Abstract
A kind of automotive lighting lens arrangement, by light transmission part（1）With installation section（2）Composition, light transmission part（1）With installation section（2）Form lens, light transmission part（1）Using non-spherical lens as lens, it is characterised in that：The light transmission part（1）Outer surface edge position be equipped with one circle dermatoglyph（3）, light is through dermatoglyph（3）Scattering with refraction change projecting direction；Light transmission part（1）Except dermatoglyph（3）Region in addition is uniformly distributed dotted decorative pattern（4）, light is through sparrow pecked（4）It is homogenized.The present invention, the scattering and refraction of light are carried out by the dermatoglyph of light transmission part, meet requirement of the standard to dipped beam light shape and each light distribution test point illumination, distance light light is homogenized by the sparrow pecked on light transmission part, it prevents among light that excessively bright border is excessively dark, substantially increases the safety of driving.
Description
Technical field
The present invention relates to a kind of automobile lamp technical fields, and in particular to a kind of automotive lighting lens arrangement.
Background technology
Headlamp is the lamps and lanterns that automobile illuminates road ahead in night running, its light distribution design is to influence lighting quality
With the key factor of effect.Projection optical unit is applied on car headlamp and is increasingly popularized, this is because projection optics list
Member can not only bring high-grade sense and it to have high light-gathering, good horizontal development width to entire headlamp, also more attractive.It throws
Optics list is penetrated mainly by light source, speculum, barn door and convex lens group at the projection optical unit of existing distance-light one exists
Electromagnetic valve structure is increased on barn door, for realizing the switching of distance-light.According to the difference of automobile type configuration, difference can be selected
The projection optical unit of light source, but whether being configured using which kind of, it is necessary to meet in ECE or GB standards to distance-light shape
The numerical requirements of regulation and each light distribution test point；GB requires the dark space above dipped beam dead line to have light with ECE standards in recent years
According to 5.7.4.3 require regulation in automobile lamp regulation GB4599-2007：Test point P1+P2+P3≤0.3lx, P4+P5
+P6≧0.6lx、0.7lx≧ P7≧0.1lx、0.7lx≧ P8≧0.2lx.When lens group is in low-beam function, due to the use of
Barn door is used as the effect of blocking, level to be all occluded by line and 15 degree of light above line, and luminous energy is almost nil,
Since the imaging of convex lens is to stand upside down, it means that have to that convex lens is enable to receive the light below focus；
When lens group is in road function, due to the focusing function of lens, the illumination of light beam is relatively concentrated, and rim ray is dark, night
Field-of-view angle is small when driving be easy to cause that the vehicle Driver Vision range is wide, safety problem etc. caused by eyes fatiguability.
Invention content
Pass through light transmission part present invention aims at a kind of automotive lighting lens arrangement is provided for disadvantage mentioned above
Dermatoglyph carries out the scattering and refraction of light, meets requirement of the standard to dipped beam light shape and each light distribution test point illumination, passes through light transmission
Sparrow pecked on part homogenizes distance light light, prevents excessively bright border among light excessively dark.
The technical solution of the technology of the present invention is achieved in the following ways：A kind of automotive lighting lens arrangement, by saturating
Light part is formed with installation section, and light transmission part forms lens with installation section, and light transmission part is using non-spherical lens as light distribution
Mirror, it is characterised in that：The outer surface edge position of the light transmission part be equipped with one circle dermatoglyph, light through dermatoglyph scattering with
Refraction changes projecting direction；Region of the light transmission part in addition to dermatoglyph is evenly distributed with sparrow pecked, and light penetrates sparrow pecked
It is homogenized.
The cyclic annular refractive power unit that the dermatoglyph area is looped around by one group around light transmission part forms, and skin is reached through speculum
Light on line is scattered and is reflected by cyclic annular refractive power unit, projects each survey as defined in automobile short-distance testing standard
Pilot forms the light shape for meeting standard requirement.
The light transmission part is placed on the primary optical axis of projection optical unit.
Region of the light transmission part in addition to dermatoglyph, which is equipped with sparrow pecked, fish point decorative pattern, well word decorative pattern etc., point
For shape decorative pattern also alternatively at the lines circular fringes of stacking, the spacing between lines circular fringes is uniform.
Structure of the invention, when low-beam function, speculum reflects the scattering that light carries out light by the dermatoglyph of light transmission part
With refraction, meet requirement of the standard to dipped beam light shape and each light distribution test point illumination；When road function, speculum reflecting light
Line homogenizes distance light light by the sparrow pecked on light transmission part, prevents excessively bright border among light excessively dark, significantly
Improve the safety of driving.
Description of the drawings
Fig. 1 is the structural schematic diagram of the new shape of this practicality.
Fig. 2 is the structural schematic diagram using lines circular fringes.
In figure：1 light transmission part, 2 installation sections, 3 dermatoglyphs, 4 sparrow peckeds, 5 lines circular fringes.
Specific implementation mode
Known by Fig. 1, Fig. 2, a kind of automotive lighting lens arrangement is made of, transmittance section light transmission part 1 and installation section 2
1 is divided to form lens with installation section 2, using non-spherical lens as lens, light transmission part 1 is placed in projection optics for light transmission part 1
On the primary optical axis of unit.The outer surface edge position of the light transmission part 1 is equipped with a circle dermatoglyph 3, and light is dissipated through dermatoglyph 3
It penetrates and changes projecting direction with refraction；Region of the light transmission part 1 in addition to dermatoglyph 3 is uniformly distributed dotted decorative pattern 4, and light is through dotted
Decorative pattern 4 is homogenized.Region of the light transmission part 1 in addition to dermatoglyph 3, which is equipped with sparrow pecked 4, fish point decorative pattern, well word decorative pattern
Deng, sparrow pecked 4 also alternatively at the lines circular fringes 5 of stacking, the spacing on 5 shape of lines ring between striped is equal, around here
Away from the spacing between the striped in orthographic projection plane.Structure of the invention, when low-beam function, speculum reflect light pass through it is saturating
The dermatoglyph 3 of light part 1 carries out the scattering and refraction of light, meets standard and is wanted to dipped beam light shape and each light distribution test point illumination
It asks；When road function, speculum reflects light and is homogenized to distance light light by the sparrow pecked 4 on light transmission part 1,
It prevents among light that excessively bright border is excessively dark, substantially increases the safety of driving.
