Description
Technical field
The present invention relates to a kind of method for eliminating light guide speck and double-colored light guides, belong to car light manufacturing technology field.
Background technology
As shown in Figure 1, usually light guide is the light guide installation foot 1 by being arranged thereon and the relational structure in other parts 2
The fixing that matches realizes that installation is fixed.A part of the light guide installation foot angle as entire light guide product, is same with light guide body 3
Kind material is integrally formed.Perfect condition is that the light in light guide body is all propagated by total reflection from one end to the other side,
However the presence of light guide installation foot always makes a part of light change propagation path when encountering light guide installation foot.Such as Fig. 1 institutes
Show in structure have some light that can pass through light guide body and inject light guide installation foot, the directive light guide again of the refraction through light guide installation foot
The light guide tooth of bottom part body is projected from the front of light guide body again after being reflected by light guide tooth.In the front of light guide body (with light
It is opposite to lead face where tooth) under visual angle, this some light is formed " speck ".Speck is that have technology to be solved in light guide design
Problem.
Invention content
To solve the above problems, the present invention provides a kind of method for eliminating light guide speck and double-colored light guide, it can be thorough
Eliminate speck.
The main technical schemes of the present invention have：
A method of light guide speck is eliminated, light guide installation foot is made using dark translucent material.
It is preferred that making light guide installation foot using black transparent material.
Further, can be by double-shot moulding light guide, and so that light guide body and light guide installation foot is separated and noted twice
It is molded in modeling, wherein the light guide installation foot material therefor is through hyperchromatic PC materials or PMMA materials, the light guide master
Body material therefor is the PC materials or PMMA materials of no dyeing.
A kind of double-colored light guide, including light guide body and light guide installation foot, the light guide body and light guide installation foot be not using
Translucent material with color makes, wherein the light guide installation foot is molded using dark material.
The light guide installation foot material therefor is preferably black.
The light guide installation foot material therefor is through hyperchromatic PC materials or PMMA materials, used in the light guide body
Material is the PC materials or PMMA materials of no dyeing.
The double-colored light guide is that double-shot moulding product, the light guide body and light guide installation foot are molded for not homogeneous.
The light guide installation foot is the spaced diameter convex structure of length direction along the light guide body.
Multiple light guide installation feet are correspondingly arranged on one light guide body.
The beneficial effects of the invention are as follows：
Due to making the material of light guide installation foot into dark even black by colourless, it is refracted to the light of light guide installation foot
It will be most of or even be all absorbed, also would not be again to the refraction of light guide toothed portion, therefore completely eliminate speck, hence it is evident that change
Kind light guide lights effect.
Achieve the purpose that eliminate speck using the present invention, light guide installation foot and other structures for being associated mounting structures are set
The flexibility ratio of meter increases, and is on the other hand also beneficial to the simplification of structure, in a word due to can exclude an important misgivings because
Element, therefore the structure design difficulty of light guide can be substantially reduced.
Description of the drawings
Fig. 1 is that existing light guide fixes position cross-sectional view；
Fig. 2 is that the light guide of one embodiment of the double-colored light guide of the present invention fixes position cross-sectional view.
Specific implementation mode
The invention discloses a kind of method for eliminating light guide speck, core is to make light guide peace using dark translucent material
Foot is filled, the light into light guide installation foot is made to be absorbed, will not be propagated again to other directions, therefore the production of speck will not be caused
It is raw.
It uses black transparent material to make the light guide installation foot as a preferred technical solution, makes to enter light guide installation
Whole light of foot are all absorbed, and so that speck is eliminated more thorough.
Further, can be by double-shot moulding light guide, and so that light guide body and light guide installation foot is separated and noted twice
It is molded in modeling, wherein the light guide installation foot material therefor is through hyperchromatic PC materials or PMMA materials, the light guide master
Body material therefor is the PC materials or PMMA materials of no dyeing.
The invention also discloses a kind of double-colored light guides, as shown in Fig. 2, including light guide body 3 and light guide installation foot 1, it is described
Light guide body and light guide installation foot are made of the translucent material of different colours, wherein the light guide installation foot uses dark material
It is molded.It, will not be again to light guide toothed portion since most of light for being refracted into light guide installation foot can all be absorbed
Refraction, would not also generate speck.
The double-colored light guide can carry out further optimization design in following one or more aspects.
The light guide installation foot material therefor is preferably black, and the light into light guide installation foot is made all to be absorbed, thorough
Eliminate speck in bottom.
The light guide installation foot material therefor can be through hyperchromatic PC materials or PMMA materials, the light guide body
Material therefor is then the PC materials or PMMA materials of no dyeing.In addition to color, the light guide installation foot and the light guide master
Material used by body may be the same or different.
The double-colored light guide can be using dual-color forming mechanism make double-shot moulding product, the light guide body and
Light guide installation foot is molded for not homogeneous.
The light guide installation foot is the spaced diameter convex structure of length direction along the light guide body.One
Multiple light guide installation feet are usually correspondingly arranged on the light guide body.
After dark or black the light guide installation foot, the speck problem for perplexing light guide design always has obtained thoroughly
It solves.On this basis, no longer need to be intended to the structure design by changing light guide installation foot and the relational structure in other parts 2
Improve speck problem, to make it possible that the structure of light guide installation foot tends to simply, effectively reduce guide structure design
Difficulty.
Emphasize mainly to be emphasized with dark color herein using to the stronger color of the absorbability of light, for example, black, navy blue,
Brown, bottle green, Dark grey etc., in fact, compared to the general colourless translucent material of no dyeing, even if contaminated color is
Light color also has certain extinction effect, therefore also can reduce and eliminate to a certain extent speck.
