Background technology
In automobile lamp field, guide structure is more and more applied in automobile lamp.
At present the conduction realizing light with total reflection principle for the photoconduction in light fixture, optical component material be working of plastics (PC or PMMA), but the covering that its periphery does not have refractive index little, but directly utilize air as total reflection medium.
In the application of photoconduction,
The transmission of light in optical component or optical fiber, the water just with rubber tube is the same, and inject light from optical component or fibre-optic one end, even if curved by optical fiber, light also can follow optical component or optical fiber penetrates from the other end.
In the application of automobile lamp, due to the needs installed, optical component needs to do torsional bending in space, and other parts are due to the restriction of mould structure, often be difficult to follow optical component be out of shape simultaneously, thus cannot carry out optical component coated completely, like this, unnecessary light injection can be caused, light leak occurs.
Summary of the invention
For overcoming the problems referred to above, the object of the invention is to, providing a kind of photoconduction anti-light leakage structure, described photoconduction anti-light leakage structure is used for car light, particularly, for the light guide before car light photoconduction visibility region and light-emitting zone and light source and invisible part.
According to photoconduction anti-light leakage structure of the present invention, tie up to the elbow portions of optical component, a coated sleeve pipe with elastic deformation ability, described sleeve pipe can optical component fill in after return to original shape, thus complete coated optical component, the effect of the light leak that plays shield lights, prevents light leakage, occurs.
The technical scheme of photoconduction anti-light leakage structure of the present invention is as follows:
A kind of photoconduction anti-light leakage structure, the LED light comprised for automobile lamp leads component, it is characterized in that,
A kind of optical component sleeve pipe of described photoconduction anti-light leakage structure system, described optical component sleeve pipe is an elastomeric overmold sleeve pipe, curving or displacement part for optical component,
Described optical component sleeve pipe one side opening, can magnify do elastic deformation, is convenient to optical component to fill in wherein, and after described optical component is filled in, described optical component sleeve pipe can return to original shape, thus complete coated optical component shield lights,
The madial wall of described optical component sleeve pipe is provided with rib, make described optical component sleeve pipe madial wall, with optical component, linear contact only occur, thus, between described optical component sleeve pipe madial wall and optical component, there is the air as being totally reflected medium.
According to photoconduction anti-light leakage structure of the present invention, particularly, for the light guide (i.e. invisible part) before car light photoconduction visibility region (i.e. light-emitting zone) and light source.
Because the present invention adopts elastomeric material to be coated on photoconduction, eliminate buckle, the mount fixing structures such as screw.And shape is comparatively random, takes up room little.
According to the present invention, as the main element material of guide structure, adopt the filaments of glass that transparency is high, the filaments of glass that transparency is high, outside is surrounded by its much smaller crust covering of refractive index ratio.Like this, the light entering optical component can only occur to be totally reflected at the interface of heart yearn and crust covering along optical component and tortuously to advance, and can not through interface, and scattering is outside optical component or optical fiber.Its duty is just as being enclosed in tightly in optical component or optical fiber heart yearn by crust covering.
Thus ensure that the ATR Optical performance of optical component in described optical component sleeve pipe is unaffected.
According to a kind of photoconduction anti-light leakage structure of the present invention, it is characterized in that,
