Light projection technology

Xray Vision light projection technology enables the light produced by an LED or HID source to be gathered and projected onto the road where it’s needed. There are two main types of projection technology: Xray Vision’s flagship quad-optic LED projection technology, and the simpler but still highly effective free-form reflector with optics-free lens.

Quad-optic projectors

Xray Vision’s unique quad-optic LED products feature technology that combines four individual optical components to gather, control and project LED light in true pencil beam and spread beam driving light patterns. The components include a free-form reflector, two lenses, and a TIR system which all work together to ensure almost 100% of the light output is captured and sent forwards.

The main benefit of this system is while traditional style LED off-road lightbars typically shine between 250m and 300m @ 1 Lux, the quad-optic technology allows products such as the 1200 Series LED linear driving light in full pencil beam to shine around 1100m @ 1 Lux.

Free-form reflectors

The earliest design of automotive headlights was simply a globe 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.

 

Xray Vision HID driving lights and a range of Xray Vision LED products 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 HID 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 HID driving lights feature a computer calibrated focal point to produce driving lights without compromise.
