Abstract
The utility model relates to a nonpolar long service life lamp which comprises a discharge bulb 1 and a ballast, wherein the discharge bulb 1 comprises a hollow cavity 2 filled with inert gases after evacuated and filled, and a mercury globule storage tube 3 which is positioned in the center of the discharge bulb 1 and is communicated with the hollow cavity 2. A hollow magnetic cylinder 4 is sheathed outside the mercury globule storage tube 3, and a magnetic core coil 5 is sheathed outside the hollow magnetic cylinder 4. The utility model is characterized in that the sealing position of the discharge bulb 1 is directly sealed by a lamp cap 6; the ballast and the discharge bulb are separated to form a split whole lamp. The nonpolar long service life lamp has the advantages of compact structure and small size. Thus, at the time of work, the ballast can not be influenced by the heating of the discharge bulb to extend the service life of the whole lamp. Because the lamp cap is directly sealed in the sealing position of the discharge bulb, the utility model has the advantages of compact structure, small size, broad use range and long service life.
Description
The utility model belongs to the novel illumination light source of the electrodeless and filament that a kind of indoor and outdoor lighting uses, and is specifically related to a kind of compact conformation, whole lamp perfect heat-dissipating, the ballast temperature rise is low, the life-span is long electrodeless long-life lamp.
Chinese patent 96240221.4 discloses a kind of HF lamp without electrodes.This HF lamp without electrodes mainly comprises a discharge bulb and a ballast that is connected with the magnetic core coil of bulb by lead-in wire, above-mentioned discharge bulb comprises that a cavity that is filled with inert gas after vacuumizing sealing and one are positioned at the globule storage tube bulb center, that communicate with cavity, sheathed one hollow magnetic cylinder outside the globule storage tube, and outside hollow magnetic cylinder a sheathed again magnetic core coil, ballast is placed in the semicircular arc heat radiation lampshade that is connected with the discharge bulb lamp holder.This HF lamp without electrodes is because ballast, fluorescent tube and heat radiation lampshade are formed the whole lamp of integral type, and the hot major part that fluorescent tube produces during work can be delivered on the electronic device of ballast, can seriously damage electronic device, thereby shorten the life-span of whole lamp; Because adopted a semicircular arc lampshade heat radiation that volume is bigger, its scope of application has been subjected to very big restriction, as in the place of using Down lamp, then can't install.
The purpose of this utility model provides a kind of compact conformation, whole lamp perfect heat-dissipating, the ballast temperature rise is low, the life-span is long electrodeless long-life lamp.
Electrodeless long-life lamp of the present utility model, comprise a discharge bulb and a ballast that is connected with magnetic coil in the above-mentioned discharge bulb by lead-in wire, above-mentioned discharge bulb comprises that a cavity that is filled with inert gas after vacuumizing sealing and one are positioned at the globule storage tube bulb center, that communicate with cavity, sheathed one hollow magnetic cylinder outside the globule storage tube, and outside hollow magnetic cylinder a sheathed again magnetic core coil, it is characterized in that directly encapsulating a lamp holder at the sealing part of discharge bulb, ballast separates formation one split type whole lamp with discharge bulb.
Electrodeless long-life lamp of the present utility model, described ballast are the ballasts that a kind of all-metal of filling glue is sealed.
Electrodeless long-life lamp of the present utility model, because the sealing part of discharge bulb is directly encapsulated a lamp holder, ballast is separated with discharge bulb constitute a split type whole lamp, ballast can not be subjected to the influence of discharge bulb heating when therefore working, thereby has prolonged the life-span of whole lamp; Sealing part at discharge bulb directly encapsulates lamp holder, makes compact conformation, and volume reduces, thereby has enlarged the scope of application of whole lamp; Because ballast adopts encapsulating and all-metal to seal, and has avoided the interference of external magnetic field to ballast, and has played shielding action, makes the temperature rise of ballast low, long service life is stable and reliable for performance.
Below in conjunction with accompanying drawing electrodeless long-life lamp of the present utility model is described further:
Fig. 1 a, Fig. 1 b, Fig. 1 c, Fig. 1 d are the assembling schematic diagrames of the discharge bulb of electrodeless long-life lamp of the present utility model.
As shown in the figure, electrodeless long-life lamp of the present utility model is the split type whole lamp that a kind of ballast separates with discharge bulb.Discharge bulb 1 wherein comprises that a cavity 2 that is filled with inert gas after vacuumizing sealing and one are positioned at globule storage tube 3 discharge bulb 1 center, that communicate with cavity 2, sheathed one hollow magnetic cylinder 4 outside globule storage tube 3, and outside hollow magnetic cylinder 4 a sheathed again magnetic core coil 5, directly encapsulate a lamp holder 6 at the sealing part of discharge bulb 1.
When the ballast energized, the high-frequency electrical component that ballast produces produces high frequency magnetic field through discharge bulb lamp holder 6 and the magnetic core coil 5 that is set on the globule storage tube 3, this high frequency magnetic field will excite the inert gas in the electrodeless bulb to produce arc discharge, the UV-irradiation that produces during discharge excites the bright visible light of generation to be used for illumination on electrodeless bulb inwall fluorescent coating.
Claims (2)
