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.

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.

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.

UV LED Technology for Emerging Applications in Agriculture
The Ultraviolet (UV) LED market has expanded five-fold in the past decade and is projected to grow to over $1 billion by 2025. A key trend expected to influence the market is the ability to expand into new applications, including agriculture. UV light, at proper frequency and dose, can increase the production of active substances in medicinal and traditional plants and it can also help maintain a healthy growing environment. But to fully take advantage of UV LEDs, some major re-design considerations are required. Terrance Berland, CEO of the Violet Defense Group, the parent company of Violet Gro, will explain which considerations these are; for instance, why it is crucial to incorporate the appropriate lens material.

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
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.

UV-Light for Plant Development
Commentary from LpR 68: Since the development of the incandescent lamp, greenhouse farmers have been using electric light sources as a supplement to natural sunlight. Initially, light intensity was the major concern. Later, growers learned to manipulate plant development by altering the power distribution of the light spectrum for added value such as taste and appearance.
