Abstract
The present invention belongs to a lighting light-distributing device for walking machinery (car, tractor, etc.).
The device adopts a special-shaped light control mode to form a walking mechanical glare-free illumination light distribution system, which comprises a light source, a light-controlled object screen, a reflector, a light distribution lens and the like, and is characterized in that a double light distribution mode is avoided, glare-free light distribution is directly generated, convenience and reliability are realized, and the glare-free requirement of a safe traffic illumination system is thoroughly met.
Description
The invention belongs to walking machine (automobile, tractor etc.) illuminating light distribution device.
Existing walking machine illuminating light distribution system is an anti-glare, all adopts two light-configuration mode, i.e. dipped beam luminous intensity distribution and distance light luminous intensity distributions.When the dipped beam luminous intensity distribution has other road users at vehicle front, form the closely illuminating bundle that does not cause the other side to dazzle the eyes; When the distance light luminous intensity distribution does not have other road users at vehicle front, form remote illuminating bundle.General manually near, the distance light light distributing system of (or foot-propelled) switch control that adopts.It is too big that this pair of light-configuration mode influenced by human factor, uses inconvenience: and because the distance light luminous intensity distribution produces dazzles the eyes strongly, often cause various traffic accidents, thereby fail fine solution anti-glare problem.
The object of the invention is to provide a kind of blinding free light distribution device, thoroughly solves the walking machine illuminator and dazzles the eyes problem.
The present invention utilizes Huygen's principle, adopts shaped and light-controlled mode to reach the purpose of walking machine illuminating light distribution blinding free.
Further specify below in conjunction with accompanying drawing:
Figure one is shaped and light-controlled dazzle-less head light and light distributing system schematic diagram thereof.The car light member has: 1 is filament, and voltage is 12V or 24V, and power is 50～70W; 2 is speculum, and radius is 150～250mm; 3 are control light thing screen (seeing figure two for details): 4 are lens, other focal distance f ' and be 100～250mm; 5 is the car light shell.This car light luminous intensity distribution part: 6 is luminous intensity distribution reference center, and 7 is optical axis, and 8 are the photometric screen (seeing figure three for details) apart from reference center's L=2500mm place vertical optical axis.
Figure two is made by metals such as copper or corronils for control light thing screen schematic diagram, 3 control light thing screens, wherein
Be 30～50mm, H ' is 10～15mm, H, and " be 10～15mm, M is 7～12mm, and S is 0.1～1mm, and 9 for opaque metal layer thin slice: X is 1～3mm, and Y is 15～25mm, and 10 is transparent plastic sheet; Remainder is full impregnated area pellucida (window region); Whole formation control light thing screen.
Figure three is the photometric screen schematic diagram, and the effect of car light is shown by the lighting engineering data on this screen.The L of photometric screen

2=7920mm, L
3=1500mm, H
1=250mm, H
2=750mm, H

=45 °; Each district of this photometric screen.Point satisfies ECE (the United Nations) Economic Commission for Europe and standard GB 4599.On photometric screen, I district illumination is≤20Ix; Near II district high light (75R) illumination Emax 〉=32I
xIII district illumination≤0.7≤0.7I
xIV district illumination 〉=2I
xB50L point illumination≤0.3I in the district
xAt IV district 25L and the illumination 〉=1.5I of 25R place
xThe illumination of HV (crossing the optical axis and the photometric screen intersection point of reference center) is 0.9Emax.
Characteristics of the present invention are that this device can directly produce the blinding free luminous intensity distribution, complete, convenient, Reliably, meet the car light world, national standard; Needn't adopting manually, (or pin is moving) carries out near Light, the exchange of distance light luminous intensity distribution has thoroughly solved traffic lighting system blinding free demand.
