At one time, the discussion of LEDs was one that would split a room, with some lighting professionals seizing the opportunity to work with the light source whilst others were far less convinced by the quality of light offered. Though many are still sceptical of some aspects of LED, there is no denying that the continuing challenge of sustainability is being excellently tackled by the technology.

Paul Davidson MSL&L, Technical

Trainer and Sales Development Manager for Aurora, explains how the development of LEDs is growing at a phenomenal scale; “Solid state lighting technology is on an exponential drive of development. The amount of light being produced is increasing at a rate of 2,000% over each decade, while the cost of producing that light reduces by 90% over the same ten-year period.” This surge in LED technology is well deserved, as LEDs offer an excellent opportunity to create a powerful solution for many applications; “The focus of LED is at source and is 100% efficient,” explains Davidson. “So an LED with a lower lumen output than its equivalent conventional light source delivers either the same or greater levels using less power.”

Using LEDs offers the opportunity for huge energy savings, which in turn can save the user a lot of money over time. Philips is just one company that has been championing the use of LEDs as a positive decision for some time; “The economic and environmental benefits of new LED lighting are huge, as a global switch would bring electricity savings

worth €128 billion per year, and carbon footprint reduction of 670 million tons”, says Harry Verhaar, Head of global Public & Government Affairs at Philips Lighting. These figures make it easy to understand why a number of companies in recent years have taken to LED lighting solutions to achieve sustainability targets and save money after fairly short-term payback periods. Saving money and energy are positive aspects of LED fixtures, but they are not the only benefits, as Verhaar explains; “The social benefits of innovative LED lighting will really move the needle to sustainable development. A global LED city trial led by The Climate Group shows that 80% of people feel safer in cities with LEDs. In offices you see improvements in productivity, and examples of dynamic lighting at schools result in double-digit improvements in learning effectiveness. Thus, despite the necessity and urgency to act on global sustainability challenges, these social benefits will inspire us to act on a much larger scale, and reap the benefits in our quality of life.”

As touched on by Verhaar, the use of LEDs in exterior applications can have a positive effect on the surroundings. A number of companies have invested significant time and effort in researching the implementation of LEDs for outdoors, and there are now a number of products available that are bringing LEDs to the streets. Selux’s stand at Light+Building was a wonderful exploration of the potential of LEDs, and one of the stars of their stand was the AVANZA range of high-powered

exterior LEDs. The technology behind this range was a long time in the making, with the development goal of designing sustainable, high-quality light tools for sophisticated light tasks in exterior spaces. A new type of patented optics system was developed to ensure that the product was as effective as possible. Selux Cross Beam Technology (CBT) ensures homogenous lighting of traffic areas or squares by means of precise LED light guidance. With this technology, LEDs are preset in the direction of their application for targeted use of the direct light component and efficient lighting of a variety of spaces. There is also an optional Comfort Feature in the form of an optical attachment that ensures additional widening of the light density at the light exit for enhanced visual comfort should this be suitable for the application. Alternatively, AVANZA’s dark-sky friendly optics enables light to be beamed only where it’s needed. Because LED technology is constantly changing, it is important for new products to be adaptable, and the AVANZA range from Selux allows for replacement of all electrical components to ensure a high level of future security for new LED generations, while highly durable materials and an attractive design for all visible parts ensures sustainability and longevity.
