Fig. 1 is a schematic structural diagram of a pattern of a vehicular lamp according to an embodiment of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a pattern of a light fixture for a vehicle, which is composed of a plurality of polygons or polygons (the polygons may include triangles, quadrilaterals, pentagons and hexagons, and the pattern may be composed of polygons or polygons with the same number of sides, or may be a combination of polygons or polygons with different numbers of sides); the single polygon is a generalized polygon, the vertexes of the generalized polygon are coplanar or coplanar, the edges of the polygon are curved, and the vertexes of the polygon are coplanar or curved; at least two polygons or polygon-like front projections are not exactly the same, and any adjacent polygons or polygon-like may intersect or be collinear.
Compared with the prior art, the pattern of the lamp for the vehicle has the following advantages:
in the pattern of the lamp for the vehicle provided by the embodiment of the invention, as shown in fig. 1, the pattern is composed of a plurality of polygons or quasi-polygons; the single polygon is a generalized polygon, the vertexes of the generalized polygon are coplanar or coplanar, the edges of the polygon are curved, and the vertexes of the polygon are coplanar or curved; at least two polygons or polygon-like front projections are not exactly the same, and any adjacent polygons or polygon-like may intersect or be collinear. From the analysis, the patterns of the vehicle lamp provided by the embodiment of the invention can ensure that the lighting effect is as bright as that of a night full of stars, and the appearance is as disordered, but the patterns have strong granular sense, and can play a role in beautifying the lamp well. The light distribution grain surface of the car lamp in the random pattern can randomly change the light path direction by the reflection, refraction or total reflection of light rays emitted by the light source, so that the direction of emergent light rays can be controlled by controlling the trend of the optical surfaces. In addition, if the light distribution patterns of the car lamp are added on the inner lens or the reflecting surface, the relative lighting uniformity can be ensured, the optical effect of partial diffusion can be realized, and meanwhile, different light and shadow effects can be realized by the patterns with random properties, so that the three-dimensional luminous characteristic is achieved.
The shape, the size and the edge number of the polygon or the similar polygon have randomness, and the limited curved surfaces corresponding to the bottom surfaces formed by the edges of the similar polygons also have randomness, namely, even if the shape, the size and the edge number of the two similar polygons are the same in orthographic projection, the two similar polygons are not completely the same as long as the corresponding limited curved surfaces are different; when the vertices of a single polygon or class of polygons are coplanar, the plane normal is random. When the light rays pass through the polygonal or polygonal-like pattern, the relative lighting uniformity is ensured, the light rays have an effective diffusion effect, and different light and shadow effects can be realized due to the randomness of the pattern, so that the luminous characteristics of the star are presented.
Specifically, the pattern is a polygon or a combination of polygon-like shapes with identical edges; or, the pattern is a random combination of polygons or polygon-like shapes with different edge numbers.
The vertices of each polygon are transformed by a quadrilateral lattice on the custom surface. Each class of polygon may be formed by changing any side of the polygon into a curve. The number of quadrilaterals can be adjusted by changing the number of discrete lattices, thereby changing the number of polygons or polygons and the projection shape.
The vertexes of each polygon can be positioned on the same plane or a custom curved surface, and if the vertexes of a single polygon or a similar polygon are coplanar, step differences can be formed among a plurality of polygons or similar polygons.
In practical application, each polygon is formed by defining discrete points on a custom curved surface according to any two directions, and then sequentially connecting two adjacent points to form a plurality of quadrilateral small unit areas; each class of polygon is formed by changing any side of the polygon into a curve.
Each vertex of the quadrilateral unit is offset by a random distance, and the offset vertices are connected to form a quadrilateral.
Each quadrilateral vertex is encrypted to a point array in two directions, the encrypted corresponding points are connected, and the quadrilateral array is divided into a hexagonal array.
Specifically, each vertex of the hexagon is offset by a random distance, and the offset vertices are connected to form the hexagon.
Specifically, the hexagons are split by connecting the vertexes, and triangles, quadrilaterals and pentagons are split to form random combinations of polygons.
Further, each polygon vertex is offset by a random distance, and the offset vertices are connected to form a polygon.
The method comprises the steps of encrypting a point array in one direction, sequentially connecting the newly inserted point with two vertexes of the original quadrilateral serving as vertexes, and forming a triangle.
Specifically, each vertex of the triangle is offset by a random distance, and the offset vertices are connected to form a triangle.
Further, any side of the polygon is changed into a curve to form a polygon-like shape.
The light distribution patterns of the car lamp can refract, reflect or totally reflect light rays at different angles to form diffusion through patterns which can be formed by optics, and the direction of the light rays can be controlled by purposefully controlling the inclination angles of the patterns.
