Sustainability in Lighting: Where are we going?
Richard Turner, Research & Development Director at Havells Sylvania

Looking back at developments in the lighting industry over the last decade, it is clear that LEDs and LED (light-emitting diode) technology have a major role to play in the future of our industry. As the technology evolves, LEDs will be used for more applications to allow building owners and managers to reap the benefits of reduced energy consumption and associated cost savings. To cope with the increased demand, the manufacturing and distribution of LED products will need to be carefully controlled and managed.

In the past, manufacturers in Asia have dominated LED manufacturing but it is simply no longer sustainable to import vast quantities of lamps and luminaire components from Asia when it comes to LED. As the electronics and technology available have advanced over the past decade, we are now able to manufacture LED lighting solutions in Europe - saving significantly on transport costs, not to mention improving the product’s carbon footprint.

We work hard to source all components required from within each local market, using local market’s resources. In this way, we are building a platform of lighting products designed, developed and manufactured for the local market but on an international scale.

It is not just about ensuring the components are sustainable, it is

 

about designing products that offer end-users final installation energy-efficiencies. The lamps and luminaires must provide the right quality of light, achieve performance targets and at the same time provide an attractive fitting. LED outperforms CFL (compact fluorescent lamps) with a lot of our fittings and, more importantly, our new products comfortably meet targets whether they are watts per square metre or lumens and watts per square metre.

Whether it is designing a true retrofit LED GS50 ES50 lamp that delivers energy savings to homeowners or whether it is designing architectural luminaires for offices - whether CFL or LED - the importance of a control system cannot be underestimated.

By integrating control systems you can achieve vast savings. For example, DALI (Digital Addressable Lighting Interface) has been talked about for years and now we are actively installing such systems. This is due to the combination of the need for energy savings (reduced running costs) and also meeting regulations, such as LENI (Lighting Energy Numeric Indicator) calculations, and building performance targets. To make the necessary savings and meet regulations it is vital that we work with architects as early as possible to design solutions that help them meet their targets.

The next step will be to develop products that take out more unnecessary materials, making them even more sustainable. For instance, developing a control system that is wireless and WiFi compatible, thereby negating the need for cabling and associated components, improving the sustainability of the solution and at the same time offering clients vastly reduced installation costs. There are also a number of new standards, such as ZigBee, in the industry and we are looking at creating a network of fittings that can be controlled from appropriate tablet devices. These will offer massive performance and control benefits as well as cost savings. Imagine the benefits for a school to operate its lighting / AV etc. from an iPad. New products will also have the

 

capacity to be retrofitted into existing schemes like our new Erlangen lamp (launching early in 2013), which will include versions that are dimmable / controllable and IP addressable. These sorts of technologies further enhance the whole lighting experience for end-users.

And what about integrating lighting into architecture? It’s a solution we are hard at work on. We are currently involved in projects where we are intelligently integrating lighting with other elements of the building infrastructure and services, such as; audio systems; AV and presentation kit; sprinkler systems; and air handling and ventilation, thus creating a truly sustainable solution plus major cost savings for the end-user. But again, the earlier we work together with an architectural practice, the more effective and cost effective the solution can be…
