Inventronics Expands Cost-Effective, Programmable LED Driver Family
Inventronics Expands Cost-Effective, Programmable LED Driver Family Inventronics has expanded their EUK family of programmable, constant-power and IP67 LED drivers to include models at power levels of 320 W. These new models are in addition to already extensive power level range which includes 75 W, 96 W, 150 W, 200 W and 240 W models. The EUK family is well suited for applications that do not require enhanced features such as always-on auxiliary power, controls-ready features or multiple timer dimming capabilities. By optimizing the features including isolated 0-10 V and 10 V PWM dimming, there is now a more cost-effective product that still offers design flexibility, high efficiency and a reliable performance.

Rethinking the Photometric Data File Format
Rethinking the Photometric Data File Format With increasing computing power, engineering disciplines cannot be imagined without simulations anymore. In lighting, photometric data and electronic processing of this data has become one of the most important tools for luminaire design and lighting design. This data is today provided in IES LM-63 format, a format that meanwhile has come to its limits. P. Eng. (Ret) Ian Ashdown, Senior Scientist at SunTracker Technologies Ltd., explains why the time for a change to a new standard has come and discusses the newly proposed standard and its properties in detail: ANSI/IES TM-33 respectively UNI 1603054.

Optical Designs to Improve LED Lighting Efficiency of Medical Endoscopes
Optical Designs to Improve LED Lighting Efficiency of Medical Endoscopes Lighting efficiency for endoscopic instruments has been deemed very poor, at only about 20%. While laboratory tests demonstrate that fiber optics bending is not problematic, optical simulations clearly show that lighting efficiency is strongly limited by the Étendue. Because of strong geometrical constraints in the light coupling area of an endoscope system, only a radical new optical design can provide significant improvement. Alexander Gaertner and Paola Belloni from the Faculty of Mechanical and Medical Engineering and the Steinbeis Transferzentrum Lichttechnik und Beleuchtungsoptik at the University Furtwangen discuss these issues and propose possible approaches.

Smart Design of Freeform Micro-Optical Elements for Thin Direct-Lit Luminaires
Smart Design of Freeform Micro-Optical Elements for Thin Direct-Lit Luminaires LpR 69 Article, page 64: Direct-lit LED luminaires consist of LED arrays. In order to achieve homogenous light distribution a diffuser sheet is placed at a certain height above the LED array. Usually the distance between the LEDs and the diffuser has to be greater than the distance between the LEDs on the array. To overcome this limitation, additional optical elements like freeform lenses are necessary. Christian Sommer, scientist at the Institute of Surface Technologies and Photonics of the Joanneum Research Forschungsges.m.b.H and his colleagues, Claude Leiner, Ladislav Kuna, Paul Hartmann and Franz P. Wenzl propose a smart design concept for an extremely flat, direct-lit lighting system, making use of mask-less laser direct write lithography. Read more »

Access Fixtures - New "No Light Below 450 nm" Troffers for Clean Rooms and Production Facilities
Access Fixtures - New "No Light Below 450 nm" Troffers for Clean Rooms and Production Facilities Access Fixtures has released a new LED troffer that emits no UV and no light below 450nm. Named FLAT, the troffer was designed for grid ceilings of clean rooms and production facilities that require no UV and no light below 450 nm. Prior to the advent of FLAT, clean rooms and production facilities that required no-UV lighting relied on fluorescent lamps with coatings (gold lamps) or filtered lenses to block out UV wavelengths. However, coatings and filters broke down over time, causing expensive production failures. The LED technology developed by Access Fixtures renders gold lamps and filters obsolete. Read more »

Colloidal Quantum Dots Make LEDs Shine Bright in the Infrared
Colloidal Quantum Dots Make LEDs Shine Bright in the Infrared ICFO researchers report on the development of a colloidal quantum-dot light emitting diode with unprecedented quantum and power conversion efficiencies in the infrared range. The ideal optoelectronic semiconductor material should be a strong light emitter i.e. should emit light very efficiently upon optical excitation as well as be an efficient charge conductor to allow for electrical injection in devices. These two conditions when met can lead to highly efficient light emitting diodes as well as to solar cells with the possibility to approach the Shockley-Queisser limit. Until now the materials that have come close to meeting these conditions have been based on epitaxially-grown costly III-V semiconductors that cannot be monolithically integrated to CMOS electronics.

Evaluating Performance of LED-Based Luminaires
Evaluating Performance of LED-Based Luminaires LpR 69 Article, page 48: The wide spread of performance data supplied by manufacturers make it difficult for the professional user to reach an “apple-to-apple” comparison, especially if the data is not based on standardized metrics. This is however critical for the preparation of lighting projects or tender specifications. Experts from LightingEurope have therefore developed a guidance document which recommends a fixed set of performance data for LED based luminaires, with particular emphasis to the useful life and the data which is necessary for lighting application design.

How to Use the Technologies for Adaptive Lighting
How to Use the Technologies for Adaptive Lighting The technologies to provide adaptive lighting are already in the marketplace and are accepted by some jurisdictions. Nonetheless, we have an inadequate understanding of how best to use these technologies, meaning that installations might not serve users well, and in the worst case, might lead to harm. Lighting researchers can generate the knowledge needed to support the best application of adaptive lighting technologies. The International Commission on Illumination (CIE) understands the importance and urgency to deal with problems of adaptive, dynamic and intelligent lighting in all application fields. Hence, this topic is a highlight of CIE’s research strategy. Read more »
