Description

LED light source realizes the optical texture of light curtain effect and the car light with the structure
Technical field
The utility model relates to the optics that automobile lamp technical field more particularly to a kind of LED light source realize light curtain effect Structure and car light with the structure.
Background technique
Currently, automobile Rear Position Lamp mostly uses guide structure, the advantage of light guide is, can largely reduce LED Number, to reduce the price of entire car light；The light that LED light source can be issued is guided to the light-emitting surface of light guide, And then so that LED point light source is become uniform area source, thus light guide using more and more.
Use for light guide, more popular is the luminous application in face, realizes that the light curtain effect of car light mainly uses light The use of guide plate or light guide flange, but larger space need to be occupied and use more LED quantity, and do not emphasize light guide edges of boards The light-emitting area and light-emitting uniformity of edge.
Utility model content
The utility model provides a kind of LED light source and realizes the optical texture of light curtain effect and the car light with the structure, Space can be saved, cost is reduced, guarantees the light-emitting uniformity of lampshade in entire.
In order to realize the purpose of this utility model, used technical solution is: the optics of LED light source realization light curtain effect Structure, including interior lampshade, LED sub-unit and an at least LED light source, interior lampshade include light guide section and optical plate part, light It leads part to connect with optical plate part inlay, micro-structure is additionally provided on interior lampshade, LED sub-unit is located at the lower section of interior lampshade, LED light source is mounted on LED sub-unit.
As the prioritization scheme of the utility model, light guide section bends insertion optical plate part, light guide portion by deep camber Divide overall U-shaped structure, light guide section is connected with LED light source.
As the prioritization scheme of the utility model, microstructured ar-rangement growth bar shaped, circle or rectangular.
As the prioritization scheme of the utility model, micro-structure is in cone or elliposoidal.
In order to realize the purpose of this utility model, the technical scheme adopted is that a kind of car light, including above-mentioned LED light The optical texture of source realization light curtain effect.
The utility model has the effect of positive: 1) light guide section and optical plate part inlay connection group in the utility model At interior lampshade, integralization manufactures and designs, and can save light-guide material and install the use of fixed material, entire design is simpler About；
2) deep camber of the utility model design bends light guide, and be in U-shape structure, and comparison is conventional to be placed in light source by light guide Side, on the one hand, save light emitting region surrounding space, on the other hand, U-shaped design may make lampshade uniform in light emission in entire, special It is not the interior lampshade side edge of light source input terminal, and expands entire light-emitting area；
3) the utility model uses minute quantity LED light source, and the ingenious design using reflection micro-structure reaches light guide combination With the light-out effect of optical plate, only needs LED light source and monochromatic light to lead and be just able to achieve complicated light curtain effect；
4) reflection micro-structure designed by the utility model can arrange according to demand, facilitate design model, more flexible It is changeable, and without increasing material.
