Abstract

Vehicles are fitted with headlamp lenses which are plane polarised by a coating or controllable opacity liquid crystal structure in either the horizontal or vertical plane (1) such that any light emitted by the lamp will be plane polarised. In addition the screens, windows (2) and rear view mirrors (3) are plane polarised, by a coating or controllable opacity liquid crystal structure, at some angle between 30 DEG and 90 DEG to the lenses of the headlamps. Consequently the beam of light from the headlamps of an oncoming vehicle is to a safe level, whilst all other sources of light are clearly visible. Motor cyclists helmets would be treated in a similar manner to the windscreens of vehicles and similar night driving spectacles are envisaged for drivers. Stick on plane polarised filters or controllable liquid crystal structures, for headlamps, windscreens, windows and mirrors, may be provided. <IMAGE>

Description

DESCRIPTION This invention relates to a system for the elimination of headlamp glare whilst night driving.
Headlamp glare, particularly that produced by an oncoming vehicle utilising high beam or mal-adjusted headlamps is a well known hazard of night driving, a hazard more-over against which a driver has little or no defence.
The invention requires that all vehicles are fitted with a system such that 3600 glare elimination is achieved.
The system envisaged is that all vehicles are fitted with headlamp lenses which are plane polarised by a coating or controllable opacity liquid crystal structure in either the horizontal or vertical plane, such that any light emitted by the headlamp will be plane polarised. In addition all the screens, windows and rear-view mirrors are to be plane polarised by a coating or controllable opacity liquid crystal structure at some angle between 300 and 900 to the lenses of the lamps. Any light emitted from a lamp fitted with such a lens would be significantly reduced when viewed through a windscreen, window or rear-view mirror, treated as described. All other sources of light would remain clearly visible.
In a further embodiment, motor cyclists helmet visors are treated in the same manner as windscreens, as are night driving spectacles.
In another embodiment, stick on plane polarising filters or controllable opacity liquid crystal structures are applied to the headlamps, windscreens, windows and mirrors, the polarisation being disposed as described above.
FIGURE 1 Illustrates the treated windscreens and side screens 2 and the coated headlamps 1.
FIGURE 2 Illustrates the rear view showing the rear windscreen and side screens 2 and wing mirrors 3.

Claims (7)

1. A headlamp lens coated with a polarising material or a controllable opacity liquid crystal structure at some angle to the perpendicular.
2. A windscreen, rear screen and side screens coated with a polarising material or controllable opacity liquid crystal structure being at some angle between 300 and 900 to the coating of the lens in claim 1.
3. Any external or internal rear-view mirrors coated or fitted with controllable opacity liquid crystal structure as in claim 2.
4. A motor-cyclists helmet visor coated with a polarising material or controllable opacity liquid crystal structure as in claim 2.
5. Night driving spectacles treated as in claim 2.
6. A stick on polarising filter or controllable opacity liquid crystal structure which is orientated in the same manner as the lens in claim 1 and capable of being affixed to the standard (original type) headlamp.
7. A stick on polarising filter or controllable opacity liquid crystal structure the coating of which is orientated in the same manner as the lens in claim 2 and capable of being affixed to a standard windscreen, windows and rear view mirror.
