Description
Technical field
The utility model relates to a kind of electrodeless lamp dedicated lamp, belongs to lighting technical field.
Background technology
Electrodeless lamp has multiple advantages such as energy-conservation, life-span length, environmental protection than conventional bulb, has obtained the promotion and application of wide model in recent years.Electrodeless lamp is made up of three parts: frequency generator, power coupler and scribble the bulb of rare-earth trichromatic fluorescent powder.The groundwork principle of electrodeless lamp is: the energy of electromagnetic field of certain frequency is coupled in the bulb with induction mode, make inert gas (mist of krypton gas and the argon gas) avalanche ionization in the bulb form plasma, spontaneous radiation went out the ultraviolet ray of 254nm when the plasma excited atom was returned ground state, and bulb inner wall fluorescent material is subjected to sending visible light after ultraviolet ray excited.Power coupler wherein is made up of metal mandrel, magnet, coil again, will produce very high eddy current when feed electric current on magnet after.The energy consumption of this eddy current will change into joule Lenz's heat and be released on the magnet, and along with the lengthening of conduction time, the temperature on the magnet can sharply rise, and then reduce energy of electromagnetic field and reduce fluorescence volume, and promptly operating efficiency reduces.Especially when temperature surpassed the Curie temperature of magnet, magnet can be lost magnetic and electrodeless lamp can't be worked.
Existing electrodeless lamp is to conduct heat to the heat radiation of electrodeless lamp end by the metal mandrel in the power coupler (copper rod or aluminium bar are arranged), according to investigations, be contained in the same side at transitional street lamps light fixture medium frequency generator and power coupler, can interfere with each other, and to only depend on end heat radiation be not enough, can seriously influence the luminous efficiency of electrodeless lamp, shorten its useful life, particularly the light fixture inner chamber degree of protection of top grade to reach IP65 be difficult to more heat is distributed.
The power coupler of electrodeless lamp, electrodeless lamp bulb and electrodeless modulation frequency generator three parts all are heaters, the heat of any part looses not go out all can influence the life-span of electrodeless lamp and luminous efficiency, and the temperature of especially electrodeless modulation frequency generator electronic devices and components can not be too high.So three thermals source will be contained in different positions, separate after shell outwards conducts heat, these three heaters can not conducted mutually and radiations heat energy, this is the key that improves light efficiency, guarantees electrodeless lamp operate as normal.
Summary of the invention
The purpose of this utility model provides a kind of electrodeless lamp dedicated lamp of good heat dissipation effect.
The technical scheme that realizes above-mentioned purpose is: a kind of electrodeless lamp dedicated lamp, comprise electrodeless lamp bulb, electrodeless lamp radiator, power coupler, frequency generator and hinged loam cake and lower cover, the bottom of lower cover is equipped with glass, electrodeless lamp bulb, electrodeless lamp radiator, power coupler and frequency generator are installed in the lower cover, power coupler is positioned at the front end of lower cover, and frequency generator is positioned at the rear end of lower cover; The lower cover front end is shaped on preceding fin, and power coupler is connected with this front end fin by electrodeless lamp radiator, and following cover back-end is equipped with the back fin that is connected with frequency generator, separates with thermal insulation board between power coupler and frequency generator; On cover and be fixed with and the corresponding reflection shield of electrodeless lamp bulb, and between reflection shield and loam cake, be lined with heat-conducting block.
The further technical scheme of the utility model is: the junction of glass and lower cover has rubber weather strip.The junction of loam cake and lower cover has rubber weather strip.
Further, between electrodeless lamp bulb and the frequency generator thermal insulation board is installed, and thermal insulation board is located in the lower cover.
After adopting technique scheme, whole lamp housing loam cake is as the radiator of electrodeless lamp bulb, the lower cover front end is as the electrodeless lamp power couplers radiator, following cover back-end is as the radiator of electrodeless modulation frequency generator, power coupler conducts and distribute heat by electrodeless lamp radiator and light fixture lower cover front end fin, frequency generator conducts and distribute heat by cover back-end fin under the light fixture, and heat can effectively distribute by lower cover; Fixedly thermal insulation board can separate the power coupling of golf calorific value and electrodeless lamp bulb and frequency generator at the middle part; The centre that is connected at loam cake and reflection shield is lined with the reflection shield heat-conducting block, increased the contact area of reflector and loam cake, thereby the heat that effectively electrodeless lamp bulb is distributed is transmitted to reflection shield, through the reflection shield heat-conducting block heat is distributed by the light fixture loam cake.By this multizone, multipath heat conduction, can produce the electrodeless lamp power couplers of heat, electrodeless modulation frequency generator, electrodeless lamp bulb with three and separate mutually, both prevented by three regional heat conduction that thermal source from conducting mutually, outwards conduct heat from the zone of three separations by shell again, thereby guarantee the working temperature that electrodeless lamp is stable effectively.
By adopting further technical scheme, guarantee between glass and the lower cover, the sealing property between loam cake and the lower cover, make the sealing grade of electrodeless lamp dedicated lamp can reach IP65, thereby guaranteed that electrodeless lamp can normally stably work, prolonged the useful life of electrodeless lamp bulb.
By between electrodeless lamp bulb and frequency generator, thermal insulation board being installed, the power coupler of golf calorific value and electrodeless lamp bulb and frequency generator can be separated, can prevent that thermal source from conducting mutually.
