Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can To be combined with each other.
The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiment.
The present invention provides a kind of lens, the lens 100 include main part 110, and the main part 110 includes the first light Face 111 and the second optical surface 112 are formed with linear type focus line 113, first optics on first optical surface 111 The height in face 111 is gradually decreased from the focus line 113 to two sides, and second optical surface 112 includes multiple arranged in parallel Fin 114, the fin 114 extend perpendicularly to the focus line 113, and the fin 114 has arc-shaped convex surface.
As shown in figure 4, focus line 113 is the highest on the first optical surface 111, and the height of two sides is gradually lowered, For the convex surface of deformation;As shown in Figure 3 and Figure 5, the arc-shaped convex surface of fin 114 can be considered as the portion perimeter face of cylindrical structure, The extending direction of fin 114 is parallel to the central axial direction of such cylindrical structure.
By lens 100 be applied to car light when, lens 100 can put for:Focus line 113 can prolong generally in a horizontal direction It stretches, and fin 114 extends along the vertical direction, light source can be placed on first this side of optical surface 111, the first optical surface 111 It can be used as the plane of incidence, the second optical surface 112 can be used as exit facet, and the first optical surface 111 can make incident light vertical It is converged on direction to intermediate focus line 113, the second optical surface 112 can make incident light formation spread in the horizontal direction Emergent light.That is, the light beam that light source can be made to generate is vertical by the first optical surface 11 and the second optical surface 112 Converge on direction, and spread in the horizontal direction, more suitable for car light horizontal irradiation range it is relatively large, irradiate model vertically Enclose relatively small characteristic.
In addition, being seamlessly transitted between the adjacent fin 114 by arc-shaped concave 115.As shown in figure 3, fin 114 It itself is formed with arc-shaped convex surface, can be connected by arc-shaped concave 115 between two adjacent arc-shaped convex surfaces, is realized flat It slips over and crosses, that is to say, that the arc-shaped convex surface is overlapped with tangent line of the arc-shaped concave at tie point.Wherein, arc-shaped recessed The central axis in face 115 can be parallel to the central axis on arc-shaped convex surface, and particularly, the diameter of arc-shaped concave 115 is far small Diameter in arc-shaped convex surface, that is, the main part of the second optical surface 112 is arc-shaped convex surface, is realized by arc-shaped convex surface The diffusion of light in the horizontal direction, and arc-shaped concave 115 is only to be smoothly connected two arc-shaped convex surfaces, area accounting It can be ignored, optical effect also can be ignored.
Further, the radius on the arc-shaped convex surface of the fin 114 is identical, the equidistantly arrangement of fin 114.It is multiple The optical property of fin 114 is consistent, in addition, since the second optical surface 112 is equipped with multiple fins 114, it is described arc-shaped The radius on convex surface is compared to the second optical surface 112 size in the horizontal direction comparatively very little, so that the second optical surface 112 The diffusion light of formation everywhere in a lateral direction is more uniform.
Specifically, 113 two sides of focus line are respectively formed two sub- optical surfaces, the sub-light face includes multiple protrusions Arc surface, the centerline axis parallel of each arc surface is in the focus line 113.The arc surface can be considered as central axis Line is parallel to the portion perimeter face of the cylinder of focus line 113, i.e., cylindrical arc surface (the arc-shaped convex surface phase with fin 114 Like), the first optical surface 111 is formed as the plane of incidence of intermediate protrusion (protrusion of focus line 113), so as to erect incident beam Histogram is converged upwards.
Particularly, in each sub- optical surface, on the direction from the focus line 113 towards two sides, the circle The radius of cambered surface successively increases, and multiple arc surfaces are successively smoothly connected.By perifocus line 113 circular arc radius surface relatively Small, the circular arc radius surface far from focus line 113 is relatively large, so that the adjacent arc surface is allowed to be smoothly connected, i.e., it is adjacent Tangent line of two arc surfaces in junction coincide with one another.At focus line 113, two circles of two sub- optical surfaces Cambered surface is connected to each other, and focus line 113 is extreme higher position.
In addition, two sub- optical surfaces are symmetrical about the focus line 113.Two of the two sides of focus line 113 are symmetrical Sub- optical surface light gathering it is identical so that convergence formed light beam it is more uniform in the vertical direction, without apparent light and shade Area.Wherein, at focus line 113, the identical arc surface of two radiuses of two sub- optical surfaces is connected to each other, and to form angle bigger Arc surface, focus line 113 be the arc surface on highest bus.
In addition, the main part 110 includes the transition face 116 positioned at 113 both ends of focus line, the transition face 116 It is smoothly connected in two sub- optical surfaces.As shown in Figure 1 and Figure 4, the effect of transition face 116 is in the first optical surface 111 Both ends form smooth transition, avoid the occurrence of angular shape, protect main part 110.Transition face 116 can neglect the effect of light source Slightly or light source can be set to be aligned in focus line 113, so that the light issued is mainly incident on the first optical surface 111.
In addition, as depicted in figs. 1 and 2, the lens 100 further include consolidating around what the edge of the main part 110 was arranged Determine flange 120, is formed with through-hole on the fixed flange 120.Fixed flange 120 can be used for being auxiliarily fixed lens 100, avoid Relevant fixed structure is contacted with main part 110, influences the effect of main part 110.
Lens 100 can be made of various transparent, translucent materials, such as glass, polycarbonate, polymethyl methacrylate Deng.Preferably, the lens 100 are made of silica gel.The light transmittance of silica gel is relatively high, and has good heat resistance, When lens 100 and light source distance are smaller, 100 temperature of lens is relatively high, and thermal deformation resistant ability is more preferable, and silica-gel lens It is not easy to turn to be yellow.
In addition, the present invention provides a kind of luminescence components, wherein the luminescence component include light source portion, a lens with And secondary lens, the light that the light source portion generates pass sequentially through a lens and the secondary lens, wherein described primary Lens are lens 100 described in above scheme.The light that the light source portion generates can be incident in the first optical surface 111, and the Two optical surfaces 112 project, and then across secondary lens, secondary lens can be convex lens, converge to light.Wherein, burnt Dotted line 113 can horizontally extend in transverse direction, and fin 114 extends along the vertical direction, and the light that light source portion generates is passing through the It converges to focus line 113 when one optical surface 111, and is spread in the second optical surface 112 in transverse direction in the vertical direction, then Pass through the convergence of secondary lens 2 as convex lens.
The foregoing is merely better embodiments of the invention, are not intended to limit the invention, all of the invention Within spirit and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
