Abstract
The invention aims at providing an automobile headlamp optical system using a lens for achieving passing light. Light beams emitted by a light source are reflected by an ellipsoid reflection bowl with the surface plated with aluminum into near parallel light beams, part of light of the parallel light beams is blocked by a metal baffle, the edge of the top end of the metal baffle is made to be in the shape of a light and shade cut-off line, and accordingly the passing light shape regulated by laws and regulations is formed. The light beams are finally refracted by the lens with the outer surface provided with a periodical microstructure array, the microstructure array can change the incidence angle of emitted light of the lens, and therefore the light beams originally emitted in the specific direction are scattered. The microstructure array is distributed in a concave-convex continuous structure, all sections of the concave-convex fluctuant slope surface are machined to be with inconsistent curvature radii, and therefore the emergence angle of each light beam is also changed, the light beams are better scattered, and especially in the light and shade cut-off line part, the original sharp cut-off line becomes smooth.
Description
Technical field
Design vehicle headlamp field of the present invention, the vehicle front lighting lamp optical of dipped beam realized by more particularly, to a kind of use lens
System.
Background technology
No matter in which country car headlamp regulation, for dipped beam, there is clear and definite "cut-off"line regulation.Cut
Only the setting of line can allow driver preferably observe road conditions in the outside of direction of traffic, i.e. in the inner side of direction of traffic (simultaneously
Opposite meeting side) reduce irradiation to opposite drivers and pedestrians, thus protecting pedestrian on the driving safety of opposite car and road
Safety."cut-off"line be car light irradiation to clear zone and the dark space not being irradiated to (or being seldom irradiated to) between boundary
Line.Smooth "cut-off"line can provide driver more preferably driving comfort.Excessively sharp keen dead line can attract driver's mistake
Many attention, are especially accelerating, brake, or the road surface jolted are it will be apparent that dead line is rocking the attention that driver can be attracted excessive
Power, ultimately causes the driving fatigue of driver.Excessively smooth dead line may reach fuzzy degree simultaneously, leads in dark space
Some regions illumination can exceed the numerical value of rules and regulations, most serious may result in double "cut-off"lines.The clear journey of dead line
Degree to be weighed by gradient, especially in ece regulation, Grad is clearly required, is between 0.13-0.4.With lens
Dipped beam optical system in, the gradient of "cut-off"line effectively can be regulated and controled by lens.German docter optics company is in glass
Glass lens outer surface carries out frostization and processes so that being dissipated from the light beam of lens outer surface outgoing, largely improves light and shade
The smoothness of dead line, reduces dead line to the annoyance level during driver driving while meeting regulation.In lens
Outer surface carry out frostization process most of adopt sandblasting or emery wheel grinding, this technique is more suitable for glass lens, to plastic lens
Difficulty of processing very big.This technique often forms micro structure in irregular shape simultaneously, and the size of micro structure is also difficult to accurately
Control, thus leading to the regulation and control difficult to reach expected effect of dead line readability it is often more important that cannot pass through in early stage
Simulation calculates the impact that the process of assessment lens surface brings to dead line.
Content of the invention
For solving the above problems, the present invention provides a kind of use lens to realize the vehicle front lighting lamp optical system of dipped beam, light
The ellipsoid reverberation bowl that the light beam that source sends is aluminized by surface is reflected into nearly collimated light beam, and collimated light beam is blocked one by metal baffle
Light splitting, the tip edge of metal baffle is made into the shape of "cut-off"line, thus forming the dipped beam light type of rules and regulations, light beam
There is the refraction of periodic micro structure array lens finally by outer surface, micro structure array can change entering of lens emergent light
Firing angle, so that originally being dissipated towards the light beam of specific direction outgoing, micro structure array is distributed as concavo-convex continuous structure, recessed
The radius of curvature of domatic each section of raised volt is processed into inconsistent, thus the angle of emergence of each light beam is also varied so that
Light beam is preferably dissipated, and especially, being embodied in "cut-off"line part is so that originally sharp keen dead line becomes smooth.
It is an object of the invention to provide the vehicle front lighting lamp optical system of dipped beam realized by a kind of use lens, include ellipsoid
Reverberation bowl, middle on the left of described ellipsoid reverberation bowl is the first focal position, is provided with light source at the first focal position；Described ellipsoid
In reverberation bowl, lower right side is provided with metal baffle, metal baffle tip edge be "cut-off"line shape and tip height with
Light source center point is highly concordant；It is provided with lens on the right side of described ellipsoid reverberation bowl, is outer surface on the right side of lens, lens outer surface has
Periodically micro structure array；Described micro structure array is the continuous structure of concavo-convex fluctuating, the continuous structure of concavo-convex fluctuating every
Individual depression and projection are grade in length and width size, height dimension are micron order.
Further improvement is that: described lens are convex lenss.
Further improvement is that: the continuous structure of concavo-convex fluctuating of described micro structure array all of domatic have differ
The radius of curvature causing.
Further improvement is that: described ellipsoid reverberation bowl surface is coated with aluminum.
Beneficial effects of the present invention: the ellipsoid reverberation bowl that the light beam that light source of the present invention sends is aluminized by surface is reflected into closely flat
Row light beam, collimated light beam is blocked a part of light by metal baffle, and the tip edge of metal baffle is made into the shape of "cut-off"line
Shape, thus forming the dipped beam light type of rules and regulations, light beam has the lens of periodic micro structure array finally by outer surface
Refraction, micro structure array can change the angle of incidence of lens emergent light, so that originally towards the light beam quilt of specific direction outgoing
Dissipate, micro structure array is distributed as concavo-convex continuous structure, ups and downs domatic each section of radius of curvature is processed into not
Unanimously, thus the angle of emergence of each light beam is also varied so that light beam is preferably dissipated, especially, it is embodied in light and shade cut-off
Line part is so that originally sharp keen dead line becomes smooth.
