Abstract
When driving at night on unlit roads drivers can experience a temporary reduction in vision as the pupils react to changes in incident light. The present invention is designed to minimise this temporary reduction in night vision due to changes in incident light, approaching headlights etc. The night driving aid comprises an array of LEDs that provide exposure to low power light radiation at around 480nm (blue/green). The 480nm wavelength is the wavelength at which the pupil is most responsive to preconditioning therefore assisting the driver to visually respond to rapid changes in incident light. The LEDs are deployed in/on the vehicle within the driver’s field of vision but not obstructing their forward or reverse (via the rearview mirror) vision. Additionally, the night driving aid may be worn directly by the driver as an integrated night driving glasses system.
Description
Night Driving Aid Driving at night can be challenging especially on unlit roads.
In addition to the normal driving hazards major problems associated with night driving are:- * Being dazzled by the headlights of vehicles approaching. Reflected headlights in the rear-view mirror from vehicles travelling behind.
* Depth of perception as it's much harder to judge speed and proximity of approaching vehicles and other road users.
* Light to dark transition from lit to unlit road sections * Visibility on unlit roads headlights give illumination for approx 30 metres, it takes approximately 1 second to travel 30 metres at 60 mph.
This invention is designed to provide a solution to minimise these hazards and provide safer night time driving experience.
Whcn driving at night on unlit roads drivers can experience a temporary reduction in vision as the pupils react to the increase in incident light due to approaching headlights of oncoming vehicles and/or through the pupil reaction to reflected headlights in the rear view mirror, etc. This effect is negated when driving on lit roads as the pupils have already reacted to the higher levels of ambient light greater than provided by own vehicle's headlights and illuminated instruments.
Functions of the Pupil Reduction in optical aberrations Minimises optical aberration in the lens and cornea by limiting the light rays entering the eye.
Glare and aberration commonly occur with a large pupil in darkness.
Control of retinal illumination Response to changes in lighting maintains constant retinal illumination.
Facilitation of light or dark adaptation with abrupt changes in lighting * Depth of focus Constriction of the pupil reduces refractive error and increases depth of focus.
This invention is designed to minimise this temporary reduction in night vision due to the driver's eyes reacting to temporary increase/decrease in illumination through the othcr vehicle headlights and changes to ambient street lighting This is achieved by preconditioning the driver's vision through exposure to low power light radiation at around 480nm (blue/green). The 480nm wavelength is the wavelength at which the pupil is most responsive to preconditioning therefore assisting the driver to visually respond to rapid changes in incident light.
The exposure produces an effect similar to the well known 'glare illusion pupil size reduction' minimising the pupil's need to react to the increase in illumination.
Additionally, reducing the pupil's size in low light conditions has the effect of improving the 'depth of perception' a smaller pupil increases the depth of focus of the eye's optical system, similar to the known pinhole effect of camera lenses.
The invention can be deployed in various configurations including but not limited to * Preinstalled in a new vehicle in the rear view mirror and/or above or below the windscreen (windshield)/drivers side window(s) or any combinations of these. Powered from the vehicle's internal power source.
* As a retrofitted car accessory deployed as in item 1 above.
Powered by either external battery of via plug into the vehicle's internal power source.
* As part of night driving glasses either prescription or otherwise. Powered by battry Technical Notes (preconditioning of driver vision) * These responses are driven primarily by stimulation c/ photosensitive retinal ganglion cells (pRGCst that are most sensitive to short-wavelength (-480 um) blue light.
* Rods and cones were the only known mammal photoreceptors until the discovery of tnelanopsin, a photopigment with a peak of sensitivity (Amax) at 480 nm, which is expressed in the intrinsically photosensitive retinal ganglion cells (ipRGC7s) * Itelanopsin expressing retinal ganglion cells represent a third class of ocular photoreceptors and are involved in irradiance detection and non-image-forming responses to light including pupil constriction * typical pupil response 4hz (max to min)
Claims (1)
- Claim 1 The preconditioning is achieved through exposing the driver to a low power narrow wavelength of light at around 480nm (blue/green). The 480mn wavelength is the wavelength at which the pupil is most responsive to preconditioning assisting the driver to visually respond to rapid changes in incident light Because the driver's eyes are subject to preconditioning of the pupil miosis (constriction of the pupil) the 'depth of perception' is also normalised across a rage of night driving light conditions The invention consists of an array of LEDs having a wavelength centred amound480nm. The LEDs being deployed in/on the vehicle within the drivers field of vision but not obstructing the drivers forward or reverse (via the rear view mirror) vision approximately inlinc with the drivers normal forward line of sight.Typical deployment options include but are not limited to * Rear view mirror deployment, providing protection from headlights of following vehicles.* Above the windscreen (windshield).* Between the dashboard and windscreen (windshield).* Above quarter light (driver side).* Below quarter light (driver side).* Side window deployment.NB Final deployment arrangement will be dependent upon vehicle type and if the installation is integrated within a new vehicle or is deployed as an after manufacture accessory.It is also expected that the preconditioning system LEDs lumens output will also be adjustable in preinstalled systems as part of the vehicle's instrument lighting control systems. In systems installed as an after manufacture accessory via a separate driver control.Claim 2 Additionally, the system can be worn directly by the driver as part of an integrated night driving glasses system.
