Abstract
An anti-glare system for vehicular (MT1) headlamps (fig. 2a) allowing the use of high-beam without disturbing other drivers (CMT1) using: a first polarizing filter (Fp1) in the light path of the headlamp's light source (S1) at a polarization angle of 45°; and a second polarizing filter (Fp2) at the same polarization angle arranged in the field of view of the driver (CMT1 ). Correspondingly, the oncoming light of a second vehicle (MT2) moving towards the first ' vehicle (MT1 ) and having the same polarizing filters (Fp1 and Fp2) will not be transmitted; through said second polarizing filter (Fp2) reducing thus glare on the first driver (CMT1).
Description
ILLUMININATION INTERACTIVE SYSTEM AND ANTIBLINDING PROTECTION
The invention refers to an interactive system of night antiblinding protection of the drivers of all ways of transportation, air, naval or/and terrestrial when they meet glare light sources.
Driving in optimal conditions in the night time of the transport vehicle, we usually use powerful headlamps which realise the necessary illumination for visibility.
The problem is when the way of transport, moving, meet another powerful light source situated in a fix or mobile position.
In this situation the driver of the vechicle will be blind of the other light.
In the street traffic is forbidden the driver blindess which comes from opposite direction and the cars have headlamps with passing and upper beam and when the drivers meet in the night, are forced to commute on passing beam, in this moment the visibility is low.
On a traffic road, you practically are forced to drive with passing beam which does not realise the optimal visibility necessary to drive safe.
The technical proposal solution through this patent request, just solve this problem of night visibility when the way of transport driver meet another powerful light source which blinds him, thus there is accident possibility.
The technical proposal solution through this patent request allow to use all the time upper beam light without to disturbe the others traffic participants.
I know there are infrared night view devices, but i do not know own illumination in visible spectrum devices, which protect the others traffic participants.
The application area of the present invention is very large and it can apply in terrestrial, aerial or/and naval transport as in the airport, streets illumination and of some chosen objectives.
I consider that in time, this illumination interactive system and antiblinding protection, to raise the circulation safe grade, will be enacted, enforce his compulsory using in the determined area, situation which lead to application of this invention a lot, this invention will be indispensable.
Illumination interactive system and antiblinding protection, according to invention, it must applied on the own way of transport or to the other light source which it meet .
According to the optical physics, the light is an electromagnetical wave with lateral vibration on the propagation direction.
The natural light is compound from electromagnetical waves which vibrate in all the directions.
The light which vibrate after parallel directions with a given direction is named polarization light.
The technical solution, according to the invention, using the polarization light which vibrate after a well determined direction.
The physical principle uses in the present invention i explain using Fig. 1, a, b, c, and thepractical application of this physical principle, is presented in Fig. 2a, b.
In Fig. Ia, b, c, are consider three collinear points O, O', O" who are the origins of the three orthogonal reference systems OXYZ, O'X'Y'Z' and 0"X"Y"Z" with the axis OY//O'YV/O"Y", and OZ//O'Z//O"Z".
In Fig. Ia, the natural light source S is situated on the axe OX. An electromagnetical wave U is characterised by a vibration plan Pv and a vibration direction Dv.
In the plan OYZ, we delimitate the square area ABCD with the sides AB//DC//OY and AD//BC//0Z. The diagonal BD we designated with D' and the diagonal AC we designated with D" these diagonals will intersect in O point who is the physics orthogonal system origin OXYZ.
The diagonal D' makes the angle α' = 45° with axe OZ and the diagonal D" α" = 45° with OZ axe.
The plan BDEF we designated with Pv and because contains the diagonal D' and OX axe will be perpendicular on the plan ABCD and will form with axe OZ, the angle α'=45°.
We discuss the electromagnetic wave U emitted by the S source which is convey on the axe direction OX and vibrated in the vibration plan Pv. So it will have the vibration direction Dv which will be parallel with D' i mean D7/Dv.
In Fig. Ib we translated Fig. la,in a new position.
In the square area-place--AiB~GJD2--anssembling the polarizer
polarization direction Dj parallel with the vibration direction Dv of U wave so Di//Dv.
In this case, U wave generated by S source will pass trough polarizer filter Fpl because Dv//Di and will have the same vibration Pv.
Another aspect is the fact that the natural lights which will pass trough the polarizer filter Fpi will be polarizor after the direction Dj//Dv.
In Fig. lc,in the translated system 0"X"Y"Z", in the square area A"B"C"D" we assembly the polarizer filter Fp2 which will have the polarization direction D2 perpendicular on the polarization direction Dj so D1XD2.
In this situation the natural light produced by the S source polarised by the Fp] after the polarisation Di will not pass trough the polarization Fp2 because they have perpendicular polarization directions and namely Di±D2.
In Fig. 2a, b i applied theoretical principle from Fig. Ia, b, c thus;
In Fig. 2a, on the way of transport MTi is assembly one or more headlamps having with the mirror OgJ which assembly the bulb Sj which produce the natural light, that will be poralizated with the help of the polarizated filter Fpi after the the poralization direction Dj who make the OiZi axe with the angle α' = 45°.
In another direction the polarizate filter Fp2 furnished with the polarized D2 which will parallel with the polarization direction Oui mean Di //D2 and the natural lights produced by the Si bulb passing trough the polarized filter Fpi will be polarized after the polarized direction D). The way of transport driver symbolize trough CMTi viewing trough the polarized filter Fp2, because Di//D2, will see the light generated by Si.
In Fig. 2b i represented an MT2 way of transport identical with MTj but gyrate with 180°around his axe OZ who is moving in the axe sense O2X2 , contrary the moving sense of the other way of transport MTi which is moving in the axe sense OiXi.
On the way of transport MT2 is assembly one or more headlamps having the Og2 mirror where is assambly the S2 bulb which emitted the natural light and which pass trough the poralized filter Fp3 is poralized after the poralized direction D3 having the position to an angle of α" = 45° between axe O2Z2.
According the physics theory presented previous in the link with Fig. Ia, b, c, the polarized light generated by the illuminating system from MTj will not been seen by the way of transport driver CMT2 and nor the polarized light generated by the illuminating system from MT2 will not been seen by the way of transport driver CMT1 because D,1D3.
The building characteristics term of polarized filters Fpl, Fp2, Fp3 and Fp4 will exist a passing fence of polarized light from MT1 to MT2 and reverse.
As showed, the application area is very large and for every area part, it must defer to specific conditions to obtain a desired effect, but i limited analyse to road transport where it will be applicable with priority.
In time, all the cars will be equip with headlamps which have polarized filters, and the drivers will wear the special-glasses which it has polarized filters in tfre nighπδT i say previous.
The advantages using of these kind of illumination interactive systems and antiblinding protection are:
- It rise the traffic safety in the night diminish a lot the accidents, due to the blinding phenomena of the way of transport drivers.
- It rise the moving speed of ways of transport in safety conditions.
- Careless ways of transport drivers cannot blind on the others traffic participants.
- The airport, streets illumination and of other objectives is improving trough the fact it can use a great light intensity which cannot disturb.
