Tech-Talks BREGENZ - Prof. Ruairí O'Brien, Founder of Ruairí O'Brien Lighting Design
Ruairí O'Brien, associate professor and head of the Architecture and Visual design department at the German University in Cairo and CEO of Ruairí O'Brien. Architektur. Licht Raumkunst, surprised and delighted the audience with his lecture at LpS 2016 when he talked about allowing darkness. He expressed the same sentiments in a caption for a figure in the proceedings booklet: "The future in Dresden is not lighting excess - the future is Re-Darkness with intelligent SSL concepts." This year, Ruairí held two lectures at TiL in which he emphasized how important a thorough application of light is in respect to culture, ethics, and environment. In addition to his work, these interesting statements made it made a Tech-Talk Bregenz with him a top priority.

A New LED Controller Technology to Expedite the Next Level of Smart Lighting
Lighting installations that use artificial lighting and often deemed more comfortable and energy efficient are generally referred to as "Smart Lighting". While no clear definition exists "Smart Lighting" has become a common catch phrase. Kurt Marquardt, Senior Director LED Lighting Systems and Product Marketing, Infineon Technologies has a more accurate definition. For him, the term "smart lighting" describes the capability of the lighting system to adapt automatically to the needs of the users and the room. He presents an alternative way to implement smart lighting systems, using the new XDPL8221 digital LED-driver IC [1].

The Adverse Ecological Impacts of Light Pollution: LEDs' Role in Mitigation
With the negative effects of artificial light at night on ecosystems increasingly well-understood, attention is now turning to the ways in which these impacts can be mitigated through uptake of novel technology and lighting strategies. Dr. Callum J. Macgregor, post-doctoral research associate at the Department of Biology of the University of York, and Dr. Darren M. Evans from the School of Natural and Environmental Sciences of the Newcastle University, discuss the current evidence for costs and opportunities associated with uptake of LED lighting and highlight important directions for future investigation.

ALLOS and KAUST Are Working on High Efficiency Nitride-Based Red LEDs on Si
ALLOS Semiconductors has engaged in a collaboration with Prof. Ohkawa and his team at King Abdullah University of Science and Technology (KAUST) for realizing high efficiency nitride-based red LEDs on large diameter silicon substrates. In the collaboration the teams are addressing fundamental issues like the large lattice mismatch and the quantum-confined Stark effect (QCSE) which are preventing the adoption of red nitride-based LEDs for practical industry usage. In particular, for the emerging field of micro LED displays there is a strong demand to enable red LEDs on large diameter wafers in addition to the established blue and green color LEDs in the nitride system in order to reduce manufacturing complexity and cost.

Active Grow Launches UL Listed LoPro Max Horticultural Luminaires for Commercial and Home Growers
Active Grow, the sustainable horticultural lighting manufacturer, is proud to announce the launch of its LoPro Max 640W and 320W horticultural luminaires. These lightweight, UL Listed fixtures conveniently replace 600-1000 W and 400-600 W HPS lights in vertical racking or sea of green commercial applications, using nearly half the energy and producing half the heat. The concealed-driver design means no messy cabling or bulky external drivers. The ultra-thin profile (just 2.47") allows the luminaires to go to work in spaces with minimal vertical clearance. Integrated dimming and a tool-less installation make these fixtures perfect options for home growers with tents or hydroponic benches.

IES and IUVA Collaborate to Publish ANSI Standards for Measuring Ultraviolet C-Band (UV-C) Sources Used for Disinfection
The Illuminating Engineering Society (IES, est. 1906) and the International Ultraviolet Association (IUVA, est. 1999) have partnered to assemble experts in the measurement of ultraviolet C-band emissions (UV-C) to develop American National Standards for the measurement and characterization of UV-C device performance. UV-C devices for healthcare and personal care have proliferated in recent years, particularly during the COVID-19 pandemic, despite the absence of standards to enable accurate measurements and comparisons of the products. Through this partnership IES and IUVA aim to cooperatively promote awareness of and improve the application of ultraviolet "disinfection" technology in the healthcare system, initially through the development of standardized methods of measurement of ultraviolet "disinfection" products including UV lamps, luminaires and lighting/radiating systems, utilizing both discharge (e.g. low-pressure mercury and xenon) and solid-state (e.g. light-emitting diode) technologies.
