The utility model has the characteristics of simple structure, low cost, good anti-shock performance, and the like.
Description
Technical field
The utility model relates to discharge lamp, particularly a kind of electrodeless discharge lamp.
Background technology
The patent No. of Granted publication on the 24th is the known this electrodeless discharge lamp of Chinese patent (notification number CN1028579C) of 92100446.X from May nineteen ninety-five.This kind electrodeless discharge lamp comprises: a bulb that seals in the vacuum tight mode, contain mercury and rare gas, and in an end of bulb a cavity arranged in the bulb; A coil is wound on the sleeve of being made by synthetic material in the cavity of bulb; A magnetic core is contained in the sleeve that synthetic material makes; The tubule that liquid is housed, the fuse that tubule places soft magnetic material to make, and stretch out outside the cavity, and a flange is arranged outside cavity; An installation component is connected with sleeve and the bulb that synthetic material is made, and can be fixed on the flange.The complex structure of this kind electrodeless discharge lamp, the assembling difficulty, cost is higher, haves much room for improvement.
Summary of the invention
The purpose of this utility model is that a kind of improved small-sized electrodeless discharge lamp simple in structure, lower-cost will be provided; Another purpose of the present utility model is the small-sized electrodeless discharge lamp that a kind of sound construction will be provided, have antidetonation or shockproof effect.
In order to achieve the above object, the utility model adopts following technical scheme: according to the utility model, small-sized electrodeless discharge lamp comprises: a bulb that seals in the vacuum tight mode, contain mercury and rare gas in the bulb, and a cavity is arranged in an end of bulb; A magnetic core that is arranged in the described cavity; A coil that is arranged in the described cavity; It is characterized in that described coil directly is wound on the described magnetic core, and fix by the chamber wall of fixing glue and described cavity by the power coupling device that described coil and described magnetic core constituted.
Described fixing glue can be a silicon rubber, also can be epoxide-resin glue, can also be other the glue that condenses.
Described magnetic core can be a cylinder shape magnetic core; It also can be the cylinder shape magnetic core of hollow; It can also be the magnetic core of other shape.
In order to reduce the temperature of described magnetic core, a heat dissipation conductor can be set, this heat dissipation conductor and described magnetic core are fixed.
In order to make described bulb when discharging, send fluorescence, on the wall fluorescence coating can be set within it, in order to obtain ultraviolet light, fluorescence coating is not set on the wall within it.
The utlity model has following good effect: in the utility model device, fix by fixing glue and described cavity by the power coupling device that described coil and described magnetic core constituted, bulb and described power coupling device are become one, not only fixing simple, fixed cost is low, and has very strong antidetonation, shockproof effect; In addition, this power coupling device adopts coil directly to be wound on the magnetic core, its assembly seldom, cost is very low, is well suited for using as a kind of low cost, low power lighting source.
