Description

The electrodeless lamp of a kind of high heat radiation

Technical field

The utility model relates to a kind of lighting, particularly relates to the electrodeless lamp of a kind of high heat radiation.

Background technology

Electrodeless lamp (Promise Light, high-frequency plasma discharge electrodeless lamp) has high light efficiency, high-color rendering, plurality of advantages such as repeated priming is fast, the life-span is long, energy-saving and environmental protection, thereby is used widely.Electrodeless lamp mainly is made up of radio-frequency generator, coupler and bulb three parts, the energising back produces high-frequency current by radio-frequency generator, and the induction coil on coupler generates an electromagnetic field, and is coupled in the lamp in the mode of responding to, make gas avalanche ionization in the bulb, form plasma.The plasma-excited atom gives off ultraviolet ray when returning ground state, the fluorescent material of bulb inner wall is subjected to ultraviolet ray excited generation visible light.

The mobile jib of existing electrodeless lamp coupler and base are made by aluminium bar and aluminium sheet, because of electrodeless lamp can produce big heat in power conversion, it is not enough particularly only depending on aluminium bar to conduct heat in the bulb inner chamber, and after the temperature rising, the light fixture output light flux is reduced and the life of product shortening, thereby the range of application of electrodeless lamp is restricted.

This shows that above-mentioned existing electrodeless lamp obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.How to found a kind of radiating efficiency that improves coupler, when light fixture is used luminous flux output stable, longer service life, the height that is more conducive to the new structure of the energy-saving and environmental protection electrodeless lamp that dispels the heat, real one of the current important subject that belongs to.

The utility model content

The technical problems to be solved in the utility model provides the electrodeless lamp of a kind of high heat radiation, coupler temperature in the lamp chamber is effectively shed, and longer service life was stablized in luminous flux output when light fixture was used, be more conducive to energy-saving and environmental protection, thereby overcome the deficiency of existing electrodeless lamp.

For solving the problems of the technologies described above, the electrodeless lamp of a kind of high heat radiation of the utility model comprises bulb, heat pipe, coupler, heat dissipation base and radio-frequency generator, and wherein: coupler top is provided with magnet ring, and the magnet ring outside is wound with induction coil, and hypomere is hollow body; Coupler is placed in the bulb inner chamber, and the bottom is connected with heat dissipation base; Insert in the hollow body of coupler the heat pipe upper end, and the lower end contacts with heat dissipation base; The lead-out wire of induction coil is connected with the output port of radio-frequency generator, and power input line is connected with the input port of radio-frequency generator.

As a kind of improvement of the present utility model, described heat dissipation base is provided with the fin-shaped radiating ribs.

Described heat dissipation base is provided with groove, and insert in the groove of heat dissipation base the lower end of heat pipe, and contacts with heat dissipation base.

The described groove outside is provided with pressing plate, and by the screw in compression heat pipe.

The lower end of described hollow body is hollow base, and hollow base is connected by screw with heat dissipation base.

Be provided with the anchor point that hasp is complementary that is connected in the described hollow base with bulb.

Described heat dissipation base is aluminium or copper material.

After adopting such design, the lamp chamber intercoupler temperature of the electrodeless lamp of the utility model can effectively shed, and luminous flux output was stablized when light fixture used, and had the advantage of long service life, energy-saving and environmental protection.
