Abstract
The utility model discloses a kind of LED lens, the LED lens include base, astigmatism part, reflecting part.The base of the lens has two locating dowels, and the outer surface C0 C180 sections of the lens astigmatism part are semicircle or elliptical shape, and C90 C270 sections are semicircle or elliptical shape；The astigmatism portion inner surface C0 C180 sections of the lens are elliptical shape, and C90 C270 sections are semi-circular shape, and inner surface has vertical reflecting surface；There is cavity between the inner lens surfaces and base；The utility model realizes that High-Pole Lamp is downward or function of upward polarisation on illumination functions, can be by place near lamp stand and uniform illumination farther out, and reduce the total reflection of lens surface and reflex back and forth, more light are disposably transmitted, be conducive to improving the utilization rate of light, and be easy to volume production.
Description
Technical field
The present invention relates to field of LED illumination, a kind of LED lens are especially designed.
Background technology
LED is a kind of economizing type energy being widely known by the people, and purposes is in extensive range, and LED is easily achieved various forms of luminous intensity distributions,
The lens of different distribution curve fluxs are designed as needed.Current luminous intensity distribution mainly has two kinds, and one kind is once light-distribution, and this luminous intensity distribution is straight
Tipping is fitted in LED encapsulation, the luminous intensity distribution of street lamp batswing tab shape is used primarily at present, once light-distribution is because of technologies such as LED encapsulation
Limitation, it is difficult to realize the polarisation to side larger angle, another is secondary light-distribution, and secondary light-distribution is easily achieved various forms of
Luminous intensity distribution, but easily there is the phenomenon of total reflection that light occurs in refracting process and some light roundtrip in secondary light-distribution,
Light transmittance declines substantially, causes the serious waste of light.
The content of the invention
To solve above-mentioned technical problem, the invention provides a kind of LED lens, including：Base, astigmatism part, reflection
Part, realizes wide-angle polarisation in illumination, and effectively reduces the optical energy loss that total reflection and multiple reflections are caused, and is conducive to
Improve the efficiency of light energy utilization.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of LED lens, including：Base, astigmatism part, reflecting part.The C0-C180 sections of the lens scatter part
Outer surface is semicircle or elliptical shape, and C90-C270 sections are semicircle or elliptical shape；The astigmatism portion inner surface of the lens
C0-C180 sections be both sides be rectilinear form in the middle of circular arc, C90-C270 sections are semi-circular shape or elliptical shape；It is described
Astigmatism portion inner surface and reflecting part surface composition inner chamber, the inner chamber be located at lens side.
Further, the reflecting surface of described reflecting part is perpendicular to base.
Further, described base has locating dowel.
Further, the inner chamber is located at scattered portion side.
Compared with prior art, such scheme has advantages below：
, wide-angle polarisation can be realized on illumination functions at first point, can realize that higher lamp stand is immediated vicinity apart from lamp stand
Illumination uniformity, brightness gets a promotion；Second point can reduce the generation of total reflection so that more light are disposably projected,
Improve the efficiency of light energy utilization；Thirdly, it is more easy to realize in surface configuration of the structure without complexity, production.

Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The present invention is described with reference to schematic diagram, when present example is described in detail, for purposes of illustration only, device junction composition can not
According to general ratio local scale, and say that defeated schematic diagram is example, it should not be limited the scope of the invention herein.This
Outside, the three-dimensional space of length, width and height should be included in actual fabrication.
It is a kind of LED lens arrangements schematic diagram provided by the present invention with reference to Fig. 1-6, Fig. 1；It can be seen that institute
A kind of LED lens stated include：In base 1, the locating dowel 3 of scattered portion 2, scattered portion inner surface 4, vertical reflecting surface 5, lens
Chamber 6, scattered portion outer surface 7.
Described base 1 has two locating dowels 3, and locating dowel 3 is used for positioning the position of lens, prevents lens in production and application
During occur the phenomenon such as loosening, come off.
The C0-C180 sections of the described outer surface 7 of scattered portion 2 are semicircle or elliptical shape, and C90-C270 sections are half
Circle or elliptical shape；The C0-C180 sections of the inner surface 4 of the astigmatism part 2 of the lens be both sides be straight line in the middle of circular arc
Shape, C90-C270 sections are semi-circular shape or elliptical shape.
Space of the described lens inner chamber 6 between described astigmatism portion inner surface 4, vertical reflecting surface 5 is constituted.
Referring to figs. 2 and 3 described lens inner chamber 6 is located at the side of scattered portion 4.
With reference to a kind of light schematic diagrames in the C90-C270 sections of LED lens of Fig. 6, lead to from signal it can be seen from the figure that light
Cross after astigmatism portion inner surface 4, scattered portion outer surface 7 are reflected and project, light deviation C270 sides, vertical reflecting surface 5 it is anti-
Penetrate after light astigmatism portion inner surface 4, scattered portion outer surface 7 are reflected and project, light deviation C270 sides；I.e. light can be inclined to one
Side.
The present invention gain be：Wide-angle polarisation can be realized on illumination functions, can realize higher lamp stand apart from lamp stand very
Local illumination uniformity closely, brightness get a promotion；The generation of total reflection can be reduced so that more light are disposably penetrated
Go out, improve the efficiency of light energy utilization；It is more easy to realize in surface configuration of the structure without complexity, production.
The preferred scheme simply invented in above-described embodiment, this real invention can also have other embodiments.The skill of this area
Art personnel can also make equivalent variations or replacement on the premise of without prejudice to spirit of the invention, and these equivalent variations or replacement are wrapped
