The problem of there is macula lutea.
Therefore, regarding to the issue above, it is necessary to propose further solution.
Utility model content
The purpose of this utility model is to provide a kind of LED street lamp lens, to overcome the deficiencies in the prior art.
To realize above-mentioned utility model purpose, the utility model provides a kind of LED street lamp lens, and it includes：Base, light extraction
Face, incidence surface；
The exiting surface is located in the one side of the base with protruding out, and the exiting surface is curved surface, the incidence surface depression
Ground is located on the another side of the base, and the incidence surface is curved surface, and the surface of curved surface incidence surface has some pearl faces, if described
Dry pearl face is uniformly distributed in the surface of the curved surface incidence surface, and the side in edge other the pearl faces adjacent with surrounding in any pearl face
Edge keeps connecting.
As the improvement of LED street lamp lens of the present utility model, the pearl face is arranged at the curved surface incidence surface with protruding out
Surface on.
As the improvement of LED street lamp lens of the present utility model, the pearl face is circle.
As the improvement of LED street lamp lens of the present utility model, there is hollow hemispherical on the another side of the base
Space, the incidence surface is located at the bottom of the hemispherical space.
As the improvement of LED street lamp lens of the present utility model, the LED street lamp lens also include positioning component, described
Positioning component is arranged on the another side of the base.
As the improvement of LED street lamp lens of the present utility model, the positioning component includes the fixed pin of the first positioning and the
The fixed pin of two positioning, the fixed pin of the first positioning and the fixed pin of the second positioning are vertically disposed at the another side of the base
On.
Compared with prior art, the beneficial effects of the utility model are：LED street lamp lens of the present utility model use curved surface
Incidence surface and exiting surface, and in some equally distributed pearl face structures of surface layout of curved surface incidence surface, thus, overcoming
The light that LED is sent is after lens, hot spot skewness, the problem of easily macula lutea occur.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments described in the utility model, for those of ordinary skill in the art, is not paying creative work
On the premise of, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the front view of the embodiment of LED street lamp lens one of the present utility model；
Fig. 2 is the schematic perspective view of LED street lamp lens in Fig. 1, and the visual angle of the schematic perspective view is saturating from the LED street lamp
Mirror bottom and the visual angle of about 45 ° of inclination.
Embodiment
The utility model is described in detail shown each embodiment below in conjunction with the accompanying drawings, but it should explanation,
These embodiments are not limitation of the utility model, and those of ordinary skill in the art are according to these embodiment institute works
Energy, method or equivalent transformation or replacement in structure, are belonged within protection domain of the present utility model.
As shown in Figure 1, 2, LED street lamp lens of the present utility model include：Base 10, exiting surface 20, incidence surface 30, positioning
Component（It is not shown）.
The base 10 is used to carry the exiting surface 20 and incidence surface 30.Specifically, the exiting surface 20 protrudes out status
In in the one side of the base, the exiting surface 20 is curved surface, and curved surface exiting surface 20 is the smooth arcwall face in surface.
The incidence surface 30 is hollowly on the another side of the base, and the incidence surface 30 is curved surface.In order to realize
There is hollow hemispherical space 11, the incidence surface 30 is located at the hemisphere on above-mentioned purpose, the another side of the base 10
The bottom in shape space 11.Meanwhile, it is arranged such, incident light is radiated at the incidence surface from the hollow porch of hemispherical space 11
On 30, be conducive to the aggregation of incident light, it is to avoid the scattering of incident light.
Further, in order to overcome hot spot skewness, the problem of easily macula lutea occur, the surface of curved surface incidence surface 30 has
There are some pearl faces 31, some pearl faces 31 are uniformly distributed in the surface of the curved surface incidence surface 30, and the side in any pearl face 31
The edge in edge other the pearl faces adjacent with surrounding keeps connecting.So as to which some pearl faces 31 keep dense arrangement, and show honeycomb greatly
Shape is arranged in the surface of the curved surface incidence surface 30.Preferably, the pearl face 31 is arranged at the curved surface incidence surface 30 with protruding out
Surface on, and the pearl face 31 for circle.
The positioning component is used to realize that the installation of LED street lamp lens of the present utility model is fixed.Specifically, the positioning
Component is arranged on the another side of the base 10.The positioning component includes the fixed pin of the first positioning and the second positioning is fixed
Pin, the fixed pin of the first positioning and the fixed pin of the second positioning are vertically disposed on the another side of the base 10.So as to lead to
The location and installation of LED street lamp lens of the present utility model can be realized by crossing the fixed pin of the first positioning and the fixed pin of the second positioning.
In summary, LED street lamp lens of the present utility model use the incidence surface and exiting surface of curved surface, and enter light in curved surface
Some equally distributed pearl face structures of surface layout in face, thus, light that LED sends is overcome after lens, hot spot point
Cloth is uneven, the problem of easily macula lutea occur.
