WEBINAR "Secure Smart Lighting: Unlocking a Building's IoT Potential"
Smart lighting does more than illuminate a space. Beyond energy conservation, a smart lighting system can serve as the infrastructure for building automation, and data collected from the smart lighting system are used for advanced applications such as space optimization, building security, and mobile asset tracking. With these new use cases, requirements for a commercial-grade smart lighting system are changing and security is becoming top of mind. This webinar, sponsored by Arm Ltd., is for LED manufactures, lighting control/sensor providers and system integrators, covering key considerations for commercial smart lighting systems including connectivity, interoperability, and end-to-end security.

LED Engin Introduces World’s First 50 W Seven-Die LED Emitter
LED Engin, an Osram business, has unveiled the LZ7 Plus, the world’s first 50 W seven-die LED emitter. The trend in stage lighting fixtures has evolved from not only delivering ultra-bright light with narrow beam, but also creating more sophisticated color schemes and high CRI white. LZ7 Plus is uniquely designed to address this trend, featuring seven high-power dies in six colors, which can be individually controlled to deliver intense, saturated colors, as well as high quality white light as a result of color mixing. The LZ7 Plus can be used in various stage fixtures, such as static and moving head wash fixtures, as well as profile fixtures.

LED Lighting Requires New Approaches in Optics
LpR 67 Article, page 88: Even though LED technology has been established LEDs still need new approaches in electronics, thermal management or optics to make complete use of their advantages. Marek Škereň, Chief Technology Officer of IQ Structures, explains how new optical devices, with the trade name Nanoptiqs, based on principles of diffraction are applied to achieve improved performance of white light illumination systems. This unique solution is based on full control over the modulation of material and geometric properties of the optical elements at a nano-level. A combination of complex transmission diffractive elements, with specially designed systems of micro-reflectors (produced using an innovative mass-production technique) is also presented as a promising flexible building unit for the construction of new generation luminaires.

A Study on Aerosol Jet Printing in LED Module Manufacturing
LpR 68 Article, page 38: LED module manufacturing technologies have certainly improved over the last few years but the requirements have also increased. More components are packed on today’s modules causing additional thermal stress, and, at the same time, the demand for lower cost challenges module manufacturers. So the (re-) search for new materials and new manufacturing processes and manufacturing technologies is still on. Paul Hartmann, Director of the Institute of Surface Technologies and Photonics at the Joanneum Research Forschungsgesellschaft m.b.H., and his team, Andreas Rudorfer, Martin Tscherner, Christian Palfinger, Frank Reil, Franz P. Wenzl with Ioannis E. Seferis, Eugeniusz Zych from the Faculty of Chemistry of the University of Wroclaw investigated the opportunities of aerosol jet printing and proved the applicability for alternative ways of phosphor deposition and integration and to replace wire bonding of dies.
