Abstract
The utility model discloses an electromagnetic induction electroless lamp which comprises an annular closed strip lamp (1) with a uniform pipe diameter, wherein the internal surface of the annular closed strip lamp (1) is provided with a fluorescent coating (2), and a filling substance (3) which can be ionized is filled into an internal cavity of the annular closed strip lamp (1); a ring type magnetic core (4) with a coil (5) is encircled at the external surface of the annular closed strip lamp (1), and a ballast (7) is connected with the coil (5) by a conducting wire (6). The electromagnetic induction electroless lamp has the characteristics of high electromagnetic conversion efficiency and good luminous efficacy.
Description
Technical field
The utility model relates to a kind of electromagnetic induction electrodeless lamp.
Background technology
Electromagnetic induction electrodeless lamp is that the basic principle that relies on electromagnetic induction to form the plasma gas discharge realizes luminous; Owing to do not have filament and an electrode, therefore be 100 times of incandescent lamp the useful life of electrodeless lamp, so electromagnetic induction electrodeless lamp more and more is subjected to liking of people.
Electromagnetic induction electrodeless lamp is made up of ring type magnetic core of the closed fluorescent tube of annular, ballast, belt coil etc., at the inner surface of the closed fluorescent tube of annular fluoresent coating is set, and is filled with ionogenic filling material in the inner chamber of the closed fluorescent tube of annular.The annular closed fluorescent tube of present existing electromagnetic induction electrodeless lamp is to be assembled by 2 semi-circular fluorescent tubes, the end diameter of semi-circular fluorescent tube is less than the diameter of this semi-circular fluorescent tube, therefore when 2 semi-circular fluorescent tube butt joints form the closed fluorescent tube of annular, will make and form 2 grooves on the annular closed fluorescent tube, at 2 grooves the ring type magnetic core of a belt coil is set respectively, promptly ring type magnetic core is around the outside of groove.This ring type magnetic core is the ring type magnetic core that has fracture, rather than the closed loop magnetic core.Therefore the electrodeless lantern festival of said structure impacts magnetic flux, thereby has reduced the electromagnetic conversion efficient of this electrodeless lamp, causes the light transmittance efficiency of this electrodeless lamp relatively poor.
The utility model content
The technical problems to be solved in the utility model provides a kind of electromagnetic conversion efficient height, electromagnetic induction electrodeless lamp that light transmittance efficiency is good.
In order to solve the problems of the technologies described above, the utility model provides a kind of electromagnetic induction electrodeless lamp, the annular closed fluorescent tube that comprises uniform diameter is provided with fluoresent coating at the inner surface of the closed fluorescent tube of annular, is filled with ionogenic filling material in the inner chamber of the closed fluorescent tube of annular; The ring type magnetic core that has coil is looped around the outer surface of annular closed fluorescent tube, and ballast links to each other with coil by lead.
Improvement as electromagnetic induction electrodeless lamp of the present utility model: ionogenic filling material is the charges that amalgam and inert gas are formed.
Further improvement as electromagnetic induction electrodeless lamp of the present utility model: ring type magnetic core is the closed loop magnetic core.
Further improvement as electromagnetic induction electrodeless lamp of the present utility model: the outer surface at ring type magnetic core is provided with anchor ear.
Further improvement as electromagnetic induction electrodeless lamp of the present utility model: annular closed fluorescent tube is annular, square annular or oval ring.
Further improvement as electromagnetic induction electrodeless lamp of the present utility model: the cross section of annular closed fluorescent tube is annular or oval ring.
Further improvement as electromagnetic induction electrodeless lamp of the present utility model: ballast is that frequency is the ballast of 50KHz to 3MHz.
Electromagnetic induction electrodeless lamp of the present utility model, the closed fluorescent tube of annular can be the annular closed fluorescent tube on a plane, also can be an annular closed fluorescent tube (being that the closed fluorescent tube of full annular is not in same plane) with three-dimensional shape. ring type magnetic core is made by high permeability, low-loss Ferrite Material, preferred MnZn ferrite material or nickel-zinc-ferrite material.
Electromagnetic induction electrodeless lamp of the present utility model, because ring type magnetic core is selected the closed loop magnetic core for use, and this ring type magnetic core is looped around the outer surface of the annular closed fluorescent tube of uniform diameter; Therefore can effectively improve magnetic flux, thereby improve the light transmittance efficiency of electromagnetic induction electrodeless lamp.Electromagnetic induction electrodeless lamp contour structures compactness of the present utility model can also effectively reduce the radiated interference that its discharge is produced, thereby can meet the requirement of the magnetic compatibility standard of electromagnetic induction electrodeless lamp fully.Electromagnetic induction electrodeless lamp of the present utility model is simple in structure, and is easy for installation, is suitable for large-scale production.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of electromagnetic induction electrodeless lamp of the present utility model.
Embodiment
Embodiment 1, Fig. 1 have provided a kind of electromagnetic induction electrodeless lamp, comprise the annular closed fluorescent tube 1 of uniform diameter, and the closed fluorescent tube 1 of this annular is annular; The cross section of the closed fluorescent tube 1 of annular is an oval ring.Inner surface at the closed fluorescent tube 1 of annular is provided with fluoresent coating 2; Be filled with ionogenic filling material 3 in the inner chamber of the closed fluorescent tube 1 of annular, this ionogenic filling material 3 is the charges that amalgam and inert gas are formed.Have the outer surface of the ring type magnetic core 4 of coil 5 around the closed fluorescent tube 1 of annular, the inner ring diameter of ring type magnetic core 4 is slightly greater than the external diameter of the closed fluorescent tube 1 of annular, outer surface at ring type magnetic core 4 is provided with anchor ear 8, under the fastening effect of anchor ear 8, ring type magnetic core 4 firmly is fixed in the outer surface of annular closed fluorescent tube 1.This ring type magnetic core 4 is one-piece type closed loop magnetic core.Ballast 7 links to each other with coil 5 by lead 6.
Electromagnetic induction electrodeless lamp of the present utility model is during practical set: utilize the separating opening on the annular closed fluorescent tube 1 that ring type magnetic core 4 is enclosed within on the annular closed fluorescent tube 1 earlier, thereby make the outer surface of ring type magnetic core 4 around the closed fluorescent tube 1 of annular; Utilize anchor ear 8 then, make ring type magnetic core 4 firmly be fixed in the outer surface of annular closed fluorescent tube 1; When being full of ionogenic filling material 3 in the inner chamber of the closed fluorescent tube 1 of annular, the separating opening on the closed fluorescent tube 1 of annular is closed hermetically, thus the inner chamber of annular closed fluorescent tube 1 and isolate from outer air.
At last, it is also to be noted that what more than enumerate only is a specific embodiment of the present utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged, and for example changes the shape of annular closed fluorescent tube 1.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection range of the present utility model.
