Roadway Lighting Optics for Environment Adaptive Spatial Light Distribution

Roadway lighting for different environmental conditions is a challenging task. But even more challenging is to find a solution with outstanding task efficiency for both dry and wet tarmac surface conditions. The drawback of these types of solutions is that they are usually made up of two different lighting systems. Since the two systems are not usually used to an equal degree, they age at a different rate. Solving this problem is very complex. Viktor Zsellér, PhD student, and Dr. Krisztián Samu, Senior Lecturer, both from the Budapest University of Technology and Economics, propose an optical system that solves this conundrum. Read more »

SSL Growth Strategies and USDA Corn Breeding Objectives

The SSL horticulture lighting industry has become one of the fastest growing branches of lighting worldwide. Much research has already been done in regards to horticultural SSL technology and continues to be rigorously explored. While most other inputs for plant growth are monitored and controlled based on plant needs, it is still common practice for light control to be rudimentary (on/off). Brandon Newkirk, Marketing Communications Manager at LumiGrow Inc., gives a short overview on the current state of dynamic LED lighting with a focus on USDA corn breeding trials and objectives.

Bio-Effective Lighting for Humans, Livestock and Plants

Mood lighting is often misleadingly interpreted as HCL. But HCL is much more because it includes biologically effective light that is beneficial or dangerous, depending on the correct application. While the relevant parts of the radiation spectrum may differ, light is also biologically effective for plants and animals and it is used to achieve well-defined effects. Volker Neu, General Manager LED at Vossloh-Schwabe Lighting Solutions, presents examples, discusses similarities and differences between humans, animals and plants in respect to the relevant spectra, and scrutinizes possible consequences.

Technical Aspects Regarding the Equipment of Show Caves with Modern LED Systems

Caves have an almost magical attraction over people, drawing them again and again into their depths. The first electrification started in the 19th century, culminating in today’s digitalization and “LEDification”. Vladimir Vashkevich, Technical Manager at Cave Lighting CL GmbH & Co KG, describes the tough requirements on luminaires and the whole installation. He explains the advantages for the operators and the ecosystem and finally discusses solutions, practical examples and future prospects. Read more »

LuxLive and SILE Sharpen Focus on End-Users

On November 23rd and 24th, as in previous years, LuxLive was held in the Excel Center close to London’s City Airport. This year, for the second time since the merger of Revo Media and Pennwell, LuxLive and Strategies in Light Europe were co-located. Arno Grabher-Meyer, Editor-in-Chief at LED professional, summarizes his impressions of the event, picking out the more technical oriented lectures held in the different "arenas". Read more »
