Description
Technical field
The utility model relates to a kind of entire body optical fiber, more specifically to a kind of lateral emitting optical fiber.
Background technique
Lateral emitting optical fiber is also entirely lighting optical fiber, due to can arbitrarily be bent and moulding, can carry out a little shining, line
Shine and arbitrarily transformation color, have many advantages, such as safety, energy-saving and environmental protection, non-maintaining and long service life and be used widely.
At this stage, during lateral emitting optical fiber is chiefly used in illumination, decoration is decorateed.According to the core material material of entirely lighting optical fiber, can be divided into solid
State core entirely lighting optical fiber and liquid core entirely lighting optical fiber.Solid core entirely lighting optical fiber core material mainly has quartz, multicomponent
Glass and polymer.Liquid core entirely lighting optical fiber core material is the liquid such as silicone oil, its advantage is that flexibility is good, brightness is substantially equal
It is even.But liquid core entirely lighting optical fiber manufacturing process trouble, is unable to on-site cutting, can only customized lengths.
The above-mentioned most significant feature of entirely lighting optical fiber is that entirely lighting intensity exponentially declines with the increase of length, because
And it is difficult to use in in the demanding occasion of uniformity of luminance.
In recent years, the development of liquid crystal display (LCD) was advanced by leaps and bounds, in the with a very important position of flat display field.
Traditional backlight for liquid crystal display source generally has electroluminescent formula (EL), cold-cathode tube and light emitting diode (LED) etc. several.
Electroluminescent formula backlight generates electromagnetic interference using electroluminescent smooth principle while optical illumination, and its surface is bright
It spends also weaker.Cold-cathode tube light source, needs high pressure to excite, so it must be equipped with inverter to trigger.Due to by spatial position
Limitation, it is not suitable for using in small-size liquid crystal displays.And existing LED type backlight, it is general there are two types of
Lighting method.One is light emitting diode in the side equidistant intervals arrangement of light guide plate, is passed through the surface astigmatism of light guide plate
Example forms area source.It shines since light emitting diode crystal is that omnidirectional is dotted, it is very low with the coupling efficiency of light guide plate, can not
What is avoided causes the waste of luminous energy.Furthermore due to being alternatively arranged for light source, the surface light uniformity of light guide plate is poor.It is another
Kind arrangement mode is to arrange light emitting diode matrix to form area source.Although such backlight have higher brightness and uniformly
Property, but its power consumption and volume are all larger.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide one kind can radial 360 degree and it is axial
Even luminous lateral emitting optical fiber.
The technical solution of the utility model is as follows:
A kind of lateral emitting optical fiber is provided with several scattering points in the optical fiber of transparent cylinder.
Preferably, scattering point is arranged in the axis line inside of optical fiber.

It is gradually reduced.
Preferably, the surface of transparent cylindrical body plastic optical fiber is smooth.
Preferably, the diameter of optical fiber is 0.25mm-1mm.
Preferably, scattering point is the scattering region of the variations in refractive index formed in optical fiber by laser marking.
The beneficial effects of the utility model are as follows:
Lateral emitting optical fiber described in the utility model is provided with several scattering points in the optical fiber of transparent cylinder, scatters
Point is non-uniformly distributed according to certain rules in the axis line inside of optical fiber, i.e. the direction along light incident side to light exit side, adjacent
Spacing between scattering point is gradually reduced, then the lateral emitting intensity of the utility model does not generate index decreased with the increase of length
Phenomenon.If being used as the backlight of liquid crystal display, so that it may obtain that thickness is small, uniformity of luminance is good, flexible design back
Light source.Scattering point is placed in inside of optical fibre, keeps optical fiber surface smooth, avoids influence of the factors such as extraneous dust to scattering point.
Scattering point is the scattering region for the variations in refractive index processed inside plastic optical fiber using laser marking machine, and realization rate is high
Effect, simple process, quality are stablized.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1 is optical fiber, and 2 be scattering point.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
The present invention is in order to solve existing for the solid core entirely lighting optical fiber and liquid core entirely lighting optical fiber of the prior art
The deficiencies of performance is poor, process cumbersome, provides a kind of lateral emitting optical fiber, as shown in Figure 1, setting in the optical fiber 1 of transparent cylinder
There are several scattering points 2.In the present embodiment, the diameter of optical fiber 1 is 0.25mm-1mm, and material is common plastics optical fiber 1, plastic optical fiber
1 can be phase step type plastics optical fibre 1 or gradational plastic optical fibre 1, which is the smooth transparent cylindrical body in surface, scattering
Point 2 is arranged in the axis line inside of cylindrical body plastic optical fiber 1.In the present embodiment, processed using laser marking method several
A scattering point 2, i.e. scattering point 2 are the scattering region of the variations in refractive index formed in optical fiber 1 by laser marking.
Scattering point 2 is non-uniformly distributed according to certain rules in the axis line inside of optical fiber 1, and the rule is along light incidence
To the direction of light exit side, the spacing between adjacent scattering point 2 is gradually reduced at end.I.e. the regularity of distribution is that the light of plastic optical fiber 1 enters
Penetrating end --- being the right side of plastic optical fiber 1 in Fig. 1 ---, the spacing of scattering point 2 is big, and in the other end of plastic optical fiber 1, scattering
The spacing of point 2 is small, and the size and shape of scattering point 2 is constant.Scattering point 2, which is placed on central axes, can make optical fiber 1 in radial direction
360 degree of uniformly light-emittings, the light incident side of plastic optical fiber 1The spacing of scattering point 2 is big, the closely spaced arrangement of other end scattering point 2
Mode can make optical fiber 1 in axial uniformly light-emitting.
Above-described embodiment is intended merely to illustrate the utility model, and is not used as the restriction to the utility model.As long as
According to the technical essence of the utility model, above-described embodiment is changed, modification etc. will all fall in the right of the utility model
In the range of it is required that.
