Compared with the prior art, the improved structure of the promise light can dissipate heat generated inside the promise light effectively and enable luminous output of the promise light to be stable, thereby being long in service life and more favorable for energy conservation and environment protection so as to overcome shortcomings of the existing promise light.

Description

A kind of electrodeless lamp improves structure

Technical field

The utility model relates to lighting field, is specifically related to a kind of electrodeless lamp and improves structure.

Background technology

Electrodeless lamp belong to the 4th generation illuminating product, no filament, electrodeless; Being the discharge abbreviation of electrodeless lamp of Promise Light high-frequency plasma, is integrated application optics, power electronics, plasma is learned and the up-to-date scientific and technological achievement in fields such as magnetic material is developed out new high-tech product, is a kind of new type light source of representing the high light efficiency of lighting engineering, long-life and high-color rendering future thrust; Electrodeless lamp comprises radio-frequency generator, coupler and bulb etc.; They are different with conventional fluorescent lamps, and the electromagnetic field that concrete operation principle is a radio-frequency generator is coupled in the lamp with the mode of induction, according to Faraday's electromagnetic induction law; The magnetic field that changes can produce induced-current in fluorescent tube; But thereby make the discharging substance generation discharge effect that is carried in the fluorescent tube, make the gas ionization in the bulb, form plasma; The excited atom of plasma gives off ultraviolet ray when returning ground state; The fluorescent material of bulb inner wall receives the ultraviolet generation visible light that excites, and compares with conventional light source such as electricity-saving lamp, Metal halogen lamp and high-pressure mercury lamps, has significant superiority; Be specially adapted to change the place of lamp difficulty and expensive and the important place higher, like tunnel, traffic complex area, subway station, factory building, the illumination of dangerous region, hall and sports ground etc. that ceiling is very high to safety requirements.

Because electrodeless lamp does not have electrode, there is not fallible component in the fluorescent tube part, and the life-span of whole system depends primarily on radio-frequency generator; So if can guarantee the quality of radio-frequency generator, the life-span of this type lamp will be very long, can reach more than 60,000 hours; But because the unique principle of luminosity of electrodeless lamp is compared with conventional lights, electrodeless lamp will send the light of same intensity; Just certainly lead to more heat, these heats must in time distribute in bulb, otherwise after being accumulated in the electrodeless lamp; Heating up gradually in inside, can't work in magnetic field, and then cause the electrodeless lamp can not be normally luminous and its inner components and parts of damage; To having occurred some improved structures on the above situation market, as adopting heat-transfer device and/or lead heat is derived, though can play certain effect; But its complex structure and cost are high, are unfavorable for enlarging producing, so be necessary to find a kind of practicable means that can the simple and effective way that the heat in the electrodeless lamp is derived be only the electrodeless lamp behaviour of performance.

The utility model content

The purpose of the utility model is to provide a kind of simple and reasonable electrodeless lamp to improve structure, has and can the heat that produce in the electrodeless lamp be shed effectively, makes the luminous flux output of electrodeless lamp stable, and prolong and low cost and other advantages service life.

In order to achieve the above object, the technical scheme of the utility model is:

A kind of electrodeless lamp improves structure, comprises bulb, coupler, the lamp holder that links to each other with bulb and is connected in the base at lamp holder place, and said coupler has magnetic core, and the respective ends of said magnetic core and said lamp holder connect; Above-mentioned base is the mount pad that metallic aluminum material is processed.

Above-mentioned base is provided with heat abstractor.

Above-mentioned heat abstractor is a fin of being located at the outer surface of above-mentioned base.

After adopting technique scheme, the electrodeless lamp of the utility model improves structure, compared with prior art; The mount pad that base adopts metallic aluminum material to process because the heat conductivility of metallic aluminium is strong, can further improve the effect of base to the heat radiation of electrodeless lamp; And it has light weight and lower-cost advantage to compare other metals, and the inner heat of electrodeless lamp is derived and be dispersed into the outside of electrodeless lamp again by the base that connects with magnetic core after the magnetic core conduction of coupler, with this heat that produces in electrodeless lamp is shed effectively; Make the luminous flux output of electrodeless lamp stable; Prolong service life, be more conducive to energy-conservation and environmental protection etc., thereby overcome the deficiency of existing electrodeless lamp; Further, base is provided with heat abstractor, can further strengthen the radiating effect of base.

The specific embodiment

In order further to explain the technical scheme of the utility model, set forth in detail through specific embodiment below.

A kind of electrodeless lamp of the utility model improves structure, shown in Fig. 1-2, comprises bulb 1, coupler 2 and the lamp holder 3 that links to each other with bulb 1, also comprises base 4.

Coupler 2 has magnetic core 21; The electrodeless lamp of the utility model improves structure and effectively utilizes existing structure, on the basis of conventional bulb 1, coupler 2 and lamp holder 3, adopts metallic aluminium to make the base 4 of electrodeless lamp; At first magnetic core 21 is at inner straight to the lamp holder 3 of bulb 1 and carry out good heat conduction with lamp holder 3 and be connected; Again lamp holder 3 directly is connected with base 4, makes base 4 and lamp holder 3 can carry out good heat transmission, behind the heat that magnetic core 21 is concentrated in the electrodeless lamp; Lamp holder 3 can be with the heat transferred base 4 on the magnetic core 21; Base 4 exports to this heat outside the electrodeless lamp again, fin 41 further is set as heat abstractor on base 4, can improve the heat dispersion of base 4.

The electrodeless lamp of the utility model improves structure, and is in use, identical with the electrodeless lamp of tradition; Inside will produce great amount of heat; Magnetic core will absorb and concentrate this heat, and the warp smoothly that has no to be interrupted and magnetic core carry out lamp holder that heat conduction is connected and pass to lamp holder and carry out the outside that metal aluminum base that heat conduction is connected exports to electrodeless lamp again, and fin can increase the area of dissipation of base; Radiating effect is stronger, guarantees that with this each light-emitting device continues operate as normal and prolongs its service life in electrodeless lamp.

The electrodeless lamp of the utility model improves structure, and the heat conduction ways of connecting of base and lamp holder and lamp holder and magnetic core is not unique, but all can like the connected mode of existing heat conduction such as welding, tight fit or buckle; The shape and size of base can require to design and adjust to produce according to reality; Magnetic core also can directly carry out heat conduction with base and be connected, and passes lamp holder and base heat conduction links together like magnetic core; For make things convenient for magnetic core and lamp holder or directly with base be connected the shape or the size of adjustment magnetic core that can be suitable; The form of fin is not unique, and like all or part of sheet or the annular form that is laid on the base, and heat abstractor also can adopt other existing heat radiation forms, like radiator fan etc.

The product form of the utility model and the scope of application are not limited to this case diagram and embodiment, and any unit or individual are the suitable variation or the modification of the similar thinking of production or business purpose to it, all will be regarded as the enforcement to the patent of the utility model.
