Abstract
The utility model belongs to a component for an electrodeless lamp illumination electric appliance, and especially relates to a coupler for a high frequency electrodeless lamp. According to the coupler for an electrodeless lamp, magnets are fastened on the external surface of a heat conduction pipe via a heat conduction silica gel; a coil is wound on the external surface of each magnet; a high temperature resistance solidification coating is solidified on the surface of the coil; the heat conduction pipe is of a cylindrical structure and is a working medium capillary vacuum heat conduction pipe; and the two or more than two magnets are uniformly sleeved on the external surface of the heat conduction pipe. The coupler for an electrodeless lamp is fine is heat radiation and long in service life, is provided with a constant inductor (magnetic energy load), and can adapt to electrodeless lamps with different shapes.
Description
Technical field
The utility model belongs to electrodeless lamp electric lighting components and parts, refers more particularly to the intercoupler that HF lamp without electrodes is used.
Background technology
Existing electrodeless lamp does not have the filament and the electrode of conventional light source in its bulb, because of its good energy-conservation property and long-life have obtained promotion and application widely.Electrodeless lamp is mainly by the Based Intelligent Control power supply, novel coupling apparatus and in be coated with the fluorescent material of three primary colors bulb three parts form.The groundwork principle is: the high-frequency electromagnetic field energy advances in the bulb with the induction mode coupling; Make the gas avalanche ionization in the bulb form plasma; Spontaneous radiation went out ultraviolet ray when the plasma excited atom was returned ground state, and the interior fluorescent material of bulb receives ultraviolet ray excited and sends visible light.
Present electrodeless lamp is because the structure of power supply, coupler is different, and its performance has different significantly with life-span and function.Existing coupler is because the peripheral suit of metal mandrel surface is wound with the toroidal magnet of circumferential coil, when the coil on the magnet produces the higher eddy current of intensity through meeting behind the electric current on magnet.This eddy current will change into heat and be dispersed on the magnet.Along with the increase of conduction time, make the magnetic energy coil take place to change for how much a large amount of savings heat energy on the magnet to cause the electric parameter of coupler to change, make magnet temperature rise, thereby photoelectric parameter changes and reduced the performance of magnet.When temperature surpassed the Curie temperature of magnet, magnet can be lost magnetic, and electrodeless lamp will quit work.
The utility model content
To the deficiency of prior art, the utility model provides a kind of good heat dissipation effect, the invariable electrodeless lamp coupler of electric parameter.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is: a kind of electrodeless lamp coupler; It is characterized in that; Magnet is fastened on by heat conductive silica gel on the outer surface of heat pipe, and coil is wrapped on the outer surface of magnet, and the surface cure of coil has the high temperature resistant solidified coating of one deck.
Said heat pipe is a working medium capillary vacuum heat-conduction pipe.
Said heat pipe is a cylindrical structural.
Said magnet is two or more, and evenly distributing is enclosed within on the outer surface of heat pipe.
The utlity model has good heat dissipation effect, long service life, can constant inductance (magnetic energy load) and can adapt to the advantage of the use of electrodeless lamp that can not shape.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed description.
A kind of electrodeless lamp coupler, as shown in Figure 1, magnet 1 is fastened on by heat conductive silica gel 5 on the outer surface of heat pipe 4, and coil 3 is wrapped on the outer surface of magnet 1, and the surface cure of coil 3 has the high temperature resistant solidified coating 2 of one deck.Said heat pipe 4 is a working medium capillary vacuum heat-conduction pipe.Said heat pipe 4 is a cylindrical structural.Said magnet 1 is two, and evenly distributing is enclosed within on the outer surface of heat pipe 4.
High-temperaure coating 2 heatproofs in the said structure reach 500-800 ℃, have guaranteed magnetic energy coupled electric parameter stability, good heat dissipation effect.Heat pipe 4 increases heat dissipation capacity with high-temperaure coating 2, uses good heat conduction effect, can the heat transferred that magnet 1 produces be gone out, and has increased the useful life of coupler, also can adapt to the use of the electrodeless lamp of different sizes simultaneously.
