Application Oriented Design This Issue of LED professional Review is dedicated to Design and Engineering and will be distributed at the 6th International LED professional Symposium +Expo in Bregenz as well as at the electronica in Munich where design and engineering topics will be discussed intensively.

Due to further developments and the degree of maturity that lighting systems are based on, LEDs and OLEDs are more and more specifically designed and adapted for dedicated applications. In order to find optimized solutions, we require a deep understanding and knowledge of the applications needs and their environments. Applications oriented design requires both cutting edge technologies that match the needs of users, and applications with certain business cases. LED professional focuses on the fields of Indoor/Outdoor Lighting, Automotive Lighting, Horticultural Lighting, Art/Museum Lighting and Medical Lighting, which are all covered by the concept of Human Centric Lighting. Let’s have a look at some examples from this issue.

LEDs Reveal Paintings Hidden in Paintings. Artists are often early adopters of new technologies that will bring their art to a new level. The two major elements that fine arts artists play with are light and materials. The article explains how Artist Clint Eccher uses LED lighting and LED technology to transform static paintings into some of the most dynamic, “living” paintings in the world.

Botanical Light Pollution. It is common knowledge that blue-rich light from high-CCT street lighting contributes to astronomical light pollution, but this is from a human perspective.

From the perspective of wild and domesticated plants, it is red light in the range of 600 to 750 nm that is a concern. Therefore, lighting designers need to understand the issues of botanical light pollution. Plants rely on red and far-red light as environmental cues on when and how to grow. From soybean fields next to highways to greenhouse lighting, lighting designers need to understand the issues of botanical light pollution.

Metrics for Detection and Measurement of Optical Flicker and Stroboscopic Effect in LED Lighting. Optical flicker is a crucial and permanent topic in LED lighting. After briefly introducing optical flicker, the author describes how it impacts the quality of LED lighting and the lack of defined parameters to measure the presence of this phenomenon in lighting products. He explains why standards and standardized measurement are required, presents metrics for its detection, and finally proposes a test program and its parameters.

The LpS 2016 will go deep into application-oriented designs. Eight workshops and forums will be dedicated to those applications: ISA Forum, Design meets Technology Forum, Alternative Light Sources Forum, Risk Transfer & Investment Forum, Tunable SSL Lighting Workshop, IoT & Artificial Intelligent Lighting Workshop, Horticultural Lighting Workshop and SSL Lighting Measurement Workshop. The complete program is in this issue.

Application orientation is not a new idea, so what’s the difference in lighting then?

Primarily, it’s the broad spectra of new technologies, the dynamics and speed of changes and the uncertainties of the acceptance of users and use cases that make us think.

Have a good read!

Yours Sincerely,

Siegfried Luger