On the premise of ensuring the lighting uniformity and the three-dimensional luminous effect, the edge number of the pattern polygon can be properly controlled so as to make the pattern structure as simple as possible and avoid the excessively complex processing.
When the light distribution pattern is actually applied, the light distribution pattern of the car lamp can be applied to a plurality of functions of the car lamp, for example, the light distribution pattern of the car lamp is arranged on the reflecting surface of the reflecting cavity (namely, the light is reflected and projected to the partial structure of the outer lens), the light emitted by the light source in the car lamp is reflected by the reflecting part with the light distribution pattern of the car lamp, the light is projected outwards randomly, the lighting effect is relatively uniform, and the luminous effect shows the characteristic of a star.
The embodiment of the invention also provides a method for producing the pattern of the lamp for the vehicle, which comprises the following steps: step S1, defining a closed area of a self-defined curved surface on which a light distribution line of a car lamp is to be generated; for a planar closed area, the boundary of the closed area should be a broken line; for a closed area of the curved surface, the boundary of the closed area is formed by sequentially connecting curves obtained by cutting the curved surface by a plurality of planes end to end and finally closing the curves; the light distribution lines are all to be arranged on a specific object surface, when the boundary of the object surface is a curve, the boundary regular curved surface overlapped with the curved surface can be used for replacing the light distribution lines, the patterns are generated on the boundary regular curved surface, and the final light distribution lines are obtained by cutting the custom curved surface. S2, defining discrete points according to any two directions for a closed area of the custom surface, wherein the discrete points are positioned on the custom surface; two adjacent points are sequentially connected in two directions, the curved surface closed area is divided into a plurality of quadrilateral small unit areas, each two adjacent small unit areas share one side, and each four small units share the vertex. Step S3, defining the random offset distance of each vertex; the random distance values of the offset are defined within a certain range to change the positional relationship among the plurality of patterns. S4, recording the offset position corresponding to each vertex, and projecting the offset points to the self-defined curved surface closed area according to the appointed direction; connecting two adjacent projection positions in two directions to form a quadrangle; according to the light distribution requirement, designating a direction as the normal direction of a plane, selecting any point of the quadrangle to pass through the plane, and projecting the other three vertexes of the quadrangle onto the plane to enable the vertexes of the quadrangle to be coplanar; any side of all quadrangles is changed into a curve to form a similar quadrangle.
In the step S4, the dot matrix is encrypted in two directions: a new point is inserted between two vertexes in one direction, three points are inserted into the two vertexes in two directions, and the original 2x2 lattice is converted into a 3x5 lattice to form a dense lattice; the points which are newly inserted in one direction are taken as vertexes, and the first point and the third point which are newly inserted in two directions are sequentially connected with six vertexes to form a hexagon; according to the light distribution requirement, designating a direction as the normal direction of a plane, selecting any point of the hexagon to pass through the plane, and projecting the other five vertexes of the hexagon to the plane so that the vertexes of the single hexagon are coplanar; any side of all hexagons is changed into a curve to form a quasi-hexagon.
Specifically, for the steps, the hexagons are split in a mode of connecting the vertexes to form a polygonal random combination; connecting the first and third vertexes, and dividing the hexagon into a pentagon and a triangle; connecting the first vertex with the fourth vertex, and dividing the hexagon into two quadrilaterals; the first vertex and the third vertex are respectively connected, and the fourth vertex and the sixth vertex divide the hexagon into two triangles, namely a quadrangle; according to the light distribution requirement, designating a direction as the normal direction of a plane, selecting any point of the polygon to pass through the plane, and projecting all the rest vertexes of the polygon to the plane, so that single polygon vertexes are coplanar; and changing any side of all polygons into curves to form polygon-like random combinations.
Or, in the step S4, encrypting the point array according to any one of two directions, and inserting a point into each two vertexes; converting the original 2x2 lattice into a 2x3 lattice, and sequentially connecting the newly inserted point and two vertexes of the original quadrangle to form a triangle; according to the light distribution requirement, designating a direction as the normal direction of the triangle, selecting any point of the triangle to pass through the plane, and projecting the other two vertexes of the triangle onto the plane; any side of all triangles is changed into a curve to form a triangle-like shape.

Step b, as shown in fig. 2, defines discrete points in two directions within the enclosed area, which may be located on the boundary of the enclosed area. The number of discrete points can be determined as desired. The denser the discrete points are, the more polygons of the formed light distribution pattern of the car lamp are. Two adjacent points are sequentially connected in two directions, so that a plurality of quadrilateral small unit areas can be formed, each two adjacent small unit areas share one side, and each four small units share an apex, as shown in fig. 3.
