Solidity；Luminous intensity distribution performance can meet ECE R113CLASS B class ECE R113CLASS C class ECE R113CLASS D classes ECE
R113CLASS E class GB25911-2010 and GB19152-2016 light distribution requirements, dipped beam "cut-off"line is clear, not dazzling.
The dipped beam LED lamp bead has 1-10 as a preferred technical solution, is respectively positioned under the low beam reflector
Side.
Several LED lamp bead quantity of the technical program are convenient for the distribution of position, make dipped beam power adjustable.
The lower rear of the mounting base is equipped with the heat dissipating housing being arranged upward as a preferred technical solution,.
The heat dissipating housing is integrated with the mounting base and is fabricated as a preferred technical solution,.
The heat dissipating housing of the technical program is used to give out LED lamp bead and irradiates the temperature sent out, reduces whole heat, and raising makes
Use the service life.
The front of the mounting base is equipped with mounting ring as a preferred technical solution, and dress is covered with outside the optical lens
Decorative circle, the rear portion of the case ring are connected and are bolted with the front of the mounting ring.This kind of structure makes optical lens
The connection of mirror and heat dissipating housing is more convenient and solid and reliable, improves stability in use.
The optical lens is semicircle as a preferred technical solution, and the outer rim of the optical lens is equipped with a circle and blocks
Fitting, the case ring are connected with shackle member clamping.
In the application, optical lens uses water white transparency light-transmitting materials, and such as PC, PMMA etc., case ring is using vacuum aluminum-coated
PC materials, heat dissipating housing use aluminum alloy material, LED circuit board use aluminum substrate or the preferable material of other heat conduction.In the application
Each component uses specific materials, can not only improve the hot spot molding effect of optical lens, moreover it is possible to improve integral heat sink effect；Have
It saves material, reduce cost, reduce the advantage of weight.
The operation principle of the application is：When connect LED circuit board on circuit when, dipped beam LED lamp bead emit beam by
It reflects to form hot spot and meet dipped beam laws and regulations requirement via optical lens again after low beam reflector reflection；Distance light LED lamp bead sends out light
Line pools the light beam more concentrated to form hot spot into crossing optical lens and reflecting again and meet distance light method after high beam reflector reflects
Rule require.
A kind of projection-type LED single vision lens assemblies of the utility model use dipped beam LED lamp bead+low beam reflector+optics
Lens realize the control of low-beam function, simple in structure, reliability is high, light efficiency utilization rate is high, low cost without using baffle,
