Description
Technical field
The utility model is related to automobile lamp technical field more particularly to a kind of lens for car light, a kind of using should
The car headlamp of lens and a kind of automobile including the headlamp.
Background technology
Common projection-type lighting system in automobile lamp generally all includes light source, speculum, barn door and lens.
Speculum is elliposoidal, and the centre of luminescence of light source is arranged at the perifocus of ellipsoidal shaped mirror, and the light that light source is sent out passes through
It is converged near the over focus of ellipsoidal shaped mirror after ellipsoidal shaped mirror reflection, barn door is set to the remote of ellipsoidal shaped mirror
Focal point, shape is consistent with the "cut-off"line shape required by dipped beam, and "cut-off"line is carried finally by lens forming
Class directional light lower beam illumination light shape.The characteristics of car headlamp be the light that sends out of light source by lens inside minute surface outward
Minute surface projects, and minute surface on the inside of directive after incident ray focuses near lens focus, it is close to horizontal direction to project light.Cause
This, vehicle lamp lens only consider horizontal parallel light or the focusing close to horizontal direction light, and sunlight directive lens are general
By top directive lens obliquely, and angle constantly changes.
As shown in Figure 1, it is plane that traditional lens, which use planoconvex spotlight, inside minute surface, it is arranged towards light source, outside mirror
Face is aspherical, and the light of light source after the focusing of planoconvex spotlight near focal point by the inside minute surface of planoconvex spotlight, penetrate outward by minute surface
Go out, it is close to horizontal direction to project light.Traditional planoconvex spotlight material is transparent plastic or glass, such as PC
(Polycarbonate, makrolon), PMMA (Polymethyl Methacrylate, polymethyl methacrylate) etc..Root
According to its diameter and focal length, maximum gauge, which is 20 millimeters to 50 millimeters, to be differed, and being advantageous in that for this lens passes through
Aspherical convex lens design, the existing Aberration Problem of correction spherical convex lens imaging, makes lens imaging be more clear, undistorted.
But also bring solar irradiation on daytime is mapped to lens to this lens simultaneously, is focused in lens front after reflection from lens, and
It is converged after lens reflect, the problem of speculum rear portion focuses, burns part in lamp.And with angle of incidence of sunlight degree
Difference, focal position are in dynamic change in a certain range.As shown in Figure 2, Figure 3 and Figure 4, respectively from the horizontal by 30 °,
The focusing simulation of minute surface on the outside of the parallel rays directive planoconvex spotlight at 45 ° and 60 ° angles.Wherein, Fig. 2 show from the horizontal by
The side of the parallel rays at 30 ° of angles minute surface on the inside of planoconvex spotlight after planoconvex spotlight forms inner focusing;Fig. 3 is shown and level
The side of parallel rays minute surface on the inside of planoconvex spotlight after planoconvex spotlight at direction angle at 45 ° forms inner focusing, through inside
Then the side of minute surface forms exterior focusing to light after mirror-reflection on the outside of planoconvex spotlight;Fig. 4 is shown from the horizontal by 60 ° of angles
Parallel rays pass through planoconvex spotlight when, be largely irradiated to inside minute surface when incidence angle be more than the angle of total reflection, formed total reflection,
The side of minute surface forms the exterior focusing of stronger luminous energy on the outside of planoconvex spotlight.
The patent of publication number CN 101298906A discloses a kind of car headlamp based on biconvex lens, utilizes inside
Minute surface is spherical surface, the biconvex lens design scheme that outside minute surface is free form surface, reduces reflection and focuses focal length, reduces the sun
Light focuses the risk for burning other parts on car light or automobile after reflection from lens.As shown in figure 5, sunlight L3 is with certain angle
The directional light of degree is incident, and after the reflection of biconvex lens 4, reflected light L1 is focused near at A, after the reflection of planoconvex spotlight 6, reflection
Light L2 is focused near B, it can be seen that the focus position through biconvex lens reflection is less than the focus point reflected through planoconvex spotlight
Position.But there are still following several disadvantages for this design scheme:
(1) biconvex lens is only capable of reducing the focal length after sun light reflection, reduces sunlight and focuses burning after reflection from lens
The risk of other parts on car light or automobile is ruined, the problem of being focused after reflecting can not be completely eliminated.
(2) biconvex lens cannot solve to burn in the side formation inner focusing in interior side mirror face after sunlight penetrates lens
On the inside of mirror the problem of parts.
(2) biconvex lens is due to its light path principle, and size is still partially thick, and materials are more, causes of high cost, and quality is big etc.
Defect, the resistance to shock being unfavorable in driving conditions, also, light path of the light in lens is larger, causes light in lens
The luminous energy absorbed by lens when portion propagates is more, reduces the light efficiency of projection-type lighting system.
