Further, the longitudinal cross-section curvature of the low beam reflector is followed successively by k from top to bottomOn、kIn vertical、kUnder, the kOn> kIn vertical>kUnder;The lateral cross section curvature of the low beam reflector is followed successively by k from front to backBefore、kIn cross、kAfterwards, the kIn cross>kBeforeAfter=k.
The low beam reflector of the projection-type LED single vision lens assemblies of the application is gradual change ellipsoidal surface shape, the shape Low beam reflector the light of reflected illumination on the mirror to optical lens can shine out comprehensively, and low beam reflector is for receiving Collect and specular scattering is above with the light at rear, greatly reduces the scattering energy consumption of light, keep the light that LED lamp bead is sent out complete Portion is sent out by the optical lens in front, under same energy consumption, greatly improves lamp degree of illuminating, and is improved lamp and is shone efficiency.
In light source difference, different hot spot effects, the reflection of optics light-configuration mode plus refraction, dipped beam LED light source hair are formed The light gone out completes light distribution by being reflected by optical lens after low beam reflector light distribution, and dipped beam completes optics light distribution without gear Piece, most energy can be converted into effective light, effectively about be higher by percent 30 than conventional belt catch with light utilization efficiency; Optical lens is the optical lens of special (passing through optical design), and the light that dipped beam LED light source is sent out is matched by low beam reflector It is reflected by optical lens after light and completes light distribution, be integrally formed when baffle is with fansink designs, reliability increases precision and carries Height reduces production process.
The simpler design structure of single vision lens of the application, more collects optical energies and concentration is emitted to optical lens The hot spot for forming needs after on mirror after light distribution increases substantially LED light source light efficiency utilization rate, reduces energy consumption;It, can without catch To reach national relevant laws and regulations requirement under lower energy consumption, manufacturing cost further decreases.
LED circuit board is fixed in mounting base, improves the installation fastness of LED circuit board, while improving overall structure jail 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, And it is easy-maintaining, low energy consumption, is suitble to range wide.
