Abstract

Light from the car headlamps is polarised and viewed through a polariser rotated 90{ from the plane of the light so as to prevent dazzle. The polarising viewer may be the windscreen or spectacles.

Description

BRIGHT BEAM SYSTEM This invention concerns a vehicle drivers ability to see clearly whilst driving at night in the close proximity of other vehicles.
With technology moving on, it is possible to use the Xenon light system with an illuminating power of more than twice the standard halogen bulbs.
This invention enables us to use developments to their fullest potential. Up until now manufacturers have had to make allowances for oncoming vehicles by cutting the area of the projected beam as far away as possible form the oncoming driver, whilst compromising the field of vision available.
The answers and basis of this invention is the use of polarised light.
The headlight lenses of the vehicle are manufactured using glass or plastic, which has been through a process of polarisation, and emits light through one plane.
If this emitted light is viewed through another polarised glass, but having been turned through 90 degrees, the light will be unable to penetrate through to the viewer.
This invention can be achieved either as built into new vehicles by means of polarised headlamp lenses, polarised windscreen glass, and polarised glass all round, or as an addition to any vehicle by means of plastic headlamp lens covers, and polarised night driving spectacles.
As a driver of a vehicle fitted with a bright beam system I would be able to use my headlights at maximum illumination whilst encountering other similarly fitted oncoming vehicles. I would be in a position to illuminate the oncoming vehicle and to have vision well beyond the vehicle so enabling me to see clearly any obstructions or hazards ahead.
Because of the polarisation plane, the headlights of the oncoming vehicle would not give any dazzle whatsoever.
It would become immediately apparent however, if the oncoming vehicle were not fitted with a bright beam system, as the emitted light would appear as normal light and as such adjustments would have to be made as they are with our existing lighting system.

Claims (2)

  1. CLAIMS 1. A headlight system to enable the user a clearer view of the road ahead without being dazzled by oncoming trafic.
  2. 2. As Claimed in claim 1. The headlight lenses are manufactured from polarised glass or plastic And the emitted light viewed through polarised glass or plastic, having been turned through 90 degrees thus enabling no light to pass to the viewer.
