Abstract
The utility model discloses a divergent optical fiber structure, it has the one deck glass pearl at the cladding have the optical fiber structure periphery of cortex, and make glass pearl and optical fiber core surface contact, optical fiber cortex thickness is less than glass pearl diameter, it can not only transmit light, but also can send the scattered light through the glass pearl, make optic fibre become the optic fibre of from peripheral divergent light, it is used in advertisement preparation and light pattern display, can directly arrange pattern or object profile with optic fibre linearity, can replace the neon fluorescent tube to show various multicolour patterns completely, it has simple manufacture craft, low cost, convenient to use, the picture is clear, advantage that visual effect is good.
Description
The utility model belongs to the improvement of optical fiber structure
The material that optical fiber generally adopts high index of refraction as core material, use material than low-refraction to coat to form as cortex, core material adopts glass, plastics and macromolecular material.And the material of cortex adopts organic siliconresin and bright olefin(e) acid resinoid more.Form total reflection with the Optical Fiber Transmission luminous energy of this structure between fibre core and degree layer, when skin thickness during greater than the half-wavelength of transmission light, its light can not revealed from the periphery of optical fiber, and all light then is constrained in the fiber cores and transmits.The optical fiber of this structure is widely used in billboard, multiple spot illumination demonstration and decoration painting and design at present, and the use in these fields all is to delineate object, lines, font and pattern in the mode that multiple spot is expressed.So when making, must insert substrate with optical fiber one by one and carry out permutation and combination, utilize each end face of optical fiber to form required pattern and profile, so manufacturing process extremely bothers, time-consuming taking a lot of work, face and since the optical fiber bright spot between the interval, the line image that demonstrates is not connected be used to, visual effect is undesirable.
The purpose of this utility model provide a kind of can be transmission light from the optical fiber structure that optical fiber surrounding comes out, make its have simple in structure, make advantage easy, easy to use.
The technical solution of the utility model is to realize like this, the structure of designed divergence form optical fiber is to be coated with cortex in the fibre core periphery, and be enclosed with one deck bead in the optical fiber periphery, bead is contacted with the fibre core outer surface, and skin thickness is less than the diameter of bead.Feature of the present utility model also is, wraps up one deck bead again in the periphery of above-mentioned divergence form optical fiber, and outer field bead is contacted with the bead of internal layer, and the diameter of its bead can be chosen in 0.2～0.5mm.
Because the utility model is enclosed with bead and contacts with fibre core on optical fiber, and the cylindroid of fibre core periphery is cut to a contact mutually with the bead contact point, transmission light in the fibre core just can enter bead by contact point so, and scatter out by bead, the face that contacts with bead is not then by the cortex total reflection, still constrain in and continue transmission in the fibre core, so just formed the Transmission Fibers of peripheral energy diverging light.If adopt divergence form optical fiber of the present utility model to come pattern-making, delineate object, show lines etc., then directly reach with the linear display list of divergence form optical fiber, need not to insert one by one again substrate manufacture, can delineate out the pattern and the contour of object of required expression with divergence form optical fiber direct cable, it can also substitute neon light tube and show linearity pattern.So divergence form optical fiber of the present utility model has linear characteristics showed, it shows svelteness, good visual effect, and is more much lower than the cost of neon light tube, has simple in structurely simultaneously, makes advantage easy, easy to use.
Below in conjunction with accompanying drawing enforcement of the present utility model is elaborated.
Accompanying drawing 1 is the structural representation of the designed divergence form optical fiber of the utility model (radial section amplification).1 is fiber cores among the figure, and 2 is the optical fiber cortex, and 3 is bead.
Referring to accompanying drawing, the fibre core of designed divergence form optical fiber should select flexible plastics and macromolecular material for making things convenient for decorative pattern, as poly-bright olefin(e) acid methyl esters of methyl or polyphenyl hexene etc.; Cortical material can be selected organic siliconresin or bright olefin(e) acid resinoid etc. for use; The diameter dimension of bead can be limited to 0.2～0.5mm, if double-deck bead of parcel, the diameter of its inner layer glass pearl is less than outer field bead diameter.When making, earlier fibre core is evenly applied cortex, again it is imported bead box and passes through and pull out, its surface evenly is stained with one deck bead, rely on pearl and core affinity the two contact naturally, drying again, the convergent force of dependence cortex is then tightly fixing with bead; If need wrap up one deck bead more then before oven dry, apply one deck cortical material again, make it connect sticking one deck bead again, oven dry at last gets final product.Become commodity through segment, bundle handle again.
Divergence form optical fiber structure of the present utility model in use, only needing that it is pressed the layout lines arranges fixing, again its optic fibre end is docked with ordinary optic fibre, light is through ordinary optic fibre input divergence form optical fiber, bead by the divergence form optical fiber surrounding scatters out, and can demonstrate the pattern of being delineated.Can certainly be made as one to divergence form optical fiber and ordinary optic fibre.
