The electrodeless lamp of tandem compound electroluminescent
Technical field
The utility model relates to a kind of lighting, the electrodeless lamp of a kind of specifically tandem compound electroluminescent.
Background technology
No filament in the lamp body of electrodeless lamp, electrodeless, the no any and outside introducing electric wire that is connected is a kind of energy-efficient, the new type light source that the life-span is long.The electrodeless lamp of electroluminescent adopts high frequency crossed electric and magnetic field field to cause gas discharge principle, makes bulb luminous, rather than electromagnetic induction luminescent.Like the patent No. is the patent of ZL200920012819.4; Comprise bulb, electromagnetic field generator, power supply and lamp holder; Constitute the electrodeless lamp of compact integral type; Described electromagnetic field generator places space in the bulb stern column, and the wire tripper of its inductance coil is connected on the lamp holder through power supply, in bulb, is filled with mist.The utility model adopts high frequency crossed electric and magnetic field field to cause gas discharge principle, makes bulb luminous.The common specification of this electrodeless lamp is less, and heat dispersion is limited, can't realize high-power light-emitting.
The utility model content
To above-mentioned weak point of the prior art, the technical problem that the utility model will solve provides a kind of electrodeless lamp of tandem compound electroluminescent more high-power and that dispel the heat good of realizing.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is: the electrodeless lamp of a kind of tandem compound electroluminescent; Connect coupler on the lamp socket, coupler is with lamp body outward, and said lamp body is inside and outside double-layer glass tube; Form an enclosure space; Enclosure space is filled with discharge gas, constitutes a gas discharge lamp body, and the glass outer pipe internal surface scribbles fluorescent material; The heat pipe of said coupler is surrounded by many group magnets outward, and every group of magnet is by separated magnetic orientation case off, and every group of magnet is wound with coil respectively, and each is organized the coil differential concatenation and is supplied power by radio-frequency generator, and two adjacent groups magnet poles direction NN or SS are relative.
The heat pipe of said coupler is hollow and the metal tube that is filled with the thermal diffusion solvent.
The heat pipe of said coupler is the air-cooled one radiator of connecting band fan also.
Said air-cooled one radiator carries out power source conversion through radio-frequency generator.
The central point of the fan of said air-cooled one radiator is positioned on the center line of electrodeless lamp, perpendicular to coupler.
Said magnet is made up of the outer coiling of the low permeability metal tube of sealing.
The utlity model has following advantage:
1. through the electric field excitation gas luminescence, the direct conversion times of photoelectricity is few, and efficient is high;
2. do not have filament, electrodeless, photoelectric cell is lossless, the life-span is high;
3. combined structure can be made the electrodeless lamp of big specification.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed description.
Embodiment 1:
As shown in Figure 1, the electrodeless lamp of tandem compound electroluminescent comprises connecting coupler 2 on the lamp socket 3; Coupler 2 outsides are with lamp body 1, and lamp body 1 is inside and outside double-layer glass tube, have formed an enclosure space between the layer glass pipe; This enclosure space is filled with discharge gas; Therefore, lamp body 1 becomes a gas discharge lamp body, and the glass outer pipe internal surface scribbles one deck three primary colors fluorescent powder.
As shown in Figure 2, the heat pipe outside of coupler 2 is surrounded by many group magnets 4, separates with separated magnetic orientation sleeve pipe 5 between every group of magnet; Every group of magnet is wound with coil respectively, and each is organized the coil differential concatenation and is supplied power by radio-frequency generator, and the coil winding direction of two adjacent magnets is opposite; For example, the coil winding direction of one group of magnet is left-handed, and the winding direction of two groups of magnet coils that this magnet is adjacent so just is dextrorotation; By that analogy, make two adjacent groups magnet 4 pole orientation NN or SS relative.The coil of the magnet of least significant end is reserved two coil interfaces, is used for connecting the positive and negative end of radio-frequency generator 7.
In addition, heat pipe is connected with the air-cooled one radiator 6 of band fan, and air-cooled one radiator 6 carries out power source conversion through radio-frequency generator 7, and the central point of the fan of air-cooled one radiator 6 is positioned on the center line of electrodeless lamp, perpendicular to coupler 2.The heat pipe of coupler 2 can obtain good performance of heat dissipation with the acting in conjunction of air-cooled one radiator 6 in addition of its quick conductive performance.
As shown in Figure 3, the heat pipe 9 of coupler 2 is a hollow, and is filled with the metal tube of thermal diffusion solvent 8, and this metal tube is selected the low permeability metal tube for use, for example, can select the metal tube of non-iron.
After the electrodeless lamp energising, radio-frequency generator 7 converts the line voltage that the outside supplied to fan operate as normal that low pressure supplies magnet coil and air-cooled one radiator 6 rapidly, and radio-frequency generator 7 can provide the characteristic power supply of 13.56MHZ for whole lamp system.After radio-frequency generator 7 power supplies, organize magnet 4 more and generate an electromagnetic field, excite discharge gas discharge in the lamp body 1, produce the 253.7nm ultraviolet radiation in the discharge, the ultraviolet ray excited fluorescent material that is coated in envelope surfaces sends visible light.
Embodiment 2:
As shown in Figure 4, be that with embodiment 1 difference the other end of lamp body 1 also is connected to lamp socket 3, when lamp body 1 is long, can use this lamp socket to fix, be beneficial to installation.
