Description
Technical field
The present invention relates to lighting apparatus, bar lamp lens are exempted from specifically a kind of glare prevention LED low latitude.
Background technique
LED exempt from bar lamp due to its high photosynthetic efficiency, low-power consumption, uniform illumination, without light pollution, be applied to gradually bridge, tunnel,
The Landscape Lightings such as road place.In the prior art, LED exempts from bar lamp and generally uses reflector mode, and centre is arranged high-power COB light
Source, requirement of this mode to radiator is high, radiator is bulky, unsightly, installation and maintenance it is inconvenient, therefore, using saturating
The mode of mirror light distribution is also applied gradually, but often due to LED lamp bead discrete quantities used are more, dazzle grade can not meet respectively
The requirement of kind application.
After lens, a part of light is directly directly projected from the paraboloid of lens the light that light source issues, and influences hot spot
Uniformity, while veiling glare increase dazzle；Light, since lens surface is plane, looks around lamp in different directions after lens
Tool, marginal portion still have more light that can enter human eye, and dazzle is more serious.
Summary of the invention
The purpose of the present invention is in view of the deficiencies of the prior art, and a kind of glare prevention LED low latitude is provided and exempts from bar lamp lens.This
Kind of lens are at low cost, it is easy to process, Facing Movement dazzle can be weakened, improve the light efficiency that bar lamp is exempted from the low latitude LED, driven for driver safety
It sails and provides safeguard.
Realizing the technical solution of the object of the invention is:
Bar lamp lens are exempted from a kind of glare prevention LED low latitude, unlike the prior art, including lens mounting base, the lens peace
The bottom surface for filling seat is equipped with LED lamp bead chamber, and the another side of lens mounting base is equipped with the lens light guide of polarisation list batwing structure, thoroughly
Mirror leaded light physical efficiency the cover lives LED lamp bead chamber, and wherein one side of lens light guide is cut away, cut surface and lens mounting base plane
Vertically, reflective membrane is covered on the cut surface.
The lens light guide is two-way polarisation light guide.
The cut surface lens mounting base parallel with intersecting lens in lens mounting base with lens mounting base intersecting lens
Central axes distance be 1.8-2.2mm.
The lens mounting base is equipped with seal groove, it can be achieved that encapsulating waterproof in the periphery of LED lamp bead chamber.
The lens mounting base is equipped with one group of lens positioning protrusion in face where LED lamp bead chamber.
The lens mounting base is equipped with one group of lens mounting hole.
One of the lens light guide equipped with polarisation list batwing structure is towards road surface when the lens mounting base is fixedly mounted
Inclination, the angle between lens mounting base and road surface is 35 ° -55 ° and spends, and the cut surface face direction of traffic of lens light guide,
The light for issuing lamps and lanterns is strong up and weak down to be projected to the right front of lamps and lanterns, at once vehicle direction of advance, road while reaching anti-dazzle
Face brightness is also more uniform, more preferably meets road occupation requirement, makes the safer traveling of driver.
This lens are mounted on the light source board of corresponding every LED illuminating part, and the reflective membrane face of lens light guide is driven a vehicle
Direction, lens light guide have two-way polarizing function, it can be achieved that the two-way polarisation of X, Y, backwards to light through reflective membrane be reflected back it is positive from
And reach the application effect of the complete free from glare of direction of traffic.
This lens are directional light distribution lens, and the floodlight for issuing luminescent screen is saturating using the technical program after lens light distribution
After mirror is attached on lamps and lanterns, lamps and lanterns hot spot can be projected by the light conducting direction of lens design, be reflected back forward direction through reflective membrane backwards to light, mentioned
High whole light effect；Because after reflective membrane reflects, going out backwards to without strong light emission, to achieve the effect that put dazzle completely backwards to light.
This lens are at low cost, it is easy to process, Facing Movement dazzle can be weakened, improve the light efficiency that bar lamp is exempted from the low latitude LED, be
Driver safety driving provides safeguard.
