See that TV is an indispensable thing in modern people's life, see that the time of TV is more and more longer, the electron radiation injury increases the weight of day by day.People wish to have the less new television models of a kind of radiation to occur already.
At present television set producer in the situation aspect the television set improvement is: the electronic circuit part is many with miniaturization, integrated and be digitized as the master, and the picture tube aspect is based on dull and stereotyped right angle large-screen.Because screen has caused volume to heighten after increasing, machine heavily increases, radiation strengthens, so be difficult to solve above-mentioned three kinds of shortcomings.
Existing dull and stereotyped liquid crystal TV set occurs, but price is very expensive, is difficult in general family and popularizes.Also have a kind of television set protective cover, but not ideal enough because of effect, old friends are used few.
Also have a kind of projection TV set on the market, be mainly used in the public place of entertainment, its advantage is that volume is little, in light weight, radiation is few, watches but must establish screen in addition in the darkroom, and its image augmentation is realized by light diffusion irradiation in air.
Relatively domestic television set and projection TV set can be found: the former advantage is the latter's a shortcoming, and promptly clear picture needn't be watched in the darkroom; And the latter's advantage is the former shortcoming, and promptly volume is little, in light weight, radiation is few.
For this reason, we attempt to seek a kind of new technology, new material, and both advantages are got up, and overcome its shortcoming, produce a kind of new television models, satisfy people's needs.
The appearance of optical fiber is the key that addresses the above problem.Optical-fibre communications, fibre optic image transmission are the new and high technologies that the seventies rises, in 30 years, optical-fibre communications has obtained fast development, has goed deep into every field, the fibre optic image transmission technical development is slower, just is applied in certain fields such as military affairs, astronomy, medical science.But along with the development of optical fiber industry, relevant biography has now been developed the fiber products of a lot of materials as the maturation of technology, and particularly plastic fiber is cheap, passes fine as effect, rising greatly in closely.Promptly made one " spectrograph is to star coupler " eighties as China, it makes 4 * 5cm with 60,000 φ, 18 micron fiber bundles
2Square formation, the application of succeeding.Existing image converter tube uses in the military engineering, then yet there are no report on the TV but fibre optic image transmission is applied to.
In view of above-mentioned, the purpose of this utility model is the design environmental protection television machine that a kind of volume is little, in light weight, radiation is few.
The purpose of this utility model is achieved in that
A kind of environmental protection optical fiber television machine, comprise casing and be contained in casing interior small size picture tube and electronic circuit, it is characterized in that: the fluorescent glass screen of area greater than small size crt screen area, splicing optical fibers tread assembly between fluorescent glass screen and the crt screen are equipped with in described casing front.
Described fiber bundle assembly is made of the panel one at optical fiber identical with the crt screen pixel number and optical fiber two ends, each optical fiber is lined up array by the pixel location of crt screen, and the panel at two ends is respectively with identical with the overall dimension of the crt screen of its connection, fluorescent glass screen.
The panel at described fiber bundle assembly two ends is bonding with crt screen, fluorescent glass screen respectively.
The cross section of described every optical fiber increases gradually from its small panel one end to big panel one end.
Because the utility model adopts above technical scheme, so have following advantage:
Since in the panel of fiber bundle assembly the panel that connects with the fluorescent glass screen greater than the panel that connects with crt screen, make the image in the small screen picture tube after the transmission of fiber bundle assembly, can be extended to big image, former only the need just can obtain large-screen image with little picture tube, thereby reduced casing size and machine weight;
2. because but the optical fiber windup-degree makes two panels of fiber bundle assembly vertical mutually, so casing can change over flat casing and reduced volume by cube;
3. because electron ray is not to enter air but enter optical fiber, and the density of fiber optic materials is greater than the density of air, can impel electron ray to decay rapidly, cause the electron ray that penetrates from the fluorescent glass screen to remain little, so significantly reduced the injury of electron ray to human body;
4. owing to can reduce the deflection angle of deflecting coil behind the little picture tube of employing,, has power savings so can reduce the power of deflecting coil.
