Abstract

The present invention relates to an embossed optical fiber. It is an optical fiber whose whole or partial transparent sheath has concave-convex embossings or raster notch grooves, and a part of light passed through said optical fiber is ejected from those concave-convex embossings or raster notch grooves so as to make the optical fiber become a bright line segment or line segment with iridescence. Its manufacture is simple, and its application in the colored-lantern making craft is very extensive. It can be made into various new type optical fiber colored-lantern handicraft articles, articles of every day use and performance articles with light-colored face or light-colored line segment with iridescence, such as gaily decorated basket, stereoscopic wall picture and mosquito net, etc..

Description

Grained optical fiber

This invention is light transmitting fiber and method for making and the purposes that there are concavo-convex embossing or grating cutting in a kind of surface.

At present, according to fibre-optic leaded light principle, fibre-optic top layer is not allow the light outgoing as far as possible, the light transmitting fiber lantern handicraft of selling and putting on display on the market, its luminous component mainly is fibre-optic end place and some turning point, the photochromic effect of these lantern handicrafts is mainly from the photochromic point of light transmitting fiber end place and some turning point and the external irradiation of light source, wherein can not to show strip photochromic for the wall scroll light transmitting fiber, wherein in a row or the light transmitting fiber arranged of bunchy can not be by the cylinder of the light performance that send its inside plane in a row or bunchy photochromic, the change of its color is moving from light source place seven color slidies then.

The purpose of this invention is by light transmitting fiber is carried out suitable embossing, make the wall scroll light transmitting fiber can show strip photochromic, make in a row or light transmitting fiber that bunchy is arranged can show the photochromic of plane or cylinder, when embossing is grating cutting shape embossing, can there be the rainbow color on the light transmitting fiber surface and changes irregularly with viewing angle, can make thus than present kind and more have the light transmitting fiber lantern handicraft that more enriches photochromic pattern and make small portable and exquisite light transmitting fiber lantern handicraft attractive in appearance, be that life increases color.

For this reason, following method for making is selected in suggestion for use:

But the light transmitting fiber with the transparent crust of certain thickness of the compression moulding of straight certain-length is sent in the itemize groove of the continuous embossing machine of being made up of embossing template, cylinder, itemize groove, rotation with cylinder, the itemize groove comes the cylinder top of shaft parallel in ground to a rule light transmitting fiber with being parallel to roller shaft successively, and embossing template curved surface everywhere with cylinder surface apart from consistent and be in the side top of cylinder, the cylinder band light transmitting fiber light transmitting fiber after the embossing template and is dropped out, and finishes embossing.The cylindrical curvature of embossing template makes its cylinder be slightly smaller than by the fibre-optic diameter of pressure to the radial distance of cylinder cylinder, and template cylinder orphan is about to fibre-optic outer periphery is long, and the cylinder height of template is the length of light transmitting fiber pressed part section.Can require the embossing template of assembling different size and number according to different light transmitting fiber embossings.The embossing template can have various forms of mould lines near on the die face of cylinder, as perpendicular coarse groove, netted line, horizontal grating line or the like.The itemize grid of can burn-oning on the cylinder.

With the above-mentioned light transmitting fiber of making that concavo-convex embossing or grating cutting are arranged shear, paste, technology such as bending, braiding, add light source etc., can make various novel light transmitting fiber lantern handicrafts with photochromic.Can be on cap or knit cap constitute certain pattern or literal and load onto baby battery and bulb etc., make the photochromic color cap that to use for night in red-letter day and stage performance in the crown inboard with light transmitting fiber.These light transmitting fibers can be compiled the sticking miniature floriation of making, be equipped with baby battery and bulb light source in similar cap, make the miniature floriation can be not on pocket mouth, the hem, hair, it is late decorations good merchantable brand, also can be made into mosquito net and window screening, use the alternating current light source to produce another kind of fantasy atmosphere in night.

The advantage of the method for making of suggestion is that embossing machine manufactures easily continuously, and only need change the embossing template and regulate the embossing that its radial distance just can carry out various forms mould line, various embossing length and various embossing spacings to various diameter light transmitting fibers.Make light transmitting fiber behind the embossing can be fit to different lantern handicrafts and make needs.

Accompanying drawing is the sectional view of certain band light transmitting fiber on the plane of crossing its center line, and dotted line is represented the core-skin interface among the figure, and figure represents the axis fibre-optic center line.

Embodiment: adopt on the market in the light transmitting fiber lantern handicraft fibre-optic core and cladding to make light transmitting fiber or photoconduction strand, make needs according to different lantern handicrafts again and make various corresponding grained optical fibers or embossing photoconduction strand, make required lantern handicraft at last with the method for making of above-mentioned suggestion.
