Abstract
The utility model discloses a novel supercompact plane light source with compactness and greatly improved mechanical strength. The utility model uses electric discharge pipes of conduplicate or multifolding pipes of which the outsides are stuck into a whole, and the insides are clear; the utility model can be made into a supercompact plane fluorescent lamp, an ultraviolet plane light source, a flat neon lamp, or other light sources, etc. The novel supercompact plane light source of the utility model has the advantages that the structure is compacter than that of a lamp tube made in the traditional method, and the mechanical strength, the brightness and the evenness are greatly improved.
Description
Technical field
The utility model relates to a kind of novel ultra-compact planar light source, especially a kind of novel cold cathode ultra-compact plane fluorescent lamp source.
Background technology
The planar light source of prior art made (no matter fluorescent lamp, ultraviolet source or other kind light sources are all identical) generally all is to use many U type light pipe that long glass-tube plane is bent into.But this many U of being bent into type light pipe generally can stay some spaces between light pipe, be difficult to accomplish very compact.Especially (planar light source of<5mm=because the intensity of this light pipe is too poor, very easily damages for superfine pipe diameter.
Summary of the invention
The purpose of this utility model is to provide a kind of more compact, the novel ultra-compact planar light source that mechanical strength significantly improves.
For reaching above purpose, the utility model has been taked following technical scheme: the utility model planar light source use outside cohere be integral, inner unimpeded two-fold or roll over the discharge tube of pipeline more.Described discharge tube adopts following method preparation: when making this cold cathode ultra-compact fluorescent lamp, with the bent folding light pipe, be heated to the above proper temperature of softening point, place on the channel mould type platform 1 (Fig. 1) that the graphite that preheats appropriate temperature or other exotic materials make, cover graphite or other exotic material cover plates 2 that is preheating to relevant temperature above, with push rod 3 pushings of the die cavity outside outside of each adjacent light pipe is melted again and fuse to form the light pipe of multitube disjunctor.The outside of light pipe fuses like this, but the pipeline of folded inside is still unobstructed, can make a planar light source.
Inwall at this light pipe is coated fluorescent material, respectively adds a cold cathode or hot cathode at two ends of pipeline, and fluorescent tube is bled and charged into suitable gas and mercury or amalgam promptly can be made into cold cathode or hot cathode ultra-compact flat florescent lamp; If coating fluorescent powder not, in described discharge tube, charge into inert gas and mercury or amalgam and then can be made into the ultraviolet planar light source, comprise compact U type, roll over plane ultraviolet source or microminiature ultraviolet source etc. more, also can charge into mists such as neon and make plane neon light or other light sources.
The structure of novel ultra-compact planar light source of the present utility model is more compacter than the fluorescent tube of making of conventional method, and mechanical strength, lamp brightness and the uniformity increase substantially.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model content is described further:
As described in Figure 1, when making cold cathode ultra-compact plane fluorescent light source, the long 660mm that will select earlier, the glass tube of diameter 10mm bends to 8 foldings, every segment length 80mm, two ends respectively stay ± 10mm, this glass tube 4 is heated to 700 ℃~800 ℃ to be placed on the graphite cuvette model platform 1 that preheats 600 ℃, cover above and be preheating to 600 ℃ graphite cover plate 2, pass push rod 3 again in the die cavity outside each adjacent glass Guan Rong is fused to form many foldings pipe of disjunctor, this pipe outside fuses but the pipeline of folded inside is still unimpeded.
Coat fluorescent material at above-mentioned tube inner wall, and respectively add an electrode at two ends of pipe, after be pumped to vacuum after, charge into argon gas and an amount of mercury, promptly can be made into the ultra-compact flat florescent lamp (as Fig. 3) of cold cathode.
Employing length is that the external diameter of 400mm is the quartz ampoule of 10mm, internal diameter 8mm, bends to the bar-shaped disjunctor U-shaped pipe that U-shaped heats compacting growth 200mm, wide 16mm, thick 8mm again.Two ends respectively install an oxide coated cathode, charge into an amount of mercury in the lamp, promptly make single U disjunctor ultraviolet light source.
Claims (4)
1, a kind of novel ultra-compact planar light source is characterized in that using the outside to cohere and is integral, inner unimpeded two-fold or roll over the discharge tube of pipeline more.
2, novel ultra-compact planar light source as claimed in claim 1 is characterized in that coating fluorescent powder in described discharge tube, and technology is made the compact planar fluorescent lamp routinely again.
