Specific embodiment
The contents of the present invention are further described with reference to the accompanying drawings of the specification.
As shown in Figs. 1-5, the processing method for present embodiments providing a kind of micro- striped of lens, includes the following steps:
S1, milling cutter is chosen, sets machined parameters；
S2, carry out striped processing in the outer surface of lens 1: milling cutter first along transverse direction feed, processes multiple mutual
Parallel travers 31 process multiple longitudinal stripes 32 being parallel to each other further along longitudinal direction feed；Or milling cutter is first
Feed in a longitudinal direction processes multiple longitudinal stripes 32 being parallel to each other and processes multiple further along transverse direction feed
The travers 31 being parallel to each other.
Wherein, in step S1, different milling cutter specifications can be selected according to actual needs, also can choose same milling
Knife specification selects different milling cutter step-lengths to carry out striped processing, and the micro- striped processed is different to optical influence degree.It is excellent
Selection of land, the milling cutter of selection are rose cutter, and the tip radius of spherical cutter is 0.5mm, and when processing, cutter head revolving speed is 30,000 turns every
Second.Machined parameters include streak height h and striped step pitch L.Micro- striped 3 in the present invention includes a plurality of Cross slat being parallel to each other
Line 31 and a plurality of longitudinal stripe 32 being parallel to each other.For the profile of the travers 31 shown in Fig. 5, travers 31
Streak height h is the difference in height between the highs and lows of travers 31, and the striped step pitch L of travers 31 is adjacent
Two travers 31 between the distance between minimum point.Same limit is also applied for longitudinal stripe 32.Preferably, item
Line height is 0.01-0.5mm, i.e. the streak height range of travers 31 and longitudinal stripe 32 is 0.01-0.5mm；It is preferred that
Ground, striped step pitch are 0.1-0.5mm, i.e., the step pitch between two adjacent travers 31 is 0.1-0.5mm, adjacent two
Step pitch between longitudinal stripe 32 is 0.1-0.5mm.
In step S2, travers 31 and longitudinal stripe 32 be it is multiple, travers 31 and extending direction and longitudinal direction
The extending direction of striped 32 is vertical.Wherein, travers 31 extend to the other side from the one side edge of outer surface 1 in transverse direction
Edge, longitudinal stripe 32 extend to neck one side edge from the one side edge of outer surface 1 along the longitudinal direction.In this way, lens are entirely outer
It is covered with latticed micro- striped on surface 1 completely.
It may not need after the completion of step S2 and the surface of lens be processed by shot blasting, or can be right before step S2
The surface of lens is processed by shot blasting, lens include outer surface 1 and inner surface 2, can be before step S2 to the outer surface of lens 1
It is processed by shot blasting with inner surface 2.The defining standard of outer surface 1 and inner surface 2 is: inner surface 2 is the entering light face of lens, outside
Surface 1 is the light-emitting surface of lens.
The lens with micro- striped can be prepared based on above-mentioned processing method, are provided on the outer surface 1 of lens netted
Micro- striped 3, micro- striped 3 is very small, and naked eyes are nearly imperceptible, and Fig. 3 and Fig. 4 are the effect for amplifying 50 times.Micro- striped 3 wraps
Travers 31 and longitudinal stripe 32 are included, travers 31 and longitudinal stripe 32 intersect vertically, travers 31 and longitudinal stripe
32 be it is a plurality of, a plurality of travers 31 are parallel to each other, and a plurality of travers 31 are in transverse direction from a side of outer surface 1
Edge extends to another side edge, and a plurality of longitudinal stripe 32 is parallel to each other, and a plurality of longitudinal stripe 32 is along the longitudinal direction from outer surface 1
One side edge extend to another side edge, so netted micro- striped 3 is covered with entire outer surface 1.The travers of micro- striped 3
31 and longitudinal stripe 32 be arc groove.
A kind of lens with micro- striated structure of the present embodiment can be used for the car light of automobile, and the illuminator in car light issues
Light, light first enters in lens through inner surface 2, then reflects through outer surface 1, due to being provided with micro- striped on outer surface 1
3, then light can change direction injection, or part through opposite slot after the groove face of travers 31 or longitudinal stripe 32 reflects
Change direction after the reflection of face to project, realizes the adjustment to radiation direction, the light uniformity of injection is more preferable, solves long-and-short distant light
Haves the defects that dark space with front fog lamp light type, but also the "cut-off"line of dipped beam is more clear.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode within the knowledge of a person skilled in the art can also be in the premise for not departing from spirit of the invention
Under make a variety of changes.
