A kind of optics module using matrix form optical baffle
Technical field
Field of optical systems more particularly to a kind of use matrix form optics the present invention relates to automobile headlight low beam design The optics module of baffle.
Background technology
For a long time, automotive lighting is the emphasis of numerous automobile vendors and client's concern safely.With the development of technology, square Configuration high beam is announced to the world splendidly.Matrix form high beam is usually by plurality of LEDs assembled arrangement, by automobile sensor for difference Scene individually control the light on and off of single LED light source, light type is enable to brake adaptation environment.Because matrix form high beam is dazzled extremely Intelligence and increased lighting safety have become the trend and wind direction of car light design.Matrix form high beam passes through many independent Small optical system form, it is crucial that the optical system of high efficient and reliable becomes its.
Existing matrix form high beam, due to the limitation of technology, it usually needs dedicated optical system realizes required work( Energy.Matrix form road function is realized generally by the combination of a module or two or three of modules, results in cost in this way Increase the waste with expensive real estate.
Invention content
To solve the above-mentioned problems, the object of the present invention is to provide a kind of optics module using matrix form optical baffle, Dipped beam and matrix form distance light integrated design, can be significantly since dipped beam system and distance light system can share many components Reduce module size and cost, and have very high light transmittance efficiency utilization rate, therefore better light can be provided for matrix form high beam Learn system scheme.
The present invention provides a kind of optics module using matrix form optical baffle, including dipped beam LED light source, distance light LED light Small front apron under source, dipped beam projecting lens, distance light projecting lens, optical baffle, condenser lens and optical baffle, the dipped beam are thrown Shadow lens are arranged on dipped beam LED light source forepart, and the distance light projecting lens is arranged on distance light LED light source forepart, described to focus on thoroughly Mirror is arranged on the right side of dipped beam projecting lens and distance light projecting lens, and the condenser lens and dipped beam projecting lens and distance light projection are thoroughly Optical baffle is provided between mirror, the optical baffle lower part is provided with small front apron.
Further improvement lies in that:The light that the dipped beam LED light source projects passes through dipped beam projecting lens, the distance light LED light The light that source is projected is reflected by optical baffle by distance light projecting lens and is cut dipped beam light type and emit distance light light type.
Further improvement lies in that:The optical baffle is in tabular, and the reflectivity on positive and negative surface is realized to source light Effective reflection, the edge shape of the optical baffle is arc-shaped, to realize the clear smooth of the "cut-off"line of dipped beam.
Further improvement lies in that:The material of the dipped beam projecting lens and distance light projecting lens is makrolon or silica gel etc. High-temperature resistance plastice material.
Further improvement lies in that:The condenser lens is convex lens, and inner surface is plane or curved surface.
Further improvement lies in that:The material of the condenser lens is generally the high poly methyl methacrylate plastic of light transmittance Or glass material.
Using horizontal positioned optics of metals baffle with high reflectivity as line of demarcation, dipped beam LED light source and distance light LED light Source is located above and below optical baffle rear side respectively, and dipped beam LED and distance light LED are arranged by horizontal direction, are increased with this Light type range of scatter in the horizontal direction places dipped beam projecting lens, in front of distance light LED light source in front of dipped beam LED light source Distance light projection lens is placed, the projecting direction of source light is determined with this, a dipped beam light part is cut by optical baffle upper surface It cuts and reflects, the shape at optical baffle edge can be cut into the shape of "cut-off"line, and a part is directed across optical baffle, All light of dipped beam all focus on to form dipped beam light type by condenser lens.Distance light light also passes through after distance light projecting lens Optical baffle, and have some light to be blocked by the small front apron below optical baffle after condenser lens and then forms matrix form Distance light light type.The dipped beam and distance light light type that the optics module is formed are smoothly clear, and light distribution is uniform, and light utilization is high, knot Structure is compact.
The dipped beam projecting lens and the distance light projecting lens are free-form surface lens, and light-emitting surface is curved design.
The optical baffle is high reflectance optical metal baffle, and small front apron number below can be according to matrix form The dark space number of distance light is designed accordingly.
The condenser lens is convex lens, and inner surface is generally plane, can also be optimized for convex surface to reduce lens Thickness.
Generally there is microstructure design in the condenser lens outer surface, to generate good gradient and with optical uniformity.
The beneficial effects of the invention are as follows:Nearly photosystem and matrix form distance light system combines in vertical direction, By the design of a shared optical baffle and condenser lens, dipped beam and matrix form road function are realized using a module, Substantially reduce the space requirement for realizing two kinds of functions.Simultaneously as the luminous energy being reflected in optical baffle can be made full use of, The module almost can completely use the light sent out from light source part, therefore optical property significantly improves.
