Abstract

The headlights of a first car have lenses which polarise the light in a first direction. A second car has a windscreen, pull-down visor or rear view mirror or the driver wears glasses such that the light seen by the driver is polarised in a second direction. Thus the intensity of the light from the first headlights is reduced. Similar spectacles may be worn by pedestrians to avoid dazzle.

Description

GLARE REDUCTION DESIGN Introduction This invention relates to the use of two separate single axis polarised lenses separately arranged to reduce glare to drivers from head lights of other motor vehicles.
Whilst the polarisation of light is not a new concept the inventive step of this application produces safety benefits for all motorists.
The invention allows amount of light viewed from head lamps of other vehicles to be reduced without effect upon the light observed from the drivers own vehicle.
This is achieved by separately polarising the light through a differing single axis at the source and receptor.
This application comprises two applications of the same technology.
(i) Controlling light viewed form following vehicular head lamps.
(ii) Controlling light viewed from oncoming vehicular head lamps.
The specific embodiment of the inventive step will now be described by way of example with reference to the accompanying drawings fig's 1, 2, and 3 in which: Fig 1 Figure 1 shows in elevation the arrangement where light is reduced to the drivers eyes of an oncoming vehicle.
Light from head lamp 2 is polarised through a single axis polarised lens attached to the head lamp.
Light received through glasses 3 is polarised through a single axis polarised lens rotated on a different axis to that of lens 2.
Light viewed through the second polarised lens 2, is now reduced by polarisation and the glare from the head lamp 2 is similarly reduced.
Fig2 Figure 2 shows in elevation the arrangement where light is reduced to the drivers eyes from the head lamps of a following vehicle.
Light from head lamp 2 is polarised through a single axis polarised lens attached to the head lamp.
Light reflected by rear view mirrors is polarised through a single axis polarised lens 1 rotated on a different axis to that of lens 2 attached to the mirror surface..
Light viewed from the second polarised lens 1, is now reduced by polarisation and the glare from the head lamp 2 is similarly reduced.
Fig 3 Shows the polarisation of light from the light source 4, through head lamp lens 2 (the emitted light).
The emitted light is observed through mirror or glasses lens 1 or 3 into eye 5 (the light receptor). The differing axis's ofthe two separate lenses reduce the observed light by polarisation.
The single axis polarised lens of mirrors 1 and glasses 3 should be arranged on the same axis

Claims (2)

  1. CLAIMS 1. The concept of this application constitutes an inventive step with the benefits of improving road safety by reducing glare from head lamps of other vehicles.
  2. 2. Light emitted from head lamps of following vehicles viewed from the mirror 1 through glasses 3 through lens on the same single axis will not be reduced further.
    3 Light emitted from the drivers own vehicular head lamps observed through polarised glasses will not be reduced if the head lamps 2 and glasses 1 are on the same single axis.
    4 The lens 1 maybe polarised on the mirror surface or through the transparent material over the mirrored surface..
    5 The lens 2 maybe polarised to either the reflector surface, the head lamp glass or with the introduction of an additional lens to the head lamp.
    6 The lenses 3 may comprise glasses worn by the driver or a polarised area over the vehicle windscreen or pull down visor.
    7 Pedestrians may where the glasses 3 and avoid being dazzled by headlights of motor vehicles.
