Lighting for the Future

A new, emerging technology could change the production of LED lighting. Eulitha played a major role in its development.

The rolling green hills of agricultural north-eastern Switzerland provide few hints that the countryside of the canton of Aargau is also home to the state-of-the-art nanotechnology firm Eulitha. The small start-up is a pioneer and leader in the production of high-quality nanostructures, which manipulate matter on an atomic and molecular scale.

A Promising Future 

LED technology is a booming market which provides considerable attractive business prospects. LEDs offer many advantages over traditional bulbs because they are smaller, consume less energy and last longer. "LEDs will be the light technology of choice in the future globally," says Eulitha board member and co-founder Jens Gobrecht. Producers are therefore keen to acquire and adopt a new technology that increases efficiency and lowers costs. 

High Tech Implementing Solak's idea required the most modern techno logy. Based on the technique of a successful project at the Paul Scherrer Institute, Switzerland's largest research center for natural and engineering sciences, Eulitha was able to successfully develop a mechanism – in its highly specialized labs – which will allow firms to recreate these miniscule holes when producing LED lighting on an industrial scale. 

After a six year development phase Eulitha introduced the revolutionary PHABLE technology in 2010. PHABLE allows, for the first time, a lower-cost production system of photonic nanostructures (the creation of small holes) over large areas that are used in the making of energy efficient LEDs, solar cells and LCD displays. This is achieved with an ultraviolet photolithography technology, a system based on the same concept as the negative sheets once used in photography before digital cameras. "What we are uniquely offering is for industry to produce the wafers needed for LED production both more efficiently and at a lower cost," says Solak. Eulitha's invention is compatible with the standard industry machinery, which means that LED producers only need to adapt their existing machines. 

In 2012 Eulitha established a basis for cooperation with EVG, the Austrian headquartered technology and market leader for wafer processing equipment. "This agreement with EVG provides us with a global sales and distribution network and access to the global LED market," affirms Solak.
