The LED lens belong to collimation more and focus on type lens in the market, and are not suitable for many actual instructions for uses, cause problems such as light pollution and illuminating effect be not good easily.This just requires when design LED light fixture optical system components, should use scene to require to carry out the luminous intensity distribution design according to reality.
In sum, to the defective of prior art, need a kind of polarization type light-distribution lens especially to solve the above-mentioned problem of mentioning.
Summary of the invention
The purpose of this invention is to provide a kind of polarizing lens, when reaching illuminating effect, do not produce light pollution, and improve the light source utilization rate and actual accomplish energy-conservation.
The technical problem that the present invention solved can adopt following technical scheme to realize:
A kind of LED light fixture is used polarizing lens; Comprise a lens body, it is characterized in that the bottom surface of said lens body is provided with optical input; The end face of lens body is provided with the light delivery outlet, and the cambered surface of lens body both sides is set to first reflecting surface and second reflecting surface respectively; Said optical input, the light delivery outlet and first reflecting surface and second reflecting surface all adopt unsymmetric structure, and optical input is a groove structure, and the both sides sidewall of groove forms optical input surface, and the light delivery outlet connects two oblique line structures for the evagination circular arc.
In one embodiment of the invention, said groove is asymmetrical three oblique line segment structures, and the angle of both sides sidewall and bottom surface is respectively 137 degree and 117 degree.
In one embodiment of the invention, said first reflecting surface and second reflecting surface are asymmetric camber line structure, and the first reflecting surface camber line slope range is that 0.6~1.1, the second reflecting surface camber line slope range is 0.58~1.33.
In one embodiment of the invention, said output face connects two oblique line structures for the evagination circular arc, and left and right sides oblique line angle is respectively 37 degree and 27 degree.
In one embodiment of the invention, said lens body bottom is provided with two preceding formula locating holes that run through body, a back of the body formula locating hole, a balance boss and two legs; Formula locating hole and two legs all are symmetrically distributed about the balance boss before said two; Said lens body is affixed through preceding formula locating hole and aluminium base, or affixed through back of the body formula locating hole and aluminium base.
In one embodiment of the invention, said lens body adopts the optical-grade transparent PC material.
The invention has the beneficial effects as follows that the light that led light source is sent carries out the control of polarized light type secondary light-distribution, effectively control problems such as light pollution that background technology exists and illuminating effect be not good, effectively improve the led light source utilization rate.
