ballast is positioned in the lamp holder; The double glazing foam is connected with lamp holder, and power coupler is positioned in the cavity between double glazing foam and the lamp holder, is filled with argon gas in the double glazing foam; Double glazing foam inside bottom is provided with amalgam, is coated with three primary colors fluorescent powder on the double glazing foam inwall; Said power coupler is made up of high copper rod of magnetic core, coil, conductive coefficient and the high aluminium radiator fin of coefficient of heat transfer; Magnetic core is enclosed within copper rod one end; Coil is wrapped on the magnetic core, and coil is connected with the high frequency ballast circuit, and aluminium radiator fin is connected the copper rod other end.
Said magnetic core is annular ferrite.
Said lamp holder is E27 common in the prior art or slightly larger E40 lamp holder.
Said coil is that resistant to elevated temperatures lead is entwined (coil is a coil conventional used in the prior art, and the utility model does not have improvement to this).
Said high frequency ballast is the core component of the integrated high-frequency electrodeless lamp of the utility model, and its parameter changes the working condition that directly influences the double glazing foam.In the prior art; The high frequency ballast that HF lamp without electrodes adopts is of a great variety; But its central principle all is identical: promptly utilize switching circuit to realize low frequency AC arrives high-frequency AC again to DC conversion; Usually form by five parts, i.e. EMI filter circuit, rectification circuit, circuit of power factor correction, inverter circuit and protective circuit.The high frequency ballast that the utility model adopted repeats no more at this with of the prior art identical.
Operation principle is: during work, high frequency ballast is connected with the civil power of alternating current 220V through lamp holder, and the high-frequency alternating current that high frequency ballast produces puts on the coil of power coupler; Electric current through coil produces alternating flux in the magnetic core of annular; In the closed space of double glazing foam, form the high frequency alternating electric field, make the amalgam evaporation, form argon-mercury plasma and discharge with argon gas; Form ultraviolet ray output, thereby excite the three primary colors fluorescent powder of double glazing foam inwall luminous.
The beneficial effect of the utility model has:
1, light efficiency is high: adopt the principle of high-frequency discharge, very high light efficiency can be arranged.
2, the life-span is long: the integrated high-frequency electrodeless lamp of the utility model does not have electrode; Adopt the high copper rod of conductive coefficient, the aluminium bar that coefficient of heat transfer is high; Complete protective circuit is like overvoltage, overcurrent, short circuit etc.; The device of imported with original packaging so the life-span is very long, can reach more than 60000 hours usually, has reduced maintain and replace, is particularly suitable for the illumination place of maintenance difficult.
3, light decay is little: because there is not electrode, discharging condition changes little, so can not influence the luminous flux of lamp owing to export license.
4, convenient repacking: the integrated high-frequency electrodeless lamp of the utility model, E27 or E40 lamp holder are housed, be suitable for illumination places such as family, office building, classroom, can directly substitute primary lights such as electricity-saving lamp, convenient repacking.
5, high power factor: the integrated high-frequency electrodeless lamp of the utility model adopts circuit of power factor correction (PFC), and its power factor can reach more than 0.95, has improved conversion efficiency, significantly reduces the pollution of light source to electrical network simultaneously.
6, mercury pollution is low: what use in the integrated high-frequency electrodeless lamp of the utility model is amalgam, rather than directly charges into liquid mercury, has controlled mercury pollution so in process of production; And its long working life, the mercury consumption of practical application is significantly reduced than other light source, thereby reduced the pollution of mercury effectively, really accomplished environmental protection.
7, illumination good visual effect: the integrated high-frequency electrodeless lamp operating frequency of the utility model is about 2.65MHZ, is higher than other light source works frequency far away, therefore has no scintillation, and human eye perceives is comfortable, can effectively protect people's eyes.
8, good looking appearance: the integrated high-frequency electrodeless lamp volume of the utility model is little, and the duty area is little, and is small and exquisite attractive in appearance.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Integrated high-frequency electrodeless lamp comprises double glazing foam 1, power coupler, high frequency ballast 6 and lamp holder 7 (E27 lamp holder), and is as shown in Figure 1; Wherein, High frequency ballast 6 is positioned in the lamp holder 7, and double glazing foam 1 is connected with lamp holder 7, and power coupler is positioned in the cavity between double glazing foam 1 and the lamp holder 7; Be filled with argon gas in the double glazing foam 1; Double glazing foam 1 inside bottom is provided with amalgam 4 (amalgam 4 is liquid amalgam, is the particle that mercury element forms), is coated with three primary colors fluorescent powder on double glazing foam 1 inwall; Said power coupler is made up of high copper rod 3 of the ferritic magnetic core of annular 8, coil 2, conductive coefficient and the high aluminium radiator fin 5 of coefficient of heat transfer; Magnetic core 8 is enclosed within copper rod 3 one ends; Coil 2 is wrapped on the magnetic core 8; Coil 2 is connected with high frequency ballast 6 circuit, and aluminium radiator fin 5 is connected copper rod 3 other ends.
