Design and engineering for future LED lighting systems

Lighting system design based on LED and OLED technologies is challenging. Preferred solutions have to incorporate the latest technologies, smart systems, new standards, advanced functionalities and new user behaviours. Therefore, a holistic design and engineering approach is required in order to develop successful LED Lighting Systems for the future.

The LpS 2014 covers the most important trends and visions in future LED lighting systems, from LED light sources and materials to manufacturing processes and system designs. Furthermore, the reliability and lifetime of LED lighting systems, as well as practical design approaches, will be discussed.

One of the lecture presentations will be about the development of a new colour fidelity index, called CRI2012, presented by Dr. Kevin A.G. Smet from the Research Council Flanders. Attendees will learn the theory and practical use of the colour metrics. Traditionally the CIE colour rendering index (CRI) has been used to describe the colour rendition of white light sources, however the CRI index fails to accurately predict the colour rendition of narrow-band or spiked spectra. This has increasingly become a problem with the advent of Solid-State Lighting, as the inability to correctly assess the colour rendition of these light sources might hinder the acceptance of this new lighting technology.

Another interesting presentation will be from Ralph Christopher Tuttle, Application Engineering Manager at Cree. He will present insights into the problem of the colour shifts of LED packages, and will also cover the important topic of failure mechanisms in Solid-State Lighting. “High temperature results can be used to accurately model LED behaviour at lower temperatures”, says Mr. Tuttle.

Human Centric Lighting (HCL) is a key topic in the lighting industry nowadays, promising a lot of future business potential. Dr. Walter Werner is a former System Architect at the Zumtobel Group and will present the challenges of HCL with a focus on components, controls and the networking environment. “We have some more steps to take before humans are back in the centre of interest when it comes to lighting”, he says.

For a better understanding of lighting effects on system designs, Bartenbach Lichtlabor will run a workshop covering theory and practical demonstrations on visual perception.

These are just some examples of the many lectures presented in five parallel tracks during the three event days. The full event program is available on the LpS website.
