Reflector Design

Optics-free Lens with Free-form Reflectors Vs Lens Optics

The earliest design of automotive headlights was simply a bulb and reflector. This created all sorts of problems with glare for
on-coming road users. Lens optics technology was developed to help focus the light from the parabolic reflector into a pattern
that illuminated the road without blinding on-coming traffic. The first headlight to use optics in the lens appeared in around
1917 – fast forward 90 years and some lighting companies are still using this same old technology. Disadvantages with lens
optics are a 10% loss in light output through the lens, some light is refracted and splayed through the lens making the pattern
less accurate, and if the lens is broken in transit it renders the light useless as the pattern is lost.

No amount of words will convince anyone, so see the photos and compare for yourself. The ones on the right are the traditional lens
optics design, whereas the ones on the left are Xray Vision optics-free lenses with free-form reflectors. You can see how the patterns
are sharper and better defined. The light within the patterns is more even and consistent, with no hot spots or dark areas. You’ll also
notice the overall output of the lights are of higher overall intensity, despite all the lights in the demonstration using the exact
same globe.

Xray Vision driving lights use the same technology as modern motor vehicles: true free-form reflectors and optics-free lenses.
This allows the driving light to display a computer engineered light pattern with virtually no light output loss.

Xray Vision lights utilise state-of-the-art manufacturing processes to produce the die-cast alloy free-form reflectors that are vacuum
aluminised to give a flawless mirror finish. The optics-free lenses are hardened quartz glass providing impeccable light transmission
without distortion or refraction. All Xray Vision driving lights feature a computer calibrated focal point to produce driving lights
without compromise.
