DIGITAL BEAM CHANGE IS THE LATEST TOOL IN THE LIGHTING DESIGNERS TOOLBOX

We start with the LED source, pairing it with the right optic to harness the light, and maximise performance.  LEDs have developed significantly, with the latest variants offering high efficiencies with excellent output and colour rendering to deliver a premium quality of light.  We work with the latest European brand  LEDs to deliver market leading performance in terms of output, efficacy and colour rending.

The optic needs to create the tightest beam possible before it passes through the liquid crystal lens, so we use a 10 degree optic specifically designed for the light emitting surface of the LED. Our optics deliver over 92% lens efficiency and produce the best luminous efficiency in the world.

The light is then passed through a liquid crystal  lens from Lens Vector, and then by applying an electrical current, the beam can be changed. from 10 to 50 degrees.  This sounds simple, but making this work smoothly, evenly and effectively is not just a forgone conclusion.  We've spent significant time and effort tuning this to be just right, combining the LED, optic, liquid crystal lens and electronics to ensure outstanding results.

All this ground breaking technology is only useful if it con be powered and controlled effectively, and by working with our technology partner Eulum Design, our electronics is controlled by Dali or wirelessly with companies like Casambi.  All the electronics is miniaturised to enable us to build fully integral luminaires in a modular format to enable simple interchange in the future.

So yes, the beam angle on our products can be controlled digitally via dali or wirelessly with brands like Casambi, but how smooth is the dimming - can you see clear steps when you change the beam?  Does the light become distorted, or are there colour shifts across the beam as it dims or changes colour?   We make sure the lit effect is perfect across the dimming, beam and colour range.

The LED, optic and liquid crystal lens need to be optimised to ensure a smooth and even beam, and the Genius and Air modules ensure just that.   Every aspect is considered to deiliver world class beam quality, just as you and your clients would expect. 

We only work with sources at 90 CRI or above, and have some specific products at 98 CRI where the subject needs to be near perfectly illuminated.  We're also experimenting with peaking certain colours within the spectrum too, to maximise rendering and efficiency too.

LED efficiencies still continue to amaze, with some sources now capable of achieving an  initial 200 lumens per Watt.  The progress which has been made over the past 20 years, since the initial 18 lumens per one Watt Luxeon LED is phenomenal, and although the days of exponential efficiency steps have gone, there are still significant and important gains to be had by using the very latest technologies.
