Rich document Troff document 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.
Rich document 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.
Rich document 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.

Rich document chemical/x-pdb Upgrade for Emergency Lighting Components Provides Smart Battery Management
Tridonic has further developed its emergency lighting units. The new generation EM converterLED BASIC MH/LiFePO4 in the low-profile housing now supports not only NiMH but also LiFePO4 batteries and operates with intelligent battery management.
Rich document 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.
